A kind of anti-collision locking mechanism

Abstract

The invention relates to an anti-collision lock body mechanism. A lock body is formed by a lower shell, a face plate, a connecting plate and an anti-collision plate, wherein the face plate is distributed and welded on the connecting plate to form an integral plate, then the integral plate is installed at the headmost end of the lower shell, and the anti-collision plate is distributed and installed inside the lower shell and at the back of the integral plate to form a new anti-collision lock body system. According to the anti-collision lock body mechanism, a main lock bolt is lengthened, and the anti-collision plate is increased, so the principle of height positioning points of the lock bolts of the lock body is changed to protect the inner structure of the lock body. When external force is exerted on the main block bolt and a counter lock bolt, a face plate hole and a fracture surface serve as supporting points of the main lock bolt and the counter bolt hole, and a main lock bolt hole and a counter lock bolt hole of the anti-collision plate serve as the height positioning points of the main lock bolt and the counter lock bolt. Due to the fact that the height positioning points are located in the main lock bolt hole of the counter lock bolt hole of the anti-collision plate, the anti-collision plate bears all collision strength, inclination of the lock bolt cannot be caused, and the inner structure of the lock body is protected.

Description

technical field [0001] The invention relates to a lock body, in particular to an anti-collision lock body mechanism. technical background [0002] In the field of existing lock body quality and safety factor, the panel is usually connected with the upper and lower shell edges through three U-shaped connecting blocks. The main lock tongue is guided through the panel hole and the screw connection column in the middle, and the slider 2 and the washer are positioned as the high bottom. The main lock tongue is driven in and out by the lock cylinder, the reverse lock tongue is also guided by the panel hole and the sliding groove of the lower shell, and the bending height of the tail of the reverse lock tongue is used as the height positioning. The back-and-forth rotation of the anti-lock block drives the anti-lock tongue to move in and out. [0003] Due to defects in design, the existing lock bodies have the following shortcomings: [0004] 1. When the door is locked, many crim...
