Description

Technical Field

[0001] The present invention relates to the field of cable laying auxiliary technology, in particular to a high-rigidity double-wall cylinder and a torsion-resistant cable reel structure. Background Art

[0002] Flat cables are flat cables with a width significantly greater than their thickness. They consist of multiple conductors arranged in parallel, surrounded by insulation and a sheath. Their flat design offers unique advantages in applications where space is limited and flexible wiring is required.

[0003] During the flat cable installation process, cable reels are key tools for supporting, storing, transporting, and laying out cables. When multiple cables are located in the same area (such as in data centers and control cabinet clusters), flat cables need to be laid overhead. For example, overhead installation using cable trays or trunking can avoid spatial conflicts with ground-level pipes and equipment bases, facilitate line classification and management, and reduce electromagnetic interference. Furthermore, elevated flat cables are typically secured with brackets or suspension systems, allowing maintenance personnel to access them directly using ladders or lifting equipment, eliminating the need to remove floor coverings or dismantle equipment, thus improving maintenance efficiency.

[0004] Because cables are heavy during cable laying, highly rigid cylindrical reels are often used for cable transportation. Their high rigidity prevents deformation and damage, and they can effectively increase the length of stored cable. During the laying process, when flat cables are pulled from the reel, the metal and insulating materials (such as polyethylene and cross-linked polyethylene) in the cable have a certain elastic memory effect. After being bent for a long time, they tend to naturally bend, causing inconvenience during the laying process. Furthermore, during high-level laying, when the flat cable is pulled in an inclined direction, it can easily scrape against the anti-slip wall panels on the reel, damaging the edges of the flat cable. Furthermore, because the cable is flat, it can easily twist and deform when scraped, affecting the structure. Furthermore, when not being laid and moved, the reel can easily rotate naturally, causing the cable to fall off. Therefore, a high-rigidity double-walled cylindrical and torsion-resistant cable reel structure was proposed. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0032] like Figures 1-8The high-rigidity double-wall cylinder and torsion-resistant cable drum structure shown in the figure include a frame plate 1, which is provided with two frame plates 1, and a plurality of connecting frames 2 are fixedly connected between the two frame plates 1, and a cable drum 5 is installed between the two frame plates 1 for common rotation, and the two ends of the cable drum 5 are respectively fixedly connected to the anti-slip wall plate 6, and the two frame plates 1 are close to each other and are located in front of the cable drum 5 and are respectively rotatably connected to the rotating shaft 27, and the lower surface of each rotating shaft 27 is respectively connected to the friction plate 32 through an elastic mechanism, and the friction plate 32 squeezes the side of the anti-slip wall plate 6, and the rear lower edge of the friction plate 32 is fixedly connected to the curved plate 33, and the ends close to the two rotating shafts 27 are commonly fixedly connected to the arc rail 13, and the outer surface of the arc rail 13 is slidingly sleeved with a slider 14, and the upper surface of the slider 14 is rotatably provided with a lower roller 17, and the upper surface of the lower roller 17 is provided with an upper roller 19 through a distance adjustment mechanism, and the upper surface of the slider 14 and the two sides in front of the lower roller 17 are respectively rotatably provided with a rotating cylinder 22;

[0033] After the flat cable 38 is pulled out from the surface of the cable drum 5, the bent memory portion 39 at the pulled-out position is pressed between the lower roller 17 and the upper roller 19 to form a reset portion 40;

[0034] When the flat cable 38 is pulled out, the arc rail 13 is driven to rotate toward the front and upward direction, and the friction plate 32 is rotated and moves away from the side of the anti-slip wall plate 6.

[0035] like Figure 1 、 Figure 2 、 Figure 7 As shown, the upper sides of the two frame plates 1 are fixedly mounted with an insertion shaft 8, and the cable drum 5 is rotatably sleeved on the outer surface of the insertion shaft 8. The cable drum 5 can be rotated relative to the insertion shaft 8 to ensure that the flat cable 38 can be pulled out.

[0036] A support opening 10 is provided on the upper side of the frame plate 1, and the end of the insertion shaft 8 is slidably inserted into the inner side of the support opening 10. Positioning plates 11 are respectively provided on the upper side of the one side surface of the frame plate 1, and limiting grooves 9 are respectively provided at both ends of the outer surface of the insertion shaft 8. The lower side of the positioning plate 11 slides into the inner side of the limiting groove 9, and the front and rear edges of one side surface of the positioning plate 11 are slidably inserted into the limiting bolt 12. The end of the limiting bolt 12 is threadedly inserted into the outer surface of the frame plate 1, and a stabilizing head 7 is fixedly connected to the center of one side surface of the anti-slip wall plate 6. The stabilizing head 7 is designed in a truncated cone shape, so that the end can be slightly stuck into the inner side of the support opening 10, thereby ensuring the stability of the wire drum 5 to avoid the problem of the wire drum 5 shaking in both directions.

[0037] Because the positioning plate 11 is stuck in the limiting groove 9, the plug shaft 8 will not rotate relative to the support mouth 10, ensuring the stability of the plug shaft 8. After unscrewing the limiting bolt 12, the positioning plate 11 can be removed, and then the lower plug shaft 8 can be pulled up and out to replace the cable reel 5. Replacing the cable reel 5 with the coiled cable is easy.

