Electric door of low-voltage switch cabinet

Abstract

The invention relates to the technical field of low-voltage switch cabinets, and discloses a low-voltage switch cabinet electric door which comprises a cabinet body, a cabinet door hinged to the cabinet body and capable of opening or closing the cabinet body, an automatic door opening and closing structure arranged between the cabinet body and the cabinet door and a locking structure arranged between the cabinet body and the cabinet door. The locking structure comprises a mounting block arranged on the cabinet body, a locking groove concavely formed in the upper top surface of the mounting block, a fixed block arranged above the mounting block on the cabinet door, a telescopic groove concavely formed in the lower bottom surface of the fixed block, and a locking block which is arranged in the telescopic groove in a lifting manner and is matched with the locking groove in a penetrating manner during descending or is separated from the locking groove during ascending; according to the electric door of the low-voltage switch cabinet, the anti-theft performance of the low-voltage switch cabinet is improved while the door of the low-voltage switch cabinet is automatically opened and closed.

Description

technical field [0001] The invention relates to the technical field of low-voltage switch cabinets, in particular to an electric door of a low-voltage switch cabinet. Background technique [0002] Low-voltage switchgear can realize the conversion or control of electric energy. Conventional low-voltage switchgear doors are manual. After opening the cabinet door during maintenance, the cabinet door is easy to collide with the cabinet under the action of inertia and cause damage. In severe cases, it will be damaged. As a result, the cabinet door rebounds, and it is easy to squeeze the hands of the workers, so the automatic door opening and closing structure appears. [0003] The Chinese patent with the application number CN201520362889.8 discloses an automatic advertising door for pedestrian passages in a community, comprising a doorpost and a door frame, the door frame is rotatably connected to the door post through a hinge, and a door lock is provided between the other end of...

Problems solved by technology

[0004] The automatic door opening and closing structure controls the rotation of the machine arm through the door opener, and the machine arm transmits power to the slider in the door frame chute, so that the slider makes a reciprocating linear motion in the door frame, driving the door frame to rotate, and realizing the opening or closing of the door frame. , and lock the door frame through the control host to control the electromagnetic lock after the door is closed. However, in order to ensure the effect of automatic opening and closing, the automatic door opening and closing structure uses the electromagnetic lock as the locking tool. The locking function will disappear, and the overall anti-theft performance is poor
