Problems solved by technology
[0002] The existing intelligent leakage circuit breakers on the market have defects in opening and closing indications. Some have no opening and closing indication devices or the opening and closing indications are unclear and difficult to identify. Users cannot intuitively judge intelligent leakage during use. The operating status of the circuit breaker has caused many misoperations or accidents, resulting in economic losses and delays in work

Embodiment Construction
[0010] specific implementation method
[0011] As shown in the figure, a bolt-shaped push rod 8 is set above the moving contact bracket 5 in the base 1 of the intelligent earth leakage circuit breaker; There is a rotating shaft in the fan-shaped center of the fan-shaped opening and closing indicator turntable 10, which is fixed in the concave rotating groove of the middle cover through the U-shaped turntable fixed pressure block 11 to prevent it from turning out; there is an obvious sign on the opening and closing indicator turntable 10 Red closing and green opening color markings, red above the green, identification opening and closing indicator 3 is pasted on the upper right corner of the outer cover 4; a spring 9 that can be compressed and released is set on the bolt-shaped push rod 8, and the length and force of the spring are released. When the push rod can be pushed down, the upper end of the spring is connected with the middle cover, and the lower end is connected with ...

A breaking and closing indication device comprises a base, a middle cover, a breaking-closing indication board, an outer cover, a moving contact support, a moving contact, a fixed contact, a push rod, a spring, a breaking-closing indication dial, and a dial-fixing press block. A synchronous interlocking device is disposed on a moving contact device of an intelligent leakage breaker. The push rod is arranged above the moving contact support of the base and is made into a bolt shape. The push rod penetrates through the middle cover to be connected with a lower corner of the breaking-closing indication dial. The breaking-closing indication dial is fixed at a left upper corner of the middle cover. The center of the breaking-closing indication dial is provided with a rotary shaft which is fixed in a concave rotation cavity of the middle cover through the U-shaped dial-fixing press block. The breaking-closing indication dial is provided with a vivid red close sign and a vivid green break sign. The red close sign is arranged above the green break sign. The breaking-closing indication board is attached to an upper right core of the outer cover. The spring is sleeved on the push. When released, force of the spring pushes down the push rod. The breaking and closing indication device allows a user to see and judge the operation condition of the intelligent leakage breaker during use.
Description
technical field [0001] The invention relates to an electrical appliance indicating device, in particular to an opening and closing indicating device for an intelligent leakage circuit breaker. technical background [0002] The existing intelligent leakage circuit breakers on the market have defects in opening and closing indications. Some have no opening and closing indication devices or the opening and closing indications are unclear and difficult to identify. Users cannot intuitively judge intelligent leakage during use. The operating state of the circuit breaker has caused many misoperations or accidents, resulting in economic losses and delays in work. content of the invention [0003] Aiming at the technical deficiencies of the existing above-mentioned products, the object of the present invention is to provide an on-off indicating device, which consists of a base, a middle cover, an on-off indicator, an outer cover, a moving contact bracket, a moving contact, a stati...
