Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
Energy storage electric operatnig device as shown in figures 1-4, comprise support 1, cam 2, energy storing members 3, lever 4, locking board 5 and rotating shaft 12, the fulcrum of lever 4 is articulated with support 1, one end of lever 4 and one end of energy storing members 3 hinged, the other end and the support 1 of energy storing members 3 are hinged, the other end of lever 4 is used as the output 41 driving breaker actuation, and be provided with the roller 6 coordinated that to roll with cam 2 between the fulcrum of lever 4 and the other end of lever 4, cam 2 is articulated with support 1 through a drive shaft 13; One end of locking board 5 is articulated with support 1 and coaxial with drive shaft 13, the other end of locking board 5 is connected with support 1 elasticity, and the other end of this locking board 5 is provided with the engaging portion 52 fastened with rotating shaft 12, rotating shaft 12 is articulated with support 1, and rotating shaft 12 is provided with the catching groove 121 be fastened with this engaging portion 52, locking board 5 also has the rolling auxiliary section 51 coordinated of rolling with roller 6.
Moving cam 2 is with to rotate by drive shaft 13, order about roller 6 by the rotation of this cam 2 to rotate, thus drive lever 4 relative to cam 2 reverse rotation, now, the rolling auxiliary section 51 of locking board 5 will depart from the cooperation of roller 6, thus makes locking board 5 under elastic force, depart from the fastening with rotating shaft 12, now, energy storing members 3 is by compressed energy-storage under lever 4 drives, and the output 41 of lever 4 also will drive the handle 11 of circuit breaker to make feed motion; When rotation rotating shaft 12, and after engaging portion 52 and catching groove 121 are fastened, moving cam 2 is with to reverse by drive shaft 13, roller 6 can coordinate with rolling auxiliary section 51, and coordinate with lever 4, thus lever 4 is resetted, and then drive energy storing members 3 to discharge, the output 41 of lever 4 also pulls work again by driving the handle 11 of short-circuiting device to make; As fully visible, the present invention just completes energy storage and output 41 output action by the cooperation of roller 6, cam 2, lever 4, therefore low to the consistency of parts such as cam 2 grade, required precision, structure is simpler, and cost is cheaper, when roller 6 is rolled into cam peak, locking board 5 fastens, and now whether cam continues to be driven in rotation, and locking board all can not depart from the rotating shaft with catching groove, parked position wider range of cam is general, relaxes the final parked position of cam.
For carrying out spacing to the rotary oscillation of lever 4, support 1 is provided with limited post 7, and one end of lever 4 is provided with the stopper slot 42 supported with limited post 7 and coordinate.
Dodging space for being formed, avoiding to make the actuating force of drive shaft 13 interfering, between the indication of lever 4 and the other end of lever 4, having the deep-slotted chip breaker 43 passed for drive shaft 13.
As a preferred structure of energy storing members 3 of the present invention, energy storing members 3 comprises energy-stored spring 31, joint pin 32 and sleeve 33, one end of sleeve 33 and one end of lever 4 hinged, the other end slip cap of sleeve 33 is loaded on one end of joint pin 32, the other end and the support 1 of joint pin 32 are hinged, energy-stored spring 31 is set in joint pin 32 and sleeve 33, and one end of this energy-stored spring 31 is supported mutually with one end of sleeve 33, and the other end of this energy-stored spring 31 is supported mutually with the other end of joint pin 32.When the stressed extruding energy storing members 3 of lever 4, sleeve 33 is inserted in joint pin 32, and energy-stored spring 31 is extruded energy storage, otherwise sleeve 33 is overhanging from joint pin 32, and energy-stored spring 31 discharges.
Coordinate for being formed to roll with roller 6 better, as shown in Figure 4, rolling auxiliary section 51 is for being opened in the inside groove on locking board 5.Maintain the stable of action during the effect of locking board 5, prevent lever 4 from arbitrarily swinging.
As one preferred embodiment, for providing enough elastic forces, guaranteeing the limited action of the elasticity of locking board 5, as shown in Fig. 1 ~ 2, the support 1 of this example being fixed with steady pin 8, the other end of locking board 5 is connected with steady pin 8 elasticity by an extension spring 9.
Link for being formed with the handle 11 of circuit breaker better, the output 41 of the lever 4 of this example is hinged with a set of ring stand 10, and cover ring stand 10 can be set with the handle 11 of circuit breaker better and links, more reliably to realize detaining again, to close a floodgate, the action of separating brake.
Snap close and unblock effect are played in the action that the output 41 of lever 4 exports, and during snap close, make lever 4 under its supporting role, maintain the energy storage state of lever 4 under energy storing members 3 acts on; During unblock, only need less external force to rotate rotating shaft 12, just can complete unlocking motion.
Specifically, rotate counterclockwise under the outside rotary driving force effect of cam 2, as shown in Figure 2, roller 6 tangent with it on lever 4 is rolled, thus lever 4 take fulcrum as pivot turns clockwise, and driving cover ring stand 10 (divide-shut brake assembly) toward left movement by output 41, this Sports band moves circuit breaker handle 11 and pulls work again, and lever 4 compressed energy-storage spring 31 carries out energy storage simultaneously.When lever 4 clockwise movement, because roller 6 will depart from and the coordinating of rolling auxiliary section 51, then locking board 5 does clockwise movement around himself pivot under extension spring 9 acts on, when rotating to peak to make cam 2, circuit breaker is detained again, and energy-stored spring 31 completes energy storage, after energy storage, engaging portion 52 can be buckled into catching groove 121, remain stable, so far mechanism completes energy storage and pulls work again.
As shown in Figure 1, when rotating shaft 12 under external force, after the motion of himself pivot, engaging portion 52 can fall into catching groove 121 and fasten with it, now lever 4 balance support is broken, and counterclockwise movement is done under the elastic force of energy-stored spring 31, the cover ring stand 10 (divide-shut brake assembly) that lever 4 promotes output 41 is turned right motion, and this Sports band moves circuit breaker handle 11 and carries out feed motion.When lever 4 move to stopper slot 42 contact with limited post 7 time, energy-stored spring 31 discharges completely, circuit breaker rapid closing.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the claims in the present invention.
