[0022] 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.

[0023] Please see Figure 1-5 This utility model discloses a combined cable tray structure, including a hoisting structure 1, a cable tray device 2 movably connected to the inner side of the hoisting structure 1, and a cable placement structure 3 provided on the inner side of the cable tray device 2.

[0024] The hoisting structure 1 includes a suspended steel bar 101. The side end of the suspended steel bar 101 is connected to the ceiling or wall by welding. The surface of the suspended steel bar 101 is provided with a connecting corner piece 102. The bottom end of the connecting corner piece 102 is provided with two fitting steel pieces 104 through a connecting hanging ring 103. The two opposing fitting steel pieces 104 are connected to each other through a hinge shaft 105. The two fitting steel pieces 104 on the same side are connected to each other through a locking rod 106.

[0025] The surface of the steel fitting 104 is provided with anti-slip texture. The anti-slip texture increases the friction between the steel fitting 104 and the cable tray device 2, so that the cable tray device 2 can be placed more stably on the inner side of the steel fitting 104, and avoids the cable tray device 2 from slipping during use.

[0026] By setting up the hoisting structure 1, the angle of the two opposing mating steel parts 104 can be adjusted using the hinge shaft 105. In conjunction with the locking rod 106, the two mating steel parts 104 on the same side can be synchronously limited, so that the four mating steel parts 104 can be quickly disassembled and assembled with the cable tray device 2 without the need to use bolts to reinforce the cable tray device 2. This improves the convenience of the staff when replacing the cable tray, further improves the work efficiency, and avoids the situation where bolts are prone to loosening after long-term use, thus ensuring the stability of the cable tray.

[0027] The cable tray device 2 includes a top cover 201 and a base 202, which are movably connected by a connecting fastener 203. The top cover 201 and the base 202 are located on the inner side of the steel component 104.

[0028] Specifically, the surface of the suspended reinforcing bar 101 and the top of the connecting corner piece 102 are provided with snap-fit ​​holes, and the top of the connecting corner piece 102 is movably snapped into the snap-fit ​​hole of the suspended reinforcing bar 101 through a snap-fit ​​pin.

[0029] In this embodiment, the connecting corner piece 102 increases the connection stability between the suspended reinforcing bar 101 and the fitting steel piece 104, making the overall hoisting structure 1 more robust. Simultaneously, the top of the connecting corner piece 102 is movably engaged with the engaging hole of the suspended reinforcing bar 101 via a snap-fit ​​pin. This engaging method facilitates disassembly and installation, further improving work efficiency.

[0030] Specifically, the surface of the base 202 is provided with heat dissipation vents 204, which are located on both sides of the base 202.

[0031] In this embodiment, the heat dissipation vent 204 can effectively dissipate the heat generated inside the cable tray device 2, preventing the normal use of the cable from being affected by excessive temperature.

[0032] Specifically, the cable placement structure 3 includes a placement plate 301, which is fixedly connected to the interior of the base 202. A cable limiting device 303 is provided at the front end of the placement plate 301, and a cable guide ring 304 is provided at the end of the placement plate 301.

[0033] In this embodiment, the design of the cable limiting device 303 and the cable guide ring 304 not only facilitates the laying of cables and enables the correct positioning of cables, but also prevents the wiring inside the cable tray device 2 from becoming chaotic and disorderly, thus ensuring the safety and stability of the cables inside the cable tray device 2.

[0034] Specifically, both the cable limiting device 303 and the cable guide ring 304 are equipped with connecting blocks 302 at their bottom ends, and the connecting blocks 302 are movably connected to the end of the placement plate 301 via connecting pins.

[0035] In this embodiment, the design of this movable connection method allows the positions of the cable limiting device 303 and the cable guide ring 304 to be flexibly adjusted according to the actual cable routing and needs, further improving the adaptability and flexibility of the cable tray. Furthermore, the connecting block 302 and the connecting pin are both made of high-strength materials, ensuring the stability and durability of the connection and effectively preventing cable detachment or damage due to loose connections.

[0036] Specifically, the cable limiting device 303 includes a connecting ring 305, a fixed half-ring 306 and a movable half-ring 307 are installed on the front side of the connecting ring 305, and the fixed half-ring 306 and the movable half-ring 307 are movably engaged by a limiting pin 308.

[0037] In this embodiment, the cable limiting device 303, through the cooperation of the fixed half-ring 306 and the movable half-ring 307, can effectively fix the cable and prevent the cable from shaking or falling out inside the cable tray device 2. The cable guide ring 304 facilitates cable lead-out and connection, improving the practicality and flexibility of the cable tray.

[0038] When in use, the staff first welds the hoisting structure 1 to the side of the ceiling or wall through the suspension steel bar 101, then limits the two fitting steel parts 104 on the same side through the locking rod 106, and then inserts the cable tray device 2 between the four fitting steel parts 104 so that the cable tray device 2 can be placed more stably inside the hoisting structure 1.

[0039] The cable is then passed through the cable placement structure 3, so that the cable is pre-passed through the cable limiting device 303 and moves forward along the path of the placement plate 301 until the end of the cable passes through the cable guide ring 304, so as to ensure that the cable is neatly arranged inside the cable tray device 2, without crossing or squeezing.

[0040] In addition, when the cable tray needs maintenance or replacement, the staff can easily remove the cable tray device 2 from the inside of the hoisting structure 1 by simply loosening the locking rod 106, without the need for disassembly using tools, which improves work efficiency.

[0041] In summary, this modular cable tray structure, through the installation of the hoisting structure 1, allows for angle adjustment of two opposing mating steel parts 104 using the hinge shaft 105. Furthermore, the locking rod 106 synchronously limits the movement of the two mating steel parts 104 on the same side, enabling the four mating steel parts 104 to be quickly assembled and disassembled from the cable tray device 2 without the need for bolts to reinforce the device. This improves the convenience of cable tray replacement for workers, further enhancing work efficiency. Simultaneously, it avoids the loosening of bolts over time, ensuring the stability of the cable tray.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
