Description

Technical Field

[0001] This utility model relates to the field of cable conduit technology, specifically a conduit. Background Technology

[0002] With continuous economic development and accelerated urbanization, the market demand for conduit is constantly increasing. Conduit, also known as insulated electrical conduit, is a type of pipe used for wiring that is corrosion-resistant, leak-proof, and for pulling electrical wires. It can be mainly divided into plastic conduit, stainless steel conduit, and carbon steel conduit. It is generally used for indoor wiring through walls or high-level cabling, effectively protecting cables. Existing technology discloses a conduit with authorization announcement number CN217590097U, comprising a main body; twelve internal partitions are fixedly installed inside the main body; a first connector is fixedly installed at the left end of the main body; a second connector is fixedly installed at the right end of the main body; a set of first positioning plates is fixedly installed on the rear left side of the first connector; a set of second positioning plates is fixedly installed on the front left side of the first connector; a positioning insert is fixedly installed on both the front and rear sides of the second connector; and a locking bracket is installed on the outer top of the second connector. The wires will not get tangled when pulling or threading them through the machine, making the operation more convenient and effectively preventing wire misalignment during connection.

[0003] However, existing conduits have been found to lack cable pulling and threading mechanisms, requiring manual threading. This often results in cable ends getting blocked and unable to pass through the conduit, frequently necessitating multiple threading attempts and causing significant inconvenience to cable installation. Utility Model Content

The third sliding grooves are opened on the inner wall of the T-shaped limiting plate near the square tube. A third slider is slidably installed in the third sliding groove. A lead screw is threaded through the third slider. Both ends of the lead screw extend to the outside of the T-shaped limiting plate. The third slider is fixed on the corresponding sliding plate.

[0008] The beneficial effect of this improvement is that, by setting it up in this way, the slide can be moved, which makes it easier to pull the end of the cable into the square tube and bring it closer to the other end, thereby enabling the cable to be threaded quickly.

[0009] To facilitate clamping cables of different thicknesses:

[0010] As a further improvement to the above technical solution: an arc-shaped groove is provided on the clamping block, and an arc-shaped anti-slip pad is provided on the inner wall of the arc-shaped groove.

[0011] The beneficial effect of this improvement is that by setting an arc-shaped slot, it is easier to clamp cables of different thicknesses.

[0018] To facilitate the movement of the third slider driven by the lead screw:

[0019] As a further improvement to the above technical solution: the third slider has a second threaded through hole, and the lead screw thread passes through the second threaded through hole.

[0020] The beneficial effect of this improvement is that by setting a second threaded through hole, it is easier for the lead screw to drive the third slider.

[0021] To facilitate the support and limiting of the lead screw:

[0022] As a further improvement to the above technical solution: the inner walls on both sides of the third slide groove are provided with second through holes, and the lead screw rotates through the two second through holes.

[0023] The beneficial effect of this improvement is that by setting a second through hole, it is easier to support and limit the lead screw.

