The invention belongs to the technical field of power distribution cabinet accessories, and particularly relates to a self-suction type power distribution cabinet door hinge. The self-suction type power distribution cabinet door hinge comprises a base, two symmetrically-distributed connecting plates are hinged to the interior of the base, a connecting frame is jointly hinged to the interiors of the two connecting plates, a mounting frame is hinged to the outer side of the upper end of the connecting frame, a movable frame is hinged into the base, two symmetrically-distributed hinged plates are hinged to the inner side of the movable frame, the hinged plates are hinged to the connecting plates, and two symmetrically-distributed sliding rails are arranged on the base. A sliding rail, a limiting rod, a connecting plate and other structures are additionally arranged on the base, so that when the mounting frame rebounds, the limiting rod can slide in the track of the sliding rail, when a cabinet door is closed to 45 degrees, the limiting rod passes through the topmost end of the sliding rail and then can automatically slide down along the sliding rail, so that the cabinet door is automatically closed, and therefore, the cabinet door can be prevented from being closed tightly by workers.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinet accessories, in particular to a self-priming power distribution cabinet door hinge. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. [0003] The power distribution cabinet door hinges in the prior art, during production, are very cumbersome because of their sp...
