摘要:
A wear-resistant multi-layer retractable water pipe, comprising a retractable inner pipe; a one- or multi-layer retractable fabric sleeve; and a retractable wear-resistant protective layer, wherein the retractable inner pipe is nested in the fabric sleeve, and the fabric sleeve is nested in the retractable wear-resistant protective layer. The present disclosure has the following advantages: the pressure bearing capacity of the water pipe is improved; second, the fabric sleeve is not easily worn and scratched, and the service life of the water pipe is prolonged; even if the inner pipe is broken, the outermost wear-resistant protective layer has a certain pressure resistance, ensuring that the water pipe can continue to be used, the service life of the water pipe is prolonged; and, the outermost wear-resistant protective layer has a smooth surface and therefore is easy to clean.
