The invention discloses an explosion-proof door of a switch cabinet with promoted locking function, which solves the problems of insufficient strength, low reliability or cabinet door locking complexity, low operation efficiency and the like after the handcart room cabinet door of the conventional mobile switch cabinet is locked. A limit mounting bracket and a mounting bracket are welded on a door panel, operation locking mechanisms are assembled in the limit mounting bracket and the mounting bracket, the lateral surface of the door panel is assembled with a multifunctional hinge, and the operation locking mechanism is connected with the multifunctional hinge. Through the operation locking mechanisms, the related parts inside the hinge produce relative sliding translation to drive the dropping or rising of the door panel so as to implement locking or unlocking of the door panel and the cabinet body. The explosion-proof door has the advantages of high strength, high reliability, simple locking of cabinet door and high operation efficiency after locking.
Description
technical field [0001] The invention relates to an explosion-proof door of a switch cabinet with the function of lifting and locking. Background technique [0002] With the rapid development of my country's electric power and switchgear manufacturing industry, armored removable AC metal-enclosed switchgear has been widely used. At the same time, people have put forward higher and more comprehensive requirements for the operation, quality and safety performance of switchgear. requirements. Many switch products currently on the market have the common problems of complicated operation, low strength after locking, and poor reliability on the cabinet door panels that are in direct contact with the operator. Contents of the invention [0003] The purpose of the present invention is to provide a switchgear explosion-proof door with the function of lifting and locking, so as to solve the problem of insufficient strength, low reliability, complicated locking of the cabinet door and...
