Abstract
The utility model relates to a switch operation device, which comprises a handle supporting stand and a handle, wherein the handle can be switched between the 'opening' position and the 'closing' position of a handle frame. The switch operation device is characterized by further comprising a padlock device, a slot is arranged on the handle supporting stand, the slot is arranged between the 'opening' position and the 'closing' position of the handle frame, the padlock device is mounted in the slot, and can up and down slide in the slot, and when the padlock device extends outside the slot, thehandle can be locked on the 'opening position' or the 'closing' position. The switch operation device can lock the handle on the 'opening' position or the 'closing' position, and is safer and reliableto switch.
Description
Technical field
The utility model relates to the switching technique field, particularly a kind of switch operation device.
Background technology
Existing switch operation device generally comprises handle bracket and handle; Handle bracket is provided with out " position and off-position, handle can be changed between " opening " position and the off-position with being intended to.When circuit that switch is controlled in actual production or overhaul of the equipments, handle need be fixed on the off-position,, prevent maintainer's accidental shock with open circuit.When the equipment of switch control normally moved, it was closed to need to keep circuit to continue, and handle will guarantee to be in " opening " position.Often occur such situation in the reality, when circuit or overhaul of the equipments, the someone has opened by mistake switch, should be in " pass " state of switch and push " opening " state, the accident that causes device damage and maintainer to get an electric shock; In the normal operation of equipment, because should being in the switch of opening state, operating personnel's error pushed the state that closes, make and the equipment sudden power cause production loss.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of switch operation device that switch knob can be locked in " opening " position or off-position is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of switch operation device, comprise handle bracket and handle, handle can be changed between " opening " position on the handle frame and off-position, it is characterized in that: also comprise hanging locking device, handle bracket is provided with slot, this slot is positioned at handle frame and " opens " between position and the off-position, hanging locking device is installed in the slot, hanging locking device can slide up and down in slot, handle lock can be fixed on " opening " position or off-position when hanging locking device stretches out slot.
As further improvement of the utility model, hanging locking device is an inserted sheet, and the both sides of hanging locking device are provided with double wedge, the upper end of slot is provided with the spacing catch that matches with double wedge, when hanging locking device stretched out slot, spacing catch blocked the double wedge on the hanging locking device, prevented that hanging locking device breaks away from slot.
Hanging locking device is provided with a through hole, with the convenient padlock of installing.
The utility model is provided with hanging locking device between " opening " position of handle and off-position, hanging locking device is pulled up, make hanging locking device stretch out slot, then hanging locking device is fixed on handle " opening " position or off-position, hanging locking device is pressed, and handle can freely be changed between " opening " position and off-position.Offer a through hole on the hanging locking device, after the padlock, just hanging locking device is fixed on the position of stretching out slot in this through hole padlockable, through hole, handle lock is fixed on " opening " position or off-position, operation prevents to make the mistake.
In sum, the utlity model has can be with the beneficial effect of handle lock in " opening " position or off-position, makes the switch safety and reliability.
