[0020] like Figures 1-3 As shown, an optional embodiment of this utility model provides a lightweight anti-torsion shaped tube, including a square tube 1 and a recessed portion 2. The recessed portion 2 is provided on the outer side wall of the square tube 1, and the cross-section of the recessed portion 2 is rectangular. An anti-torsion mechanism 3 is welded to the inner wall of the square tube 1. The anti-torsion mechanism 3 includes a main rod 31, a secondary rod 32 and a support plate 33. The secondary rod 32 is welded to both ends of the main rod 31. The main rod 31 and the secondary rod 32 are connected in a T-shape. The front and rear ends of the secondary rod 32 are welded to the inner walls of the square tube 1 and the recessed portion 2, respectively. The support plate 33 is welded to the outer side wall of the main rod 31. The shape of the support plate 33 is consistent with the cross-section of the inner cavity of the square tube 1 and the recessed portion 2. The support plate 33 can fit into the inner cavity of the square tube 1 and the recessed portion 2.

[0021] In this embodiment, the recessed portion 2 at the irregular shape of the square tube 1 is used to meet unique structural or aesthetic requirements. At the same time, the recessed portion 2 can also enhance the structural stability of the irregular tube. Its two auxiliary rods 32 are flush with the end faces of both ends of the square tube 1, avoiding structural protrusions that may affect the subsequent installation of the irregular tube. In this device, both the square tube 1 and the anti-torsion mechanism 3 are made of aluminum, which makes the device lighter. Moreover, the anti-torsion mechanism 3 inside the square tube 1 can further improve the anti-torsion performance of the device. The square tube 1 and the recessed portion 2 are supported by multiple support plates 33 on the outside of the main rod 31, ensuring the structural stability of the device.

[0022] This utility model embodiment features a main rod 31, a secondary rod 32, and a support plate 33 within a square tube 1. In practical applications, the support plate 33 is welded to the outside of the main rod 31, with the spacing between each support plate 33 controlled at 200-250mm. Then, an anti-torsion mechanism 3 is inserted into the square tube 1. The position of the anti-torsion mechanism 3 is fixed by welding the secondary rod 32 to the square tube 1 and the recessed portion 2. At this time, the multiple support plates 33 on the outside of the main rod 31 support the square tube 1 and the recessed portion 2, ensuring the structural stability of the device and greatly improving its anti-torsion performance. Furthermore, since both the main rod 31 and the secondary rod 32 are hollow, the overall weight of the tube is significantly reduced, making the device lighter and easier to transport and install.

[0023] In one optional embodiment of this utility model, such as Figures 1-3 As shown, both the upper and lower ends of the square tube 1 are provided with splicing mechanisms 4. The splicing mechanism 4 includes positioning holes 41, positioning frames 42, and fixing bolts 43. The upper wall of the support plate 33 has positioning holes 41 with internal threads. Fixing bolts 43 are inserted into the upper walls of both ends of the positioning frame 42. The fixing bolts 43 can be screwed into the positioning holes 41. In this embodiment, the splicing mechanism 4 is used to realize the rapid assembly of multiple basic devices. The positioning holes 41 with internal threads on the support plate 33 can provide positioning during splicing. The positioning frame 42 can firmly connect two adjacent irregular tubes through the cooperation of the fixing bolts 43 at both ends and the positioning holes 41, which not only ensures the splicing accuracy but also avoids loosening at the splicing point.

[0024] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the side walls at both ends of the square tube 1 are provided with relief grooves 5, and the positioning frame 42 can be inserted into the relief grooves 5. In this embodiment, the relief grooves 5 at both ends of the square tube 1 provide relief for the positioning frame 42. After the positioning frame 42 is inserted into the relief grooves 5, it can prevent the positioning frame 42 from protruding from the end of the tube body, thereby enhancing the connection stability between the positioning frame 42 and the square tube 1.

[0025] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the side wall of the main rod 31 is provided with reinforcing ribs 6, and the upper wall of the reinforcing ribs 6 is welded to the lower wall of the support plate 33. In this embodiment, the reinforcing ribs 6 on the side wall of the main rod 31 can improve the stability of the connection between the support plate 33 and the main rod 31, prevent the support plate 33 from tilting or bending, and thus further enhance the torsional resistance of the shaped tube.

[0026] In one optional embodiment of this utility model, such as Figures 1-3 As shown, there are two positioning holes 41, which are respectively located on the left and right sides of the support plate 33.

[0027] In one optional embodiment of this utility model, such as Figures 1-3 As shown, both the main rod 31 and the secondary rod 32 are hollow tubes. The side wall of the secondary rod 32 has a through groove 7 that mates with the recessed portion 2. In this embodiment, the main rod 31 and the secondary rod 32 adopt a hollow tube design, which significantly reduces the amount of material used while ensuring the strength of the rod itself, further improving the portability of the device. The through groove 7 on the side wall of the secondary rod 32 that mates with the recessed portion 2 allows the secondary rod 32 to better fit the inner wall contour of the recessed portion 2, increasing the welding contact area and making the connection between the secondary rod 32 and the recessed portion 2 more secure.

[0028] In one optional embodiment of this utility model, such as Figures 1-3 As shown, a rubber pad 8 is fitted to the outer wall of the support plate 33, and the rubber pad 8 can fit into the inner cavity of the square tube 1 and the recessed part 2. In this embodiment, the rubber pad 8 on the outer wall of the support plate 33 can make the support plate 33 fit more tightly into the inner cavity of the square tube 1 and the recessed part 2 through the elastic deformation of the rubber, so as to avoid the two rubbing against each other and producing abnormal noise.

[0029] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the depth of the relief groove 5 is the same as the thickness of the positioning frame 42, and the positioning frame 42 is inserted into the relief groove 5 and flush with the end of the square tube 1. In this embodiment, after the positioning frame 42 is inserted into the relief groove 5, it can remain flush with the end of the square tube 1, ensuring the flatness of the tube end and avoiding protrusion that would affect the subsequent installation of the device.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
