Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In the description of the present embodiment, it is to be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore, should not be construed as limiting the scope of the present embodiment.

As shown in fig. 1 to 14, an embodiment of the present invention provides a lock, including a base 1, a lock 4, a linkage mechanism and a driving mechanism, wherein the driving mechanism is connected to the linkage mechanism; the lock 4 and the driving mechanism are respectively arranged on the base 1; the linkage mechanism is movably arranged on the base 1; the lock tongue of the lock 4 is separated from the linkage mechanism and the driving mechanism respectively; when the lock 4 is unlocked, an unlocked position is formed, and the driving mechanism can drive the linkage mechanism to move to the unlocked position. Referring to fig. 9, a locking tongue 30 is disposed on the lock 4, and a sliding pair is formed between the locking tongue 30 and a locking tongue groove of the lock 4, so that after the locking tongue 30 retracts into the locking tongue groove, the lock 4 is in an unlocked position, i.e., in an unlocked state; when the latch tongue 30 is extended from the latch tongue groove, the lock 4 is in the locked position, i.e., in the latched state.

In the lockset provided by the embodiment of the invention, the lock and the driving mechanism are respectively arranged on the base, the linkage mechanism is movably arranged on the base and is connected with the driving mechanism, and the lock tongue of the lock is respectively separated from the linkage mechanism and the driving mechanism, so that when the lock is unlocked and an unlocking position is formed, the driving mechanism can drive the linkage mechanism to move to the unlocking position to realize unlocking.

Compared with the prior art, according to the lockset provided by the embodiment of the invention, the lock tongues of the lock are respectively arranged separately from the linkage mechanism and the driving mechanism instead of being connected together, and the driving mechanism applies unlocking force to the linkage mechanism, so that the linkage mechanism moves to the unlocking position of the lock to realize unlocking, and the unlocking direction of the lockset is from the driving end to the locking end instead of from the locking end to the driving end.

When a lock can be arranged in the lockset, one end of the first connecting rod 9 and only one end of the two ends of the second connecting rod 10 are hinged with the blocking piece 5, specifically, when the lock is unlocked, the driving plate 2 receives unlocking acting force and moves towards the unlocking direction, and the middle part of the first connecting rod 9 is hinged to the driving plate 2, so that in the moving process of the driving plate 2, the hinge pin shafts of the first connecting rod 9 and the driving plate 2 also move towards the same direction, and then the blocking piece 5 can be driven to move to the unlocking position of the lock by virtue of a connecting rod mechanism formed by the first connecting rod 9 and the second connecting rod 10, so that unlocking is realized. At this time, the other two free ends of the first link 9 and the second link 10 may be provided with the stoppers 5, or may not be provided with the stoppers 5, and one of the two free ends needs to be fixed.

When there are two locks in this tool to lock, the one end of first connecting rod 9, and the both ends in the both ends of second connecting rod 10 are articulated respectively have fender piece 5, specifically, when these two locks are in the state of unblanking respectively, drive plate 2 accepts the power of unblanking and moves to the direction of unblanking, because the middle part of first connecting rod 9 articulates in drive plate 2, consequently, in the in-process that drive plate 2 moved, first connecting rod 9 also moves to the equidirectional removal with the articulated round pin axle of drive plate 2, then, can drive two fender pieces 5 respectively with the help of the link mechanism that this first connecting rod 9 and second connecting rod 10 constitute and move to the position of unblanking of two locks, thereby realize unblanking. In this case, the stopper 5 may be provided at the other free end of the first link 9 and the second link 10, or the stopper 5 may not be provided, and the other free end may or may not be fixed. If the other free end adopts a non-fixed mode, two-opening-one can be realized.

In order to make the structure of the lock simpler and reduce the cost, in some examples, the lock 4 can be formed with an unlocking position at the original bolt position when being unlocked.

In this embodiment, the number of the locks 4 may be three, and when any two locks 4 of the three locks 4 are unlocked, the unlocking positions can be respectively formed at the original bolt positions; the linkage mechanism can comprise a driving plate 2 and three stoppers 5 connected with the driving plate 2, the driving plate 2 and the three stoppers 5 can be respectively and movably arranged on the base 1, and the driving plate 2 is connected with the door bolt plate 3; when any two locks 4 in the three locks 4 are unlocked, the driving mechanism can drive two blocking pieces 5 in the three blocking pieces 5 to respectively move to the unlocking positions of the two locks 4 in the unlocking state, so that the lockset forms a three-lock two-unlocking lockset.

