Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and in particular to a modular quick-installation bracket structure for low-voltage distribution boxes. Background Technology

[0002] Low-voltage distribution boxes assemble switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in enclosed or semi-enclosed metal cabinets according to electrical wiring requirements. During normal operation, circuits can be connected and disconnected using switches. In case of faults or abnormal operation, circuits can be cut off and alarms can be triggered by protective electrical appliances. Various operating parameters can also be displayed through measuring instruments. As the core equipment for power distribution, control, and protection at the end of the power system, low-voltage distribution boxes are widely used in industrial plants, commercial buildings, residential communities, and municipal facilities. Their installation quality and efficiency directly affect the safe and stable operation of the power system and the progress of project construction.

[0003] Traditional mounting brackets rely on manual experience, requiring on-site measurement, steel cutting, welding, manual rust removal and painting before drilling and fixing. Installing a single bracket requires multiple workers and is time-consuming, with each step needing strict coordination. Errors in any step can easily lead to rework. Existing prefabricated modular components are prefabricated in factories, with cutting, punching, and corrosion protection all industrialized. No welding is required on-site, and quick connections are achieved through bolts and clips. However, the interfaces, mounting hole spacing, and connector specifications of modular brackets and modular distribution boxes from different manufacturers are not yet fully standardized, resulting in situations where brackets cannot be adapted to distribution boxes and thus failing to meet user needs.
