It is scheduled in the space between the first block piece and the second block piece, moving contact is maintained at double point positions, as shown in Figure 2.
Then, when third electromagnet 27 is activated, the first block piece 12 and the second block piece 13 can be made from locking bit
It sets and switches to unlocked position, to release the locking to locking piece 11.In this embodiment, third electromagnet is via intermediary agency
(not shown) presses the both ends of the furthest apart of the first block piece 12 and the second block piece 13 (it is of course also possible to pull the first resistance
Block piece and the second block piece are separated by nearest both ends), to make the first block piece along rotation counterclockwise, the second block piece is along suitable
Hour hands rotate, as shown in figure 3, so that locking piece can continue to rotate out of the space between the first block piece and the second block piece,
Moving contact continues to rotate to be contacted with the static contact of second source, to reach second source on-position.At this point, third electromagnetism
Iron can fail, and the first block piece and the second block piece restore under the action of the first spring and second spring to first respectively
Beginning position.
Fig. 4 shows the schematic diagram of the locking mechanism of second embodiment according to the present utility model.The locking of second embodiment
The locking mechanism of mechanism and first embodiment the difference is that：In a second embodiment, the first electromagnet and the second electromagnetism
Tie Tong crosses belt transmission and realizes the rotation of centre wheel.Specifically, belt 28 surrounds centre wheel 25, and is connected to the first electromagnet
With the second electromagnet, centre wheel can be made accordingly to be rotated under the action of the first electromagnet and the second electromagnet.Second group
Fork is movably mounted in rack, and second one end even is rotatably installed in rack, and the other end is contained in the second shift fork
It is interior.The locking of the course of work of the locking mechanism of second embodiment in dual-power transfer switch and the first embodiment of Fig. 1-3
The course of work of mechanism is similar, and details are not described herein.
Fig. 5 shows the schematic diagram of the locking mechanism of 3rd embodiment according to the present utility model, and 6 show according to this practicality newly
The perspective view of the locking mechanism of the 3rd embodiment of type, Fig. 7 show the locking mechanism of 3rd embodiment according to the present utility model
Exploded view.Similar to the above embodiments referring to Fig. 5, dual-power transfer switch includes the first electromagnet for the first power supply
21 and for second source the second electromagnet 22.First electromagnet 21 and the second electromagnet 22 are respectively via bindiny mechanism in
Heart wheel 25 connects, centre wheel can be driven to rotate when being activated.Main shaft 31 is fixed together with centre wheel 25, makes
Obtaining the rotation of main shaft 31 can drive centre wheel 25 to rotate.
Locking mechanism 1 includes the boss outwardly protruded from the edge of centre wheel 25, which serves as locking piece.First blocking
One end of part 12 is fixedly mounted in rack, and the other end has the first slotted hole 121.One end of second block piece 13 is fixedly mounted
In rack, the other end has the second slotted hole 131.The both ends of third connecting rod 29 are respectively provided with the first opening and the second opening,
First connector (such as pin) passes through the first slotted hole 121 and first opening to connect the first block piece 12 and third connecting rod 29
Come.One end of push rod 30 is mounted in rack, and the other end has third slotted hole 301.Second connector (such as pin) passes through the
Two slotted holes, the second opening and third slotted hole connect the second block piece, third connecting rod and push rod.It is double in such as Fig. 5
Transfer switch is in the first power position, and the first spring 14 makes it lean against along the first block piece of clockwise bias 12
On boss.Second spring 15 makes it lean against on centre wheel along the second block piece of biased counter-clockwise 13.
In the following, describing the course of work of the locking mechanism of 3rd embodiment according to the present utility model referring to Fig. 8-12.
As shown in figure 8, display dual-power transfer switch is in the first power position, at this point, the first block piece 12 exists
It is leaned against on boss under the action of first spring.When the second electromagnet is activated, when centre wheel being made to rotate clockwise, boss is de-
From with the contact of the first block piece, to be rotated into the space between the first block piece and the second block piece, at this time first resistance
Block piece is biased under the action of the first spring and is contacted with centre wheel, and can be abutted with the lower part of boss, while the second resistance
Block piece is also abutted with the lower part of boss in opposite side, to which boss to be maintained between the first block piece and the second block piece, such as
Shown in Fig. 9.Preferably, in the present embodiment, the spacing between the first block piece and the second block piece is more than the size of boss, this
Boss is vibrated between the first block piece and the second block piece, it is final to stablize in the first block piece and the second block piece
Between.Otherwise, if the spacing between the first block piece and the second block piece is exactly equal to the size of boss, it is likely that boss
The space between the first block piece and the second block piece can be vibrated, cause lockout failure.
As shown in Figure 10, when needing to be switched to second source on-position from double points of positions, third electromagnet quilt first
Excitation, to push down on push rod, third connecting rod drives the first connector to be moved in the first slotted hole to make the first blocking
Part overcomes the effect of the first spring along rotation counterclockwise, third connecting rod drive the second connector in the second slotted hole it is mobile to
So that the effect that the second block piece overcomes second spring is rotated clockwise, this make the first block piece and the second block piece be detached from
The lower part of the boss against as centre wheel is further rotated along clockwise, the boss rotates out of the first block piece
And the second space between block piece, so that dual-power transfer switch is reached second source on-position, as shown in figure 11.Then,
As shown in figure 12, third electromagnet fails, and the first block piece is by the first spring bias to latched position, the second block piece quilt
Second spring is biased into latched position.
The locking mechanism of the dual-power transfer switch of the utility model is described above.It therefore deduces that, this practicality is new
Dual-power transfer switch can be reliably locked in double point positions by the locking mechanism of type, realize the first power position, double
Divide the reliable switching between position and second source on-position.
Moreover, each technical characteristic of above-mentioned disclosure is not limited to disclosed and other feature combination, art technology
Personnel can also carry out other combinations between each technical characteristic according to purpose of utility model, be with the purpose for realizing the utility model
It is accurate.
