311 increase the contact surface between the position-limited wheel 4, make the right limit item 21 and the left limit item 31 in malfunction
It being easier to be blocked, two of automatic change-over switches are not in close a floodgate simultaneously or the case where unexpected separating brake powers off,
Improve the reliability of automatic change-over.
As shown in Figure 1, the notch section 41 is sector structure, is on one side the center of circle of the position-limited wheel 4 to the right circle
211 inside endpoint of arc slot, another side are the center of circle of the position-limited wheel 4 to the left 311 inside endpoint of arc groove, the limit
It so that the notch section 41 is directed at the positive stop strip of rotary side when 4 rotation of wheel, relieve the blocking to transmission mechanism, driver
Structure can be simple and reliable for structure with the mobile closure switch of the driving wheel 1.
In order to limit the rotation angle of the position-limited wheel 4 spend greatly switch close a floodgate after can also continue to rotate, such as Fig. 2-3 institute
Show, the corresponding notch section 41 of the position-limited wheel 4 is equipped with retention bead 42 in the other side, and the retention bead 41 is located at described
On the extension line of 42 middle line of notch section., while the retention bead 42 side transmission bracket switch close a floodgate when, to the other side
Transmission bracket applies fastening force so that it will not malfunction, and improves the reliability of automatic change-over.
As a kind of preferred embodiment, the notch section 41 of the corresponding position-limited wheel 4 of the driving wheel 1 be equipped with it is described
3 meshed gears area 11 of right transmission mechanism 2 and the Left Drive mechanism, guarantees to be directed toward the transmission mechanism in the notch section 41
Afterwards, the driving wheel 1 just drives the transmission mechanism is mobile switch is made to close a floodgate, and ensure that the reliability of interlocking mechanism.
As a kind of preferred embodiment, the center of circle of the driving wheel 1 is equipped with the handle hole 12 being fitted into for motor shaft, institute
Rotation can be controlled by motor by stating driving wheel 1, realize the function of automatic transfer switch.
As a kind of preferred embodiment, operating mechanism is additionally provided with the manual gear 5 with the driving wheel 1 coaxial arrangement.
Further, operation handle 51 is equipped on automatic change-over shell, one end of the operation handle 51 is provided with
With the arc-shaped gear area 52 of the manual gear 5 cooperation linkage.
The rotation that the driving wheel 1 is driven by the mutual cooperation in the manual gear 5 and the arc-shaped gear area 52, is used
Handle is easy to operate, achieves that manual switch without tool, time saving and energy saving.
As a kind of preferred embodiment, the manual gear 5 and the driving wheel 1 and the position-limited wheel 4 be one at
Type, integrated formed structure facilitates the synchronous rotation between gear, guarantees the reliability of interlocking gear.
It is illustrated below with reference to working principle of the Fig. 1-2 to the operating mechanism of the automatic change-over of the present embodiment:
As shown in Figure 1 when the driving wheel 1 is in intermediate state, the notch section 41 of the position-limited wheel 4 is directed toward the right side
