Embodiment
Fig. 1 to Fig. 5, the operating mechanism of driving mechanism for switch according to an embodiment of the invention is shown, the operation
Mechanism includes driver 2, driver runner 11 and the spring assembly device 13 being assemblied in framework 1.
Framework 1, driver 2 and spring assembly device（13、21）Deng driver（2）Not only there is I (combined floodgate) position, O
(separating brake) position, also has II (idle stroke) position, and I positions and II positions can be respectively relative to O positions, in the opposite direction into predetermined
Angle (αI、αII) positioning.
Driver 2 can be in the hole of framework（20）Middle rotation, and drive the driving runner 11 above driver 2 together to revolve
Turn, all clampings of first end support base 14 of spring assembly device 13 on framework 1, the second end 6 in spring assembly device 13 and
Spring 8 can be on support base 14 the boss 23 with arc-shaped surface rotate.
The driving mechanism for switch has O positions, I positions and II positions, and at O positions and II positions, switching device (does not show
Go out) pole be open, be in the pole of I position switch devices closure.
In complete driving mechanism for switch, operation handle (not shown) is secured on driver 2, with rotation driving
Device 2.
In Fig. 1, driver 2 is in O positions, and at this moment spring assembly device 13 and 21 is substantially all in resting position,
Second end breach 4 of each spring assembly device 13 is in free engagement with cylinder 7 and 9 on runner 11.
Driver（2）On runner（11）There are two cylinders in setting（7 and 9）, this two cylinders（7 and 9）With with
Carry out the spring assembly device of rotating driver（13）On breach（4、10）Engageable or separation.
In fig. 2, driver 2 and runner 11 above turn clockwise some angle relative to O positions to I positions
βIWhen, the spring 8 in spring assembly device 13 is compressed and rotated simultaneously around the convex platform 23 of support base 14 with the second end 6, each
Breach 4 and 10 on second end of spring assembly device, the pressure with the cylinder 7 and 9 on runner 11 by spring 8 and 22, tightly
Close engagement.
At driver during position between O and I, the breach on each spring assembly device（4）All the time with driver（2）On
Cylinder（7 and 9）It is meshed, works as driver（2）During in O and II positions, breach（4）All the time with cylinder（7、9）Phase point
From.
Each spring assembly device（13）First end（14）Framework can be pivotally supported（1）On.
With runner 11 continuation clockwise from O positions to I positions rotate, relative to O positions to more than 45 ° when, spring 8
After being compressed to minimum length with 22, the elastic force of spring 8 and 22 is released, then because the elastic force that spring 8 and 22 discharges continues
Promote runner 11 to rotate, rotate to I positions always, i.e., have rotated α relative to O positionsIAngle, α in present caseIFor 90 °, now
Spring force substantially discharged to the greatest extent, and the second end breach 4 of spring assembly device 13 and with the cylinder 7 and 9 on runner 11 again
In free engagement.
In figure 3, driver 2 and runner 11 are all located at I positions.When driver 2 and runner 11 start from Fig. 3 I positions
During rotate counterclockwise, spring 8 and 22 starts to be compressed, and continues to rotate counterclockwise to relative to I with driver 2 and runner 11
When position is more than 45 °, after spring 8 and 22 is compressed to minimum length, the elastic force of spring 8 and 22 is released, then because of the He of spring 8
22 elastic force gone out continue to press on runner 11 and rotated, and rotate to O positions always, and now, elastic force has substantially discharged to the greatest extent, spring assembly
The second end breach 4 and 10 on device 13, free engagement is in again with the cylinder 7 and 9 on runner 11.Now, drive
Relative position between the runner 11 of device 2 and spring assembly device 13 is returned to the state of Fig. 1 signals.
When driver 2 and runner 11 continue by O positions rotate counterclockwise, i.e., when being rotated counterclockwise towards II positions by O positions,
Cylinder 7 and 9 on runner 11 departs from the second end breach 4 and 10 on spring assembly device 13.Illustrated in Figure 4 is when drive
Dynamic device 2 and runner 11 are relative to O positions to one some angle beta of II positions rotate counterclockwiseIIWhen, driver 2 and runner 11 with
Relative position between spring assembly device 13.In the process that driver 2 and runner 11 are rotated towards II positions counterclockwise by O positions
In, the non-return plane 18 on the II positions pushing block 17 of the bottom of driver 2 contacts with the boss 5 on main shaft 19, and is always maintained at
Contact, to prevent main shaft 19 from turning round, is shown in that Fig. 5 illustrates until II positions.
The lower part of driver 2 also sets up I positions and transmits block（16）Block is transmitted with II positions（17）, block is transmitted in wherein II positions
（17）Upper surface sets non-return plane（18）, block is transmitted in I positions（16）Block is transmitted with II positions（17）It can distinguish in different time
Pass through the boss on main shaft (19)（5）By driver（2）Rotational energy pass to main shaft（19）.
When Fig. 6 illustrates that driver 2 and runner 11 continue to rotate counterclockwise to II positions by O positions, i.e., relative to O positions
Put rotate counterclockwise αIIAngle, in de- between breach 4 and 10 on the cylinder 7 and 9 and spring assembly device 13 on runner 11
From the statement of state.α in present caseIIFor 90 °.When driver 2 and runner 11 reach II positions, limit of the driver 2 by framework 1
Position restricts, it is impossible to is further continued for rotating counterclockwise (not shown).
When between O and II positions at driver 2, not only breach 4 all the time with cylinder（7、9）It is separated, and II positions
Transmit block（17）On non-return plane（18）All the time with main shaft（19）On boss（5）It is in contact, to prevent main shaft 19 from rotating.
Fig. 7 is the structural representation of spring assembly device 13.
Fig. 8 is the schematic diagram of one embodiment after driving mechanism for switch of the present invention decomposes.
Fig. 9 be it is of the present invention beginning combination of drive means after one embodiment schematic diagram.
The basic thought of the present invention can realize that therefore, the present invention and its embodiment are not restricted in many ways
Above-mentioned example, but can be changed within the scope of the claims.
