Detailed description of the invention
Below with reference to accompanying drawing, the utility model will be further described, it should be noted that, the present embodiment, premised on the technical program, give detailed embodiment and concrete operating process, and protection domain of the present utility model is not limited to the present embodiment.
As shown in figs 1 to 6, a kind of buffer unit, comprise housing 1, the both sides at described housing 1 top are provided with two tracks 11, the middle part at housing 1 top is then provided with piston rod draw-in groove 12, be connected with the bar cylinder 2 of piston rod in piston rod draw-in groove 12 regularly, the body of rod 3 of piston rod is then arranged in bar cylinder 2 reciprocating motion also can done relative to bar cylinder 2; The two bottom sides of described housing 1 is provided with cavity 13, and its inside is fixedly connected with one end of spring 4.Number in the figure 14 and 15 represents the pilot hole of housing 1.
The front end of described piston rod draw-in groove 12 is fixedly connected with the rear end of extension rail 5, and the middle part at extension rail 5 top is provided with chute 51, and the front end of described chute 51 is hook-shaped groove 52, and the internal diameter at described hook-shaped groove 52 two ends is all a bit larger tham the internal diameter in the middle part of hook-shaped groove 52.
The front of described housing 1 arranges small slide block 6, and the bottom of described small slide block 6 is provided with the depressed part that matches with extension rail 5 and is connected on extension rail 5 slidably by depressed part; And the top of described small slide block 6 and track 11 set by housing 1 are provided with track 61 of plugging into accordingly; The two bottom sides of described small slide block 6 is provided with the cavity volume 62 corresponding with cavity 13 set by housing 1 two bottom sides, and the other end of described spring 4 is fixedly connected in described cavity volume 62.In addition, small slide block is provided with arcuate socket 63.
Space between described small slide block 6 and extension rail 5 is provided with metal rotation lock dog 7, form primarily of limiting plate 71, the upper prop 72 being fixed at limiting plate 71 top and bottom respectively and lower prop 73, described limiting plate 71 is rotatably connected to described small slide block 6, and number in the figure 64 represents this swivel joint; Described upper prop 72 to be embedded in arcuate socket 63 and can to do relative motion along arcuate socket 63, and lower prop 73 then can do relative motion along chute 51 and hook-shaped groove 52, and wherein, described lower prop 73 can just by the middle part of hook-shaped groove 52.
Described buffer unit also comprises the hook corresponding with metal rotation lock dog 7 and locks 8, is provided with arc-shaped recess screens 81 in described hook lock 8, and described arc-shaped recess screens 81 matches with upper prop 72 upper end of described metal rotation lock dog 7.Number in the figure 82 represents the pilot hole hooking lock 8.
Further, the body of rod 3 front end of described piston rod is provided with annular groove 31, and the end of described small slide block 6 is provided with the little cavity volume 65 with the piston rod body of rod 3 ends match, and in little cavity volume 65, be provided with the protrusion 66 matched with described annular groove 31, the front end of the body of rod 3 is accommodated in little cavity volume 65, and described protrusion 66 is rabbeted in described annular groove 31.
When buffer unit is installed, the housing of described buffer unit is embedded in the carriage base matched, and the slider bottom be slidably connected on base is embedded on track slidably, the described relevant position hooking lock and be then arranged on slide block.Now, the piston rod body of rod is in contraction state, and the upper prop upper end of metal rotation lock dog is connected in the arc-shaped recess screens hooking lock, and the end of small slide block contacts with the front end of housing, and spring is in original-shape.When slide block forward slip pulls open, upper prop due to metal rotation lock dog is connected to and hooks in lock, therefore small slide block is together driven forward slip by slide block, spring starts to stretch gradually, the body of rod of piston rod extends, until to rotate into the lower prop of metal rotation lock dog arrives the chute front end on extension rail in the lump during together with small slide block in hook-shaped groove and to be connected to the front end of hook-shaped groove, and to small slide block generation pulling force backward, now the upper prop of metal rotation lock dog leaves arc-shaped recess screens under pulling force effect backward, and slide block departs from small slide block continuation forward slip.
When skid closes, what when slide block slides backward and reaches extension rail front end, its two bottom sides entered small slide block plugs in track, and the upper prop of metal rotation lock dog reenters in the arc-shaped recess screens hooking lock, and under the drive hooking lock, metal rotation lock dog rotates gradually and departs from described hook-shaped groove, reenter in chute, slide backward in the lump with slide block, now, under the reply of spring and the contraction of the piston rod body of rod, slide block slowly enters in the track of buffer unit, finally achieves the effect of buffering.
For a person skilled in the art, according to above technical scheme and design, various corresponding change and distortion can be made, and all these change and distortion all should be included within the protection domain of the utility model claim.
