[0026] Please combine Figures 1 to 4 As shown, this utility model provides a corrugated pipe that is easy to splice. The end of the corrugated pipe body 1 is provided with an internal thread area and an external thread area. An inner combined pipe 3 is threadedly connected to the internal thread area, and an outer combined pipe 2 is threadedly connected to the external thread area. A connecting ring 9 is fixedly installed at both ends of the outer combined pipe 2 in the length direction.

[0027] Among them, a fixing ring 5 is fixedly installed on the end of the corrugated pipe body 1. Multiple second bolts 13 are equally spaced on the circumference of the fixing ring 5. The multiple second bolts 13 are equally spaced on the circumference of the fixing ring 5. One end of the second bolt 13 passes through the interior of the fixing ring 5 and the connecting ring 9. A second nut 14 is threaded onto the second bolt 13.

[0028] During the assembly process, after the outer composite pipe 2, the movable ring 6, and the sealing gasket 7 are fitted onto the end of the bellows body 1, the inner composite pipe 3 is then threaded between the two bellows bodies 1. After the inner composite pipe 3 is installed, the outer composite pipe 2 is rotated and adjusted to the appropriate position. At this point, the outer composite pipe 2 and the inner composite pipe 3 have connected the two bellows bodies 1. With the help of the outer composite pipe 2 and the inner composite pipe 3, it is no longer necessary to change the length of the bellows body 1 to adapt to different installation environments, thus increasing its applicability. After the splicing is completed, multiple second bolts 13 and second nuts 14 are used to fix the fixing ring 5 and the connecting ring 9 to increase the firmness of the outer combined pipe 2 connecting the two corrugated pipe bodies 1. In addition, a limiting ring 8 is fixedly installed on the inner surface of the corrugated pipe body 1. The distance between the limiting ring 8 and the port of the corrugated pipe body 1 is less than the length of the inner combined pipe 3. Furthermore, after the inner combined pipe 3 is installed inside the two corrugated pipe bodies 1, the inner combined pipe 3 will not completely enter the interior of one of the corrugated pipe bodies 1, thus maintaining the connection between the two corrugated pipe bodies 1.

[0029] A movable ring 6 and a sealing gasket 7 are provided between the connecting ring 9 and the fixed ring 5. Both the movable ring 6 and the sealing gasket 7 are sleeved on the outside of the bellows body 1. The sealing gasket 7 is located between the movable ring 6 and the connecting ring 9. A clamping assembly is installed on the fixed ring 5. The clamping assembly includes a first bolt 10, a first nut 11, and a washer 12. The first nut 11 and the washer 12 are both sleeved on the outside of the first bolt 10. One end of the first bolt 10 passes through the inside of the fixed ring 5 and is threadedly connected to the fixed ring 5. The movable ring 6 is clamped by one end of multiple first bolts 10. After the movable ring 6 is under pressure, it presses the sealing gasket 7 onto the connecting ring 9. The sealing gasket 7 can further improve the sealing performance after the two bellows bodies 1 are connected.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way.
