[0002] The mobile power supply wire hanging frame is mainly used for power supply of mobile equipment, and mainly installs cables in sections in the trolley on the wire hanging frame. When the mobile equipment moves, the cables are pulled to drive the trolley to slide in the I-shaped steel, so that the cables are synchronized with the wire laying and winding, the movement of the mobile equipment is avoided, and the neatness of the power supply cables is ensured.

[0003] The prior art discloses a flat cable sliding rail trolley, which is characterized in that limiting sliding grooves are arranged in the interiors of the two sides of the sliding rail frame and the limiting frame, so that the overall stability is higher when the sliding wheels are installed and fixed, the sliding wheels are not easy to fall off during movement, the overall operation is more stable, the distance between the sliding rail frame and the limiting frame can be adjusted through the limiting frame and the limiting bolt, the sliding wheels can be disassembled and assembled, the limiting frame is arranged in a section-by-section mode, the sliding can be disassembled and replaced in the later period, the overall operation is simple, and the overall working efficiency is improved.

[0004] Although the sliding wheels can be disassembled and assembled in the later period, there are certain defects in actual use. In order to prevent the cables from sliding randomly due to transverse movement during installation of the cables, the sliding wheels that are suitable in size for the cables are selected. However, when other electrical elements are installed to increase the cables in the later period, the existing sliding wheels cannot be expanded according to the increased cables, so it is necessary to replace all the sliding wheels with the sliding wheels that are suitable in size for the increased cables, the convenience of the device is greatly reduced, and the installation difficulty of the equipment is increased.

The expansion mechanism includes a lower arc-shaped plate, a mounting box, and a lower extrusion plate. The lower extrusion plate is located at the bottom of the mounting box. A pair of bolts are threaded through the top of the lower extrusion plate, and the bottom of the bolts is threaded through the lower arc-shaped plate to a lower nut. The mounting box is located between the upper screws, and a lead screw is threaded through the side wall of the mounting box. A conical block is rotatably connected to the end of the lead screw and located inside the mounting box. Moving rods are slidably connected to both sides of the mounting box. The moving rods are inclined on the side closer to each other and fit against the side wall of the conical block. Clamping plates that fit against the outer wall of the upper screws are fixedly connected to the side of the moving rods furthest away from each other. During installation and fixing, rotating the lead screw causes the conical block to move.

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] likeFigures 1-5 The mobile power supply hanging frame shown includes a slide rail frame 1 and a movable component equidistantly arranged on the slide rail frame 1. An upper pressing plate 2 is provided below the movable component, and an upper arc plate 4 is provided below the upper pressing plate 2. A pair of upper screws 3 are provided through the top of the upper pressing plate 2, and the bottom of the upper screws 3 passes through the upper arc plate 4 and is threadedly connected to an upper nut 5. During installation, the cable is passed between the multiple upper pressing plates 2 and the upper arc plate 4 respectively, and then the upper nut 5 is rotated to connect with the upper screws 3. This causes the upper arc plate 4 to move upward and press the cable between the upper arc plate 4 and the upper pressing plate 2, thereby achieving rapid fixing of the cable. An expansion mechanism is provided below the upper arc plate 4. The expansion mechanism includes a lower arc plate 6, a mounting box 7, and a lower extrusion plate 8. The lower extrusion plate 8 is located at the bottom of the mounting box 7. A pair of bolts 13 are threaded through the top of the lower extrusion plate 8, and the bottom of the bolts 13 passes through the lower arc plate 6 and is threadedly connected to a lower nut 14. The mounting box 7 is located between the upper screws 3, and a lead screw 9 is threaded through the side wall of the mounting box 7. A conical block 10 is rotatably connected to the end of the lead screw 9 and located inside the mounting box 7. Moving rods 11 are slidably connected to both sides of the mounting box 7. The moving rods 11 are inclined on the side closer to each other and fit against the side wall of the conical block 10. The moving rods 11 are fixedly connected to the side away from each other and fit against the outer wall of the upper screw 3. When adding electrical components to a mobile device requires additional cables, first place the mounting box 7 between the upper screws 3. Then, rotate the screw 9 to move it inward, which pushes the conical block 10 to slide and press the moving rod 11 to both sides. This causes the clamping plate 12 to move to both sides and press the outer wall of the upper screw 3, pressing the mounting box 7 between the upper screws 3. At the same time, the limit nut 19 can be screwed into the outer wall of the upper screw 3 to abut against the bottom of the clamping plate 12. Finally, pass the added cable through the lower extrusion plates 8 and the lower arc plate 6 respectively, and then rotate the lower nut 14 to connect with the bolt 13. This causes the lower arc plate 6 to move upward and press the cable between the lower arc plate 6 and the lower extrusion plate 8, thus achieving quick fixing of the added cable without the need for repeated disassembly and replacement of all the cable hanging components.

