Abstract
The utility model discloses a locknut for an automobile. The locknut comprises a nut and a flange gasket, wherein a conical nut closed opening is arranged under the nut; a gasket through hole is arranged at the lower end of the flange gasket and communicated with a conical hole of the flange gasket above the gasket through hole, the conical hole of the flange gasket is conical and corresponds to the nut closed opening, and the conical degree of the conical hole of the flange gasket is larger than that of the nut closed opening; the cone base of the nut closed opening is larger than that of the conical hole of the flange gasket, and the cone vertex of the nut closed opening is smaller than that of the conical hole of the flange gasket; a tensioning groove is arranged on the nut closed opening; and at least two extensible grooves are evenly arranged at the lower end of the nut closed opening. The locknut utilizes the conical degree clamp locking theory, when the nut is screwed, the nut closed opening having the conical degree is radially compressed due to the effect of the extensible grooves, and the nut can be firmly fixed on a bolt, so that the shortcoming that the traditional nut is easy to loose under vibration is overcome, and normal usage and safety performance of automobiles can be guaranteed.
Description
Technical field
The utility model relates to technical field of automobile components, is specifically related to a kind of for the lock nut on automobile.
Background technique
When more abominable, the wheel nut of vehicle, track bar nut, U bolt nut etc. due to the congenital structure deficiency of loosening, are easy to become flexible, and greatly reduce the use function of vehicle, and have potential safety hazard when road conditions and loading conditions.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly is difficult for loosening, being dismounted for multiple times and can reduce the automobile-used lock nut that loosens performance.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of automobile-used lock nut is characterized in that: comprise nut and flange packing ring, the nut lower end is provided with nut crimping, and it is conical that nut crimping is; Flange packing ring lower end is the packing ring through hole, and the packing ring through hole is communicated with the flange packing ring cone shape hole of its top, and flange packing ring cone shape hole is the taper corresponding with nut crimping, and the tapering of the cone shape hole of flange packing ring is greater than the tapering of nut crimping; Large at the bottom of cone than flange packing ring cone shape hole at the bottom of the cone of nut crimping, the vertex of a cone of nut crimping is less than the vertex of a cone of flange packing ring cone shape hole; Nut crimping is provided with the tensioning groove, makes the thickness attenuation of nut crimping upper end, and the closing in dynamics is reduced; The nut crimping lower end evenly is provided with the flexible grooving of twice at least, and during nut crimping, stretchable sheet comes closer, and when nut unscrewed, stretchable sheet was to the both sides resilience.
Further, described nut and nut crimping are structure as a whole, and adopt one-body molded making.
Further, large 3 degree of the tapering of the taper ratio nut crimping of flange packing ring cone shape hole.
Working principle: utilize tapering fixture locking principle, when nut screwing clamping, the rate taper nut that has closes up because of the effect generation radial compression of flexible grooving, is converted into the interference fit state by the Spielpassung state, makes nut be locked on bolt securely.
The utility model is owing to having utilized tapering fixture locking principle, when nut screwing clamping, the rate taper nut that has closes up because of the effect generation radial compression of flexible grooving, make nut be locked in securely on bolt, it loosens reliable performance, being dismounted for multiple times and can not reduce and loosen performance has overcome conventional nut to be easy under the vibrations condition from loose defective, makes the normal use of automobile and Safety performance obtain larger guarantee.

Embodiment
In the present embodiment, with reference to Fig. 1, Fig. 2 and Fig. 3, described automobile-used lock nut comprises nut 1 and flange packing ring 2, and nut 1 lower end is provided with nut crimping 3, and nut crimping is 3 taper shapes; Flange packing ring 2 lower ends are packing ring through hole 6, and packing ring through hole 6 is communicated with flange packing ring 2 cone shape holes of its top, and flange packing ring 2 cone shape holes are the taper corresponding with nut crimping 3, and the tapering of the cone shape hole of flange packing ring 2 is greater than the tapering of nut crimping 3; Large at the bottom of cone than flange packing ring 2 cone shape holes at the bottom of the cone of nut crimping 3, the vertex of a cone of nut crimping 3 is less than the vertex of a cone of flange packing ring 2 cone shape holes; In the present embodiment, nut crimping 3 is bored the end than the packing ring through hole 6 cone large 1.2mm in the end, and nut crimping 3 vertex of a cones are than the flange packing ring 2 little 1.9mm of the vertex of a cone; Nut crimping 3 is provided with tensioning groove 5, makes the thickness attenuation of nut crimping 3 upper ends, and the closing in dynamics is reduced; Nut crimping 3 lower ends evenly are provided with the flexible grooving 4 of twice at least, and when nut 1 closes up, stretchable sheet comes closer, and when nut 1 unscrewed, stretchable sheet was to the both sides resilience.
Described nut 1 is structure as a whole with nut crimping 3, adopts one-body molded making.
Large 3 degree of the tapering of the taper ratio nut crimping 3 of flange packing ring 2 cone shape holes, the angle before closing up as nut crimping in the present embodiment 3 is 60 degree, is 63 degree after closing in.
Working principle: utilize tapering fixture locking principle, when nut 1 was tightened, the rate taper nut that has 3 effects because of flexible grooving 4 of closing up produced radial compression, are converted into the interference fit state by the Spielpassung state, make nut 1 be locked on bolt securely.
Below the utility model is described in detail, the above is only the preferred embodiment of the utility model, does not limit the utility model practical range, be allly to do impartial change and modify according to the application's scope, all should still belong in the utility model covering scope.
