The invention discloses a releasing mechanism of a small circuit breaker. The problems that a rotating shaft of a support of a releasing mechanism of an existing small circuit breaker and a hinging shaft of a locking buckle are noncoaxial, deflection is prone to occurrence during rotation, and buckle slippage is caused are mainly solved. The releasing mechanism is characterized in that a first hinging shaft (11) for being hinged to a circuit breaker shell and a second hinging shaft (12) for being hinged to a locking buckle (2) are arranged on a support (1), and the first hinging shaft (11) and the second hinging shaft (12) are coaxially arranged. According to the releasing mechanism of the small circuit breaker, the locking buckle and a bouncing buckle corresponding to the locking buckle are hinged to the support, the first hinging shaft for being hinged to the circuit breaker shell and the second hinging shaft for being hinged to the locking buckle are arranged on the support, and the first hinging shaft and the second hinging shaft are coaxially arranged. In this way, when the circuit breaker is turned on or turned off, rotating of the releasing mechanism is more stable, and buckle slippage caused by deflection can be avoided.
Description
technical field [0001] The invention relates to the field of circuit breakers, in particular to a tripping mechanism of a small circuit breaker. Background technique [0002] The circuit breaker has the characteristics of advanced structure, reliable performance, strong breaking capacity, beautiful and compact appearance, etc. It is used for the overload and short circuit protection of lighting, power distribution lines and equipment in office buildings, residential buildings and similar buildings, and can also be used as a circuit breaker. It is used for infrequent on-off operation and conversion. [0003] The tripping mechanism of the existing circuit breaker includes a bracket, a jumper and a lock. The publication number is "CN 104299864 A", and the Chinese patent titled "miniature circuit breaker" discloses a miniature circuit breaker. The rotation of the bracket The shaft and the hinge shaft of the lock are not on the same axis, so it is easy to deflect when turning, r...
