Anti-theft lock with modular drive device

Abstract

The invention discloses an anti-theft lock with a modular drive device. The anti-theft lock comprises a lock body and a driving module. A spring bolt and a transmission device are arranged in the lockbody. The transmission device is connected with the spring bolt. The driving module comprises a driving box body and a driving mechanism. The driving box body is arranged in the lock body. A notch isformed in the side, close to the transmission device, of the driving box body. The driving mechanism is fixed in the driving box body. One end of the driving mechanism is exposed in the notch and islinked with the transmission device, so that the driving device drives the transmission device to eject the spring bolt out of the lock body or withdraw the spring bolt into the lock body. According to the anti-theft lock with the modular drive device, a plurality of gears in the driving device are arranged in the box body connected with the lock body, when the gears in the driving device need tobe replaced, only the whole box body needs to be detached from the lock body, the replacement action can be completed by replacing the box body with a new box body internally provided with driving gears, the situation that gears are scattered and fall off is avoided, the maintenance efficiency of the lock body is improved, and the stability and reliability of the lock body can be improved.

Description

technical field [0001] The invention relates to the field of door locks, in particular to an anti-theft lock with a modular driving device. Background technique [0002] At present, anti-theft locks are widely used in various occasions due to their high security. Existing anti-theft locks are provided with driving devices, such as several gears installed in the lock body, through which the gears rotate in cooperation with each other to push the closing of the mechanical switch in the lock body to complete the unlocking and locking actions. [0003] And the most easily damaged part in the existing anti-theft lock body is the drive device therein. Because several gears in the lock body are generally fixed on the shell plate of the lock body by rotating shafts, and each gear is meshed with each other. Cooperate with each other and rotate, if a gear in the lock body is abnormal, it will cause the linkage of the entire driving device, affecting the normal operation of each struc...

Problems solved by technology

[0003] And the most easily damaged part in the existing anti-theft lock body is the drive device therein. Because several gears in the lock body are generally fixed on the shell plate of the lock body by rotating shafts, and each gear is meshed with each other. Cooperate with each other to rotate, if a gear in the lock body is abnormal, it will lead to the linkage of the entire driving device, affecting the normal operation of each structure in the lock body

[0004] If you want to replace one of the gears, first, you need to disassemble the shell plate of the lock body, but at this time, the gears connected to the shell plate are prone to drop; afterwards, due to the tight fit between the gears, if To replace a certain gear, it is necessary to remove all the gears linked with the gear from the shell plate of the lock body. After the gears are replaced, the several gears are spliced ​​back into the lock body. The whole replacement process is complicated and time consuming. It takes a long time to improve the maintenance efficiency, and the scattered gear parts are easy to lose when they are removed. After replacing the new gears, there may be adjacent gears that cannot mesh perfectly, resulting in poor stability of the lock body.
