Description
Technical field
The utility model relates to a kind of screw, particularly relates to a kind of screw that prevents slippage.
Background technique
At present, being used for element part and tightening up a screw, is to be meshed together by internal thread and outside thread by screw and nut to constitute.Such screw comes off easily, when especially using on automobile, because automobile vibration is bigger and time of vibration is longer, just is more prone to come off.The same position that also has plenty of at screw and nut has a hole, inserts a pin in the hole, and bolt can prevent effectively that screw from coming off, and such shortcoming is punched exactly to insert again and sold cumbersome.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned existing screw, and a kind of screw that prevents slippage is provided.
For achieving the above object, the utility model is realized by following technical measures:
A kind of screw that prevents slippage, by can intermeshing screw 1 and nut 2 constitute, it is characterized in that, have nut overcoat 3 to be enclosed within the outside of described nut 2, described screw 1 end has segment groove 4 vertically, and along the circumferential direction there are all draw-in grooves 5 described nut 2 front end outsides, the big protruding block 6 that projection is arranged on described nut overcoat 3 inner wall at end, on described nut overcoat 3 front inner wall small lugs 7 is arranged, described big protruding block 6 may be stuck in the described axial groove 4, and described small lugs 7 may be stuck in the described draw-in groove 5.
The beneficial effects of the utility model: can effectively prevent coming off of nut, and after the nut overcoat taken off, can adjust the position of nut and fix with the nut overcoat again, avoid the trouble of punching.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Specific embodiment one
The screw that prevents slippage of the present utility model please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 5, and it includes screw 1, nut 2 and nut overcoat 3.Among Fig. 1, the right-hand member of screw 1 is the end of screw 1, and the left end of nut 2 is the front end of nut 2 among Fig. 2, and among Fig. 3, the right-hand member of nut overcoat 3 is the end of nut overcoat 3.The end of screw 1 has segment axial groove 4 vertically, and along the circumferential direction there are all draw-in grooves 5 the front end outside of nut 2, on nut overcoat 3 inner wall at end big protruding block 6 is arranged, and on described nut overcoat 3 front inner wall small lugs 7 is arranged.During use, earlier nut 2 and screw 1 are tightened, and are made the end of screw 1 stretch out the end of nut 2, and make big protruding block 6 be stuck in the axial groove 4 and along axial groove 4 to screw 1 nose motion, nut overcoat 3 is enclosed within the outer end of nut 2 the most at last.At this moment, small lugs 7 is stuck in the draw-in groove 5, because there is the effect of frictional force to make nut overcoat 3 not fall down outside nut 2, an end of big protruding block 6 is stuck in the axial groove 4, make nut overcoat 3 and screw 1 not to relatively rotate, and then guaranteed that nut 2 can be from slippage on the screw 1.In addition, small lugs 7 can have a plurality of, and the number of small lugs 7 is many more, and frictional force is big more, and nut overcoat 3 is difficult more to fall down outside nut 2.
Specific embodiment two
The screw that prevents slippage of the present utility model, please refer to Fig. 4 and Fig. 5, can also be that in the specific embodiment one other are constant, just the external shaft of nut 2 is to being evenly distributed with multistage straight trough 8, and with 8 pairs of straight troughs multistage raised line 10 should be arranged on the inwall of nut overcoat 3, straight trough 8 can fasten mutually with raised line 10.The arrangement of straight trough 8 and corresponding raised line 10 is all than comparatively dense, and big protruding block 6 can have certain elasticity.During use, earlier nut 2 and screw 1 are tightened, and the end that makes screw 1 stretches out the end of nut 2, and make big protruding block 6 be stuck in the axial groove 4 and along axial groove 4 to screw 1 nose motion, guarantee the raised line 10 corresponding fastenings of straight trough 8 and nut overcoat 3 on the nut 2 simultaneously, nut overcoat 3 is enclosed within the outside of nut 2.Because straight trough 8 has certain elasticity with the arrangement of raised line 10 than comparatively dense and big protruding block 6, so can guarantee straight trough 8 and raised line 10 corresponding fastenings, big protruding block 6 is stuck in the axial groove 4.Because straight trough 8 and raised line 10 engagements guarantee that nut 2 is tightr with combining of nut overcoat 3, screw 1 can not relatively rotate with nut overcoat 3, and it is better to make that nut 2 combines with screw 1, nut 2 more difficult slippages.
Specific embodiment three
The screw that prevents slippage of the present utility model, please refer to Fig. 1, can also be that in specific embodiment one and the specific embodiment two other are constant, just axial groove 4 and big protruding block 6 be more than two and at described screw 1, nut 2 and nut overcoat 3 each big protruding block 6 of back be installed and be may be stuck in each axial groove 4 corresponding with it.Like this, make nut 2 tightr, more be difficult for slippage with combining of screw 1.
Specific embodiment three
The screw that prevents slippage of the present utility model, please refer to Fig. 3, Fig. 4 and Fig. 5, can also be that other of specific embodiment one and specific embodiment two are constant, just the outer wall at nut overcoat 3 has projection 9, like this, projection 9 has been convenient for people to Point of Strength the nut overcoat is installed more effortlessly or disassembles when installation or removal.