[0038] like Figure 3 、 Figure 4 、 Figure 5 As shown, the elastic mechanism includes a connecting block 29 fixedly connected to the lower surface of the rotating shaft 27. The lower end of the connecting block 29 is fixedly connected to a connecting plate 30. The lower surface of the connecting plate 30 is fixedly mounted with a sealing plate 31. The inner sides of the connecting plate 30 and the sealing plate 31 have at least two slots 35. A side surface of the friction plate 32 is fixedly connected to a plurality of movable rods 34. One end of the movable rod 34 is fixedly connected to an anti-slip disk 36. One end of the movable rod 34 slides into the inner side of the slot 35, and the anti-slip disk 36 slides with the inner wall of the slot 35. A compression spring 37 is provided inside the slot 35, and one end of the compression spring 37 abuts against the end face of the anti-slip disk 36. The connecting block 29 is used to provide an appropriate height to ensure that the friction plate 32 is at an appropriate height position so that it can be attached to the side of the anti-slip wall plate 6. The sealing plate 31 can be fixedly mounted between the connecting plate 30 using bolts to facilitate the replacement and arrangement of components such as the movable rod 34 and the compression spring 37.

[0039] like Figure 3 、 Figure 4 As shown, the adjacent ends of the two rotating shafts 27 are fixedly connected to end blocks 28, and the upper ends of the curved rails 13 are fixedly connected to the lower surfaces of the end blocks 28. The large surface area of the end blocks 28 ensures a secure connection with the curved rails 13. The rear surface of the slider 14 is provided with a bayonet 15, which is slidably mounted on the outer surface of the curved rails 13. The bayonet 15 has a convex cross-section to ensure that the slider 14 can slide relative to the curved rails 13 without separating.

[0040] like Figure 6 As shown, two connecting seats 16 are fixedly connected to the upper surface of the slider 14, and both ends of the lower roller 17 are rotatably connected to the connecting seats 16 respectively.

[0041] The pitch adjustment mechanism includes a lifting base 18 that rotatably fits over the outer surface of the upper roller 19. An upper connecting block 24 is fixedly connected to a corner of the lifting base 18. A lower connecting block 23 is fixedly connected to a corner of the slider 14. A threaded rod 25 is threaded through the upper surface of the lower connecting block 23. The lower end of the threaded rod 25 is fixedly connected to a polygonal block 26, and the upper end of the threaded rod 25 is rotatably connected to the upper connecting block 24. Using a tool such as a wrench, the polygonal block 26 can be rotated, thereby rotating the threaded rod 25, causing it to move upward or downward relative to the lower connecting block 23. The corners of the upper and lower connecting blocks 24 and 23 are designed to ensure that the threaded rod 25 avoids the position of the curved rail 13, preventing interference between the structures.

[0042] Two guide posts 20 are fixedly connected to the upper surface of the slider 14. Two rotating cylinders 22 are slidably mounted on the outer surfaces of the guide posts 20. The upper ends of the rotating cylinders 22 are rotatably connected to connecting blocks 21. The corners of the connecting blocks 21 are fixedly connected to the side surfaces of the lifting base 18. The two guide posts 20 serve as guides to ensure stability when the upper roller 19 moves up and down for pitch adjustment. The rotating cylinders 22 can rotate relative to the connecting blocks 21. When the flat cable 38 is pulled, both sides contact the rotating cylinders 22, effectively preventing wear.

[0043] like Figure 1 As shown, the front and rear ends of the lower surface of the frame plate 1 are respectively rotatably mounted with wheel bodies 3, and a push frame 4 is fixedly mounted at the rear edge between the two frame plates 1. The push frame 4 is convenient for the user to push the whole, and cooperates with the wheel body 3 to make the whole move convenient.

[0044] like Figure 8 As shown, when the user is laying the flat cable 38 at a high position, he pulls the cable toward the front and top. After the flat cable 38 is pulled out from the surface of the cable drum 5, the pulling-out point is the bending memory part 39, which is pressed between the lower roller 17 and the upper roller 19 to form the reset part 40, effectively reducing the degree of bending.

[0045] During the pulling-out process, as the user's laying position changes, the flat cable 38 will be pulled in the oblique forward direction. At this time, the slider 14 will slide relatively along the surface of the arc rail 13 and change its position, thereby ensuring that the flat cable 38 will not directly scrape against the frame 1, anti-slip wall plate 6 and other structures during the laying process. During the laying process, since the side of the flat cable 38 will be guided and transported by the rotating drum 22, the problem of scratching and deformation of the side of the flat cable 38 can be effectively reduced, which is suitable for the stable transportation and laying of the flat cable 38.

[0046] The user rotates the polygonal block 26 to rotate the threaded rod 25, which moves up and down relative to the lower connecting block 23, thereby causing the upper connecting block 24 to move up and down synchronously, thereby changing the spacing between the upper roller 19 and the lower roller 17, preventing the gap between the flat cable 38 from being too large, which would cause the flat cable 38 to be torsionally damaged between the upper roller 19 and the lower roller 17, thereby improving the adaptability of use.

[0047] In the process of pulling out the flat cable 38, due to the high laying position, the curved rail 13 and the slider 14 will rotate toward the front and top. At this time, the friction plate 32 will move away from the anti-stripping wall plate 6, thereby relaxing and no longer restricting the anti-stripping wall plate 6, ensuring that the cable drum 5 can rotate when the flat cable 38 is pulled, and the flat cable 38 can be pulled out. When laying is no longer performed, due to the action of gravity, the curved rail 13 naturally rotates downward, and the friction plate 32 rotates toward the rear and bottom. The curved plate 33 first contacts the anti-stripping wall plate 6 and is pushed relatively, squeezing the compression spring 37, thereby causing the friction plate 32 to move to one side of the anti-stripping wall plate 6. At this time, the friction plate 32 contacts the side of the anti-stripping wall plate 6, which plays a limiting role, effectively preventing the problem of natural rotation of the cable drum 5. When the cable is not laid, it has an automatic limiting function and is convenient to use.

[0048] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
