The specific embodiment:
See shown in Fig. 1 to 15, the utility model comprises outer rail 1, interior rail 2, roller support 3, take-up housing 4 and collision block 5, outer rail 1 and interior rail 2 are by 3 nested connections of roller support, and outer rail 1 and interior rail 2 are provided with the screens sheet that prevents roller support 3 landings, base plate 21 both sides of interior rail 2 are extended with track limit 22 and the fixed edge 23 perpendicular to base plate 21 respectively, and its middle orbit limit 22 bending formings have " T " font track 24; Roller support 3 main bodys become a rectangular bulk, and its inside offers the slot 31 that cooperates with " T " font track 24, and roller support 3 is located on the track 24 of interior rail 2 by slot 31; Outer rail 1 is a body that does not seal, and it is set on the roller support 3; The upper surface of roller support 3 equidistantly offers roller slot 32, two sides equidistantly offer ball grooves 33 respectively, roller slot 32 is placed with roller 321, be placed with ball 331 in the ball grooves 33, the interior upper wall surface of the upper surface of track 24 and outer rail 1 contacts with roller 321, and two medial surfaces of the two sides of track 24 and outer rail 1 contact with ball 331 respectively.
The base plate 21 of interior rail 2 offers the fixedly locating slot 211 of take-up housing 4, take-up housing 4 two ends offer respectively and locating slot 211 corresponding stopper slots 41, take-up housing 4 is fastened in the locating slot 211 by the stopper slot 41 at two ends, take-up housing 4 offers chute 42, the spring 6 that is provided with collision block 5 in the chute 42 and collision block 5 is resetted, collision block 5 is provided with the slide block 51,52,54 that is positioned at chute 42, spring 6 is positioned at chute 42, and its two ends are connected on the slide block 52 of projection 421 in the chute 42 and collision block 5; In chute 42 relatively an end of projection 421 offer match with slide block 51 collude groove 422; Collision block 5 offers draw-in groove 53 in a side of outstanding chute 42, and the side of outer rail 1 is fixed with the outer rail collision block 7 that cooperates with draw-in groove 53.
Workpiece principle: under normal circumstances, collision block 5 is in initial state under the effect of spring 6, outer rail collision block 7 on the outer rail 1 is positioned at draw-in groove 53 at this moment, when external force F pulling outer rail 1, and this tensile force f is during greater than the elastic force of spring 6, outer rail 1 will produce relative slippage with interior rail 2, and collision block 5 also will move with outer rail 1 under the drive of outer rail collision block 7 simultaneously; When the slide block 51 of collision block 5 moves to when colluding groove 422 along chute 42, collision block 5 is under the pressure of outer rail collision block 7, its side will be depressed into and collude in the groove 422, its slide block 51 also will be pressed into and collude in the groove 422, and slide block 51 inlay cards are in colluding groove 422, be that collision block 5 is defined to this, this moment, spring 6 was in the state of being stretched; When collision block 5 be depressed into collude in the groove 422 after, collision block 5 deflects immediately, the draw-in groove 53 on it also deflects simultaneously, the outer rail collision block 7 on the outer rail 1 just breaks away from draw-in groove 53 like this, outer rail 1 no longer is subjected to the restriction of collision block 5, can move freely; After outer rail 1 back promotes certain distance, outer rail collision block 7 falls in the draw-in groove 53 once more, collision block 5 turns round under the effect of outer rail collision block 7, be that slide block 51 breaks away from and colludes groove 422 and fall into chute 42 again, at this moment, collision block 5 broken away from collude the qualification of groove 422 to it after, under the effect of the pulling force of spring 6, reset rapidly, simultaneously, outer rail 1 back slides onto original position under the drive of outer rail collision block 7.
The utility model can be used in the various facilities, for example in the drawer of furniture, during use, outer rail 1 and interior rail 2 are fixed with drawer and desk respectively, and like this, not only the folding of drawer is very smooth suitable during use, and drawer has the function that can close automatically, makes things convenient for the user to the full extent.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
