The following description of the embodiments of the present invention is provided for illustrative purposes, and the present invention is not limited to the embodiments described in the present application.

It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for understanding and reading the present disclosure, and are not used for limiting the conditions of the present disclosure, which will not be technically significant, and any structural modifications, ratio changes or size adjustments should be made within the scope of the present disclosure without affecting the function and the achievable purpose of the present disclosure. In addition, the terms such as "above", "below", "front", "rear", "left", "right" and "one" used in the present specification are for convenience of description only and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

Fig. 1A, 1B and 1C are schematic views of a lock box device 1 according to the present invention. As shown in fig. 1A and 1B, the lock box device 1 is a metal product, and includes: a housing 1', at least one primary lock cylinder 10 and a lock assembly 2.

In the present embodiment, the direction of entering or exiting the doorway (or inserting a target key 9 as shown in fig. 1A and 1D) is defined as the front and rear direction (as indicated by arrow X), the extending/retracting direction of the main lock 10 is defined as the left and right direction (as indicated by arrow Y), and the direction along the side of the door panel is defined as the up and down direction (as indicated by arrow Z). It should be understood that the orientations of the arrow directions X, Y, Z are used for explaining the configuration of the present embodiment, and are not particularly limited.

The housing 1' includes a case 1a, a side plate 1b disposed on the case 1a, and a cover plate 1c for covering the case 1 a.

In this embodiment, the box 1a is a rectangular groove having a receiving space S for receiving the lock assembly 2. For example, a key hole 100 is formed on the bottom surface of the case 1a for inserting and removing the target key 9 into and from the case 1 a.

In addition, the side plate 1b is disposed on the left side of the box 1a to configure the main lock 10, so that the main lock 10 can slidably enter and exit the accommodating space S. For example, the side plate 1b is a rectangular strip, and both ends thereof protrude from the upper and lower surfaces of the case 1 a. Specifically, the side plate 1b can be configured with at least one safety lock 11 and at least one pair of locks 12 as required.

In addition, the cover plate 1c is a rectangular plate and is covered in front of the box body 1a to cover the accommodating space S. For example, the cover plate 1c has a separate key hole 100 (for inserting and removing the target key 9 into and from the case 1a) and a handle hole 101, and the handle hole 101 is provided with a rotary type handle as the outdoor handle 8.

The main lock head 10 is a plurality of cylinders, the safety lock head 11 is tongue-shaped (i.e. bolt), and the auxiliary lock head 12 is triangle-shaped (i.e. bolt).

In the embodiment, the primary lock head 10, the safety lock head 11 and the secondary lock head 12 are configured according to eu regulations, the safety lock head 11 and the secondary lock head 12 are configured between the primary lock heads 10, and two primary lock heads 10 are respectively configured below the safety lock head 11 and above the secondary lock head 12. It should be understood that the various types of lock heads, such as U.S. or other specifications, are not limited to the above.

As shown in fig. 2A to 2D, the lock assembly 2 includes an active member 20 fixed to the main lock head 10, a driving member 21 capable of actuating the active member 20, an operation structure 2A linked with the driving member 21, a passive structure 2b movably disposed on the box body 1a, and an acting member 24 linked with the passive structure 2b, and the lock assembly 2 can be configured with an auxiliary structure 2c linked with the operation structure 2A as required.

In the present embodiment, the driving member 20 is movably disposed on the box 1a to drive the main lock head 10 to move together, and a corner of the driving member 20 is formed with a corner-lacking stop portion 20a (as shown in fig. 2B). For example, the driving member 20 is a horseshoe-shaped or inverted-U-shaped sheet with 2 legs (as shown in fig. 2B), a main guide post 200 is disposed on one leg, a linear groove-shaped main guide rail 102 (as shown in fig. 2B) connected to the main guide post 200 is formed on the bottom surface of the case 1a, and the stopping portion 20a is located at the corner of the other leg of the driving member 20. Specifically, a first reciprocating rod 104 configured with a first reciprocating spring 104a is disposed on a side surface of the cartridge 1a, and the first reciprocating rod 104 is sleeved with a main reciprocating hole portion 20b on the other leg plate of the driving member 20, so that the main reciprocating hole portion 20b of the driving member 20 can move along the first reciprocating rod 104 and can perform reciprocating motion in cooperation with the extension and retraction of the first reciprocating spring 104 a.

