A kind of position holding mechanism provided by the utility model, including electromagnet 1, fixing seat 2, the first auxiliary axis 3, spring 4,
Second auxiliary axis 5, the first locking bar 6, the second locking bar 7, the auxiliary axis 8 of third, first connecting rod 9, first gear 10, second gear 11, main shaft
12, second connecting rod 13, third connecting rod 14, moving contact 15.
As shown in Figure 1, a kind of position holding mechanism provided by the utility model is in closing position, which crosses dead point guarantor
It holds, does not need the first locking bar 6 and the second locking bar 7 works.Fixing seat 2 is fixed to the earth, and the second locking bar 7 passes through the first auxiliary axis 3
Hinged with fixing seat 2, one end of the first locking bar 6 is hinged on fixing seat 2 by the second auxiliary axis 5, and the other end can by the auxiliary axis 8 of third
With in the sliding slot slide inside of the second locking bar 7, one end of spring 4 is fixed on the first auxiliary axis 3, the other end is fixed on the auxiliary axis 8 of third.
Due to the effect of spring tension, so that locking bar 8, locking bar 9 and fixing seat 11 are maintained at state shown in FIG. 1.It keeps in the position
When mechanism is in closing position, the first locking bar 6, the second locking bar 7 works not yet, the first locking bar 6,7 He of the second locking bar
Being connected under the action of 4 pulling force of spring in position shown in FIG. 1 between fixing seat 2.In Fig. 1, spring 4 connected
Three auxiliary axis 8 are in inside the sliding slot of the second locking bar 7 near the side of the first auxiliary axis 3, and the pulling force of spring 4 makes the first locking bar 6,
The triangle constituted between second locking bar 7 and fixing seat 2 is in stable state.
One end of first connecting rod 9 is connect with electromagnet 1, and the other end is attached with first gear 10, and connection type is all
Hingedly.Electromagnet 1 moves up, and can generate upward impetus, first gear 10 to first gear 10 by first connecting rod 9
Under the action of upwards thrust, it can be rotated counterclockwise around the central axis of first gear 10；Electromagnet 1 moves down, and can lead to
It crosses first connecting rod 9 and generates downward pulling function to first gear 10, first gear 10 can surround under the action of downward pulling force
The central axis of first gear 10 does clockwise rotation.The position holding mechanism further includes second gear 11, and main shaft 12, second connects
Bar 13, third connecting rod 14 and moving contact 15.Second gear 11 is engaged with first gear 10, and the rotation of first gear 10 can drive
The rotation of two gears 11, the rotation of second gear 11 and the rotation of meeting driving spindle 12, the rotation of main shaft 12 can pass through second and connect
Bar 13, the effect of third connecting rod 14 drive the open or close of moving contact 15, carry out between second connecting rod 13 and third connecting rod 14
Hingedly, third connecting rod 14 and moving contact 15 also carry out hingedly.In the position shown in the figure 1, the position of electromagnet 1 is in bottom,
There are no moving up, moving contact 15 is also in closed position at this time.
When electromagnet 1 moves up, electromagnet 1 pushes first gear 10 counterclockwise by the first connecting rod 9 hinged with it
Rotation, first gear 10 are engaged with second gear 11, and driving spindle 12 rotates clockwise, and passes through second connecting rod 13, third connecting rod
14 effect drives moving contact 15 to open.When electromagnet 1 continues upward movement, the opening amplitude of moving contact 15 will drive increasingly
Greatly, as shown in Fig. 2, being when the driving of electromagnet 1 first gear 10 touches the position of the first locking bar 6.It is contacted in first gear 10
To after the first locking bar 6, electromagnet 1 is continued to move up, and first gear 10 will push the second locking bar 7 and continue up.The
The force analysis of one locking bar 6 is as shown in Fig. 2, thrust F9 will push the first locking bar 6 rotates clockwise, the size of thrust F9, can be with
As needed, it is adjusted by the size of change 7 upper hopper chute position of the second locking bar and the power of spring 4.With first gear
10 continuous movement, the second locking bar 7, which will be pushed completely, reaches extreme position, as shown in Figure 3.Behind the position, spring 4 is logical
It crosses the auxiliary axis 8 of third and pulls the first rotation counterclockwise of locking bar 6, the auxiliary axis 8 of third is in the sliding slot of the second locking bar 7 to close to the first auxiliary axis
3 direction movement, is eventually returned to initial position shown in FIG. 1.As shown in figure 4, moving contact 15 is in an open position at this time, touching is moved
First 15 under gravity, drop down, but the side due to the second locking bar 7 far from the first auxiliary axis 3 is the inclined-plane with angle,
The inclined-plane can stop first gear 10 to rotate, so that moving contact 15 be made reliably to be maintained at open position.When needing closing operation,
Give first gear 10 sufficiently large driving force, it can the second locking bar 7 of driving rotates clockwise, so that the second locking bar 7 is oblique
Face stops to disappear, and realizes the combined floodgate of moving contact 15.Opening described in similar Fig. 2 of stress condition of first locking bar 6 and the second locking bar 7
Process.The size of combined floodgate driving force can also by adjusting the second locking bar 7 bevel angle, change 7 upper hopper chute position of the second locking bar
It sets and is adjusted with the size of the power of spring 4.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that this field ordinary skill without
It needs creative work according to the present utility model can conceive and makes many modifications and variations.Therefore, it is all in the art
Technical staff passes through logical analysis, reasoning, or a limited experiment according to the design of the utility model on the basis of existing technology can
It, all should be within the scope of protection determined by the claims with obtained technical solution.
