Abstract: Disclosed is a telescopic water pipe, comprising: an elastic inner pipe having a contraction length and an extension length under the pressure of the liquid passing therethrough; and a braided layer wrapped on an outer circumferential surface of the elastic inner pipe; wherein the elastic inner pipe and the braided layer form together a first telescopic pipe body, the first telescopic pipe body expanding and contracting with the expansion and contraction of the elastic inner pipe, its outer diameters being close to the outer diameters of the elastic inner pipe. Therefore, the braided layer can expand and contract synchronically with the elastic inner pipe without wearing out the elastic inner pipe, thereby prolonging the service life of the first telescopic pipe body. The amount of used braided layer is saved, and the obtained first telescopic pipe body has a small volume and an unrestricted length.

Abstract: Disclosed is a water pipe with synchronously retractable multi-layer, comprising: a retractable inner pipe; a fabric sleeve sleeved outside the inner pipe, which is configured as a retractable cylindrical or corrugated one- or multi-layer fabric sleeve formed by interweaving retractable elastic yarns arranged at intervals in the axial direction and non-retractable reinforcing yarns arranged at intervals in the circumferential direction; and a retractable plastic film layer interposed between the inner pipe and the fabric sleeve. According to the present disclosure, the inner pipe, the plastic film layer and the fabric sleeve can be synchronously retracted under the effect of water pressure change, so that the frictional damage among multiple layers is effectively reduced, and the service life of the entire retractable water pipe is prolonged.

Abstract: 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.
