Description

Technical Field

[0001] The utility model relates to the field of water pipes, in particular to a telescopic water pipe. Background Art

[0002] A water pipe, a pipeline for water supply and circulation, is a common item in people's daily life. Since most water taps are installed at fixed locations and cannot change the water outlet position, water pipes are connected to the water taps for use. In order to meet people's different usage requirements for water pipes, water pipes on the market have different lengths. When it is necessary to wash immovable items such as the ground and cars with water, a longer water pipe is needed to connect to the water tap and hold the water pipe for washing. Telescopic water pipes have been invented on the market, and common telescopic water pipes are usually corrugated pipes.

[0003] For the existing telescopic water pipe, the whole is a corrugated pipe. When the water pressure is too high, it may cause the water pipe to break, bringing an unpleasant usage experience to users. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a telescopic water pipe. To solve the above technical problems, the utility model provides the following technical solutions.

[0005] A telescopic water pipe includes a pipe body. The pipe body includes an inner telescopic pipe and an outer telescopic pipe. The outer telescopic pipe is wrapped around the outside of the inner telescopic pipe. The inner telescopic pipe is composed of several corrugated pipes and elastic materials combined in the longitudinal direction. The elastic materials include corrugated pipes and glue layers. The corrugated pipes are longitudinally separated and disconnected, and the glue layers are located at the intervals where the corrugated pipes are separated and disconnected, improving the telescopic property of the inner layer, enhancing the anti-burst property of the inner layer, reducing the possibility of brittle bursting under water pressure, and improving the adhesion strength between the inner and outer layer materials. Through various structures, such as the combination of waves and solids, while enhancing the telescopic performance of the water pipe, the service life of the water pipe is improved.

[0006] Further, the corrugated pipes and the glue layers are integrally formed.

[0007] Further, the corrugated pipes include plastic corrugated pipes.

[0008] Further, the glue layers include elastic materials or rubber glue layers.

[0009] Further, the glue layers include elastic materials or rubber glue layers.

[0010] Further, the inner surface of the outer telescopic pipe is provided with a lower corrugated surface, and the outer surface of the inner telescopic pipe is provided with an upper corrugated surface adapted to the lower corrugated surface.

[0011] Further, a joint is provided at the end of the pipe body. A connecting pipe extending outward is provided on one side of the joint, and the pipe body is sleeved on the connecting pipe.

[0012] Furthermore, the diameter of the connecting pipe is slightly larger than the inner diameter of the pipe body.

[0013] Furthermore, a raised threaded portion is provided on the connecting pipe.

[0014] Compared with the prior art, the beneficial effects that the present utility model can achieve are as follows:

[0015] The inner telescopic pipe of the present utility model is composed of several elastic materials combined in the longitudinal direction. The elastic materials include corrugated pipes and rubber layers. The corrugated pipes are longitudinally separated and disconnected, and the rubber layers are located at the intervals where the corrugated pipes are separated and disconnected, with the corrugated pipes and rubber layers being distributed at intervals. Conventional water pipes are usually entirely made of corrugated pipes, and are prone to breakage when the water pressure is too high. The corrugated pipes include plastic corrugated pipes, which achieve telescoping through the opening of multiple folds, and the rubber layers include rubber rubber layers, which achieve telescoping through the elasticity of their own materials. The inner telescopic pipe of this design is composed of corrugated pipes and rubber layers. Since the stress that the rubber layer can withstand and its own elasticity can produce a large range of deformation, when the water pressure is too high, the inner telescopic pipe can expand even more, effectively avoiding the breakage of the water pipe and ensuring a good user experience.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1-8 shown, a telescopic water pipe includes a pipe body 1. The pipe body 1 includes an inner telescopic pipe 2 and an outer telescopic pipe 3. The outer telescopic pipe 3 is wrapped outside the inner telescopic pipe 2. During use, water flows into the inner telescopic pipe 2, and the pipe body 1 expands and contracts under water pressure. The outer telescopic pipe 3 is made of an elastic material, and the outer telescopic pipe includes a soft rubber outer telescopic pipe. During use, the inner telescopic pipe 2 and the outer telescopic pipe 3 expand and contract synchronously. When water flows into the pipe body 1, the pipe body 1 elongates under the impact of water pressure. The greater the water pressure, the longer the inner telescopic pipe 2 and the outer telescopic pipe 3 extend. The smaller the water pressure, the less the inner telescopic pipe 2 and the outer telescopic pipe 3 extend. When the water injection into the pipe body 1 stops, the water pressure decreases, and the inner telescopic pipe 2 and the outer telescopic pipe 3 retract under their own resilience. When not in use, the pipe body 1 is in a contracted state, with a small volume and light weight, which is convenient for users to carry when going out.

[0027] The inner telescopic pipe 2 is composed of several elastic materials combined in the longitudinal direction. The elastic materials include a corrugated pipe 4 and a glue layer 5. The corrugated pipe 4 is longitudinally separated and disconnected, and the glue layer 5 is located at the interval where the corrugated pipe 4 is separated and disconnected. A glue layer 5 is provided between every two sections of the corrugated pipe 4. The corrugated pipe 4 includes a plastic corrugated pipe and realizes expansion and contraction through the opening of multiple folds; the glue layer 5 includes a rubber glue layer and a latex glue layer, which have good elasticity and realize expansion and contraction through the elasticity of their own materials. In traditional water pipes, usually the whole pipe is a corrugated pipe. Compared with traditional water pipes, the inner telescopic layer 2 of this design is composed of multiple longitudinal corrugated pipes 4 and glue layers. Since the stress that the glue layer 5 can bear and its own elasticity can produce a large range of deformation, when the water pressure is too high, the water pipe can expand thicker. The glue layer 5 is not easily broken compared with the corrugated pipe 4. Therefore, it can effectively prevent the water pipe from breaking and ensure a good user experience for users.

[0028] The corrugated pipe 4 and the glue layer 5 are integrally formed, avoiding connection structures, increasing strength, and also facilitating production.

[0029] The inner surface of the outer telescopic pipe is provided with a lower corrugated surface 7, and the outer surface of the inner telescopic pipe 2 is provided with an upper corrugated surface 6 adapted to the lower corrugated surface 7. The upper corrugated surface 6 and the lower corrugated surface 7 are mutually attached, which can further increase the contact area between the outer telescopic pipe 3 and the inner telescopic pipe 2, increase the friction force, make the inner telescopic pipe 2 and the outer telescopic pipe fit more closely, and are not easily separated.

[0030] A joint 8 is provided at the end of the pipe body 1. The joint 8 is for installation on a faucet. A connecting pipe 9 extending outward is provided on one side of the joint 8. The pipe body 1 is sleeved on the connecting pipe 9. The diameter of the connecting pipe 9 is slightly larger than the inner diameter of the inner telescopic pipe 2. When the pipe body 1 is sleeved on the connecting pipe 9, it can rely on the elasticity of the pipe body itself to expand it, making the connection more tight.

[0031] A raised threaded portion 10 is provided on the connecting pipe 9, which increases the contact surface with the pipe body, increases the friction force, and also further expands the pipe body 1, further increasing the connection strength between the connecting pipe and the pipe body 1, and preventing the pipe body 1 from falling off during use and bringing an adverse experience to the user.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