In addition, the driving member 21 is in a swing arm shape (as shown in fig. 2B and 2C) and is coupled to the bottom surface of the box 1a, and the steering structure 2a is a stacked wheel structure which is coupled to the bottom surface of the box 1a with a rectangular steering port 22 at the middle of the wheel as an axis. For example, the driving member 21 extends a shorter first arm portion 211 and a longer second arm portion 212 outwards from a driving shaft 210 (provided with a driving torsion spring 210a as shown in fig. 2B for reciprocating motion), and the control structure 2a includes a plurality of first and second wheel discs 22a and 22B (as shown in fig. 2B and 2B') stacked and locked at relatively high and low positions, and the control port 22 is exposed out of the handle hole 101 for installing the outdoor handle 8 (as shown in fig. 1A). Specifically, the first wheel disc 22a and the second wheel disc 22B are stacked in a symmetrical manner (as shown in fig. 2B', the outermost sides are the first wheel disc 22a, so that the operation principle of unlocking and locking indoor and outdoor is substantially the same), the first arm 211 extends in the vertical direction to form a vertical driving plate 211a, and the first wheel disc 22a extends outward from the peripheral surface thereof to form a control protrusion 220 abutting against the driving plate 211a, so that when the outdoor handle 8 rotates the control structure 2a through the control port 22, the driving plate 211a can be pushed by the control protrusion 220 to swing the driving member 21.

In addition, the passive structure 2b is a reciprocating structure, and includes at least one guiding member 23a and at least one elastic element 23b, such as a spring, opposite ends of the elastic element 23b are respectively connected to the guiding member 23a and the wall surface of the cartridge 1a, so that the guiding member 23a can generate reciprocating motion. For example, the guiding member 23a has at least one guiding groove 230, as shown in fig. 2B' and 2C, and the bottom surface of the box 1a is formed with at least one guiding rod 103 engaging with the guiding groove 230, so that the guiding groove 230 cooperates with the guiding rod 103 to make the guiding member 23a linearly displace, and the elastic element 23B limits the guiding member 23a to generate linear reciprocating motion.

In addition, the auxiliary structure 2C is also a reciprocating structure, and has the same composition as the passive structure 2B, i.e. includes a guiding member 23a ', an elastic element 23B ', a guiding groove 230 ', and a guiding rod 103 ', as shown in fig. 2A, 2B ' and 2C, so that the outdoor handle 8 can perform a reciprocating motion of opening and closing by the operating structure 2A and the auxiliary structure 2C. For example, the steering structure 2a forms a first steering column 221 extending across the second wheel 22B on the circumferential surface of the first wheel 22a (or the steering structure 2a has a second steering column 221 'directly linking with the steering port 22 and corresponding to the first steering column 221 to abut against the auxiliary structure 2c), as shown in fig. 2B', so that when the outdoor handle 8 rotates towards one direction, the manipulating structure 2a is rotated to make the first manipulating post 221 (or the second manipulating post 221 ') push (as shown in the pushing direction B1 of fig. 2B') the auxiliary structure 2c to perform a linear motion, and when the outdoor handle 8 is rotated toward the other direction, the steering structure 2a rotates to make the first steering column 221 (or the second steering column 221 ') push (as shown in the pushing direction B2 of fig. 2B') the passive structure 2B to perform a linear motion.

On the other hand, the acting member 24 is substantially an isosceles triangle, and an acting rotating shaft 240 (as shown in FIG. 2C) is disposed at the center thereof to be pivotally connected to the bottom surface of the cartridge 1 a. For example, one corner of the acting element 24 serves as the acting portion 241, and the other corner serves as the limiting portion 242. Specifically, the acting shaft 240 is configured with a reciprocating mechanism (e.g., an acting torsion spring 240a shown in fig. 2C), and the limiting portion 242 acts corresponding to the stopping portion 20a of the driving member 20, and the acting portion 241 acts corresponding to the guiding member 23a of the driven structure 2b, so that the guiding member 23a can form a guiding control portion 231 (e.g., a truncated-angle shape shown in fig. 2D to serve as a slideway) matching with the acting portion 241.

When the target key 9 is used to actuate the lock assembly 2 (i.e. in a normal use state), the target key 9 is inserted into the keyhole 100 and rotated to pull the active member 20, and at this time, the main post 200 is linearly displaced along the main guide rail 102, so that the active member 20 drives the first reciprocating spring 104a of the first reciprocating rod 104 to linearly displace together with the main lock head 10, and therefore the main lock head 10 can extend and retract relative to the side plate 1b to enter and exit the accommodating space S of the box body 1a, so that the position of the main lock head 10 is located at the locking position shown in fig. 2D or the unlocking position shown in fig. 2D'.

