Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically a novel trough-type cable tray. Background Technology
[0002] A trough-type cable tray is a cable laying device mainly used to protect and manage various types of cables (such as power cables, control cables, communication cables, etc.). It consists of components such as trough, cover plate, and bracket. It can effectively isolate dust, water vapor, corrosive substances and external mechanical damage. It is suitable for environments with a lot of dust, humidity, corrosiveness or electromagnetic interference that need to be shielded. During installation, it can be fixed along the wall, ceiling or bracket to achieve neat arrangement of cables and facilitate later inspection and maintenance. The existing three-channel trough-type cable trays have obvious shortcomings. The opening angles are mostly fixed, making it difficult to adapt to specific angle installation environments such as building corners or inclined connections between different floors. Either special angle cable trays need to be customized, increasing costs and construction time, or cable trays need to be spliced or forcibly bent to adapt, which can easily damage the cable tray structure and internal cables, reducing the stability of the overall cabling system. However, although some designs incorporate a rotatable structure at the middle port to address the angle adaptation issue, in actual operation, the cables are in close contact with the inner wall of the cable tray at bends, and there is a lack of effective friction-reducing and guiding structures. When pulling the cables, the friction between the cables and the cable tray is high, making it difficult to move them flexibly. This increases the difficulty of operation for construction workers, prolongs wiring time, and reduces work efficiency. Therefore, a new type of trough-type cable tray is proposed to address the above problems. Utility Model Content

A support member is fixed to the bottom of the outer side of the tray body. A movable cable tray is rotatably connected to the middle of the inner side of the tray body via a connecting screw. A flexible connection mechanism is installed between the movable cable tray and the tray body. A rotating groove for cooperating with the rotation of the movable cable tray is opened on one side of the tray body. The flexible connection mechanism includes a flexible rod, with rigid connecting rods sleeved at both ends of the flexible rod. A flexible plate is fixed below the flexible rod.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A novel trough-type cable tray includes a tray body 1, a support member 2 fixed to the bottom of the outer side of the tray body 1, and a movable cable tray 3 rotatably connected to the middle of the inner side of the tray body 1 via a connecting screw. A flexible connection mechanism 4 is installed between the movable cable tray 3 and the tray body 1. A rotating groove 5 is provided on one side of the tray body 1 to cooperate with the rotation of the movable cable tray 3. The flexible connection mechanism 4 includes a flexible rod 41, with rigid connecting rods 42 sleeved at both ends of the flexible rod 41. A flexible plate 43 is fixed below the flexible rod 41, and the inner side of the flexible plate 43... A cable clamp 44 arranged in an arc shape is fixedly installed. The cable clamp 44 includes a clamping body 441. A cable limiting cavity 442 is opened on the outer side of the clamping body 441. Two ball placement cavities 443 and a lubricating oil storage cavity 444 are opened on the inner side of the clamping body 441. Balls 445 are embedded in the inner side of the ball placement cavity 443. A connecting rib 446 is fixed at the rear end of the clamping body 441. A rubber protective layer 447 arranged in a linear pattern is fixed on the outer side of the connecting rib 446. The connecting rib 446 is fixedly connected to the flexible plate 43.
[0017] During installation, the staff first uses the connecting screws to rotate and connect the movable cable tray 3 to the main body 1 of the cable tray. According to the angle requirements of the installation environment, the movable cable tray 3 is rotated and the locking nut is tightened to fix it. Through bolts, mounting holes 6 and connecting holes 45, the rigid connecting rod 42 of the flexible connection mechanism 4 is fixed to the top of the main body 1 of the cable tray and the movable cable tray 3. Lubricating oil is filled into the lubricating oil storage cavity 444. The cable is inserted into the cable limiting cavity 442. During the wiring process, when the cable is pulled, the ball 445 rotates and carries the lubricating oil to reduce friction. The flexible rod 41 and the flexible plate 43 deform with the angle of the cable tray to ensure smooth cable movement. The rubber protective layer 447 protects the connecting rib 446. The support 2 provides support and protection to complete the efficient wiring operation. As a further implementation of this solution, the support member 2 is located at the center of the bottom outer side of the cable tray body 1. The outer side of the support member 2 has an arc-shaped structure. The outer side of the support member 2 rotates and engages with the inner side of the movable cable tray 3. The center of the support member 2 and the center of the movable cable tray 3 are located on the same central axis. This design ensures that the movable cable tray 3 is always in close contact with the support member 2 when it rotates, which not only ensures smooth rotation, but also disperses the force through the arc-shaped support surface, enhancing the overall structural stability. At the same time, the arc-shaped outer side can better block