The drawer-type low-voltage distribution cabinet of the utility model has a simple structure, convenient maintenance and operation, and good heat dissipation and dustproof performance. However, the number of circuit components carried by a single drawer of the drawer-type distribution cabinet is limited. In order to increase the carrying capacity of the distribution cabinet, a multi-layer drawer storage area will be set at its upper end. As the number of layers increases, its own height also increases. When the components in the upper drawer need to be maintained, the staff needs to use ladders and other height-increasing tools for assistance, and it is very inconvenient to stand at a high place for maintenance, which affects the staff's operating efficiency. Therefore, a drawer support lifting structure is needed at the upper end of the drawer-type low-voltage distribution cabinet. Utility Model Content