One set of structure can be used for one lock, two locks and three locks, so that the practicability is high and the flexibility is high; the condition that a lock is damaged can be realized by adopting a two-opening one-opening or three-opening two-way mode, normal unlocking can be realized under the condition that the lock or lock tongue equipment of the lock is not damaged, and the cost is saved.

In some examples, the linkage mechanism may further include a first link 9 and a second link 10, the first link 9 has a first inflection point α at a middle portion thereof, the first link 9 is hinged to the driving plate 2 by a first inflection point α, the second link 10 has a second inflection point β at a middle portion thereof, the second link 10 is hinged to one end of the first link 9 by a second inflection point β, and the first inflection point α may be disposed near one end of the first link 9 where the second link 10 is hinged and far from the other end, one end of one of the three stoppers 5 is hinged to a stopper hole disposed at the other end of the first link 9, and one ends of the other two stoppers 5 are respectively hinged to stopper holes disposed at both ends of the second link 10.

In the above embodiment, the lock includes a base 1, a driving plate 2, a first lock 4a, a second lock 4b, a third lock 4c, a first blocking member 5a, a second blocking member 5b, a third blocking member 5c, a first link 9 and a second link 10. The first lock 4a, the second lock 4b and the third lock 4c are fixedly connected to the base 1 along a set direction, and the first lock 4a, the second lock 4b and the third lock 4c can be arranged side by side in the same direction, so that a first gap is formed between the first lock 4a and the second lock 4b, a second gap is formed between the second lock 4b and the third lock 4c, and a third gap is formed between the third lock 4c and one edge of the base 1. On the base 1, a first oblong hole 41a is provided in the first gap, a second oblong hole 41b is provided in the second gap, and a third oblong hole 41c is provided in the third gap, so that the longitudinal directions of the first oblong hole 41a, the second oblong hole 41b, and the third oblong hole 41c are in a set direction. When the first lock 4a is in the unlocking position, the first blocking piece 5a and the first long round hole 41a form a moving pair along the set direction; when the second lock 4b is in the unlocking position, the second blocking piece 5b and the second long round hole 41b form a moving pair along the set direction; when the third lock 4c is in the unlocked position, the third stopper 5c and the third oblong hole 41c constitute a moving pair in the set direction. One end 9c of the first connecting rod 9 is hinged to the first baffle 5a and the first long round hole 41a through the first limit long round hole 11; the middle part of the first connecting rod 9 is hinged with the driving plate 2; the other end 9d of the first connecting rod 9 is hinged to the middle part of the second connecting rod 10; one end 10c of the second connecting rod 10 is hinged to the second gear piece 5a and the second long circular hole 41b through the second limit long circular hole 13; the other end 10d of the second link 10 is hinged to the third stopper 5c and the third oblong hole 41c through the third limit oblong hole 16. The driving plate 2 and the base 1 form a moving pair along a set direction. In practice, the first limiting long round hole 11, the second limiting long round hole 13 and/or the third limiting long round hole 16 can be replaced by a round hole or a long hole with a larger diameter, but the difference is that when a round hole with a slightly larger diameter is used, the limiting effect is unstable, the limitation on the free end of the connecting rod is easy to deviate, in some cases, a limit error may be caused, for example, in order to provide a sufficient movement space in the longitudinal direction, a circular hole having a slightly larger diameter needs to have a width direction equal to the length in the longitudinal direction, but, at this time, because the length of the connecting rod mechanism in the width direction is larger than the necessary width, the diameter of the pin head of the hinge pin shaft at the free end of the connecting rod mechanism is required to be larger, and moreover, when the link mechanism drives, the driving plate 2 is required to provide larger driving displacement due to insufficient thrust of the diameter edge of the limiting hole. If the limiting hole is designed to be a long hole, when the hinge pin shaft at the free end of the connecting rod mechanism moves to the end point of the long hole, the contact area between the hinge pin shaft at the free end of the connecting rod mechanism and the edge of the long hole is small, and although the problem that the driving plate 2 needs to provide larger driving displacement cannot be caused, the transition of the hinge pin shaft at the end point of the long hole is not stable enough, and the use comfort of an operator is easily reduced. Therefore, the limiting holes of the present embodiment preferably include a first limiting oblong hole 11, a second limiting oblong hole 13 and a third limiting oblong hole 16, respectively.

The embodiment of the invention can provide an unlocking method based on the structure of the lockset, namely the unlocking method of the lockset, and the method comprises the steps of controlling the lock in the lockset to be unlocked, thereby forming an unlocking position; and controlling the linkage mechanism to move towards the unlocking position by the driving mechanism until the linkage mechanism reaches the unlocking position, so as to realize unlocking.

