Summary of the invention
The utility model be solve three-position switch operation mechanism in existing switch cubicle position-limit mechanism complex structure, take up room large technical problem, devise a kind of position-limit mechanism of three station operating mechanisms, lifted by operating grip or discharge elastic spacing pin assemblies, make elastic spacing pin realize grafting fast with the spacing hole in operation rotating shaft to coordinate, thus reach the operation locking of rotating shaft and the object of release.
The utility model is the technical scheme realizing goal of the invention employing, a kind of position-limit mechanism of three station operating mechanisms, the structure of above position-limit mechanism comprises rotational positioning operation rotating shaft on a mounting board, its key is: also comprise in the structure of described position-limit mechanism and radially slide spacing elastic spacing pin assemblies on a mounting board along operation rotating shaft, operation rotating shaft is provided with spacing hole, and elastic spacing pin assemblies has grafting by the operating grip that end is arranged with the spacing hole in operation rotating shaft and coordinates.
The utility model adopts reliably spacing in the spacing hole of the spacer pin update rotating shaft of intermediate isolating position Compress Spring potential energy, when forwarding combined floodgate or ground connection position to, outwards operating grip is dialled with hand, spacer pin leaves the spacing hole in operation rotating shaft, operation rotating shaft can be rotated to combined floodgate or ground connection position, now Compress Spring is in energy storage state, achieves the object of rapid closing, steady lock operation rotating shaft.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the spacing schematic diagram of intermediate isolating in the utility model.
Fig. 2 closes a floodgate or earthing position schematic diagram in the utility model.
In accompanying drawing, 1 representative operation rotating shaft, 1-1 represents spacing hole, and 2 represent locating piece, and 3 represent reference column, and 4 represent pad, and 5 represent operating grip, and 6 represent split pin, and 7 represent mounting panel, and 8 represent spacer pin, and 9 represent stage clip.
