[0025] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.
[0026] To address the problems existing in the background art, this application proposes the following technical solution: a PPH plastic pipe for a modular splicing support assembly.
[0027] The specific technical solution includes several fixed tubes 1, each with an extension tube 2 at both ends. A connecting mechanism 3 is provided between one end of two adjacent extension tubes 2. The connecting mechanism 3 includes a fixed ring 12, a plug-in ring 15, and a plug-in rod 16. The fixed ring 12 is fixedly installed at one end of one extension tube 2, and the plug-in ring 15 is fixedly installed at one end of the other extension tube 2. The fixed ring 12 and the plug-in ring 15 correspond to each other. A plug-in groove 13 is provided on one side of the fixed ring 12, and a snap-fit groove 14 is provided on one side of the inner wall of the plug-in groove 13. The plug-in rod 16 is fixedly installed on one side of the plug-in ring 15 and is movably inserted into the plug-in groove 13. A snap-fit block 17 is fixedly installed on one side of the plug-in rod 16. 7. The movable latch is connected in the latching groove 14. There are two plug rods 16 and two latching blocks 17, and the two plug rods 16 are set accordingly. The number of plug grooves 13 and latching grooves 14 are respectively corresponding to the number of plug rods 16 and latching blocks 17. A sliding ring 18 is provided on one side of the plug ring 15. The sliding ring 18 is sleeved on the periphery of one end of the extension tube 2. An installation groove 19 is opened on one side of the plug ring 15. Two latching rods 20 are fixedly installed on one side of the sliding ring 18. The latching rods 20 are inserted into the installation groove 19. Several latching slots are opened on one side of the fixed ring 12. One end of the latching rod 20 is inserted into the latching slot. Two mounting slots are opened on one side of the plug ring 15. A spring 21 is provided between the sliding ring 18 and one side of the inner wall of the mounting slot.
[0028] Reference Figure 2 and Figure 3As shown, both sides of the inner wall of the fixed tube 1 are provided with limiting grooves 5, and both sides of one end of the extension tube 2 are fixedly installed with limiting sliders 6. The limiting sliders 6 are slidably installed in the limiting grooves 5. Both ends of the fixed tube 1 are provided with fixing mechanisms 4. The fixing mechanism 4 includes a mounting ring 7, a threaded cylinder 8, a threaded rod 9 and a limiting pressure plate 11. The mounting ring 7 is fixedly installed at one end of the fixed tube 1 and is sleeved around the periphery of the extension tube 2.

One end of the threaded rod 9 is rotatably connected to one side of the limiting pressure plate 11. By rotating the threaded rod 9, the threaded rod 9 moves upward along the threaded cylinder 8, causing the threaded rod 9 to drive the limiting pressure plate 11 to retract towards the guide groove 10, thereby releasing the fixation of the extension tube 2. Then, by pulling the extension tube 2, the extension tube 2 extends outward, allowing the operator to adjust the overall length of the plastic tube according to actual needs. After adjustment, by rotating the threaded rod 9 in the opposite direction, the threaded rod 9 moves downward along the threaded cylinder 8. The downward movement of the threaded rod 9 can drive the limiting pressure plate 11 to move downward, causing the limiting pressure plate 11 to squeeze the extension tube 2, thereby fixing and limiting the extension tube 2. The contact surface between the limiting pressure plate 11 and the extension tube 2 is made of rubber.
[0029] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:
[0030] In use, when connecting two PPH plastic tubes, align the insertion ring 15 at one end of one plastic tube with the fixing ring 12 at the other end. Then, pull the sliding ring 18, causing it to retract the locking rod 20 into the mounting groove 19. Next, the insertion rod 16 on one side of the insertion ring 15 drives the locking block 17 into the insertion groove 13 on one side of the fixing ring 12. Then, rotate one of the plastic tubes, causing the insertion rod 16 to screw the locking block 17 into the locking groove 14. The locking block 17 engages with the locking groove 14, thus connecting the insertion ring 15 and the fixing ring 12. 2. Fixed connection, which allows the two plastic tubes to be connected, improving the convenience for workers when connecting the two plastic tubes. Then, by loosening the sliding ring 18, the spring 21 drives the sliding ring 18 to move towards the insertion ring 15 through its own elasticity. The movement of the sliding ring 18 can drive the locking rod 20 to move, so that the locking rod 20 extends out of the mounting groove 19 and inserts into the locking groove on one side of the fixed ring 12, thereby preventing the insertion ring 15 and the fixed ring 12 from rotating, ensuring that the locking block 17 can be stably locked in the locking groove 14, improving the stability of the connection between the insertion ring 15 and the fixed ring 12.
