Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
In order to solve the above-mentioned technical problem, the utility model embodiment provides a kind of aligning gear, and the aligning gear can
With as shown in Fig. 2 including：Base 90, magnet 10 and yoke 20；Wherein, magnet 10 is rotatably arranged on base 90, magnet 10
On be connected with the catch 40 rotated with magnet 10；Coil 30 is wound with yoke 20, coil 30 is powered and formed in yoke 20
Two magnetic poles, magnet 10 is arranged between two magnetic poles of yoke 20；Magnet 10 can turn between the first position and the second position
It is dynamic, and magnet 10 be in the first position or second place state under, two magnetic poles of magnet 10 respectively with yoke 20 two
Magnetic pole is corresponding.
When coil 30 is not powered on：
Yoke 20 attracts magnet 10 to stop to first position, and magnet 10 drives catch 40 to stop to off-position；Or,
Yoke 20 attracts magnet 10 to stop to the second place, and magnet 10 drives catch 40 to stop to operating position；
When coil 30 is powered：
Yoke 20 promotes magnet 10 to be moved to the second place from first position, and magnet 10 drives catch 40 to working position
Put；Or, yoke 20 promotes magnet 10 to be moved to first position from the second place, and magnet 10 drives catch 40 to inoperative
Position.
Specifically, in the case where catch 40 is stopped to off-position, when coil 30 is logical positive electric, yoke 20 is promoted
Magnet 10 is moved to the second place from first position, and magnet 10 drives catch 40 to operating position；
In the case where catch 40 is stopped to operating position, coil 30 lead to negative sense it is electric when, yoke 20 promotes magnet 10 from the
Two positions are moved to first position, and magnet 10 drives catch 40 to off-position.
In the present embodiment, yoke is fixed, and magnet can be rotated, when the coil is not energized, and magnet attracts each other with yoke,
Yoke attracts magnet to stop to first position, that is to say, that magnet is in the first position under state, two magnetic poles and magnetic of magnet
Two magnetic poles of yoke are corresponding：The N poles of magnet and the S of yoke are extremely corresponding, and the S poles of magnet and the N of yoke are extremely corresponding.Magnet
It is connected with catch, magnet is stopped to first position, and catch is just stopped to off-position.For example, magnet is stopped to first
During position, N, S extreme direction can be as shown in Figure 3.
Now, the logical positive electricity of coil 30, yoke 20 produces magnetic, as shown in figure 4, yoke 20 is produced after magnetic, with magnet
10 is mutually exclusive, due to repulsive interaction, and yoke 20 promotes the second place that the first position from Fig. 4 of magnet 10 is turned in Fig. 5.
Magnet is attracted each other at 10 second place with yoke 20, and magnet is just stopped to the second place, that is to say, that magnet is in
Under two location status, two magnetic poles of magnet are corresponding with two magnetic poles of yoke：The N poles of magnet and the S of yoke are extremely corresponding,
The S poles of magnet and the N of yoke are extremely corresponding.Magnet is connected with catch, and magnet is stopped to the second place, and catch is just stopped to work
Make position.
As can be seen here, during device looses power, due to the attraction of yoke, magnet can rest on the second place, and catch can be rested on
Operating position.Therefore, when device looses power, catch can continue to that detector is carried out to block protection.
Now, if coil leads to negative sense electricity, yoke produces the magnetic opposite with Fig. 3, as shown in fig. 6, yoke is produced
Mutually exclusive with magnet after magnetic, due to repulsive interaction, yoke promotes that magnet second place from Fig. 6 is turned in Fig. 3
One position.Magnet is attracted each other at first position with yoke, and magnet is just stopped to first position.Magnet is connected with catch, magnetic
Body is stopped to first position, and catch is just stopped to off-position.
As a kind of embodiment, as shown in figure 3, magnet 10 can be annular magnet, yoke 20 is U-shaped yoke, U-shaped magnetic
The curved parcel annular magnet of two pole end pieces of yoke.Compared to existing U-shaped yoke, the U-shaped yoke in present embodiment
Two magnetic poles closer to the magnetic pole of annular magnet, so, bigger active force can be produced between magnetic pole, yoke can be promoted
The angle that magnetic pole is rotated is bigger.Therefore, when the operating position of catch differs larger with off-position angle, using this implementation
Mode can still realize that catch blocks protection to detector.
