Description

Dust protected tire nut

Technical Field

The utility model relates to a dust protected tire nut belongs to tire nut field.

Background

The existing tire nut capable of being disassembled and assembled for many times is screwed, and because the tire nut capable of being disassembled and assembled for many times can generate certain deformation, a gap exists between a limiting disc of the tire nut and a screw hole, so that dust is easy to permeate, and subsequent screwing-out work is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a not enough to prior art exists, the utility model aims at providing a dust protected tire nut to solve the tire nut of current dismouting a lot of after screwing, because the tire nut can produce certain deformation many times of dismouting, there is the clearance between the restriction dish of tire nut can and the screw, leads to the infiltration of dust easily, influences the problem of subsequent work of screwing out.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a dust protected tire nut, its structure includes the nut body, nut body middle part is equipped with loose ring, spacing dish from top to bottom in proper order, the loose ring adopts the nested mode of sliding to be connected with the nut body, nut body upper portion is equipped with rotating-structure, nut body lower part is equipped with the internal thread groove, spacing dish upper end is equipped with the annular thread groove, loose ring lower part screw in annular thread groove, spacing dish bottom surface is equipped with a plurality ofly and the communicating arc of annular thread groove stretches out the hole, the loose ring lower extreme is equipped with the elasticity dustproof sheet that stretches into the arc and stretches out the hole.

Furthermore, the limiting disc and the nut body are of an integrated structure.

Further, the plurality of arc-shaped protruding holes form an annular structure.

Furthermore, the elastic dustproof sheet is of an arc-shaped structure.

Further, the cross section of the rotating structure is a regular hexagon.

The utility model has the advantages that: after the nut body is screwed, the movable ring is rotated clockwise for sixty degrees, so that the lower part of the movable ring is abutted against the limit of the annular thread groove bottom of the limiting disc, in the rotating process, the elastic dustproof sheet at the lower end of the movable ring is twisted, and because the elastic dustproof sheet is of an arc-shaped structure, the elastic dustproof sheet can be stretched out from the bottom of the limiting disc in the twisting process, and the gap between the limiting disc and the screw hole is blocked, thereby effectively playing a dustproof role.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, 2 and 3, the present invention provides a technical solution of a dustproof tire nut: its structure includes nut body 1, 1 middle part of nut body is equipped with loose ring 2, spacing dish 3 from top to bottom in proper order, loose ring 2 is connected with the nested mode of nut body 1 adoption slip, 1 upper portion of nut body is equipped with revolution mechanic 4, 1 lower part of nut body is equipped with interior thread groove 5, 3 upper ends of spacing dish are equipped with annular thread groove 6, 2 lower part screw in annular thread grooves 6 of loose ring, 3 bottom surfaces of spacing dish are equipped with a plurality ofly and the communicating arc of annular thread groove 6 and stretch out hole 7, 2 lower extremes of loose ring are equipped with the elasticity dustproof piece 8 that stretches into the arc and stretch out hole 7, spacing dish 3 and nut body 1 structure as an organic whole, and a plurality of arcs stretch out hole 7 and enclose into an annular structure, elasticity dustproof piece 8 is the arc structure, 4 cross sections of revolution mechanic are regular hexagon.

For example, after nut body 1 screwed, clockwise rotation activity ring 2 sixty degrees for the restriction is supported with 6 bottoms of the annular thread groove of spacing dish 3 in the 2 lower parts of activity ring, rotating the in-process, the elasticity dustproof sheet 8 of activity ring 2 lower extreme twists, and because elasticity dustproof sheet 8 is the arc structure, elasticity dustproof sheet 8 can be stretched out by spacing dish 3 bottom in the distortion process, carry out the shutoff to the clearance between spacing dish 3 and the screw, the effectual dustproof effect that plays.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
