Several adapter grooves 303 are opened on the side wall of the first flange 301 near the second flange 302. Several limiting blocks 306 are correspondingly arranged with the adapter grooves 303. Locking bolts 307 are provided through the side walls of the first flange 301 and the second flange 302. Nuts 304 are slidably sleeved on the locking bolts 307.

[0023] Specifically, by setting the first flange 301 and the second flange 302 symmetrically, the adapter groove 303 opened inside the first flange 301 can be symmetrically adapted to the limiting block 306 set inside the second flange 302 on the other side, so that the connection of the pipe body can be fast and accurate. At the same time, the locking bolt 307 and nut 304 can further improve the sealing between the two flanges.

[0024] Among them: a number of limiting blocks 306 are distributed at equal intervals, and the number of limiting blocks 306 are coaxially arranged with the second flange 302;

[0025] Specifically, the limit blocks 306 are set with equal spacing in a ring, which ensures the stress stability between the two flanges and greatly improves the sealing performance.

[0026] Wherein: the fastening mechanism 2 includes a left fixed tube 202, a right fixed tube 206, a left sealing shell 201 and a right sealing shell 205.

The left fixed tube 202 and the right fixed tube 206 are both sleeved on both sides of the outer wall of the tube body 1.

[0027] Specifically, the interiors of the left fixed tube 202 and the right fixed tube 206 are respectively set to correspond to the left sealing shell 201 and the right sealing shell 205, so as to achieve the sealing and fixing effect with the first flange 301 and the second flange 302 set on the inner wall.

Two adjusting bolts 204 are provided and are symmetrically installed at both ends of the fixed block 203. There are two sets of fixed blocks 203, which are symmetrically distributed on both sides of the left fixed tube 202 and the right fixed tube 206.

[0029] Specifically, the fixed block 203 and adjusting bolt 204 can increase the stability of the fixed pipe and facilitate installation and disassembly.

[0030] Among them, the first flange 301 and the second flange 302 have mounting holes 305 on both side walls, and the locking bolts 307 are slidably disposed in the mounting holes 305.

[0031] Among them: sealing gaskets are provided at the connection between the left fixing tube 202 and the right fixing tube 206, and the left fixing tube 202 and the right fixing tube 206 are mirror images;

[0032] Specifically, by setting the left fixed tube 202 and the right fixed tube 206 as a mirror structure, the sealing and stability of both sides can be further enhanced when connecting and installing the tube body 1.

[0033] The working principle of the above embodiment is as follows: In use, by setting the first flange 301 and the second flange 302 opposite to each other, the internal limiting block 306 can be inserted and limited with the adapter groove 303 on the other side to complete the splicing and fixing. At the same time, the locking bolts 307 and nuts 304 set externally achieve the fastening effect of the first flange 301 and the second flange 302. The left sealing shell 201 and the right sealing shell 205 set mirrored on the outer wall of the first flange 301 and the second flange 302 achieve further sealing and fixing. At the same time, the left fixing pipe 202 and the right fixing pipe 206 set on both sides achieve the fastening effect, thereby improving the connection requirements of the pipe body 1 to have efficient sealing, stability and safety when connected, thus meeting the needs.
