Telescopic water pipe

Abstract

The invention discloses a telescopic water pipe. The telescopic water pipe comprises an elastic inner pipe for allowing liquid to pass through and a weaving layer, wherein the elastic inner pipe has a shrinkage length and an extending length under the action of the pressure of the liquid passing through the elastic inner pipe; the weaving layer is wrapped around the outer circumferential surface of the elastic inner pipe; and the elastic inner pipe and the weaving layer form a first telescopic pipe body jointly, the first telescopic pipe body stretches and retracts along with stretching and retracting of the elastic inner pipe, and the outer diameter of the elastic inner pipe under the retracting length and the stretching length is close to the outer diameter of the elastic inner pipe under the corresponding length. Thus, the weaving layer protects the elastic inner pipe from being damaged by external sandstones and miscanthus, the weaving layer can be synchronously stretches and retracts along with the elastic inner pipe, the elastic inner pipe cannot be ground, and the service life of the first telescopic pipe body is prolonged; and due to the fact that the weaving layer is woven on the elastic inner pipe in a gapless mode, the use amount of the weaving layer is saved, the prepared first telescopic pipe body is small in size, small in the occupied space and light in the weight, and the first telescopic pipe body with unlimited length can be prepared.

Description

technical field [0001] The invention relates to a water pipe, in particular to a telescopic water pipe. Background technique [0002] Because the area of ​​the garden is generally larger, in order to reduce the work intensity of gardening workers to water the garden, generally adopt telescopic water pipes (for example, adopt elastic latex water pipes) to water the garden; meanwhile, in order to avoid the latex water pipes from being If the ground is pierced by sharp gravel particles or plant thorns, an outer tube will generally be set on the outside of the latex water pipe. For example, the utility model patent with the patent notification number CN203052052U discloses a retractable water pipe. A sheath is provided outside the elastic inner tube to protect the elastic inner tube from being punctured. [0003] However, although the problem of the elastic inner tube being punctured by external force has been solved by adding a sheath, when the sheath is added, due to the expa...

AI Technical Summary

Problems solved by technology

From understanding the production process of other industries, the inventor noticed that the production process of the outer layers of various cloth sleeves has already been automated and equipment-based. At present, the telescopic water pipe industry uses the outer layers of cloth sleeves to buy finished products and then manually pack them, which not only brings The elastic inner tube is worn by the sheath, and its production efficiency is heavily dependent on labor, and the room for efficiency improvement is limited
