[0002] Rectangular tubes are steel pipes with rectangular cross-sections, widely used in construction, machinery, automobiles, home appliances and other industries. Depending on the material, rectangular tubes can be made of carbon steel, stainless steel, aluminum alloy, etc. They have certain strength and rigidity and are suitable for structures that need to withstand large pressure or loads.

[0003] For example, a rectangular tube with easy positioning, disclosed in CN215406904U, includes a rectangular tube body, positioning slots, and positioning blocks. Inner rings are provided on the inner sides of both ends of the rectangular tube body, and reinforcing ribs are provided near the corners of the inner rings. Positioning slots are provided on both sides of one end of the rectangular tube body, and positioning blocks corresponding to the positioning slots are provided on both sides of the other end of the rectangular tube body. This novel rectangular tube has a pre-positioning structure before being welded into a longer tube body, facilitating welding work. The rectangular tube has a reliable threaded connection structure, which facilitates the connection and installation of external structures such as reinforcing bars, making it suitable for widespread use.

[0004] The aforementioned patent proposes that a pre-positioning structure can be achieved between rectangular tubes through the cooperation of positioning slots and positioning blocks, which is beneficial for subsequent welding. However, when the rectangular tubes are in use, they are prone to friction and wear due to contact between adjacent rectangular tube bodies, which affects the positioning accuracy between the rectangular tube bodies.

[0023] The gasket 3 includes a perforation 31 and an adhesive layer 32 uniformly coated on the sidewall of the gasket 3. The gasket 3 is adhered to the rectangular tube body 1 by means of the adhesive layer 32, so that the gasket 3 is located at one end of the rectangular tube body 1. When the two sets of rectangular tube bodies 1 approach and contact each other, the sealing of the connection part can be increased and wear can be reduced.

[0024] The positioning component 2 includes a first positioning block 21 and a second positioning block 22. The first positioning block 21 and the second positioning block 22 are both fixedly installed at one end of the rectangular tube body 1. The end of the rectangular tube body 1 away from the first positioning block 21 is provided with a positioning groove A23 and a positioning groove B24.
