Soft and pressure self-expanding water hose switch connector

Abstract

The invention discloses a soft and pressure self-expanding water hose switch connector, which comprises a soft hose (2), a pressure self-expanding water hose (1), hose hoops (6), a switch (15), a connector (11) and a double-controlled valve (12) with a rotary sprinkler head and water outlets. An assembly method for the soft and pressure self-expanding water hose switch connector comprises the following steps of leading an inner pipe by using a long steel wire to penetrate into an outer pipe, lengthening the internal high-elasticity pressure self-expanding water hose, and assembling to form a soft and pressure self-expanding water hose. When no water flows, the internal high-elasticity pressure self-expanding water hose is normally shrunk, and the external soft hose (2) is zigzag, and when the water flows, the internal high-elasticity pressure self-expanding water hose (1) is expanded, and the external soft hose (2) is almost equal to the internal high-elasticity pressure self-expanding water hose (1) in length so as to greatly reduce the storage size. As the soft and pressure self-expanding water hose switch connector is light and small, so that a pipeline winder or a hose car which is bigger in size and heavier is not used in certain occasions.

Description

technical field [0001] The invention relates to a valve device, a soft water pipe and a switch connector for gardening, gardening, cleaning or cooling, especially a soft and pressure self-expanding soft water pipe switch connector. The switch connector includes a rotating sprinkler head and The utility model relates to a double-control valve for a water outlet, which belongs to the technical field of garden irrigation gas-liquid switches and water injection devices, pipeline winders and water pipe trucks. Background technique [0002] Gardening, gardening, and cleaning are inseparable from hose hoses. Usually, a pipeline reel with a damping device or a water hose truck is used, which are relatively large in size and heavy in weight. Existing garden hose carts for storing flexible pipes or cables are moved by the operator pushing the handle. But the handfeel of existing metal handle is relatively poor; If the plastic protection tube will be set outside the curved metal hand...

AI Technical Summary

Problems solved by technology

If you engage in electronic valves, you will need a power supply, and the electronic components are prone to failure.

It is best to have a valve that is purely mechanical, compact in structure, low in cost, and saves maintenance without electricity. At the same time, many customers require the production of a valve with a rotating sprinkler head and water outlet. The double control valve, which is easier said than done, is also a long unresolved blank problem in this field
