Check arc 411 and the gear teeth 412 are provided on the neighboring of driving wheel 41.Correspondingly, the outer periphery of driven wheel 42
Check arc 421 and the gear teeth 422 are provided on edge.When the check arc 421 on the check arc 411 and driven wheel 42 of driving wheel 41 matches
When conjunction, driven wheel 42 stops operating, and is locked in designated position, and driving wheel 41 continues to rotate, when driving wheel 41 the gear teeth 412 with
When the gear teeth 422 of driven wheel 42 are meshed, driving wheel 41 drives driven wheel 42 to rotate.
It is arranged at intervals with three sections of check arcs 421 on driven wheel 42, corresponds respectively to closing position, the isolation of three-station
Position and earthing position.The gear teeth 422 are set between wantonly two sections of check arcs 421.One section of 411 He of check arc is provided on driving wheel 41
One section of gear teeth 412.The arc length of the gear teeth is laid on driven wheel 42 and the arc length of the gear teeth is laid on driving wheel 41 according to driven wheel
42 run duration and depending on idle hours.Specifically, when processing the driven wheel 42 and driving wheel 41, first according to driven wheel 42
Run duration and idle hours, process the gear teeth being meshed on driving wheel 41 and driven wheel 42, then rest part is added
Work is check arc.
The radius of driven wheel 42 is greater than the radius of driving wheel 41.The arc length that driving wheel 41 is laid with the gear teeth 412 is driven wheel
The 1/6 of 41 circumferences, so that every 360 degree of the rotation of driving wheel 41, drives driven wheel 42 to rotate 60 degree.
In conjunction with shown in Fig. 6 to Fig. 8, Fig. 6 to Fig. 8 respectively illustrate three-station be in isolated location, closing position and
When earthing position, the structural schematic diagram that the driven wheel and driving wheel of operating mechanism match, when driving wheel 41 drives driven wheel 42
When turning to the position of check arc 421 of driven wheel 42, driven wheel 42 stops, the check arc 411 and driven wheel 41 of driving wheel 41
Check arc cooperate lock, so that driven wheel 41 is rested in designated position, three-station driven reliably to be maintained at closing position
It sets, at isolated location and the corresponding operating position of earthing position.
The shape of the check arc 411 of driving wheel 41 is similar to the circumferential profile of the driving wheel 41, the check arc of driven wheel 42
421 are recessed to the central axis direction of driven wheel 42, so that the check arc 411 of the protrusion of driving wheel 41 just falls into driven wheel 42
In the check arc 421 of recess, cooperation is realized.
Specifically, as shown in fig. 6, three-station is in isolated location, first check arc 421a of driven wheel 41 with
The check arc 411 of driving wheel 41 matches, and three stations are gone into operation and are locked in isolated location, i.e., the movable contact of three-station with connect
Ground contact, stationary contact isolation.Driving wheel 41 continues to rotate, and the gear teeth 412 to driving wheel 41 turn to the gear teeth with driven wheel 42
422 when being meshed, and driven wheel 42 rotates again.It is driven when driven wheel 42 turns to second check arc 421b shown in Fig. 7
Wheel 42 stops, and the check arc 411 of second check arc 421b of driven wheel 41 and driving wheel 41 cooperates, driven wheel 42 this
It is lockked at two check arc 421b, the movable contact for making three stations go into operation is maintained at closing position.Motor 10 inverts, 41 band of driving wheel
Dynamic driven wheel 42 inverts, when the check arc 411 of driving wheel 41 cooperates with first check arc 421a of driven wheel 42 again, three
The movable contact that station goes into operation stops at isolated location again.Driving wheel 41 continues to rotate, and the gear teeth 412 to driving wheel 41 rotate
To when being meshed with the gear teeth 422 of driven wheel 42, driven wheel 42 rotates again, when driven wheel 42 turns to third shown in Fig. 8
When a check arc 421c, driven wheel 42 stops, 411 phase of check arc of the third check arc 421c and driving wheel 41 of driven wheel 41
Cooperation, driven wheel 42 position latching at third check arc 421c, and the movable contact for making three stations go into operation is maintained at ground connection position
It sets.
Due to driven wheel 42 three check arcs correspond to three-station three operating positions (that is, closing position, every
Off normal set and earthing position), and correspond to isolated location first check arc 412a setting another two check arc centre,
Therefore, no matter three-station is to be in closing position in earthing position, be both needed to switch by isolated location
To earthing position or closing position, therefore, the case where three stations can be effectively prevent to occur two-by-two while connecting, good reliability,
Maloperation can be prevented, mechanical interlocking is realized from structure.
Further, the front end of worm screw 31 is provided with axis and stretches 33.The axis stretches 33 for six square shafts, when 10 no power of motor, leads to
Crossing operation handle drives worm screw 31 to rotate, and can be realized and manually controls.
Further, finite place piece 43 is installed, specifically, the locating part 43 is mounted on first check arc on driven wheel 42
At 421a.As shown in connection with fig. 1, it is provided with limiting slot 1011 on upper mounting plate 101, the head end of the locating part 43 is located at the limiting slot
In 1011, and the locating part 43 slides in limiting slot 1011 with the rotation of driven wheel 42.The shape of the limiting slot 1011 with
The sliding trace of the locating part 43 is adapted.Specifically, the limiting slot 1011 is in crescent shape.Specifically, the locating part 43 can be with
Bolt or screw.
In addition, locating part 43 is also mountable at second check arc 421b or third check arc 421c, upper mounting plate
The position of 101 upper limit position grooves also changes according to the installation site of locating part 43.
By the setting of limiting slot 1011 and locating part 43, manual maloperation can be prevented.
