DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

[0030] Please refer to Figures 1-6 The present application provides a technical solution: a water supply pipe connecting structure convenient to use, comprising: a water supply pipeline, an assembly structure and a sealing structure.

[0031] Referring to Figure 1 The water supply pipeline is composed of the left water supply pipe 10 and the right water supply pipe 11.

[0032] Referring toFigures 2-3 The assembly structure includes an inner tube 20, a retaining ring 21 fixedly installed on the outer surface of the inner tube 20, an outer tube 22 fixedly installed on both ends of the retaining ring 21, and a locking assembly arranged on the surface of the outer tube 22. Both ends of the inner tube 20 are set to be conical, and the inner tube 20 allows the left water supply pipe 10 and the right water supply pipe 11 to be inserted.

[0033] See Figure 4 and Figure 6 The sealing structure is arranged on the surface of the inner tube 20 to improve the sealing between the water supply pipe and the inner tube 20. The sealing structure includes a first sealing ring 40 and a second sealing ring 41 fixedly installed at one end of the first sealing ring 40. The first sealing ring 40 is located between the inner tube 20 and the water supply pipe, and the second sealing ring 41 is located on one side of the retaining ring 21. The end of the first sealing ring 40 away from the second sealing ring 41 is set to be conical.

[0034] The two first sealing rings 40 are respectively put into the inner tube 20. At this time, the second sealing ring 41 will contact one end of the retaining ring 21. When the left water supply pipe 10 and the right water supply pipe 11 are inserted between the inner tube 20 and the outer tube 22, at this time, one of the first sealing rings 40 will be between the left water supply pipe 10 and the inner tube 20, and the other first sealing ring 40 will be between the right water supply pipe 11 and the inner tube 20. In addition, one end of the left water supply pipe 10 and the right water supply pipe 11 will contact the second sealing ring 41, forming a sealing surface again, thereby improving the sealing between the water supply pipe and the inner tube 20.

[0035] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The locking assembly includes a locking cap 30, a first conical groove 31 formed on the surface of the outer tube 22, a rubber clamping ring 32 slidably mounted on the inner wall of the first conical groove 31, and a second conical groove 33 formed on the outer surface of the rubber clamping ring 32. The inner wall of the locking cap 30 is provided with an internal thread, and the surface of the outer tube 22 is provided with an external thread that matches the internal thread. The end of the locking cap 30 close to the rubber clamping ring 32 is rotatably connected to a connecting ring 34.

[0036] Insert the left water supply pipe 10 and the right water supply pipe 11 into the outer tube 22 respectively. At this time, the left water supply pipe 10 and the right water supply pipe 11 will be between the inner tube 20 and the outer tube 22. Then put the rubber clamping ring 32 into the first conical groove 31, and then tighten the locking cap 30. At this time, the connecting ring 34 will be close to the rubber clamping ring 32, and the second conical groove 33 will be close to the first conical groove 31, and squeeze the rubber clamping ring 32, so that the two squeezed and deformed rubber clamping rings 32 can contact the left water supply pipe 10 and the right water supply pipe 11 respectively, so that the left water supply pipe 10 and the right water supply pipe 11 can be fixed between the outer tube 22 and the inner tube 20 respectively.

[0037] Compared with the prior art, the device can clamp the left water supply pipe 10 and the right water supply pipe 11 between the inner pipe 20 and the outer pipe 22 by means of the assembly structure, so that the left water supply pipe 10 and the right water supply pipe 11 can still be inserted between the inner pipe 20 and the outer pipe 22 after the left water supply pipe 10 and the right water supply pipe 11 are cut, thereby avoiding the problem that the left water supply pipe 10 and the right water supply pipe 11 cannot be connected after being cut.

[0038] The above merely describes a preferred specific implementation of the present application, but the scope of protection of the present application is not limited thereto, and any person skilled in the art should be covered within the scope of protection of the present application according to the technical scheme and concept of the present application, which is equivalent to replacement or change.