In addition, when the target key 9 is used for locking (i.e., the main lock 10 is located at the locking position shown in fig. 2D), the door can be opened by using the outdoor handle 8 for unlocking without using the target key 9. Specifically, the user rotates the outdoor handle 8 to rotate (the rotating direction R1 shown in fig. 2D) the manipulating structure 2a and push the auxiliary structure 2c, so that the manipulating protrusion 220 pushes the driving plate 211a to swing the driving member 21, and the second arm 212 of the driving member 21 pushes (the acting direction F1 shown in fig. 2D) the main stud 200, so that the main stud 200 linearly displaces along the main guide rail 102, and the main member 20 compresses the first reciprocating spring 104a of the first reciprocating rod 104 and the main stud 10 to linearly displace together, so that the main stud 10 can retract into the accommodating space S of the box 1a (as shown in fig. 2D'). When the main lock head 10 is retracted into the receiving space S of the box 1a, the stop portion 20a of the active component 20 will pass through the acting component 24, the position-limiting portion 242 of the acting element 24 will block the stopping portion 20a (as shown in fig. 2D') to stop the movement of the driving element 20, so that when the user releases the outdoor handle 8, by means of the reciprocating mechanism, namely, the auxiliary structure 2c is linked with the outdoor handle 8, the operation structure 2a and the driving shaft 210 are linked with the driving member 21, the outdoor handle 8, the operation structure 2a and the driving member 21 will return to their original positions, but the driving member 20 will remain still (the limiting portion 242 will block the stopping portion 20a) and will not return to its original position, so that the main lock 10 will still be retracted into the receiving space S of the box 1a, so as to assume the unlocked state shown in fig. 2D', and thus a subsequent user can open the door to enter and exit the doorway without operating the outdoor handle 8.

It should be understood that the principle of unlocking and locking is the same for both indoor and outdoor, so that the same way the indoor handle 8' (as shown in fig. 1A) moves the lock assembly 2 is used.

Therefore, when the lock assembly 2 of the present invention is applied to an escape door, the target key 9 can be used to lock the escape door at ordinary times to prevent people from entering from the outside, and during escape, an escaper can open the door by rotating the indoor handle 8' to quickly escape from the indoor to the outside without unlocking the door by the target key 9, so compared with the prior art, the lock box device 1 of the present invention can prevent burglary and is beneficial to escape when applied to an escape door.

On the other hand, after the escape, to return the main lock 10 to the locked position, the operation port 22 can be used to operate and lock the door without using the target key 9. Specifically, after the user (e.g. an escaper) closes the escape door outdoors (or returns indoors), the outdoor handle 8 (or the indoor handle 8 ') operates the operation port 22 to rotate the operation port 22 in a specific direction (e.g. the rotating direction R2 shown in fig. 2D '), so that the first operation column 221 (or the second operation column 221 ') of the operation structure 2a pushes (e.g. the pushing direction B2 shown in fig. 2D ') the passive structure 2B to perform a linear motion, so as to drive the control portion 231 of the guide 23a to push the acting portion 241 of the acting member 24, so that the acting member 24 swings (e.g. the acting direction F2 shown in fig. 2D '), so that the limiting portion 242 retracts to release the stopping portion 20a of the active member 20, and the active member 20 is matched with the first reciprocating spring 104a of the first reciprocating rod 104 and the main lock head 10 and springs back to the original position, the main lock 10 can extend out of the receiving space S of the box 1a (the state shown in fig. 2D). When the main lock 10 extends out of the receiving space S of the box 1a, the return mechanism of the acting spindle 240 returns to the acting element 24, and the user can rotate the operation port 22 to return the elastic element 23b to the guiding element 23a, so as to return to the state shown in fig. 2D.

Fig. 3A, 3B and 3C are schematic views of a lock box device 1 according to a second embodiment of the present invention. The difference between this embodiment and the first embodiment is that an idle rotation component 3 for stopping the operation of the control structure 2a is added, and other structures are substantially the same, so the description of the same parts is omitted.

As shown in fig. 3A to 3C, the idle rotation assembly 3 includes an actuating member 30 movably disposed on the bottom surface of the casing 1a, a toggle member 32 pivotally connected to the bottom surface of the casing 1a, a pushing member 33 movably disposed on the control structure 2a, and a driven member 34 disposed on the control structure 2 a.

In the embodiment, the actuating member 30 is a sheet stacked with the driving member 20, as shown in fig. 2B, to be operated by the target key 9. For example, one side of the actuating member 30 is provided with an upright tooth portion 30a, and the other side is provided with an upright plate-shaped actuating portion 30b, so that the actuating member 30 can be moved by the tooth openings 300 on the tooth portion 30a engaging with the tooth blocks 90 (as shown in fig. 1D) of the target key 9. Specifically, the actuating member 30 has at least one actuating slot 301 (e.g., two slots) formed between two sides thereof, the extending direction of the actuating slot 301 is perpendicular to the direction of the main guide rail 102, and at least one lever 105 engaging the actuating slot 301 is erected on the bottom surface of the box body 1a, so that the actuating member 30 can be displaced along the arrangement direction of the side plates 1B (e.g., the first actuating direction C1 shown in fig. 3B) by the cooperation between the lever 105 and the actuating slot 301. On the other hand, the operating rod 105 is also matched with the linking slot 20C of the active element 20 (as shown in fig. 2B), so that the active element 20 can be matched with the operating rod 105 to move along the extending and contracting direction of the main lock head 10 (as shown in the second actuating direction C2 of fig. 3B), wherein the first and second actuating directions C1 and C2 are perpendicular to each other.

