Reinforced drawer guide rail

Abstract

The invention relates to a reinforced drawer guide rail, which is a drawer guide rail operating more straightly, belonging to the furniture field. The drawer guide rail comprises more than two sections of sliding rails which slide relatively. A ball retainer is arranged between two adjacent sliding rails, wherein the first sliding rail is connected under the drawer and one supporting wheel is arranged on a second sliding rail adjacent to the first sliding rail. The supporting wheel is arranged on the upper plane at the front end of the second sliding rail through a supporting wheel frame. The front end of the second sliding rail is provided with a clamping hole and four positioning pieces. The supporting wheel frame is provided with two buckling pieces, two positioning grooves and two half shaft holes. The two ends of the supporting wheel frame for the supporting wheel are embedded in the two half shaft holes of the supporting wheel frame. The two buckling pieces of the supporting wheel frame are buckled with the two edges of the clamping hole. The four positioning pieces are inserted into the two positioning grooves of the supporting wheel frame. The supporting wheel is in sliding contact with the lower plane of the first sliding rail. The invention has the advantages of simple structure and remarkable effect, and is suitable for being assembled on all two-section guide rails and three-section guide rails.

Description

technical field [0001] The invention belongs to the field of furniture, in particular to a drawer guide rail which operates more smoothly. Background technique [0002] Multi-section guide rails are widely used in the drawers of high-end furniture. The most common is the three-section guide rail, which consists of a movable rail, a middle rail, and a fixed rail. There are rollers or balls between the movable rail and the middle rail, and between the middle rail and the fixed rail. , the rollers and balls are restrained by the cage [0003] (There are only movable rails and fixed rails in the two-section guide rail, and there is a ball cage between the movable rail and the fixed rail). Since the length of the cage is shorter than the length of the slide rail, the movable rail has a cantilever beam structure relative to the middle rail. Relative to the fixed rail, it also has a cantilever beam structure (the movable rail of the two guide rails has a cantilever beam structure ...

AI Technical Summary

Problems solved by technology

[0003] (There are only movable rails and fixed rails in the two-section guide rail, and there is a ball cage between the movable rail and the fixed rail). Since the length of the cage is shorter than the length of the slide rail, the movable rail has a cantilever beam structure relative to the middle rail. The relative fixed rail also has a cantilever beam structure (the movable rail of the two guide rails has a cantilever beam structure relative to the fixed rail). Under the weight of the drawer and the objects loaded in the drawer, the front end of the drawer will sink a little, especially when the drawer is completely closed. When the front of the drawer sinks, the drawer panel is tilted, and there is a gap between the top of the drawer panel and the drawer cabinet, which destroys the beauty of the furniture. This is an urgent need for improvement.
