[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5A novel modular energy-saving metal cable tray includes a first cable tray 1, a second cable tray 2, a connecting seat 3, a fastening device, and a limiting device. The connecting seat 3 has an assembly groove 4 at its top. Two sets of fastening plates 5 are installed in the assembly groove 4 via the fastening device. The first cable tray 1 and the second cable tray 2 are fastened together by the two sets of fastening plates 5. The limiting device is installed at the ends of the two sets of fastening plates 5 that are close to each other. The inner sidewalls of the first cable tray 1 and the second cable tray 2 are limited and connected by the limiting device. In this embodiment, the first cable tray 1 and the second cable tray 2 are made of metal. In use, the first cable tray 1 and the second cable tray 2 are aligned and placed between the two sets of fastening plates 5, and then fastened together using the fastening device to clamp and fix the first cable tray 1 and the second cable tray 2. During this process, it is necessary to ensure that the two cable trays are securely connected. The cable trays are accurately aligned without noticeable gaps or misalignments and are centered. Then, limiting devices are used on the inner walls of the first cable tray 1 and the second cable tray 2 to limit the connection. These limiting devices help to further stabilize the connection between the first cable tray 1 and the second cable tray 2, while restricting their movement within a certain range to prevent positional deviation caused by external factors, thereby enhancing the stability of the overall structure and ensuring the safety and reliability of the cable arrangement. Due to the modular design, this cable tray system can be quickly assembled and disassembled, greatly improving construction efficiency and reducing on-site working time. The design of multi-point limiting devices not only enhances the connection strength between the first cable tray 1 and the second cable tray 2, but also effectively prevents displacement caused by vibration or other external forces, improving the safety performance of the entire system. It also allows for the selection of the connected cable tray length as needed.

[0027] Preferably, in this embodiment, the fastening device includes a rectangular groove 6, a bidirectional screw 7, a drive shaft 8, a slider 9, and a knob 10. The rectangular groove 6 is provided at the top of the assembly groove 4. The bidirectional screw 7 is rotatably installed in the rectangular groove 6. The slider 9 is installed at both ends of the bidirectional screw 7. The top wall of the slider 9 is fixedly connected to the bottom wall of the corresponding fastening plate 5. One end of the bidirectional screw 7 passes through the side wall of the connecting seat 3 and is equipped with the drive shaft 8. The knob 10 is installed at the end of the drive shaft 8. First, ensure that the first cable tray 1 and the second cable tray 2 are correctly placed on both sides of the assembly groove 4 of the connecting seat 3 and that the edges of the first cable tray 1 and the second cable tray 2 are aligned. The operator can then use the knob 10 to... Rotate the knob 10 mounted on the end of the drive shaft 8 to rotate the bidirectional screw 7. Due to the design of the bidirectional screw 7, when it rotates, it will cause the sliders 9 at both ends to move towards or away from each other, depending on the direction of rotation. As the bidirectional screw 7 rotates, the sliders 9 move along the rectangular groove 6, causing the fastening plates 5 to move closer or further away from each other. In order to achieve the fastening effect, the knob 10 needs to be rotated in the direction that brings the two fastening plates 5 closer to each other until the fastening plates 5 firmly clamp the first bridge 1 and the second bridge 2. After the required degree of fastening is achieved, stop rotating the knob 10. At this time, the first bridge 1 and the second bridge 2 are tightly connected together by the fastening device to form an integral structure, realizing the initial clamping connection of the first bridge 1 and the second bridge 2.

[0028] Preferably, in this embodiment, a chuck 11 is fixedly installed on the outer wall of the drive shaft 8, a support seat 12 is installed on the side wall of the connecting seat 3, and the locking block 13 is rotatably installed on the side wall of the support seat 12. The chuck 11 and the locking block 13 are engaged and connected. The engagement of the chuck 11 and the locking block 13 can effectively lock the position of the drive shaft 8 and prevent the drive shaft 8 from rotating accidentally due to external forces such as vibration or accidental contact. This ensures the stability of the fastening device. In particular, after the cable tray is fastened, it can prevent any unnecessary adjustments. By limiting the unexpected rotation of the drive shaft 8, it reduces the safety hazards caused by the accidental loosening of the drive shaft 8, such as the instability of the cable tray structure caused by the loosening of fasteners, thereby improving the safety of the entire system. When adjustment is required, the locking block 13 can be manually disengaged from the chuck 11, and then the position of the bidirectional screw 7 can be precisely adjusted by the knob 10. This design allows users to easily make adjustments when needed, while maintaining a stable state when no adjustment is required.

