Abstract
The utility model discloses a sliding door device for achieving a buffer and an automatic closing, which comprises a buffer equipped on the slide rail of a sliding door and a control assembly equipped on the top of the sliding door. The buffer comprises a narrow long rectangular groove body. The upper part of the rectangular groove body adjacent to one end is fixedly provided with a small cylinder with a piston rod which is connected with one end center of a hook connecting block. The upper part of the connecting end is a block which is correspondingly separated with a side lying T-shaped block equipped on the upper part of the other end of the hook connecting block. The block in the upper part of the connecting end and the T-shaped block form a concave bucking port. The bottom of the hook connecting block is provided with a return spring. And the two side central parts of the hook connecting block are both provided with a limiting short column. The rectangular groove body two side parts which are as high as the limiting short columns are provided with a bar-shaped hollow sliding chute with a slightly larger diameter than the limiting short column diameter. The sliding chute starts from the aligning place of the rectangular groove central part and the block in the upper part of the connecting end and then to the T-shaped block and last extends to the end of the rectangular groove body. The above structure of the utility model can eliminate the harsh door-closing sounds due to the buffer effects to the door. Furthermore, the utility model can achieve automatic complete door closing due to the pulling effects from the small cylinder and the return spring.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The front view of snubber when Fig. 1 opens for sliding door;
Fig. 2 is the front view that links piece;
Fig. 3 is the vertical view that links piece;
Fig. 4 is the front view of Control Component.
The specific embodiment
Referring to Fig. 1, Fig. 4, provide a kind of sliding door to realize buffering and the device of closing automatically, it comprises snubber 1 that is installed on the sliding door rail and the Control Component 2 that is installed in the sliding door top.
Referring to Fig. 1-Fig. 3, described snubber 1 comprises long and narrow rectangle cell body 3, rectangle cell body 3 tops are near its left end, be fixed with the small oil tank 5 of band piston rod 4, piston rod 4 links to each other with the left end middle part that links piece 6, the top of this link is block 7, and itself and T shape piece 8 relative spacings of lying on one's side in the right-hand member top that links piece 6 form spill bayonet socket 9; The upper surface of T shape piece 8 is the inclined plane, the upper endpiece 10 relative on the T shape piece 8 with block 7, and crossbearer is above rectangle cell body 3 dual-sides; Link piece 6 bottoms and be connected with back-moving spring 11, back-moving spring 11 is positioned at the bottom of rectangle cell body 3, the below of small oil tank 5, and the left end of back-moving spring 11 is fixed on the end of rectangle cell body 3; The middle part, two sides that links piece 6 is equipped with spacing short column 12, on rectangle cell body 3 dual-sides with spacing short column 12 with high position, be provided with the bar shaped that highly is slightly larger than spacing short column 12 diameters and wear empty chute 13, it aligns initial from rectangle cell body 3 middle parts with block 7, along block 7 to T shape pieces 8 directions, extend end to rectangle cell body 3, and chute 13 transfers little skewed slot 14 to when extending to afterbody; Little skewed slot 14 anterior position, the top of rectangle cell body 3 dual-sides also all transfers big skewed slot 15 to.
Referring to Fig. 4, Control Component 2 comprises bearing 17, spring base 18 and piston pushing block 19, the three is the convex piece, bearing 17 top hollows wherein, and the bottom is provided with opening 20, spring base 18 top hollows, upwards insert bearing 17 from opening 20, piston pushing block 19 bottoms also are provided with opening 21, are provided with regulating spring 22 between the opening 21 of the opening 20 of bearing 17 bottoms and piston pushing block 19 bottoms, the top of piston pushing block 19 is surrounded by wear-resisting gum cover 23, and wear-resisting gum cover 23 tops are connected with semicircular noise elimination ball 24.
When Control Component 2 was installed in the sliding door top, regulating spring 22 was scalable, thus the differing heights that Control Component 2 is adapted between sliding door top and the slide rail.The effect of wear-resisting gum cover 23 is to avoid the piston pushing block of metal 19 directly to contact repeatedly with the piece 6 that links of rubber, increases parts application life.Noise elimination ball 24 makes piston pushing block 19 tops only with less contact point contact slide rail bottom, can avoid directly contacting the slide rail bottom because of the entire upper surface of piston pushing block 19, and produce bigger noise.
When sliding door is closed condition, piston pushing block 19 by fastening in spill bayonet socket 9, when needing to open sliding door, promote sliding door to the right, piston pushing block 19 promotes to link piece 6 and slides to the right along rectangle cell body 3, this moment, back-moving spring 11 was stretched gradually, and piston rod 4 is pulled out small oil tank 5 gradually, and spacing short column 12 slides along chute 13.When spacing short column 12 slides to little skewed slot 14 tops, link piece 6 lower tilt to the right, spacing short column 12 falls into little skewed slot 14 bottoms and blocks, T shape piece 8 also falls into big skewed slot 15 and blocks, link piece 6 and promptly be stuck motionlessly, piston pushing block 19 is then selected spill bayonet socket 9, and this moment, sliding door can be continued to promote smoothly to the right to open, and can not be subjected to the obstruction of spill bayonet socket 9, realize complete opening until sliding door.
When sliding door is opening, spacing short column 12 fastenings are in little skewed slot 14 bottoms, T shape piece 8 also fastening in big skewed slot 15, in the time of need closing sliding door, promote sliding door left, Control Component 2 slides left with sliding door, and piston pushing block 19 slips in the spill bayonet socket 9, promote block 7, make spacing short column 12 skid off little skewed slot 14, slide left along chute 13, T shape piece 8 skids off big skewed slot 15, slide left along rectangle cell body 3, this moment, piston rod 4 also began to reset with back-moving spring 11, to linking the pulling force that piece 6 produces left, because piston rod 4 can only slowly reset in small oil tank 5, the speed that sliding door is slided left obtains buffering, no matter the user is firmly much, and sliding door all can be releived, realize reposefully closing fully, just contact gently with the doorframe side frame, can eliminate ear-piercing sound at closing time fully, more can not rebound.And, till the user does not need door to be shifted onto always and closes, only need touch and can loose one's grip, and Men Zehui is subjected to the tension of piston rod 4 and back-moving spring 11, continues automatic realization and closes fully.
Referring to Fig. 1, chute 13 bottoms of rectangle cell body 3 dual-sides all have L shaped bent mouthful 16 near place, small oil tank 5 ends.Spacing short column 12 presses down mobilizable little of L shaped bent mouthful 16 tops when sliding into above in the of L shaped bent mouthful 16 left along chute 13, the slip that links piece 6 is descended highly slightly, and helping sliding, balance is smooth and easy more.
The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
