Description

Technical Field

[0001] This invention relates to the field of gun trigger lock technology, and more particularly to a gun trigger lock. Background Technology

[0002] Firearms generally need to be stored discreetly, locked in gun cabinets, safes, or using traditional keys and digital combination locks to lock the triggers. However, these methods are slow to unlock and react. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a gun trigger lock to solve the problem of slow unlocking time.

[0004] To achieve the above objectives, the present invention provides a gun trigger lock, comprising a housing, the housing including an upper shell with a receiving groove and a lower shell that mates with the upper shell, a fingerprint recognition button and an indicator light being disposed on the outside of the upper shell, a circuit board being disposed within the receiving groove and connected to both the fingerprint recognition button and the indicator light, a motor being disposed on one side of the circuit board and electrically connected to the circuit board, a cam being connected to the output end of the motor, a first mating inclined surface being provided on the protruding end of the cam, an inner cover plate being installed within the receiving groove of the upper shell, and a first opening being provided on the side of the inner cover plate facing the lower shell. The inner cover plate has a first slot in which a locking hook connected to the lower shell is installed. A second slot communicating with the first slot is provided on the other side of the inner cover plate. A locking hook side slot is provided on the side wall of the locking hook facing the second slot. A locking tongue is slidably disposed in the second slot. One end of the locking tongue is provided with a locking tongue that cooperates with the locking hook side slot. The other end of the locking tongue is connected to the second slot through a locking tongue spring. A vertical push plate is provided on the side of the locking tongue away from the lower shell. A second mating slope is provided on the vertical push plate that cooperates with the first mating slope. The motor drives the cam to rotate, and the first mating inclined surface on the cam abuts against the second mating inclined surface on the vertical push plate, causing the locking tongue to move away from the locking hook side slot, so that the locking tongue disengages from the locking hook side slot, realizing the separation of the upper shell and the lower shell, and is used to open the trigger lock.

[0005] Optionally, the bottom of the receiving groove is connected to a lock hook push rod via a lock hook push rod spring. The bottom of the first slot has a through hole for the lock hook push rod to pass through. The through hole is located below the lock hook side slot. After the lock tongue disengages from the lock hook side slot, the lock hook push rod extends under the elastic action of the lock hook push rod spring to push the lock hook to move, thereby realizing the automatic separation of the upper shell and the lower shell.

[0006] Optionally, a lock cylinder assembly extending into the receiving groove is installed on the side wall of the upper shell, a key that cooperates with the lock cylinder assembly is provided outside the shell, an arc-shaped ramp boss located in the receiving groove is provided at the end of the lock cylinder assembly, a lock tongue push block is slidably provided on the arc-shaped ramp boss, the other end of the lock tongue push block abuts against the vertical push plate, and an inclined guide wall that is slidably connected to the lock tongue push block is provided on the inner cover plate; When the key is inserted into the lock cylinder assembly and rotated, the arc-shaped ramp boss rotates simultaneously, pushing the lock tongue pusher block to move towards the vertical push plate. This pushes the vertical push plate to compress the lock tongue spring, causing the lock tongue to move away from the lock hook side slot. This allows the lock tongue to disengage from the lock hook side slot, achieving the separation of the upper and lower shells, which is used to open the gun trigger lock.

[0007] Optionally, the inclined guide wall is provided with an inclined rail that is slidably connected to the latch push block, and an inclined slider that is fixedly connected to the latch push block is slidably connected to the inclined rail. The arc-shaped ramp is provided with an arc-shaped guide rail that is slidably connected to the latch push block, and an arc-shaped slider that is fixedly connected to the latch push block is slidably connected to the arc-shaped guide rail. The latch push block is located on the side of the inner cover plate facing the bottom of the receiving groove.

[0008] Optionally, a lower adhesive pad is provided between the inner cover plate and the lower shell, and an upper adhesive pad is provided between the inner cover plate and the bottom of the inner casing groove of the upper shell.

[0009] Optionally, a battery is electrically connected to one side of the circuit board, a buffer pad is provided between the battery and the circuit board, and the battery is located between the circuit board and the inner cover plate.

