The anti-pry lock according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 6, an anti-picking lock according to an embodiment of the present invention includes a housing 10, a lock tongue 20, a driving mechanism 30, a backstop mechanism 40 and a control assembly 50. The bolt 20 is slidably mounted on the housing 10; the drive mechanism 30 drives the locking bolt 20 between the locked position and the unlocked position; the retaining mechanism 40 is provided in the housing and can be extended or retracted; the control assembly 50 is used to detect the position of the locking bolt 20 and to control the extension of the retraction mechanism 40 when the locking bolt 20 is disengaged from the locked position to limit movement of the locking bolt 20 to the unlocked position.
Wherein, the lock tongue 20 can be arranged in an arc shape and can be driven to move in the shell 10 by the driving mechanism 30; the bolt 20 can also be arranged in a linear type, so that the driving mechanism 30 drives the bolt 20 to move in a linear manner in the shell 10; specifically, when the lock tongue 20 is in the lock picking state, the retaining mechanism 40 may extend and limit the movement of the lock tongue 20 to the unlocking position, so that the lock tongue 20 cannot be retracted into the housing 10, so that the lock tongue 20 can be kept in the lock-up position, and is prevented from being pried open.
The control assembly 50 may be electrically connected to the locking mechanism 40, and the control assembly 50 may control the locking mechanism 40 to move by detecting the position of the locking bolt 20 and transmitting a signal, so that the locking mechanism 40 can limit the locking bolt 20 to move to the unlocking position.
For example, in the case of installing the anti-prying lock in the embodiment of the present invention on a door, a lock hole corresponding to the anti-prying lock may be provided on a door frame, so that the lock tongue 20 can extend into the lock hole to fix the door, and in the case of using the anti-prying lock provided in the embodiment of the present invention, the door can be fixed, so that, in the case of occurrence of a prying lock, the control component 50 detects the position of the lock tongue 20 and sends a detection signal to the backstop mechanism 40, so that the movement of the lock tongue 20 to the unlocking position can be limited by the backstop mechanism 40, and the lock tongue 20 can be kept connected to the lock hole, so that the lock tongue 20 is prevented from being pried to improve the safety thereof.
Specifically, the retaining mechanism 40 includes a first drive motor 401, a gear 402, and a tooth pin 403, the first drive motor 401 having a motor shaft; the gear 402 is sleeved on the motor shaft to rotate together; the tooth pin 403 has a tooth portion formed thereon to mesh with the gear 402; the first driving motor 401 starts to operate 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 tooth pin 403 to extend.
When the lock picking state occurs, the first driving motor 401 may drive the gear 402 to rotate, so that the gear 402 further drives the tooth pin 403 to extend towards the direction in which the lock tongue 20 moves, thereby restricting the lock tongue 20 from moving to the unlocking position; in other embodiments, the cooperation of the gear 402 and the tooth pin 403 may be adopted, or the tooth pin 403 may be adopted alone to limit the movement of the lock tongue 20 to the unlocking position, for example, the tooth pin 403 may be driven to move to a route where the lock tongue 20 moves to the unlocking position in an electromagnetic manner; accordingly, the detection signal of the control unit 50 controls the tooth pin 403 to extend and restrict the movement of the locking bolt 20 to the unlocking position, so that the locking bolt 20 can be prevented from being opened.
In the embodiment of the present invention, the first driving motor 401, the gear 402 and the tooth pin 403 are jointly embedded in the accommodating groove, wherein the tooth pin 403 is at a predetermined angle with respect to the horizontal direction and can be extended or retracted from the accommodating groove.
Wherein, the accommodating groove is arranged in the shell 10, the first driving motor 401, the gear 402 and the toothed pin 403 can be fixed in the accommodating groove to keep integral stable operation, and the toothed pin 403 is arranged in the accommodating groove, so that the toothed pin 403 can be driven by the first driving motor 401 to extend or retract in the accommodating groove, thereby entering the moving route of the lock tongue 20; specifically, the tooth pin 403 forms a predetermined angle with the horizontal direction, that is, the tooth pin 403 may face the moving path of the lock tongue 20, so that the lock tongue 20 moves toward the unlocking position when picking the lock, and the lock tongue 20 may be restricted.
