Single-body wide lock latch and parallel movable-type lock core connected main lock body structure

Abstract

Disclosed is a single-body wide lock latch and parallel movable-type lock core connected main lock body structure. A conventional mode that an inserting-core-type lock core is matched with a mechanical antitheft lock is changed, and a marble structure in opposite double-row arrangement and mounted in a parallel movable-type lock core can improve a technical-opening-preventive function of a main lock body. Due to a unique structural form that a single-body wide lock latch is connected with the parallel movable-type lock core and a method for realizing locking and unlocking by directly pushing and pulling a key, more simplicity and more practicability are realized. The whole main lock body is simple in structure and few in part, so that a lot of production raw materials can be saved, manufacturing processes are reduced, and labor cost is lowered.

Description

technical field [0001] The invention relates to a mechanical anti-theft lock matched with a mortise-type lock cylinder, in particular to a main lock body structure in which a single wide lock bolt and a parallel-moving lock cylinder are integrated Background technique [0002] Known traditional mortise type mechanical anti-theft lock is made up of two parts of mortise type lock cylinder and main lock body of mechanical anti-theft lock. The pins in the mortise lock cylinder have a one-way single-row structure, and its anti-technical and violent opening functions are poor. In terms of manufacturing, special equipment and materials are required, and the accuracy of the production process is also very high. , also need more than a dozen production processes; the internal structure of the main lock body of the mechanical anti-theft lock is more complicated, plus more than 5 lock bolts (tongues), there are more than 30 parts, and a total of more than 50 production processes are re...

AI Technical Summary

Problems solved by technology

The pins in the mortise lock cylinder have a one-way single-row structure, and its anti-technical and violent opening functions are poor. In terms of manufacturing, special equipment and materials are required, and the accuracy of the production process is also very high. , also need more than a dozen production processes; the internal structure of the main lock body of the mechanical anti-theft lock is more complicated, plus more than 5 lock bolts (tongues), there are more than 30 parts, and a total of more than 50 production processes are required, plus Factors such as the consumption of raw materials and the increase in labor costs year by year make the production cost of mechanical anti-theft locks higher and higher, and the profits of manufacturers are getting lower and lower.
