Abstract

The invention provides a switching device. The switching device comprises a rotatable valve rod, an outer sleeve piece arranged outside the rotatable valve rod in a sleeving mode and a hose connector connected to the rotatable valve rod in a sleeving mode. The rotatable valve rod is provided with a first end and a second end, a water inlet hole is formed in the first end of the rotatable valve rod, a water outlet flow channel communicating with the water inlet hole is formed in the rotatable valve rod from the first end to the second end, and the interior of the hose connector communicates with the water outlet flow channel. A water inlet plug is connected to the first end of the rotatable valve rod, and a plugging cavity matched with the water inlet plug is formed in the outer sleeve piece. A first internal thread section is formed on the inner wall of the outer sleeve piece, and a first external thread section matched with the first internal thread section is formed on the outer wall of the middle of the rotatable valve rod. The end, close to the second end, of the rotatable valve rod is rotationally arranged on the hose connector in a sleeving mode, and a rotation positioning structure is arranged between the hose connector and the rotatable valve rod. The switching device has the advantages that the number of used parts is small, the cost can be reduced, and installation and use are very convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of valves, in particular to an adapter device. 【Background technique】 [0002] When the house is decorated, the water inlet pipe will be embedded in the wall, and the water outlet will be set on the wall. Water outlets will need to be set on the walls of places such as toilets and kitchens. In order to control the water outlet conveniently during use, an angle valve will be installed at the water outlet for switching. The angle valve is connected to the water outlet components such as faucets, water heaters, and toilets through hoses, and controls whether to supply water to the water outlet components through the angle valve. Existing angle valves are all controlled by a valve core installed in the angle valve, and ceramic sheets need to be installed inside the valve core to achieve sealing. Therefore, the existing angle valves have the problems of many parts, high cost, and inconvenient installation. In ...
