Description

Technical Field

[0001] This utility model belongs to the technical field of dual-interface conduit, and specifically relates to a communication-specific open-cut flame-retardant PPGFR high-strength waterproof and permeable dual-interface conduit. Background Technology

[0002] This communication-specific open-cut, flame-retardant, high-strength, waterproof, and permeable double-joint conduit is designed specifically for communication engineering. It boasts excellent flame-retardant properties, ensuring safe use in complex environments, such as those with both high and low voltage electrical connections. Made of glass fiber reinforced polypropylene, it not only offers high strength but also superior waterproofing, effectively preventing moisture penetration and protecting internal cables. The double-joint design facilitates easy installation and improves construction efficiency. Furthermore, its corrosion resistance, high-temperature resistance, and high-pressure resistance make it an ideal choice for communication lines traversing complex terrain.

[0003] However, the existing dual-port conduit has some shortcomings. Because there are two ports on the conduit, there is no good limiting structure between the two conduits. This causes the two conduits to shake back and forth when they are hit. This reduces the installation stability of the dual-port conduit and also reduces the safety of its later use, making it very inconvenient. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a communication-specific open-cut flame-retardant PPGFR high-strength waterproof and seepage-proof double-interface conduit to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: This is a communication-specific, open-cut, flame-retardant, high-strength, waterproof, and permeable double-interface conduit, comprising a first conduit and a second conduit. The second conduit is installed inside the first conduit, and a support block is threaded to the outside of the first conduit. A sealing block is fixedly connected to the outside of the second conduit, and a first limiting block is fixedly connected to the outside of the sealing block. A second limiting block is threaded to the top of the support block.

A slot is formed at the top of the movable plate, and a matching locking block is fixedly connected to the bottom of the pressing plate, engaging inside the slot.

[0006] As a preferred technical solution, a fixing block is fixedly connected to the other side of the second limiting block. The bottom end of the fixing block is in contact with the top end of the support block. A second screw hole is opened at the top end of the fixing block. A second bolt is threadedly connected to the inner side of the second screw hole. The bottom end of the second bolt is in contact with the top end of the support block. The second limiting block is threadedly connected to the top end of the support block through the fixing block, the second screw hole, and the second bolt.

[0007] As a preferred technical solution, a groove is provided at the top of the support block, and a rubber pad is fixedly connected to the inner side of the groove. The rubber pad covers the inner side of the groove, and the position of the top of the rubber pad is symmetrical to the position of the bottom of the second bolt.

[0008] As a preferred technical solution, the top of the support block is provided with a groove that matches the second limiting block, and the bottom of the second limiting block is slidably connected to the inner side of the groove.

[0009] As a preferred technical solution, a sealing ring is fixedly connected to the top end of the first conduit, the sealing ring covers the top end of the first conduit, and the position of the sealing block corresponds to the position of the first conduit.

The support block is threaded to the outside of the first conduit through the first bolt and the first screw hole.

[0012] In summary, the present invention has the following main advantages: Firstly, during use, the first and second conduits facilitate the installation of wires and cables. Due to the presence of the first and second limiting blocks, the sleeve plate and movable plate between them can effectively limit the distance between the first and second conduits. At the same time, the user can also adjust the distance between the first and second conduits as needed. After the distance is adjusted, the user only needs to press the pressing plate with the telescopic rod to insert the locking block into the corresponding slot to prevent the movable plate from freely extending and retracting. This also effectively limits the distance between the first and second limiting blocks, thereby effectively improving the stability between the first and second conduits. Secondly, to improve the waterproofing capabilities of the first and second conduits, the user can pull the second limiting block backward through the sliding groove, which facilitates the embedding of the second conduit into the inside of the first conduit. At the same time, the sealing block will also fit against the top of the first conduit, and its sealing ring can effectively seal the connection point between the sealing block and the first conduit. The sealing gasket on the inner wall of the first conduit can fit tightly against the outer wall of the second conduit, and its waterproof sleeve can fit tightly against the wires and cables installed inside the second conduit, thereby achieving a good sealing and waterproofing effect and effectively preventing water or dust penetration.