In addition, the toggle element 32 is in a swing arm shape, and abuts against the actuating portion 30b, so that the toggle element 32 is pushed by the actuating portion 30b to swing the toggle element 32. For example, the toggle member 32 has a first arm 321 and a second arm 322 extending outward from the toggle shaft 320, the first arm 321 abuts against the actuating portion 30b, and the second arm 322 abuts against the pushing member 33. Specifically, the second arm 322 is connected to a base 31a disposed on the bottom surface of the box 1a by a retractable spring 31, so that the toggle element 32 reciprocates.

In addition, the pushing element 33 is mushroom-shaped or screw-shaped, and is connected to the second wheel disc 22b of the control structure 2a in a displaceable manner, and as shown in fig. 3C, the pushing element 33 has an embedding part 330, such as a rectangular column, and a cap-shaped force-receiving part 331 disposed at an end of the embedding part 330. For example, the second wheel 22B is a ring body having a control groove 222 (as shown in fig. 3B) matching with the pushing element 33, so that the second arm 322 actuates the force-receiving portion 331, and the engaging portion 330 displaces along the control groove 222 (as shown in the second actuating direction C2 in fig. 3B) to move in and out of the control groove 222 relative to the second wheel 22B. Specifically, the engaging portion 330 is sleeved with a push-pull spring 33a (as shown in fig. 3B), and one end of the push-pull spring 33a is fixedly connected to the force-receiving portion 331, and the other end is fixedly connected to the second wheel 22B, so that the pushing member 33 reciprocates along the control groove 222.

In addition, the passive member 34 is substantially a cylinder (as shown in fig. 3C), which is placed in the ring of the second wheel disc 22b, and the control port 22 is formed at the middle, and an idle port 340 for engaging or disengaging the engaging portion 330 is formed on the circumferential surface thereof. For example, the passive element 34 may have a second control column 221' formed on its periphery corresponding to the first control column 221. Specifically, the idle rotation port 340 and the second manipulation column 221' are disposed in a vertical orientation on the circumferential surface of the passive component 34, as shown in fig. 3C.

Therefore, the user can push the actuating member 30 to move toward the direction (the actuating direction C shown in fig. 3A) close to the operating structure 2a by the target key 9, so that the actuating portion 30B pushes the first arm 321 of the toggle member 32 to rotate (the rotating direction R shown in fig. 3A) the toggle member 32, so that the second arm 322 pushes (the acting direction P shown in fig. 3A) the force-receiving portion 331 of the pushing member 33, at this time, the engaging portion 330 extends (the acting direction P shown in fig. 3A) the operating groove 222 to engage into the idle slot 340 of the driven member 34, so that the driven member 34 can be connected with the first wheel 22a and the second wheel 22B by the pushing member 33 to form a linkage mechanism (shown in fig. 3A '), so that when the user rotates the driven member 34 by the operating port 22, the pushing member 33, the second wheel 22B and the first wheel 22a (shown in fig. 2B') will be linked in sequence, the first wheel 22a is rotated to drive the operating protrusion 220 to swing (as shown in fig. 2D) the driving member 21, so that the outdoor handle 8 (or the indoor handle 8') can operate the driving member 21 via the operating structure 2 a.

In addition, if the outdoor handle 8 is to be rotated idly (after being locked, the outdoor handle 8 is rotated idly), the driving member 21 cannot be operated by the operation structure 2a, the user can drive the actuating member 30 to move away from the operation structure 2a (the actuating direction C 'shown in fig. 3A') by the target key 9, so as to move the actuating portion 30b back, and the toggle member 32 is rotated reversely (the rotating direction R 'shown in fig. 3A') by the reciprocating motion of the extension spring 31, so that the pushing member 33 is moved back by the reciprocating motion of the push-pull spring 33A thereon (the acting direction P 'shown in fig. 3A'), at this time, the engaging portion 330 is disengaged from the idle opening 340 of the passive member 34 and retracted into the operation groove 222, so that the passive member 34 is disengaged from the second wheel 22b (the idle state shown in fig. 3A), therefore, when the user rotates the passive element 34 via the control port 22, the passive element 34 can only drive the second control column 221' to move toward the pushing direction B1, but the push member 33 cannot be linked to the second wheel 22B and the first wheel 22a, so that the first wheel 22a cannot rotate, and the control protrusion 220 cannot swing the driving element 21, so that the control structure 2a is in an idle state, that is, the outdoor handle 8 cannot control the driving element 21 via the control structure 2 a.

As can be seen from the above, the control structure 2a designs the idle rotation mechanism by the arrangement of the pushing element 33 and the driven element 34, so that if the idle rotation mechanism is not required (for example, for the indoor handle 8'), the pulling element 32 can be removed, and the pushing element 33 is permanently clamped to the driven element 34, so that the idle rotation function can be cancelled; alternatively, the first and second discs 22a, 22b are integrally formed with the passive member 34 (so that the first and second control columns 221,221 'are combined into a cylinder), i.e., there is no lost motion mechanism (as is appropriate for the indoor handle 8').

