Description
Technical field
The utility model is related to auto-parts technical field, specifically provides a kind of round tooth bolt.
Background technology
Bolt of the prior art mainly includes the bolt shank of round bar shape and is integrally connected to the axial one end of bolt shank
On bolt head, when bolt is installed on when on component, for erection ＆ lift tightness, it will usually bolt with it is to be installed
Multiple pads etc. are assembled between parts, which not only adds production cost, and to bolt, pad and install parts it
Between installation accuracy require high；In addition, even if being provided with pad sometimes, bolt is also easily made loosening, phenomenon of spinning occur, tightly
Solidity is poor.
In view of this, it is special to propose the utility model.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of round tooth bolt, and its simple in construction, quality is high, installs
Tightness is good.
The utility model is to solve the technical scheme that its technical problem is used：A kind of round tooth bolt, including round bar
The bolt shank of shape and the torus shape flange being connected on the axial one end of the bolt shank, the torus shape flange
With the integral forging molding of the bolt shank, and coaxial line；
Circular row is provided with multiple limited blocks on the periphery wall of the torus shape flange in addition, in the bolt shank
It is also formed with outer peripheral face along on its axially extending thread segment, and the thread segment and axially another close to the bolt shank
The screw thread of one end is round thread.
As further improvement of the utility model, radially extension is formed on the periphery wall of the torus shape flange
There is a circle fin, the plurality of limited block circular row is arranged on the fin.
As further improvement of the utility model, the fin is close to axial one end of the bolt shank；
The plurality of limited block is symmetric around the axis of the torus shape flange.
As further improvement of the utility model, thread locking adhesive is also coated with the thread segment of the bolt shank.
As further improvement of the utility model, also wrapped on the outer peripheral face of bolt shank and torus the shape flange
It is covered with one layer of zinc-nickel alloy layer.
The beneficial effects of the utility model are：Compared to bolt arrangement of the prior art, circle described in the utility model
Tooth bolt has bolt shank and is integrally connected to torus shape flange on the axial one end of the bolt shank, when by described in
When circle tooth bolt is installed in the installation screw of auto parts and components, torus shape flange can be turned over and closely be coated on automobile zero
On the installation screw of part, then coordinate multiple limited blocks being arranged on torus shape flange periphery wall, can effectively prevent circle
There is loosening, phenomenon of spinning in tooth bolt, and installs tightness good；In addition, the round tooth bolt is when in use, it is not necessary to additionally use
The parts such as pad, so as to reduce production cost.
Brief description of the drawings
Fig. 1 is the cross-sectional view at the round visual angle of tooth bolt one described in the utility model；
Fig. 2 is the cross-sectional view at round another visual angle of tooth bolt described in the utility model.
With reference to accompanying drawing, make the following instructions：
1 --- bolt shank 2 --- torus shape flange
3 --- limited block 4 --- thread locking adhesives
Embodiment
Preferred embodiment of the present utility model is described in detail referring to figure.
Embodiment：
Refer to shown in attached Fig. 1 and 2, the section knot of two different visual angles of round tooth bolt respectively described in the utility model
Structure schematic diagram.The round tooth bolt includes the bolt shank 1 of round bar shape and is connected on the axial one end of the bolt shank 1
And be pressed on the torus shape flange 2 on auto parts and components to close bag, bolt shank 1 and torus the shape flange 2 by
Steel alloy material is made, the torus shape flange 2 and the integral forging molding of the bolt shank 1, and coaxial line；
Circular row is provided with multiple limited blocks 3 on the periphery wall of the torus shape flange 2 in addition, when circle tooth bolt is installed
When on auto parts and components, the limited block can effectively prevent that justifying tooth bolt spins, and plays spacing, fastening effect, described
It is also formed with the outer peripheral face of bolt shank 1 along on its axially extending thread segment, and the thread segment and close to the spiral shell
The screw thread of the axial other end of bolt stem 1 is the round thread of dome round bottom shape, can prevent inclined tooth in bolt assembling process, play
Correcting is acted on, beneficial to the installation of circle tooth bolt.
In the present embodiment, it is preferred that radially extension is formed with a circle on the periphery wall of the torus shape flange 2
Fin, the plurality of circular row of limited block 3 is arranged on the fin.
It is further preferred that the fin is close to axial one end of the bolt shank 1；The plurality of limited block 3 is surrounded
The axis of the torus shape flange 2 is symmetric.
In the present embodiment, thread locking adhesive 4 is also coated with the thread segment of the bolt shank 1, such as uses 3M2510
Blue thread locking adhesive, meets sealing demand.
In the present embodiment, also it is coated with one layer of zinc-nickel on the outer peripheral face of bolt shank 1 and torus the shape flange 2
Alloy-layer, improves the rust-resisting property of bolt product.
The installation method of round tooth bolt described in the utility model is：First, the correcting effect of round thread is used, will be described
Circle tooth bolt is quickly bolted in the installation screw of auto parts and components (in the installation screw of such as automotive window), then again to described
Torus shape flange carries out turning over operation, it is closely coated on the installation screw of auto parts and components.
In summary, compared to bolt arrangement of the prior art, round tooth bolt described in the utility model has bolt
Bar portion and torus shape flange on the axial one end of the bolt shank is integrally connected to, is installed on when by the round tooth bolt
When in the installation screw of auto parts and components, torus shape flange can be turned over and be closely coated on the installation screw of auto parts and components
On, then coordinate multiple limited blocks being arranged on torus shape flange periphery wall, can effectively prevent from justifying tooth bolt and occur loosening,
Spin phenomenon, tightness is installed good；In addition, the round tooth bolt is when in use, it is not necessary to extra to use the parts such as pad, from
And reduce production cost.
