Anti-theft lock and its key

Abstract

The invention relates to an anti-theft lock and a key thereof. A central line of outer pin tumbler mounting grooves and inner pin tumbler mounting grooves is arranged in the 0.2-0.5 mm position on one side of a vertical line of centers of an outer lock core and an inner lock core; through sliding plug column mounting grooves are formed in the inner lock core on the other side of the vertical line of the centers of the outer lock core and the inner lock core; middle parts of the sliding plug column mounting grooves are communicated with a key hole; a sliding plug column is movably mounted in each sliding plug column mounting groove; a sliding positioning block is arranged in the position, close to the circumferential direction of the inner lock core, of the upper parts of the sliding plug column mounting grooves; the sliding positioning block is mounted on one sides of the sliding plug columns through bolt springs; a sliding positioning block groove matched with the sliding positioning block is formed in the outer lock core. When in use, the sliding plug columns are mounted for use in a matching manner, so that the space of the key hole is reduced, and the effect of preventing technology unlocking is achieved, and since the anti-theft lock is equipped with the sliding positioning block, a more obvious positioning effect is achieved, and false unlocking is avoided.

Description

technical field [0001] The invention relates to the security field, in particular to an anti-theft lock and a key thereof. Background technique [0002] Anti-theft locks are the main mechanical locks currently on the market. According to the different principles of the lock cylinder, anti-theft locks can be divided into tumbler locks, blade locks, magnetic locks, IC card locks, fingerprint locks, etc. Pin locks and magnetic locks are more common. Slot locks, cross locks, computer locks, etc. all belong to tumbler locks; magnetic locks were more popular in the past few years, but they are relatively rare in the past two years. Pin locks, also known as pinball locks, bead locks, bolt locks or pin locks, are the most common lock structure. The principle is to use multiple lock springs, pins or beads of different heights to lock the lock cylinder. When the correct key is put in, each lock bolt is pushed to the same height, and the lock cylinder is released. The structure of ...

AI Technical Summary

Problems solved by technology

The reserved space in the key hole of the traditional tumbler lock is relatively large, and it is relatively easy to realize technical unlocking

Moreover, the mis-opening rate of the traditional tumbler lock is high, and its safety level and insurance are poor.

Although there are some anti-theft locks with higher security levels on the market, their production costs are high, their structures are complicated, and their installation and disassembly are inconvenient, so they are not suitable for large-scale production and use.

With the development of science and technology and the improvement of people's requirements for the security level of anti-theft locks, this traditional pin lock can no longer meet the needs of the market.
