Cylindrical type anti-theft lock

Abstract

The invention relates to a kind of theft-proof lock with cylinder type. Its main characteristic is that there are at least two scoop channels which are established in the radial with the circumference of lock core, and on the stated scoop channel locate some pylomes that are linked to the lock hole. The lock slice channel of the lock core. The directing pillar on the stated lock slice that is equipped with scoop channels cut through the pylome of the radial scoop channels on the lock core that is also equipped with scoop channels along its periphery axis. The latter scoop channels is less than the scoop channels on the radial scoop channel of the lock core in depth, while matches with the scoop channels on the lock slice. On the flange of the two stated radial circumference and in the scoop channels along the lock core's axis locates springs, which in the scoop channels along the lock core's axis establishes overarm. The invention's design is novel and has good theft-proof performance, so it is certain to bring positive effect to the consumers.

Description

【Technical field】 [0001] The invention relates to an anti-theft lockset, in particular to a cylindrical anti-theft lockset. 【Background technique】 [0002] At present, there are many kinds of locks on the market, with different structures and various performances.

The anti-theft lock of this structure has relatively good anti-theft performance, but it is very troublesome to arrange a fully ...

AI Technical Summary

Problems solved by technology

The anti-theft lock of this structure has relatively good anti-theft performance, but it is very troublesome to arrange a fully connected piece lock cylinder hole on the lock cylinder. Due to its complicated process, the production efficiency of the lock cylinder will be reduced. reduce

And the flat keyhole must use a flat key, and this flat key also has a guide groove on the key blade to make the key blade thinner and cause the key blade to be easily damaged