Fig. 4A, 4B, 4C, 4D and 4E are schematic views of a lock box device 1 according to a third embodiment of the present invention. The difference between this embodiment and the first embodiment is that a safety component 4 is added for the safety lock head 11 and the auxiliary lock head 12, and other structures are substantially the same, so the same parts are not described again.

As shown in fig. 4A to 4E, the safety assembly 4 includes a first driving member 41 fixed to the safety lock head 11, a second driving member 42 fixed to the auxiliary lock head 12, and a cam member 40 linking the first and second driving members 41, 42.

In this embodiment, the first driving member 41 is movably disposed on the box 1a to drive the safety lock 11 to move together. For example, the first driving member 41 is a rectangular plate body, which is vertically provided with at least one sub-guide column 410 and a mating column 412, and the bottom surface of the box body 1a is formed with at least one linear groove-shaped sub-guide rail 107 (as shown in fig. 4C) for engaging the sub-guide column 410 and the mating column 412, so that the first driving member 41 can be linearly displaced. Specifically, as shown in fig. 4B and 4C, a second reciprocating rod 106 configured with a second reciprocating spring 106a is fixedly disposed on a side surface of the box body 1a, and the second reciprocating rod 106 is sleeved in a secondary reciprocating hole portion 411 on the other end side of the first driving member 41, so that the secondary reciprocating hole portion 411 of the first driving member 41 can move along the second reciprocating rod 106 and can perform reciprocating motion in coordination with the extension and retraction of the second reciprocating spring 106 a.

In addition, the second driving member 42 is movably disposed on the box 1a to drive the secondary lock head 12 to move together. For example, the second driving member 42 is a rod, one end of which is fixedly connected to the secondary lock head 12, and the other end of which is vertically provided with at least one safety guide block 420, and the bottom surface of the box body 1a is formed with at least one safety guide rail 108 (as shown in fig. 4D) in a shape of a straight groove engaged with the safety guide block 420, so that the second driving member 42 can be linearly displaced. Specifically, a fixed arch wall 109 spanning the second active member 42 is vertically disposed on the bottom surface of the box 1a, so that the safety guide block 420 and the secondary lock head 12 are located on different sides of the fixed arch wall 109, wherein the second active member 42 is sleeved with a safety spring 42a between the secondary lock head 12 and the fixed arch wall 109, and two ends of the safety spring 42a are respectively fixedly connected to the secondary lock head 12 and the fixed arch wall 109, so that the second active member 42 can move through the fixed arch wall 109 and cooperate with the extension and retraction of the safety spring 42a to perform reciprocating motion.

In addition, the cam member 40 is a strip member that is pivotally coupled to the bottom surface of the case 1a to release or engage the first driving member 41. For example, one end of the shaft connecting portion 400 of the cam member 40 is a positioning portion 401 to abut against between the safety guide block 420 of the second driving member 42 and the fixed arch wall 109, and the other end of the shaft connecting portion 400 of the cam member 40 is a hook portion 402. Specifically, the coupling portion 400 of the cam member 40 is provided with a safety torsion spring 40a, one end of the safety torsion spring 40a is fixed on the stand 43 of the hook portion 402, and the other end is fixed on the positioning rod 109' on the bottom surface of the box body 1a, so that the cam member 40 can reciprocate by the torsion of the safety torsion spring 40a, and the positioning portion 401 cooperates with the second driving member 42 to operate.

In addition, a pea-shaped driving stopper 213 is formed on the second arm 212 of the driving member 21, and abuts against the coupling portion 400 of the cam member 40 to actuate or stop the cam member 40.

Therefore, the user rotates the outdoor handle 8 to rotate (the rotating direction R1 shown in fig. 2D) the operating structure 2a, so that the operating protrusion 220 pushes the driving plate 211a to swing the driving member 21, so that the second arm 212 of the driving member 21 pushes (the acting direction F1 shown in fig. 2D and 4C) the main post 200 and the sub-post 410, so that the sub-post 410 drives the matching post 412 to linearly displace along the sub-rails 107, and the first driving member 41 compresses the second reciprocating spring 106a of the second reciprocating rod 106 and the safety lock 11 to linearly displace together, so that the safety lock 11 can be retracted into the receiving space S of the cartridge 1 a. At this time, the driving stopper 213 of the second arm 212 separates from the axial connection portion 400 of the cam member 40, so that the cam member 40 is rotated (in the rotation direction R3 shown in fig. 4C) by the safety torsion spring 40a, and the hook 402 hooks the sub-guide pillar 410 to position the first driving member 41 (or the safety lock head 11). Meanwhile, the positioning portion 401 of the cam member 40 pushes (in the acting direction D shown in fig. 4C and 4E) the safety guide block 420 of the second driving member 42 away from the fixed arch wall 109, so that the safety guide block 420 linearly displaces along the safety guide rail 108, and the second driving member 42 drives the secondary lock head 12 to linearly displace, so that the secondary lock head 12 retracts into the accommodating space S of the box 1 a.

