Description
Technical field
The utility model relates to a kind of power switch devices of control and protective switching device.
Background technique
Currently, the power switch device of the control and protective switching device provided in the market generally comprises power switch, branch
Frame and the handle being movably arranged on bracket, handle are equipped with contact, and swing handle makes contact push or be detached from power supply to open when use
Close to achieve the purpose that on or off, but the power switch device structural stability of above-mentioned control and protective switching device compared with
Difference, the phenomenon that being easy to produce incorrect switching.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide a kind of structure is stronger
The power switch device of stable control and protective switching device.
For this purpose, the utility model adopts the following technical scheme that realize:
A kind of power switch device of control and protective switching device, including bracket and the handle that is movably arranged on bracket,
It is characterized in that: the handle is equipped with wheel, the wheel is equipped with notch, and the bracket is equipped with microswitch and support
Column, the microswitch have movement reed, and movable sleeve is equipped with drive block on the support column, and it is in triangle that the drive block, which has,
Three ends of distribution, connecting rod, the other end that drive block one end is equipped with alignment actions reed are hinged with adjustable shelf, third end is equipped with and resets
Spring is equipped with spring between described adjustable shelf one end and drive block, the other end is equipped with the column for being against wheel outer ring, the reset
The spring other end is connect with bracket.
After adopting the above technical scheme, swing handle drives wheel rotation, when column is located at wheel outer ring, connecting rod is against
Keep microswitch in running order on movement reed, i.e. power supply open state, when column is located at notch, drive block is resetting bullet
It is rotated under the action of spring, so that connecting rod disengaging is acted reed, microswitch is in close state at this time, i.e. power supply off status, is not easy
The phenomenon that generating incorrect switching, the stronger stabilization of structure, the service life is longer.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the schematic perspective view of another visual direction of the utility model.
Specific embodiment
Shown in referring to Figures 1 and 2, the power switch device of control and protective switching device provided by the utility model includes
Bracket 1 and the handle 2 being movably arranged on bracket 1, handle are equipped with wheel 3, and wheel 3 is equipped with notch 4, and bracket 1 is equipped with micro-
Dynamic switch 5 and support column, microswitch 5 have movement reed 6, and movable sleeve is equipped with drive block 7 on support column, and drive block 7 has
In three ends of angular distribution, connecting rod 8, the other end that 7 one end of drive block is equipped with alignment actions reed 6 are hinged with adjustable shelf 9, third
End is equipped with reset spring 10, spring 11 is equipped between 9 one end of adjustable shelf and drive block 7, the other end is equipped with and is against 3 outer ring of wheel
Column 12,10 other end of reset spring are connect with bracket 1.
In the present embodiment, swing handle 2 drives wheel 3 to rotate, and when column 12 is located at 3 outer ring of wheel, connecting rod 8 is against
Keep microswitch 5 in running order on movement reed 6, i.e. power supply open state, when column 12 is located at notch 4, drive block 7 exists
It is rotated under the action of reset spring 10, so that 8 disengaging of connecting rod is acted reed 6, microswitch 5 is in close state at this time, i.e. power supply
Off status, the phenomenon that being not likely to produce incorrect switching, the stronger stabilization of structure, the service life is longer.
