Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the anti-misoperation apparatus had in a kind of omnipotent breaker of defencive function.
For achieving the above object, the utility model provides following technical scheme:
Anti-misoperation apparatus in a kind of omnipotent breaker, comprise drawout chassis and handle, rotating screw mandrel is rotatably connected in described drawout chassis, described screw mandrel one end offers for hexagonal/interior corner groove in coordinating with handle, it is characterized in that: described drawout chassis is provided with anti-misoperation apparatus, this anti-misoperation apparatus comprises
Baffle plate, can sliding motion for blocking groove;
Resetting device, returns to initial position for baffle plate, described baffle plate offers the open slot passed for handle, and described handle is provided with for the one end of inserting groove and bears torsion and play little connecting rod than it.
The utility model is set to further: described resetting device comprises extension spring, and described extension spring one end is connected with drawout chassis, and the other end is connected with baffle plate.
The utility model is set to further: described resetting device comprises Compress Spring, and described Compress Spring is arranged between drawout chassis inwall and baffle plate.
The utility model is set to further: the sidewall of described drawout chassis offers chute, and described baffle plate is convexly equipped with slide block, and described slide block is connected with chute slippage and forms resetting device.
The utility model is set to further: described connecting rod is replaceable.
By adopting technique scheme, the groove that screw mandrel is offered is sheltered from by resetting device by baffle plate when initial, baffle plate slippage is promoted in handle insertion opening groove, handle is enable normally to insert rotary screw rod in groove, do not affect normal running, therefore, this utility model has the advantages that to avoid misoperation, pusher energy storage control device is after running to the end, now, handle will not rotate, in order to avoid continuing the torsion being applied to handle, and the damage to this circuit breaker internal part, connecting rod can rupture, avoid damaging for the protection of this circuit breaker internal part.
