The purpose of this utility model is exactly cannot distinguish for existing circuit-breaker switching on-off the technological deficiency that artificial divide-shut brake or fault trip cause, a kind of circuit breaker failure tripping indicating device is provided, for miniature circuit breaker adds the function of faulty indication, when in use circuit breaker becomes gate-dividing state from "on" position, can be judged by the indicator post in inspection hole whether this dropout is fault trip, when after failture evacuation, only circuit breaker need be closed again, indicating device can complete automatically by the switching of alarm condition to initial condition.Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of circuit breaker failure tripping indicating device, it comprises tripping, it is characterized in that: described tripping is provided with tripping boss, tripping boss can contact with rear boss with the front boss of indicating device respectively in tripping rotation process, promotes indicating device and moves back and forth in the horizontal direction.
Further, described indicating device is arranged in the installation chute of circuit breaker base.
Further, described tripping is contained in tripping rotating shaft, and tripping can be driven to rotate counterclockwise by dynamic contact mechanism and tripping boss is contacted with front boss.
Further, described tripping connects one end of connecting rod, and the other end of connecting rod is connected on handle, and tripping can be rotated at handle clockwise under influence and tripping boss is contacted with rear boss.
Further, described dynamic contact mechanism is connected with reaction spring, by reaction spring thrust.
Further, described tripping is fitted with snap close when fault-free "on" position and is contacted.
Further, described indicating device is slide block, and slide block can slide in the installation chute of circuit breaker base, has bit-avoiding slot between the front boss of indicating device and rear boss, tripping boss is respectively with front boss and rear boss contact process, and tripping boss can stretch into bit-avoiding slot.
Beneficial effect
A kind of circuit breaker failure tripping indicating device that the utility model provides, for miniature circuit breaker adds the function of faulty indication, utilize tripping to the effect of indicating device, when in use circuit breaker becomes gate-dividing state from "on" position, can be judged by the indicator post in inspection hole whether this dropout is fault trip, when after failture evacuation, only circuit breaker need be closed again, indicating device can complete automatically by the switching of alarm condition to initial condition.Whole mechanism only need do simple modifications to existing circuit breaker and can realize, and structure is simple, improves circuit breaker maintenance efficiency.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in accompanying drawing 1 ~ 5, a kind of circuit breaker failure tripping indicating device, it comprises tripping 1, tripping 1 is provided with tripping boss 101, tripping boss 101 can contact with rear boss 202 with the front boss 201 of indicating device 2 respectively in tripping 1 rotation process, promotes indicating device 2 and moves back and forth in the horizontal direction.
Described indicating device 2 is arranged in the installation chute 3 of circuit breaker base.
Described tripping 1 is contained in tripping rotating shaft 4, and tripping 1 can be driven to rotate counterclockwise by dynamic contact mechanism 5 and tripping boss 101 is contacted with front boss 201.
Described tripping 1 connects one end of connecting rod 6, and the other end of connecting rod 6 is connected on handle 7, and tripping 1 can be rotated at handle 7 clockwise under influence and tripping boss 101 is contacted with rear boss 202.
Described dynamic contact mechanism 5 is connected with reaction spring 8, by reaction spring 8 thrust.
Described tripping 1 is fitted with snap close 9 when fault-free "on" position and is contacted.
Described indicating device 2 is slide block, slide block can slide in the installation chute 3 of circuit breaker base, bit-avoiding slot 203 is had between the front boss 201 of indicating device 2 and rear boss 202, tripping boss 101 is respectively with front boss 201 and rear boss 202 contact process, and tripping boss 101 can stretch into bit-avoiding slot 203.
The course of work of whole mechanism is, when circuit breaker breaks down dropout, tripping 1 will be separated with the mating surface of snap close 9, tripping 1 will be rotated counterclockwise around tripping rotating shaft 4, and the inactive state of dynamic contact mechanism 5 is also destroyed simultaneously, is rapidly to open position moves in the effect lower moving contact mechanism 5 of reaction spring 8, thus drive tripping 1, tripping boss 101 is contacted with indicating device 2 front boss 201, and the stressed backward left movement of indicating device 2, to the position of exposing inspection hole, completes fault trip instruction.
After user fixes a breakdown, when again being closed a floodgate by the circuit breaker of instruction of breaking down, indicating device 2 can be made smoothly to return to initial position.Concrete grammar is that after breaking down, indicating device is in alert locations, and circuit breaker is in the state of separating brake.Driving handle 7 makes breaker closing, thus drivening rod 6, under the effect of connecting rod 6, dynamic contact mechanism 5 is moved to closing position by open position, in motion process, tripping boss 101 contacts with indicating device 2 rear boss 202 being in faulty indication position, indicating device 2 is stressed to move right to initial position, completes indicating device 2 by the switching of alert locations to initial position.
Carry out divide-shut brake when not breaking down and threading off, tripping 1 will contact all the time with snap close 9, and tripping boss 101 cannot contact with indicating device 2 rear boss 202 with the front boss 201 of indicating device 2, therefore normal divide-shut brake can not cause the misoperation of indicating device 2.
The utility model is the function that miniature circuit breaker adds faulty indication, utilize tripping to the effect of indicating device, when in use circuit breaker becomes gate-dividing state from "on" position, can be judged by the indicator post in inspection hole whether this dropout is fault trip, when after failture evacuation, only circuit breaker need be closed again, indicating device can complete automatically by the switching of alarm condition to initial condition.Whole mechanism only need do simple modifications to existing circuit breaker and can realize, and structure is simple, improves circuit breaker maintenance efficiency.
