The specific embodiment

As Fig. 2～shown in Figure 11, the buffer structure of the self closing device of a kind of side locking type drawer sliding rail of the utility model, wherein this self closing device system includes:

Slide 1, tie up to its bottom and have draw-in groove 111,112 nested bindings of convex clip (figure does not show) that can be shaped with the bottom face institute integrated punching of the external slide rail 21 of drawer sliding rail 2 or link with this external slide rail 21 bottom faces with locking or other modes are fixed, this external slide rail 21 then is other mat lock member (figure does not show) and the side locking of the madial wall of cabinet (figure does not show) links, this slide 1 has a sliding ditch 10, the wall of the both sides adjacent symmetric in this cunning ditch 10 has unidirectional chute 101, and the top at the position, stage casing of chute 101 forms stop surface 102, front side then bending downwards extends to form clamping groove 1012, and the rear side of this slide 1 has draw-in groove 103 and can be convenient to the opposite side 302 of spring 30 and collude and set the position in addition;

Slide block group 3, system include sliding collude 31 with slide block 32, wherein to collude 31 be a left side to this cunning, before the right both sides, after respectively symmetry have frong guide column 311 and BB1 312, can be hubbed in the set chute 101 of the adjacent wall in both sides in the sliding ditch 10 of slide 1, making this cunning collude 31 can reciprocatingly slide at the sliding ditch 10 of slide 1, and its front side has the guiding incline 313 to the front lower place inclination, then has detent 314 near the middle part, its top has block 315 in addition, and cunning is colluded 31 back side-line and slide block 32 pivot joints, the both sides of this slide block 32 have location hook 321 can be for being connected with a side 301 of spring 30, and the opposite side 302 by this spring 30 is connected with slide 1 again;

Trace 221 (with reference to figure 4) is a side of being located in the drawer sliding rail 2 end face of the interior slide rail 22 that the lateral wall locking with drawer (figure does not show) links, and the inboard of this trace 22 connects slotted eye 222;

Composition by aforementioned components, the cunning of slide block group 3 is colluded the stop surface 102 of the sliding ditch 10 that 31 block 315 tyings are blocked in slide 1 (with reference to figure 6 in the time of in off position, Fig. 7, Fig. 8), the trace 221 of interior slide rail 22 then is positioned at sliding 31 the detent 314 of colluding (with reference to figure 5, Fig. 7), trace 221 interlock cunnings collude 31 when drawer is pulled outwardly together with interior slide rail 22, make this cunning collude its frong guide column 311 of 31 mats and the chute 101 backward slippage of BB1 312 along work slide 1, when sliding onto the front side of chute 101, frong guide column 311 can fall into its clamping groove 1012 downwards, be upturned and make this cunning collude 31 rear sides, the frong guide column 311 of front side then is positioned at this clamping groove 1012 (with reference to figure 9, Figure 10), the trace 221 of slide rail 22 can break away from and slidingly colludes 31 detent 314 (in addition with reference to Figure 10) and can continue slippage forward and in making; Otherwise, when drawer together with interior slide rail 22 backward during the reversion original position, the preceding side contacts cunning of this trace 221 is colluded 31 front sides and is entered its detent 314 and lean the rear surface 3151 of the adjacent block 315 of this detent 314 backward along its guiding incline 313 of work, can make this cunning collude 31 front side is upturned, the frong guide column 311 of its front side can make progress slippage and break away from the location of this clamping groove 1012 along clamping groove 1012 with season, and with can be by the elasticity reversion strength of the slide block 32 set springs 30 of slide block group 3 back side slip to chute 101, make sliding collude 31 block 315 backstops in the stop surface 102 of slide 1 (with reference to figure 6, Fig. 7, Fig. 8), reach automatic closing function;

It is characterized in that:

This slide 1, cording has the locating slot 12 (with reference to figure 8) can be for being embedded or locking or other modes are installed an oil hydraulic cylinder 4, the axle center 41 of this oil hydraulic cylinder 4 then have caulking groove 411 can for 32 set inlay card 322 (with reference to figure 8) nested connections of slide block of slide block group 3, and then when the cunning of slide block group 3 collude 31 with slide block 32 by the elasticity strength of spring 30 backward during the reversion slippage, but the oil pressure resistance that the axle center 41 of mat oil hydraulic cylinder 4 withdrawal oil hydraulic cylinder bodies 40 are produced and reduce slide block group 3 speed of reversion slippage backward, make relatively drawer that slide block group 3 and interior slide rail 22 linked backward the speed of reversion slippage also slow down and have a cushioning effect, preventing that drawer from producing violent shake backward during the reversion slippage, and also have relatively and can reduce noise and reduce the advantage that member damaged and improved service life.

Again, it is that rear side has pivot connected slot 310 (with reference to Figure 11) and can articulate for the pivot 320 with slide block 32 that the cunning of aforementioned Slide Group 3 colludes 31, slidingly colludes 31 by the smoothness of the trace 221 interlock slippages of interior slide rail 22 to keep.

In addition, the locating slot 12 of aforementioned slide 1 is to be communicated with its sliding ditch 10, and oil hydraulic cylinder body 40 peripheries of aforesaid oil hydraulic cylinder 4 then have fixture block 401 with in the nested locating slot 12 that is positioned aforementioned slide 1.

Again, with reference to shown in Figure 4, the drawer sliding rail 2 of previous embodiment is the syllogic drawer sliding rail of being made up of members such as interior slide rail 22, middle slide rail 20 and external slide rails 21, and same feature also can apply to the two-part drawer sliding rail be made up of members such as interior slide rail and external slide rails, does not give unnecessary details in addition at this.

In addition, the utility model system makes the axle center of oil hydraulic cylinder connect the slide block group to reach pooling feature applicable to the self closing device of the different structure of side locking type drawer sliding rail so long as have slide, spring and can all can be installed oil hydraulic cylinder at slide by the slide block group of the trace interlock of interior slide rail.

In sum, the utility model can be concluded and be had following enhancement effect:

1. by slide 1 oil hydraulic cylinder 4 is set at self closing device, the axle center 41 of this oil hydraulic cylinder 4 then is connected with slide block group 3, and then have cushioning effect during slippage backward automatically together with drawer, and then can avoid shake, reduce noise when the elasticity reversion strength of slide block group 3 mat springs 30.

2. because self closing device has cushioning effect, relatively also can reduce member and damage, improve service life, and also have the advantage that assembly easily, must not installed complicated buffer gear additional.
