Description

Technical Field

[0001] This application relates to the technical field of cable trays, and in particular to a cable tray cable wiring device. Background Technology

[0002] With the rapid development of people's living standards, cable trays are being installed in more and more buildings. The main function of cable trays is to connect and route cables, facilitate the routing of electrical components in buildings, reduce the space occupied by cables, and make it easier for people to connect and manage cables.

[0003] Existing cable trays generally lack cable management adjustment capabilities, and cables may become tangled and intertwined during installation, making maintenance difficult. Most existing devices also fail to allow for quick installation of the cover plates, requiring operators to secure them with bolts, further complicating installation and removal. Therefore, to address these issues, this application provides a cable tray cable routing device. Utility Model Content

[0004] To address the issues of lacking wiring adjustment capabilities and the inability to quickly install the cover plate, this application provides a cable tray cable wiring device.

[0005] This application provides a cable tray cable wiring device, including a cable tray box. Connecting boxes are fixedly connected to both sides of the inside of the cable tray box. A bidirectional threaded rod is rotatably connected to one side of the inside of each connecting box. Limiting rods are fixedly connected to both sides of the inside of the connecting box corresponding to the bidirectional threaded rods. Moving plates are threadedly connected to both sides of the outer wall of each bidirectional threaded rod. A connecting rod assembly is arranged inside the connecting box via two of the moving plates. An opening is provided at the center of the upper surface of the connecting box. Several connecting plates are slidably connected to the upper surface of the connecting box via the connecting rod assembly.

[0006] Preferably, sliders are fixedly connected to both sides of the upper surface of the connecting box, and several limiting blocks are slidably connected to the upper surface of the connecting box through several connecting plates and two sliders.

[0007] Preferably, the lower surface of the limiting block is provided with a sliding groove on the side corresponding to the slider, and the side surface of the cable tray box is rotatably connected to a handle through the bidirectional threaded rod.

[0008] Preferably, cable grooves are provided on both sides of the outer wall of the limiting block.

[0009] Preferably, the cable tray box has slots on both sides of its side surface, and a cover is provided on the upper surface of the cable tray box through several slots. The inner wall of the cover is fixedly connected to a locking block on the side corresponding to the slot.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. By rotating the handle, the bidirectional threaded rod rotates inside the connector box, causing the connecting plates on both sides to move towards each other. Several connecting plates connect to the connecting rod assembly, causing the assembly to retract. The connecting rod in the middle of the assembly passes through an opening and connects to several connecting plates. These connecting plates then connect to limiting blocks, causing the limiting blocks to retract towards the center, thus clamping the cables. Compared to existing technologies, this method allows for rapid, zoned cable routing, preventing the mixing and accumulation of various cable types when using the cable tray box.

[0012] 2. By aligning the locking block with the notch in the slot, pressing down the cover, and finally pulling the cover backward, the locking block enters the slot, thereby connecting the cable tray box and the cover. Compared with existing technologies, this method facilitates quick installation and disassembly of the cable tray box and the cover. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1

[0020] Please see Figures 1-4 This utility model provides a technical solution for a cable tray cable wiring device:

[0021] A cable tray cable wiring device, Figures 1-4 The system includes a cable tray box 1. Connecting boxes 5 are fixedly connected to both sides of the cable tray box 1. A bidirectional threaded rod 12 is rotatably connected to one side of each connecting box 5. The bidirectional threaded rod 12 is installed inside the connecting box 5 via a connector. Limiting rods 14 are fixedly connected to both sides of the bidirectional threaded rod 12 inside the connecting box 5. Moving plates 13 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 12. The helix angle of the outer wall of the bidirectional threaded rod 12 is set to 20 degrees. The bidirectional threaded rod 12 and the moving plates 13 are threadedly connected, and the thread angle of the bidirectional threaded rod 12 is less than the equivalent friction angle of the helical pair formed by the bidirectional threaded rod 12 and the moving plates 13, forming a self-locking mechanism to prevent movement due to external factors. By installing two limiting rods 14 on both sides of the outer wall of the moving plates 13, the two limiting rods 14 restrict the movement direction of the moving plates 13, and the moving plates 13 can slide on the outer wall of the limiting rods 14. The rotation of the bidirectional threaded rod 12 drives the two moving plates 13 to move towards or away from each other. Inside the connecting box 5, a connecting rod assembly 15 is provided through two movable plates 13. The two ends of the connecting rod assembly 15 are connected to the movable plates 13 respectively. The bidirectional threaded rod 12 drives the two movable plates 13 to move towards or away from each other, thereby causing the connecting rod assembly 15 to contract or extend. An opening 10 is provided at the center of the upper surface of the connecting box 5. The connecting rod of the connecting rod assembly 15 extends out through the opening 10 at the top of the connecting box 5. Several connecting plates 11 are slidably connected to the upper surface of the connecting box 5 through the connecting rod assembly 15. The connection plates 11 are connected to the connecting rod assembly 15, so that the bidirectional threaded rod 12 rotates and drives the two movable plates 13 to move towards or away from each other, thereby causing the connecting rod assembly 15 to contract or extend. The connecting plate 11 at the center position does not move, thereby causing the several connecting plates 11 to contract or expand towards the center of the top of the connecting box 5, achieving the effect of facilitating the contraction or expansion of the several connecting plates 11.

