Abstract
The utility model discloses a locknut, include: the nut comprises a nut body and a washer, wherein a screw hole is formed in the nut body, a hole expanding hole which is coaxial with the screw hole and has a diameter larger than that of the screw hole is formed in one end of the nut body, an elastic conical rubber ring is arranged in the hole expanding hole, an annular protrusion corresponding to the elastic conical rubber ring is arranged on the axial inner end face of the washer in a protruding mode, the cross section of the annular protrusion is in a right trapezoid shape, the annular protrusion moves upwards to extrude the elastic conical rubber ring, and a plurality of annular check rings are arranged on the bottom face of the washer. In this way, the utility model provides a lock nut extrudees elasticity toper rubber ring through the annular arch on the packing ring for elasticity toper rubber ring forms friction fit with the bolt, effectively prevents that the nut body from the pine phenomenon of taking off appearing after the assembly.
Description
Technical Field
The utility model relates to a nut field especially relates to a locknut.
Background
The nut is a part for tightly connecting mechanical equipment, and the nut and the bolt with the same specification can be connected together through the threads on the inner side.
Currently, nuts are on the market, which comprise a nut body. Although traditional nut simple structure, in the occasion of some vibrations, nut and bolt cooperation back take place to become flexible easily to influence the firm degree of installation.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a locknut to solve the problem that exists among the background art.
In order to solve the technical problem, the utility model discloses a technical scheme be: provided is a locknut, including: the nut comprises a nut body and a washer, wherein a screw hole is formed in the nut body, a hole expanding hole which is coaxial with the screw hole and has a diameter larger than that of the screw hole is formed in one end of the nut body, an elastic conical rubber ring is arranged in the hole expanding hole, an annular protrusion corresponding to the elastic conical rubber ring is arranged on the axial inner end face of the washer in a protruding mode, the cross section of the annular protrusion is in a right trapezoid shape, the annular protrusion moves upwards to extrude the elastic conical rubber ring, and a plurality of annular check rings are arranged on the bottom face of the washer.
In a preferred embodiment of the present invention, the cross-section of each annular retainer ring is trapezoidal.
In a preferred embodiment of the present invention, the diameter of the elastic conical rubber ring is larger than the diameter of the screw hole.
In a preferred embodiment of the present invention, the inclined surface of the elastic tapered rubber ring is in contact with the inclined surface of the annular protrusion.
In a preferred embodiment of the present invention, the elastic conical rubber ring is made of rubber.
The utility model has the advantages that: the utility model discloses a locknut who points out extrudees elasticity toper rubber ring through the annular arch on the packing ring for elasticity toper rubber ring forms friction fit with the bolt, prevents effectively that the nut body from appearing the pine phenomenon of taking off after the assembly.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a schematic structural view of a preferred embodiment of a locknut of the present invention.
Detailed Description

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention includes:
a locknut, comprising: nut body 1 and packing ring 2, be provided with screw 3 on the nut body 1, the one end of nut body 1 is provided with and is greater than reaming 4 of screw 3 coaxial and diameter with screw, be provided with elasticity toper rubber ring 5 in the reaming 4, the axial inner end face epirelief of packing ring 2 is provided with the annular arch 6 that corresponds with elasticity toper rubber ring 5, the cross-section of annular arch 6 is right trapezoid, the protruding 6 rebound of annular extrudees elasticity toper rubber ring 5, be provided with a plurality of annular retaining rings 7 on the bottom surface of packing ring 2.
The section of each annular retainer ring 7 is in a trapezoidal shape. The diameter of the elastic conical rubber ring 5 is larger than that of the screw hole 3. The inclined plane of the elastic conical rubber ring 5 is contacted with the inclined plane of the annular bulge 6. The elastic conical rubber ring 5 is made of rubber.
To sum up, the utility model discloses a locknut who points out extrudees elasticity toper rubber ring through the annular arch on the packing ring for elasticity toper rubber ring forms friction fit with the bolt, effectively prevents that the nut body from the pine phenomenon of taking off appearing after the assembly.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
