Sliding rail return mechanism

Abstract

The invention relates to a sliding rail return mechanism, in particular to a sliding rail return mechanism, which can realize simple and easy return, simple structure, quick assembly and cost conservation. The sliding rail return mechanism comprises an outer sliding rail, a middle sliding rail and an inner sliding rail, wherein one end of the outer sliding rail is provided with a fixed seats, an accommodating space is formed in the fixed seat, a groove is formed on one side of the accommodating space, one end of the fixed seat is provided with a notch, the two sides of the fixed seat are provided with fixing parts, a sliding piece is arranged in the outer sliding rail, the sliding piece is provided with a clamping part through one-step forming, the clamping part is inserted into the accommodating space in the fixed seat, a concave opening part is formed on one side of the clamping part, a first contact part is formed on one side of the concave opening part, a second contact part is formed on the other side of the concave opening part, elastic pieces are arranged on two sides of the sliding piece, and one end of each elastic piece is fixedly arranged on the fixing part of the fixedseat; the middle sliding rail is arranged in the outer sliding rail and is contacted with one side of the sliding piece; and one side of the inner sliding rail is provided with a driving piece which is stopped at the concave opening part of the clamping part.

Description

Technical field: [0001] The invention relates to a slide rail return mechanism, in particular to a slide rail return mechanism capable of simple return, simplified structure, fast assembly and cost saving. Background technique: [0002] Taiwan patent "Automatic closing device for slide rail", which is an automatic closing device composed of a fixed frame, a slider, two springs, a sliding hook and a linkage, so as to have the effect of automatic closing. This patent is based on this The thickness of the sliding seat of the fixed frame is relatively thin to prevent the middle sliding rail from interfering with the front side of the sliding seat when it slides backwards, and there is no need to open a large area of ​​open slots on the rear side of the middle sliding rail To avoid the sliding seat, so as to increase the structural strength and expand the load range of the slide rail, thereby improving the applicability of the slide rail; [0003] Although the "automatic closing...

Problems solved by technology

[0003] Although the "automatic closing device of the slide rail" can improve the applicability of the slide rail, the automatic closing device is composed of a fixed frame, a sliding block, two springs, a sliding hook and a linkage, and the sliding hook There are pivots, guide posts, positioning hook grooves, arc protrusions and positioning grooves. Therefore, the automatic closing device has many components, resulting in complex overall structure, slow assembly speed and expensive manufacturing process. Therefore, it is often used by users. sick;
