In order to solve the above-mentioned problems, there has been proposed a series of telescopic water pipe products, such as US patent 8479776B2, a flexible garden hose having an inner pipe member made of an elastic material and an elastic outer layer member made of an inelastic material, the inner pipe member being fixed to the elastic outer layer member only at an inlet connector and an outlet connector, the inlet connector being configured to be fixed to a water supply provided from a conventional household faucet, the outlet connector being coupled to a restrictor, allowing the inner pipe member to be pressure-balanced with pressurized water received from the water supply, the pressurized water longitudinally elongating the elongated inner pipe member along the length of the inner pipe member and expanding the diameter of the inner pipe member, thereby achieving an increase in the length and diameter of the water pipe; when the faucet is turned off, the length and diameter of the hose are reduced by the elastic inner tube, and the hose is contracted to an original state. The water pipe that this patent adopted can elasticity flexible, like this when the water injection that has the water pressure in to flexible water pipe, flexible water pipe can realize the inflation, and then change length and diameter, but this water pipe has strong friction tearing when inflation and shrink between outer cloth cover and the inner tube, leads to the water pipe damage, and life is limited.

In this embodiment, the telescopic water pipe has a structure of an elastic braid, and the elastic braid has only the telescopic capability in the length direction, and can be used for limiting the elastic expansion of the elastic inner pipe in the diameter direction when the elastic inner pipe is acted by water pressure, so that the water pipe is only elongated in the length direction, but not enlarged in the diameter direction, and the influence on the service life due to the strong friction with the outer cloth cover is avoided. In addition, an outer cloth sleeve is arranged outside the elastic inner tube and the elastic braiding layer, and the length of the outer cloth sleeve is longer than the limit length of the elastic inner tube and the elastic braiding layer; and when the elastic inner tube is used under the limiting water pressure, the diameter of the inner wall surface of the outer cloth sleeve is larger than the diameters of the elastic inner tube and the elastic braiding layer, so that the inner wall surface of the outer cloth sleeve can not generate strong friction with the elastic inner tube and the elastic braiding layer in the use process so as to influence the service life. In addition, the outer cloth sleeve is used as a protective layer, so that the elastic inner tube and the elastic woven layer can be prevented from being broken due to sunlight exposure and abrasion of sand, stones, branches and the like, and the service life of the elastic woven layer is prolonged. The outer cloth cover can be provided with various patterns and designs, so that the product style is more various, and the aesthetic degree of the product is improved.
Fig. 9 to 12 are partial enlarged views of the above embodiment in order to better explain the change of the structure of the inside of the outer cloth cover in the absence and presence of water pressure.
Fig. 9 and 10 are views showing the state of the tube body consisting of the elastic inner tube 4, the elastic braid 3 and the elastic inner tube 2, respectively, when not stretched and elongated; as can be seen from fig. 9 and 10, the tube structure is elongated only in the longitudinal direction and has a slightly reduced diameter without increasing in diameter under the action of the elastic braid in the presence of water pressure.
Fig. 11 and 12 are views of the elastic inner tube 4 and the elastic braid 3, respectively, when not stretched and elongated; as can be seen from fig. 11 and 12, the elastic inner tube is elongated only in the longitudinal direction by the elastic braid under the hydraulic pressure, and the diameter is not increased but slightly reduced.
As can be seen from fig. 9-12, the structural design of the elastic braid limits the diameter increase of the elastic inner tube and achieves length extension and shortening.
Fig. 13 and 14 are schematic sectional views at the extreme water pressure state.
In fig. 13, the elastic outer layer is set in a sectional view at the limit water pressure, and a gap is formed between the elastic outer layer and the outer cloth cover, and in fig. 14, the elastic outer layer is not set in a sectional view at the limit water pressure, and a gap is also formed between the elastic outer layer and the elastic inner tube and the elastic braid. Therefore, the inner wall surface of the outer cloth sleeve can not generate strong friction with the elastic outer layer or the elastic inner tube and the elastic braiding layer in the use process of the whole water pipe so as not to influence the service life; in addition, the outer cloth sleeve is used as a protective layer, so that the elastic outer layer, the elastic woven layer and the elastic inner tube can be prevented from being broken due to sunlight exposure and abrasion of sand, stones, branches and the like, and the service life is prolonged. The outer cloth cover can be provided with various patterns and designs, so that the product style is more various, and the aesthetic degree of the product is improved.
The utility model provides a structure of an elastic braid and an outer cloth cover regardless of the telescopic water pipe. The elastic braiding layer only has the expansion capability in the length direction, and can be used for limiting the elastic expansion of the elastic inner tube in the diameter direction when the elastic inner tube is acted by water pressure, so that the water tube is only elongated and shortened in the length direction, but not increased in the diameter direction, and the service life is prevented from being influenced by the strong friction between the elastic braiding layer and the outer cloth sleeve. In addition, an outer cloth sleeve is arranged outside the elastic inner tube and the elastic braiding layer, and the length of the outer cloth sleeve is longer than the limit length of the elastic inner tube and the elastic braiding layer; and when the elastic inner tube is used under the limiting water pressure, the diameter of the inner wall surface of the outer cloth sleeve is larger than the diameters of the elastic inner tube and the elastic braiding layer, so that the inner wall surface of the outer cloth sleeve can not generate strong friction with the elastic inner tube and the elastic braiding layer in the use process so as to influence the service life. In addition, the outer cloth sleeve is used as a protective layer, so that the elastic inner tube and the elastic woven layer can be prevented from being broken due to sunlight exposure and abrasion of sand, stones, branches and the like, and the service life of the elastic woven layer is prolonged.
