Embodiment
Combine accompanying drawing, the utility model that with the model is WJCT20WA is an example at present, and the utility model and model are that the vacuum circuit-breaker of ZW20 is complementary, and its structure is further described with making to be used as.Like Fig. 1, shown in Figure 2; This spring operating mechanism comprises header board, back plate, takes along son, cam, separating brake release, combined floodgate release, overcurrent release, binding post, switching-in spring, energy storage motor and gear shaft, and hand-power energy storage axle 2, energy storage reduction torsion spring 5, soldered tooth 6, back-moving spring 7, combined floodgate semiaxis torsion spring 8, backing pin 39, combined floodgate semiaxis 10, release lever 11, dropout connecting lever 12, manually close split axle 14, drive connecting lever 15, extension spring 18, separating brake semiaxis torsion spring 22, pivot pin 23, separating brake dropout plate 24, separating brake semiaxis 25, backing pin 4 16, backing pin 5 20, spacer pin 1, spacer pin 2 17, finger 1 and finger 2 21.Gear shaft one end of this spring operating mechanism inserts in the hand-power energy storage axis hole, and two parts are free to rotate; One end of back-moving spring withstands on the gear face on the gear shaft, and the other end withstands on the soldered tooth; Soldered tooth is sleeved on the gear shaft.Under the effect of back-moving spring, soldered tooth moves outside the gear shaft axial direction, the flank engagement of the flank of tooth of soldered tooth and hand-power energy storage axle; The radial direction of soldered tooth is provided with keyway, and the key of radial arrangement matches on this keyway and the gear shaft, and transmits the power of radial direction.Because the tooth of soldered tooth is counterclockwise pawl, can only transmit power counterclockwise, pawl contacts with the tooth inclined-plane in the time of clockwise, does not transmit power.Spacer pin one is contained on the hand-power energy storage axle, and spacer pin one plays position-limiting action when the hand-power energy storage with backing pin 1, backing pin 24; Hand-power energy storage axle action counterclockwise once can reset to initial position in the back under 5 effects of energy storage back-moving spring.
The hand-power stored energy operation mode of this spring operating mechanism is following: firmly hand-power energy storage axle is rotated along counter clockwise direction; Spacer pin one is blocked by backing pin two; Because pawl on the soldered tooth and the engagement of the tooth on the hand-power energy storage axle; Thereby soldered tooth has also rotated certain angle, and soldered tooth turns an angle through key driven gear axle again; Unclamp hand then, hand-power energy storage axle resets to position at the beginning along clockwise direction under the energy storage action of reset spring; Hand-power energy storage axle is in reseting procedure, and the pawl chamfered portion effect of the chamfered portion of energy storage shaft head tooth and soldered tooth is separated thereby soldered tooth is moved the tooth that makes on soldered tooth and the hand-power energy storage axle to gear shaft flank of tooth direction; Back-moving spring is compressed.When hand-power energy storage axle reset to initial position, hand-power energy storage axle stopped operating, soldered tooth reset to again under the effect of back-moving spring with hand-power energy storage axle on the state that is meshed of tooth, and then get ready for energy storage next time.Repeat above hand-power thermal energy storage process and can carry out stored energy operation entire mechanism.Owing to be that gear shaft is directly operated, operate more reliable than the mode of operation of existing like product, lighter.
The hand branch of this spring operating mechanism, hand closing operation part are directly arranged the semiaxis head in the clamping plate outside; Be used for partially overlapping of branch, combined floodgate tripping coil top, the structure of dropout connecting lever, separating brake dropout plate is much smaller than existing like product to the semiaxis intensity effect.Simultaneously, finger one, finger two through welding manner with drive connecting lever and weld together, drive connecting lever again through flat key with manually close split axle and be solidly installed.Its hand branch, hand closing operation mode are following: manually close the split axle certain angle as long as rotate counterclockwise; Finger two just can drive the separating brake dropout plate on the separating brake semiaxis; Thereby can realize sub-switching operation, stop to drive when manually closing split axle, manually close split axle and under the extension spring effect, can reset.The closing by hand operation; Only need clockwise driving manually close the split axle certain angle, finger be once can driving the driving connecting lever that is contained on the combined floodgate semiaxis, thereby can realize closing operation; Stop to drive when manually closing split axle, manually close split axle and can under the extension spring effect, reset to position at the beginning again.
The utility model is because volume is little, and only there is the breach of 165 * 60mm in the upper right side of clamping plate, and is unaffected fully for the mounting or dismounting of mechanism on switch.In sum, the utility model is no matter on structure, and is or all advanced, reliable, practical than the mechanism of existing like product on the performance.
