Automatic safety protection lock

Abstract

The invention relates to an automatic safety protection lock which comprises a lock bolt automatic reset mechanism. The lock bolt automatic reset mechanism comprises an idler wheel, a linkage rod, a spring and a shifting plate. The idler wheel is arranged on a side edge, close to a lock tongue, of a base, the front end of the linkage rod is connected with the idler wheel, the back end of the linkage rod is connected with the shifting plate in an abutting mode, the linkage rod is sleeved with a spring, and an oblique face is formed at the lower end of the shifting plate forms. A linkage mechanism of the lock bolt mechanism comprises a push plate, a push face corresponding to the oblique face on the shifting plate is formed at the back end of the push plate, and then linkage resetting of the push plate can be achieved through movement of the shifting plate. According to the automatic safety protection lock, the lock bolt mechanism, a clutch, a key knob drive body, the base and the like are all designed into one module and can be independently installed and replaced, so the automatic safety protection lock is convenient to use.

Description

technical field [0001] The invention relates to an automatic security lock. Background technique [0002] The existing electric control security lock has two sets of unlocking systems, mechanical and electronic. Both the mechanical and electronic methods use the key knob drive body on the lock body to drive the lock tongue to move with the push plate to realize the opening / closing of the lock tongue. The method is to insert the key into the key shaft in the key knob driving body, the key shaft rotates with the key, and the dial wheel connected to the other end of the key shaft moves to drive the lock tongue to move with the push plate to realize the opening / closing of the lock tongue. The electronic method is that the electromagnet forms a linkage connection with the pin shaft through a lever mechanism, and the pin shaft and the dial form a synchronous linkage cooperation, so the dial action can be realized, and the lock tongue can be driven to link with the push plate to re...

AI Technical Summary

Problems solved by technology

Since both the mechanical and electronic unlocking systems use the key knob driver together, the load on the key knob driver is increased, the failure rate of the key knob driver is increased, and the service life of the security lock is indirectly shortened.

Moreover, the entire set of electronically controlled security locks is composed of many loose parts, and the assembly and maintenance are not convenient.
