The anti-picking lock according to the embodiment of the invention is described in detail with reference to the attached drawings.

Referring to fig. 1 to 6, an anti-picking lock according to an embodiment of the present invention includes a housing 10, a bolt 20, a driving mechanism 30, a retaining mechanism 40, and a control assembly 50. Locking bolt 20 is slidably on housing 10; actuating mechanism 30 actuates movement of locking bolt 20 between the unlocked and locked positions; the retaining mechanism 40 is arranged in the lock shell and can extend out or retract; control assembly 50 is configured to detect the position of locking bolt 20 and to inhibit extension of reversing mechanism 40 to limit movement of locking bolt 20 to the unlocked position when locking bolt 20 is out of the locked position.

Wherein, the locking bolt 20 can be arranged in an arc shape and can be driven by the driving mechanism 30 to move in the housing 10; the latch bolt 20 may be arranged in a linear type, so that the driving mechanism 30 drives the latch bolt 20 to move linearly in the housing 10; specifically, when bolt 20 is in a picking state, backstop mechanism 40 may extend and restrict movement of bolt 20 to an unlocked position, such that bolt 20 cannot be retracted into housing 10, such that it can remain in a locked position, and thus be prevented from being pried open.

Wherein, control assembly 50 can be with stopping mechanism 40 electric connection, and control assembly 50 can control stopping mechanism 40 through the position that detects spring bolt 20 and transmission signal and move to make stopping mechanism 40 can restrict spring bolt 20 and move to the unblock position.

For example, the anti-prying lock provided by the embodiment of the invention can be installed on a door, a lock hole corresponding to the anti-prying lock can be arranged on a door frame, so that the lock tongue 20 can extend into the lock hole to fix the door, and the anti-prying lock provided by the embodiment of the invention can fix the door, so that the control assembly 50 detects the position of the lock tongue 20 and sends a detection signal to the stopping mechanism 40 under the condition of lock prying, so that the stopping mechanism 40 can limit the lock tongue 20 to move to the unlocking position, the lock tongue 20 can be kept connected with the lock hole, and thus, the lock tongue is prevented from being pried open to improve the safety of the lock tongue 20.

Specifically, the retaining mechanism 40 includes a first driving motor 401, a gear 402, and a tooth pin 403, the first driving motor 401 having a motor shaft; the gear 402 is sleeved on the motor shaft to rotate together; a tooth portion that meshes with the gear 402 is formed on the tooth pin 403; the first driving motor 401 is started under the control of the control assembly 50, and drives the gear 402 to rotate through the motor shaft, so that the gear 402 drives the gear pin 403 to extend.

When a lock picking state occurs, the first driving motor 401 may drive the gear 402 to rotate, so that the gear 402 further drives the toothed pin 403 to extend toward the direction of movement of the lock tongue 20, so that the gear limits the lock tongue 20 to move to the unlocking position; in other embodiments, the gear 402 and the toothed pin 403 may be used in cooperation, or the toothed pin 403 may be used alone to limit the movement of the latch bolt 20 to the unlocking position, for example, the toothed pin 403 may be electromagnetically driven to move to the route of the latch bolt 20 to the unlocking position; therefore, the detection signal of the control assembly 50 controls the tooth pin 403 to extend and restrict the movement of the latch bolt 20 to the unlock position, so that the latch bolt 20 can be prevented from being opened.

In the embodiment of the present invention, the present invention further includes a receiving groove 101, and the first driving motor 401, the gear 402 and the tooth pin 403 are jointly embedded in the receiving groove 101, wherein the tooth pin 403 is at a predetermined angle with respect to the horizontal direction and can extend out of or retract into the receiving groove 101.

Wherein, the accommodating groove 101 is arranged in the housing 10, the first driving motor 401, the gear 402 and the tooth pin 403 can be fixed in the accommodating groove 101 to keep the stable operation of the whole, the tooth pin 403 is arranged in the accommodating groove 101, so that the tooth pin 403 can be driven by the first driving motor 401 to extend or retract in the accommodating groove 101, thereby entering the moving route of the bolt 20; specifically, toothed pin 403 is at a predetermined angle with respect to the horizontal direction, that is, toothed pin 403 may be aligned with the movement path of locking bolt 20, so that locking bolt 20 may move toward the unlocking position during picking the lock, and locking bolt 20 may be restricted.

