The invention provides an electrical cabinet base structure with a synchronous rotation function, and belongs to the field of electrical cabinets to solve the problem that a heavy cabinet is difficultto move and is poor in stability when moved. The electrical cabinet base structure with the synchronous rotation function is used for a heavy cabinet. A base includes a plurality of universal casters. Each universal caster includes a wheel seat, and comprises therein a rolling mechanism and a steering mechanism. The wheel seat is in rolling connection with a roller through the rolling mechanism,and is rotatable connection with a connecting plate through the steering mechanism. The plurality of universal casters are fixed to the bottom of the cabinet through the connecting plates. The steering mechanism includes a connecting sleeve fixed to the wheel seat. A main gear is coaxially fixed to the outer wall of the top of the connecting sleeve. The electrical cabinet base structure further comprises a central wheel movably connected to the bottom of the cabinet through a central shaft. The outer edge of the main gear and the outer edge of the central wheel are provided with meshed teeth.The connecting sleeves of the plurality of universal casters are meshed with the main gear through the central wheel to form a linkage rotating structure. The electrical cabinet base structure also comprises an orientation mechanism. The base structure makes it easy to move the heavy cabinet.
