Abstract

The invention provides a self-locking device for a switch cabinet valve mechanism. The self-locking device comprises a supporting frame (10), a rotating piece (20), a limiting assembly (30), and a reset spring (40). The rotating piece is rotatably connected to the supporting frame. The limiting assembly is slidably connected with the supporting frame, the limiting assembly is used for locking or unlocking a closing state of the valve mechanism by sliding. One end of the reset spring is used for applying force to the limiting assembly, and the other end of the reset spring is used for applyingforce to the supporting frame. The rotating piece can slide in the direction of unlocking the closing state relative to the supporting frame by rotating the abutting-resisting the limiting assembly, so that the reset spring can store energy, the energy-storage reset spring is used for applying force to the limiting assembly to enable the limiting assembly to slide in the direction of locking the closed state. The self-locking device can automatically unlock the closing state of the valve mechanism when the handcart is pushed into the cabinet body; and the closing state of the valve mechanism is automatically locked after the handcart is moved out of the cabinet body. In addition, the invention further provides a switch cabinet comprising the self-locking device.

Description

technical field [0001] The invention relates to a locking device for a valve mechanism of a switch cabinet, in particular to a self-locking device capable of automatically locking the valve mechanism of a switch cabinet after the handcart is moved out, and a switch cabinet including the same. Background technique [0002] In the removable switch cabinet, the handcart is connected to the static contact fixedly installed in the cabinet through the moving contact of the contact arm system, which ensures the continuity of the main power distribution circuit. During use, the moving contact of the handcart and the static contact of the cabinet are connected or disconnected by pushing in or removing the handcart. Static contacts are usually connected to live parts of the power distribution system. Usually, a valve mechanism is set between the handcart and the static contact in the cabinet, and the valve mechanism can reach the closed state after the handcart moves out of the cabin...
