Electrical automation instrument cabinet

The utility model belongs to the technical field of instrument cabinets, and particularly relates to an electrical automation instrument cabinet which comprises a wall body, a driving box is fixedly connected to the front face of the wall body through screws, and a base is fixedly connected to the position, located below the driving box, of the front face of the wall body through screws. The clamping block is extruded by the inner wall of the groove and drives the sliding plate to extrude the compression spring, so that the clamping block enters an inner cavity of the barrel, when the fixing seat enters the inner cavity of the groove and moves to the position corresponding to the pin pipe, the compression spring pushes the sliding plate to slide under the reactive force, the sliding platedrives the clamping block to move out of the barrel, and the clamping block is clamped with the pin pipe; through the arrangement of the structure, the instrument cabinet has the advantage that when aworker installs the instr
