At the same time, although the existing three-way pipe fittings are provided with silicone rings, they are not adapted to the sizes of PVC pipes and silicone rings, that is, there are gaps between the PVC pipes and the silicone rings and the three-way pipe fitting body, which will also cause leakage, bringing certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a PVC three-way pipe fitting that is easy to disassemble and assemble. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a PVC three-way pipe fitting which is easy to disassemble and assemble is provided with three groups of assembled waterproof structures, which include a first silicone waterproof ring 4, a fixing ring 7, an assembly tube 2 and a sleeve 3. The assembly tube 2 is limited to the PVC tube by the sleeve 3, and the end face of the PVC tube mouth is against the first silicone waterproof ring 4 to maximize the waterproof effect. The diameters of the first inlet and outlet holes 6 and the second inlet and outlet holes 8 are the same, and the diameters of the first inlet and outlet holes 6 and the second inlet and outlet holes 8 are smaller than the diameter of the pipe fitting through hole 10. The sleeve 3 and the assembly tube 2 are threadedly connected, and the assembly tube 2 and the connecting pipe mouth 9 are threadedly connected.

[0023] like Figure 1-Figure 4 As shown, the connecting pipe 13 and the screw hole 12 are threadedly connected, the connecting pipe 13 and the vertical pipe 1 are an integrated structure, the second silicone waterproof ring 14 and the connecting pipe 13 are detachably connected, the first silicone waterproof ring 4 and the fixing ring 7 are detachably connected, and a plurality of groups of arc holes are arranged inside the assembly tube 2, and the inner diameter of the connecting pipe mouth 9 is consistent with the outer diameter of the assembly tube 2.

[0024] It should be noted that the utility model is a PVC three-way pipe fitting which is easy to disassemble and assemble. When in use, the vertical pipe 1 and the horizontal pipe 11 are assembled together through the connecting pipe 13 and the screw hole 12, and the second silicone waterproof ring 14 is squeezed through the connecting pipe 13 and the screw hole 12, so that the second silicone waterproof ring 14 is against the connection between the vertical pipe 1 and the connecting pipe 13, thereby enhancing the waterproofness between the two. At the same time, the three groups of assembly pipes 2 are spirally assembled into the connecting pipe port 9, and the sleeve 3 is installed on the PVC pipe port to be assembled.

[0025] Then insert the PVC tube into the three groups of assembly tubes 2 so that the end of the PVC tube is against the first silicone waterproof ring 4, and spirally rotate the sleeve 3 from the PVC tube to the arc-shaped hole inside the assembly tube 2 until the assembly tube 2 is tightly against the outer wall of the PVC tube and the user is difficult to rotate, thereby completing the fixation of the PVC tube. At the same time, the end of the PVC tube squeezes the first silicone waterproof ring 4 inward, and the first silicone waterproof ring 4 and the fixing ring 7 are tightly pressed together. Since the diameter of the PVC tube is larger than the diameter of the second liquid inlet and outlet hole 8, there is no gap between the end face of the PVC tube mouth and the first silicone waterproof ring 4 when the liquid is inlet and outlet. The waterproof function of the first silicone waterproof ring 4 is also enhanced by cooperating with multiple groups of rings 5.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
