Anti-theft lock

Abstract

The invention relates to an anti-theft lock, which can be used for effectively solving the problems of complicated structure and poor anti-theft effect of a pin tumbler lock. The technical scheme adopted by the invention is as follows: the anti-theft lock comprises a lock body and a lock core, the lock core is mounted in the center of the lock body, a moving ball braking hole is formed in the internal wall of the lower part of the lock body, first moving ball holes are formed in the center of the lock core in the transverse direction, second moving ball holes communicated with the first moving ball holes are formed in the lower part of the lock core, the center line of the first moving ball holes is vertical to that of the second moving ball holes, a keyhole, which is located above the first moving ball holes and is communicated with the first moving ball holes, is formed in the upper part of the lock core, first moving balls, which can move leftwards and rightwards, are mounted in the first moving ball holes, a cylindrical bulged part, which extends into the keyhole, is arranged at the upper part of each first moving ball hole, the lower part of each first moving ball hole is provided with a plurality of clamping grooves, and second moving balls, which can move upwards and downwards, are mounted in the second moving ball holes. The anti-theft lock has the advantages of novel, unique and simple structure, easiness in operation, strong anti-theft function and low cost, and accordingly has excellent social and economic benefits.

Description

technical field [0001] The invention relates to a lock, in particular to an anti-theft lock. Background technique [0002] Locks are common anti-theft tools. The tumbler lock is widely used because of its simple structure and practicality. The structure of the pin lock is roughly the same, that is, a group of cylindrical pins are installed in the pin hole of the lock cylinder, and the key has a corresponding depth of teeth. The method of unlocking is roughly the same, that is, move the corresponding pins up and down according to the different heights of the key teeth, so that the height of each lock pin pin is at the interface between the lock shell and the lock core, and then rotate the key to drive the lock. Core, to achieve the purpose of unlocking. This type of lock is located in the shifting tooth channel. Without touching the pin, foreign matter can easily enter the inner end of the keyhole, and various unlocking tools can be inserted through the shifting tooth chan...
