[0005] In the above-mentioned water inlet pipe, the quick-connect unit is composed of a connecting pipe and a connecting sleeve. The inner end of the connecting pipe is connected to the above-mentioned pipe body. The connecting sleeve is arranged on the connecting pipe and threadedly connected to the connecting pipe. The inner circumferential wall of the connecting sleeve at the inner end is provided with a radially inwardly protruding protrusion, and a gap is left between the inner wall of the connecting sleeve and the outer wall of the connecting pipe through the protrusion.
[0006] In the above-mentioned water inlet pipe, the connecting sleeve is used to extend the outer end of the connecting sleeve out of the connecting pipe through the protrusion, and the connecting pipe is provided with an outer convex ring which protrudes radially outward and slides with the connecting sleeve on the outer peripheral wall of the outer end, and an encryption unit which enhances the sealing and prevents over-adjustment is provided between the outer convex ring and the protrusion, and the encryption unit is composed of a sealing ring gasket and a spring, and the spring and the sealing ring gasket are both sleeved on the connecting pipe, and the two ends of the spring are respectively in conflict with the sealing ring gasket and the protrusion, and the sealing ring gasket is in conflict with the outer convex ring through the spring.
[0007] In the above-mentioned water inlet pipe, the grasping unit consists of a grip sleeve and a handle, the grip sleeve is arranged on the pipe body and is threadedly connected thereto, the pipe body is provided with a limit ring protruding radially outward at the quick-connect unit end and used to limit the position of the grip sleeve, and the handle is arranged on the grip sleeve and is connected thereto.
[0008] Compared with the prior art, this water inlet pipe has the following advantages:
[0009] 1. A quick-connect unit is provided at one end of the pipe body, which is connected to the pipe body and convenient for connecting with other pipe fittings. A grasping unit is provided on the pipe body, which is connected to the pipe body and convenient for human hand grasping and can adjust the position. The above structure is convenient for its assembly and also convenient for human hand grasping. BRIEF DESCRIPTION OF THE DRAWINGS
