In this regard, the utility model is intended to provide, a kind of structure relative simplicity is reasonable, the good tripping linkage mechanism of stability.
Realizing the technical solution of the utility model aim is:
A kind of tripping linkage mechanism links including the driving wheel by Vidacare corp driving rotation and with the driving wheel
Tripping frizzen, the tripping frizzen may be rotatably mounted in circuit breaker housing by installation axle, the tripping frizzen
One end be the connecting pin being connected with driving wheel, the other end is the triggering end for triggering the tripping of circuit breaker tripping axis；
The guiding groove around the setting of its center is formed on the driven wheel side end face, the connecting pin is fixed with connecting column
Body, the connection cylinder protrude into the guiding groove, opposite in guiding groove by connection cylinder in driving wheel rotation
Movement is to drive the tripping 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 greater 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 utility model has the effect of positive: in the utility model tripping linkage mechanism constituent parts quantity compared with
It is few, it is simple and reasonable, the connection and linkage of realizing driving wheel and thread off frizzen is inserted into guiding groove by connection cylinder,
With good stability, when which installs and uses, to control circuit breaker tripping, then electric drive dress is controlled
It sets and rotates and then drive driving wheel rotation, further by driving release lever movement that triggering end is made to compress circuit breaker tripping axis downwards
Make circuit breaker tripping, when needing breaker closing, control Vidacare corp continues rotation to by driving release lever dynamic
Work makes triggering end leave circuit breaker tripping axis, thus can normal control breaker closing.

Specific embodiment
The specific structure in the utility model is done to illustrate with reference to the accompanying drawings of the specification:
A kind of tripping linkage mechanism, as shown in Figure 1 to Figure 3 comprising by the driving of the driving rotation of Vidacare corp 01
Wheel 1 and the tripping frizzen 2 to link with the driving wheel 1, the tripping frizzen 2 may be rotatably mounted at disconnected by installation axle 3
On the device shell of road, one end of the tripping 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；The guiding groove around the setting of its center is formed on 1 side of driving wheel
11, the connecting pin 21 is fixed with connection cylinder 5, and the connection cylinder 5 protrudes into the guiding groove 11, in the driving wheel 1
It by connecting cylinder 5 relatively moves that the tripping frizzen 2 is driven to move up and down in guiding groove 11 when rotation.This implementation
The constituent parts negligible amounts of tripping linkage mechanism in example, it is simple and reasonable, guiding groove 11 is inserted by connection cylinder 5
The interior connection and linkage for realizing driving wheel 1 and frizzen 2 of threading off, it may have good stability, tripping linkage mechanism installation
In use, then controlling Vidacare corp 01 to control circuit breaker tripping and rotating and then driving wheel 1 is driven to rotate, further
By driving release lever movement to make triggering end 22 compress circuit breaker tripping axis 4 downwards to make circuit breaker tripping, when needing breaker to close
When lock, control Vidacare corp 01 continues rotation to by driving release lever movement that triggering end 22 is made to leave circuit breaker tripping
Axis 4, thus can normal control breaker closing.
Referring to 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 are greater than the radius of the small arc-shaped slot 13, during the driving wheel 1 rotation,
When connecting cylinder 5 and moving in orthodrome slot 12, tripping frizzen 2 is remained stationary and is separated with circuit breaker tripping axis 4, when even
Cylinder 5 is connect in transition link slot 14 and when moving into small arc-shaped slot 13 and drives the tripping movement of frizzen 2 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 column
Body 5 drives the tripping movement of frizzen 2 to keep triggering end 22 gradually remote in transition link slot 14 and when moving 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.
Referring to shown in Fig. 5, the tripping linkage mechanism in the present embodiment can be used in reclosure mechanism of disconnector, owe in user
It is time-consuming, circuit breaker tripping is controlled by the tripping linkage mechanism, to cut off power supply.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still fall within it is practical
Novel protection scope.
