Anti-shaking device with spring bolt split

Abstract

The invention discloses a lock tongue split type anti-sway device, which comprises a lock tongue and an anti-sway block slidably connected to the lock tongue. An anti-sway block is slidably connected to the left and right sides of the lock tongue. The upper part is an anti-sway oblique block, and the lower part of the anti-sway block is a sliding cylinder. The two sides of the lock tongue are provided with circular chute, and the sliding cylinder is located in the circular chute. The sliding cylinder is provided with a circular blind hole, and the circular There is a spring between the shaped blind hole and the deadbolt bottom plate. The structure of the invention is simple. The two sides of the original lock body are pressed synchronously to prevent the door from shaking. After long-term use, the lock tongue is not located in the center of the lock tongue insertion hole when the door is closed due to friction, and the two sides of the door can also be prevented from shaking by relying on the different pushing distances of the anti-shake sliders on both sides.

Description

technical field [0001] The invention relates to a lock body, in particular to a lock tongue split type anti-sway device. Background technique [0002] The lock body is one of the components of the lock. There are many kinds of lock bodies, such as one-way lock body, three-way lock body, and four-way lock body. Generally used on anti-theft doors, it is responsible for the basic anti-theft work of anti-theft doors. The lock cylinder controls the operation of the lock body, and the lock body is responsible for opening and locking the doors and windows, and plays an important role in anti-theft. At present, there is an anti-shake trapezoidal block slidingly connected to the bolt of the lock body. After the lock body is used for a period of time, after the bolt insertion hole on the door frame becomes larger, the trapezoidal block is pushed out more, so that the two hypotenuses of the trapezoidal block are pressed. The two sides of the lock tongue insertion hole are tight to pre...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a lock tongue split type anti-sway device, which solves the problem that the two hypotenuses of the trapezoidal block in the prior art are pressed against the two sides of the lock tongue insertion hole to prevent the door from shaking after long-term use. When closing the door so that the deadbolt is not in the middle of the deadbolt insertion hole, the door will still have the problem of shaking on the side that is not pressed
