Description

Technical Field

[0001] The present application relates to the field of weak-current bridges, and in particular to an adjustable weak-current bridge. Background Art

[0002] The weak-current cable tray has the advantages of compact and reasonable structure, strong carrying capacity, flexible configuration, convenient installation, and complete specifications. It is widely used in intelligent weak-current system projects. The weak-current cable tray makes the laying of cable lines and the network wiring of high-rise buildings neat, beautiful, and standardized. It also realizes standardization, serialization, and generalization in engineering design, providing a new way to beautify the environment and safe production. The cable tray has the characteristics of wide application, high strength, light structure, low cost, simple construction, flexible wiring, safety standards, and beautiful appearance, which brings convenience to technical transformation, cable expansion, maintenance and repair. However, because there are many types of weak-current lines now, and because of the large-scale use of optical cables, the 5-category network cable, 6-category network cable, skin-line optical cable, and 485 signal cable in the bridge are all laid in one space, causing various types of lines to be entangled together, which greatly increases the workload of weak-current construction and later maintenance.

[0003] The patent with application number 202123102087.8 discloses an adjustable weak-current bridge based on the integrated wiring of weak-current lines. The weak-current bridge includes a bridge body, a wire trough is inside the bridge body, and a movable partition is arranged in the wire trough. The root of the movable partition is installed on the bottom plate of the bridge body, and can move left and right on the bottom plate to separate the wire trough into two left and right troughs, which can divide the internal space of the bridge, and the size of the divided space inside can be adjusted, so that different lines can be classified.

[0004] The above technical solution utilizes a sliding movable partition to adjust the wiring space within the weak point bridge, but due to the lack of positioning of the movable partition, the movable partition is easily shaken or squeezed by the cable and misaligned after adjustment, resulting in poor stability in adjusting the wiring space inside the weak point bridge.