[0029] Preferably, in this embodiment, the outer wall of the knob 10 is provided with anti-slip texture. The anti-slip texture can increase the friction between the fingers and the knob 10, so that the operator can hold the knob 10 firmly even when wearing gloves or with wet hands, which greatly improves the convenience and reliability of operation.

[0030] Preferably, in this embodiment, the connecting seat 3 has a U-shaped design. The U-shaped design can provide stronger structural support. Compared with the flat plate design, the U-shaped cross-section increases the material distribution area, which enhances the bending and torsional resistance without adding extra material.

[0031] Preferably, in this embodiment, the limiting device includes a movable groove 14, a movable block 15, a guide groove 16, a guide block 17, a spring 18, a through groove 19, a limiting plate 20, and a limiting groove 21. The movable groove 14 is formed on the side wall of the fastening plate 5 away from the connecting seat 3. The movable block 15 is slidably installed in the movable groove 14. Guide grooves 16 are formed at both ends of the movable groove 14. Guide blocks 17 are installed at both ends of the movable block 15. The guide blocks 17 and the guide grooves 16 are slidably connected. A spring 18 is installed in the guide groove 16 to support the slider 9. The spring 18 supports the movable block 15, and the limiting plate 20 is rotatably mounted on the outer surface of the movable block 15. Two sets of through slots 19 are symmetrically opened at both the front and rear ends of the first cable tray 1 and the second cable tray 2. A limiting slot 21 is vertically opened on the inner sidewall of each through slot 19. The limiting slot 21 and the limiting plate 20 are adapted to each other. When not connected, the movable block 15 is located within the movable slot 14, and the limiting plate 20 is in a retracted state, i.e., parallel to the movable block 15. The spring 18 is in a supporting state, limiting the limiting plate 20 to the outer wall of the movable slot 14. When the first cable tray 1 and the second cable tray 2 are connected by a fastening device... After the frame 2 is connected, manually pull the limiting plate 20. The limiting plate 20 causes the movable block 15 to slide in the movable groove 14. When the movable block 15 slides, it causes the guide block 17 to slide in the guide groove 16 and compress the spring 18. After the limiting plate 20 passes through the through groove 19 on the corresponding first bridge frame 1 or second bridge frame 2, rotate the limiting plate 20 180 degrees so that the limiting plate 20 is parallel to the limiting groove 21. Then release the limiting plate 20. The spring 18 in the guide groove 16 will then extend, causing the guide block 17 to slide inward in the guide groove 16 and causing the movable block 15 to slide inward. The limiting plate 20 moves inward and then enters the limiting groove 21. Once the limiting plate 20 is fully engaged in the limiting groove 21, the entire system completes the limiting lock. The two sets of limiting devices on each set of fastening plates 5 are connected in sequence according to the above steps. At this time, the first cable tray 1 and the second cable tray 2 are tightly connected to the corresponding fastening plates 5 through the limiting devices, forming a stable overall structure. The design of the limiting device ensures a firm connection between the first cable tray 1 and the second cable tray 2, effectively preventing loosening or displacement caused by external forces, and improving the safety and reliability of the overall structure.

[0032] Preferably, in this embodiment, a guide rod 22 is fixedly installed in the guide groove 16. The guide rod 22 passes through the spring 18 and is slidably connected to the guide block 17. The guide rod 22 ensures that the guide block 17 moves accurately along a predetermined straight path, reducing the offset or jamming that may occur due to relying solely on the guide groove 16. When the spring 18 is used on the guide rod 22, it can extend and retract on a fixed axis instead of floating freely. This helps to maintain the elasticity and restoring force of the spring 18, ensuring that it maintains a consistent rebound effect over a long period of time, and improving the working efficiency and reliability of the spring 18.

[0033] Preferably, in this embodiment, a handle 23 is installed on the outer surface of the limiting plate 20. After the handle 23 is installed, the operator can rotate or move the limiting plate 20 more conveniently by holding the handle 23. This is particularly useful when the position of the limiting plate 20 needs to be precisely controlled, making the operation more intuitive and easier to perform.