[0015] Example refer to Figures 1 to 4This embodiment of the communication-specific open-cut flame-retardant PPGFR high-strength waterproof and permeable double-interface conduit includes a first conduit 1 and a second conduit 2. The second conduit 2 is installed inside the first conduit 1. A support block 3 is threadedly connected to the outside of the first conduit 1. A sealing block 6 is fixedly connected to the outside of the second conduit 2. A first limiting block 7 is fixedly connected to the outside of the sealing block 6. A second limiting block 8 is threadedly connected to the top of the support block 3. A sleeve plate 15 is fixedly connected to one side of the second limiting block 8. A movable plate 19 is sleeved on one side of the sleeve plate 15. One side of the movable plate 19 is fixedly connected to the other side of the first limiting block 7. A telescopic rod 16 is fixedly connected to the top of the sleeve plate 15. A pressing plate 17 is fixedly connected to the top of the telescopic rod 16. A slot 20 is opened at the top of the movable plate 19. A connection between the bottom of the pressing plate 17 and the slot 20 is fixedly connected to the bottom of the pressing plate 17. The matching locking block 18 engages inside the locking slot 20. During use, due to the presence of the first limiting block 7 and the second limiting block 8, the distance between the first conduit 1 and the second conduit 2 can be effectively limited. When the movable plate 19 extends outward or retracts inward, the distance between the first conduit 1 and the second conduit 2 will change accordingly. The user can adjust the distance between the first conduit 1 and the second conduit 2 as needed. After the distance is adjusted, press the pressing plate 17 at the top of the telescopic rod 16, and the locking block 18 at the bottom of the pressing plate 17 can be inserted into the corresponding locking slot 20. This can effectively prevent the movable plate 19 from extending or retracting on its own, and can also effectively limit the distance between the first limiting block 7 and the second limiting block 8, which can effectively improve the stability between the first conduit 1 and the second conduit 2.

[0016] refer to Figure 1 Only Figure 3 A fixing block 10 is fixedly connected to the other side of the second limiting block 8. The bottom end of the fixing block 10 is in contact with the top end of the support block 3. A second screw hole 11 is provided at the top end of the fixing block 10. A second bolt 12 is threadedly connected to the inner side of the second screw hole 11. The bottom end of the second bolt 12 is in contact with the top end of the support block 3. The second limiting block 8 is threadedly connected to the top end of the support block 3 through the fixing block 10, the second screw hole 11, and the second bolt 12. Due to the presence of the second bolt 12, the screwing in of the second bolt 12 can effectively limit the position of the fixing block 10, and at the same time, it can also effectively limit the position of the second limiting block 8, thereby preventing the second limiting block 8 from shifting.

[0017] refer to Figure 1 and Figure 2 and Figure 4The top of the support block 3 has a groove 13, and a rubber pad 14 is fixedly connected to the inner side of the groove 13. The rubber pad 14 covers the inner side of the groove 13. The position of the top of the rubber pad 14 is symmetrical with the position of the bottom of the second bolt 12. Due to the presence of the rubber pad 14, when the second bolt 12 is screwed down, the top of the rubber pad 14 will come into contact with the bottom of the second bolt 12. The rubber pad 14 has good anti-slip ability, which can improve the stability of the fixed block 10 while also preventing the second bolt 12 from hitting the top of the support block 3.

[0018] refer to Figure 1 and Figure 2 The top of the support block 3 is provided with a groove 9 that matches the second limiting block 8. The bottom end of the second limiting block 8 is slidably connected to the inner side of the groove 9. Because of the opening of the groove 9, it is convenient for the user to adjust the position of the second limiting block 8. Adjusting the position of the second limiting block 8 to the end can achieve the effect of the first conduit 1 and the second conduit 2 being connected to each other.

