Abstract

The utility model supplies a fastener used for tire of automobile with decorating sleeve, namely a wheel lock with decorating sleeve used for wheel rim of automobile. The utility model comprises a core body of the fastener used to fasten the wheel rim of the tire of automobile like a nut or a bolt and the decorating sleeve fixed out of the core body with a concave and convex structure arranged at peripheral of the decorating sleeve. A matched wrench is used when loosening, thus enhance safety and avoid steel of tire of automobile effectively. Meanwhile, because the decorating sleeve can be processed to be aluminum alloy decorating sleeve with many colors, decorating effect is obtained and more additional function and value is endowed to the conventional fastener.

Description

The motor tire fastener that has the decorations cover

Technical field

The utility model relates to a kind of secure component, relates in particular to a kind of fastener of the motor tire that is used to lock, and is characterized in having the decorations cover, not only can be antitheft but also have a decorative effect.

Background technology

All be provided with the fastening nut or the bolt of the hexagon (or other shapes) more than at least three on the wheel rim of most automobiles, this fastener the wheel rim that purpose is the locking motor tire (being called as the wheel lock) is set.But this fastener uses the ordinary cartridge spanner to be relaxed easily, thereby causes tire to lose, particularly some expensive luxury cars, burglar assistant's target especially.So it is very necessary researching and developing a kind of fastening wheel lock construction element that can play antitheft effect simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of motor tire fastener that has the decorations cover at the problems referred to above, by a sheathed decorations cover outside the fastening nut of orthodox car wheel rim or bolt, make the lax of nut or bolt reach the purpose of locking motor tire by special wrench.

The motor tire that has the decorations cover that the utility model provides comprises that with fastener one is used for fastener core body and decorations cover that is fixed in outside this core body of the wheel rim of affixed motor tire, and the outside of this decorations cover is provided with concaveconvex structure.

Wherein, the exterior concaveconvex structure of this decorations cover comprises groove or protruding key, can be rule or irregular setting.

According to the technical solution of the utility model, this fastener core body is fastening nut or bolt; Be provided with the polygon endoporus in the decorations cover, core body then has a polygon head that can coincide with it.

According to the technical solution of the utility model, described decorations cover can be fixed in the outside or the exposed end of core body, and core body is affixed with welding or bonding mode with the decorations cover, also can be aided with other connection mode and be strengthened affixed.

According to the technical solution of the utility model, this core body can be made by metallic materials such as iron and steel, the aluminum alloy materials of decorations cover for painting, or other mechanical strength well also can be processed the material of colouring.

The utility model provides this motor tire fastener that has the decorations cover must use when lax and adorns and overlap the spanner that exterior groove or protruding key match, can turn, and can effectively avoid the quilt of motor tire to steal, thereby improve safety factor.Simultaneously,, also have decorative effect, make this conventional fasteners be endowed more additional function and value because this decorations cover can be processed into assistant with multicoloured aluminum alloy decorations cover.

Description of drawings

Fig. 1 is the cutaway view of nut type fastening wheel lock of the present utility model.

Fig. 2 is the cutaway view of screw bolt-type fastening wheel lock of the present utility model.

Specific embodiments

Describe enforcement of the present utility model and characteristics thereof in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 has shown the nut type fastening wheel lock of motor tire wheel rim of the present utility model, it comprises nut core body 1 and its outer sheathed decorations cover 2, this decorations cover 2 preferably adopts quality is slim and graceful, mechanical strength is good aluminum alloy or other alloy material and colorable material to make colored decorations cover, and 1 in core body preferably adopts materials such as iron and steel.

This nut core body 1 has an internal thread hole 11, and for being combined on the wheel rim of motor tire, the bolt (not shown) that axle hub was connected with, its outer end is set as hexagon or has hexagonal head 12.

Decorations cover 2 of the present utility model is preferably the cylindrical shape of aluminum alloy material, purpose is to be convenient to make colored decorations cover by surface treatment (anodizing), its inside is provided with polygon (hexagon) 21, match with the hexagonal head 12 of nut core body 1, the periphery of this decorations cover 2 is concaved with irregular groove 22.

Screw nut and during the loading, unloading tire at need, must be by a socket wrench of unblanking to use of specially joining, be provided with the protruding key that can coincide with groove 22 in the sleeve of this spanner, with just rotatable, lax each nut behind the decorations cover fit, change, the operation of mount tyre.

Figure 2 shows that screw bolt-type fastening wheel lock, bolt core body 1 has outside thread 11a and polygon (as hexagon) head 12, and decorations cover 2 has corresponding polygon endoporus 21, and the outside also is provided with groove 22.

Between core body 1 among Fig. 1 and Fig. 2 and the decorations cover 2 can be that flush fit is affixed, but also mat welding or adhesive agent bonding make it affixed more firm.

Decorations cover 2 of the present utility model can be an aluminum alloy material, be easy to carry out surface treatment like this, has multicolour through processing and fabricating, and then give decorative effect, do not influence simultaneously the good mechanical properties of core body iron and steel material quality again, and cost greatly reduces than whole bolt or the nut of all making with aluminum alloy, so have practical economic value.

For saving the material of decorations cover 2, can add this decorations cover 2 of cover in principle from the outer end of this core body 1 (or exposed end) and get final product, and needn't make the whole enclosures of decorations cover encase whole core body 1.

The outside of above-mentioned decorations cover 2 can be provided with groove 22, can also be set as the protruding key (not shown) of rule or fitfull, at this moment, unblanks need be arranged to and the corresponding groove of this protruding key with the endoporus of socket wrench.

The above is only making detailed explanation by specific embodiment to design plan of the present utility model, but the utility model does not add restriction to shape, structure, the material of this fastener, so any application design concept of the present utility model, the design by suitable modification, variation and using all should be included in the practical range of the present utility model.
