Description

Technical Field

[0001] The utility model relates to a hose. Background Art

[0002] As a commonly used water conveying part in daily life, the hose is used in various aspects of daily life such as watering flowers, washing cars, and sprinkling water. The span of the hose is generally long during use, resulting in a large volume after storage. In addition, since the accumulated water in the hose is not easy to be discharged, the weight of the hose will be increased, and the accumulated water in the hose will easily stink. In order to solve the above problems, a telescopic hose with announcement number CN220354694U is made by bonding an elastic inner tube, a mesh braided layer, a wear-resistant outer tube, and a pleated outer jacket. The telescopic hose can expand in the length direction due to the water pressure after water is passed through it, and when the water injection is stopped, the remaining water in the hose can be quickly discharged due to the rebound effect of the elastic tube, and the product shrinks to the original size, which is convenient to use. However, such telescopic water hoses are easily damaged during use due to the intense friction and tearing between the inner tube and the outer sleeve. After the telescopic water hose is connected to a pressurized water source, the inner elastic tube of the telescopic water hose expands rapidly, generating strong friction and tearing forces with the pleated outer sleeve. During the process of retraction after the pressurized water source is turned off, the inner elastic tube and the outer cloth sleeve will rub against each other again. In addition, during use, sand, branches and other debris passing through the cloth sleeve will cause fatal damage during the expansion, extension and retraction of the water hose. Utility Model Content

[0003] In view of the defects of the existing hoses, the technical problem to be solved by the utility model is to provide a wear-resistant hose.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, the utility model is realized through the following technical measures: a hose, comprising: an elastic inner tube, the elastic inner tube is hollow inside, a mesh woven layer is woven outside the elastic inner tube, the mesh woven layer limits the lateral expansion of the elastic inner tube and realizes longitudinal expansion, an elastic rubber layer is wrapped outside the mesh woven layer, the elastic rubber layer is fixedly connected to the elastic inner tube, driving the mesh woven layer to expand and contract, a winding layer is provided outside the elastic rubber layer, and the winding layer is covered with a wear-resistant outer tube.

[0005] Furthermore, the inner diameter of the elastic inner tube is preferably 3-15 mm, the thickness is preferably 0.2-2 mm, and the thickness of the elastic rubber layer is preferably 0.2-2 mm.

[0006] Furthermore, the inner diameter of the elastic inner tube is 9.5 mm, the thickness is 1.5 mm, and the thickness of the elastic rubber layer is 1.5 mm.

[0007] Furthermore, the mesh woven layer is a yarn mesh woven layer.

[0008] Furthermore, the yarn mesh braided layer includes any one of the following: a polyester mesh braided layer, a polypropylene mesh braided layer, a nylon mesh braided layer, and an acrylic mesh braided layer.

[0009] Furthermore, the yarn mesh braided layer is formed by oblique braiding of 10D-5000D yarns.

[0010] Furthermore, the elastic adhesive layer is a pve layer, the elastic adhesive layer is cast outside the mesh woven layer, and the elastic adhesive layer covers and penetrates the mesh woven layer to be bonded and adhered to the elastic inner tube.

[0011] Furthermore, the winding layer is a yarn mesh braided layer, and the yarn is 10D-5000D yarn braided in an oblique manner, which further limits the lateral expansion of the elastic inner tube.

[0012] Furthermore, the wear-resistant outer tube is a PVC hose, and the thickness of the wear-resistant outer tube is 5 mm.

[0013] Compared with the prior art, the advantages of the utility model are: the elastic rubber layer can stabilize the mesh woven net, balance the pressure when it expands and contracts, and reduce the friction of the mesh woven net, thereby increasing durability and improving service life. It is easy to drain residual water after storage, and storage is convenient. The wear-resistant outer tube solves the problem that the cloth cover is not wear-resistant and sand and other debris can easily pass through the cloth cover and enter the water pipe.

[0025] The yarn mesh braided layer 4 is formed by oblique braiding of 10D-5000D yarns.

[0026] The elastic adhesive layer 3 is a pve layer, and the elastic adhesive layer 3 is cast outside the mesh woven layer 4 . The elastic adhesive layer 3 covers and penetrates the mesh woven layer 4 and is bonded to the elastic inner tube 5 .

[0027] The winding layer 2 is a yarn mesh braided layer 4 , and the yarn is 10D-5000D yarn woven obliquely, which further limits the lateral expansion of the elastic inner tube 5 .

[0028] The wear-resistant outer tube 1 is a PVC hose, and the thickness of the wear-resistant outer tube 1 is 5 mm.

[0029] The hose of this embodiment can be retracted by 1 to 3 times. After the hose is connected to water, when water flows into the elastic inner tube 5, the elastic inner tube 5 expands due to the water pressure. The elastic inner tube 5 is limited in lateral expansion under the action of the mesh woven layer 4 and the winding layer 2. The elastic inner tube 5 retracts and contracts to drive the elastic rubber layer 3, and the elastic rubber layer 3 drives the mesh woven layer 4 to retract and contract, thereby reducing the friction when the elastic inner tube 5 retracts and contracts.

After the water intake stops, the hose contracts under the elastic force of the wear-resistant outer tube 1, the elastic rubber layer 3, and the elastic inner tube 5, and the remaining water in the tube is discharged as the inner tube shrinks.