In a preferred embodiment, the predetermined angle is 40-45 degrees. When the predetermined angle is 45 degrees, the toothed pin 403 is perpendicular to the path of the movement of the locking bolt 20; when the receiving portion and the locking tongue 20 are linear, the tooth pin 403 may also be disposed perpendicular to or obliquely to the movement path of the locking tongue 20, and it can be understood by those skilled in the art that the angle between the tooth pin 403 and the horizontal direction may be set according to actual requirements, only the retraction path of the locking tongue 20 needs to be limited, so that the locking tongue 20 is kept at the locking position, the position and the angle of the tooth pin 403 may be set arbitrarily, and the preferred position is that the retraction length of the locking tongue 20 is less than one fourth of the length of the locking tongue 20 itself.

Further, one side of the gear 402 opposite to the first driving motor 401 has a pillar 4022 formed as a whole, and the pillar 4022 is sleeved with an elastic element 404 and abuts against the receiving groove 101 to limit the movement of the gear 402 in the receiving groove 101; wherein the post 4022 is concentric with the gear 402 and has a radius less than the radius of the gear 402.

In the embodiment of the present invention, when the gear 402 is driven by the first driving motor 401 to rotate, the elastic member 404 and the gear 402 rotate simultaneously, generally, the gear 402 and the tooth pin 403 are both in a stationary state, and when the tooth pin 403 or the gear 402 moves due to its own gravity, the elastic member 404 sleeved on the cylindrical portion 4022 of the gear 402 may form an elastic pushing force toward the first driving motor 401, so as to prevent the tooth pin 403 or the gear 402 from moving.

Specifically, the driving mechanism 30 includes a rotating shaft 302 and a rotating rod 301, one end of the rotating rod 301 is connected to the rotating shaft 302, the other end of the rotating rod 301 is connected to the locking tongue 20, and the rotating shaft 302 is used for driving the rotating rod 301 to rotate, so that the rotating rod 301 drives the locking tongue 20 to move to the locking position or the unlocking position. The rotating shaft 302 can rotate around the central axis of the rotating shaft, and drives the rotating rod 301 to drive the bolt 20 to rotate together; when the latch bolt 20 is linear, the rotating shaft 302 can drive the latch bolt 20 to move in a linear direction, so that the latch bolt 20 can be driven to the locked position and the unlocked position.

Specifically, control assembly 50 is specifically configured to control extension of backstop mechanism 40 when locking bolt 20 has not moved to the unlocked position within a predetermined time after being released from the locked position.

The preset time period may be, but is not limited to, 2 seconds, that is, when a lock picking state occurs and the magnetic protrusion does not move to the unlocking position within 2 seconds, it is determined that the lock is abnormally unlocked and the retaining mechanism 40 is controlled to extend out; it can be understood by those skilled in the art that the preset time period can be set according to actual requirements, and is not limited in any way.

Further, the control assembly 50 includes a controller 501, and a first switch 502 and a second switch 503 connected to the controller 501, wherein the first switch 502 and the second switch 503 have a first state and a second state; the trigger 3011 is disposed on the locking tongue 20 or the driving mechanism 30, and when the locking tongue 20 rotates to the locked position, the trigger 3011 triggers the first switch 502 to switch from the first state to the second state; when the locking bolt 20 rotates to the unlocking position, the trigger 3011 triggers the second switch 503 to switch from the first state to the second state; when the locking bolt 20 is out of the locked position and is not moved to the unlocked position within the predetermined time, the first switch member 502 is restored to the first state, and the second switch member 503 is not switched to the second state within the predetermined time, and the controller 501 controls the anti-backup mechanism 40 to extend.

Wherein the first state is a disconnected state and the second state is a connected state; the first switch piece 502, the second switch piece 503 and the first driving motor 401 are all electrically connected to the controller 501, when the lock is normally closed, the rotating shaft 302 drives the rotating rod 301 to rotate, so that the lock tongue 20 rotates to the locking position, the trigger 3011 on the rotating rod 301 can contact and be conducted with the first switch piece 502, so that the first switch piece 502 enters the second state, and at this time, the controller 501 can detect that the lock tongue 20 is in the locking state; for example, when the anti-prying lock is installed on a door, a lock hole corresponding to the lock tongue 20 is formed in a door frame, and the rotating shaft 302 drives the lock tongue 20 to extend out of the housing 10 and into the lock hole through the rotating rod 301 to be locked, so that the first switch member 502 and the trigger 3011 are switched from a disconnected state to a connected state.

