Technical Field

The invention relates to the field of non-standard hardware parts, in particular to an arc screw.

Background

At present, a general screw is linear, a nut can only do linear motion along the screw, an installation mode of an elevation angle adjustment type bolt cannot be directly fixed by the installation mode of the general screw, especially when wireless communication equipment is installed, the installation of the elevation angle adjustment type bolt is more common, if the general screw is bent and processed into an arc screw, the screw pitches of the inner side and the outer side of the arc can be changed, and the nut can interfere with the screw to be incapable of working.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the arc screw, and solves the problems of strong interference and incapability of normally fixing the arc screw in the working process.

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides an arc screw, includes at least one spiral monomer, spiral monomer includes first region, second region, third region and fourth region, the first region is flat district, the second region is spiral district and distributes in first region both sides with the third region, the second region is greater than the second radius in fourth region with the first radius at third region for spiral monomer's cross-section center, spiral monomer arranges in proper order in order to form the arc screw.

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

Preferably, the fourth region is disposed on a concave side of the spiral cell.

Preferably, the first region is disposed on the convex side of the spiral single body.

Preferably, the fourth area occupies 1/4-1/2 relative to the section arc of the spiral monomer.

The invention has the following beneficial effects:

the plurality of spiral single bodies are sequentially arranged to form the arc-shaped screw rod, the installation mode of elevation angle adjustment can be met, the interference problem in the installation process of the screw rod is reduced, the corresponding nuts can do curvilinear motion along the arc-shaped screw rod, and the spiral screw rod installation device has the advantages of being wide in application range and good in effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the circular arc screw comprises at least one spiral monomer, wherein the spiral monomer comprises a first area 1, a second area 2, a third area 3 and a fourth area 4, the first area 1 is a flat area, the second area 2 and the third area 3 are spiral areas and are distributed on two sides of the first area 1, the first radius of the second area 2 and the first radius of the third area 3 relative to the center of the cross section of the spiral monomer are larger than the second radius of the fourth area 4, and the spiral monomer is sequentially arranged to form the circular arc screw.

The spiral single bodies are divided into the flat area and the spiral area, and the spiral single bodies are sequentially arranged to form the arc-shaped screw rod, so that the spiral single bodies are conveniently matched and fastened with the nuts, and the corresponding nuts can do curvilinear motion along the arc-shaped screw rod.

In a preferred embodiment, the second region 2 and the third region 3 are symmetrically arranged relative to the first region 1, the fourth region 4 is arranged on the concave side of the spiral single body, the first region 1 is arranged on the convex side of the spiral single body, and the fourth region 4 occupies 1/4-1/2 relative to the section arc of the spiral single body.

Through setting up second region 2 and third region 3 for first region 1 symmetry, nut 6 is at rotatory screw-up's in-process, and direct and the screw-thread fit that second region 2 third region 3 set up fastens, and the fixed stability of multiplicable nut 6 of symmetry setting reduces the probability of thread slipping, and fourth region 4 accounts for 1/4 ~ 1/2 for spiral monomer cross-section circular arc, reduces the interference nature of nut in rotatory fixed.

The invention has the following beneficial effects:

the plurality of spiral single bodies are sequentially arranged to form the arc-shaped screw rod, the installation mode of elevation angle adjustment can be met, the interference problem in the installation process of the screw rod is reduced, the corresponding nuts can do curvilinear motion along the arc-shaped screw rod, and the spiral screw rod installation device has the advantages of being wide in application range and good in effect.
