Anti-technically opened keyhole closed anti-theft lock and separated-shaped anti-theft key

Abstract

The invention discloses an anti-technically opened anti-theft lock capable of automatically closing a lock hole for back locking and a separated-shaped anti-theft key. According to the invention, in unlocking, an original anti-theft key is automatically divided into two sections by the anti-theft lock when being inserted into the anti-theft lock, simultaneously, the sections are separated by an ''anti-theft door'' of the anti-theft lock, one of the two sections is a ''sole password'' for verifying an inner lock cylinder, the other section is used as a power transmission point for outer unlocking, i.e., manual operation, and then the original anti-theft key rotates along the axis of a spring bolt and further pokes the lock cylinder to unlock; while a non-original key is inserted into the anti-theft lock, if the ''sole password'' lacks, the anti-theft lock can not be unlocked even if the automatic separation structural function is provided, further, any technical operation cannot be performed on the ''anti-theft door'' of the anti-theft lock outside the anti-theft lock, only the lock cylinder is allowed to idle and the spring bolt cannot be poked by rotating, so the anti-theft lock and the anti-theft key disclosed by the invention have very high anti-theft safety.

Description

technical field [0001] The invention relates to an anti-theft lock and an anti-theft key, in particular to an anti-theft lock and an anti-theft key which are high-end anti-opening technology, anti-sabotage, easy to produce and convenient to use. Background technique [0002] Commonly used idle locks on the market are divided into pin locks and shrapnel locks. The specific structure and unlocking principle are as follows. [0003] The structure of the key 1' and the tumbler lock 2' is as follows figure 1 As shown, uneven key teeth 11' are arranged on the key 1'. Pin lock 2 ' mainly comprises lock body 21 ', pin cylinder 22 ', pin 23 ', spring 24 ', rotary bolt and dead bolt. The cylindrical pin lock cylinder 22' is set in the lock body 21' in a rotatable manner, and a key hole for inserting a key is opened on the pin lock core 22'; the spring 24' and the pin 23' are arranged on the pin lock core 22' Inside, the pin 23' adopts a cylindrical structure with different lengths ...

AI Technical Summary

Problems solved by technology

[0009] It can be seen that the security of the existing pin lock 2' and shrapnel lock is relatively poor, and the existing key 1' also needs to be improved accordingly in structure to improve the anti-technical opening function