In addition, when the user releases the outdoor handle 8, the operation structure 2a will return to the original position, but the driving member 21 will not be actuated (because the hook 402 hooks the secondary guide post 410, the first driving member 41 cannot move, so that the engaging post 412 blocks the driving member 21 to rebound), so the safety guide 420 is moved (in the action direction D 'shown in fig. 1C) through the safety guide 108 from the outside of the bottom surface of the box 1a (e.g. indoors), so that the second driving member 42 drives the secondary lock head 12 to extend out of the accommodating space S of the box 1a, and presses (in the action direction D' shown in fig. 4C) the positioning portion 401 of the cam member 40 to approach the fixed arch wall 109, so that the cam member 40 rotates (in the rotation direction R4 shown in fig. 4C) via the safety torsion spring 40a, so that the hook 402 is disengaged from the secondary guide post 410, and at this time, the rotation force of the driving member 21 (i.e. the torsion force of the driving shaft 210) can push (in the torsion force of the torsion spring 210 a) (in fig. 4C) to push the torsion force of the torsion spring 210) to push (in the torsion) and press the torsion spring 410) C and the acting direction F4 shown in fig. 4E) of the engaging column 412, so that the first active member 41 can eject the safety lock 11 out of the receiving space S of the box 1 a. Understandably, when the driving member 21 rotates to a certain position, the driving stopper 213 will abut against the axial connection 400 of the cam member 40 to stop the cam member 40 and the safety torsion spring 40 a.

Therefore, when the driving member 21 drives the main locking head 10 and the safety locking head 11 to retract into the accommodating space S of the box 1a, the safety guide block 420 can be actuated to actuate the second driving member 42 to drive the cam member 40 to disengage, so as to actuate the driving member 21, and the safety locking head 11 is ejected out of the accommodating space S of the box 1a, so that even if the main locking head 10 does not extend out of the accommodating space S of the box 1a (as shown in fig. 2D'), the safety locking head 11 and the auxiliary locking head 12 can still extend out of the accommodating space S of the box 1 a.

On the other hand, since the auxiliary lock head 12 and the second driving member 42 can move by themselves, i.e. the outdoor handle 8 or the target key 9 is not linked, in the locked state (as shown in fig. 4A), if the user moves the safety guide block 420 from the safety guide rail 108 of the box body 1a, the auxiliary lock head 12 is only driven to retract into the accommodating space S of the box body 1a, and the cam member 40 cannot be driven to hook the auxiliary guide column 410 (because the positioning portion 401 is located between the safety guide block 420 of the second driving member 42 and the fixed arch wall 109), so that the outdoor handle 8 (or the indoor handle 8 ') can still operate, and the outdoor handle 8 (or the indoor handle 8' cannot escape) can be avoided from being stuck.

Fig. 5A, 5B, 5C, 5D and 5E are schematic views of a lock box device 1 according to a fourth embodiment of the present invention. The difference between this embodiment and the first embodiment is that the escape design of the indoor handle 8' of the box 1a is substantially the same as other structures, and therefore the description thereof is omitted.

The indoor handle 8 '(as shown in fig. 1A) is coupled to another handle hole 101' (configured corresponding to the control structure 2a as shown in fig. 1C) outside the bottom surface of the box 1A, so that the indoor handle 8 'can permanently control the control structure 2a without generating the idle mechanism as shown in fig. 3A to 3C, i.e. the idle mechanism cannot act on the indoor handle 8', so that the indoor handle 8 'can drive the driving member 21 to actuate the main locking head 10 (as shown in fig. 2D and 2D'), the safety locking head 11 (as shown in fig. 4A to 4E) and the auxiliary locking head 12 to retract into the accommodating space S of the box 1A, thereby generating the fast escape mechanism.

As shown in fig. 5A, 5B, 5C, 5D and 5E, a regulating member 5A is disposed in the cartridge 1 a.

In the present embodiment, the adjusting and controlling assembly 5a includes an adjusting and controlling member 50 (as shown in fig. 5D) coaxially (e.g. the driving rotating shaft 210) disposed on the driving member 21 and at least one adjusting and controlling post 51 (as shown in fig. 5E) formed on the actuating member 30 corresponding to the adjusting and controlling member 50, so that the adjusting and controlling member 50 rotates synchronously with the driving member 21, and the adjusting and controlling member 50 pushes the adjusting and controlling post 51 to displace the actuating member 30 when rotating (as shown in the actuating direction C in fig. 3A or fig. 5B). For example, the adjusting member 50 is an arc-shaped rod, one end 50a of the adjusting member 50 abuts against the driving plate 211a of the first arm 211 of the driving member 21, the other end 50b of the adjusting member abuts against the adjusting post 51, and the adjusting post 51 is a cylinder, so that the adjusting member 50 can move around along the circumference of the adjusting post 51 after pushing the adjusting post 51.

