End there is connecting hole respectively, drivening piece 322 is connected on the two connecting holes.Therefore, drivening piece 322 is formed positioned at crank
Groove 321a for the axis body that mounts of opening 312a phases with hook 312.
As shown in Fig. 1 and Fig. 6, Fig. 7, hook 312 also includes the first side 312b and the second side 312c, and elastic component 330 is compressed
First side 312b of hook 312 is so that the second side 312c is pressed on the crank pit 321a of crank axle 321.The first of hook 312
Side 312b is in arc line shaped, and the 312a that is open is positioned at the middle part of the second side 312c.
Wherein, the second side 312c of hook 312 has the first pressure section 312c1 and the second pressure section 312c2, and first compresses
, on opening 312a, the second pressure section 312c2 is under opening 312a for portion 312c1.It is preferred that the first of hook 312
, in inner circle arc, the second pressure section 312c2 is linear for pressure section 312c1.
Before the opening 312a that drivening piece 322 enters hook 312, i.e., before drivening piece 322 is mutually mounted with hook 312,
First pressure section 312c1 is pressed on crank axle 321.Drivening piece 322 turns to closing position by 312 band fixed handle 311 of hook
Postpone, the second pressure section 312c2 is pressed on crank axle 321, drivening piece 322 departs from the opening 312a of hook 312.
The component 320 that is connected also includes gear 323 and gear shaft 324, and gear 323 is connected on gear shaft 324, crank
Axle 321 is connected on gear 323, and drive component drive gear 323 is rotated, so as to gear 323 drives crank axle 321 and gear
Axle 324 is rotated.Wherein, crank axle 321 is coaxial with gear 323 and mode that can rivet is connected, and other connections may also be employed certainly
Mode.
Separately, as shown in figures 1 to 6, Handleset 310 also includes rib axle 314, and handle 311 is with transversal with rib axle 314
The rib axis hole 311a that face is adapted, rib axis hole 311a of the rib axle 314 through handle 311, by drive lip axle when handle 311 is rotated
314 coaxial rotating in same direction.In the present embodiment, rib axle 314 is Axis Tripod, and the centre of handle 311 is in triangular shape, with triangle
Axle coordinates.Rib axle 314 and rib axis hole 311a can also adopt other non-rotating shapes.
To sum up, the handle of miniature circuit breaker of the present utility model be connected component 300 the course of work it is as follows：
As shown in Figure 1, Figure 2 and Figure 3, gear 323 is engaged with the power gear of the drive component of miniature circuit breaker, now,
Elastic component 330 is pressed on the first pressure section 312c1 for linking up with 312 on the crank pit 321a of crank axle 321.Hook 312 turn
The rotational axis x 2 of shaft line X1, the i.e. axial line of pin 313 less than handle 311, the rotational axis x 3 of crank axle 321 is less than extension
The rotational axis x 1 of hook 312, the opening 312a of hook 312 are less than the rotational axis x 3 of crank axle 321, crank axle 321, hook
312nd, pin 313 and elastic component 330 be in the same plane.
The power teeth wheeling driving gear 323 of miniature circuit breaker is rotated clockwise, and gear 323 drives crank axle 321 clockwise
Rotate, crank axle 321 rotates clockwise certain angle.As shown in Figure 4 and Figure 5, the drivening piece 322 on crank axle axle 321 and extension
Hook 312 is mounted with opening 312a under the thrust of elastic component 330, and 312 stress of hook are moved up, and link up with 312 and pin
313 coordinate the band fixed handle 311 in the presence of thrust to rotate counterclockwise, and while handle 311 is rotated, drive lip axle 314 is rotated.
When hook 312 is moved a certain distance, when the axis of drivening piece 322 is higher than the rotational axis x 2 of handle 311, i.e., hook 312 is open
Rotational axis x 2 of the 312a higher than handle 311, the end of the second pressure section 312c2 of hook 312 is limited by crank axle 321 to be made
Drivening piece 322 departs from opening 312a, and now handle 311 reaches closing position, closing success.
Gear 323 drives crank axle 321 to be rotated further, and drivening piece 322 is separated with the opening 312a on hook 312.
The closing switch method of miniature circuit breaker of the present utility model is comprised the following steps：
S100, when initial, handle 311 is located at open position, and elastic component 330 is pressed on linking up with 312 on crank axle 321；
S200, after crank axle 321 is rotated so that drivening piece 322 is mounted with opening 312a phases, what crank axle 321 was rotated further
Drivening piece 322 drives simultaneously, and 312 band fixed handle 311 of hook turns to closing position；
S300, crank axle 321 is rotated makes drivening piece 322 depart from the opening 312a on hook 312.
In step S100, elastic component 330 is by the portion compresses on the opening 312a of hook 312 on crank axle 321；Step
In rapid S300, elastic component 330 is by the portion compresses under the opening 312a of hook 312 on crank axle 321.
Also include in step S100：The pivot center of the pivot center less than handle 311 of hook 312, before combined floodgate, is set, is opened
Pivot centers of the mouth 312a less than crank axle 321, the pivot center of crank axle 321 is less than the pivot center for linking up with 312.
In step S300, after combined floodgate, the pivot center for linking up with 312 is higher than the pivot center of handle 311, and the 312a that is open is higher than
The pivot center of crank axle 321.
During closing by hand, only need to shift handle 311 onto closing position manually.During automatic closing, due to power motor
In failure (or power failure) making process, stop suddenly, now can the arrival closing position of manual driving handle 311.
Stable transmission of the present utility model, you can adapt to closing by hand, be suitable for automatic closing again.In electric switch-on process
In do not affect closing by hand；After in-place closing, motor transmission part completely disengages from the relation that transmission is coupled with handle portion.
Certainly, this utility model can also have other various embodiments, spiritual and its essence without departing substantially from this utility model
In the case of, those of ordinary skill in the art work as and can make various corresponding changes and deformation, but these according to this utility model
Corresponding change and deformation should all belong to the scope of the claims appended by this utility model.