[0019] refer to Figure 4 A sealing ring 21 is fixedly connected to the top of the first conduit 1, covering the top of the first conduit 1. The position of the sealing block 6 corresponds to the position of the first conduit 1. A sealing gasket 22 with a thickness of one centimeter is fixedly connected to the inner wall of the first conduit 1, covering the inner wall of the first conduit 1. A waterproof sleeve 23 with a thickness of one centimeter is fitted onto the inner wall of the second conduit 2, covering the inner side of the second conduit 2. To improve the waterproof capability of the first conduit 1 and the second conduit 2, the user can... The second limiting block 8 is pulled backward by the sliding groove 9, which facilitates the embedding of the second conduit 2 into the inner side of the first conduit 1. At the same time, the sealing block 6 will also fit against the top of the first conduit 1. Its sealing ring 21 can effectively seal the connection point between the sealing block 6 and the first conduit 1. The sealing gasket 22 on the inner wall of the first conduit 1 can fit tightly against the outer wall of the second conduit 2. Its waterproof sleeve 23 can fit tightly against the wires and cables installed inside the second conduit 2, thereby achieving a good sealing and waterproof effect and effectively preventing water or dust from penetrating.

[0020] refer to Figure 1On the other side of the support block 3, a first screw hole 4 is provided. The first screw hole 4 passes through the other side of the support block 3 and the first conduit 1. A first bolt 5 is threadedly connected to the inside of the first screw hole 4. One side of the first bolt 5 is threadedly connected to the inside of the first conduit 1 through the first screw hole 4. The support block 3 is threadedly connected to the outside of the first conduit 1 through the first bolt 5 and the first screw hole 4. Due to the presence of the first bolt 5, the position of the support block 3 can be effectively fixed by screwing in the first bolt 5, thereby preventing the support block 3 from shifting. When it is necessary to remove the support block 3, the first bolt 5 can be unscrewed out of the first screw hole 4. This also facilitates the user's later maintenance of the support block 3.

[0021] Operating principle and advantages: During use, the presence of the first limiting block 7 and the second limiting block 8 effectively limits the distance between the first conduit 1 and the second conduit 2. When the movable plate 19 extends outward or retracts inward, the distance between the first conduit 1 and the second conduit 2 changes accordingly. The user can adjust the distance between the first conduit 1 and the second conduit 2 as needed. After the distance is adjusted, pressing the pressing plate 17 at the top of the telescopic rod 16 will engage the locking block 18 at the bottom of the pressing plate 17 into the corresponding slot 20. This effectively prevents the movable plate 19 from extending or retracting on its own, and also effectively limits the distance between the first limiting block 7 and the second limiting block 8, thus effectively improving the stability between the first conduit 1 and the second conduit 2. Due to the presence of the second bolt 12, its tightening effectively limits the position of the fixed block 10, and also effectively limits the position of the second limiting block 8, thereby preventing displacement of the second limiting block 8. Due to the presence of the rubber pad 14, when the second bolt 12 is tightened downwards, the top of the rubber pad 14 will contact the bottom of the second bolt 12. The rubber pad 14 has good anti-slip ability, which improves the stability of the fixing block 10 and also prevents the second bolt 12 from hitting the top of the support block 3. To improve the waterproof ability of the first conduit 1 and the second conduit 2, the user can pull the second limiting block 8 backward through the sliding groove 9, which facilitates the embedding of the second conduit 2 into the inside of the first conduit 1. At the same time, the sealing block 6 will also fit against the top of the first conduit 1, and its sealing ring 21 can effectively seal the connection point between the sealing block 6 and the first conduit 1. The sealing gasket 22 on the inner wall can fit tightly against the outer wall of the second conduit 2, and its waterproof sleeve 23 can fit tightly against the wires and cables installed inside the second conduit 2, thereby achieving a good sealing and waterproof effect and effectively preventing water or dust from penetrating. Due to the presence of the first bolt 5, the screwing in of the first bolt 5 can effectively fix the position of the support block 3, thereby preventing the support block 3 from shifting. When it is necessary to remove the support block 3, the first bolt 5 can be screwed out of the first screw hole 4, which also facilitates the user to maintain the support block 3 later.
