Power end 5.Simultaneously because the resigning effect of driving stage clip 20, first connecting rod 24 can be turned over by the central shaft of operation rotating shaft 31
The central axis of line, the central axis of the second bearing pin 27 and the 3rd bearing pin 28 forms dead point when being in same plane, is further continued for turning
A low-angle is crossed, is limited until the spacing preiection 331 of the arc surface one end of reversing plate 33 coordinates on gag lever post 34, the
One connecting rod 24 has the trend rotated counterclockwise, prevents the opposite direction of first connecting rod 24 is rotated clockwise from depart from moving contact 21
Static contact 22, possesses auto-lock function.Now, operation rotating shaft 31 also drives driving lever 311 to touch the one of the close conventional side of power end 5
Group the first microswitch 39 contact powers off the magnet coil 32 close to the conventional side of power end 5.After magnet coil 32 is powered off, change
Resetted to the driving of reseting pressuring spring 321 dynamic iron core 322 of mechanism 3, first extension spring 38 drives the drive pin 37 to coordinate one
To position the reversing plate 33 and the operation rotating shaft 31 on individual locating slot 334, while the second extension spring 3a is also by the driving lever
311 hold operation rotating shaft 31, further to lock the reversing plate 33 and the operation rotating shaft 31.In this state, as schemed
Shown in 15, operation rotating shaft 31 drives the linkage crank 30 close to the conventional side of power end 5 to rotate counterclockwise simultaneously, blocking lever 302
The high order end of upper strip through hole 303 is leaned against on the 4th bearing pin 301, to limit the contact mechanism 2 close to standby electricity source 6
Close a floodgate.Because the contact mechanism 2 close to standby electricity source 6 will such as close a floodgate, it is necessary to turn the operation close to the side of standby electricity source 6
Axle 31 is rotated clockwise, and now necessarily drives the operation rotating shaft 31 close to the conventional side of power end 5 clockwise by blocking lever 302
Rotate, make close to the separating brake of 5 side contact mechanism of conventional power end 2, therefore realization is coordinated by the crank 30 that links, blocking lever 302
Interlocking so that conventional power end 5 and the contact mechanism 2 of standby electricity source 6 can not close a floodgate simultaneously.
As shown in figure 16, the 2-in-1 lock of contact mechanism close to standby electricity source 6 makes standby electricity source 6 electrically connect load end 4
When, close to the inevitable separating brake of the contact mechanism 2 of conventional power end 5, conventional power end 5 disconnects with load end 4.Changed with preferable improve
Switch the security used.
It the above is only one preferred embodiment of the utility model, those skilled in the art makees equivalent by claim
Change the protection domain for both falling within this case.
