Mute opening and closing structure for sliding rails

Abstract

The invention relates to a mute opening and closing structure for sliding rails. The mute opening and closing structure for the sliding rails comprises a movable sliding rail, a middle sliding rail and a fixed sliding rail; a first protective frame is arranged between the movable sliding rail and the middle sliding rail; the movable sliding rail and the middle sliding rail are in sliding connection through the first protective frame; a second protective frame is arranged between the middle sliding rail and the fixed sliding rail; the middle sliding rail and the fixed sliding rail are in sliding connection through the second protective frame; sliding opening and closing among the movable sliding rail, the middle sliding rail and the fixed sliding rail is realized; a movable piece is arranged on the movable sliding rail; the movable piece is arranged on the movable sliding rail elastically and movably and follows the movable sliding rail to be opened and closed on the middle sliding railand the fixed sliding rail in a sliding way; when the movable piece is opened to a certain position in a sliding way, the elasticity of the movable piece acts on the middle sliding rail or the fixedsliding rail; when the movable piece is closed to a certain position in a sliding way, the elasticity of the movable piece acts on the first protective frame or the fixed sliding rail or the middle sliding rail; and sliding mute opening and closing among the movable sliding rail, the middle sliding rail and the fixed sliding rail is realized. The problem that the plurality of sliding rails collidewith one another during sliding opening and closing or cannot perform positioning is effectively solved, so that the service life of products is prolonged and the use experience of users is improved.

Description

technical field [0001] The invention relates to a silent opening and closing structure for slide rails. Background technique [0002] The Chinese patent literature number is CN204120568U, which discloses a position-limiting and stable structure of a drawer slide rail on January 28, 2015. The middle rail between the movable rail and the movable rail. The three rails are slidingly connected to each other through the synchronous wheel. The synchronous wheel is made of plastic and is rotatably set on the middle rail. Sliding is provided with a sliding bracket assembly, and the synchronous wheel acts on the fixed rail, the movable rail, and / or the sliding bracket assembly; the synchronous wheel is a gear plate structure with the functions of both limiting and increasing strength. The slide rails of this structure cannot achieve the silent opening and closing effect in the actual use process, and there will always be problems of collision with each other, which will affect the se...

AI Technical Summary

Problems solved by technology

The slide rails of this structure cannot achieve the silent opening and closing effect in the actual use process, and there will always be problems of collision with each other, which will affect the service life of the product and the user experience. At the same time, there will be up and down during the sliding process. The phenomenon of jumping and shaking from side to side
