Description

TECHNICAL FIELD

[0001] The present application relates to the field of non-standard hardware components, in particular to an arc screw. BACKGROUND

[0002] At present, the general screw is linear, and the nut can only move linearly along the screw. For the installation mode of the elevation angle adjustment type, the ordinary bolt installation mode cannot directly fix it, especially when installing wireless communication equipment, the installation of the elevation angle adjustment type is more common. If the ordinary screw is bent and processed into an arc screw, the pitch of the inner side and the outer side of the arc will change, and the nut will interfere with the screw and cannot work. SUMMARY

[0003] In view of the defects of the prior art, the present application provides an arc screw, which solves the problems of strong interference and inability to fix normally during the working process of the arc screw.

[0004] To achieve the above purpose, the following technical scheme is adopted: an arc screw, comprising at least one spiral monomer, the spiral monomer comprising a first region, a second region, a third region and a fourth region, the first region being a flat area, the second region and the third region being spiral areas and being distributed on both sides of the first region, the first radius of the second region and the third region relative to the cross-sectional center of the spiral monomer being greater than the second radius of the fourth region, and the spiral monomers being arranged in sequence to form an arc screw.

[0005] Preferably, the second region and the third region are symmetrically arranged relative to the first region.

[0006] Preferably, the fourth region is arranged on the concave side of the spiral monomer.

[0007] Preferably, the first region is arranged on the convex side of the spiral monomer.

[0008] Preferably, the fourth region accounts for 1 / 4 to 1 / 2 of the cross-sectional arc of the spiral monomer.

[0009] The present application has the following advantages:

[0010] By arranging a plurality of spiral monomers in sequence to form an arc-shaped screw, the installation mode of the elevation angle adjustment type can be met, the interference problem in the screw installation process can be reduced, and the corresponding nut can move in a curve along the arc screw, thereby having the characteristics of wider use range and better effect.

[0017] By dividing the helical monomer into a flat area and a helical area and arranging the helical monomers in sequence to form the arc screw rod, the nut can be conveniently fastened, and the corresponding nut can be made to move in a curve along the arc screw rod.

[0019] By symmetrically arranging the second area 2 and the third area 3 relative to the first area 1, the nut 6 is directly fastened with the threads arranged on the second area 2 and the third area 3 during rotation and tightening, and the symmetric arrangement can increase the stability of the nut 6 and reduce the probability of slipping off. The fourth area 4 accounts for 1 / 4-1 / 2 of the cross-sectional arc of the helical monomer, reducing the interference of the nut during rotation and tightening.