[0010] The beneficial effects of this invention are as follows: This invention provides a gun trigger lock. Under normal circumstances, the user uses their fingerprint, which is set in the fingerprint module on the circuit board, to open the lock. In the locked state, the cam's support rod faces downwards and does not contact the latch, as shown in the figure. In the locked state, the latch tongue extends into the latch side groove of the hook, preventing the hook from being pulled out. This connects the upper and lower shells of the lock, preventing the locked object between them from detaching, thus achieving the locking function. In the unlocking state, after successful fingerprint recognition, the motor starts, driving the cam to rotate. The first mating inclined surface on the cam abuts against the second mating inclined surface on the vertical push plate, causing the latch to move away from the latch side groove, thus separating the upper and lower shells and opening the gun trigger lock. After unlocking, the cam rotates back to its starting position. Attached Figure Description

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0016] like Figures 1 to 17As shown, a gun trigger lock includes a housing, which includes an upper shell 18 with a receiving groove and a lower shell 1 that mates with the upper shell 18. A fingerprint recognition button 23 and an indicator light 24 are provided on the outside of the upper shell 18. A circuit board 16, connected to both the fingerprint recognition button 23 and the indicator light 24, is disposed within the receiving groove. A motor 13, electrically connected to the circuit board 16, is disposed on one side of the circuit board 16. A cam 12 is connected to the output end of the motor 13, and a first mating inclined surface 28 is provided on the protruding end of the cam 12. An inner cover plate 21 is screwed into the receiving groove of the upper shell 18. The circuit board 16 and the motor 13 are located between the inner cover plate 21 and the bottom of the receiving groove. The inner cover plate 21 and the lower shell 1... A first slot 30 is provided on one side facing each other. A locking hook 3 connected to the lower shell 1 is installed in the first slot 30. A second slot 31 communicating with the first slot 30 is provided on the other side of the inner cover plate 21. A locking hook side groove 25 is provided on the side wall of the locking hook 3 facing the second slot 31. A locking tongue 8 is slidably arranged in the second slot 31. One end of the locking tongue 8 is provided with a locking tongue 26 that cooperates with the locking hook side groove 25. The other end of the locking tongue 8 is connected to the second slot 31 through a locking tongue spring 9. A vertical push plate 27 is provided on the side of the locking tongue 8 away from the lower shell 1. A second mating slope 29 that cooperates with the first mating slope 28 is provided on the vertical push plate 27. The motor 13 drives the cam 12 to rotate. The first mating inclined surface 28 on the cam 12 abuts against the second mating inclined surface 29 on the vertical push plate 27, causing the locking tongue 8 to move away from the locking hook side slot 25, so that the locking tongue 26 disengages from the locking hook side slot 25, realizing the separation of the upper shell 18 and the lower shell 1, which is used to open the gun trigger lock.

[0017] Under normal circumstances, the user uses their fingerprint, which is set in the fingerprint module on the circuit board 16, to open the lock. In the locked state, the support rod of the cam 12 faces downward and does not contact the latch 8. Figure 12 As shown, in the locked state, the locking tongue 26 of the locking tongue 8 extends into the locking hook side slot 25 of the locking hook 3, so that the locking hook 3 cannot be pulled out, realizing the connection between the upper shell 18 and the lower shell 1 of the lock. The locked object located between the upper shell 18 and the lower shell 1 cannot be dislodged, thus realizing the locking function. When the lock is in the unlocked state, after successful fingerprint recognition, the motor 13 starts and drives the cam 12 to rotate. The first mating inclined surface 28 on the cam 12 abuts against the second mating inclined surface 29 on the vertical push plate 27, causing the lock tongue 8 to move away from the lock hook side slot 25, so that the lock tongue 26 disengages from the lock hook side slot 25, realizing the separation of the upper shell 18 and the lower shell 1, which is used to open the gun trigger lock. After the unlock is completed, the cam 12 rotates back to the starting position.

[0018] like Figures 10 to 11 As shown, the bottom of the receiving groove is connected to a lock hook push rod 10 via a lock hook push rod spring 11. The bottom of the first slot 30 has a through hole 32 for the lock hook push rod 10 to pass through. The through hole 32 is located below the lock hook side slot 25. After the lock tongue 26 disengages from the lock hook side slot 25, the lock hook push rod 10 extends under the elastic action of the lock hook push rod spring 11, pushing the lock hook 3 to move, thus achieving automatic separation of the upper shell 18 and the lower shell 1. Furthermore, the extended lock hook push rod 10 blocks the movement of the lock tongue 8, preventing the lock tongue 8 from affecting the movement of the lock hook 3. Figure 10 As shown, in the unlocked state, the lock hook 3 does not contact the lock hook push rod 10, and the lock hook push rod spring 11 is in a relaxed state, causing the lock hook push rod 10 to move upward. One end of the lock hook push rod 10, with its columnar feature, abuts against the end face of the lock tongue 8, thus limiting the lock tongue 8 and preventing it from extending outward. Figure 11 As shown, when the upper shell 18 and the lower shell 1 are closed, the locking hook 3 is pressed downwards, and its end abuts against the columnar feature end face of the locking hook push rod 10, causing it to press downwards. The locking hook 3 is pressed to the bottom, and the restriction of the columnar feature on the locking hook push rod 10 on the locking tongue 26 at the end of the locking tongue 8 is removed. The locking tongue 8 extends outwards under the pushing force of the locking tongue spring 9, and the end of the locking tongue 8 is inserted into the locking hook side groove 25 of the locking hook 3, which plays the role of locking the locking hook 3.