In some examples, controlling a lock in the lock to unlock, thereby forming an unlocked position, may include: and controlling the lock in the lock to be unlocked so that the lock tongue of the lock retracts and forms an unlocking position at the original lock tongue position. Specifically, the deadbolt of the lock is separate from the linkage mechanism and the drive mechanism. Wherein, when the quantity of lock is three, control lock among the tool to lock unblanks for the spring bolt retraction of lock, and form at its original spring bolt position and open the position and can include: any two locks of the first lock, the second lock and the third lock in the lock are controlled to be unlocked, and the unlocking positions are respectively formed at the original bolt positions of the first lock, the second lock and the third lock. And through the direction removal of actuating mechanism control link gear to the position of unlocking, until reaching the position of unlocking, realize unblanking and can include: the driving plate of the linkage mechanism is controlled to move towards the unlocking position by the bolt plate of the driving mechanism, so that the first connecting rod and the second connecting rod of the linkage mechanism are driven to act, two blocking pieces corresponding to the two phase locks in the unlocking state in the first blocking piece, the second blocking piece and the third blocking piece of the linkage mechanism move towards the unlocking position, and unlocking is realized.

In the second situation, the second lock 4b and the third lock 4c are in the unlocked position, the first lock 4a is in the locked position, since the first link 9 is hinged to the driving plate 2 through the inflection point α, at this time, when the driving plate 2 is subjected to a horizontal leftward force, the hinge pin 15 also moves leftward, in this case, since the first lock 4a is in the locked position, the hinge pin 12 cannot move leftward, the first link 9 rotates around the hinge pin 15, and simultaneously drives the hinge pin 18 to rotate clockwise, and the hinge pin 18 also simultaneously shifts upward, at this time, the first limit oblong hole 11 provides a clockwise rotation space for the first end 9c of the first link 9, the second limit oblong hole 13 provides a clockwise rotation space and an upward shift space for the first end 10c of the second link 10, and the third limit oblong hole 16 provides a clockwise rotation space and an upward shift space for the second link 10d to rotate clockwise and shift, and finally, the second blocking element 5b and the second blocking element 5c move leftward.

In the third situation, the first lock 4a, the third lock 4c are in the unlocked position, the second lock 4b is in the locked position, since the first link 9 is hinged to the driving plate 2 through the inflection point α, at this time, when the driving plate 2 is subjected to a horizontal leftward force, the hinge pin 15 moves leftward, in this case, since the second lock 4b is in the locked position, that is, the hinge pin 14 cannot move leftward, at this time, the first link 9 translates leftward, so that the hinge pin 18 moves leftward, at this time, in order to balance the leftward movement of the hinge pin 18, the second link 10 rotates clockwise with the hinge pin 18 as a rotation center, the second limit oblong hole 13 provides a space for clockwise rotation of the first end 10c of the second link 10, the third limit oblong hole 16 provides a space for clockwise rotation of the second end 10d of the second link 10, and finally, the first gear 5a and the third gear 5c move leftward to achieve unlocking.

In this case, when the locking bolt of the lock 4 is in the locking position, the side wing 6 of the blocking member 5 cannot move to the left due to the height limitation of the bottom surface of the locking bolt 30, so that the unlocking of the lock provided by the embodiment of the present invention cannot be realized. In addition, when the spring bolt of lock 4 was in the position of unblanking, flank 6 can place in the below of spring bolt to can support and block the spring bolt, prevent that lock 4 from taking place automatic lock that falls.

In this embodiment, the pressing plate 7 includes a first pressing plate 7a, a second pressing plate 7b, and a third pressing plate 7c, and the pin includes a first pin, a second pin, and a third pin. The first blocking piece 5a is provided with a seventh oblong hole 8a along the set direction, the second blocking piece 5b is provided with an eighth oblong hole 8b along the set direction, and the third blocking piece 5c is provided with a ninth oblong hole 8c along the set direction.

In some examples, the lock may further include a fourth pressure plate 19, a fourth pin 55, and a fifth pin 26. The driving plate 2 is provided with a tenth oblong hole 20 and an eleventh oblong hole 25 along a set direction. The fourth pressing plate 19 is fixedly connected to the base 1 by a fourth pin 55. The fourth pressure plate 19 is fixedly connected to the base 1, the radial dimension of the fourth pressure plate 19 is larger than that of the tenth oblong hole 20, and the driving plate 2 is locked on the fourth pin shaft 55 through the tenth oblong hole 20, so that the driving plate 2 is located between the fourth pressure plate 19 and the base 1. The fifth pin shaft 26 is inserted into the eleventh oblong hole 25. In this case, the tenth oblong hole 20 and the 11 th oblong hole 25 can be arranged so as to guide the driving plate 2 when subjected to a force in the first direction, thereby avoiding the driving plate 2 from deflecting during the forced movement.

