Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-11, a telescopic water pipe with an elastic wire is arranged in the water pipe, and two ends of the water pipe 1 are respectively provided with a water pipe joint 2 for connecting a faucet and a water gun joint 3 for connecting a water gun or other assemblies.

The water pipe 1 shown includes outer tube 8 and inner tube 9, and the inner tube 9 shown is the elastic tube, and outer tube 8 shown is the cloth cover outer tube, and water pipe 1 is when using, because hydraulic pressure is strikeed, inner tube 9 is expanded and is pulled up under the hydraulic pressure effect, and through outer tube 8 protection when inner tube 9 expands, avoid inner tube 9 to expand too big bursting, the outer tube can also avoid inner tube and ground and other sharp object contact simultaneously, promotes life.

The outer tube comprises elastic wires 6 and inelastic wires, wherein the elastic wires 6 are latex wires or elastic wires, and the inelastic wires comprise warp wires 4 and weft wires 5.

The outer tube can be woven by elastic wires, when the outer tube is made of elastic wires, the outer tube is woven by at least 1 or more than 1 elastic wires, the elastic wires can be latex wires or elastic wires, 2 or more than 2 strands of elastic wires are woven into a round, flat or wavy cloth sleeve through a braiding machine, and the inner tube 9 is arranged in the outer tube.
