Abstract:
A linkage device for a lock catch (1) and a moving contact (3) of a circuit breaker. A sliding groove (211) allowing for sliding of an end portion of a circuit breaker connecting rod (4) is arranged at the upper end of a moving contact seat (2); the sliding groove comprises a bent portion (2111) and a straight portion (2112); an abutting arm (11) is arranged at the upper end of the lock catch; the abutting arm is provided with an abutting surface (111). After the circuit breaker is closed, an offline mechanism of the circuit breaker can act on the lock catch to rotate the lock catch, so that the abutting surface releases the locking on a second end of the connecting rod; in this case, the second end of the connecting rod slides into the straight portion of the sliding groove, and the moving contact seat rotates to drive the moving contact to rotate so as to realize disconnection of the circuit breaker.