In some examples, the drive mechanism may include the keeper plate 3, the first shaft 52, the gear 29, and the rack 28; the door bolt plate 3 is connected with the driving plate 2; the rack 28 is arranged on the door bolt plate 3 and extends along the unlocking direction; the gear 29 and the first rotating shaft 52 transmit torque, and the first rotating shaft 52 is arranged on the door bolt plate 3; the rack 28 is meshed with the gear 29; when the first rotating shaft 52 is rotated, the rack 28 drives the latch plate 3 to move in the unlocking direction. In this case, the gear 29 and the rack 28 constitute a rack-and-pinion mechanism, and the characteristic is that the rotational power provided to the gear 29 can be converted into the linear motion of the rack 28 by means of the rack-and-pinion mechanism, at this time, since the plane of the rack 28 corresponds to the plane of the driving plate 2, when the gear 29 receives the rotational power of the counterclockwise rotation, the rack 28 engaged with the gear 29 can be forced to move to the left, and when the rack 28 moves to the left to contact the driving plate 2, the counterclockwise rotational force is continuously provided to the gear 29, and the rack 28 can be forced to the left.

In some examples, the lock may further include a second rotating shaft 39, the diameter of the second rotating shaft 39 is larger than the diameter of the first rotating shaft 52, and the second rotating shaft 39 is fixedly connected to the first rotating shaft 52, so that there is no relative rotation between the first rotating shaft 52 and the second rotating shaft 39. Normally, the diameter of the first shaft 52 is relatively small, i.e. the moment arm is short, in order to accommodate the axial bore of the gear 29, in which case the rotational force to be applied to the first shaft is large for a given torque in order to enable the gear 29 to rotate. In the case of adding the second rotating shaft 39, since the diameter of the second rotating shaft 39 is larger than the diameter of the first rotating shaft 52, that is, the length of the moment arm is increased by the second rotating shaft 52, at this time, under the condition of a certain moment, the acting force required to be applied to the second rotating shaft 39 is smaller, in other words, the required unlocking acting force is smaller. In addition, the lock provided by the embodiment of the invention further comprises a plurality of connecting handles 40, and the connecting handles 40 are arranged on the circumferential direction of the second rotating shaft 39 along the radial direction. Since the second rotating shaft 39 has a cylindrical shape, a slip phenomenon is easily generated on the side wall of the second rotating shaft 39 in the process of applying the rotation torque to the second rotating shaft 39, and the slip phenomenon in the process of applying the rotation torque to the second rotating shaft 39 can be reduced by providing the connection handle 40, so that the application of the rotation torque is facilitated.

In some examples, the driving plate 2 is provided with two guide oblong holes 21 which are opposite and inclined in the length direction; the lockset can also comprise two groups of protection components, and the protection components can comprise a limiting moving part 34 and a limiting block 31; one end of the limiting moving part 34 is hinged to the door bolt plate 3, and the other end of the limiting moving part 34 is hinged to the inside of the guide long circular hole 21; the limiting block 31 is arranged on the base 1, and a limiting bulge 32 is arranged on the limiting block;

one end of the guide oblong hole 21 corresponds to the stopper surface 33 of the stopper protrusion 32, and the other end of the guide oblong hole 21 is outwardly away from the stopper surface 33.

In the above embodiment, the lock further includes a first limiting member 34a, a first limiting member 31a, a first moving pin 37a, and a second limiting member 34b, wherein the first limiting member 34a and the second limiting member 34b are symmetrically disposed, and the first limiting member 31a and the second limiting member 31b are symmetrically disposed. The driving plate 2 is provided with a first guide oblong hole 21 and a second guide oblong hole 23. One end of the first limiting moving part 34a is hinged to the door bolt plate 3, and the other end of the first limiting moving part 34a is hinged to the first guide long circular hole 21; one end of the second limiting moving part 34b is hinged to the door bolt plate 3, and the other end of the second limiting moving part 34b is hinged to the second guide long circular hole 23. The first stopper 31a is provided with a first stopper protrusion 32a, and the second stopper 31b is provided with a second stopper protrusion 32 b. The length direction of the first guide oblong hole 21 is inclined so that one end of the first guide oblong hole 21 corresponds to the first stopper surface 33a of the first stopper protrusion 32a and the other end of the first guide oblong hole 21 is outwardly away from the first stopper surface 33 a; the second guide oblong hole 21 is inclined in the longitudinal direction such that one end of the second guide oblong hole 21b corresponds to the second stopper surface 33b of the second stopper projection 32b and the other end of the second guide oblong hole 21b is outwardly away from the second stopper surface 33 b. Taking the direction of fig. 15 as an example, once the leftward acting force applied to the bolt plate 3 exceeds the limit value, the hinge pin 36 is limited in the direction of the guide oblong hole 21, so that the stopper 34 rotates counterclockwise around the hinge pin 36 during the leftward movement, and when the stopper 34 moves to one end of the guide oblong hole 21, since the one end corresponds to the stopper surface 33 of the stopper protrusion 32, and the fixed point of the stopper 34 touches the stopper surface 33, the bolt plate 3 is prevented from moving leftward under the leftward acting force exceeding the limit value due to the limiting action of the stopper surface 33, thereby playing a role in protection.

