Description

Technical Field

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

[0002] Water pipes and gas pipes, which are pipes for water and gas circulation, are common daily necessities for people. In order to meet people's different usage requirements for water and gas pipes, water pipes on the market have different lengths. When it is necessary to wash the ground with water or use the gas pipe to dust the car and encounter items that are not easy to move, a longer water or gas pipe is needed to connect to the water or gas outlet and hold the pipe to wash. To facilitate people's use, telescopic water pipes have been invented on the market.

[0003] When the water pressure of the existing telescopic water pipe is too high, it may cause the bursting of the water pipe. The quality of the water pipe is relatively ordinary and its service life is also short. Content of the Utility Model

It is characterized in that a spring layer is provided between the outer telescopic layer and the inner telescopic layer. The spring layer is uniformly arranged between the outer telescopic layer and the inner telescopic layer along the water flow direction. The spring layer is wrapped by a linear material outside the inner layer. The spring layer restricts the inner layer from expanding and elongating, and the outer layer protects the spring layer from being worn out when exposed.

[0006] Further, the three layers of the inner telescopic layer, the spring layer, and the outer telescopic layer include being completely compounded and adhered together, and the three layers of the inner telescopic layer, the spring layer, and the outer telescopic layer also include being separately combined and sleeved together.

[0007] Further, a first limiting concave surface is provided between the spring layer and the outer telescopic layer.

[0008] Further, a second limiting concave surface is provided between the spring layer and the inner telescopic layer.

[0016] Further, a raised threaded portion is provided on the connecting pipe.

[0017] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0018] A spring layer is provided between the outer telescopic layer and the inner telescopic layer of the present utility model. The spring layer is wound and wrapped around the outer side of the inner telescopic tube by linear objects. The spring layer restricts the telescopic movement of the inner telescopic tube, and the outer telescopic tube protects the spring layer from external wear. When water flows through the inner telescopic layer, it will cause the inner telescopic layer to expand. If the water pressure is too high, it may cause the rupture of the inner telescopic layer. Wrapping the spring layer around the outer side of the inner telescopic tube plays a protective role, which can effectively prevent the water pipe from breaking and increase the service life of the tube.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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.

[0031] As Figures 1-10 shown, a telescopic water and gas pipe includes a pipe body 1. The pipe body 1 includes an inner telescopic layer 2 and an outer telescopic layer 3. The outer telescopic layer 3 is wrapped outside the inner telescopic pipe 2. During use, water and gas flow into the inner telescopic layer 2, and the pipe body 1 expands and contracts due to water pressure. As the water and gas flow impacts, the pipe body 1 will expand and contract. After the water is discharged, the pipe body 1 can contract, reducing the occupied volume and facilitating the user to carry it when going out. A spring layer 4 is provided between the outer telescopic pipe 3 and the inner telescopic layer 2. The spring layer 4 is evenly arranged between the outer telescopic layer 3 and the inner telescopic layer 2 along the water flow direction. The spring layer 4 is wrapped outside the inner telescopic layer 2 by wire-like objects. The spring layer 4 restricts the expansion and contraction of the inner telescopic layer 2, and the outer telescopic layer 3 protects the spring layer 4 from being worn out. When water and gas flow through the inner telescopic layer 2, it will cause it to expand. If the water pressure is too high, it may cause the inner telescopic layer 2 to rupture. Wrapping the spring layer 4 outside the inner telescopic layer 2 plays a protective role, which can effectively prevent the water and gas pipe from breaking and increase the service life of the pipe.

[0032] The spring layer 4 includes a metal wire spring, a plastic spring, and a chemical fiber expansion net. While having good elasticity, it also has sufficient hardness to better protect the inner telescopic layer 2 and prevent the inner telescopic pipe 2 from expanding greatly due to a large water pressure impact and bursting.

[0033] Since the spring layer 4 is in a spring shape, in order to facilitate better fitting of the three-layer structure of the telescopic layer 2, the spring layer 4 and the outer telescopic layer 3, a first limiting concave surface 5 is provided between the spring layer 4 and the outer telescopic layer 3, and a second limiting concave surface 6 is provided between the spring layer 4 and the inner telescopic layer 2. The first limiting concave surface 5 and the second limiting concave surface 6 are a plurality of evenly distributed arc surfaces adapted to the profile of the spring. Through the cooperation of the first limiting concave surface 5, the second limiting concave surface 6 and the elastic telescopic layer 4, the inner telescopic layer 2 and the outer telescopic layer 3 can be prevented from being misaligned during use, thereby ensuring a good user experience.

[0034] The outer telescopic layer 3 comprises an elastic woven mesh, which has good elasticity and a good hand feel, thereby enhancing the hand feel of the user in gripping the water pipe.

[0035] The inner telescopic layer 2 includes an elastic tube, a shrink film, and a chemical fiber cloth, and has good elasticity. When flowing water or gas passes through the inner telescopic layer 2, the inner telescopic layer 2 can be deformed, stretched or expanded. After the water or gas is discharged, the inner telescopic layer 2 shrinks due to the resilience of its own material.

[0036] The end of the tube body 1 is provided with an interface 7, which is used to be installed on a water outlet or an air outlet. A connecting pipe 8 extending outward is provided on one side of the interface 7. The tube body 1 is sleeved on the connecting pipe 8. The diameter of the connecting pipe 8 is slightly larger than the inner diameter of the inner telescopic tube 2. When the tube body 1 is sleeved on the connecting pipe 8, it can be expanded by relying on the elasticity of the tube body itself, so that the connection is tighter.

[0037] The connecting pipe 8 is provided with a raised threaded portion 9 to increase the contact surface with the pipe body, increase the friction, and further stretch the pipe body 1, further increasing the connection strength between the connecting pipe and the pipe body 1, preventing the pipe body 1 from falling off during use and causing a bad experience for the user.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
