Abstract
The utility model provides a self-locking slide rail for a drawer, which is composed of a fixed slide rail and at least one movable sliding rail which can slide along fixed slide rails, wherein one end of the fixed slide rail is provided with a shifting fork, and both sides of the shifting fork is provided with a pull-out shifting sheet and a push-in shifting sheet; one end of the shifting fork is connected with the fixed slide rail in a hinging way; the fixed slide rail on both ends of the shifting fork is provided with a spacing block; a torsion spring is arranged between the shifting fork and the fixed slide rail. One end of the torsion spring is connected with the fixed slide rail, and the other end is arranged at the middle part of the shifting fork; a shifting block is arranged near the end part of the movable slide rail corresponding to the shifting fork. The utility model can effectively prevent the automatic outward slide of a drawer and can realize the self-locking purpose of the drawer.
Description
Technical field
The utility model relates to a kind of drawer sliding rail, but is meant a kind of drawer sliding rail of self-locking especially.
Background technology
Traditional drawer slide rail, generally be one limited block to be set in the end of fixed rack, the one rubber folder that is mated is set on movable slide rail, utilize the rubber folder to clamp limited block and prevent that drawer from outwards skidding off, because of rubber presss from both sides the influence that is subject to temperature, service time, aging distortion, reduce chucking power, can not play the purpose that prevents that drawer from skidding off automatically, special in relatively large file cabinet, result of use is poorer.The present inventor has proposed a kind of technical scheme that addresses the above problem through scrutinizing, and can prevent effectively that drawer from outwards skidding off automatically, and by installing and using, effect is very good.
Summary of the invention
But being to provide a kind of, the purpose of this utility model can prevent effectively that drawer from outwards skidding off, realizing the drawer sliding rail of the self-locking of drawer self-locking automatically.
But the purpose of this utility model is achieved in that a kind of drawer sliding rail of self-locking, can form along the movable slide rail that this fixed rack slides by fixed rack and at least one, wherein: an end of described fixed rack is provided with shift fork, the shift fork both sides are provided with pulls out plectrum and pushes plectrum, and an end and the fixed rack of this shift fork are articulated and connected; Be provided with limited block on the fixed rack on shift fork both sides, be provided with the button spring between shift fork and fixed rack, an end of button spring is connected with fixed rack, and the other end is arranged on the shift fork middle part; Be provided with shifting block at the movable slide rail close end corresponding with shift fork.
After the utility model adopts said structure, by end one shift fork and button spring are set at fixed rack, the shifting block of utilization activity slide rail close end is stirred shift fork, when needs outwards during pulling activity slide rail, must overcome the elastic force of button spring, movable slide rail could be pulled out, by the elastic force size of button spring rationally is set, can prevent effectively that drawer from outwards skidding off automatically, reach the self-locking purpose after drawer pushes.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the view of the movable slide rail of the utility model when pulling out;
Fig. 2 is the view of the movable slide rail of the utility model when pushing self-locking;
Fig. 3 is the perspective view of shift fork in the utility model.
The specific embodiment
As shown in Figure 1 to Figure 3, but the drawer sliding rail of self-locking of the present utility model, the transition slide rail 5 and the movable slide rail 2 that slide by fixed rack 1, along this fixed rack 1 are formed, one end of fixed rack 1 is provided with shift fork 3, shift fork 3 both sides are provided with pulls out plectrum 31 and pushes plectrum 32, one end and the fixed rack 1 of this shift fork 3 are articulated and connected, and are equipped with limited block 11 on the fixed rack 1 on shift fork 3 both sides, are used for limiting the slewing area of shift fork 3; Be provided with button spring 4 between shift fork 3 and fixed rack 1, an end of button spring 4 is connected with fixed rack 1, and the other end is arranged on shift fork 3 middle parts; Be provided with shifting block 21 at movable slide rail 2 close ends corresponding with shift fork 3.
When the utility model specifically uses, fixed rack 1 is fixed on the cabinet, movable slide rail 2 is fixedlyed connected with drawer, when pushing drawer, what the shifting block 21 of movable slide rail 2 close ends withstood shift fork 3 pushes plectrum 32, overcomes the elastic force of button spring 4, shift fork 3 is rotated, after shift fork 3 rotating certain angle, the elastic force of button spring 3 makes shift fork 3 contact with the limited block 11 in the outside, at this moment, pulling out plectrum 31 contacts with shifting block 21, under the elastic force effect of button spring 3, movable slide rail 2 is locked, presents state shown in Figure 2.When pulling out drawer, the shifting block 21 extruding shift forks 3 of movable slide rail 2 close ends pull out plectrum 31, overcome the elastic force of button spring 4, shift fork 3 is rotated, after shift fork 3 rotating certain angle, the elastic force of button spring 3 makes shift fork 3 contact with the limited block 11 of inboard, at this moment, can smoothly drawer be pulled out, present state shown in Figure 1.
