Abstract
The utility model relates to a circuit breaker operating mechanism. The operating mechanism comprises a bracket and a handle, wherein the handle is movably connected with the bracket through a shaft, the handle is provided with a reset spring, one end of the reset spring is connected with the handle and the other end is hung on the bracket, the handle is further connected with a connecting rod, the connecting rod is movably connected with a long connecting rod and a short connecting rod through shafts, the other end of the short connecting rod is connected with a plastic pulley which is connected to the bracket, and the bracket is further provided with a copper lock catch, a plastic tripping buckle and a plastic re-tripping buckle which are connected in a matching manner. Compared with the prior circuit breaker operating mechanisms, the circuit breaker operating mechanism is simple in structure and low in cost, and the sensitivity of the circuit breaker operating mechanism is greatly improved due to the adoption of the plastic pulley, the plastic tripping buckle and the plastic re-tripping buckle.
