The invention discloses a heat dissipation and drying electric cabinet which is convenient for movement and positioning, which comprises a cabinet body, a chute, a support plate, a far-infrared heating plate, and a semiconductor refrigeration sheet; A lifting mechanism fixed on the bottom of the cabinet is installed in the space of the cabinet. The lifting mechanism includes a worm wheel, a worm, a rotating shaft, a fixed rod, a driving bevel gear, a driven bevel gear, a screw, and a screw sleeve. Rollers are installed at the lower end of the screw sleeve. A connecting rod is installed between the sleeves. The invention is simple in structure, easy to use, strong in practicability, safe and reliable, reduces the influence of humidity on the high-voltage switch cabinet, and can effectively reduce the temperature inside the cabinet; by rotating the worm wheel, the contact between the roller and the bottom surface can be indirectly adjusted, so that the cabinet can be conveniently The body is moved and positioned, and the operation is fast and flexible.
