Abstract

The invention refers to a building household door lock, and particularly to a lock body structure of a mute door lock with smaller noise. The invention provides a mute lock body structure, and the mute lock body structure solves the problem of sound of collision and friction between internal members of the door lock. The technical scheme of the invention is: the lock side of a lock box is provided with a three-fork tongue hole, a square tongue hole and a square tongue silencing block; a three-fork tongue silencing sleeve is built in the three-fork tongue hole, and a three-fork tongue is embedded in the three-fork tongue silencing sleeve; the middle of the three-fork tongue is provided with a silencing frictional tongue, the back end of the three-fork tongue is fixedly connected with a slide rod, and the back end of the slide rod is provided with a slide rod silencing block; the square tongue silencing block is embedded in the square tongue hole, and a square tongue is embedded in the square tongue silencing sleeve, and its back end is fixedly connected with a slide block; multiple roller bead braces are arranged on the slide block, and a roller bead is respectively embedded in each of the roller bead brace respectively. Through the technical scheme, the mute lock body structure adopts a lot of silencing plastic materials, and thereby avoiding the direct collision and friction between metals, comprehensively reducing the noise generated by the movement of the internal lock body structure, and making the lock body reach a good mute effect.

Description

technical field [0001] The invention relates to a door lock for construction and home use, in particular to a lock body structure of a silent door lock with less noise. Background technique [0002] Currently used door locks, its components are usually made of metal materials, when opening and closing the door, because of the impact or friction between the parts, noise will be emitted. With the improvement of people's consumption level, it is hoped to reduce such noise as much as possible in office or home. Many inventors have proposed corresponding solutions from different technical angles: CN203050243U discloses a low-resistance silent door lock, which adopts a soft lock box roller installed at the front end of the lock box, and a soft buckle installed at the front end of the buckle box. The box guide roller, the scheme of installing soft buckle box shrapnel in the buckle box, can slow down the noise caused by the friction or collision between the lock tongue and the lock...
