[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Refer to Figures 1-4, A PVC electrician pipe for two-color electrical installation projects, including a PVC pipe formed by splicing a first semi-circular pipe 1 and a second semi-circular pipe 2. Reinforcing plates 13 are respectively connected to one side of the inner walls of the first semi-circular pipe 1 and the second semi-circular pipe 2. A clamping strip 3 is connected to one side of the reinforcing plate 13 on one side of the first semi-circular pipe 1, and a clamping groove 4 is connected to the surface of the reinforcing plate 13 on one side of the second semi-circular pipe 2; A fixing pipe 5 is arranged on the surface of the PVC pipe, and fixing strips 6 are annularly and equidistantly inclined on the inner wall of the fixing pipe 5. By rotating the annular plate 8, the connected pressing plate 12 is moved to the surface of the fixing strip 6 and pressed against it, causing the fixing strip 6 to undergo slight deformation and its bottom end to move away from the surface of the PVC pipe, so that the fixing pipe 5 can be removed from the surface of the PVC pipe, facilitating the removal of the clamping strip 3 from the inside of the clamping groove 4, thereby disassembling the PVC pipe for easy maintenance of the circuit inside it.

[0025] Furthermore, the distance between the bottoms of the symmetrically arranged fixing strips 6 is smaller than the diameter of the PVC pipe. This is to facilitate that after the PVC pipe is moved into the fixing pipe 5 and contacts the bottom end of the fixing strip 6 and is pressed against it, the fixing strip 6 can undergo slight deformation, the bottom end of the fixing strip 6 contacts the surface of the PVC pipe and is pressed against it, thereby enabling people to limit the position of the PVC pipe.

[0026] Furthermore, the material of the fixing strip 6 is polypropylene, and polypropylene has prominent toughness performance and can undergo plastic deformation without being easily broken when subjected to external forces.

[0027] Furthermore, the inside of the clamping strip 3 and the clamping groove 4 are in snap connection, which is to facilitate splicing the two semi-circular pipes into a PVC pipe. Identification cards are arranged inside the two semi-circular pipes to facilitate the identification of wires of different colors inside the pipe body, making it convenient for maintenance.

[0028] Furthermore, moving grooves 7 are respectively annularly and equidistantly opened on the upper and lower sides of the inner wall of the fixing pipe 5, and an annular plate 8 is threadedly connected to the upper and lower parts of the inner wall of the fixing pipe 5. A sliding groove 9 is opened on the inner wall of the annular plate 8, and a slider 10 is slidably connected inside the sliding groove 9. A connecting rod 11 that is movably connected to the inside of the moving groove 7 is connected to one side of the slider 10, and an annular pressing plate 12 for pressing the fixing strip 6 is connected to one end of the connecting rod 11. By rotating the annular plate 8, the annular plate 8 can rotate and move, so as to drive the connecting rod 11 and the pressing plate 12 to move through the slider 10 and the sliding groove 9, facilitating the movement of the pressing plate 12 to the surface of the fixing strip 6 and pressing it to make it move.

[0029] Furthermore, the pressing plate 12 contacts the upper part of the surface of the fixing strip 6, and the inner diameter of the annular pressing plate 12 is larger than the diameter of the PVC pipe. This is to facilitate pressing the fixing strip 6 by the pressing plate 12 to make the fixing strip 6 move away from the surface of the PVC pipe.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
