Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, a water inlet and water outlet joint structure includes a water inlet 1, a water outlet 2 and a threaded joint 3. The threaded union 3 includes a nut 4, a flat joint 5 and a sealing washer 6; the nut 4 is tubular, and the circumferential surface of one end of the inner cavity of the nut 4 is provided with threads, and the water inlet 1 and the water outlet 2 are An external thread that matches the nut 4 of the threaded union 3 is provided; a circle of raised inner steps 7 is provided on the other end of the inner cavity of the nut 4; the flat joint 5 is tubular, and the flat joint 5 One end of the outer circumferential surface is provided with a ring of outer steps 8; the outer diameter of the flat joint 5 is in clearance fit with the inner step in the nut 4, and the outer diameter of the outer step 8 on the flat joint 5 is between th...

The invention discloses a water inlet and water outlet connector structure. The water inlet and water outlet connector structure comprises a water inlet, a water outlet and a movable threaded connector, wherein the movable threaded connector is composed of a nut, a flat connector and a sealing gasket, and external threads matched with the nut of the movable threaded connector are arranged on the water inlet and the water outlet. Because the nut and the external threads are screwed in and out, the water inlet and the movable threaded connector can be fast connected and detached, the water outlet and the movable threaded connector can be fast connected and detached, and meanwhile, sealing performance is guaranteed. Compared with an existing metal tube connector on which PTFE thread seal tape needs to be wound, disassembly and assembly are achieved through a spanner, and therefore the water inlet and water outlet connector structure is more convenient and faster to use; meanwhile, a plastic workpiece is low in price and cost is reduced.
Description
technical field [0001] The invention relates to a joint structure of a water inlet and a water outlet. Background technique [0002] A general water treatment device is provided with at least two water inlet and outlet pipes. Raw water flows into the water treatment device from the water inlet, and flows out from the water outlet after a series of treatments. [0003] The water inlet and the water outlet need to be connected with external water pipes, and the existing water inlet and water outlet joint structure utilizes metal pipe joints to realize this function. The water inlet and outlet are provided with threads that match the metal pipe joints. When connecting and assembling, it is first necessary to wrap an appropriate amount of raw tape on the water inlet and outlet pipes to enhance the airtightness between the pipes, and then use a wrench to tighten the pipe joints. Connected to the water inlet and outlet. The existing joint structure has the defect of complicated ...
