Anti-theft tumbler lock

Abstract

The invention discloses an anti-theft ball lock and mainly relates to the fields of locks. The anti-theft ball lock comprises a lock housing, wherein a lock cylinder is arranged in the lock housing and is provided with a first key insertion groove, the lock cylinder is provided with a first ball hole, the lock housing is provided with a second ball hole, a first ball group is arranged between the first ball hole and the second ball hole and comprises a first ball and a second ball, the lock cylinder is provided with a second key insertion groove and a third ball hole, the lock housing is provided with a fourth ball hole, a second ball group is arranged between the third ball hole and the fourth ball hole and comprises a third ball and a fourth ball, and the lock housing is provided with connecting grooves communicated with the second ball hole and the fourth ball hole and elastic linkage parts arranged in the connecting grooves and connected with the second ball hole and the fourth ball hole. The anti-theft ball lock is provided with the two ball groups, the elastic linkage parts making the corresponding ball groups linked mutually are arranged between the corresponding ball groups to prevent technical lock opening, and the thievery prevention performance of the lock is improved.

Description

【Technical field】 [0001] The application relates to the field of locks, in particular to an anti-theft tumbler lock. 【Background technique】 [0002] A traditional pin lock is mainly composed of a lock case, a rotatable lock cylinder, and several rows of pins. Taking the most common anti-theft lock with cylindrical pins as an example, after inserting the correct key, the pins in each row are in the correct position, that is, the lower pins are just in the lock cylinder, and the upper pins are just in the lock shell, so that the lock shell can be rotated and thus Unlock the lock; if the key is pulled out or the wrong key is inserted, the marble will be between the lock shell and the lock cylinder so that the lock cylinder cannot rotate. The disadvantage of the traditional pin lock is that you can apply torque to the lock cylinder with the help of tools to make the pin bear an appropriate cross-cutting force, use the force sense to try and dial, and separate the upper pin and ...

Problems solved by technology

The disadvantage of the traditional pin lock is that you can apply torque to the lock cylinder with the help of tools to make the pin bear an appropriate transverse force, and use the force sense to try and dial, and separate the upper pin and the lower pin into the holes of the lock shell and the lock cylinder one by one, so as to realize technology on
