SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing an intelligent interlocking type switch cabinet.
An intelligent interlocking switch cabinet comprises a cabinet body and a cabinet door, wherein a lock body is connected to the inner wall of the cabinet body, and an interlocking device corresponding to the lock body is connected to the inner wall of the cabinet door; the interlocking device comprises a fixed frame, a lock cylinder, an electromagnet and an eccentric wheel; the fixing frame is connected with the inner wall of the cabinet door, one end of the lock cylinder is connected with the connecting plate, and the other end of the lock cylinder penetrates through the fixing frame and faces the through groove in the middle of the lock body; the connecting plate is connected with the side wall of the fixing frame through a return spring; the electromagnet is connected with the side wall of the fixing frame, the power supply end of the electromagnet is connected with an internal power supply of the switch cabinet through a wire, and a magnetic substance matched with the electromagnet is further arranged on the connecting plate; the eccentric wheel is connected with the handle through the rotating shaft, the handle is located on the outer wall of the cabinet door, and when the reset spring is in a free state, the short shaft end of the eccentric wheel abuts against the outer wall of the connecting plate.
Preferably, the cabinet door is made of high-strength aluminum alloy, so that the portability and the stability of the whole device can be guaranteed.
Preferably, the number of the lock cylinders is two, and the two lock cylinders are distributed in an up-and-down symmetrical mode.
Preferably, the front end of the lock cylinder is provided with a guide inclined plane, and the lock cylinder can be more conveniently inserted into the lock body through the guide inclined plane.
Preferably, the fixing frame is connected with the inner wall of the cabinet door through bolts.
Has the advantages that:
through the mode of mechanical and electrical bidirectional interlocking, the switch cabinet can be guaranteed to be opened by outsiders under the condition that electricity exists in the switch cabinet, so that the life safety of operators is guaranteed forcibly, and the electric shock phenomenon is prevented.
Concretely, can be through the mode of rotatory handle to drive the eccentric wheel and rotate to major axis end butt connecting plate, and overcome reset spring's elastic force and insert the lock core in the lock body, realize mechanical interlocking, and when cubical switchboard inside has the electricity, the electro-magnet circular telegram is given birth to magnetism, attracts magnetic substance to drive the connecting plate and removes to the mount direction, thereby realizes that the lock core inserts the purpose in the lock body. Through mechanical and electrical two-way assurance, can guarantee the security of cubical switchboard, prevent that operating personnel from opening by mistake under the electrified condition to cause the unnecessary incident.
