Description

Technical Field

[0001] This utility model relates to the field of electrical equipment protection technology, and in particular to assembled power cable conduits. Background Technology

[0002] A power cable is a combination of conductors used to transmit electrical energy. It typically consists of one or more insulated cores surrounded by a protective sheath. The cores are generally made of highly conductive metals such as copper or aluminum, while the insulation material can be polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), etc., which prevents current leakage and short circuits between the cores. However, modern building and industrial environments are increasingly complex. In buildings, cables need to pass through walls, ceilings, floors, and other structural elements, and navigate around beams, columns, pipes, and other obstacles. In industrial settings, cables must be laid between large equipment, shelving, and conveyor belts. Modular conduits can flexibly change their laying direction using various connecting components, easily adapting to these complex environments.

[0003] Most cable conduits consist of a conduit body, connecting pipes, and mounting rods. The conduit is assembled by inserting the cable into it and then connecting the conduits through the connecting pipes. This not only provides better protection for the cable but also improves the flexibility of cable laying.

[0004] In existing technologies, when two conduits are connected by a connecting tube, a sealing ring is usually used to seal the connection between them. However, during long-term use, environmental factors such as temperature changes and vibrations can reduce the sealing performance of the sealing ring, making it easier for external moisture to enter the conduit and increasing the risk of cable damage. Therefore, to address these shortcomings, an assembled power cable conduit is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an assembled power cable conduit. This conduit aims to improve the problem that the sealing performance of the sealing ring is reduced due to environmental factors, allowing external moisture to easily enter the conduit and increasing the risk of cable damage.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An assembled power cable conduit includes two conduit bodies and a connecting pipe. The conduit bodies are connected to the connecting pipe via a connecting assembly. The connecting assembly has receiving holes on both its left and right sides. Multiple fixing rods are fixedly connected to one side of each receiving hole. A telescopic spring is sleeved on the outside of each fixing rod. Connecting rings are slidably connected to the inner walls of both sides of the connecting assembly. A sliding hole is opened inside one side of each connecting ring. A sealing ring I is fixedly connected to the far side of each of the two connecting rings, and a limit ring is fixedly connected to the near side of each of the two connecting rings. A sealing ring II is fixedly connected to the side of the conduit body that contacts the connecting pipe. An installation rod is fixedly connected to the bottom end of the conduit body.

[0008] Furthermore, two telescopic rods are fixedly connected to the bottom of the inner side of the catheter body, a strong spring is sleeved on the outside of the telescopic rod, a force-bearing block is fixedly connected to the top of the telescopic rod, a tightening assembly is threadedly connected to the inner wall of the catheter body, and a squeezing block is rotatably connected to the bottom of the tightening assembly.

[0009] Furthermore, the connecting assembly includes two connecting blocks, a connecting disc is fixedly connected to the adjacent side of the two connecting blocks, a screwing rod is fixedly connected to the outside of the connecting disc, the inside of the connecting disc is opened outside the receiving hole, the outside of the connecting ring is slidably connected to the inner wall of one side of the connecting disc, and the outside of the two connecting blocks is respectively threaded to the inside of the adjacent side of the conduit body and the connecting tube.

[0010] Furthermore, one end of the telescopic spring is fixedly connected to the inside of the receiving hole, and the other end of the telescopic spring is fixedly connected to one side of the limiting ring.

[0011] Furthermore, the outer part of the limiting ring is slidably connected to the inside of the receiving hole, and one side of the sealing ring one is in contact with one side of the sealing ring two.

[0012] Furthermore, the outer part of the fixing rod is slidably connected to the inside of the sliding hole, and the outer part of the fixing rod is slidably connected to the inside of the limiting ring.

[0013] Furthermore, the outer side of the extrusion block is in contact with the inner top of the force-receiving block, and a gasket is provided on the adjacent side of both the extrusion block and the force-receiving block.

[0014] Furthermore, the tightening assembly includes multiple force-applying rods, the bottom end of which is rotatably connected to the top end of the extrusion block, the external thread of which is connected to the inside of the guide tube body, and a tightening disc is fixedly connected to the top end of which.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by turning the turning rod, the connecting plate drives the two connecting blocks to connect the conduit body with the connecting pipe. During this process, the sealing ring one and the sealing ring two come into contact. This process also causes the telescopic spring to be stressed, generating a rebound force that makes the sealing ring one and the sealing ring two come into tight contact. This reduces the possibility of external moisture entering the conduit, reduces the risk of cable damage caused by external factors, and ensures the safe and stable operation of the cable.

