Background technology
According to the intelligentized demand of China's supply network, State Grid Corporation of China requires supply network intelligent.Therefore it needs
The end effector of supply network --- miniature circuit breaker executes upper end signal and has tripping, closing function.Therefore small-sized disconnected
Device current development trend in road is to have outside traditional manual divide-shut brake and the automatic tripping function of over-current and -load, it is also necessary to be had
There are automatic divide-shut brake and reclosing function, to realize remote control；Intelligent electric meter is especially combined, realizes that arrearage automatic trip is disconnected
Electricity fills the function of expense automatic closing power transmission.In the prior art, breaker overlap brake mechanism in tripping mechanism structure mostly
More complicated, constituent parts quantity is more, and stability is general.
Invention content
In this regard, the present invention is intended to provide a kind of structure relative simplicity is reasonable, the good dropout linkage mechanism of stability.
Realizing the technical solution of the object of the invention is：
A kind of dropout linkage mechanism includes linking by the driving wheel of Vidacare corp driving rotation and with the driving wheel
Dropout frizzen, the dropout frizzen may be rotatably mounted at by installation axle on Shell of circuit breaker, the dropout frizzen
One end be the connecting pin being connected with driving wheel, the other end is the triggering end for triggering the dropout of circuit breaker tripping axis；
It is formed on the driven wheel side end face around its centrally disposed guiding groove, the connecting pin is fixed with connecting pole
Body, the connection cylinder stretch into the guiding groove, opposite in guiding groove by connecting cylinder when the driving wheel is rotated
Movement is to drive the dropout frizzen to move up and down.
In above-mentioned technical proposal, the guiding groove is closed ring structure comprising opposite and concentric orthodrome slot
With small arc-shaped slot, and the transition link slot of be connected smoothly the orthodrome slot and small arc-shaped slot, the orthodrome slot
Radius is more than the radius of the small arc-shaped slot.
In above-mentioned technical proposal, central angle alpha >=π of the orthodrome slot.
In above-mentioned technical proposal, the driving wheel is circular gear.
The present invention has the effect of positive：The constituent parts negligible amounts of dropout linkage mechanism in the present invention, structure
Advantages of simple is inserted into the connection and linkage of realization driving wheel and dropout frizzen in guiding groove by connecting cylinder, it may have very
Good stability when the dropout linkage mechanism is installed and used, to control circuit breaker tripping, then controls Vidacare corp rotation
And then driving wheel rotation is driven, further make open circuit by driving release lever action that triggering end is made to compress circuit breaker tripping axis downwards
Device is threaded off, and when needing breaker closing, control Vidacare corp continues rotation to by driving release lever action to make to touch
Originator leaves circuit breaker tripping axis, thus can normal control breaker closing.

Specific implementation mode
The concrete structure in the present invention is done with explanation with reference to the accompanying drawings of the specification：
A kind of dropout linkage mechanism, as shown in Figure 1 to Figure 3 comprising driven rotation to be driven by Vidacare corp 01
Wheel 1 and the dropout frizzen 2 to link with the driving wheel 1, the dropout frizzen 2 may be rotatably mounted at disconnected by installation axle 3
On the device shell of road, one end of the dropout frizzen 2 is the connecting pin 21 being connected with driving wheel 1, and the other end is for touching
Send out the triggering end 22 that circuit breaker tripping axis 4 is threaded off；It is formed on 1 side of the driving wheel around its centrally disposed guiding groove
11, the connecting pin 21 is fixed with connection cylinder 5, and the connection cylinder 5 stretches into the guiding groove 11, in the driving wheel 1
By connecting cylinder 5 in the interior relative movement of guiding groove 11 to drive the dropout frizzen 2 to move up and down when rotation.This implementation
The constituent parts negligible amounts of dropout linkage mechanism in example, it is simple and reasonable, it is inserted into guiding groove 11 by connecting cylinder 5
The interior connection and linkage for realizing driving wheel 1 and dropout frizzen 2, it may have good stability, dropout linkage mechanism installation
In use, to control circuit breaker tripping, then controls Vidacare corp 01 and rotate and then driving wheel 1 is driven to rotate, further
Make circuit breaker tripping by driving release lever action that triggering end 22 is made to compress circuit breaker tripping axis 4 downwards, closed when needing breaker
When lock, control Vidacare corp 01 continues rotation to by driving release lever action that triggering end 22 is made to leave circuit breaker tripping
Axis 4, thus can normal control breaker closing.
Shown in Fig. 4, the guiding groove 11 in the present embodiment is closed ring structure comprising opposite and concentric
Orthodrome slot 12 and small arc-shaped slot 13, and the orthodrome slot 12 that is connected smoothly connects with the transition of small arc-shaped slot 13
Slot 14, the radius of the orthodrome slot 12 is more than the radius of the small arc-shaped slot 13, during the driving wheel 1 rotates,
When connecting cylinder 5 and being moved in orthodrome slot 12, dropout frizzen 2 is remained stationary as and is separated with circuit breaker tripping axis 4, when even
Driven when connecing cylinder 5 in the transition link slot 14 and being moved into small arc-shaped slot 13 2 action of dropout frizzen make triggering end 22 by
Gradually make circuit breaker tripping close to circuit breaker tripping axis 4, triggering end 22 then compresses when connecting cylinder 5 and resting in small arc-shaped slot 13
On circuit breaker tripping axis 4 and circuit breaker tripping axis 4 is in trip positions, and breaker can not close a floodgate at this time, work as connecting pole
Body 5 drives 2 action of dropout frizzen to keep triggering end 22 gradually remote in transition link slot 14 and when being moved into orthodrome slot 12
From breaker trip shaft 4, to not interfere the combined floodgate of breaker.
Further, in the present embodiment, central angle alpha >=π of the orthodrome slot 12, the driving wheel 1 is circular gear.
Shown in Fig. 5, the dropout linkage mechanism in the present embodiment can be used in reclosure mechanism of disconnector, be owed in user
It is time-consuming, circuit breaker tripping is controlled by the dropout linkage mechanism, to cut off power supply.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And these
The obvious changes or variations that the connotation for belonging to of the invention is extended out still fall within protection scope of the present invention.