When the lock is normally unlocked, when the rotating shaft 302 drives the rotating rod 301 to rotate, so that the trigger 3011 is separated from the first switch piece 502, the first switch piece 502 is switched from the second state to the first state, that is, switched from the connected state to the disconnected state, and the controller 501 detects that the first switch piece 502 is in the disconnected state; it can be understood that the normal unlocking time can be completed within a preset time period, and therefore, the triggering piece 3011 is disengaged from the first switch piece 502 and is driven to rotate to contact and conduct with the second switch piece 503 within the preset time period, so as to complete the unlocking, that is, the second switch piece 503 and the triggering piece 3011 are switched from the off state to the connected state.

Further, when the lock picking occurs, that is, the triggering piece 3011 is disengaged from the first switch piece 502 and is not in contact with the second switch piece 503 for a preset time period, so that the second switch piece 503 is not switched from the off state to the on state for the preset time period, and at the same time, the controller 501 controls the first driving motor 401 to rotate due to the fact that the second switch piece 503 is in the off state, so that the tooth pin 403 extends out of the receiving groove 101 and the movement of the lock tongue 20 to the unlocking position is limited. For example, the preset time period is set to 2 seconds, when the lock picking occurs, the trigger 3011 is separated from the first switch 502 for more than 2 seconds and is not connected to the second switch 503, the controller 501 can detect that the first switch 502 is in the off state, and the second switch 503 is also in the off state for more than 2 seconds, so that the controller 501 controls the first driving motor 401 to rotate, so that the driving toothed pin 403 limits the movement of the lock tongue 20 to avoid being picked.

The trigger 3011 may be disposed on the tongue 20 or the driving mechanism 30, so that the trigger 3011 can be connected to or disconnected from the first switch 502 or the second switch 503 at different positions.

Optionally, an alarm device, such as a buzzer or the like, may be disposed on the controller 501, and when the detection signal is in a lock picking state, the detection signal may be sent to the alarm device, so that the alarm device gives an alarm to remind and warn, thereby improving the safety of the alarm device.

Specifically, the device further comprises a knob 303, a toggle member 304 and a driving device 305, wherein the knob 303 is connected with the rotating shaft 302 for a user to operate to push the rotating rod 301 to rotate; the toggle member 304 is configured to be rotatable about the central axis with respect to the rotating shaft 302, and pushes the rotating lever 301 to rotate during rotation; the driving device 305 is connected to the toggle member 304 to drive the toggle member 304 to rotate.

The knob 303 may be disposed outside the housing 10 and circumferentially fixed relative to the rotating shaft 302, and when in use, the knob 303 may be rotated to apply an acting force to drive the rotating shaft 302 to rotate, and then the rotating shaft 302 drives the rotating rod 301 to rotate, and finally the rotating rod 301 drives the locking tongue 20 to move between the unlocking position and the locking position. The toggle member 304 is driven by the driving device 305 to rotate around the central axis of the rotating shaft 302 relative to the rotating shaft 302, and the toggle member 304 pushes the rotating rod 301 to rotate in the rotating process, and finally the bolt 20 is driven to move between the unlocking position and the locking position by the rotating rod 301, and the distance between the toggle member 304 and the central axis of the rotating shaft 302 is smaller than the length of the rotating rod 301, when the toggle member 304 rotates, the toggle member 304 abuts against the side surface of the rotating rod 301, and along with the continuous rotation of the toggle member 304, the toggle member 304 can push the rotating rod 301 to rotate.

Further, the driving device 305 includes a second driving motor 3053, a first bevel gear 3051 and a second bevel gear 3052, and an axis of the first bevel gear 3051 coincides with an axis of the rotating shaft 302; the second bevel gear 3052 is connected to an output shaft of the second drive motor 3053 and is engaged with the first bevel gear 3051; the stirring piece 304 is eccentrically arranged on the first conical gear 3051 and extends in the vertical direction, the axis of the first conical gear 3051 extends in the vertical direction, the axis of the second conical gear 3052 extends in the horizontal direction, that is, the axes of the first conical gear 3051 and the second conical gear 3052 are relatively vertically arranged, the second driving motor 3053 is connected with the second conical gear 3052, so that the second conical gear 3052 is driven by the second driving motor 3053 to rotate, the first conical gear 3051 and the second conical gear 3052 synchronously rotate and drive the rotating shaft 302 and the stirring piece 304, and the structure is safer and more stable.