In a preferred embodiment, the predetermined angle is 40 degrees to 45 degrees. At a predetermined angle of 45 degrees, the tooth pin 403 is perpendicular to the path of movement of the locking bolt 20; when the accommodating portion and the lock tongue 20 are in a linear type, the tooth pin 403 may be perpendicular to or inclined to the moving path of the lock tongue 20, and as will be understood by those skilled in the art, the angle between the tooth pin 403 and the horizontal direction may be set according to the actual requirement, and only the path along which the lock tongue 20 is retracted is limited, so that the lock tongue 20 is kept at the locking position, and the position and angle of the tooth pin 403 may be set arbitrarily, and the preferred position is that the retracted length of the lock tongue 20 is less than one fourth of the length of the lock tongue 20.
Further, a side of the gear 402 opposite to the first driving motor 401 has a cylindrical portion 4022 formed as a whole, and an elastic member 404 is sleeved on the cylindrical portion 4022 and abuts against the accommodating groove to limit movement of the gear 402 in the accommodating groove; wherein the cylindrical portion 4022 is concentric with the gear 402 and has a radius smaller than the radius of the gear 402.
In the embodiment of the present invention, when the gear 402 is driven to rotate by the first driving motor 401, the elastic member 404 and the gear 402 rotate simultaneously, and in general, both the gear 402 and the tooth pin 403 are in a static state, when the tooth pin 403 or the gear 402 moves due to its own weight, the elastic member 404 sleeved on the cylindrical portion 4022 of the gear 402 can form an elastic pushing force in the direction of the first driving motor 401, so as to avoid the movement of the tooth pin 403 or the gear 402.
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 is connected to the lock 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 lock tongue 20 to move to the locking position or the unlocking position. The rotating shaft 302 can rotate around its central axis and drives the rotating rod 301 to drive the lock tongue 20 to rotate together; when the lock tongue 20 is linear, the rotation shaft 302 can drive the lock tongue 20 to move in the linear direction, so that the lock tongue 20 can be driven to an up locking position and an unlocking position.
Specifically, the control assembly 50 is specifically configured to control the extension of the retraction mechanism 40 when the locking bolt 20 is not moved to the unlocked position within a predetermined amount of time after being disengaged from the locked position.
Wherein, the preset time period can be, but is not limited to, 2 seconds, that is, when the prying lock state occurs and the magnetic protrusion does not move to the unlocking position within 2 seconds, the abnormal unlocking is determined and the extension of the retaining mechanism 40 is controlled; it will be appreciated by those skilled in the art that the preset time period may be set according to actual requirements, and is not limited in any way herein.
Further, the control assembly 50 includes a controller 501, and a first switch member 502 and a second switch member 503 connected to the controller 501, where the first switch member 502 and the second switch member 503 have a first state and a second state; the lock tongue 20 or the driving mechanism 30 is provided with a trigger piece 3011, and when the lock tongue 20 rotates to the locking position, the trigger piece 3011 triggers the first switch piece 502 to switch from the first state to the second state; when the lock tongue 20 rotates to the unlocking position, the trigger piece 3011 triggers the second switch piece 503 to switch from the first state to the second state; when the lock tongue 20 is separated from the locking position and does not move to the unlocking position within a predetermined time, the first switch member 502 is restored to the first state, the second switch member 503 is not switched to the second state within a predetermined time, and the controller 501 controls the extension of the backstop mechanism 40.
Wherein the first state is an off 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 with the controller 501, and during normal locking, the rotating shaft 302 drives the rotating rod 301 to rotate, so that the lock tongue 20 rotates to the locking position, the trigger piece 3011 on the rotating rod 301 can be contacted with and conducted with the first switch piece 502, so that the first switch piece 502 enters the second state, and then the controller 501 can detect that the lock tongue 20 is in the locking state; for example, when the anti-picking lock is mounted on the door, the door frame is provided with a lock hole corresponding to the lock tongue 20, and the rotating shaft 302 drives the lock tongue 20 to extend out of the housing 10 and extend into the lock hole through the rotating rod 301 to be locked, so that the first switch 502 and the trigger 3011 are switched from the disconnected state to the connected state.
