Description

technical field [0001] The invention belongs to the field of furniture, in particular to an accessory of a drawer guide rail. Background technique [0002] The high-grade drawer guide rail products are equipped with a set of guide rail return buffer device, which makes the drawer snapping more stable and quiet. The return buffer device of the guide rail is mainly composed of a bracket, a slider, a setting needle, a damping cylinder and an energy storage spring; the bracket is fixed on the fixed rail, the slider, the damping cylinder and the energy storage spring are installed on the bracket, and the slider moves along The upper guide groove slides, and the dial pin is fixed on the movable rail. At the initial stage of pulling out the drawer, the dial pin pulls the slider to move outward, and the energy storage spring connected to the slider is stretched and connected to the slider. The damping cylinder is reset, and then the setting pin is separated from the slider and the ...

AI Technical Summary

Problems solved by technology

Because the energy storage spring and the damping cylinder of the prior art guide rail return buffer device are arranged in parallel, the overall width is relatively large, so it is not suitable for installation on a drawer guide rail with a small width; secondly, the guide rail return buffer device of the prior art The slider is guided and deflected by a guide groove on the bracket, which is prone to failures that are not easy to lock in the deflected state, and it is necessary to improve
