[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0025] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present application provides an embodiment: a high-drawing force nut mounting structure, comprising a pipe body 1, a mounting sleeve 2 and a tower joint body 3, the mounting sleeve 2 is sleeved on one end of the pipe body 1, used for connecting with the tower joint body 3, the tower joint body 3 is inserted into one end of the pipe body 1 provided with the mounting sleeve 2, used for connecting the pipe body 1 with other equipment.

[0026] The tower joint body 3 comprises a boss 31 and a connecting pipe 32 in communication with the boss 31, the outer periphery of the boss 31 is designed in a hexagonal structure, and the inner wall of the boss 31 is provided with an inner ring groove 311, which is used for realizing the plug-in installation of other equipment and the boss 31.

[0027] Specifically, the outer periphery of the boss 31 is designed in a hexagonal structure and the inner wall is provided with an inner ring groove 311, which realizes the plug-in installation of other equipment and the boss 31, and the hexagonal structure is beneficial to tool operation, improving the installation convenience and stability.

[0028] The connecting pipe 32 is cylindrically arranged, and is made of copper material, and has a certain outward expansion ductility. The inner diameter of the pipe body 1 is matched with the outer diameter of the connecting pipe 32, and one end of the connecting pipe 32 away from the boss 31 is inserted into the pipe body 1.

[0029] Specifically, before the connecting pipe 32 is inserted into one end of the pipe body 1 provided with the mounting sleeve 2, the outer wall of the connecting pipe 32 is coated with glue.

[0030] The mounting sleeve 2 is made of metal material, and is arranged in a circular ring shape, and has a corrugated section on the mounting sleeve 2, and the mounting sleeve 2 is sleeved on one end of the pipe body 1.

[0031] Thus, after the mounting sleeve 2 is sleeved on one end of the pipe body 1 and the connecting pipe 32 is inserted into the same end of the pipe body 1, the expanding tool is inserted into the position of the connecting pipe 32 of the bell joint body, the expanding tool expands the connecting pipe 32 radially from inside to outside, at this time, the connecting pipe 32 abuts against the mounting sleeve 2, due to the limiting effect of the mounting sleeve 2, the connecting pipe 32 forms a corrugated shape matched with the corrugated section of the mounting sleeve 2, and the pipe body 1 forms a corrugated groove 11 correspondingly.

[0032] The application assembles the connecting pipe 32, the pipe body 1 and the mounting sleeve 2 together by the above-mentioned mode, thereby enhancing the stability of the overall structure and reducing the risk of loosening.