During normal unlocking, when the rotating shaft 302 drives the rotating rod 301 to rotate, so that the trigger piece 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, from the connection state to the disconnection state, and the controller 501 detects that the first switch piece 502 is in the disconnection state; it will be appreciated that the normal unlocking time may be completed within a predetermined period of time, and thus, when the trigger piece 3011 is disengaged from the first switch piece 502 and is driven to rotate to contact and be turned on with the second switch piece 503 within a predetermined period of time, unlocking is completed, that is, the second switch piece 503 is switched from the off state to the on state with the trigger piece 3011.
Further, when the lock picking occurs, that is, the trigger piece 3011 is separated from the first switch piece 502 and is not in contact with and conducted with the second switch piece 503 within a preset time period, so that the second switch piece 503 is not switched from the off state to the on state within the preset time period, and meanwhile, 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 accommodating groove and limits the movement of the lock tongue 20 to the unlocking position. For example, the preset time period is set to 2 seconds, when the lock is pried, the trigger piece 3011 is separated from the first switch piece 502 for more than 2 seconds and is not connected with the second switch piece 503, the controller 501 can detect that the first switch piece 502 is in an off state, and the second switch piece 503 is also in an off state for more than 2 seconds, so that the controller 501 controls the first driving motor 401 to rotate, and the driving toothed pin 403 limits the movement of the lock tongue 20, so that the lock is prevented from being pried.
The trigger piece 3011 may be disposed on the latch 20 or the driving mechanism 30, so that the trigger piece 3011 can be connected to or disconnected from the first switch piece 502 or the second switch piece 503 at different positions.
Optionally, an alarm device, such as a buzzer, 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 alarms to remind and warn, thereby improving the security 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 being operated by a user 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 rotation shaft 302, and to push the rotation lever 301 to rotate during rotation; wherein, the driving device 305 is connected to the stirring element 304 to drive the stirring element 304 to rotate.
The knob 303 may be disposed outside the housing 10 and fixed relative to the rotation shaft 302 in a circumferential direction, and when in use, the knob 303 may be turned to apply a force to drive the rotation shaft 302 to rotate, so as to drive the rotation shaft 302 to rotate the rotation rod 301, and finally drive the lock tongue 20 to move between the unlocking position and the locking position through the rotation rod 301. The stirring piece 304 is driven by the driving device 305 to rotate relative to the rotating shaft 302 around the central axis of the rotating shaft 302, the stirring piece 304 pushes the rotating rod 301 to rotate in the rotating process, finally the lock tongue 20 is driven to move between the unlocking position and the locking position through the rotating rod 301, the distance between the stirring piece 304 and the central axis of the rotating shaft 302 is smaller than the length of the rotating rod 301, when the stirring piece 304 rotates, the stirring piece 304 abuts against the side face of the rotating rod 301, and the stirring piece 304 can push the rotating rod 301 to rotate along with the continuous rotation of the stirring piece 304.
Further, the driving device 305 includes a second driving motor 3053, a first conical gear 3051, and a second conical gear 3052, where an axis of the first conical 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 driving motor 3053, and is meshed with the first bevel gear 3051; the toggle member 304 is eccentrically disposed on the first conical gear 3051 and extends along an up-down direction, an axis of the first conical gear 3051 extends along the up-down direction, an axis of the second conical gear 3052 extends along a horizontal direction, that is, the axes of the first conical gear 3051 and the second conical gear 3052 are vertically arranged relatively, the second driving motor 3053 is connected with the second conical gear 3052, and therefore the second conical gear 3052 is driven to rotate through the second driving motor 3053, the first conical gear 3051 and the second conical gear 3052 are enabled to synchronously rotate and drive the rotating shaft 302 and the toggle member 304, and the structure is safer and more stable.
