[0002] Current polyurethane insulated pipe connection components generally connect two working steel pipes of insulated pipes, with a connecting sleeve fitted at the connection point.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 1-5This utility model discloses a polyurethane insulated pipe connection assembly, comprising: a connecting frame 1, a cover plate 9 fixedly connected to the inner surface of the connecting frame 1, a first rotating shaft 10 fixedly connected to the lower surface of the cover plate 9, a connecting rod 11 movably connected to the outer surface of the first rotating shaft 10, and a second rotating shaft 13 movably connected to the end of the connecting rod 11 away from the first rotating shaft 10. When subjected to a vertical impact force, the cover plate 9 pushes the first rotating shaft 10 downward, causing one end of the connecting rod 11 to rotate, and the other end, under the action of the second rotating shaft 13, causes a moving block 12 to move along one end of a moving plate 17. The moving block 12 is fixedly connected to the outer surface of the rotating shaft 13, and a through hole 16 is provided inside the moving block 12. A guide rod 14 is provided inside the through hole 16, and a first damping spring 15 is fixedly connected to the outer surface of the guide rod 14. The moving plate 17 is fixedly connected to the upper surfaces of the guide rod 14 and the first damping spring 15. The moving block 12 compresses the first damping spring 15, causing the first damping spring 15 to move. The elastic force of the spring 15 reacts to the moving block 12, causing it to return to its original position along the guide rod 14. A partition 23 is movably connected to the lower surface of the moving block 12. The outer surface of the moving plate 17 is fixedly connected to the partition 23. A second damping spring 22 is fixedly connected to the outer surface of the moving plate 17. A connecting plate 21 is fixedly connected to the end of the second damping spring 22 away from the moving plate 17. A sliding groove 20 is provided inside the moving plate 17. A sliding plate 19 is provided inside the sliding groove 20. The lower surface of the sliding plate 19 is fixedly connected to the connecting plate 21. A support plate 18 is fixedly connected to the upper surface of the sliding plate 19. When subjected to a horizontal upward impact force, the support plate 18 moves towards the moving plate 17. The support plate 18 pushes the sliding plate 19 to move towards the connecting plate 21 under the action of the sliding groove 20. The second damping spring 22 is stretched, and its elastic force acts on the connecting plate 21, pushing the support plate 18 connected to the sliding plate 19 back to its original position.
[0024] A fixing block 2 is fixedly connected to the outer surface of the support plate 18, and a bearing plate 5 is fixedly connected to the outer surface of the connecting frame 1. A through groove 30 is provided inside the bearing plate 5, and a T-shaped block 29 is provided inside the through groove 30. A movable shaft 24 is movably connected to the upper surface of the bearing plate 5, and a rotating plate 25 is fixedly connected to the outer surface of the movable shaft 24, allowing the rotating plate 25 to rotate flexibly on the movable shaft 24. A limiting plate 8 is fixedly connected to the outer surface of the rotating plate 25. Threaded holes 6 are provided inside the limiting plate 8, the bearing plate 5, and the fixing block 2. A fixing shaft 7 is provided inside the threaded hole 6, and the fixing shaft 7 passes into the threaded hole 6. Rotating and tightening fixes the limiting plate 8, the bearing plate 5, and the fixing block 2. A first rotating shaft 26 is movably connected to the end of the rotating plate 25 away from the movable shaft 24, and a push rod 31 is fixedly connected to the outer surface of the first rotating shaft 26. A movable plate 28 is movably connected to the outer surface of the first rotating shaft 26. A second rotating shaft 27 is movably connected to the end of the movable plate 28 furthest from the first rotating shaft 26. Pulling the push rod 31 causes the rotating plate 25 to move upwards under the action of the movable shaft 24. Under the action of the push rod 31, one end of the movable plate 28 rotates upwards along with the first rotating shaft 26 and the second rotating shaft 17, while the other end drags the T-shaped block 29, moving it along the through groove 30 and causing the fixed sleeve 3 to move. The outer surface of the second rotating shaft 27 is fixedly connected to the T-shaped block 29, and the lower surface of the T-shaped block 29 is fixedly connected to the fixed sleeve 3. A rust-proof layer 4 is fixedly connected to the inner surface of the fixed sleeve 3. The rust-proof layer 4 is made of organic coating, giving the polyurethane insulated pipe and the inner wall of the fixed sleeve 3 rust-proof properties.
[0025] Working principle: During use, position the polyurethane insulated pipe on the fixing block 2, pull the push rod 31, and the rotating plate 25 moves upward under the action of the movable shaft 24. The movable plate 28 rotates upward at one end with the first rotating shaft 26 and the second rotating shaft 17 under the action of the push rod 31, while the T-shaped block 29 at the other end moves along the through groove 30, driving the fixing sleeve 3 to move. When the rotating plate 25 is vertical, the polyurethane insulated pipe enters the fixing sleeve 3, and the fixing shaft 7 passes into the threaded hole 6. Rotating and tightening fixes the limiting plate 8, the bearing plate 5, and the fixing block 2, thus fixing the polyurethane insulated pipe in the fixing sleeve 3. When subjected to a vertical impact force, the cover plate 9 pushes the first rotating shaft 10 downward, driving the connecting rod. One end of the 11 rotates, and the other end, under the action of the second rotating shaft 13, drives the moving block 12 to move along one end of the moving plate 17. The moving block 12 compresses the first damping spring 15. The elastic force of the first damping spring 15 reacts to the moving block 12, causing the moving block 12 to return to its original position along the guide rod 14. When subjected to a horizontal upward impact force, the support plate 18 moves towards the moving plate 17. The support plate 18 pushes the sliding plate 19 to move towards the connecting plate 21 under the action of the sliding groove 20. The second damping spring 22 is stretched. The elastic force of the second damping spring 22 acts on the connecting plate 21, pushing the support plate 18 connected to the sliding plate 19 back to its original position, so that the connecting assembly can have the ability to dampen and buffer when subjected to horizontal or vertical impacts.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
