[0025] The utility model embodiment discloses a corrugated pipe.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bellows includes a bellows body 100 , a first telescopic member 200 and a second telescopic member 300 .

[0027] The first telescopic member 200 has an A end and a B end. A first joint 210 is provided at the A end of the first telescopic member 200 .

[0028] The second telescopic member 300 is a tubular structure. The second telescopic member 300 has a C end and a D end. The D end of the second telescopic member 300 is provided with a second joint 310 .

[0029] In the installed state, the B end of the first telescopic member 200 is inserted into the second telescopic member 300 from the C end of the second telescopic member 300, so that the first telescopic member 200 is slidably connected with the second telescopic member 300. The bellows body 100 is sleeved outside the first telescopic member 200 and the second telescopic member 300. One end of the bellows body 100 is connected to the first joint 210, and one end of the bellows body 100 is connected to the second joint 310, so that the bellows body 100 can be stretched or compressed with the relative sliding between the first telescopic member 200 and the second telescopic member 300.

[0030] In addition, a first limiting structure 320 is provided on the inner wall of the second telescopic member 300 to limit the compression distance of the bellows body 100 .

[0031] The distance L between the first limiting structure 320 and the C end of the second telescopic member 300 is smaller than the maximum compression distance of the bellows body 100 .

[0032] The bellows of the utility model embodiment is provided with a first telescopic member and a second telescopic member that can slide and telescope and a first limiting structure in the bellows body. On the one hand, when the bellows body is compressed, the bottom end (end B) of the first telescopic member slides to the first limiting structure and is limited by the first limiting structure, thereby preventing the bellows body from being over-compressed and causing damage. On the other hand, due to the support of the first telescopic member and the second telescopic member, the bellows body is not easy to bend and become unstable when compressed, thereby greatly increasing the pressure it can withstand.

[0033] For example, in some embodiments, the first limiting structure 320 is a limiting platform formed on the inner wall of the second telescopic member 300, such as Figure 4 shown.

[0034] For example, in some embodiments, Figure 5 As shown, the first limiting structure 320 is a guide groove or a guide bar hole formed on the second telescopic member 300 .

[0035] In addition, a guide post 220 is provided on the first telescopic member 200. The guide post 220 is movably engaged in the guide groove or the guide bar hole.

[0036] The length of the guide groove or the guide strip hole is smaller than the maximum stretching distance of the corrugated tube body 100 .

[0037] The length of the guide groove or the guide strip hole is smaller than the maximum compression distance of the corrugated tube body 100 .

[0038] In some embodiments, the guide groove or the guide strip hole is obliquely arranged on the second telescopic member 300. The length of the guide groove or the guide strip hole is less than the length corresponding to the maximum twisting amount of the corrugated tube body 100.

[0039] By setting the first limiting structure 320 as a guide groove or a guide strip hole formed on the second telescopic member 300, and arranging a guide column 220 on the first telescopic member 200 to be slidably connected to the guide groove or the guide strip hole, the relative movement distance between the first telescopic member 200 and the second telescopic member 300 is limited by the length of the guide groove or the guide strip hole, thereby preventing the corrugated pipe body from being over-compressed, stretched or twisted, and causing damage to the corrugated pipe body. In addition, in this embodiment, due to the support of the first telescopic member and the second telescopic member, the corrugated pipe body can also be made not easy to bend and lose stability when compressed, so that the pressure it can withstand is greatly increased.

[0040] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0041] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