In some examples, the stopper 31 may include a stopper fixing member 56, a pin body 37, an elastic member 47, and a blocking member 48; the limiting fixed part 56 is provided with a first through hole 57, and the plugging piece 48 is provided with a second through hole 49;

the plugging piece 48 plugs one end of the first through hole 57; one end of the pin body 37 penetrates through one end of the first through hole 57, the other end of the pin body 37 penetrates through the second through hole 49, and the elastic piece 47 is blocked in the first through hole 57 by the blocking piece 48; the pin body 37 contacts and supports the limit stop 34. Under normal conditions, due to the limiting action of the elastic element 47, the pin body 37 is in a floating state to support the stopper 34, so that the stopper 34 can be prevented from accidentally sliding down to one end of the guide slotted hole 21 to prevent the left movement of the door bolt plate 3 under the condition that no force exceeding the limiting value is received. When the force exceeding the limit value is applied, in the process that the stopper 34 moves leftward, the stopper 34 also rotates counterclockwise around the hinge pin 36 as a rotation center, that is, the pin body 37 is pressed downward, and the elastic member 47 is in a pressed state, and thereafter, once the force exceeding the limit value is released, the stopper 34 can be easily restored by the stiffness force of the elastic member 47. In this embodiment, the elastic member 47 is a cylindrical spring. In this embodiment, the contact point 38 between the pin body 37 and the stopper 34 is a hemisphere. In this case, the isotropic nature of the contacts 38 can be used to reduce wear at the contacts 38, thereby improving the service life of the pin body 37. In addition, as illustrated in fig. 15, the left contact surface of the stopper 34 is inclined from the vertex 35 to the upper right, and in this case, even if the vertex of the stopper 34 has contacted the stopper surface 33, the left force applied to the keeper plate 3 is still increased, and since the left contact surface of the stopper 34 is inclined from the vertex 35 to the upper right, it can continue to rotate counterclockwise by a small angle with the hinge pin 36 as the rotation center, thereby playing a role of buffering and improving the service life of the stopper 34.

In some examples, the top of the first through hole 57 may be provided with an inward first annular shoulder 46, and the pin body 37 with an outward second annular shoulder 51; the inner diameter of the first annular shoulder 51 is equal to the diameter of the pin body 37 and the inner diameter of the second through hole 49; the outer diameter of the elastic member 47 is equal to the inner diameter of the first through hole 57. It should be noted that the term "equal" is understood to be adapted so that the first annular shoulder 46, the pin body 37 and the second through hole 49 can be reliably assembled, and the elastic member 47 and the first through hole 57 can be reliably assembled. With such a configuration, the pin body 37 can always move linearly without being deflected by being restricted by the inner diameter of the first annular shoulder 46, the diameter of the pin body 37, and the inner diameter of the second through hole 49 during the axial movement of the pin body 37 in the first through hole 57, and the phenomenon of difficulty in return due to the deflection during the movement of the pin body 37 can be avoided.

According to the unlocking method of the lockset provided by the embodiment of the invention, the unlocking position is formed by controlling the unlocking of the lock in the lockset; and then the driving mechanism controls the linkage mechanism to move towards the unlocking position until the linkage mechanism reaches the unlocking position, so that unlocking is realized. Compared with the prior art, according to the unlocking method of the lock provided by the embodiment of the invention, the driving mechanism applies unlocking force to the linkage mechanism, so that the linkage mechanism moves to the unlocking position of the lock to realize unlocking, and the unlocking direction of the lock is from the driving end to the locking end instead of from the locking end to the driving end, so that the formed unlocking mode not only solves the problem that the electronic lock cannot be unlocked by replacing the electronic lock in the prior art, but also enables the structure of the lock to be simpler, the unlocking to be more convenient and the cost to be reduced.
