DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1-9 As shown, an anti-bending electric plastic-coated steel pipe comprises: an electric plastic-coated steel pipe 1, an anti-bending sleeve 2 and a guide rod 10.

[0032] There are several groups of electric plastic-coated steel pipes 1, and the several electric plastic-coated steel pipes 1 are welded to each other. The side ends of one group of electric plastic-coated steel pipes 1 are matched and connected with the mounting plate 8, and the upper and lower ends of the other group of electric plastic-coated steel pipes 1 away from the mounting plate 8 are fixedly connected with the base 3 and the top seat 4 respectively. When multiple groups of electric plastic-coated steel pipes 1 are in use, the multiple groups of electric plastic-coated steel pipes 1 are sequentially abutted and then fixed together by welding;

[0033] The anti-bending sleeve 2 is provided with several groups and is sleeved and connected to the outer wall of the electric plastic-coated steel pipe 1. The top of the anti-bending sleeve 2 is cooperated with a threaded rod 5. The threaded rod 5 is located at the top of the electric plastic-coated steel pipe 1 and the side end is cooperated with the top seat 4. The guide rod 10 is cooperated with the bottom of the anti-bending sleeve 2. The side end of the guide rod 10 is fixedly connected to the base 3. In order to avoid bending when multiple groups of electric plastic-coated steel pipes 1 are welded together, multiple groups of anti-bending sleeves 2 are sleeved on the electric plastic-coated steel pipe 1 in turn, and then the anti-bending sleeves 2 are moved. Several groups of anti-bending sleeves 2 are equidistantly arranged on the electric plastic-coated steel pipe 1, wherein the welding points of multiple groups of electric plastic-coated steel pipes 1 are sleeved with the anti-bending sleeve 2, and the anti-bending sleeve 2 is supported by the outer wall of the electric plastic-coated steel pipe 1 to avoid bending. In order to prevent the electric plastic-coated steel pipe 1 from bending, in order to facilitate the installation of the anti-bending sleeve 2, when several anti-bending sleeves 2 are mounted on the electric plastic-coated steel pipe 1, the mounting plate 8 is installed on the side end of the electric plastic-coated steel pipe 1, and the threaded rod 5 rotates. The threaded rod 5 drives the anti-bending sleeve 2 to move once by being threadedly connected to the top of the anti-bending sleeve 2. When the threaded rod 5 stops rotating, the threaded rod 5 and the top of the anti-bending sleeve 2 are threadedly connected to limit and fix the anti-bending sleeve 2. When the anti-bending sleeve 2 slides along the outer wall of the electric plastic-coated steel pipe 1, the bottom of the anti-bending sleeve 2 slides along the guide rod 10. The guide rod 10 and the threaded rod 5 can cooperate to limit the anti-bending sleeve 2 to avoid the anti-bending sleeve 2 from rotating and tilting during the movement.

[0034] In some specific embodiments, the anti-bending sleeve 2 is slidably connected to the outer wall of the electric plastic-coated steel pipe 1, a threaded hole 18 is opened at the top of the anti-bending sleeve 2, and a sliding hole 19 is opened at the bottom of the anti-bending sleeve 2. The inner wall of the threaded hole 18 is threadedly connected to the threaded rod 5, and the inner wall of the sliding hole 19 is slidably connected to the guide rod 10. When the anti-bending sleeve 2 moves, the threaded rod 5 rotates, and the threaded rod 5 drives the anti-bending sleeve 2 to move through the threaded connection with the threaded hole 18. At the same time, the sliding hole 19 opened at the bottom of the anti-bending sleeve 2 slides along the guide rod 10, and the inner wall of the sliding hole 19 and the guide rod 10 abut to provide limiting support for the anti-bending sleeve 2.

[0035] In some specific embodiments, a bearing surface 6 is provided on the outer wall of one end of the threaded rod 5 close to the mounting plate 8, and the side end of the threaded rod 5 is cooperated with the servo motor 7, and the bearing surface 6 cooperates with the anti-bending sleeve 2. A rotating groove 17 is provided on the side end of the top seat 4, and a rotating seat 16 is clamped and connected in the rotating groove 17 and rotatably connected to the rotating seat 16. The rotating seat 16 is fixedly connected to the side end of the threaded rod 5, and the side end of the servo motor 7 is fixedly connected to the connecting rod 11, and the side end of the connecting rod 11 is fixedly connected to the cross seat 13. A cross slot 14 is provided on the end of the threaded rod 5 away from the rotating seat 16, and the inner wall of the cross slot 14 is abutted against the cross seat 13. In order to facilitate the rotation of the threaded rod 5, the staff holds the servo motor 7 and inserts the cross seat 13 into the cross slot 14. When the servo motor 7 is running, the servo motor 7 drives the cross seat 13 to rotate through the connecting rod 11, and the cross seat 13 drives the threaded rod by abutting against the inner wall of the cross slot 14. 5 rotates. In order to facilitate the sequential movement of the anti-bending sleeves 2, the anti-bending sleeves 2 are placed on the bearing surface 6. The surface of the bearing surface 6 does not have a threaded line. When the threaded rod 5 rotates, the anti-bending sleeves 2 on the bearing surface 6 will not be threadedly connected. Therefore, the anti-bending sleeves 2 at the bearing surface 6 will not move automatically. When the threaded rod 5 stops rotating, the staff holds the servo motor 7 to pull the cross seat 13 out of the cross slot 14, so as to facilitate the servo motor 7 to be used multiple times. It should be noted that when the threaded rod 5 rotates, the threaded rod 5 drives the rotating seat 16 to rotate in the rotating groove 17. The rotating seat 16 is connected to the inner wall of the rotating groove 17 to provide a limiting support for the threaded rod 5. The threaded rod 5 rotates along the inner wall of the rotating hole 15. The rotating hole 15 provides support for the rotation of the threaded rod 5, thereby ensuring that the two ends of the threaded rod 5 are stable when the threaded rod 5 rotates.

[0036] In some specific embodiments, a rotating hole 15 is provided on the top of the mounting plate 8, a positioning hole 20 is provided on the side end of the bottom of the mounting plate 8, and fixing holes 12 are provided at both ends of the mounting plate 8 through the inside of the electric plastic-coated steel pipe 1. The rotating hole 15 cooperates with the threaded rod 5, and the positioning hole 20 cooperates with the guide rod 10. The inner wall of the fixing hole 12 is threadedly connected with a fixing bolt 9, and the fixing bolt 9 is abutted against the side end of the mounting plate 8. When several anti-bending sleeves 2 are placed on the electric plastic-coated steel pipe 1, the mounting plate 8 is installed on the side end of the electric plastic-coated steel pipe 1, and the fixing bolt 9 is rotated. The fixing bolt 9 fixes the mounting plate 8 on the anti-bending sleeve 2 through the threaded connection with the fixing hole 12. When the mounting plate 8 is installed on the side end of the electric plastic-coated steel pipe 1, the guide rod 10 is inserted into the positioning hole 20, and the inner wall of the positioning hole 20 abuts against the guide rod 10, thereby providing limited support for the two ends of the guide rod 10, further ensuring the stability of the anti-bending sleeve 2 moving along the guide rod 10.

[0037] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
