[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, a rotating plastic part includes a first connector 1 and a second connector 2 rotatably mounted together. The first connector 1 and the second connector 2 are integrally molded from plastic.

[0024] The first connector 1 includes a first connecting part 11. One end of the first connecting part 11 is integrally formed with a first threaded post 12, which facilitates the assembly of the pipe fitting with the rotating plastic part through threaded connection. A rotating hole 13 is formed on the side wall of the first connecting part 11. A fixing hole 14 coaxial with the rotating hole 13 is formed inside the first connecting part 11. The diameter of the fixing hole 14 is larger than the diameter of the rotating hole 13, which can prevent the cone 24 from falling out after installation. An installation plane is formed on the side wall of the first connecting part 11. The rotating hole 13 is formed on the installation plane. The thickness of the part of the first connecting part 11 with the installation plane is thinner, which can reduce the thickness of the plastic part after installation, and at the same time increase the contact surface between the first connector 1 and the second connector 2.

[0025] The second connector 2 includes a second connecting part 21. One end of the second connecting part 21 is integrally formed with a second threaded post 22, which facilitates the assembly of the pipe fitting with the rotating plastic part through threaded connection. A rotating shaft 23 is formed on the side wall of the second connecting part 21 to be installed in conjunction with the rotating hole 13. An installation plane is formed on the side wall of the second connecting part 21, and the rotating shaft 23 is formed on the installation plane. The thickness of the part of the second connecting part 21 with the installation plane is thinner, which can reduce the thickness of the plastic part after installation. A cone head 24 is integrally formed at the end of the rotating shaft 23 to be installed in conjunction with the fixing hole 14. The diameter of the cone head 24 is larger than the diameter of the rotating shaft 23. The cone design facilitates quick entry into the fixing hole 14 through the rotating hole 13. At least two contraction grooves 25 are formed on the cone head 24 to penetrate the cone head 24 and the rotating shaft 23, so that the cone head 24 can move towards the center and reduce its diameter to pass through the rotating hole 13 after being squeezed by external force. After the cone head 24 passes through the rotating hole 13, it will automatically spring back to complete the fixation without external force.

[0026] In this embodiment, the first threaded post 12 is a tapered post, and the large end of the first threaded post 12 is formed together with the first connecting part 11. The second threaded post 22 is a tapered post, and the large end of the second threaded post 22 is formed together with the second connecting part 21. When the pipe fitting to be connected does not have a thread, it can be fixed by direct insertion. The tapered design can meet the installation and use of pipe fittings of various diameters and is more convenient to install.

[0027] The working principle of this utility model is as follows: When in use, the cone head 24 is inserted into the fixing hole 14 through the rotating hole 13 to realize the installation of the first connecting body 1 and the second connecting body 2. Then, the two pipes are installed on the first threaded post 12 and the second threaded post 22 respectively by threaded connection or plug-in method to realize the quick combination and fixation of the two pipes.

[0028] Components not described in detail in this article are existing technologies.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