[0023] like Figure 5As shown, a threaded rod 15 is fixedly connected to the top of the lower extrusion plate 8. A threaded groove 16 adapted to the threaded rod 15 is opened at the bottom of the mounting box 7. The threaded rod 15 is threadedly connected in the threaded groove 16. With the setting of the threaded rod 15 and the threaded groove 16, the lower arc plate 6 and the lower extrusion plate 8 adapted to the cable size can be replaced. A guide block 17 is fixedly connected to the top of the conical block 10. A guide groove 18 is opened at the top of the mounting box 7 and at the position corresponding to the guide block 17. The guide block 17 is slidably connected to the inside of the guide groove 18. During the process of rotating the screw 9 to move the conical block 10, the guide block 17 can be driven to slide in the guide groove 18, thereby guiding the sliding of the conical block 10 and preventing the conical block 10 from rotating with the screw 9, which would affect the movement of the moving rod 11 to move the clamping plate 12 to clamp the upper screw 3. Rubber pads 29 are fixedly connected to the bottom of the upper extrusion plate 2 and the lower extrusion plate 8, which can effectively increase the clamping stability of the cable.

[0024] like Figure 3 As shown, in order to further improve the stability of the expansion mechanism connection, the bottom of the upper screw 3 is threaded with a limit nut 19. The top of the limit nut 19 abuts against the bottom of the clamping plate 12. The bottom of the moving rod 11, located outside the limit nut 19, is fixedly connected with a limit plate 20. The side wall of the limit plate 20 abuts against the outer wall of the limit nut 19. First, the limit nut 19 can limit the bottom of the clamping plate 12, preventing the clamping plate 12 from gradually sliding down during use. Second, when the clamping plate 12 is clamped and supported by the upper screw 3, it will drive the limit plate 20 to fit against the side wall plane of the limit nut 19, thereby limiting the rotation of the limit nut 19 and preventing the limit nut 19 from affecting the limiting effect on the clamping plate 12.

[0025] like Figure 1 , Figure 2As shown, the moving assembly includes a support frame 21 and pulleys 32. A pair of support rods 22 are fixedly connected to the bottom of the support frame 21. The tops of the upper screws 3 are all fixedly connected to the bottoms of the support rods 22. The bottoms of the support rods 22 abut against the tops of the upper extrusion plate 2. Connecting rods 23 are provided on the inclined surfaces of the support frame 21. The pulleys 32 are rotatably connected to the ends of the connecting rods 23 and rollingly connected to the tops of the slide rail frame 1. When the moving device moves, it pulls the pulleys 32 on the moving assembly to move on the slide rail frame 1. This enables mobile power supply to mobile devices. The bottom of each connecting rod 23 is fixedly connected to a positioning screw 24, and the bottom of the positioning screw 24 is threaded through the inclined surface of the support frame 21 and connected to a positioning nut 25. By unscrewing the positioning nut 25 out of the outer wall of the positioning screw 24, the position of the connecting rod 23 is released, and the connecting rod 23 and the positioning screw 24 can be pulled out to remove the pulley 32. The pulley 32 can be replaced separately without removing the entire moving assembly to replace the pulley 32, thus improving the convenience of the device. Each support frame 21 has a wire guide frame 26 fixedly connected to its bottom center. The wire guide frame 26 allows steel wire ropes to pass through multiple wire guide frames 26 during use, with both ends of the wire rope fixed to the wire guide frames 26 at both ends. This limits the sliding distance of the moving component, preventing excessive movement and damage to the cable. Both sides of the support frame 21 are fixedly connected to collision rods 27, with rubber blocks 28 fixedly connected to the opposite side of each collision rod 27. The collision rods 27 and rubber blocks 28 effectively prevent the moving component from colliding with the cable, improving the device's protective performance. The top of the slide rail frame 1 is fixedly connected to a rain shield 31 via several top rods 30, which protects the pulleys 32 on the moving component from rain, preventing rainwater from entering the bearings of the pulleys 32 when the cable hanger is used in an external environment, thus affecting the device's service life.
