Abstract
The present invention is a kind of self lock nut and bolt, it comprises nut and bolt main body, friction spring, relief holes, awl end alleviation screw, described self lock nut and bolt utilize the elasticity of friction spring, indirectly the engagement and the frictional force principle, with plain bolt (cap) secure fit the time, play self-locking, anti-loosening effect, be applicable to variously run up, industrial field such as machinery of judder, vehicle, facility and have certain anti-loosening anti-dismounting effect.
Description
The present invention relates to a kind of fastening piece, particularly a kind of self lock nut and bolt.
Common standard nut or bolt are running up, under the alternate load of judder, impact loading, loosening are mainly adopting spring washer, the cotter pin of retaining punching and to measures such as top nuts for what prevent fastening screw.And spring washer and only can play certain locking lock function when the tightening state to the top nut but be unable to undergo long vibratory impulse, under strong alternate load, impact loading, connect and loosening phenomenon often occurs, especially spring washer or cotter pin fracture occur very big gap so that fully loose or dislocation lose fastening effect, bring about great losses.
The invention provides a kind of self lock nut and bolt, purpose and be intended to solve fastening nut, the bolt problem of loose or dislocation easily under aforementioned user mode, and create a kind of do not tightening or loosening situation under can only tighten the using effect that can not unscrew, more can oneself not come off.
Described self-locking nut bolt is made of main body 1, friction spring 2, relief holes 3, tapered alleviation screw 4.It is characterized in that: friction spring 2 and main body 1 be gapped mutually to mesh together and the fixed gap 5 of the fixed end 7 of friction spring 2 and main body 1 fixes, the movable end 6 of friction spring 2 place main body 1 waist (or root) relief holes 3 places and alleviate screw 4 with relative remission hole, 45 ° of inclined-planes 3, awl end and place in the relief holes 3.(interior) directly 9 promptly outside plain bolt (cap) that needs cooperate in interior (outward) of friction spring 2 footpath smaller (greatly): the diameter of described friction spring 2, and when being bolt for main body 1, its external diameter is greater than the internal diameter of the nut that matches mutually with it; When being nut for main body 1, its internal diameter is less than the external diameter of the bolt that matches mutually with it.Its characteristics of principle is: from the fixed end 7 of friction spring 2 screw clockwise, overlap (button) go up at plain bolt with matching (cap) () time, since external force and the frictional force that is produced push up mutually (drawing), to make friction spring body increasing diameter (subtracting) greatly (little), make friction spring 2 with plain bolt (cap) thus line or face contact the frictional force that produces and reduce and can screw in smoothly.Otherwise, (increasing) little (greatly) that then diameter of friction spring subtracted, friction spring frictional force that the line or the face contact of plain bolt (cap) produced increases, is enough to plain bolt (cap) that hoop (opening) tightly matches, makes it and can not withdraw from.
The invention has the advantages that: be skillfully constructed, simple for structure, can remove spring washer from, to additional accessories such as top lock nuts, reduce maintenance cost, reduce and consume, improve working life and safety reliability and have certain anti-dismounting and tamper-proof effect, can realize the large-scale standardized producing in serial form.
Description of drawings and embodiment:
Fig. 1 is the structure principle chart of one of self-locking nut bolt body of the present invention nut.1 is that nut body, 2 is that friction spring, 3 is that relief holes, 4 is that fixed gap, 6 is movable end, 7 fixed ends for boring end alleviation screw, 5 among the figure.
Fig. 2 is the structure principle chart of two bolts of nut and bolt main body of the present invention.Number in the figure is same as in figure 1,1 be that bolt body, 2 is alleviated screw, 5 for relief holes, 4 for the awl end for friction spring, 3 and is fixed end for movable end, 7 for fixed gap, 6 among the figure.
Described nut and bolt is the same with the plain nut bolt when assembling is used, be screwed into afterwards spanner conveniently tightens and gets final product.Need dismounting or when adjusting, the awl ends in the relief holes 3 are alleviated movable end 6 that screws 4 push away (drawing) friction spring 2, increased (subtracting) big (little), alleviated frictional force that hoop (opening) effect of friction spring 2 produced, just removed locking or self-locking, therefore realized dismounting or adjustment to the integral diameter that makes friction spring 2 with flat mouthful of spiral shell cutter.Friction spring 2 in the described nut and bolt can correspond to single head and bull by the number of leads of the bolt nut that matches mutually with it; And the number of friction spring 2 can be single, also can be a plurality of being superimposed upon simultaneously.It can be multiple as prismatic, rectangle, ellipse garden shape or the like that the geometrical shape that constitutes friction spring 2 material sections requires according to purposes and varying strength, and its diameter can not wait yet.
Claims (5)
1, a kind of self lock nut and bolt, comprise main body 1, friction spring 2, it is characterized in that: the interior outer screw thread of the main body 1 of described nut and bolt is local or all meshing friction spring 2 with a gap, the fixed end 7 of friction spring 2 fixes with the fixed gap 5 of main body 1, and the movable end 6 of friction spring 2 places on the main body 1 in the relief holes 3.
2, nut and bolt according to claim 1 is characterized in that: the geometrical shape of the transverse section of described formation friction spring 2 materials is according to purposes and varying strength requires to prismatic, ellipse garden shape, rectangle and can be anisodiametric.
3, nut and bolt according to claim 1, it is characterized in that: the diameter of described friction spring 2, when being bolt for main body 1, its external diameter is greater than the internal diameter of the nut that matches mutually with it, when being nut for main body 1, its internal diameter is less than the external diameter of the bolt that matches mutually with it.
4, nut and bolt according to claim 1, it is characterized in that: described friction spring 2 is divided into single head and bull by the number of leads correspondence of the bolt nut that matches with it.
5, nut and bolt according to claim 1, it is characterized in that: the number of the friction spring 2 on the described main body 1 can be single, also can a plurality ofly be superimposed upon simultaneously.
