In order to overcome drawbacks described above, the utility model provides a kind of stud, 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 stud, including it is coaxial
Line and the first integral screw rod, back-up ring, blocking circle, limiting section, polished rod and the second screw rod is linked in sequence, wherein, the gear
Circle and blocking circle are disc structure, and the limiting section has the body of a cylindrical shape, and on the outer surface of the body
Also circular row is provided with multiple arcs cutting face.
As further improvement of the utility model, the external diameter of the back-up ring is more than the external diameter of the blocking circle, and described
The axial width of the axial width of back-up ring and the blocking circle is unequal.
As further improvement of the utility model, each arc milling face is along the axially extending of the body.
As further improvement of the utility model, the arc milling face is six, and six arc milling faces
Axis around the body is symmetric.
As further improvement of the utility model, first screw rod screw thread dorsad on a shaft end of the back-up ring,
And screw thread of second screw rod dorsad on a shaft end of the polished rod is round thread.
As further improvement of the utility model, first screw rod, back-up ring, blocking circle, limiting section, polished rod and second
One layer of zinc layers are all coated with the outer surface of screw rod respectively.
The beneficial effects of the utility model are：Compared to prior art, stud described in the utility model have with
Lower advantage：1. special circumstances are more suitable in the stud overall structure, card is provided with particularly described stud
Circular row is gone back on system circle and limiting section, and the outer surface of limiting section body and is provided with multiple arcs cutting face, can be played well
Spacing, the anti-effect of spinning, realization is fastenedly connected；2. by by the spiral shell on first screw rod dorsad a shaft end of the back-up ring
The screw thread of line and second screw rod dorsad on a shaft end of the polished rod is both designed as round thread, can play very well
Correcting effect, beneficial to the installation of stud.
Brief description of the drawings
Fig. 1 is the cross-sectional view at the visual angle of stud one described in the utility model；
Fig. 2 is the cross-sectional view at another visual angle of stud described in the utility model.
With reference to accompanying drawing, make the following instructions：

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 stud respectively described in the utility model
Structure schematic diagram.
The stud includes coaxial line and the first integral screw rod 1, back-up ring 2, blocking circle 3, limit is linked in sequence
Position portion 4, the screw rod 6 of polished rod 5 and second, wherein, the back-up ring 2 and blocking circle 3 are disc structure, and the limiting section 4 has
Circular row is gone back on the body of one cylindrical shape, and the outer surface of the body and is provided with multiple arcs cutting face.
In the present embodiment, it is preferred that the external diameter of the back-up ring 2 is more than the external diameter of the blocking circle 3, and the back-up ring 2
Axial width and the blocking circle 3 axial width it is unequal, you can according to actual demand, by the axial width of the back-up ring
It is designed to be more than or less than the axial width with the blocking circle.
It is preferred that, each arc milling face is along the axially extending of the body.
It is further preferred that the arc milling face is six, and six arc milling faces are around the body
Axis is symmetric.
In the present embodiment, the screw thread and described second of first screw rod 1 dorsad on a shaft end of the back-up ring 2
Screw thread of the screw rod 6 dorsad on a shaft end of the polished rod 5 is round thread, and round thread plays correcting, beneficial to double end spiral shell
The installation of bolt.
In the present embodiment, also in first screw rod 1, back-up ring 2, blocking circle 3, limiting section 4, the screw rod 6 of polished rod 5 and second
Outer surface on be all coated with one layer of zinc layers respectively, improve the rust-resisting property of bolt product.
In summary, compared to prior art, spy is more suitable in the overall structure of stud described in the utility model
It is provided with different situation, particularly described stud on blocking circle and limiting section, and the outer surface of limiting section body and goes back circular row
Multiple arcs cutting face is provided with, spacing, the anti-effect of spinning well can be played, realization is fastenedly connected.
