Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
If Fig. 1 is in conjunction with as shown in Fig. 2 to 6, a kind of residual current circuit breaker tripping indicating device, comprise housing 1, in described housing 1, be provided with dropout swing arm 2, indicator collet 3, in described housing 1, be provided with electromagnet 4, in described electromagnet 4, be provided with push rod 41, in described indicator collet 3, be provided with back-moving spring 31, in described housing 1, be hinged with drive block 5, described drive block 5 is provided with elastic reset part 6, on described drive block 5, be extended with pull hook 51, on described indicator collet 3, be extended with projection 32, described drive block 5 has under elastic reset part 6 effect and compresses by pull hook 51 primary importance that projection 32 declines indicator collet 3, the second place with make thread off swing arm 2 actions separated with projection 32 under push rod 41 effect.
In described dropout swing arm 2, be extended with connecting rod 7, on described drive block 5, be extended with push pedal 52, described push pedal 52 has with drive block 5 pushes up the primary importance of pressing connecting rods 7 and the second place that departs from connecting rods 7 with drive block 5.
Described elastic reset part 6, for to be located at the torsion spring 61 on drive block 5, is extended with L-type baffle plate 53 on described drive block 5, inner side and torsion spring 61 ends of described L-type baffle plate 53 are inconsistent.
On described drive block 5, be extended with contact plate 54, described contact plate 54 sides are provided with described push rod 41, and described contact plate 54 is between push rod 41 and L-type baffle plate 53.
Described projection 32 is provided with shoulder block 321, and described shoulder block 321 is suitable with pull hook 51.
The concrete use of the utility model is as follows: during work, electromagnet 4, by amplified current, drives push rod 41 to eject, the contact plate 54 on drive block 5 is pressed on top, and drive block 5 is turned clockwise, and pull hook 51 departs from projection 32, under the effect of back-moving spring 31, indicator collet 3 ejects housing 1 surface, meanwhile, and push pedal 52 drivening rods 7 on drive block 5, swing arm 2 actions make to thread off, complete dropout, because push rod 41 continues to eject and pull hook 51 is positioned at shoulder block below 321, circuit breaker cannot close a floodgate; During combined floodgate, press indicator collet 3, drive block 5 resets under torsion spring 61 effects, and connecting rod 7 is left in push pedal 52, pulls handle, completes combined floodgate.
