Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
By Fig. 1 composition graphs 2, 3, 4, 5, shown in 6, a kind of on-load switch fuse combined electric apparatus operating mechanism, comprises support 1, operation axis 2, swinging plate 3, first gear 4, combined floodgate main shaft 5 and combined floodgate energy-stored spring 6, the first described gear 4 and swinging plate 3 are all located on operation axis 2, specifically, operation axis 2 comprises operating axis and separating brake axle, swinging plate 3 is located on separating brake axle, operating grip is inserted in operating axis and blocks mutually with latch, and the first described gear 4 to be located on operating axis and to be rotatably assorted with operating axis, and described combined floodgate main shaft 5 is provided with the second gear 7, driving-disc 8, combined floodgate cam 9, connecting lever 10 and energy storage cam 20, described connecting lever 10 is connected with combined floodgate energy-stored spring 6, described driving-disc 8 is rotatably assorted with combined floodgate main shaft 5, described combined floodgate main shaft 5 is rotatably assorted with connecting lever 10, specifically, driving-disc 8 drives combined floodgate main shaft 5 to rotate, and combined floodgate main shaft 5 drives connecting lever 10 to rotate, connecting lever 10 rotating band dynamic circuit connector lock energy-stored spring 6 rotates, and combined floodgate energy-stored spring 6 can drive energy storage cam 20 to rotate by the elasticity of spring after crossing mid point.Described combined floodgate cam 9 is corresponding with swinging plate 3, and carry out energy storage by energy storage cam 20 pairs of tripping springs during combined floodgate, swinging plate 3 is pushed the second place by combined floodgate cam 9 simultaneously.The second described gear 7 is meshed with the first gear 4, is provided with arrangement of clutch 11 between the second described gear 7 and driving-disc 8.Described arrangement of clutch 11 comprises roller 12 and pallet 13, described pallet 13 is located on the second gear 7, described driving-disc 8 is provided with the breach 81 suitable with pallet 13, described roller 12 is located on swinging plate 3, the primary importance that described roller 12 has a normal condition and the second place backed down pallet 13 when closing a floodgate pallet 13 is separated with driving-disc 8.When needs close a floodgate, pallet blocks the breach of driving-disc, and the second pinion rotation drives driving-disc to rotate, thus drives combined floodgate main shaft to rotate.Shown in Fig. 4, Fig. 5, roller is in primary importance, when combined floodgate completes, combined floodgate cam driven swinging plate rotating mechanism closes a floodgate, the rotation of swinging plate simultaneously drives roller to go to the indentation, there of driving-disc around operation axis dextrorotation, thus can pallet be backed down, when making to have closed a floodgate, the rotation of the second gear no longer drives driving-disc to rotate, thus avoids the generation occurring operating mechanism reclosing phenomenon.It should be noted that in addition, breach original position due to driving-disc is fixing, and when combined floodgate energy storage completes, driving-disc breach is just in time corresponding with the position of roller, and roller just in time can back down pallet, make the second gear idle running, thus realize the clutch to the second gear and driving-disc.The invention has the beneficial effects as follows, adding arrangement of clutch makes product when reliably closing a floodgate, second pinion rotation no longer drives driving-disc to move, thus the potential safety hazard avoiding reclosing operation to exist, ensure that safety and the useful life of mechanism, avoid the potential safety hazard that reclosing operation exists, and the present invention also has simple and reasonable, the slim and graceful advantage easily of operation.
Be provided with drive motors 14 outside described support 1, described drive motors 14 is provided with the 3rd gear 15, and the 3rd described gear 15 to be located in support 1 and to be meshed with the second gear 7.When such structure avoids and adopts sprocket wheel to connect, chain easily ruptures, and there is the problem of potential safety hazard.
Described support 1 is provided with the ratchet 16 suitable with the second gear 7.Such structure avoids operation axis in thermal energy storage process to drive operating grip revolution, safer.
The gearratio of described first gear 4 and the second gear 7 is 2:1 or 3:1.Bull gear drive is driven by pinion, can be more laborsaving.Certainly according to the size in space in support, different gear ratios can be selected.
Described operation axis 2 is provided with and indicates groove 17 and the through hole 19 for accommodating latch 18, and described sign groove 17 parallels in same plane with through hole 19.Specifically, indicate groove to parallel in the cross section of operation axis with through hole.The design indicating groove can play marked effect to operating grip, and more convenient operating grip is inserted into latch place and blocks mutually with latch.
Every technical staff's notice: although the present invention describes according to above-mentioned embodiment, invention thought of the present invention is not limited in this invention, and the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