[0024] The beneficial effects of this utility model are as follows: through a simple wire end clamping and pulling structure, it is easy to pull and thread the cable, which can effectively avoid the problem of the cable end being blocked in the conduit and unable to be threaded out, and avoid the problem of multiple attempts to thread the cable, thus bringing great convenience to the cable laying work.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] like Figure 1-6As shown, a conduit includes a square tube 1, with a cross-shaped partition 2 inside the square tube 1. Two fixing feet 3 are fixedly installed on both sides of the square tube 1. T-shaped limiting plates 4 are fixedly installed on the top and bottom of the square tube 1. Two sliding plates 5 are slidably installed on the top and bottom of the square tube 1, and the sliding plates 5 are slidably connected to the corresponding T-shaped limiting plates 4. Two rectangular through slots 6 are penetrated on the inner walls of the top and bottom of the square tube 1. A first sliding groove 7 is opened at the bottom of the sliding plate 5, and two first sliders 8 are slidably installed in the first sliding groove 7. A clamping block 9 is fixedly installed at the bottom of the first slider 8, and the clamping block 9 penetrates the corresponding rectangular through slot 6. Two clamping blocks 9 located in the same rectangular through slot 6 are compatible. The sliding plate 5... A bidirectional lead screw 10 is rotatably installed, and the bidirectional lead screw 10 is threaded through two first sliders 8. Two second sliding grooves 11 are provided on the T-shaped limiting plate 4, and second sliders 12 are slidably installed within the second sliding grooves 11. The second sliders 12 are fixed on corresponding sliding plates 5. Through a simple wire end clamping and pulling structure, it is convenient to pull and thread the cable, effectively avoiding the problem of the cable end being blocked inside the conduit and preventing multiple attempts at threading, thus greatly facilitating cable laying. The T-shaped limiting plate 4 also includes two third sliding grooves 13, which are provided on the inner wall of the T-shaped limiting plate 4 near the square tube 1. Third sliders 14 are slidably installed within the third sliding grooves 13. The third slider 14 is threaded with a lead screw 15, both ends of which extend beyond the T-shaped limiting plate 4. The third slider 14 is fixed to the corresponding slide plate 5. This arrangement allows for movement of the slide plate 5, facilitating the pulling of the cable end into the square tube 1 and closer to the other end, thus enabling rapid cable threading. The clamping block 9 has an arc-shaped groove with an arc-shaped anti-slip pad on its inner wall. This arc-shaped groove facilitates clamping cables of different thicknesses. The inner walls of the first slide groove 7 have a first through hole and a circular groove, respectively. One end of the bidirectional lead screw 10 rotates through the first through hole, and the other end of the bidirectional lead screw 10 rotates and is installed in the circular groove. The first through hole and the circular groove facilitate the support and limiting of the bidirectional lead screw 10. The fixed foot 3 has multiple circular holes, the first slider 8 has a first threaded through hole, and the bidirectional lead screw 10 is threaded through two first threaded through holes. The first threaded through holes facilitate the movement of the first slider 8 driven by the bidirectional lead screw 10. The third slider 14 has a second threaded through hole, and the lead screw 15 is threaded through the second threaded through hole. The second threaded through hole facilitates the movement of the third slider 14 driven by the lead screw 15. The inner walls of both sides of the third sliding groove 13 have second through holes, and the lead screw 15 rotates through two second through holes. The second through holes facilitate the support and limiting of the lead screw 15.

[0034] The working principle of this utility model is as follows: In use, first insert the cable end into one end of the square tube 1, placing the cable end between the two corresponding clamping blocks 9. Then, rotate the corresponding bidirectional lead screw 10. The bidirectional lead screw 10 drives the two first sliders 8 to slide within the first slide groove 7 and move closer to each other. The two first sliders 8 drive the two clamping blocks 9 laterally and move closer to each other until the cable end is clamped by the two clamping blocks 9. Then, rotate the corresponding lead screw 15. The lead screw 15 drives the third slider 14 to slide within the third slide groove 13 towards the other end of the square tube 1. Simultaneously, the third slider 14 drives the sliding plate 5 to slide on the T-shaped limiting plate 4. At the other end of tube 1, the slide plate 5 drives the second slider 12 to slide in the second slide groove 11. As the slide plate 5 moves, it drives the two clamping blocks 9 to move in the rectangular through groove 6 to the other end of the square tube 1. The two clamping blocks 9 pull the end of the cable into the square tube 1 and close to the other end, so that the cable passes through the square tube 1. Then, the bidirectional screw 10 is rotated in the opposite direction, so that the cable is released by the two clamping blocks 9. With this setting, it is easy to pull and thread the cable, which can effectively avoid the problem that the end of the cable is blocked in the conduit and cannot be threaded out, and avoid the problem of multiple attempts to thread the cable, which brings great convenience to the cable laying work.
