Example Embodiment

[0018] The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the invention, but the present invention is not limited to these embodiments.

[0019] Such as Figure 1-3 Shown. A single-layer telescopic tube includes a braided tube 1. A plurality of elastic wires 2 arranged along the axial direction of the braided tube 1 are provided on the braided tube to form an elastic braided tube capable of axial expansion and contraction. The inner or / A rubber layer formed by dipping is provided on the outer surface, that is, a rubber dipping tube, or a rubber lining layer 3 is provided on the inner tube wall of the elastic braided tube. The dipped elastic braided tube and the elastic braided tube provided with the rubber lining 3 still have the ability of axial expansion and contraction. And through the means of dipping and lining, the elastic braided tube is formed into a tube that can transp...

Abstract

The invention belongs to the technical field of water pipes, in particular to a single-layer extension pipe, and solves the technical problem of short service life caused by friction between an inner pipe and an outer pipe during extending. The single-layer extension pipe comprises a weaving pipe; the weaving pipe is provided with multiple elastic weaving pipes formed by elastic wires arranged in the axial direction of the weaving pipe and capable of extending in the axial direction; glue layers, namely glue dipping pipes formed by glue dipping are arranged on the inner or/and outer surfaces of the elastic weaving pipes; or glue lining layers are arranged on the inner pipe walls of the elastic weaving pipes. The elastic weaving pipes are dip in glue or provided with the glue lining layers to form a water pipe capable of conveying liquid, and are combined with the elastic wires to achieve axial extension, so that the friction force between the inner pipe and the outer pipe of the extension water pipe in the prior art can be prevented, and the service life is prolonged; and the single-layer extension pipe is beautiful in appearance, reduces the production cost, and simplifies the production process.

Description

technical field [0001] The invention belongs to the technical field of water pipes, in particular to a single-layer telescopic pipe. Background technique [0002] Water pipes are used to transport liquids. The earliest water pipes were generally plastic pipes. This kind of water pipe cannot be stretched, and different distances require water pipes of different lengths. The long water pipes are scattered on the ground causing disorder, and at the same time, it is also very inconvenient when winding. In addition, the plastic pipe is easily damaged and has a short service life when it is trampled on the ground or rolled over by vehicles. [0003] In order to improve the above phenomenon, people have developed telescopic water pipes. A kind of telescopic water pipe that is announced as the utility model patent of CN204852708 U as notification number. The telescopic water pipe includes an inner pipe and an outer pipe, and both ends of the inner pipe and the outer pipe are co...
