DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4As shown, the utility model provides a technical solution: a PP-R antibacterial nano-insulated pipe, comprising an antibacterial nano-tube 1, a first connector 11 is fixedly connected to one side of the antibacterial nano-tube 1, and the first connector 11 is fixedly connected to an end away from the antibacterial nano-tube 1 to facilitate the rapid installation of two groups of connecting pipes, a pipe 12 is fixedly connected to the side of the meshing component away from the first connector 11, and a sealing component for enhancing the sealing effect of the two groups of connecting pipes is fixedly connected to the inner side of the end of the pipe 12 close to the meshing component, and an elastic component is fixedly connected to the outer side of the meshing component. One end of the elastic component is rotatably connected to a locking component. When the antibacterial nanotube 1 is connected to the pipe 12, the antibacterial nanotube 1 and the pipe 12 are first engaged through the meshing component, and at the same time, the pipe 12 drives the sealing component to be inserted into the meshing component for sealing. Then, the elastic component is turned to drive the locking component to rotate, and then the locking component is pulled to be inserted into the first connecting member 11 for locking. This effectively improves the stability of the antibacterial nanotube 1 and the pipe 12 after installation, avoids loosening due to internal water flow impact, and thus reduces leakage.

[0022] like Figure 1 and Figure 2 As shown, the outer side of the antibacterial nanotube 1 is connected to a protective component for preventing the antibacterial nanotube 1 from being scratched, and the protective component includes a protective shell 6 which is sleeved on the outer side of the antibacterial nanotube 1, and the side of the protective shell 6 close to the first connecting member 11 is fixedly connected to the first connecting member 11, and an air hole 61 is fixedly connected to the outer side of the protective shell 6. The antibacterial nanotube 1 is protected on the outer side by the protective shell 6 during transportation and use, and the air hole 61 is used to dissipate heat, thereby effectively improving the protective effect, thereby avoiding damage to the antibacterial nanotube 1 caused by scratches, which in turn affects subsequent use.

[0023] like Figure 4 As shown, the engaging assembly includes an internal threaded barrel 2 fixedly connected to the side of the pipe 12 close to the first connecting member 11, and an external threaded barrel 21 is inserted and engaged with the inner side of the internal threaded barrel 2, and the side of the external threaded barrel 21 close to the first connecting member 11 is fixedly connected to the first connecting member 11, and the internal threaded barrel 2 is sleeved on the outside of the external threaded barrel 21. Twisting the pipe 12 drives the internal threaded barrel 2 to rotate and engage with the external threaded barrel 21, so as to engage and fix the antibacterial nanotube 1 and the pipe 12.

[0024] like Figure 4 As shown, the sealing assembly includes an insert tube 3 fixedly connected to the inner side of one end of the pipe 12 close to the internal threaded barrel 2, and the end of the insert tube 3 away from the pipe 12 is inserted into the inner side of the external threaded barrel 21, a sealing gasket 31 is fixedly connected to the outer side of the insert tube 3, and the outer side of the sealing gasket 31 fits the inner side of the external threaded barrel 21, the pipe 12 drives the insert tube 3 and the sealing gasket 31 to be inserted into the external threaded barrel 21, and the connection between the pipe 12 and the external threaded barrel 21 is sealed by the sealing gasket 31.

[0025] like Figure 3 and Figure 4 As shown, the elastic component includes a second connecting member 4 fixedly connected to the outside of the internal threaded tube 2, and the side of the second connecting member 4 close to the first connecting member 11 is in contact with the first connecting member 11, a transfer plate 41 is inserted on the inner side of the outer end of the second connecting member 4, and a plug rod 42 is inserted inside the rotating plate 41, and a return spring 43 is fixedly connected to the side of the plug rod 42 away from the first connecting member 11, and the end of the return spring 43 away from the plug rod 42 is fixedly connected to the rotating plate 41, the rotating plate 41 is rotated, and the clamping plate 5 is pulled at the same time to drive the plug rod 42 to move, so that the plug rod 42 stretches the return spring 43, and then the clamping plate 5 is rotated and clamped inside the first connecting member 11 to release it, and under the elastic potential energy of the return spring 43, the plug rod 42 and the clamping plate 5 are pulled to be inserted into the first connecting member 11 to restrict the pipeline 12, so as to drive the locking assembly to rotate.

[0026] like Figure 3 and Figure 4 As shown, the locking assembly includes a clamping plate 5 which is rotatably connected to the side of the insertion rod 42 away from the reset spring 43, and a push plate 51 is fixedly connected to the outer side of the middle end of the clamping plate 5. The rotating plate 41 is rotated and the clamping plate 5 is pulled at the same time to drive the insertion rod 42 to move, so that the insertion rod 42 stretches the reset spring 43, and then the clamping plate 5 is rotated and clamped inside the first connecting member 11 and released. Under the elastic potential energy of the reset spring 43, the insertion rod 42 and the clamping plate 5 are pulled and inserted into the first connecting member 11 to restrict the pipeline 12, so as to cooperate with the elastic force component to limit the positioning of the first connecting member 11 and the second connecting member 4.

[0027] Working principle: When installing the antibacterial nanotube 1 and the pipe 12, firstly, the pipe 12 drives the insert 3 and the sealing gasket 31 to be inserted into the external threaded tube 21, and at the same time, the internal threaded tube 2 is sleeved on the outside of the external threaded tube 21, and the pipe 12 is twisted to drive the internal threaded tube 2 to rotate and engage with the external threaded tube 21. After the internal threaded tube 2 and the external threaded tube 21 are engaged and fixed, the rotating plate 41 is toggled to rotate, and at the same time, the card plate 5 is pulled to drive the insert rod 42 to move, so that the insert rod 42 stretches the reset spring 43, and then the card plate 5 is rotated and clamped inside the first connecting member 11 to release it, and under the elastic force of the reset spring 43, the card plate 5 is rotated and clamped inside the first connecting member 11 to release it. The insertion rod 42 and the card plate 5 can be pulled down and inserted into the first connecting piece 11 to restrict the pipe 12. During subsequent disassembly, the push plate 51 is pushed to drive the card plate 5 and the insertion rod 42 to stretch the reset spring 43, and then the card plate 5 is rotated to push the rotating plate 41 back to its original position, and then the pipe 12 is twisted to drive the internal threaded tube 2 to separate from the external threaded tube 21. At the same time, the pipe 12 pulls the insertion tube 3 and the sealing gasket 31 out of the external threaded tube 21. During the transportation and use of the antibacterial nanotube 1, the protective shell 6 is used to protect the outside of the antibacterial nanotube 1, and the air vent 61 is used to dissipate heat.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
