Traditional drawer as desk, strongbox, file cabinet, Tool Cabinet, tote-box or the like, but all possesses the drawer that level is extracted out or pushed basically.In order can to pull out easily or to push, generally can a pair of movable slide rail be set in the both sides of drawer, comparatively speaking, it is easy to use, laborsaving that the drawer that has added movable slide rail is compared the drawer that does not have slide rail, and closure effect is good.
Yet, on reality was used, following point often took place.First kind be drawer when pushing too energetically, eject a bit of distance again after bumping against the bottom; Second kind to be that drawer pushes power slightly little, slack when the bottom, and drawer can't be fastened fully, leaves the sub-fraction drawer and expose; The third is not a flat dip, earthquake or when suffering external force collision, drawer can skid off of ground, the locking that can't put in place, and these three kinds of problems all make us perplexing.
The utility model content
The purpose of this utility model is to address the aforementioned drawbacks, and provides a kind of rational in infrastructure, locking effect stable, durable slide rail locking device.
For achieving the above object:
Slide rail locking device, comprise slide rail, locking device is installed on the slide rail, locking device comprises pedestal, have chute on the pedestal, be provided with locating piece in the chute and fasten slide block, locating piece places the end of chute, and locating piece is provided with lock pin, lock pin protrudes from the locating piece surface, described fastening shoe surface is provided with projection and button piece, fastens the slide block bottom surface and has unidirectional guide groove, fastens slide block and chute front end and is connected with back-moving spring.
Described locating piece one end has the installation through hole, and the installation through hole that bolt passes locating piece is connected with the end of chute, and lock pin is plugged on the other end of locating piece.
The bottom surface of described fastening slide block has and forms fixture block in the unidirectional guide groove, fastens slider side wall and is provided with guide pad.
The chute both sides of described pedestal have gathering sill, the guide pad of the above-mentioned fastening slide block of gathering sill support.
The beneficial effects of the utility model:
The utility model is equipped with locking device in the slide rail of drawer, locking device comprises pedestal, has chute on the pedestal, is provided with locating piece in the chute and fastens slide block, locating piece places the end of chute, locating piece is provided with lock pin, and lock pin protrudes from the locating piece surface, and described fastening shoe surface is provided with projection and button piece, fasten the slide block bottom surface and have unidirectional guide groove, form fixture block in the unidirectional guide groove, fasten slide block and chute front end and be connected with back-moving spring, this is rational in infrastructure.
Slide rail is divided into outer, interior slide rail, during use, and the pushing block of slide rail in being installed in, the projection that promotes on the slide block slides along chute, slides to slide when putting locating piece, and the lock pin of locating piece enters the unidirectional guide groove of slide rail bottom surface, slide along unidirectional guide groove, lock pin is buckled on the fixture block of unidirectional guide groove, realizes locking slide rail, sliding rail again, lock pin breaks away from the fixture block of unidirectional guide groove, lock pin skids off along unidirectional guide groove, and slide block breaks away from locating piece, and the realization slide rail pushes away to be stretched.Such locking effect is stable, makes slide rail durability height.

The specific embodiment
As shown in Figures 1 to 3: slide rail locking device, comprise slide rail, locking device is installed on the slide rail, locking device comprises pedestal 1, have chute 2 on the pedestal 1, be provided with locating piece 3 in the chute 2 and fasten slide block 4, locating piece 3 places the end of chute 2, and locating piece 3 is provided with lock pin 301, lock pin 301 protrudes from locating piece 3 surfaces, described fastening slide block 4 surfaces are provided with projection 401 and button piece 402, fasten slide block 4 bottom surfaces and have unidirectional guide groove 403, fasten slide block 4 and are connected with back-moving spring 5 with chute 2 front ends.
Described locating piece 3 one ends have the installation through hole, and the installation through hole that bolt passes locating piece 3 is connected with the end of chute 2, and lock pin 301 is plugged on the other end of locating piece 3.
The bottom surface of described fastening slide block 4 has in the unidirectional guide groove 403 and forms fixture block 405, fastens slide block 4 sidewalls and is provided with guide pad 404.
Operation principle: slide rail is divided into outer, interior slide rail, during use, and the pushing block of slide rail in being installed in, the projection that promotes to fasten on the slide block 4 slides along chute, slides to slide when putting locating piece, and the lock pin of locating piece enters the unidirectional guide groove of slide rail bottom surface, slide along unidirectional guide groove, lock pin is buckled on the fixture block of unidirectional guide groove, realizes locking slide rail, sliding rail again, lock pin breaks away from the fixture block of unidirectional guide groove, lock pin skids off along unidirectional guide groove, fastens slide block 4 and breaks away from locating piece, and the realization slide rail pushes away to be stretched.Such locking effect is stable, makes slide rail durability height.
As shown in Figure 4: unidirectional guide groove 403 is provided with A portion, B portion, C portion, D portion, E portion; The lock pin 301 of locating piece 3, slide along unidirectional guide groove 403, lock pin 301 enters from unidirectional guide groove 403 inlets, and lock pin 301 slides into A portion and enters the F groove, and the F groove withdraws from, lock pin 301 withstands in B portion can't return it, make its button bit that enters fixture block 405, be buckled on the fixture block 405, at this moment, lock pin 301 lockings that fastening slide block 4 is positioned piece 3 realize the slide rail locking; Promote to fasten slide block 4 again, lock pin 301 breaks away from the button bit of fixture block 405, slides into C portion, and the inclination angle of C portion makes lock pin 301 enter the G groove, the G groove withdraws from, lock pin 301 withstands in D portion can't return it, makes it skid off unidirectional guide groove 403, when lock pin 301 skids off, E portion makes it put back original position, locating piece resets, and realizes the slide rail release, and slide rail can be free to slide.
