Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to an improved aluminum alloy cable tray. Background Technology

[0002] Aluminum alloy cable trays are characterized by their attractive appearance, simple structure, unique design, high load-bearing capacity, and light weight. After anodizing, aluminum alloy cable trays not only resist corrosion but also electromagnetic interference, especially shielding interference, which is irreplaceable by steel cable trays.

[0003] With the development of intelligent buildings, a single building often contains AC high-voltage systems, low-voltage systems, DC high-voltage systems, and various automation systems, such as building automation systems, office automation systems, and communication automation systems. Therefore, it is necessary to lay various types of cables, including AC high-voltage cables, DC high-voltage cables, and low-voltage cables such as communication cables and control cables.

[0004] Existing aluminum alloy cable trays have a simple structure and contain various types of cables. These cables are prone to tangling during installation, and interference between them can affect the normal operation of the equipment. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an improved aluminum alloy cable tray. This improves upon existing aluminum alloy cable trays, which have a simple structure, house various cables, and are prone to tangling during installation, leading to mutual interference and affecting the normal operation of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved aluminum alloy cable tray includes a cable tray body, which includes a cable tray base plate. A supporting vertical plate is slidably disposed on the top end face of the cable tray base plate. A fixing groove is formed on the top end face of the supporting vertical plate. An internal groove communicating with the fixing groove is formed in the supporting vertical plate. A partition vertical plate extending to the outside of the supporting vertical plate is slidably connected in the internal groove. Positioning rods are symmetrically fixedly connected to the bottom of both sides of the partition vertical plate. Cable tray side plates are symmetrically fixedly connected to both sides of the top end face of the cable tray base plate. An embedding groove is formed on the top of the inner side wall of the cable tray side plate. A partition horizontal plate that can rotatably overlap the fixing groove of the supporting vertical plate is hinged in the embedding groove.

[0008] As a further embodiment of this utility model, hooks are rotatably provided at both ends of the inner wall of one side plate of the cable tray, and a groove is provided on the positioning rod for the hooks to rotate and engage when the vertical plate is displaced to fit against the inner wall of the side plate of the cable tray.

[0009] As a further scheme of the utility model, the bottom end face of the support vertical plate is symmetrically fixedly connected with a limiting block, and the bridge bottom plate top end face is provided with a limiting sliding slot for the displacement of the limiting block.

[0010] As a further scheme of the utility model, the support vertical plate is symmetrically provided with a limiting slot for the up-down displacement of the positioning rod, the limiting slot top end is provided with an internal thread groove, and the internal thread groove is screwed with a fixing member.

[0011] As a further scheme of the utility model, the fixing member comprises a head, one side of the head is fixedly connected with a screw rod in threaded connection with the internal thread groove, and the head is provided with a positioning hole penetrating the screw rod for the insertion of the positioning rod.

[0012] As a further scheme of the utility model, the partition horizontal plate is provided with a first fixing hole for the insertion of the fixing bolt, and the bridge side plate is provided with a second fixing hole for the storage of the partition horizontal plate into the embedded groove and in communication with the first fixing hole.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] When the cable inside the bridge body is not needed to be laid in sections, the support vertical plate and the partition horizontal plate are stored and attached to the inner side wall of the bridge side plate, without affecting the normal laying of the cable, when the cable inside the bridge body is needed to be laid in sections, the support vertical plate and the partition horizontal plate can partition the space inside the bridge body, thereby laying the cables in sections, effectively avoiding the mutual winding of the cables, avoiding the mutual interference between the cables, and ensuring the normal operation of the equipment.
