Self-closing device of sliding rail component

Abstract

The invention provides a self-closing device of a sliding rail component. The self-closing device of the sliding rail component can be used for solving the problems that an existing device is big in assembling difficulty and low in efficiency and damage can be easily caused. A main body is fixedly arranged at one side edge of a fixed guide rail, a sliding guide rail is slidably assembled on the fixed guide rail, a sliding block is contained in the cavity extending along the moving direction of the sliding guide rail inside the main body, and symmetric guide grooves are formed in the two side walls of the cavity, so that the sliding block can move along the guide grooves; a pawl is downward fixedly arranged on the sliding guide rail and can be in fit with the sliding block, an integrated extending part is arranged at the rear end of the main body, a damping piece mounting slot extending in the same direction of the cavity is formed in the extending part, a damping piece is fixedly mounted in the damping piece mounting slot, a piston rod of the damping piece is fixedly connected with the rear end of the sliding block by virtue of a small hole which is formed in the front end surface of the damping piece mounting slot and runs through the cavity, and a spring slot is formed in the bottom of the extending part, runs through the cavity and is used for containing a spring with one end fixed with the rear end of the spring slot and the other end connected with the sliding block.

Description

technical field [0001] The invention relates to the technical field of drawer slide rails, in particular to a self-closing device for slide rail components. Background technique [0002] In the existing drawer slide rail structure, most of the drawer slide rails do not have the function of automatic recovery, which causes the user to apply a pushing force all the way to completely close the drawer. Violent collisions and even drawer rebounds can easily cause damage to the cabinet; and when the force is too small, the drawer cannot be completely closed, especially for the drawer in the refrigerator, it is easy to cause the contents in the refrigerator drawer to come into contact with the surrounding air, thus failing to achieve Food preservation requirements. [0003] At present, some drawer slide rails in this field are equipped with automatic closing devices, through which the automatic closing function of the drawer after being pushed to a certain position is realized.
