[0014] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.
[0015] See Figure 1-2 A CPVC cable protection pipe includes an outer pipe 1 and an inner pipe 3. The outer pipe 1 and the inner pipe 3 are both integrally constructed of CPVC material. The inner pipe 3 is fitted inside the outer pipe 1 and slidably connected to its inner wall. The outer pipe 1 is provided with a first ventilation port 2 arranged in a circular array, and the inner pipe 3 is provided with a second ventilation port 4. The inner pipe 3 serves to support the outer pipe 1. The outer wall of the outer pipe 1 can close the second ventilation port 4. When the second ventilation port 4 coincides with the first ventilation port 2, the inside of the pipe is ventilated.
[0016] See Figure 1-3One end of the outer tube 1 is fixed with an outer pull plate 5 arranged in a circular array. The inner tube 3 is fixed with an inner pull plate 6 on the same side corresponding to the outer pull plate 5. Both the inner pull plate 6 and the outer pull plate 5 extend inward. An inner groove 10 is provided on the outer side of one of the outer pull plates 5. A drive bolt 7 is provided in the inner groove 10. The inner groove 10 is used to place the nut of the drive bolt 7. The nut of the drive bolt 7 is located in the inner groove 10 and does not affect the connection of the pipe. The drive bolt 7 passes through the inner pull plate 6 opposite to it and is threadedly connected to the threaded hole 9 on it. When the drive bolt 7 rotates, it drives the inner pull plate 6 to move horizontally. Sliding columns 8 are fixed on the other outer pull plates 5. The sliding columns 8 pass through the inner pull plates 6 and are slidably connected to them to maintain the stability of the sliding. The outer tube 1 and the inner tube 3 are tightly connected. When the outer pull plate 5 and the inner pull plate 6 are in contact, the outer tube 1 is blocked at the second ventilation opening 4, so that the pipe is closed.
[0017] See Figure 1 , 3 The stud of the drive bolt 7 is provided with a side slot 11, and a stop 12 is slidably provided on the side slot 11. The stop 12 is slidably connected to the outer pull plate 5. A slide rail is provided on the side slot 11, and the stop 12 is slidably connected to the slide rail. The stop 12 is located in the side slot 11 and is provided with a spring. The stop 12 can be fully retracted into the side slot 11. Pressing the stop 12 causes it to retract into the side slot 11, so that the stud passes through the outer pull plate 5. The drive bolt 7 and the stop 12 clamp the outer pull plate 5. After passing through the hole, the stop 12 is popped out by the built-in spring, which limits the drive bolt 7.
[0018] This utility model of CPVC cable protection pipe has a simple structure. Its double-pipe structure makes it more supportive, and the pipe wall can be opened for heat dissipation in high-temperature environments. It is suitable for different installation situations, and the two pipes are easy to adjust. It is highly practical and suitable for widespread application.
[0019] For specific usage, please refer to... Figure 1-3 When installing the drive bolt 7, insert it into the built-in groove 10. During the process of its stud passing through, press the stop block 12 as it passes by to retract it into the side slot 11. After passing through the hole, the stop block 12 is popped out by the built-in spring. At this time, the nut of the drive bolt 7 and the stop block 12 clamp the outer pull plate 5, thus completing the installation of the drive bolt 7. The position of the drive bolt 7 will not move. When it rotates, it can drive the inner tube 3 to slide. In different installation environments, if a closed state is required, the inner tube 3 and the first ventilation port 2 of the outer auxiliary pipe 1 will coincide to close the pipe, and the two layers of pipes will provide better support. When ventilation is required, by rotating the drive bolt 7, the threaded hole 9 will be driven to translate, thereby driving the inner tube 3 to slide on the outer auxiliary pipe 1, coinciding the first ventilation port 2 and the second ventilation port 4, providing better heat dissipation. When the drive bolt 7 is not rotated by external force, the position of the inner tube 3 will be fixed and will not slide.
