Problems solved by technology
The switchgear door lock currently used includes a lock body, a lock springboard hinged with the lock body and a spring torsion spring. The structure of the push plate lock core opening mechanism that cooperates with the lock springboard is complicated to set, inconvenient to use, and high in cost.
In addition, some bolts are welded to the cabinet door. This method is likely to cause asymmetry of the door panels, and the bolts are easily deformed, making it difficult to install the door panels.

The invention relates to a self-locking device for opening and closing a cabinet door. The self-locking device comprises a cabinet body and the cabinet door, wherein a first hook is fixed at the side of the cabinet body; a protecting cover is fixed at the side of the cabinet door; the protecting cover is internally connected with a second hook and a handle by connecting pieces; and the second hook and the handle are arranged on the same plane. The self-locking device is simple in structure; when the door is closed, the second hook is automatically blocked into the first hook, so that the door is automatically closed without back and forth swinging; when the door is opened, the handle is moved, and the second hook is separated from the first hook, so that the door can be opened; therefore, the self-locking device is flexible and convenient in operation, and the service life of the door is prolonged.
Description
technical field [0001] The invention relates to a switch cabinet door, in particular to a self-locking device for a switch cabinet door. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, various AC contactors, etc. It needs to use doors to cover the cabinet. The inner cavity of the cabinet needs to be opened and closed frequently during use, so it is required that the cabinet door and the cabinet body should be closely matched and the cabinet door should rotate flexibly. The switchgear door lock currently used includes a lock body, a lock springboard hinged with the lock body and a spring torsion spring, and the push plate lock core opening mechanism that cooperates with the lock springboard is structurally complex to set, inconvenient to use, and high in cost. In a...
