Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of telescopic water pipe, concretely to a telescopic water pipe with valve. BACKGROUND

[0002] The existing telescopic water pipe on the market is mostly composed of inner core elastic tube and outer protective sleeve, and the elastic tube is made of latex, rubber or TPR thermoplastic elastomer as raw material. Because of its high elasticity, when the pressure water of 3-10 kg is connected, the radial water area and longitudinal length of the elastic tube can be expanded and extended by 2-4 times under the protection of the outer protective sleeve. When the pressure water source is turned off, the telescopic water pipe can quickly discharge the residual water in the tube under the rebounding force of the inner core elastic tube, and return to the original product size, which is convenient to use and is loved by domestic and foreign customers.

[0003] However, the existing telescopic water pipe is usually directly connected with the spray head. After spraying is completed, the water flow needs to be closed at the water source, which is not convenient to use, and a lot of water resources are wasted. In addition, the elastic tube made of latex and rubber is relatively soft, and it is easy to be pierced by external objects during dragging. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a telescopic water pipe with valve to solve the problems in the background art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a telescopic water pipe with valve, comprising an inner tube, a telescopic cloth sleeve, a valve and a connecting assembly. The wall surface of the inner tube is composed of continuous wave crests and wave troughs, which allows the inner tube to contract and expand without permanent deformation. The inner tube is wrapped with a telescopic cloth sleeve, which can return to its original length after stretching. One side of the inner tube is provided with a valve, and the other side of the inner tube is provided with a connecting assembly.

[0006] Preferably, a protective film is arranged between the inner tube and the telescopic cloth sleeve.

[0007] Preferably, a reflective piece is arranged in the middle of the telescopic cloth sleeve. The reflective piece is composed of two arc plates with the same structure, and the two arc plates are detachably connected.

[0008] Preferably, the valve comprises a valve body, a ball, a handle, a connecting pipe one and a sheath one. The ball is rotatably connected inside the valve body. The valve body is provided with a valve rod extending out of the valve body at the top end of the ball, and the handle is bolted to the valve rod at the top end of the ball. The left side of the connecting pipe one is threadedly connected with the right end inside the valve body. The inner tube, the telescopic cloth sleeve and the protective film are sequentially overlapped and sleeved on the right side surface of the connecting pipe one, and the inner tube, the telescopic cloth sleeve and the protective film are fixed to the connecting pipe one by riveting. The sheath one is threadedly connected to the right side surface of the valve body.

[0009] Preferably, the connecting assembly includes a threaded head, a connecting tube 2 and a sheath 2, the left side of the threaded head is threadedly connected to the connecting tube 2, the inner tube, the telescopic cloth sleeve and the right end of the protective film are overlapped and sleeved on the left side surface of the connecting tube 2 in sequence, and the inner tube, the telescopic cloth sleeve and the protective film are fixed to the connecting tube 2 by riveted parts, and the sheath 2 is threadedly connected to the left side surface of the threaded head.

[0010] Preferably, the right end of the first sheath covers the surface of the connection between the inner tube, the telescopic cloth sleeve and the left end of the protective film, and the left end of the second sheath covers the surface of the connection between the inner tube, the telescopic cloth sleeve and the right end of the protective film.

[0011] Preferably, a groove is provided on the side surface of the valve stem at the top end of the sphere, and a sealing ring is sleeved in the groove.

[0012] Preferably, the sphere is spherical, and a through hole is provided at the middle end of the sphere.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting up a valve, the handle can be turned, and the handle will drive the sphere to rotate synchronously, so that the through hole in the middle of the sphere is opposite to the connecting pipe. At this time, water can enter the sprinkler head for spraying. After spraying, just turn the handle in the opposite direction to reset it, and the water flow can be blocked again. The operation is simple, and there is no need to return to the water source, thus avoiding waste of water resources. When water flows through, the folded inner tube will be stretched due to pressure, and the telescopic cloth cover on the outside will be stretched synchronously. When the water source is closed, the telescopic cloth cover will shrink due to elastic force, thereby driving the inner tube to reset and fold. Not only can the telescopic effect of the water pipe be achieved, but the hardness of the material of the inner tube itself is relatively high. Combined with the telescopic cloth cover covering the surface of the inner tube, the overall wear resistance of the water pipe can be improved. The protective film can enhance the dustproof effect of the inner tube surface. The reflective member can emit light at night, making it easier for pedestrians to find the water pipe.
