Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0029] The technical solution of the present invention is to provide a pipe with the following structure, including a pipe body that is stretchable along the length direction, and a plurality of flexible convex rings extending outward from the wall of the pipe body when the pipe body is naturally contracted. In the state of natural contraction of the main body of the pipe, the pipe wall is integrally extended inward with several flexible concave rings. The flexible convex rings and flexible concave rings are arranged at intervals along the length direction of the main body of the pipe and connected by connecting sections. The outer part of the flexible convex ring The diameter is 1.5-2.5 times of the inner diameter of the flexible concave ring.
[0030]After adopting the above structure, compared with the prior art, the pipe of the present inve...
