The invention discloses an inner joint with a water switch function, which comprises an inner joint main body, the water inlet end of the inner joint main body is connected with a water inlet pipe, the water outlet end of the inner joint main body is in threaded connection with a nut on a water inlet of a water outlet pipe, and a flowing hole is formed in an inner cavity of the inner joint main body; the inner joint also comprises a plug sleeve, a guide rod and a piston, wherein the plug sleeve is movably sleeved on a water outlet in the inner cavity of the inner joint main body, and a flow guide hole is formed in the plug sleeve; a convex ring is arranged on one end surface of the plug sleeve facing to the nut, a sleeve wall is arranged at the other end of the plug sleeve, and the tail end of the sleeve wall and the inner cavity wall of the inner joint main body form a sealing state; and the guide rod is arranged in a guide hole in the axis position of the plug sleeve in a penetrating way and is fixedly connected with one end of the piston; and the other end of the piston is a conical part, the big end of the conical part faces to the water inlet end of the inner joint main body, and a flowing hole is arranged in the conical part in a penetrating way. The inner joint has the benefits that water cut-off and water conduction states of the inner joint can be switched only through rotating the nut on the water inlet of the water outlet pipe, and the use is very convenient.
Description
technical field [0001] The invention relates to the field of internal joints, in particular to an internal joint with the function of a water switch. Background technique [0002] As a commonly used connecting piece, pipe fittings are widely used in daily life. However, the existing internal joint is only used to connect two internally threaded pipe fittings with the same nominal diameter, and the internal joint has no other functions, and the function is too single. Contents of the invention [0003] The object of the present invention is to provide an inner joint with a simple structure and convenient use with the function of a water switch. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An inner joint with the function of a water switch, comprising an inner joint body, the water inlet end of the inner joint body is connected to a water inlet pipe, the water outlet end of the inner joint body is threaded w...
