Problems solved by technology

When in use, the inner elastic water pipe passes water, and the pipe expands under the pressure of the water and drives the outer braided pipe to stretch accordingly, and the final stretching state of the braided pipe determines the size of the water pipe. The defect of this kind of water pipe is that the outer braided pipe It plays the role of limiting the thickness and length of the water pipe, and because the outer braided pipe is naturally wrinkled, there will be sharp wrinkle angles, which will scratch the inner elastic water pipe when the inner elastic water pipe is elongated. When the telescopic water pipe is bent, and because the inner elastic water pipe becomes longer after being filled with water, the wall of the water pipe becomes thinner, which makes the inner elastic water pipe easier to damage. Even after a certain period of time, the inner elastic water pipe is easy to use. leak or even break

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...

Abstract

The invention discloses a pipe, a method for making the pipe and a telescopic water pipe, aiming to provide a pipe that can be stretched, has a uniform structure, and does not produce wrinkle angles when stretching. In the state of natural shrinkage of the pipe body, the pipe wall integrally extends outwards with several flexible convex rings, and in the state of natural shrinkage of the pipe body, the pipe wall integrally extends inward with several flexible concave rings. The pipe body of this structure can be uniform When deforming and shrinking, the outer wall of the pipe is composed of a number of flexible convex ring outer walls, and the inner wall is composed of a number of flexible concave ring inner walls. Or the skin, when stretched, the pipe is approximately tubular, that is, there are tiny wavy structures on the inner and outer walls, which can effectively buffer the force on the inner and outer walls of the pipe, so that the pipe has good structural strength and uniform shape deformation, and has a good application market.

Description

technical field [0001] The invention relates to a pipe material, more specifically to a pipe material, a pipe material manufacturing method and a telescopic water pipe. Background technique [0002] Generally, the length and thickness of water pipes are fixed. It is more troublesome to use when watering the garden, because when the place to be watered is far away from the water source, a longer water pipe needs to be used, and manual deployment is required before and after use. And put away the water pipe to facilitate storage, waste time, and bulky, easy to twist and knot, bring inconvenience to the staff, and also affect the work efficiency. [0003] For this reason, someone has invented a kind of telescopic water pipe, as a patent No. is ZL 201320634454.5 (announcement number is CN203517045U) Chinese utility model patent " telescopic water pipe " discloses such a kind of novel telescopic water pipe, it is characterized in that: comprise latex inner pipe and The high-stre...
