Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a slide rail positioning return device, by means of the first fixing part of the fixing seat and the second fixing part of the sliding mechanism It is located in the middle rather than on both sides, so that the elastic force of the elastic member can be centered without deviation, and it can avoid or reduce the movement between the fixed seat and the sliding mechanism. wear and tear, which leads to the reduction of product service life, so that this creation can achieve the effect of improving product service life and ease of use

Embodiment Construction

[0023] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0024] Such as figure 2 , image 3 Shown is a slide rail positioning return device, including:

[0025] A slide rail mechanism 3, the slide rail mechanism 3 includes an outer slide rail 31, a middle slide rail 32 and an inner slide rail 33, the middle slide rail 32 slides in the outer slide rail 31, and the inner slide rail 33 Slidingly connected in the middle slide rail 32, so that the smaller slide rail can slide and shift relative to the larger slide rail, and the detailed structure mode and action principle of each slide rail of the slide rail mechanism 3 belong to the prior art and It is not a technical feature of the wooden case, so it will not be described in detail here. The outer slide rail 31 is provided with a first through hole 311, and one end of the inner slide rail 33 is provided with a toggle portion 34, and the toggle portion 34 is c...

Abstract

The invention discloses a slide positioning and returning device, which comprises a slide mechanism, a fixed seat and a sliding mechanism. The slide mechanism comprises an outer slide, a middle slide and an inner slide. A snapping portion is arranged at one end of the inner slide and provided with a notch. The fixed seat is fixed inside the outer slide of the slide mechanism. A first fixed portion is disposed in the middle of one end of the fixed seat. A groove is reserved in the fixed seat and provided with a notch on one side. The sliding mechanism and the fixed seat penetrate each other. The sliding mechanism comprises an elastic part. Two ends of the elastic part are fixed to a second fixed portion and the first fixed portion respectively. The first fixed portion of the fixed seat and the second fixed portion of the sliding mechanism are not disposed on two sides but in the middle, so that elasticity force of the elastic part is centered without offset. A point of application of the elastic force of the elastic part is centered without offset, so that unsmooth action of the mechanisms can be avoided or lessened, and the service life of products is prolonged. The length of the middle slide can be increased and loading capacity of the middle slide can be improved.

Description

Technical field: [0001] The invention relates to a positioning return device, especially the elastic force of the elastic member can be placed in the center without deviation, so as to avoid or reduce the problem that the movement between the fixed seat and the sliding mechanism is not smooth, resulting in a reduction in the service life of the product. Furthermore, it is a slide rail positioning and returning device that can achieve the effect of improving product service life and ease of use. Background technique: [0002] Ordinary slide rail positioning and returning devices, such as Taiwan Patent No. I319465 "A buffer type self-closing device for slide rail mechanisms", as attached figure 1 As shown, the slide rail mechanism includes a fixed outer frame and at least one movable slide rail group 2, the movable slide rail group 2 may include a middle slide rail 21 and an inner slide rail 22, and the buffer type self-closing device includes : a fixed seat 10 fixed on the f...
