Specific implementation manners
[0018] 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-5, An embodiment provided by the present utility model: A plastic pipe docking device, including a plastic pipe 1, a connection position 2, and an interface docking and fastening device 3. The interface docking and fastening device 3 is arranged at the connection position 2. The connection position 2 is wrapped with waterproof tape. The interface docking and fastening device 3 is movably buckled on the outer surface of the plastic pipe 1. A first arc-shaped side plate 4 is fixedly installed inside the interface docking and fastening device 3. One end of the first arc-shaped side plate 4 is movably connected to a second arc-shaped side plate 5. One end center of the first arc-shaped side plate 4 is slidably connected to an extrusion device 6. One end of the first arc-shaped side plate 4 is fixedly connected to a positioning shaft 10. A first threaded hole 8 is opened on the other end face of the first arc-shaped side plate 4. Observation slots 7 are opened at the centers of the side edges of one end faces of the first arc-shaped side plate 4 and the second arc-shaped side plate 5. Limiting sliding slots 9 are opened on both sides of the edge of one end of the first arc-shaped side plate 4 where the observation slot 7 is located. A bushing 14 is fixedly connected to one end of the second arc-shaped side plate 5. A first fastening screw 13 is spirally connected to the side edge of the other end of the second arc-shaped side plate 5. A groove 16 is opened on the center plane of the side end of the extrusion device 6. Limiting rods 15 are fixedly connected to the side edges of both ends of the extrusion device 6. A limiting hole 19 is opened at the center of the side edge of the extrusion device 6. A second fastening screw 17 is movably clamped inside the limiting hole 19. One end of the second fastening screw 17 is welded with a limiting buckle plate 18. Clamping slots 12 are opened at the centers of the sides of the first arc-shaped side plate 4 and the second arc-shaped side plate 5. One end of the first arc-shaped side plate 4 is movably buckled with the bushing 14 at one end of the second arc-shaped side plate 5 through the positioning shaft 10, so that the first arc-shaped side plate 4 and the second arc-shaped side plate 5 can be adjusted and unfolded, facilitating clamping with the outer surface of the plastic pipe 1. The first fastening screw 13 spirally penetrates through the side of the second arc-shaped side plate 5 and is spirally connected to the second threaded hole 11 on the side of the first arc-shaped side plate 4, and can fix the other ends of the first arc-shaped side plate 4 and the second arc-shaped side plate 5 after the first arc-shaped side plate 4 and the second arc-shaped side plate 5 are clamped on the outer surface of the plastic pipe 1. The center of the side end of the extrusion device 6 is slidably clamped with the side of the first arc-shaped side plate 4 through the observation slot 7, so that the extrusion device 6 can slide between the side surfaces of one ends of the first arc-shaped side plate 4 and the second arc-shaped side plate 5 and approach the outer surface of the plastic pipe 1, and squeeze and fix the upper and lower ends of the connection position 2. The limiting rods 15 are movably inserted into the side of the first arc-shaped side plate 4 through the limiting sliding slots 9, so as to prevent the extrusion device 6 from deviating during sliding, resulting in inconvenience in rotating the second fastening screw 17 to adjust the position of the extrusion device 6. The second fastening screw 17 is spirally connected to the end face of one end of the first arc-shaped side plate 4 through the first threaded hole 8, and one end of the second fastening screw 17 is movably buckled with the limiting hole 19 on the side of the extrusion device 6 through the limiting buckle plate 18. Therefore, when the second fastening screw 17 rotates, it will push the extrusion device 6 to slide horizontally through the limiting buckle plate 18 at one end. A rubber pad is fixedly connected to the side of the extrusion device 6, which can prevent the side of the extrusion device 6 from squeezing the outer surface of the connection position 2 too much and damaging the outer surface of the connection position 2.
[0020] The first arc-shaped side plate 4 is movably buckled with the bushing 14 at one end of the second arc-shaped side plate 5 through the positioning shaft 10 at one end. The first fastening screw 13 spirally penetrates through the side surface of the second arc-shaped side plate 5 and is spirally connected with the second threaded hole 11 on the side surface of the first arc-shaped side plate 4. The center of the side end of the extrusion device 6 is slidably clamped with the side surface of the first arc-shaped side plate 4 through the observation groove 7. The limiting rod 15 is movably inserted into the side surface of the first arc-shaped side plate 4 through the limiting chute 9. The second fastening screw 17 is spirally connected with the end surface of one end of the first arc-shaped side plate 4 through the first threaded hole 8, and one end of the second fastening screw 17 is movably buckled with the limiting hole 19 on the side surface of the extrusion device 6 through the limiting buckle plate 18. A rubber pad is fixedly connected to the side surface of the extrusion device 6.
[0021] Working principle: At the connection position 2 of the plastic pipe 1, first use waterproof tape to simply wrap the splicing part, and then rotate the first arc-shaped side plate 4 and one end of the second arc-shaped side plate 5 around the positioning shaft 10, so that the other ends of the first arc-shaped side plate 4 and the second arc-shaped side plate 5 are separated and unfolded. Then move the unfolded first arc-shaped side plate 4 and second arc-shaped side plate 5 close to the outer surface of the plastic pipe 1, so that the plastic pipe 1 is located inside the clamping grooves 12 on the side surfaces of the first arc-shaped side plate 4 and the second arc-shaped side plate 5 until the side surfaces of the first arc-shaped side plate 4 and the second arc-shaped side plate 5 are completely attached to the plastic pipe 1. At the same time, adjust the height positions of the first arc-shaped side plate 4 and the second arc-shaped side plate 5 on the outer surface of the plastic pipe 1, and observe that the groove 16 at the side end of the extrusion device 6 is aligned and inserted with the connection position 2, so that the connection position 2 is located at the center of the groove 16. Then rotate the second fastening screw 17 inside the first threaded hole 8, drive the limiting buckle plate 18 at one end to rotate inside the limiting hole 19, and push the extrusion device 6 to slide on the side surface of the first arc-shaped side plate 4, so that the rubber pad on the side surface of the extrusion device 6 approaches the outer surface of the plastic pipe 1 until the rubber pad on the side surface of the extrusion device 6 presses the upper and lower ends of the connection position 2, so that the connection position 2 is tightly attached to the outer surface of the plastic pipe 1. When the extrusion device 6 slides, the limiting rod 15 at the side end will slide inside the limiting chute 9. Then rotate the first fastening screw 13 to be spirally and tightly connected with the second threaded hole 11 on the side surface of the first arc-shaped side plate 4. At the same time, the side edge of one end of the second arc-shaped side plate 5 will abut against the side end surface of the extrusion device 6, thereby stably docking and fixing the connection between the plastic pipe 1 and the connection position 2 and ensuring the stability of the connection position 2.

The scope of the present invention is defined by the appended claims and their equivalents.
