Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution equipment boxes, and particularly relates to a spliced ​​box structure with a drawer module. Background Art

[0002] When designing and manufacturing existing power distribution boxes, screw fastening is usually used to install internal modules. Although this traditional fastening method ensures the stability of the module to a certain extent, it causes many inconveniences during disassembly and maintenance. The existing screw fastening method requires maintenance personnel to carry and use tools such as screwdrivers, which not only increases the complexity of maintenance, but may also hinder maintenance work due to the inability to find or use appropriate tools in an emergency. Since screwdrivers and other tools are required for disassembly, the operation process is cumbersome and the disassembly speed is slow. In aircraft emergencies, this disassembly method is not only inefficient, but may also not proceed smoothly due to the limitations of maintenance tools. Utility Model Content
