Description

A kind of vehicle anti-theft bolt
Technical field
The utility model belongs to auto-parts field, particularly a kind of vehicle anti-theft bolt.
Background technique
China is an automobile superpower, and the recoverable amount of annual automobile is all constantly increasing fast, and the tire of automobile belongs to one of component be easily stolen, and reason is that clamping bolt used is all conventional stud, is often very easily just removed.
Model utility content
For solving defect of the prior art, the utility model provides a kind of vehicle anti-theft bolt, and this anti-theft bolt by easy removal, can not have certain anti-theft feature.
Technological scheme:
A kind of vehicle anti-theft bolt, comprises bolt body and threaded stem; Described bolt body is fixed on described threaded stem top; To having nose bar bottom described bolt body, described nose bar outer wall is provided with outside thread, is arranged with brute spring outside described nose bar; Described threaded stem top is outwards provided with annular boss, and described annular boss is inwardly provided with the interior threaded hole corresponding with described nose bar outside thread, is provided with bottom thread bottom described threaded stem, and the bottom of described interior threaded hole is to having interior hexagonal shrinkage pool.
Described bolt body lower surface is distributed with 4-6 projection.
Described bolt body is six column structures.
Described brute spring adopts chromium alloyed steel material.
Technique effect:
The utility model provides a kind of vehicle anti-theft bolt, and compared to the prior art, the utility model has following beneficial effect:
After bolt body is disassembled by people, annular boss and threaded stem are also in fastened state, and must put in the interior hexagonal shrinkage pool of rotation in interior threaded hole by special tool could dismantle by double thread bar, and chek bolt has now possessed anti-theft effectively.
Be arranged with brute spring outside nose bar by the anti-loosening property of bolt body can be promoted with the active force of annular boss simultaneously.
Bolt body is fixed on described threaded stem top by thread engagement, and the projection that bolt body lower surface is arranged also further can increase frictional force, prevents getting loose of bolt body.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vehicle anti-theft bolt in the utility model;
Fig. 2 is the structural representation of bolt body in Fig. 1.
In figure, each label example is as follows:
Hexagonal shrinkage pool, 9-projection in 1-bolt body, 2-brute spring, 3-threaded stem, 4-annular boss, 5-bottom thread, 6-nose bar, 7-interior threaded hole, 8-.
Embodiment
Fig. 1 is the structural representation of a kind of vehicle anti-theft bolt in the utility model; Fig. 2 is the structural representation of bolt body in Fig. 1.
Shown in Fig. 1 and Fig. 2, a kind of vehicle anti-theft bolt disclosed in the utility model, comprises bolt body 1 and threaded stem 3; Bolt body 1 is fixed on threaded stem 3 top; To having nose bar 6 bottom bolt body 1, nose bar 6 outer wall is provided with outside thread, brute spring 2 is arranged with outside described nose bar 6, threaded stem 3 top is outwards provided with annular boss 4, annular boss 4 is inwardly provided with the interior threaded hole 7 corresponding with nose bar 6 outside thread, makes bolt body 1 be fixed on threaded stem 3 top by thread engagement.Be provided with bottom thread 5 bottom threaded stem 3, the bottom of interior threaded hole 7 is to having interior hexagonal shrinkage pool 8.
Bolt body lower surface is distributed with 4-6 projection.Projection 9 further can increase frictional force, prevents getting loose of bolt body 1.
In the present embodiment, preferred projection 9 quantity is 6, is evenly distributed on the lower surface of bolt body 1.
Further, bolt body 1 is six column structures.Conveniently dismantled by Wrench, structure is simple, convenient operation.
Described brute spring adopts chromium alloyed steel material, and ballistic properties is good.
Concrete, after bolt body 1 is disassembled by people, annular boss 4 and threaded stem 3 are also in fastened state, and must put in the interior hexagonal shrinkage pool 8 of rotation in interior threaded hole 7 by special tool could dismantle by double thread bar 3, and chek bolt has now possessed anti-theft effectively.Be arranged with brute spring 2 outside nose bar 6 by the anti-loosening property of bolt body 1 can be promoted with the active force of annular boss 4 simultaneously.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
