[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To ensure the reliability of square and rectangular tubes, such as Figure 1-6 As shown, the rectangular tube with a tube head protection mechanism of the present invention includes a rectangular tube 1 and a tube head protection part, wherein the tube head protection part is respectively disposed at both ends of the rectangular tube 1.

[0024] The pipe head protection part includes a rubber pad 2, and a metal plug-in inner sleeve 21 is provided on one side of the rubber pad 2. The two ends of the square and rectangular tube 1 are respectively provided with plug interfaces 11 corresponding to the metal plug-in inner sleeve 21, and an inner end plate 12 is welded to the plug interface 11.

[0025] When in use, the rectangular tube 1 and the tube head protection part provide the users with a rectangular tube structure that is resistant to impact and has good shock absorption. This ensures that when the rectangular tube is installed and in use, the tube head will not cause significant harm to people in the vicinity. When used indoors, it can also avoid serious damage to walls and other surfaces, making the use of rectangular tubes safer and more reliable.

[0026] The insertion interface 11 has symmetrically provided sliding grooves 18 on both sides, and a slider 13 is provided in the sliding groove 18. A hook 14 is connected to the side of the slider 13 near the inner wall of the insertion interface 11, and a buckle groove 15 is provided on the side of the slider 13 away from the hook 14.

[0027] When in use, pull down the slot 15 on the slider 13 with your finger to move the slider 13 down until the hook 14 on the slider 13 is aligned with the position of the slot 22 on the tube head protection part to be inserted. Then insert the metal insertion inner sleeve 21.
