Abstract

The utility model relates to a slide-rail structure, comprising a pull-out rail, a supporting rail, a first pulley group and a first fixed pulley group. The supporting rail has a slide-rail, and the slide-rail is for the arrangement of the first pulley group and the fixed pulley group; the slide-rail also has a first limit point and a second limit point, the first limit point and the second limit point are respectively arranged at both ends of the slide-rail to limit the sliding distance of the first pulley group; the fixed pulley group is arranged at the other end of the first limit point corresponding to the first pulley group; and the pull-out rail can be equal to or longer than the supporting rail, and together with the first pulley group and the fixed pulley group are coated and arranged on the slide-rail, and a third limit point and a fourth limit point are arranged at both ends of the pull-out rail. Thereby, when not pulled out, both ends of the pull-out rail and the fixed pulley group bear stress evenly through the first pulley group; when the pull-out rail is pulled out, the fourth limit point is driven by the first pulley group to slide along the slide-rail to move to the first limit point, and thereby, tension effect is achieved.

Description

Rail structure

[technical field]

The utility model relates to the rail structure field, specifically, is a kind of rail structure of can be applicable to stretch cabinet, drawer, makes slide rail slide firm the sliding of Shi Nenggeng.

[background technology]

At present common drawer, Key board drawer etc., for asking the convenience of pulling out and resetting, how can in conjunction with at the bottom of the tool, in, go up the railroad of slide rail, this railroad then utilizes end slide rail to be located at cabinet body, bookcase body both sides or is located on the laminate, last slide rail then with drawer, draw the bottom of basket to combine, convenient drawer, draw basket etc. to be the basis with slide rail at the bottom of cabinet body, bookcase body, the laminate, and by last, in, the sliding part (as steel ball, pulley, roller etc.) that is provided with between the end slide rail, pull out, push the effect that resets with what reach drawer, draw basket.

The general assembly pulley that is widely used most just belongs to single pulley, yet the single assembly pulley of this kind has shortcoming as described below:

(1) too short, pull out easy generation of track and rock;

(2) long, the stroke of pulling out of pulling out track is restricted;

When (3) resetting, load concentrates on supporting track and pulls out in the middle of the track, produces swag phenomenon before and after making.

U.S. Pat 7296863 (Guide rails for pull-out drawer/equipment) is a kind of rail structure with full exhibition effect, it is mainly pulled out track 50 and is formed by a supporting track 30, an assembly pulley 40 and, its supporting track 30 front ends are provided with one first spacing point 39, pull out track 50 sides and be provided with one second spacing point 51, assembly pulley 40 is for supporting track 30 and pulls out track 50 movable groups; Thus, pull out track 50 when making the second spacing point, 51 buttons draw assembly pulley 40 to move to the first spacing point 39 outward, slide rail is promptly finished the effect of the full exhibition that stretches.

Though having assembly pulley, above-mentioned slide rail moves the effect of pulling out to reach, yet its assembly pulley is to be in supporting track to carry the front and back weight of taking advantage of with balance with the middle part of pulling out track after resetting, yet it is comparatively heavy to work as the object that folds, or fold and put the position and disperse uneven, easily make the empty position of thread of pulling out the no assembly pulley of track and supporting track front and back produce beat, and during withdrawn slide rail, because of using single assembly pulley, causing load to concentrate on supporting track and pull out in the middle of the track, be easy to generate swag phenomenon in many ways, cause structure easily impaired drawback of when pulling.

In view of the limited single assembly pulley length of aforementioned slide rail can't be done long the stretching; when sliding, be easy to generate swag phenomenon simultaneously and use single assembly pulley load to concentrate on the single assembly pulley; slide rail is loaded to be evenly distributed in when folding and is caused slide rail impaired drawback easily on the slide rail; the inventor designs a kind of only rail structure of surplus pulley distance of back overlap distance that stretches; and make the spacing of slide rail front and back two assembly pulleys when stretching keep optimum distance forever; and have concurrently reset before and after pulley keep longest distance; effectively get rid of limited the stablizing of slide rail thus and can't do long the stretching; so that slide rail reaches the effect of full exhibition; provide the stretching cabinet need not use long rail structure can reach equal tensile elongation; make the spacing of slide rail two assembly pulleys when sliding and before and after after folding have the longest spacing simultaneously; make slide rail have the most firm support, make slide rail in can be the really average scatteredload of collapse state.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rail structure is provided, and makes it have the effect that slide rail slides and drives, and can reduce the overlap distance between slide rail and slide rail, makes slide rail accomplish the maximum distance of pulling out with the shortest length.

The purpose of this utility model is achieved through the following technical solutions:

A kind of rail structure comprises pulls out track, a supporting track, one first assembly pulley and a fixed block group; This supporting track has a dragging track, this dragging track is provided with for first assembly pulley and fixed block group, this dragging track has one first spacing point and one second spacing point in addition, this the first spacing point and the second spacing point are to be located at the dragging track two ends respectively to limit the first assembly pulley coasting distance, and this fixed block group is located at first spacing some other end with respect to first assembly pulley; This pulls out track can equal or be longer than supporting track, and is arranged on dragging track together with first assembly pulley and the coating of fixed block group, and this pulls out the track two ends one the 3rd spacing point and one the 4th spacing point; Thus, pull out track two ends when not pulling out and can pass through first assembly pulley and fixed block group average force, when pulling out after track pulls out, the 4th spacing point promptly drives first assembly pulley and moves to the first spacing point along dragging track, to reach the effect of stretching.

The good effect of the utility model rail structure is:

The utility model not only can be by first when not spurring, the fixed block group on average supports and pulls out track, reaching stable folds outside the effect, first assembly pulley can be driven to fixed block group position after pulling out, make that the overlap distance of pulling out track and dragging track only is first, the length of fixed block group, effectively reach the full exhibition length of pulling out track.
