Mechanical interlocking structure of dual-power-supply miniature circuit breaker

The utility model discloses a dual-power-supply micro-circuit breaker mechanical interlocking structure which is provided with an interlocking support, a spring bolt piece, a cover plate and a locking bolt, a device is clamped and connected between dual power supplies, and a positioning piece connected to the spring bolt piece can abut against a push handle of one power supply, so that the device can be locked and unlocked. When the power supply is replaced, the spring bolt piece is directly pulled to slide towards one side, so that the positioning piece can abut against the push handle of the other power supply, the operation is simple, the use is very convenient, the cost is greatly reduced, and the power supply is applied to the field of electrical equipment. 本实用新型公开了一种双电源微断机械联锁结构，此双电源微断机械联锁结构中设置了互锁支架、锁舌片、盖板和锁紧螺栓，将装置夹持连接在双电源之间，且锁舌片上连接的定位片能够抵住其中一个电源的推柄，更换电源时直接拉动锁舌片向一侧滑动，使得定位片能抵住另外一个电源的推柄即可，操作简单，使用非常方便，且大大降低了成本，此实用新型用于电气设备领域。
