However, the ordinary telescopic water pipe is not durable and has a short service life. The cloth casing will lose the compressive effect of the cloth casing, causing the inner pipe to expand and burst from the rupture of the cloth casing; the second is that the outermost cloth casing is easily broken due to wear during use, and the sharp sand on the ground Stone particles and plant thorns will pierce the cloth sleeve, and then directly pierce the inner tube, causing the inner tube to break; the third is that the cloth sleeve is pulled on the ground, and it is easy to stick to muddy water and dust, which is not conducive to cleaning and storage

Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-Figure 4 :
[0027] A wear-resistant multi-layer telescopic water pipe, comprising a retractable inner pipe 30 and a cloth sleeve 20 set outside the inner pipe 30, the outside of the cloth sleeve 20 is sleeved with a retractable wear-resistant protective layer 10, the The cloth sleeve 20 is a one-layer or two-layer or three-layer or four-layer or more flexible corrugated or straight-shaped cloth sleeve 20, and all layers of the cloth sleeve 20 are woven into an integrated structure or Independent single-layer structures are formed by nesting each other.
[0028] When the cloth sleeve pipe 20 stretches, the outer bottom surface 22 of the trough of the cloth sleeve pipe 20 can slide axially on the outer surface of the inner pipe 30 .
[0029] The above-mentioned wear-resistant protective layer 10 can expand and contract with the expansi...

The invention belongs to the technical field of telescopic water pipes, relates to a wear-resistant multi-layer telescopic water pipe. The telescopic water pipe includes a telescopic inner pipe and a cloth cover pipe with which the outside of the inner pipe is sleeved, the cloth cover pipe is a one-layer or multiple-layer telescopic and corrugated or straight-barrel-shaped cloth cover pipe, and the outer side of the cloth cover pipe is sleeved with a telescopic wear resistant protective layer. The telescopic water pipe has the advantages that 1, the pressure bearing capacity of the telescopic water pipe is improved; 2, the cloth cover pipe is effectively prevented from being worn and scratched, entering of sand particles and thorns of plants is prevented, and the service life of the whole telescopic water pipe is prolonged; 3, even if the telescopic inner pipe is broken, the wear resistant protective layer of the outermost layer has a certain compressive capacity, it is ensured that the water pipe can still continue to use, and the service life of the water pipe is prolonged; 4, the surface of the wear resistant protective layer of the outermost layer is smooth and easy to clean.
Description
technical field [0001] The invention belongs to the technical field of telescopic water pipes, in particular to a wear-resistant multilayer telescopic water pipe. Background technique [0002] Generally, water pipes are needed for car washing or watering in gardens. At present, telescopic water pipes are very popular. However, the ordinary telescopic water pipe is not durable and has a short service life. The cloth casing will lose the compressive effect of the cloth casing, causing the inner pipe to expand and burst from the rupture of the cloth casing; the second is that the outermost cloth casing is easily broken due to wear during use, and the sharp sand on the ground Stone particles and plant thorns will pierce the cloth sleeve, and then directly pierce the inner tube, causing the inner tube to break; the third is that the cloth sleeve is pulled on the ground, and it is easy to stick to muddy water and dust, which is not conducive to cleaning and storage.