In addition, if there is no regulating mechanism (i.e. there is no arrangement of the regulating member 50 and the regulating column 51), since the idle mechanism is not activated and the target key 9 does not operate the actuating member 30 from the chamber, the active member 20 will touch the stop wall 53 (as shown in fig. 5E) of the braking portion 30b of the actuating member 30 when moving (as shown in fig. 2D or the acting direction F1 shown in fig. 5A), so that the active member 20 cannot be displaced, and therefore the primary lock head 10 together with the secondary lock head 12 and the safety lock head 11 cannot be activated (i.e. seized), and the primary lock head 10, the safety lock head 11 and the secondary lock head 12 still protrude out of the box 1 a.

Therefore, the adjusting member 50 pushes the adjusting post 51 to displace the actuating member 30, so that the stop wall 53 of the braking portion 30b of the braking member 30 will not stop the displacement path of the driving member 20, and the driving member 20 can be displaced smoothly, so that the main lock head 10, the safety lock head 11 and the auxiliary lock head 12 can be retracted into the accommodating space S of the box 1 a.

It should be understood that the control element 50 only needs to push the braking portion 30b of the actuating element 30 away from the displacement path of the driving element 20, so that the braking portion 30b only needs to move for a short distance (without actuating the idle mechanism), and the braking portion 30b does not need to be actuated for a long distance as the target key 9 (with the idle mechanism being actuated as shown in fig. 3A to 3C).

In addition, when the user releases the indoor handle 8', the control structure 2a will return to the original position, and the torsion spring 210a driven by the driving shaft 210 rotates the control member 50, so that the control member 50 pushes the stand 43 of the hook 402 to push the hook 402 away from the auxiliary guide pillar 410 (see fig. 4A to 4E), so that the positioning portion 401 of the cam member 40 is close to the fixed arch wall 109 to drive the secondary lock head 12 to extend out of the accommodating space S of the box body 1a, at this time, the rotation force of the driving member 21 (driving the rotation shaft 210 to rotate the torsion spring 210 a) can push (as shown in the action direction F4 in fig. 4C and 4E) the engaging column 412, so that the safety lock 11 is ejected out of the receiving space S of the box 1a, thereby eliminating the need to move the safety guide 420 at the safety guide 108, the safety lock 11 and the sub-lock 12 can be ejected out of the receiving space S of the box 1 a.

Fig. 6 is a flowchart of a lock actuation method according to a first embodiment of the present invention, and fig. 6A to 6D are schematic diagrams of fig. 6.

In this embodiment, the lock actuation method is directed to the situation that the user moves from indoor to outdoor, such as going out, leaving indoor or escaping.

In step S60, a lock, such as the lock box device 1, is provided, which has a housing 1 'and at least one lock bolt (such as the primary lock head 10, the safety lock head 11, and the secondary lock head 12) disposed on the housing 1', and a first target handle and a second target handle are disposed on two opposite sides of the lock, respectively.

In the embodiment, the lock is disposed on a door panel 6, and the door panel 6 is closed, as shown in fig. 6A.

Furthermore, as shown in fig. 6A, the first target handle is an indoor handle 8' which can permanently control the steering structure 2a, and the second target handle is an outdoor handle 8 which controls the idle rotation mechanism.

At a first time point (after the user enters the room), the latch bolt protrudes out of the housing 1 ', and the indoor handle 8 ' is rotated toward a first target direction a1 to lock the latch bolt in a locked state, such that the latch bolt cannot be retracted into the housing 1 ' by the outdoor handle 8 in step S61.

In the present embodiment, the indoor handle 8' is pulled upward (clockwise rotation based on the user as shown in fig. 6B) in the first target direction a 1. It should be understood that the indoor handle is not particularly limited in its variety, such as a pressing type (the first target direction is based on the direction in which the user lifts the handle).

In addition, the indoor handle 8' returns to its original position (the horizontal position shown in fig. 6A) after the latch is locked.

At a second time point (when the user wants to leave the room), the indoor handle 8 'is rotated in a second target direction a2 to unlock the lock bolt and retract the lock bolt into the housing 1' to be unlocked in step S62, and at this time, the user can push the door panel 6 away from the room.

In the present embodiment, the first target direction a1 and the second target direction a2 are opposite directions. Specifically, the second target direction a2 is to pull the indoor handle 8' downward (based on a user rotating counterclockwise as shown in fig. 6C). It should be understood that the indoor handle is not particularly limited in its variety, such as a pressing type (the second target direction is a direction in which the user presses the handle) and the like.

In addition, the indoor handle 8' returns to the home position (the horizontal position shown in fig. 6A) after unlocking the latch.

At a third time point (the user has left the room and closed the door 6 outdoors), the outdoor handle 8 is rotated in a third target direction A3 to extend the lock bolt out of the housing 1' to lock the lock bolt in the locked state in step S63.

In the present embodiment, the first target direction a1 and the third target direction A3 are the same direction. Specifically, the third target direction a3 is to pull the outdoor handle 8 upward (based on a user rotating counterclockwise as shown in fig. 6D). It should be understood that the outdoor handle is not particularly limited in its variety, such as a pressing type (the third target direction is a direction in which the user lifts the handle), for example.

