[0002] Porous PE communication pipe, also known as plum blossom pipe or honeycomb pipe, is made of HDPE (high-density polyethylene) as the main raw material, with an integrated porous structure, and processed by composite co-extrusion molding. It has strong compatibility and practicality, suitable for the laying of cables, optical cables, coaxial cables, PCM cables and many other cables, and is widely used in telecommunications, radio and television, railways, troops, colleges and universities, large and medium-sized industrial and mining enterprises and other fields.

[0003] Announcement No. CN 219779716 U discloses a porous PE communication pipe structure, which relates to the technical field of PE pipe fittings, including an outer pipe, one end of which is provided with a groove, and the other end is fixedly connected with a fixed block, the fixed block is plugged into the groove, and also includes: a locking mechanism, which includes two locking blocks, the fixed block is provided with a slide groove adapted to the two locking blocks, the two locking blocks are respectively slidably connected in the two slide grooves, each locking block is respectively provided with a spring between the inner wall of the slide groove where it is located, the two side walls of the slide groove are connected with a locking groove, and the two locking blocks are respectively plugged into the two locking grooves. The fixed block of a PE communication pipe is plugged into the groove of another PE communication pipe, and the two PE communication pipes can be automatically connected by the locking mechanism through only one plugging action. When disassembling, the two PE communication pipes can be separated by squeezing the locking block, which can be quickly connected, improves the connection efficiency, and facilitates maintenance work.

[0022] Please refer to 1-4, a porous PE communication pipe, including: a front pipe 1, an inner liner pipe 12 is fixedly connected to the end of the front pipe 1, a receiving groove 22 is opened in the rear pipe 2, a waterproof filling ring 4 is connected to the outer shell of the inner liner pipe 12, a sealing ring 3 is abutted at the connecting position of the front pipe 1 and the rear pipe 2, a second supporting pipe 6 is arranged in the middle position of the front pipe 1, a first supporting pipe 5 is arranged in the middle position of the rear pipe 2, a connecting block 11 is threadedly connected to the second supporting pipe 6, and a wedge block 21 is threadedly connected to the first supporting pipe 5. When the wedge block 21 is inserted into the connecting block 11, the front pipe 1 and the rear pipe 2 will be locked together.

[0023] Specifically, the thread groove opened in one end of the connecting block 11 is threadedly connected to the second support tube 6, one end of the wedge block 21 is a wedge, and the other end is threadedly connected to the first support tube 5. The front tube 1 and the rear tube 2 are essentially the same structure. Figure 1The left side of the second support tube 6 is set in the front tube 1 and is indented into the front tube 1 for a distance, and the wedge block 21 is threadedly connected thereon. Similarly, the right side of the first support tube 5 is threadedly connected to the connecting block 11 in the rear tube 2, and the left side of the first support tube 5 is indented into the rear tube 2 for a distance and is threadedly connected to the wedge block 21. When the front tube 1 is inserted into the rear tube 2, the inner liner tube 12 presses the sealing ring 3 against the rear tube 2. At the same time, the wedge block 21 is inserted into the transverse groove 111 to complete the locking of the front tube 1 and the rear tube 2. The locking mechanism includes a connecting block 11, a screw 13, a slider 131, a spring 132, and a wedge block 21. The locking of the front tube 1 and the rear tube 2 is completed by the transverse groove 111 and the vertical groove 112 opened on the connecting block 11.

[0024] The utility model increases the strength of the communication pipe by arranging a first supporting tube 5 inside the front pipe 1 and the rear pipe 2, and arranging a sealing ring 3 and a waterproof filling ring 4 between the front pipe 1 and the rear pipe 2 to enhance its waterproof capability, thereby avoiding the erosion of the wires by sewage accumulation in the communication pipe. Meanwhile, the locking mechanism between the front pipe 1 and the rear pipe 2 is arranged inside the front pipe 1 and the rear pipe 2, thereby avoiding the erosion of the locking mechanism and shortening its service life, thereby making the communication pipe more solid, having a better protective effect and a longer service life.

[0025] Furthermore, a screw 13 is threadedly connected to the connecting block 11, a slider 131 is slidably arranged inside the screw 13, and the slider 131 is connected to the screw 13 via a spring 132, one end of the spring 132 is fixedly connected to the inner cavity wall of the screw 13, and the other end of the spring 132 is fixedly connected to the top of the slider 131.

[0026] Furthermore, a transverse groove 111 and a vertical groove 112 are provided in the connecting block 11 . The transverse groove 111 is connected to the vertical groove 112 . The screw 13 is threadedly connected in the vertical groove 112 . When the wedge block 21 is inserted into the vertical groove 112 from the transverse groove 111 , it is locked in the connecting block 11 by the slider 131 .

[0027] Specifically, refer to Figures 1 to 4 When the front tube 1 is inserted into the rear tube 2, the inner lining tube 12 presses the sealing ring 3 against the rear tube 2. At the same time, the wedge block 21 is inserted into the transverse groove 111, and the wedge block 21 squeezes the slider 131, thereby overcoming the elastic force of the spring 132 and making the slider 131 slide upward in the vertical groove 112. When the end of the wedge block 21 reaches the bottom of the transverse groove 111, the elastic force of the spring 132 drives the slider 131 to lock the end of the wedge block 21 in the connecting block 11, thereby completing the locking of the front tube 1 and the rear tube 2.

[0028] In a solution further provided by the present invention, the waterproof filling ring 4 is a water-blocking tape ring.

[0029] Specifically, refer to Figure 1By setting a water-blocking tape ring, moisture can be prevented from penetrating longitudinally along the inner lining pipe 12, while the sealing ring 3 prevents moisture from entering between the front pipe 1 and the rear pipe 2, thereby achieving the purpose of preventing moisture from entering the communication pipe in a humid environment or underwater environment.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
