Gun trigger lock

Abstract

The invention discloses a gun trigger lock which comprises a lock body and a locking cover capable of being turned over relative to the lock body. The lock body is provided with an identity recognition device, a control circuit board, a drive device, a locking mechanism and a power source module. The identity recognition device is used for acquiring user identity information and sending the user identity information to the control circuit board. The control circuit board controls the drive device to act according to the comparison result of the identity information. The drive device drives the locking mechanism to act. The power module supplies power to the identity recognition device, the control circuit board and the drive device. The lock cover is provided with a buckle plate bucked to the locking mechanism. The gun trigger lock drops out when opened and is convenient to operate. A miniature worm and gear motor is adopted to drive the locking mechanism and is small in size, low in output power and beneficial to lightweight and miniaturization of the gun trigger lock. The gun trigger lock is further provided with a mechanical emergency unlocking mechanism. The gun trigger lock can be unlocked through the mechanical emergency unlocking mechanism under the emergency condition. A fingerprint unlocking manner, a sound unlocking manner, an RFID unlocking manner, a Bluetooth unlocking manner and the like can be selected and used for the identity recognition device.

Description

technical field [0001] The invention relates to the technical field of firearm locks, in particular to a firearm trigger lock. Background technique [0002] Guns are controlled weapons and have serious lethality. They need to be kept strictly and cannot be used by unauthorized people, otherwise troubles will arise. If the gun does not have a safety lock, it is easy to misuse the trigger and cause a fire, or it will be used illegally by others, which will cause serious consequences. The gun safety lock can lock the trigger part of the gun so that it cannot be used casually. [0003] See Chinese patent CN104034203A, which discloses an intelligent safety lock for firearms. The structure of the safety lock mainly includes a left lock seat and a right lock seat which are interlocked. At the trigger position, a control circuit board, a locking mechanism and a motor are arranged inside the right lock seat, and a fingerprint acquisition board is arranged on the housing of the right...

AI Technical Summary

Problems solved by technology

Compared with the traditional mechanical gun lock, the gun smart safety lock uses fingerprint recognition to open the safety lock, which improves the safety of gun use and is easy to operate. There are still some urgent technical problems that need to be solved, and these problems may have a serious impact on actual use

For example, when the safety lock is opened, the left lock seat and the right lock seat cannot be separated automatically, and can only be separated from each other manually, which brings inconvenience to the unlocking operation of the gun; the safety lock uses a motor to directly drive the locking mechanism to act , which has high requirements on the motor and battery, and it needs a motor with a large output power to be able to realize it; the fingerprint recognition starts in a relatively simple way, such as a battery shortage or a mechanical structure failure, which may cause the problem that the safety lock cannot be opened or locked
