Description of drawings
Fig. 1 is the structural representation that the utility model frame-type universal air circuit breaker position snap close and trip gear are loaded on drawout chassis, and Fig. 2 is frame-type universal air circuit breaker position snap close and trip gear structural representation.
Among the figure: 1 guided plate, 2 leading axles, 3 supports, 4 guide plates, 5 bent plates, 6 location axle pin, 7 springs, 8 buckles, 9 plate axles, 10 bent plate axles, 11 base plates, 12 strutting pieces, 13 slide plates, 14 supports, 15 screw mandrel buckle axles, 16 screw mandrel buckles, 17 screw mandrel buckle supports, 18 screw mandrels, 19 springs, 20 release links, 21 hooks, 22 pivot pins, 23 springs, 24 springs, 25 connecting plates, 26 connecting rods.
Execution mode
Referring to Fig. 1, Fig. 2, Fig. 2 is the snap close state.Original position, the hook 21 on the screw mandrel buckle 16 is in the position of hooking pivot pin 22, promptly between pivot pin 22 and buckle 8.When clockwise rotating the drawout chassis operating grip, screw mandrel 18 is clockwise rotated, drive circuit breaker and move to test position from the separation point position, this moment, drawout chassis slide plate 13 carried out rectilinear motion with the guide plate 4 that is contained in slide plate 13 1 ends synchronously under screw mandrel 18 effects.When circuit breaker during in test position, projection on the guide plate 4 promotes guided plate 1 and clockwise rotates around leading axle 2, clockwise rotate by connecting rod 26 pulling connecting plates 25 winding board axles 9, connecting plate 25 rotations have driven the bent plate 5 that links to each other with connecting plate 25 through bent plate axle 10 and have clockwise rotated.Because a side rod plate top of bent plate 5 is equipped with spring 7 and is linked to each other with buckle 8, on the bent plate 5 one side rod plates location axle pin 6 is housed, and connecting plate 25 and buckle 8 link to each other and are connected on the strutting piece 12 through plate axle 9, strutting piece 12 is fixed on the drawout chassis support 14, the L shaped bar plate winding board axle 9 that falls that location axle pin 6 on the bent plate 5 drives on the buckle 8 clockwise rotates, after buckle 8 turns over certain angle, pivot pin 22 on the buckle 8 under another side rod plate has been removed the constraint to hook 21 on the screw mandrel buckle 16, screw mandrel buckle 16 resilience under the effect of spring 19, the projection in screw mandrel buckle 16 stage casings embeds the groove on screw mandrel 18 disks, thereby locking screw mandrel 18 rotates, and reaches the snap close requirement.
Referring to Fig. 1, Fig. 1 is a unbuckled state.In the time will carrying out drawout chassis operating grip rotating operation again, must press release link 20, under the effect of release link 20, hook 21 wire winding rod buckle axles 15 on the screw mandrel buckle 16 promote bent plate 5 clockwise, bent plate 5 rotates counterclockwise around bent plate axle 10, location axle pin 6 has been removed the constraint of make-up plate 8, buckle 8 is under the effect of spring 24, winding board axle 9 rotates counterclockwise, pivot pin 22 is just with 21 lockings of the hook on the screw mandrel buckle 16, thus locking screw mandrel buckle 16, the disk groove that screw mandrel buckle 16 is broken away from the screw mandrel 18, removed locking, recovered the rotating operation of drawout chassis operating grip screw mandrel 18.