dust and debris from entering from the bottom gap, improving the protection effect on the internal cables. As a further implementation of this solution, the movable cable tray 3 is located between the two rotating slots 5. The upper surface of the movable cable tray 3 is at the same horizontal height as the upper surface of the cable tray body 1. The flush upper and lower surfaces make the installation of the flexible connection mechanism 4 more level, avoid uneven force on the connecting parts due to height difference, and at the same time ensure smooth transition when laying cables and reduce wear of cables at the turning points. As a further implementation of this solution, the rigid connecting rod 42 extends to the top of the inner side of the cable tray body 1. The top of the cable tray body 1 is provided with mounting holes 6 for fitting the connecting holes 45. The number of mounting holes 6 is the same as the number of connecting holes 45. The mounting holes 6 and the connecting holes 45 are connected by bolts. This connection method makes the rigid connecting rod 42 more firmly fixed to the cable tray body 1 and the movable cable tray 3, and improves the overall stability of the flexible connection mechanism 4. As a further implementation of this solution, the inner side of the flexible rod 41 is provided with an arc-shaped array of deformation enhancement grooves 46. The inner side of the deformation enhancement grooves 46 has an arc-shaped structure. The arc-shaped deformation enhancement grooves 46 can provide more deformation space for the flexible rod 41 when it deforms with the angle of the cable tray, reduce the internal stress during deformation, and prevent the flexible rod 41 from being damaged due to repeated deformation. As a further implementation of this solution, the front end of the clamping body 441 is spherical, the inner side of the cable limiting cavity 442 is spherical, the cable limiting cavity 442 is connected to the ball placement cavity 443, and the lubricating oil storage cavity 444 is located between the two ball placement cavities 443. The interconnection design allows the ball 445 to fully contact the cable, and the position of the lubricating oil storage cavity 444 facilitates the transfer of lubricating oil grease to the cable surface through the ball 445, continuously reducing friction when the cable is pulled and ensuring smooth wiring. As a further implementation of this solution, the outer side of the rubber protective layer 447 has a circular structure, and the center of the rubber protective layer 447 and the center of the clamping body 441 are located on the same central axis. The rubber protective layer 447 is used to enhance the protection effect on the connecting rib 446.
[0018] Workflow: The movable cable tray 3 is rotatably connected to the main cable tray 1 via connecting screws. When angle adjustment is required, loosen the connecting screws, tighten the locking nut, rotate the movable cable tray 3 to the appropriate angle, and then tighten the nut to the limit position. Support component 2 provides support for the movable cable tray 3, preventing breakage and blocking foreign objects from entering from below. The rigid connecting rod 42, through the mounting hole 6, connecting hole 45, and bolts, firmly fixes the flexible connecting mechanism 4 to the top of the main cable tray 1 and the movable cable tray 3. This multi-fixing structure ensures that the flexible connecting mechanism 4 will not loosen or fall off during long-term use, providing continuous and stable support for the cables. Furthermore, the bolt connection method facilitates disassembly, adjustment, or replacement according to actual needs, enhancing the maintainability and reusability of the cable tray. The flexible rod 41 has excellent deformation capability, and the deformation enhancement groove 46 on its inner side further improves the bending performance. It can flexibly deform with the change of cable tray angle and always keep in close contact with the cable tray. This characteristic allows the flexible connection mechanism 4 to perfectly adapt to the wiring requirements of different angles, avoid the pulling force on the cable due to the change of cable tray angle, and effectively protect the internal structure of the cable. During the deformation process, the flexible plate 43 will simultaneously adjust the opening and closing angle of the adjacent cable clamps 44 to ensure that each cable clamp 44 can maintain good contact with the cable. This avoids the cable from shaking and rubbing due to loosening, and also prevents the cable from being damaged due to excessive compression, thus achieving precise protection of the cable. After the cable passes through the adjacent cable limiting cavities 442, the clamping body 441 effectively limits the cable, preventing it from shifting or tangling due to external forces such as vibration and wind during operation. This ensures a neat and orderly cable layout, facilitating later inspection and maintenance. The balls 445 in the ball placement cavity 443 are in close contact with the cable surface. When the cable is pulled and laid, the balls 445 rotate flexibly with the cable, evenly distributing the pre-filled lubricating grease in the lubricating oil storage cavity 444 to the cable surface, forming a lubricating protective film. This design significantly reduces the friction between the cable and the clamping body 441, making the cable move more smoothly at bends. This not only reduces the pulling force of construction personnel and lowers labor intensity, but also avoids problems such as cable sheath wear and exposed internal copper core caused by excessive friction, extending the cable's service life.