[0022] Furthermore, sliders 9 are fixedly connected to both sides of the upper surface of the connection box 5. Several limiting blocks 3 are slidably connected to the upper surface of the connection box 5 through several connecting plates 11 and two sliders 9. The sliders 9 are installed on both sides of the top of the connection box 5. The connection between the several connecting plates 11 and the several limiting blocks 3 is achieved. When the connecting rod assembly 15 contracts or expands, it drives the several connecting plates 11 to contract towards the center position of the top of the connection box 5, and then drives the several limiting blocks 3 to contract towards the center position. This allows the several limiting blocks 3 to clamp the cables, enabling the cables to be laid out in sections for quick wiring. This prevents the cable tray box 1 from mixing and piling up when multiple types of cables are arranged, achieving the effect of enabling the cables to be laid out in sections for quick wiring.

[0023] Furthermore, the lower surface of the limiting block 3 is provided with a groove 8 on one side corresponding to the slider 9. The side surface of the cable tray box 1 is rotatably connected to a handle 4 via a bidirectional threaded rod 12. The bidirectional threaded rod 12 is connected to the handle 4, so that rotating the handle 4 drives the bidirectional threaded rod 12 to rotate inside the connecting box 5. The size of the groove 8 at the bottom of the limiting block 3 matches the size of the slider 9, so that the slider 9 and the limiting block 3 match, allowing several limiting blocks 3 to slide on the top of the connecting box 5.

[0024] Furthermore, cable grooves 16 are provided on both sides of the outer wall of the limiting block 3. Through the cable grooves 16 on the outer wall of the limiting block 3, the cables can be quickly routed by dividing them into sections. This makes it easy to install the cables between the limiting blocks 3 through the cable grooves 16, thus achieving the purpose of preventing the cables from mixing and accumulating when they are inserted into the connection box 5.

[0025] Example 2

[0026] Please see Figures 1-4 Furthermore, based on Example 1, the following was obtained:

[0027] Furthermore, slots 7 are provided on both sides of the side surface of the cable tray box 1. The top surface of the cable tray box 1 is provided with a cover 2 through several slots 7. The inner wall of the cover 2 is fixedly connected to a block 6 on one side corresponding to the slot 7. The size of the block 6 matches the size of the slot 7, so that by aligning the block 6 with the notch of the slot 7, pressing down the cover 2, and finally pulling the cover 2 backward, the block 6 enters the slot 7, thereby connecting the cable tray box 1 and the cover 2. This achieves the effect of facilitating the installation and disassembly of the cable tray box 1 and the cover 2.

[0028] The implementation principle of the cable tray cable routing device in this application embodiment is as follows: When the device is in use, firstly, by rotating the handle 4, the bidirectional threaded rod 12 is driven to rotate inside the connecting box 5, so that the bidirectional threaded rod 12 rotates and drives the connecting plates 11 on both sides to move towards each other. Through the connection between several connecting plates 11 and the connecting rod assembly 15, the connecting rod assembly 15 is driven to retract. The connecting rod in the middle of the connecting rod assembly 15 passes through the opening 10 and connects with several connecting plates 11. Through the connection between the connecting plates 11 and the limiting blocks 3, the limiting blocks 3 are driven to retract towards the center position, so that the limiting blocks 3 clamp the cables, thereby enabling the cables to be quickly routed in sections, so that when multiple types of cables are arranged in the cable tray box 1, they will not be mixed and piled up.
