[0020] Please refer to Figure 1 A water pipe comprises a pipe body, wherein the pipe body comprises an inner pipe 1, a middle pipe 2 and an outer sleeve 3 which are sequentially sleeved from the inside to the outside, wherein the inner pipe 1 is a plastic corrugated pipe, the middle pipe 2 is a rubber sleeve, and the outer sleeve 3 is made of fiber material.

[0021] From the above description, it can be seen that the beneficial effects of the utility model are: the inner tube 1 of the water pipe is a plastic corrugated tube with good expansion and contraction performance, high toughness, high impact resistance and high flexibility, which can withstand the long-term impact of water flow and is not easy to burst; the middle tube 2 made of rubber material can greatly improve the pressure resistance of the water pipe and extend the service life of the water pipe; the outer sleeve 3 made of fiber material can protect the middle tube 2 from being directly worn or scratched and punctured during the pulling process, further extending the service life of the water pipe.

[0022] Furthermore, the cross section of the inner tube 1 is circular.

[0023] From the above description, it can be seen that the circular pipe has high impact resistance and is not easy to be damaged.

[0024] Furthermore, the cross section of the middle tube 2 is circular.
