Abstract

The invention relates to a lock accessory, and provides a noise reducing mechanism of an inclined tongue assembly. The noise reducing mechanism is provided with a lock box, the inclined tongue assembly, a handling stirring part and an inclined tongue stirring plate. The inclined tongue assembly is arranged in the lock box, the back end of an inclined tongue is connected with a pulling rod, the back end of the pulling rod is provided with a positioning ring, and an inclined tongue guide sheet penetrates through the pulling rod. Two O-shaped rings B, a gasket, two O-shaped rings A, a rubber gasket fixing sleeve and a reset spring penetrate through the pulling rod in front of the inclined tongue guide sheet in sequence. The handling stirring part is embedded in a stirring part embedded hole, and the handling stirring part and the inclined tongue stirring plate are fixed in an embedded mode. When the inclined tongue assembly moves, the O-shaped rings A produce frictional resistance, and collision noise among parts is lowered; the two O-shaped rings B between the inclined tongue guide sheet and a pulling rod fixing frame also have the buffering effect and can reduce the collision noise.

Description

technical field [0001] The invention relates to a hardware door lock accessory, in particular to a lock body part of the door lock. Background technique [0002] At present, the door locks used in the market will make sound when the door is opened and closed due to the collision and friction between the internal parts of the lock body. It is hoped to reduce this kind of noise as much as possible. The existing disclosed technology is as described in the patent CN01220208798.5 "a silent door lock". There is a cushioning and mute effect when the tongue is extended, but there is no cushioning and mute effect when the lock tongue is retracted, and there is no damping for the movement of the lock tongue. The movement of the lock tongue is faster, which also increases the impact noise between internal parts. Contents of the invention [0003] The purpose of the present invention is to solve the noise problem generated by the collision and friction of the bolt assembly inside th...
