Abstract

The utility model relates to a self-closing buffering device used for the sliding rail of a drawer. The device comprises an upper rail and a lower rail, a sliding rail carriage fixedly installed on one side wall body at the front end of the lower rail, a spring installation block fixedly installed at a position a certain distance away form the sliding way carriage, a sliding groove formed along the length direction inner side the sliding way carriage, a sliding strip arranged in the sliding groove, a self-closing spring connected between the sliding strip and the spring installation block, a front limiting bench and a rear limiting bench which are formed at the top part of the sliding way carriage, an arc sliding rail bended downward formed at a position corresponding to the rear end of the sliding groove, a sliding block movably and axially connected on the sliding strip, a shifting strip matched with a concave pit and arranged at the front end of one side wall body corresponding to the upper rail, a top block arranged at the rear end of the side wall body, and a buffering device matched with the top block and arranged at the rear part of the lower rail. After adopting the technical proposal, when the drawer is closed, by utilizing the co-function of the self-closing spring and the buffering device, no matter how large closing force is made, the slow closing of the drawer can be guaranteed.

Description

A kind of buffer unit of pass certainly of drawer sliding rail

Technical field:

The utility model relates to the drawer guideway technical field, refers in particular to a kind of buffer unit of pass certainly of drawer sliding rail.

Background technology:

Drawer often takes place and does not close situation about just leaving fully in people when closing drawers, it is too little this situation to occur and might be the dynamics of closing, drawer is not closed fully, also might be that the dynamics of closing is too big, hard collision takes place, make drawer rebound out, make a noise simultaneously, now lack a kind of drawer that makes from the device that closes and produce buffering.

Summary of the invention:

The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, a kind of buffer unit of pass certainly of drawer sliding rail to be provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of buffer unit of pass certainly of drawer sliding rail, include rail and following rail, on a sidewall bodies of following rail front end, be fixed with slideway shelf, be fixed with the spring mounting blocks on the position apart from slideway shelf one segment distance, the inboard of this slideway shelf forms chute along its length, be placed with slider bar in the chute, be connected with between slider bar and the spring mounting blocks from closing spring, on the top of slideway shelf, form front limit platform and back limiting stand, and form the circular arc slide rail that turns round on the position of corresponding chute end downwards, movable axis is connected to slide block on slider bar, top at this slide block forms pit, front end forms last fixture block that cooperates with the front limit platform and the following fixture block that cooperates with the back limiting stand, and the rear end forms the slide guide post that cooperates with the slideway shelf top, and the front end on a sidewall bodies of last rail correspondence is provided with the bar of stirring that cooperates with pit, and the rear end is provided with jacking block, is provided with the buffer that cooperates with jacking block at the rear of following rail.

The rear that is positioned at pit on slide block forms and stirs the elasticity fixture block that bar cooperates.

After adopting technique scheme, when drawer is closed, utilize from the acting in conjunction of closing spring and buffer, no matter the dynamics size of closing, the assurance drawer is slowly closed.

Description of drawings:

Fig. 1 is the structural representation of drawer sliding rail;

Fig. 2 is the three-dimensional exploded view of drawer sliding rail;

Fig. 3 is that slideway shelf, slide block, slider bar, spring and spring installed part are assemblied in one structural representation;

Fig. 4 is the decomposing state schematic diagram of slideway shelf and slide block;

Fig. 5 is another schematic diagram of decomposing state of slideway shelf and slide block;

Fig. 6 is the three-dimensional exploded view of Fig. 3.

The specific embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

Shown in accompanying drawing 1～accompanying drawing 6, this drawer sliding rail is three rail structures, include rail 1, middle rail 2 and following rail 3, on a sidewall bodies of following rail 3 front ends, be fixed with slideway shelf 4, the inside spring mounting blocks 5 that on the position of slideway shelf 4 one segment distances, is installed with, the inboard of this slideway shelf 4 forms chute 6 along its length, be placed with slider bar 7 in the chute 6, be connected with between slider bar 7 and the spring mounting blocks 5 from closing spring 8, on the top of slideway shelf 4, form front limit platform 9 and back limiting stand 10, and form the circular arc slide rail 11 that turns round on the position of corresponding chute 6 ends downwards, movable axis is connected with slide block 12 on slider bar 7, slide block 12 can be rotated around slider bar 7, form pit 13 on the top of this slide block 12, front end forms last fixture block 14 that cooperates with front limit platform 9 and the following fixture block 15 that cooperates with back limiting stand 10, the rear end forms the slide guide post 16 that cooperates with slideway shelf 4 tops, slide block 12 can be in the top slide of slideway shelf 4 by slide guide post 16, when sliding into the circular arc slide rail 11 that turns round downwards, slide block 12 can rotate, on can changeing, blocks following fixture block 15 back limiting stand 10, front end on a sidewall bodies of last rail 1 correspondence be provided with cooperate with pit 13 stir bar 17, and the rear end is provided with jacking block 18, rear at following rail 3 is provided with the buffer 19 that cooperates with jacking block 18, the rear that is positioned at pit 13 on slide block 12 forms and stirs the elasticity fixture block 20 that bar 17 cooperates, lose mating reaction when stirring bar 17 with pit 13, be drawer be open but slide block 12 when being parked on the position of front limit platform 9, elasticity fixture block 20 with stir bar 17 and cooperate, pulling slide block 12 resets.

When pulling out drawer, stirring bar 17 is in the pit 13, driving slide block 12 travels forward, the motion bar 21 of buffer 19 stretches out simultaneously, when slide block 12 moved to the circular arc slide rail 11 that turns round downwards, under the acting in conjunction of stirring bar 17 and slide guide post 16, slide block 12 rotated, at this moment following fixture block 15 upwards produces and blocks back limiting stand 10, goes up rail and can move forward and open drawer up to being with fully.

During closing drawers, move to pit 13 positions when stirring bar 17, will drive slide block 12 rotates, fixture block 15 is rotated, at this moment from closing spring 8 effect pulling slider bars 7 and slide block 12 motion backward together, jacking block 18 withstands buffer 19 simultaneously, makes rail 1 motion backward slowly, drawer is closed automatically, blocks front limit platform 9 up to the last fixture block 14 of slide block 12.
