Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a multi-layer partitioned cable tray. Background Technology

[0002] Cable trays serve as a crucial carrier for laying power and communication cables, and their structural design directly impacts the efficiency and safety of cable management. Currently, common cable trays on the market mainly adopt structures such as trough type, tray type, ladder type, and mesh type, and are installed using components such as supports and brackets.

[0003] However, traditional cable trays often employ a one-piece assembly cavity design, lacking a flexible internal partitioning mechanism, which prevents the effective layering of cables of different voltage levels or uses. This limitation not only increases the risk of cable crosstalk interference but also makes subsequent inspection and maintenance extremely inconvenient, especially in complex cabling scenarios, where maintenance personnel struggle to quickly locate and separate specific cables, significantly reducing work efficiency. Therefore, a multi-layer partitioned cable tray design is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layered, partitioned cable tray to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer partitioned cable tray, comprising a cable tray body and a cover plate covering the opening of the cable tray body, wherein support plates are symmetrically welded to the inner wall of the cable tray body, and positioning posts are vertically installed on the surface of the support plates;

[0006] The cable tray body has a partition inserted inside. The surface of the partition has symmetrical positioning holes. Both ends of the partition have clearance grooves. The clearance grooves of the partition are rotatably connected to guide rollers via shafts. Both ends of the guide rollers are fixedly connected to limit rings.

[0007] Preferably, the surface of the partition is provided with weight-reducing holes at equal intervals, and the partition extends to the two open ends of the cable tray body.
