For achieving the above object, the technical solution adopted in the utility model is:
Self-return formula slide rail comprises outer rail 1, interior rail 2, and interior rail 2 is assemblied in the outer rail 1, and interior rail 2 is provided with microscler chute 3 along center line, is provided with slip draw piece 4 in the chute 3; Slip draw piece 4 whole wedge shapes, its head is slightly narrow, the width coupling of afterbody and chute 3, its afterbody also is provided with elastic traction part 5 and links to each other with the afterbody of chute 3, its head one side is laterally derived and is provided with fastener 41, the front end of chute 3 is provided with the holding portion 31 that cooperates with fastener 41 homonymies, and the head opposite side of slip draw piece 4 is provided with and colludes to portion 42, then is provided with on the outer rail 1 and colludes the brake component 11 that cooperates to portion 42; Interior rail 2 colludes to portion 42 when pulling out outer rail 1 and tangles brake component 11, and pull out slip draw piece 4 also with elastic traction part 5 common formation moments beat makes fastener 41 collude to portion 42 and discharge brake components 11 that slide rail is launched after hanging over holding portion 31 to holding portion 31; During interior rail 2 income outer rails 1 brake component 11 compress collude to portion 42 form moments with slip draw piece 4 beats away from holding portion 31, fastener 41 is broken away from collude to portion 42 after the holding portions 31 to tangle brake component 11 once more, under the back stretch effect of elastic traction part 5 with the slide rail self-return.In technique scheme, only need very little momentum just can guarantee that fastener 41 breaks away from holding portion 31 in the process that slide rail is regained, and under the back stretch effect of elastic traction part 5 with behind the slide rail self-return, launch slide rail once more and need overcome the elastic force of elastic traction part 5, from and reach prevent slide rail after inclination because of the unexpected effect that launches of gravity.
As improvement of the technical scheme, slip draw piece 4 also comprises the beat body 43 that is located at fastener 41 front ends, beat body 43 is provided with guiding surface 431 towards chute 3 center lines one side, slide rail launches back fastener 41 as failing to hanging over holding portion 31 because of accident, the moment that 11 of brake components overcome guiding surface 431 when regaining slide rail makes slip draw piece 4 near colluding to portion 42, forms again to collude to hang with it to cooperate.
As improvement of the technical scheme, beat body 43 has the elasticity bifurcated of ∧ type, and the bifurcated in the outside is derived from beat body 43 tops and formed, and inboard bifurcated is guiding surface 431.
As improvement of the technical scheme, collude to portion 42 and be the oblique groove at slip draw piece 3 tops, from a side direction angular direction is offered away from fastener 41.
As improvement of the technical scheme, brake component 11 is for riveting or be welded on the cylinder of outer rail 1 inner surface.
As improvement of the technical scheme, elastic traction part 5 is a metal spring.
Compared with prior art, the utlity model has following beneficial effect:
Structural principle is simple, low production cost, and its automatic resetting device added fault-tolerant correction structure, more perfect function, and operation has hommization; Slide rail only need rely on small momentum can self-return after, and launch slide rail once more and need overcome elastic traction part elastic force, reach prevent slide rail after inclination because of the unexpected effect that launches of gravity.
