[0002] Power cables are cable products used to transmit and distribute electrical energy, playing a vital role in power systems. Plastic conduits for power cables are important materials used in power engineering to protect cables.
[0003] Most of the existing plastic conduits for power cables are spliced using heat fusion. However, heat fusion requires heating two sets of plastic conduits with a heat fusion tool, which is a cumbersome process and makes it inconvenient to position and splice the two plastic conduits.
[0004] Therefore, it is necessary to invent a plastic conduit for power cables that is easy to position and splice in order to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a plastic conduit for power cables that is easy to position and splice. By inserting the mating plates on both sides of the second connecting kit at one end of the secondary plastic conduit body into the mating block of the first connecting kit at the other end of the main plastic conduit body to form a positioning connection, and then using bolts to pass through the mating block and the mating plate, the main plastic conduit body and the secondary plastic conduit body can be easily spliced. Compared with the traditional hot fusion, it is faster and solves the problem mentioned in the background art that most splicing of existing plastic conduits for power cables adopts hot fusion connection. Hot fusion connection requires the use of hot fusion tools to heat the two sets of plastic conduits, and the splicing process is relatively cumbersome and inconvenient for positioning and splicing the two plastic conduits.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic conduit for power cables that is easy to position and splice, comprising a main plastic conduit body for sleeved protection of power cables;
[0007] The first connecting kit is fixed to one end of the main plastic conduit body for splicing. One end of the main plastic conduit body is movably connected to a secondary plastic conduit body, and the other end of the secondary plastic conduit body is fixedly connected to a second connecting kit. Both sides of the second connecting kit are fixedly connected to mating blocks. Slots are provided on the inner surface of the first connecting kit. Movable blocks are slidably connected inside the first connecting kit. Connecting blocks are fixedly connected to the inner side of the movable blocks. Springs are fixedly installed on the lower side of the connecting blocks. Clamping blocks are fixedly connected to the lower end of the movable blocks. Connecting rods are fixedly connected to the inner side of the second connecting kit. Connecting plates are fixedly connected to both sides of the second connecting kit. Bolts penetrate the outer side of the connecting plates.
[0008] Preferably, a sealing groove is formed on the inner surface of the first connecting kit, and a sealing ring is embedded inside the sealing groove.
[0009] Preferably, the docking rods are arranged in a circular array on the second connecting kit, and the docking rods are movably docked with the slots on the inner side of the first connecting kit.
[0010] Preferably, one end surface of the docking rod is inclined, and the inner surface of the moving block is set as an inclined surface.
[0011] Preferably, the clamping blocks are slidably connected to the first connecting kit via connecting blocks, and the clamping blocks are arranged in a ring array within the first connecting kit.
[0012] Preferably, the mating plates on both sides of the second connecting kit are movably engaged with the mating blocks on both sides of the first connecting kit, and the bolts pass through the inner sides of the mating blocks and mating plates.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. By setting up the main plastic conduit body, the first connecting kit, the secondary plastic conduit body, the second connecting kit, the mating block, the mating plate, and the bolts, when splicing is required, the mating plates on both sides of the second connecting kit at one end of the secondary plastic conduit body are inserted into the mating block of the first connecting kit at the other end of the main plastic conduit body to form a positioning mating. Then, the bolts are used to pass through the mating block and the mating plate, making it easier to splice the main plastic conduit body and the secondary plastic conduit body. This is faster than traditional hot melt splicing.
[0015] 2. Through the arrangement of the first connecting kit, the second connecting kit, the slot, the moving block, the connecting block, the spring, and the clamping block, when the mating rod inside the second connecting kit is inserted into the slot inside the first connecting kit, it squeezes the moving block and the inner spring, causing the moving block to push multiple sets of clamping blocks to clamp the electronic cable inside the main plastic conduit body and the auxiliary plastic conduit body, thereby facilitating the positioning of the electronic cable.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] This utility model provides, for example Figure 1-5 The illustrated plastic conduit for power cables, which is easy to position and splice, includes a main plastic conduit body 1 for mounting and protecting power cables.
