It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.

As a specific embodiment, as shown in fig. 1 to 6, the present embodiment provides a torsion driving tube used as a rotation main beam of a photovoltaic bracket, including: a pipe body 11 and at least one anti-torque groove 12. The pipe body 11 is a circular pipe. The anti-twisting groove 12 is formed along the length direction of the pipe body 11, is recessed on the outer surface of the pipe body 11, and is raised on the inner surface of the pipe body 11.

In this embodiment, the pipe body 11 is a circular pipe, which has a large bending and torsion resistance, and can transmit torque better than other pipe with other cross-sections. In addition, the anti-torsion groove 12 is formed in the pipe fitting main body 11, so that the anti-bending and anti-torsion capacity of the pipe fitting main body 11 can be further improved, the stability of the pipe fitting main body in the torsion process is improved, and the torque transmission efficiency is improved.

In another embodiment, as shown in fig. 1 to 6, on the basis of the above embodiments, the present embodiment provides a torsion transmission tube connection structure, which includes a connection tube 2, a bead 21, a first bolt 22, and a torsion transmission tube 1. The connecting pipe 2 is a round pipe, the inner diameter of the connecting pipe 2 is equal to or larger than the outer diameter of the pipe fitting main body 11, the connecting pipe 2 is provided with a through hole corresponding to the anti-torsion groove 12, and a first nut 23 is arranged at the position corresponding to the through hole. The cross-sectional shape of the pressing strip 21 corresponds to the cross-sectional shape of the anti-torque groove 12, the pressing strip 21 is fittingly arranged in the anti-torque groove 12, and the pressing strip 21 can be an aluminum strip. The first bolt 22 is screwed with the first nut 23, and penetrates into the connecting pipe 2 to be supported on the pressing bar 21.

When two torque transmission pipes are connected, the pressing strip 21 can be clamped in the anti-torque groove 12, the connecting pipe 2 is sleeved outside, the first bolt 22 penetrates into the connecting pipe 2, and the pressing strip 21 is abutted to complete connection. During the twisting process, the side wall of the batten 21 can be contacted with the side wall of the anti-twisting groove 12, so that the twisting force is dispersed to the contact position of the side wall, the transmission of the twisting force is carried out, and the stability of the connection position and the safety of the whole structure are improved.

So far, those skilled in the art can understand that the anti-torque groove 12 in the present solution is actually the key invention point of the present solution, and the present solution greatly improves the transmission effectiveness of the pipe fitting main body 11 by providing the anti-torque groove 12, and can be connected by matching with the pressing strip 21, the connecting pipe 2, and the first bolt 22 without adopting the traditional bolt through connection mode, thereby avoiding the situation of fracture caused by insufficient bolt strength on the project site. In the process of torsion transmission, the side wall of the torsion-resistant groove 12 can disperse the pressure of the pipe fitting main body 11, and the torsion is effectively conducted through the pressing strip 21, so that the effectiveness of torsion transmission and the safety of projects are improved. In addition, the round tube in this embodiment may be other cross-sectional shapes that increase bending and torsion resistance, as would be conventional to one of ordinary skill in the art.

In another embodiment, as shown in fig. 1, 3 and 5, on the basis of the above embodiment, the number of the anti-twist grooves 12 is two and is opened at the opposite side of the cross section of the pipe body 11 in the radial direction. In this embodiment, by providing two torsion-resistant grooves 12, the torsion can be dispersed to two places for transmission, thereby further dispersing the torsion, dispersing the pressure of the pipe main body 11, and improving the effectiveness of torsion transmission and the safety of the project. Wherein the torsion groove 12 is preferably an arc-shaped groove. The arc-shaped groove can transfer force to the groove wall when the pipe fitting main body 11 is twisted, so that torque is effectively transmitted, the internal stress of the groove wall can be optimized by the arc-shaped cross section structure, and the firmness of the anti-torsion groove 12 is enhanced. The arc-shaped groove is only the preferred scheme here, and other such as square groove, dovetail groove can realize this scheme promotion torque transmission efficiency, reduce, dispersion pipe fitting main part atress, and the recess shape that promotes the security should belong to technical field personnel's conventional replacement means.

In addition, a transition section 13 is arranged between the anti-torque groove 12 and the pipe fitting main body 11, the outer surface of the transition section 13 is in smooth transition, and the protruding direction of the anti-torque groove 12 is opposite to the cross section center of the pipe fitting main body 11. This embodiment can effectively get rid of the stress of junction through setting up changeover portion 13, increases pipe fitting main part 11's life and stability. Meanwhile, the arrangement mode of the anti-torsion groove 12 towards the central axis of the pipe fitting main body 11 enables the pipe fitting main body 11 to be of a symmetrical structure integrally, and the pipe fitting main body is easy to process and stable in structure.

In another embodiment, as shown in fig. 2, 4 and 6, on the basis of the above embodiment, the number of the anti-torsion grooves 12 may be four, and the grooves may be equally spaced along the circumference of the pipe fitting body 11. The more the number of the anti-torsion grooves 12 is, the larger the dispersion degree of the torsion force is, the smaller the force borne by the single anti-torsion groove 12 is, and the more the effect of the torsion force transmission is guaranteed. However, the number of the anti-twisting grooves 12 is not too large, and the too many anti-twisting grooves 12 increase the difficulty of processing and manufacturing the pipe fitting body 11 and increase the production cost. Four torsion-resistant recesses 12 are therefore preferably used here. Through setting up four antitorque recesses 12, can disperse torsion to transmitting everywhere to further dispersion torsion, also dispersed the pressure of pipe fitting main part 11, improved the security of the validity of torsion transmission and project. Four anti-torque groove 12 in this embodiment are seted up along the circumference of pipe fitting main part 11 equidistant, can be with torsion homodisperse to pipe fitting main part 11 circumference, avoid pipe fitting main part 11 to concentrate because the torsion damages, have increased project engineering's security and pipe fitting main part 11's life to a certain extent.
