Pipe, pipe manufacturing method and stretchable water pipe

Abstract

The invention discloses a pipe, a pipe manufacturing method and a stretchable water pipe. The pipe is stretchable and uniform in structure and will not generate wrinkling angles when stretching or retracting. According to the technical scheme, the pipe is characterized by comprising a pipe body capable of stretching and retracting in the length direction, the pipe wall extends outwards integrally to form a plurality of flexible convex rings when the pipe body is in the natural retracting state, the pipe wall extends inwards integrally to form a plurality of flexible concave rings when the pipe body is in the natural retracting state, and the pipe body of the structure can deform uniformly; during retracting, the outer wall of the pipe is composed of outer walls of the multiple flexible convex rings, the inner wall of the pipe is composed of inner walls of the multiple flexible concave rings, and the shapes are uniform; due to the fact that no irregular wrinkles exist and no sharp wrinkle angles exist, materials inside and outside the pipe or skin will not be scratched; and during stretching, the pipe is in a similar pipe shape, in other words, the inner wall and the outer wall are of the micro wavy structures, the inner and outer wall stress of the pipe can be effectively buffered, the pipe has the good structural strength and can achieve uniform shape deformation, and the good application market is achieved.

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 ZL201320634454.5 (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 a high-strengt...

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