[0019] like Figures 1 to 4 , Figures 16 to 17 As shown, a lock cylinder assembly 5 extending into the receiving groove is installed on the side wall of the upper shell 18. A key 4 that cooperates with the lock cylinder assembly 5 is provided outside the shell. The lock cylinder assembly 5 is located between the inner cover plate 21 and the bottom of the receiving groove. An arc-shaped ramp boss 33 located in the receiving groove is provided at the end of the lock cylinder assembly 5. A lock tongue push block 7 is slidably provided on the arc-shaped ramp boss 33. The other end of the lock tongue push block 7 abuts against the vertical push plate 27. An inclined guide wall that is slidably connected to the lock tongue push block 7 is provided on the inner cover plate 21. When the key 4 is inserted into the lock cylinder assembly 5 and rotated, the arc-shaped ramp boss 33 rotates simultaneously, pushing the lock tongue push block 7 to move towards the vertical push plate 27, pushing the vertical push plate 27 to squeeze the lock tongue spring 9, causing the lock tongue 8 to move away from the lock hook side slot 25, so that the lock tongue 26 disengages from the lock hook side slot 25, realizing the separation of the upper shell 18 and the lower shell 1, which is used to open the gun trigger lock.

[0020] The lock cylinder assembly 5 is provided with a torsion spring 6 located in the arc-shaped ramp boss 33 at its end. The two ends of the torsion spring 6 are respectively connected to the lock cylinder assembly 5 and the upper shell 18. After unlocking, when the key 4 is released, the lock cylinder assembly 5 is reset under the action of the torsion spring 6. The bolt push block 7 also contacts the lowest point of the arc-shaped ramp boss 33 at the tail of the lock cylinder assembly 5. The torsion spring 6 can automatically rotate the lock cylinder assembly 5 back to its original position, preventing the user from forgetting to rotate the lock cylinder assembly 5 and thus being unable to lock it.

[0021] The inclined guide wall is provided with an inclined rail that is slidably connected to the latch push block 7. An inclined slider that is fixedly connected to the latch push block 7 is slidably connected to the inclined rail. The arc-shaped inclined boss 33 is provided with an arc-shaped guide rail that is slidably connected to the latch push block 7. An arc-shaped slider that is fixedly connected to the latch push block 7 is slidably connected to the arc-shaped guide rail. The latch push block 7 is located on the side of the inner cover plate 21 facing the bottom of the receiving groove. When the arc-shaped inclined boss 33 rotates, the arc-shaped inclined boss 33 pushes the latch push block 7 to move along the inclined rail and pushes the vertical push plate 27, causing the latch 8 to move away from the lock hook side slot 25, so that the latch 26 disengages from the lock hook side slot 25.

[0022] A lower rubber pad 2 is provided between the inner cover plate 21 and the lower shell 1, and an upper rubber pad 22 is provided between the inner cover plate 21 and the bottom of the inner storage groove of the upper shell 18. The lower rubber pad 2 and the upper rubber pad 22 serve as protection and cushioning.

[0023] A battery 14 is electrically connected to one side of the circuit board 16. A buffer pad 15 is provided between the battery 14 and the circuit board 16 to cushion and protect the circuit board 16. The battery 14 is located between the circuit board 16 and the inner cover plate 21. Electronic components such as a fingerprint module, USB interface, battery 14 interface, and motor 13 interface are installed on the circuit board 16. It is the core component of the fingerprint lock and plays a role in receiving and recognizing fingerprint information, operating the circuit, controlling the warning light, and controlling the power. The buffer pad 15 protects the circuit board 16 from the squeezing and impact of the parts installed on the upper part of the circuit board 16.

[0024] The upper shell 18 is provided with a silicone sealing gasket 17 that cooperates with the fingerprint recognition button 23. The upper shell 18 is provided with a protective cover 19 for protecting the lock cylinder assembly 5. The upper shell 18 is provided with a charging port that is connected to the circuit board 16. A USB interface silicone plug 20 is provided at the charging port.

[0025] After fingerprint registration, if the fingerprint is correctly recognized, indicator light 24 will be green, and the lock can be opened; if the fingerprint is incorrectly recognized, indicator light 24 will be red, and the lock cannot be opened.

[0026] When the battery is low, indicator light 24 flashes intermittently, prompting the user to charge battery 14.
