[0032] Specifically, the end connection structure includes a connecting ring 8 fixed to the end of the pipe. Several connecting rings 8 are arranged at intervals in the circumferential direction of the pipe end, and a clearance hole 9 is formed between adjacent connecting rings 8. A limiting groove 10 is provided on the side of the connecting ring 8 facing away from the end face of the pipe. The setting of the connecting ring 8 can prevent the extrusion ring from moving relative to the connecting ring 8 in the circumferential direction of the air duct after the limiting block 11 on the extrusion ring is inserted into the limiting groove 10.

[0033] like Figure 5 As shown, the end ring structure in this embodiment is respectively mounted on the ends of the first pipe 1 and the second pipe 2, and the end ring structure is snap-fitted with the end connection structure so that the end ring structure first realizes circumferential limitation of the first pipe 1 and the second pipe 2, and a second sealing structure is arranged between the end ring structures.

[0034] Specifically, the end ring structure includes an annular extrusion ring. In this embodiment, the extrusion ring includes a first extrusion ring 6 and a second extrusion ring 18. The inner side surface of the first extrusion ring 6 is circumferentially spaced with limit blocks 11. The limit blocks 11 are arranged on the side of the first extrusion ring 6 away from the end face of the pipe. The limit blocks 11 are snap-fitted with the limit grooves 10. The clearance hole 9 provides a clearance space for the limit blocks 11 to move axially along the pipe when the end ring structure is sleeved on the end of the pipe. In this embodiment, the first extrusion ring 6 is first sleeved on the end of the first pipe so that the first extrusion ring 6 moves axially along the first pipe. At this time, the limit block 11 on the first extrusion ring 6 passes through the clearance hole 9 on the first pipe 1 along the axial direction of the first pipe, and then the first extrusion ring 6 is rotated so that the limit block 11 on the first extrusion ring 6 is aligned with the limit groove on the first pipe connecting ring, and then the first extrusion ring 6 is pushed toward the end of the first pipe so that the limit block on the first extrusion ring 6 is inserted into the limit groove 10 on the connecting ring 8 on the first pipe 1.

[0039] The arc-shaped plate 13 is an arc-shaped structure with a “person” shape in cross section, and the arc-shaped plate 13 clamps and fixes the two extrusion rings.

[0040] As shown in Figure 1 , the mounting hanger 3 is a “U”-shaped frame with an opening facing one side, and the mounting hanger 3 is provided with a positioning plate 5 matched with the outer circumferential surface of the pipeline.

[0041] In this embodiment, the positioning plate 5 and the mounting hanger 3 cooperatively form a mounting cavity 4, so that the pipeline can be placed in the mounting cavity 4.

[0042] As shown in Figure 4 , the upper and lower sides of the mounting hanger 3 are respectively provided with accommodating grooves 12 accommodating the clamping structures, and when the screw rod 14 is rotated, the arc-shaped plate 13 can move up and down along the accommodating grooves 12 to limit the accommodating grooves 12.
