Embodiment
Be described in further detail below in conjunction with accompanying drawing and utility model:
See Fig. 1-Figure 19, it uses the embodiment on GIS three-position switch operation mechanism for the position limiting structure based on magnetic Suspension Technique of the present utility model, described operating mechanism includes and horizontally rotates part and be positioned at a housing, on the base 23 horizontally rotated below part, be provided with three layers of groove cavities: see Figure 11, lowermost is little long rectangular recess or hole 31, and groove internal fixtion has the guiding permanent magnet 16 of similar shape; Middle for greatly enhancing rectangular recess 32, one long end is deformed into triangular groove; What go up most is T-shaped groove 33, and long end extends to base 23 limit; The major axis of three layers of groove overlaps; Be fixed with a slip stop block 15 outstanding downwards horizontally rotating part bottom surface, during revolution, correspond to three layers of described groove cavities.
Also include in addition:
One sliding panel 12, in corresponding to the T-shaped of T-shaped groove 33 on described base 23, horizontal end has in horizontal elongated hole, long end and have H-shaped hole, in H-shaped hole, compression is equipped with little spring 13, and in sliding panel 12 long end, cover has big spring 14; Sliding panel 12 is placed in the T-shaped groove 33 of described base 23 movably, and long end is stretched out outside described GIS three-position switch operation mechanism housing;
One slip stop block 15 is stepped cylindrical shape, large end be placed on facing downward described base 23 greatly enhance on rectangular recess 32, small end stretches out on the horizontal elongated hole of the horizontal end of described sliding panel 12;
One rotates pressing plate 11, and upper end thereof is outer at described housing, lower end jag be inserted in the front end in described sliding panel 12H shape hole; Described rotation pressing plate 11 and sliding panel 12 compress little spring 13, compress big spring 14 with housing side plate.
Described rotation pressing plate 11 is also fixed with sensitive switch pressing plate 19, correspond to the sensitive switch 24 be fixed on outside housing, rotation pressing plate 11 forms pin by pin with split pin hole 21 and is connected and fixed on the gear fixed head 22 of housing.
Described stop block 17 can be fixed on rotational parts with screw thread, and the square hole of stiffener 18 and one of stop block 17 square position coordinate, and prevent stop block 17 from rotating or loosen.
Position limiting structure principle is summarized as follows:
1. see Fig. 1, when Manual operation handle 27 is inserted manual operation axle 26, operating grip 27 is depressed and is rotated pressing plate 11, rotate pressing plate 11 and compress big spring 14 and little spring 13, big spring 14 starts energy storage, little spring 13 promotes sliding panel 12 and moves, sliding panel 12 drives slip stop block 15 to move, the guiding permanent magnet 16 mediated produces magnetic attraction to slip stop block 15, because of the existence of magnetic attraction, slip stop block 15 arbitrarily can not slide at the rectangle breach 34 of sliding panel 12 because of gravity or frictional force, ensure that slip stop block 15 is pushed in process to be suspended on position of center line all the time and to see Figure 13 magnetcisuspension extension effect schematic diagram, slip stop block 15 is pushed centrally line 37 position and moves and a bit ofly to be withstood by the stop block 17 be in equally on center line 37 apart from rear, therefore sliding panel 12 stops mobile, therefore little spring 13 also starts by compressed energy-storage, now operating grip 27 completes and inserts manual operation axle 26, and can operate, once the rotational parts 25 of rotating operation handle 27 mechanism itself starts to rotate, the stop block 17 be fixed on rotational parts 25 leaves center line 37, therefore slip stop block 15 loses obstruction, little spring 13 starts to release and can promote sliding panel 12 and slip stop block 15 until upper bed-plate groove limit, top sees that Figure 14 stop block 17 leaves center line schematic diagram, when stop block 17 during whole for rotation one circle is also about to get back to center line 37 position by rotational parts 25, and start to promote slip stop block 15 and overcome magnetic attraction and move until stop block 17 comes back to center line 37 position to disalignment 37, now slip stop block 15 is withstood by a straight flange of room type groove 32, therefore stop block 15 is withstood, rotational parts 25 can not be rotated again, the now rotation that just completes once whole circle of rotational parts 25 is limited, operating grip 27 now can not operate again, represented the operation of a station simultaneously, see that Figure 15 rotational parts completes a circle transmission schematic diagram, extract operating grip 27, big spring 14 release can promote rotate pressing plate 11 outwards eject, rotate pressing plate 11 and drive sliding panel 12 outwards movement, sliding panel 12 drives slip stop block 15 to move linearly to away from stop block 15 direction, after mobile a bit of distance, slip stop block 15 moves until withstood along the hypotenuse of room type groove 32 to a position in original initial centerline 37, and whole spacing module gets back to home position and state is shown in Figure 16 position limiting structure reset schematic diagram.See Fig. 1.