[0026] The first connecting kit 2 is fixed to one end of the main plastic conduit body 1 for splicing. One end of the main plastic conduit body 1 is movably connected to the secondary plastic conduit body 3. The other end of the secondary plastic conduit body 3 is fixedly connected to the second connecting kit 4. The two sides of the second connecting kit 4 are fixedly connected to the mating blocks 7. The inner surface of the first connecting kit 2 is provided with slots 8. The inside of the first connecting kit 2 is slidably connected to the moving blocks 9. The inner side of the moving blocks 9 is fixedly connected to the connecting blocks 10. The lower side of the connecting blocks 10 is fixedly provided with springs 11. The lower end of the moving blocks 9 is fixedly connected to clamping blocks 12. The inner side of the second connecting kit 4 is fixedly connected to the mating rods 13. The two sides of the second connecting kit 4 are fixedly connected to the mating plates 14. The outside of the mating plates 14 is penetrated by bolts 15. Most of the existing plastic conduits for power cables are spliced using heat fusion connection. However, heat fusion connection requires the use of heat fusion tools to heat the two sets of plastic conduits. The splicing process is relatively cumbersome and it is not convenient to position and splice the two plastic conduits.
[0027] like Figure 1 and Figure 2As shown, a sealing groove 5 is provided on the inner surface of the first connecting kit 2, and a sealing ring 6 is embedded inside the sealing groove 5. By providing a sealing ring 6 between the first connecting kit 2 and the second connecting kit 4, the sealing between the connection can be enhanced, and a waterproof effect can be achieved.
[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the docking rods 13 are arranged in a ring array on the second connecting kit 4. The docking rods 13 are movably docked with the slots 8 inside the first connecting kit 2. The docking rods 13 inside the second connecting kit 4 are inserted into the slots 8 inside the first connecting kit 2 to form a docking positioning effect.
[0029] like Figure 3 and Figure 5 As shown, one end of the docking rod 13 is inclined, and the inner surface of the moving block 9 is set as a slope. The docking rod 13 is inserted into the slot 8 inside the first connecting kit 2, so that the inclined setting of one end of the docking rod 13 pushes the slope of the inner side of the moving block 9 to squeeze, so that the moving block 9 moves in and out within the first connecting kit 2, thereby pushing the lower clamping block 12 to clamp and position the cable.
[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the clamping block 12 is slidably connected to the first connecting kit 2 via the connecting block 10. The clamping blocks 12 are arranged in a ring array within the first connecting kit 2. By moving multiple sets of clamping blocks 12 inward simultaneously, the cable inside the main plastic conduit body 1 is positioned and clamped.
[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the mating plates 14 on both sides of the second connecting kit 4 are movably engaged with the mating blocks 7 on both sides of the first connecting kit 2. The bolts 15 pass through the inner sides of the mating blocks 7 and the mating plates 14. The mating is formed by inserting the mating plates 14 into the inner sides of the mating blocks 7, and then the bolts 15 pass through the two for positioning and splicing. This is more convenient and faster than traditional hot melt.
[0032] The working principle of this utility model is as follows: First, the second connecting kit 4 at one end of the auxiliary plastic conduit 3 is connected to the first connecting kit 2 at the other end of the main plastic conduit 1. When the first connecting kit 2 is connected, the connecting plates 14 on both sides are inserted into the connecting blocks 7 on both sides of the second connecting kit 4 to form a positioning splice. When the second connecting kit 4 is connected to the first connecting kit 2, the connecting rod 13 on the inner side of the second connecting kit 4 is inserted into the slot 8 on the inner side of the first connecting kit 2, so that the connecting rod 13 presses the inclined surface on the inner side of the moving block 9, causing the moving block 9 to press against the inner spring 11, so that the moving block 9 pushes multiple sets of clamping blocks 12 to move inward, thereby clamping the electronic cable in the main plastic conduit 1 and the auxiliary plastic conduit 3, thus facilitating the positioning of the electronic cable. Finally, the bolt 15 is used to pass through the connecting block 7 and the inner side of the connecting plate 14 to splice the main plastic conduit 1 and the auxiliary plastic conduit 3. In this way, the use process of this plastic conduit for power cables that is easy to position and splice is completed.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
