Impact-resistant and anti-rebound sliding rail

Abstract

The invention provides an impact-resistant and anti-rebound sliding rail which comprises a static rail and a movable rail. The static rail comprises a top plate I, a base plate I and side plates I forming a sliding groove and is provided with a static rail first end and a static rail second end, and the static rail first end is used for installing a first pulley. The movable rail comprises a top plate II, a base plate II and side plates II, the top plate II downward extends to form an upturned edge. The movable rail is provided with a movable rail first end and a movable rail second end, the movable rail first end is used for installing a second pulley, at least two protrusions playing an impact-resistant buffering effect are formed on the inner wall of the top plate II and are of asymmetric structures, and the separation distance between the two adjacent protrusions is preset. A downward protruding stop portion I is formed on the inner wall of the top plate I, an upward protruding stop portion II is formed on the inner wall of the base plate II, the stop portion I and the stop portion II are located at the second end of the static rail, and a limiting portion for preventing the movable rail from rebounding and regressing is arranged on the inner wall of the top plate I in a protruding mode and is an elastomer of an asymmetric structure.

Description

technical field [0001] The invention belongs to the technical field of hardware, and relates to a slide rail, in particular to an impact-resistant and rebound-resistant slide rail. Background technique [0002] The slide rail is a hardware connecting part fixed on the cabinet body of the furniture for the drawer or cabinet board of the furniture to move in and out. The slide rail is suitable for the drawer connection of wooden and steel drawers such as cabinets, furniture, office cabinets, and bathroom cabinets. [0003] At present, there are mainly three types of slide rails: roller type, steel ball type, and gear type. The roller type drawer slide rail has the advantages of simple structure and low noise. It is mainly composed of rollers and two rails, which can meet the daily push and pull needs. [0004] The existing slide rail has a large contact area when sliding, so the friction force generated is also relatively large, which not only makes the slide rail wear more se...

AI Technical Summary

Problems solved by technology

[0004] The existing slide rail has a large contact area when sliding, so the friction force generated is also relatively large, which not only makes the slide rail wear more serious, but also produces relatively large noise, and due to the large friction force, the sliding is not smooth, and it is easy to occur Misalignment, causing misalignment and jamming, etc., which affects daily use

[0005] Unsmooth sliding is likely to cause continuous inconvenience. Due to the unsmooth sliding, the user generally exerts a large force when pushing and pulling. When closing, the cushioning performance of the slide rail is poor, and the impact resistance is weak, which is easy to cause violent impact. , which produces a lot of noise, and will affect the strength of the slide rail in the long run, resulting in deformation of the slide rail

In addition, under the violent impact, the drawer is prone to retreat, rebound, and automatic opening, etc., often causing the drawer to not close tightly.
