Telescopic water pipe strengthening structure

Abstract

The utility model discloses a telescopic water pipe strengthening structure which comprises an inner pipe and an outer pipe. The inner pipe has radial expansion and contraction and axial expansion and contraction elasticity. The outer tube is movably connected to the periphery of the inner tube in a sleeved mode, and a plurality of elastic warp yarns and non-elastic weft yarns are woven into a tubular fabric. Each elastic warp yarn comprises at least one elastic warp yarn and at least one non-elastic covering yarn; wherein the non-elastic covering yarn is spirally wound and covered on the peripheral side of the elastic warp yarn along the extending direction of the elastic warp yarn. By means of the structure, the inner pipe can stretch out and draw back in the axial direction due to the existence of water pressure, and meanwhile the non-elastic wrapping threads effectively prevent the elastic warp yarn from making direct contact with sunlight.

Description

Technical Field

[0001] This utility model relates to the technical field of water diversion equipment, particularly to a reinforced structure for a telescopic water pipe that can extend and retract axially in response to water pressure and is specifically designed to block sunlight. Background Technology

[0002] Axially expandable water pipes consist of a retractable, elastic inner tube covered by a non-elastic braided outer tube. As the inner tube expands or contracts, the braided outer tube also changes shape, retracting into a wrinkled form. However, this wrinkled outer tube has a drawback: when the pipe retracts, the outer diameter of the braided outer tube increases significantly, making winding difficult and resulting in an unsightly appearance. Furthermore, the wrinkled areas are prone to deformation during repeated expansion and contraction, becoming weak points that may crack. If the crack widens, it will affect the contractility of the inner tube, causing uneven internal water pressure and increasing the risk of the inner tube wall bursting under water pressure.

[0003] In addition, axially expandable water pipes are typically used for outdoor water supply and are often rolled up and left outdoors after use. To keep the pipes dry, these types of pipes are often exposed to sunlight for extended periods.

[0004] For axially expandable water pipes, long-term exposure to ultraviolet radiation can easily lead to aging and embrittlement, causing the pipes to be unable to expand and contract normally, or even become tangled. Utility Model Content

[0005] In view of the problems and deficiencies of the prior art, one objective of this utility model is to address the problems of aging and embrittlement of woven components caused by the lack of a shielding structure.

[0006] The present invention aims to solve the problem of the reinforced structure of telescopic water pipes being easily damaged by ultraviolet radiation.

[0007] To achieve the above objectives, a reinforced telescopic water pipe structure is proposed, comprising an inner tube and an outer tube. The inner tube possesses radial expansion and contraction elasticity as well as axial expansion and contraction elasticity. The outer tube, movably sleeved around the inner tube, is a tubular fabric woven from a plurality of elastic warp yarns and non-elastic weft yarns. Each elastic warp yarn includes at least one elastic warp thread and at least one non-elastic covering thread; wherein the non-elastic covering thread spirally wraps around the outer periphery of the elastic warp yarn along its extension direction. Through this structure, the inner tube can axially expand and contract according to the presence or absence of water pressure, while the non-elastic covering thread effectively blocks direct contact between the elastic warp yarns and sunlight.

[0019] like Figures 1 to 5 The present invention relates to a telescopic water pipe reinforcement structure, comprising an inner pipe 10 and an outer pipe 20 covering the outer periphery of the inner pipe 10.

[0020] The inner tube 10 has radial expansion and contraction and axial extension and contraction elasticity, and its material is selected from (including but not limited to) latex and thermoplastic elastomer (TPE).

[0021] The outer tube 20 is a tubular braided fabric, which is formed by a high-speed braiding machine in conjunction with the outer contour of the inner tube 10, and can be movably disposed on the outer periphery of the inner tube 10.

[0022] Furthermore, the outer tube 20 is woven from a plurality of elastic warp yarns 21 and a plurality of non-elastic weft yarns 22. Each elastic warp yarn 21 is parallel to the axial direction of the inner tube 10. Also, each non-elastic weft yarn 22, along the outer wall of the inner tube 10, passes through each elastic warp yarn 21 in a forward spiral S-shape and a reverse spiral S-shape, and sequentially interlaces and twists each elastic warp yarn 21.

[0023] Each elastic warp yarn 21 comprises at least one elastic warp yarn 211 and at least one non-elastic covering yarn 212.

[0024] The aforementioned elastic warp yarns 211 are configured according to the elasticity requirements of the axial extension of the inner tube 10, and the number of elastic warp yarns 211 is not limited to one but can be more as needed, so that they are arranged in parallel, stacked or braided into strands.

[0025] The aforementioned non-elastic covering thread 212 spirally wraps around the outer periphery of the elastic warp yarn 211 along the extension direction of the elastic warp yarn 211, thus isolating the contact area between sunlight (ultraviolet rays) and the elastic warp yarn 211.

[0026] The above is an introduction to the components and assembly method of the telescopic water pipe reinforcement structure of a preferred embodiment of the present invention. The operating features of the embodiment of the present invention will be introduced below.

[0027] The inner tube 10 of this utility model's telescopic water pipe reinforcement structure can axially expand and contract according to the presence or absence of water pressure in the inner tube 10. The outer tube 20 forms a radial restraint force on the inner tube 10, ensuring that the expansion and contraction of the inner tube 10 is within a reasonable range. In addition, the elastic warp yarn 21 allows the outer tube 20 to cooperate with the inner tube 10 in axial extension and contraction.

[0028] The above description is only a preferred embodiment of the present utility model and is intended to clarify the features of the present utility model. It is not intended to limit the scope of the embodiments of the present utility model. Equivalent changes made by those skilled in the art based on the present utility model, as well as changes known to those skilled in the art, should still fall within the scope of the present utility model.
