a stretch tube

Abstract

The invention provides an extensible pipe and belongs to the technical field of a flexible pipe. The extensible pipe solves the technical problem that an external pipe of the existing extensible pipe is inelastic and is required to be collected and stored in a wrinkle shape when not used for storing a water pipe and the like. The extensible pipe comprises an outer sleeve and an elastic internal pipe which is arranged inside the outer sleeve; the outer sleeve comprises inelastic wefts, inelastic fixing wires and elastic warps; the fixing wires and the elastic warps are distributed along the axial direction of the outer sleeve; the warps and the fixing wires are respectively interwoven with the wefts; the length of the fixing wires is larger than that of the warps under a nature state; the maximum extension length of the warps is identical to that of the fixing wires. The extensible pipe has the advantage that the outer sleeve is not wrinkled under the natural state.

Description

technical field [0001] The invention belongs to the field of flexible pipes and relates to a telescopic pipe. Background technique [0002] The water pipe is used to connect the fixed faucet and the water gun. The existing water pipe is an ordinary hose with a fixed length. Therefore, in order to meet the demand, the length of the general water pipe will be longer than the actual use, which leads to the storage of the water pipe. ,inconvenient. [0003] In order to solve the above problems, the Chinese patent discloses a new type of telescopic water pipe [authorized announcement number CN202733225U], which includes a latex inner pipe and a high-strength wire braided outer pipe. In this patent, the inner tube will elongate radially and axially under pressure, the outer tube is non-elastic, and the diameter of the outer tube is fixed, so the elongation of the inner tube in the radial direction will be limited during use. Therefore, it will only be stretched in the axial dire...

AI Technical Summary

Problems solved by technology

In this patent, the inner tube will elongate radially and axially under pressure, the outer tube is non-elastic, and the diameter of the outer tube is fixed, so the elongation of the inner tube in the radial direction will be limited during use. Therefore, it will only be stretched in the axial direction. In order to satisfy that the inner tube is always located in the outer tube after being stretched, the length of the outer tube must be the same as the length of the stretched inner tube, so that the outer tube must be folded when the water storage tube is not in use. , stored in a wrinkled shape, which makes the product look unattractive and affects sales. At the same time, the wrinkles will hide dirt, making the outer tube easy to get dirty and difficult to clean
