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.

The outer tube is formed by weaving elastic wires or the combination of the elastic wires and inelastic wires, so that the telescopic action of the outer tube and the inner tube can have a relatively synchronous force, the friction force between the outer tube cloth sleeve and the elastic inner tube is reduced, that is to say, the elastic wires have better elasticity, when the inner tube is stretched by water pressure, the elastic wires can stretch along with the inner tube, the problem of service life reduction caused by friction between the outer tube cloth sleeve and the inner tube in the traditional outer tube cloth sleeve of the water tube is avoided, the outer tube has good elasticity, can stretch synchronously with the outer tube in use, and the friction between the inner tube and the outer tube is reduced, so that the service life of the inner tube is effectively prolonged.
After the outer tube is woven by elastic wires or the combination of the elastic wires and inelastic wires, the appearance flexibility is stronger, compared with a traditional cloth sleeve outer tube, in the same size, the telescopic length of the outer tube can be longer, the elastic wires have longer stretching length, the inelastic wires can be stretched along the elastic wires, the maximum stretching ratio of the outer tube can reach 10 times of the shrinking length, and the stretching ratio of the telescopic water tube is greatly increased.
