Drawer guide rail with buffer resetting and pressing rebound opening functions

Abstract

The invention discloses a drawer guide rail with buffer resetting and pressing rebound opening functions; the drawer guide rail comprises an inner rail, a middle rail and an outer rail which are sequentially wrapped from inside to outside, wherein the two adjacent rails are connected through a ball mechanism; a sliding seat is fixedly arranged at the tail end of the outer rail; a guide rail is arranged on the sliding seat; a buffer frame is arranged on the guide rail in a front-back sliding mode; a reset tension spring and a damper are arranged between the sliding seat and the buffer frame, and the reset tension spring generates tension to pull the buffer frame in the closing direction all the time; a rebound sliding block is arranged on the guide rail in a front-back sliding mode; a rebound tension spring is arranged between the rebound sliding block and the sliding seat, wherein the rebounding sliding block is always pulled towards the opening direction of the guide rail by the rebound tension spring. The drawer guide rail has the advantages that the press rebound type opening function is achieved, and the operation convenience of the guide rail can be effectively improved. Whenthe guide rail is closed, a buffer reset function is achieved, so that the drawer can be closed slowly, working noise generated when the guide rail is in collision with a limiting part is avoided, andthe operation quality is improved.

Description

technical field [0001] The invention relates to a hardware accessory, in particular to a drawer guide rail with the functions of cushioning reset and pressing and rebounding to open. Background technique [0002] At present, the drawers of various desks are equipped with slideable drawer guide rails. In order to make the drawer close to the desk after being closed, it looks neat and beautiful. The method in the prior art is to adopt the self-closing angle guide rail of international general design, and a section of guide rail inclined downward is provided at the rear end of the fixed rail, so that the front roller of the sliding rail mounted on the drawer walks to the inclined section. It slides down automatically under the action of its own weight, so as to ensure that the drawer is completely closed. However, this self-closing angle guide rail has always had the following disadvantages: 1. When the rollers of the slide rail are pushed to the lower end, the drawer's own w...

AI Technical Summary

Problems solved by technology

However, this self-closing angle guide rail has always had the following disadvantages: 1. When the rollers of the slide rail are pushed to the lower end, the drawer's own weight alone makes the rollers only slide down on a slope of 3.5 degrees to 5 degrees, and the sliding closure is not obvious , the use effect is very unsatisfactory; 2. Due to the small bending angle, when the drawer is slightly inclined outward, it will slide out and fall to the ground; 3. Due to structural reasons, when the fixed slide rail is bent, it will not be fixed at the bending point. The connection may be smooth, so when the drawer is pushed and pulled, there is always a feeling of going uphill and downhill, which is difficult to meet the user's requirements; 4. Since the drawer does not have a self-locking function, when moving the table, the drawer is easy to slide out under the action of its own weight , causing inconvenience in moving
