Abstract
The utility model discloses a tire bolt which comprises a bolt body, a cushion ring sleeved on the bolt body and a locking nut. An elastic connection ring is clamped between the cushion ring and the locking nut. Two axial end faces of the elastic connection ring are concave arc faces. The end face, contacted with one axial end of the elastic connection ring, of the cushion ring is a convex arc face of the cushion ring. The end face, contacted with the other axial end of the elastic connection ring, of the locking nut is a convex arc face of the nut. As the elastic connection ring, the cushion ring and the locking nut are matched as the arc faces are matched, the contacted faces among the elastic connection ring, the cushion ring and the locking nut are enlarged and stress bearing is even. Meanwhile, under the condition that threads of the locking nut are not standard, bending force will not be exerted on the bolt body and safety risks can be eliminated as the locking nut can automatically carry out alignment through sliding of the matched arc faces of the locking nut and the elastic connection ring.
Description
Technical field
The utility model relates to a kind of tire bolt, relates in particular to a kind of tire bolt nut assembly.
Background technique
At present, existing tire bolt normally is made of bolt body and the packing ring and the locking nut that are set on the bolt body, and be connected for plane contact between packing ring and the locking nut, such structure is provided with and causes the surface of contact of the end face that contacts between packing ring and the locking nut less, stressed too concentrated easily.Simultaneously existing tire bolt structure also can't solve and cause the surface of contact injustice because of the screw thread of locking nut is nonstandard, thereby bolt body is produced bending power, causes the bolt body easy-rupturing, has potential safety hazard.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of using effect better tire bolt.
For achieving the above object, the utility model provides a kind of tire bolt, comprise bolt body, and be set in packing ring and locking nut on the bolt body, clamp flexible fastener rings between described packing ring and the locking nut, the axial two ends end face of described elasticity fastener rings is the indent arc shaped surface, on the described packing ring with the elasticity fastener rings axially wherein the contacted end face of an end be packing ring evagination arc shaped surface, the contacted end face of the axial the other end with the elasticity fastener rings on the described locking nut is a nut evagination arc shaped surface, the outer ring surface of described elasticity fastener rings is a spherical arc, the inner ring surface middle part of described elasticity fastener rings is provided with a groove, described packing ring and the contacted end face of elasticity fastener rings are provided with the packing ring extension block that extends to elasticity fastener rings groove direction, and the end of described packing ring extension block is provided with described groove one side and constitutes the packing ring barb that hook is joined, described locking nut and the contacted end face of elasticity fastener rings are provided with the nut extension block that extends to elasticity fastener rings groove direction, and the end of described nut extension block is provided with the nut barb of joining with described groove another side formation hook.
The beneficial effects of the utility model are: adopt said structure, because the utility model has been set up the elasticity fastener rings between described packing ring and locking nut, and be the arc shaped surface contact matching between described elasticity fastener rings and packing ring, the locking nut, therefore can increase its surface of contact each other, make stressed more even, simultaneously, under the nonstandard situation of the screw thread of locking nut, the arc shaped surface slip automatic capturing that can cooperatively interact by itself and elasticity fastener rings, thereby avoid bolt body is produced bending power, eliminate safe hidden trouble.In addition, the outer ring surface of described elasticity fastener rings adopts spherical arc, can avoid stress to concentrate on the elasticity fastener rings, improves total bearing capacity; On the inner ring surface of described elasticity fastener rings, groove is set, and the packing ring barb and the nut barb of joining with the corresponding hook of described groove be set on described packing ring and locking nut, after assembling is finished, packing ring, elasticity fastener rings and locking nut can combine, prevent mutual disengaging, further improve total bearing capacity.
The utility model can further be set to be coated with wear-resistant material layer on the axial two ends indent arc shaped surface of described elasticity fastener rings, and the thickness of described wear-resistant material layer is 0.5 ~ 3.5mm.
Adopt said structure, on the indent arc shaped surface of described elasticity fastener rings, set up wear-resistant material layer, can improve the working life of elasticity fastener rings.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial structurtes exploded view of the present utility model.
Embodiment
As Fig. 1, provided a kind of tire bolt shown in 2, comprise bolt body 1, and be set in packing ring 2 and locking nut 3 on the bolt body 1, clamp flexible fastener rings 4 between described packing ring 2 and the locking nut 3, the axial two ends end face of described elasticity fastener rings 4 is indent arc shaped surface 41, on the described packing ring 2 with elasticity fastener rings 4 axially wherein the contacted end face of an end be packing ring evagination arc shaped surface 21, the contacted end face of the axial the other end with elasticity fastener rings 4 on the described locking nut 3 is a nut evagination arc shaped surface 31, because described elasticity fastener rings 4 and packing ring 2, it between the locking nut 3 the arc shaped surface contact matching, therefore can increase its surface of contact each other, make stressed more even, simultaneously, under the nonstandard situation of the screw thread of locking nut 3, the arc shaped surface slip automatic capturing that can cooperatively interact by itself and elasticity fastener rings 4, thereby avoid bolt body 1 is produced bending power, eliminate safe hidden trouble.The outer ring surface 42 of described elasticity fastener rings 4 is a spherical arc, inner ring surface 43 middle parts of described elasticity fastener rings 4 are provided with a groove 431, described packing ring 2 is provided with the packing ring extension block 22 that extends to elasticity fastener rings groove 431 directions with elasticity fastener rings 4 contacted end faces, and the end of described packing ring extension block 22 is provided with described groove 431 1 sides and constitutes the packing ring barb 221 that hook is joined, described locking nut 3 is provided with the nut extension block 32 that extends to elasticity fastener rings groove 431 directions with elasticity fastener rings 4 contacted end faces, and the end of described nut extension block 32 is provided with the nut barb 321 of joining with described groove 431 another sides formation hook.In addition, also be coated with wear-resistant material layer 5 on the axial two ends indent arc shaped surface 41 of described elasticity fastener rings 4, and the results showed, preferred 0.5 ~ the 3.5mm of the thickness of described wear-resistant material layer 5, preferred 0.3 ~ the 2mm of the degree of depth of groove 431 on the described elasticity fastener rings 4, described packing ring extension block 22 and nut extension block 32 extend axially the preferred 3 ~ 8mm of length, when adopting above-mentioned data, the whole service life of tire bolt is the longest.
