[0023] As Figures 1 to 2As shown, the connecting part includes: a first flange 5 installed on one side of the first pipe 2; a second flange 6 installed on one side of the second pipe 3 and configured to flange-connect the first pipe 2 and the second pipe 3 by mating the first flange 5 with the second flange 6.

[0024] As Figure 2 shown, it further includes: two sets of sealing grooves 7 respectively formed on the first pipe 2 and the second pipe 3 and configured such that when one side of the first pipe 2 and the second pipe 3 is fixed by the connecting part, the two sets of sealing grooves 7 communicate with each other to fix the sealing ring 4 in the two sets of sealing grooves 7.

[0025] As Figures 2 to 3 shown, the pushing part includes: multiple sets of pushing grooves 8 evenly formed on the first pipe 2 and the second pipe 3, and the pushing grooves 8 communicate with the sealing grooves 7; multiple sets of pushing plates 9, with one set of pushing plates 9 installed in each set of pushing grooves 8, and the side of the pushing plate 9 close to the central axis of the pipe abuts against the sealing ring 4; multiple sets of through grooves 10 evenly formed on the connecting part and the pipe body 1; multiple sets of pushing rods, with one set of pushing rods installed in each set of through grooves 10, and one side of the pushing rod is connected to the pushing plate 9 so that after pushing the pushing rod, the pushing plate 9 moves towards the sealing ring 4.

[0026] As Figure 3 shown, the pushing rod includes: a first pushing rod 11 installed on the first pipe 2; a second pushing rod 12 installed on the second pipe 3; after the first pipe 2 and the second pipe 3 approach each other, the first pushing rod 11 and the second pushing rod 12 engage with each other.

[0027] Embodiment 2: As Figure 4 shown, the limiting part includes: a first limiting frame 13 installed on the first flange 5, and one side of the first limiting frame 13 is connected to the first pushing rod 11; a second limiting frame 14 installed on the second flange 6, and one side of the second limiting frame 14 is connected to the second pushing rod 12.

Specifically, the first push rod 11 installed on the first pipe 2 and the second push rod 12 installed on the second pipe 3 are engaged with each other, and when pushed, they act together. The movement of the push plate 9 will squeeze the sealing ring 4, causing the sealing ring 4 to contract and be closer to the inner wall of the pipe body 1, thereby enhancing the sealing performance. In addition, in order to maintain the stable state after pushing, the first limiting frame 13 is installed on the first flange 5 and connected to the first push rod 11, and the second limiting frame 14 is installed on the second flange 6 and connected to the second push rod 12.
