The invention discloses a liftable central-positioned low-voltage switch cabinet and relates to the technical field of a switch cabinet. The switch cabinet comprises a cabinet body, wherein a semi-enclosed external mechanism is arranged on the periphery of the cabinet body, a motor box is arranged at a bottom end of the semi-enclosed external mechanism, a driving mechanism is arranged in the motorbox, a lifting assembly is arranged in the semi-enclosed external mechanism, and the lifting assembly is connected with the driving mechanism. By starting a motor, the motor drives a first bevel gearto rotate through a rotating shaft, so a second bevel gear is driven to rotate, the cabinet body rises and falls under cooperation of a sliding block and a screw, moreover, a clamping block at a rearend of the cabinet body is matched with a sliding groove, so the cabinet body rising and falling stability is improved. Compared with the prior art, the switch cabinet is more flexible, and a workercan conveniently detect and maintain internal instruments and the like.
