[0002] At present, most of the existing telescopic water pipes on the market are composed of an inner core elastic tube and an outer protective sleeve. The elastic tube made of latex, rubber or TPR thermoplastic elastomer has high elasticity. When connected to 3-10 kg of pressurized water, its radial water passing area and longitudinal length can expand and extend by 2-4 times under the protection of the outer protective sleeve; when the pressurized water source is turned off, the telescopic water pipe quickly discharges the remaining water in the pipe under the action of the resilience of the inner core elastic tube and retracts to the original product size, which is convenient to use and is deeply loved by domestic and foreign customers.

[0003] However, after long-term use, the existing inner core elastic tube is prone to aging, which will not only cause the resilience ability to become worse, but also be prone to rupture, with a short service life. Moreover, the surface of the elastic tube made of latex or rubber material is relatively soft and is easily punctured by foreign objects, affecting the use. Content of the Utility Model
