Problems solved by technology

[0002] Bellows are often used in drainage facilities or equipment. When water flows through the bellows, the bellows will inevitably be deformed. Therefore, the anti-deformation force of the bellows will greatly affect its service life. At present, the expansion and contraction capacity of most bellows Poor, so less durable

Abstract

The invention discloses a durable type corrugated pipe. The corrugated pipe comprises a plurality of annular protruding portions and annular concave portions, and the annular protruding portions and the annular concave portions are alternatively arranged. The cross sections of the protruding portions are triangular, and the cross sections of the concave portions are in an inverted trapezoid shape, so that the anti-deformation action force of the corrugated pipe can be effectively improved. Therefore, the environmental adaptability and the durability of the corrugated pipe are improved. The structure improvement of the durable type corrugated pipe is simple, and the beneficial effect is obvious.

Description

technical field [0001] The invention relates to a hose, in particular to a bellows. Background technique [0002] Bellows are often used in drainage facilities or equipment. When water flows through the bellows, the bellows will inevitably be deformed. Therefore, the anti-deformation force of the bellows will greatly affect its service life. At present, the expansion and contraction capacity of most bellows Poor, so less durable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bellows with higher durability. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: [0005] A durable corrugated pipe includes a plurality of alternately arranged annular convex parts and annular concave parts, the cross section of the convex part is triangular, and the cross section of the concave part is inverted trapezoidal. [0006] Preferably, an annular reinfor...
