Lock using push plates for transmission

Abstract

The invention relates to the technical field of locks, in particular to a lock using push plates for transmission. The lock comprises a lock tongue panel, a square tongue, a square tongue transmissionmechanism, a lock shell and a lock cylinder assembly; the lock tongue panel is provided with a square tongue extending and retracting opening; the square tongue transmission mechanism comprises a longitudinal push plate and a sliding push plate; the lock cylinder assembly comprises a lock cylinder, a locking rotating seat and a shifting piece; the shifting piece is connected with a square tongueshifting rod which extends outwards in a bending shape; the shifting piece is connected with and fixed to the locking rotating seat; the upper end of the longitudinal push plate is bent; the upper endand the lower end of the longitudinal push plate are parallel to each other, so that the longitudinal push plate is in a Z shape; and the press-fit end is arranged at the upper end of the longitudinal push plate. The lock adopts the specially structural longitudinal push plate and the sliding plate to achieve transmission, the transmission structure in the lock is simpler, and the stress is moredirect, so that the lock is lower in production and assembly cost, lower in mounting and maintaining ratio, more compact in structure, smaller in whole size and wider in application range.

Description

technical field [0001] The invention relates to the technical field of lock bodies, in particular to a lock body driven by a push plate. Background technique [0002] With the improvement of people's living standards, family security has become more and more important. House access control is the most direct and important security protection for families. It is extremely important to choose which lock to install. Most of the lock tongues of the existing lock body adopt the transmission connection mode of the pull rod and the multi-segment connecting rod to connect the clutch assembly and the lock tongue, so that the lock tongue can realize expansion and contraction under the rotation of the clutch assembly, but the installation of the pull rod and the multi-segment connecting rod transmission structure is complicated and easy to jam Dead, the maintenance cost is high, the installation takes up a lot of space, and it is necessary to preset a plurality of positioning parts or ...