[0017] 2. In this utility model, turning the turning disc causes the force-applying rod to drive the extrusion block to move the cable toward the force-receiving block, and causes the strong spring to be stressed, generating a rebound force to bounce the force-receiving block back, which can ensure that the cable will not move randomly in the conduit, thereby improving the stability of cable laying.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 3This utility model provides an embodiment of an assembled power cable conduit, comprising two conduit bodies 1, which bear the important responsibility of providing the main containment and protection space for the cable in the entire cable conduit system, and a connecting pipe 2. The conduit body 1 is connected to the connecting pipe 2 through a connecting assembly. The connecting assembly has receiving holes 5 on both sides. Multiple fixing rods 6 are fixedly connected to one side of each receiving hole 5. These fixing rods 6 provide a stable guide and support foundation for subsequent structural movement. A telescopic spring 7 is sleeved on the outside of the fixing rods 6. The inner walls of both sides of the connecting assembly are slidably connected to the connecting ring 8. This sliding connection ensures that the connecting ring 8 can move flexibly within a certain range. The connecting assembly includes two connecting blocks 3. A connecting plate 4 is fixedly connected to the adjacent side of the two connecting blocks 3. A turning rod 20 is fixedly connected to the outside of the connecting plate 4. The turning rod 20 is a key part of the operation, which facilitates the user to apply force. The inside of the connecting plate 4 is cleverly opened outside the receiving hole 5. The outside of the connecting ring 8 is slidably connected to the inner wall of one side of the connecting plate 4.

[0026] The two connecting blocks 3 are threadedly connected to the interior of the conduit body 1 and the connecting pipe 2 on the adjacent sides, ensuring a secure connection while facilitating installation and disassembly. A sliding hole 9 is provided inside one side of the connecting ring 8, and a sealing ring 10 is fixedly connected to its opposite side. The sealing ring 10 is a crucial defense against external substances entering the conduit. Limiting rings 11 are fixedly connected to the adjacent sides of both connecting rings 8, effectively restricting the movement range of the relevant structures. One end of the telescopic spring 7 is fixedly connected to one side of the inside of the receiving hole 5, and the other end is fixedly connected to one side of the limiting ring 11. The outside of the limiting ring 11 slides inside the receiving hole 5. The outside of the fixing rod 6 slides inside the sliding hole 9 and the limiting ring 11. A sealing ring 2 12 is fixedly connected to the side of the conduit body 1 that contacts the connecting pipe 2. The sealing ring 2 12 and the sealing ring 10 work together to form a sealing protection system. One side of the sealing ring 10 contacts one side of the sealing ring 2 12. An installation rod 13 is fixedly connected to the bottom end of the conduit body 1. The installation rod 13 provides a convenient connection point for the installation and fixation of the conduit body 1.

[0027] Reference Figure 1 , Figure 2 and Figure 4Two telescopic rods 14 are fixedly connected to the bottom of the inner part of the conduit body 1. The telescopic rods 14 can extend and retract within a certain range to change their length. A strong spring 15 is sleeved on the outside of the rod. The strong spring 15 can generate a strong rebound force after being deformed by force. A force-bearing block 16 is fixedly connected to the top of the telescopic rod 14. The force-bearing block 16 is a component that directly contacts the cable and applies force to it. The inner wall of the conduit body 1 is connected to the tightening assembly by a threaded connection. The bottom end of the tightening assembly is rotatably connected to the squeezing block 18. The tightening assembly includes multiple force-applying rods 17. The bottom end of the force-applying rod 17 is flexibly rotatably connected to the top end of the squeezing block 18. This rotatable connection allows the force-applying rod 17 to effectively drive the squeezing block 18 to move accordingly during rotation. The outside of the force-applying rod 17 is precisely threaded to the inside of the conduit body 1. The top end of the force-applying rod 17 is fixedly connected to the screwing disc 19, which provides a convenient point of force application. The outside of the squeezing block 18 is in contact with the inside of the top end of the force-receiving block 16. Gaskets are provided on the side of the squeezing block 18 and the force-receiving block 16 that are close to each other. The gaskets can play multiple roles such as buffering, protection and enhancing contact stability.

[0028] Working Principle: First, rotating the turning rod 20 causes the connecting plate 4 to rotate. This rotation causes the two connecting blocks 3, which are fixedly connected to it, to rotate as well. Since the two connecting blocks 3 are threadedly connected to the conduit body 1 and the connecting pipe 2 respectively, the rotation of the connecting blocks 3 causes them to slide threadedly inside the conduit body 1 and the connecting pipe 2, thereby bringing the conduit body 1 and the connecting pipe 2 closer together and connecting them. During this process, the connecting plate 4 pushes the connecting ring 8 to slide on one side of its inner wall. The sealing ring 10 on one side of the connecting ring 8 contacts the sealing ring 12 on the conduit body 1 or the connecting pipe 2. Simultaneously, the limiting ring 11 inside the connecting ring 8 slides inside the receiving hole 5, and the fixing rod 6 slides inside the sliding hole 9 and the limiting ring 11. The telescopic spring 7 is compressed and generates a rebound force, which ensures that the sealing ring 10 and the sealing ring 12 are in tight contact, reducing the possibility of external moisture entering the conduit and minimizing the risk of cable damage caused by external factors, thus ensuring the safe and stable operation of the cable.

[0029] The cable is placed inside the conduit body 1, above the force-bearing block 16. Then, the rotating disc 19 is turned, causing the force-applying rod 17 to rotate. The force-applying rod 17 slides threadedly inside the conduit body 1, causing the compression block 18 to move downwards. The compression block 18 applies pressure to the cable towards the force-bearing block 16, causing the cable to move in that direction. At this time, the high-strength spring 15 is compressed. When the external force disappears, the high-strength spring 15 generates a rebound force, causing the force-bearing block 16 to spring back, thus firmly fixing the cable between the force-bearing block 16 and the compression block 18, ensuring that the cable will not shift arbitrarily within the conduit and improving the stability of cable laying.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
