Dislocation drive-type cross mechanical anti-theft lock

Abstract

The invention relates to a dislocation drive-type cross mechanical anti-theft lock. The dislocation drive-type cross mechanical anti-theft lock comprises a lock body, a lock core, a lock hole, a fixing ring, a rotating ring, a drive mechanism, and a matched key. The dislocation drive-type cross mechanical anti-theft lock is characterized in that each marble group is composed of four round beaded marbles with the same diameters and a cylindrical marble; two marble groups are formed according to difference of the order of the marbles; the distance between the crest height and the valley depth of tooth shape of the matched key is the diameter of each round beaded marble; the rotating ring is arranged at the periphery of the fixing ring; the rotating ring is provided with an unlock pin and a lock pin; a lantern ring is connected with and fixed at the periphery of the rotating ring through a bolt; a limiting ring is also arranged outside the rotating ring; the limiting ring is fixed on a steel plate at the outer side of the lock body; a bump of the limiting ring is meshed with the bump of the rotating ring; a marble hole in the lock core is oppositely misplaced with corresponding marble hole in the lock body when the matched key begins to rotate, and then the rotating ring begins to rotate under the drive of a lifting ring through an opening on the rotating ring, and drives an unlock execution mechanism to move at the same time, so as to finish unlocking of a lockset.

Description

technical field [0001] The invention relates to a mechanical anti-theft lock, in particular to a dislocation transmission cross mechanical anti-theft lock. Background technique [0002] A mechanical lock generally consists of a lock body, a lock cylinder, a transmission mechanism, and a dead bolt (bolt). The lock cylinder is the key component, which contains the tumbler group. The movement and movement range of the marbles are determined by the key. Only when the correct key is encountered, the marbles can move to the correct position, and the lock cylinder can rotate or move in other forms, and then drive the transmission mechanism to complete the unlocking action. Because there is a certain connection between the pin and the transmission mechanism, technical opening locks often use this connection in combination with special special tools to move the pin or other related components to the required position, and finally open the lock. [0003] The smaller the level differ...

Problems solved by technology

However, the general precision requirements are high, and the manufacturing difficulty and cost are also high, which may lead to a decrease in mechanical strength. Therefore, some special high-quality materials are used to improve the anti-destructive ability.

There are also locks with strong anti-opening ability, but the unlocking operation process is relatively cumbersome.

But no matter how it changes, the design of most locks has a common feature, that is, before the action of the unlocking mechanism, each pin group (or parts such as blades) and other related unlocking actuators are always in contact with each other or in a certain relationship. , making it possible for technology to open the lock