In addition, the outdoor handle 8 will return to its original position after the latch is locked (as shown in fig. 6A, which is the horizontal position of the indoor handle 8').

In addition, when the lock box device 1 is locked, the idle rotation mechanism is activated, so that the outdoor handle 8 cannot be unlocked.

Fig. 7 is a block diagram illustrating a flow of a lock actuating method according to a second embodiment of the present invention, and fig. 7A to 7D are schematic diagrams of fig. 7. The difference between this embodiment and the first embodiment lies in the usage situation of the user, so the same parts are not described in detail below.

In the embodiment, the actuating method of the lock is directed to the situation that the user moves from the outdoor to the indoor, such as going home, entering the indoor or other situations, and the first target handle is the outdoor handle 8, and the second target handle is the indoor handle 8'.

At a first time point (the user leaves the room and closes the door panel 6 outdoors), the latch bolt protrudes out of the housing 1 ', and the outdoor handle 8 is rotated in a first target direction a 1' (as shown in fig. 7A) to lock the latch bolt in the locked state in step S70.

In this embodiment, after the lock box device 1 is locked, the idle rotation mechanism is activated, so that the outdoor handle 8 cannot be unlocked.

In step S71, the lock box device 1 is controlled by the target key 9 (as shown in fig. 7B) to release the idle rotation mechanism of the lock box device 1, so that the outdoor handle 8 can control the control structure 2 a.

At step S72, at a second time point (when the user wants to enter the room), the outdoor handle 8 is rotated in a second target direction a2 '(as shown in fig. 7C) to release the locked state of the latch bolt, so that the latch bolt is retracted into the housing 1' to be in the unlocked state, and at this time, the user can pull the door panel 6 to enter the room.

In the present embodiment, the first target direction a1 'and the second target direction a 2' are opposite directions.

At a third time point (the user has entered the room and closed the door 6 in the room), the indoor handle 8 ' is rotated toward a third target direction A3 ' (as shown in fig. 7D) to extend the lock bolt out of the housing 1 ' to lock the lock bolt in the locked state in step S73.

In the present embodiment, the first target direction a1 'and the third target direction A3' are the same direction.

Therefore, the lock box device 1 of the present invention can be used for a home door lock, which arranges the outdoor handle 8 and the indoor handle 8 ' on opposite sides to place the keyhole 100 of the target key 9 and the side of the outdoor handle 8 engaged therewith outdoors and to place the indoor handle 8 ' indoors, so that when a user is in a locked state in the lock box device 1, the user can escape from indoors quickly by pressing down (the second target direction a2 shown in fig. 6C) the indoor handle 8 ' without the need of a key or turning a twist to open the door.

Fig. 8 is a block diagram illustrating a third embodiment of a lock actuating method according to the present invention, and fig. 8' is a schematic illustration of fig. 8. The difference between this embodiment and the above embodiments is the type of the lock, so the same parts will not be described in detail below.

In step S80, an electronic lock is provided as the lock.

In this embodiment, the lock box device 1 is configured with a sensing component 8 ″ in the accommodating space S thereof, so that the lock box device 1 becomes an electronic lock, and the sensing component 8 ″ is used to link the lock bolt. For example, the sensing assembly 8 ″ includes a circuit board 80, a motor 81 electrically controlled by the circuit board 80, and a related mechanism (not shown) linked by the motor 81, as shown in fig. 8'. It should be understood that the configuration of the electronic lock is various and not particularly limited.

At step S81, at a first time point, the bolt is electrically operated (e.g. by a sensor key not shown) to extend out of the housing 1' to lock the bolt in a locked state.

At a second time point, in step S82, the lock bolt is released by an electrically controlled manner (e.g., an inductive key not shown) so that the lock bolt retracts into the housing 1' to be in an unlocked state.

At step S83, at a third time point, the lock bolt is electrically operated (e.g. by a sensing key not shown) to extend out of the housing 1' to lock the lock bolt to be in the locked state.

It should be understood that the operation of the electronic lock is not limited to the inductive key, and the user can leave the room or enter the room in steps S81 to S83.

Therefore, in the electronic lock of the present invention, the actuation function of the outdoor handle 8 can be replaced by the sensing key according to the escape requirement, and the indoor handle 8 'is still configured indoors, so that after the lock box device 1 is in the locked state, the indoor handle 8' can be quickly escaped from the room by pressing down (as shown in the second target direction a2 in fig. 6C), without opening the door by the sensing key.

In summary, the lock box device 1 of the present invention, mainly by the design of the lock component 2, can lock the escape door to prevent the entry of the people from the outside at ordinary times, and during the escape, the escaper only needs to rotate the indoor handle 8' (i.e. rotate the control structure 2a) to open the door to quickly escape from the indoor to the outside, and does not need to unlock with the target key 9, the turn button or the induction key, so the lock box device 1 of the present invention can not only prevent burglary, but also facilitate the escape when being applied to the escape door or the room door.
