Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
By Fig. 1 composition graphs 2, 3, 4, 5, 6, shown in 7, a kind of spring operating mechanism, comprise header board 1, middle plate 2 and base plate 3, operating axis 4 is provided with between described header board 1 and base plate 3, energy storage axle 5 and output main shaft 6, described operating axis 4 is connected with energy storage axle 5, described energy storage axle turns to certain position can drive output main axis, separating brake semiaxis 7 and installation shaft 8 is provided with between described middle plate 2 and header board 1, described output main shaft 6 is provided with pressing connecting lever 61, described installation shaft 8 is provided with separating brake sincere sub 9, described separating brake sincere sub 9 comprises briquetting 91 and guide vane end stop 92, described briquetting 91 has the first state being pressed connecting lever 61 and pressing, pressing guide vane end stop 92 makes the second state of guide vane end stop 92 and separating brake semiaxis 7 phase card, briquetting 91 rotate make to press connecting lever 61 when reversing after the spacing third state and separating brake separating brake sincere sub 9 reset and make briquetting 91 unlock the 4th state of (unblock refers to and removes the briquetting third state to pressing the spacing of connecting lever) with pressing connecting lever 61.Specifically, certain angle is provided with between described briquetting 91 and guide vane end stop 92, when pressing connecting lever 61 and pressing briquetting, briquetting rotate certain angle drive again guide vane end stop rotate and the most at last guide vane end stop be pressed in the groove of separating brake semiaxis, realize separating brake half shaft locking, now briquetting is in the second state, now presses connecting lever and continues to rotate clockwise.Briquetting 91 turns an angle under the drive of reduction torsion spring 95, (pressing connecting lever rotates forward pressing connecting lever and refers to press briquetting clockwise in pressing connecting lever reversion after combined floodgate completes, make briquetting action, referring to accompanying drawing 3, the reversion of pressing connecting lever refers to press connecting lever and is rotated counterclockwise) time to be pressed the connecting lever limiting section 912 of block spacing, briquetting is in the third state; During separating brake, the action of separating brake semiaxis, make the de-card of the guide vane end stop on the sincere son of separating brake, the one end be located in installation shaft is stuck on jointed shaft and (does not provide in figure), torsion spring power drives jointed shaft to rotate clockwise (referring to Fig. 4), jointed shaft drives mounting panel, guide vane end stop and briquetting to rotate, now briquetting is to the spacing unblock of pressing connecting lever, now briquetting is in the 4th state, pressing connecting lever is rotated counterclockwise and makes to export main shaft reset, and briquetting is also driven by jointed shaft and resets to the first state completely.The beneficial effects of the utility model are, are provided with briquetting and guide vane end stop, make the pressing connecting lever energy secure pressed briquetting exporting main shaft, make briquetting drive guide vane end stop to move reliably and guide vane end stop is reliably blocked mutually with separating brake semiaxis; Guide vane end stop, owing to making to form certain angle between briquetting and guide vane end stop, through the transmission of exertin, is buckled in and separating brake semiaxis realizes separating brake puts in place by the utility model reliably, reliable and stable.And the utility model also has structure simply, easy for installation, the advantages such as space utilization is reasonable, the mechanical endurance of mechanism is long, can be reached for 5000-10000 time, make this product mechanical property have safe, reliable, stable characteristic, this kind of structure reaches technical requirement completely through checking.
