Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to shown in Fig. 1 to Fig. 3, the invention discloses a kind of breaker mechanism and the interlock of three position mechanism, connect
Locking device include connecting lever 10, supporting plate 20, the first guide plate 30, the second guide plate 40, connecting rod 50, the 3rd guide plate 60 and
Locking bar 70；One end of connecting lever 10 is arranged on breaker splined shaft 80, and the other end of connecting lever 10 connects one end of the first connecting plate 90,
The other end of first connecting plate 90 connects one end of the second connecting plate 100；During work, breaker splined shaft 80 is used to drive 10 turns of connecting lever
Dynamic, connecting lever 10 drives the first connecting plate 90 to rotate, and the first connecting plate 90 drives the second connecting plate 100 to rotate；Supporting plate 20 is fixed on three works
In the mechanism of position, supporting plate 20 plays a part of the whole interlock of support；First guide plate 30 is arranged on supporting plate 20, and first
Guide plate 30 is L-type, and the end face of the first guide plate 30, which is provided with first through hole 31, the other end of the first guide plate 30, to be set
There is semicircular notch 120；Second guide plate 40 is arranged on end face of first guide plate 30 provided with semicircular notch 120, the
Two guide plates 40 be arranged in parallel with end face of first guide plate 30 provided with first through hole 31, and the second guide plate 40 is provided with second
Through hole 41, the horizontal center line axis of the second through hole 41 and the horizontal center line axis of first through hole 43 are point-blank；The company
One end of extension bar 50 is arranged in the semicircular notch 120 of the first guide plate 30, and is connected with the other end of the second connecting plate 100,
Connecting rod 50 is driven by the second connecting plate 100, and it can be moved in semicircular notch 120；3rd guide plate 60 is L-type, the 3rd
One end of guide plate 60 is connected with the other end of connecting rod 50, and the other end of the 3rd guide plate 60 is provided with third through-hole 61, the
The horizontal center line axis of three through holes 61 and the horizontal center line axis and the horizontal center line axis of first through hole 31 of the second through hole 41
Point-blank, the 3rd guide plate 60 drives it to move left and right by connecting rod 50；One end of locking bar 70 passes through first through hole
31st, the second through hole 41, third through-hole 61, are finally fixed on the 3rd guide plate 60, drive of the locking bar 70 in the 3rd guide plate 60
Under can be moved left and right in first through hole 31, the second through hole 41, the other end of locking bar 70 blocks three position mechanism when stretching out
Cover plate 140 is operated, causes operation cover plate 140 not open；First guide plate 30 and the second guide plate 40 are to strengthen supporting plate
Fixation, while also undertaking the guide effect of locking bar 70, it is ensured that locking bar 70 and first is won in succession and 90, second won in succession between 100
Run unimpeded smooth.
Interlock of the present invention also includes a reseting pressuring spring 140, and reseting pressuring spring 140 is set on locking bar 70, and positioned at the
Between one through hole 31 and the second through hole 41, the fit clearance between reseting pressuring spring 140 can make locking bar 70 and win in succession does not influence chain
The accuracy of operation, it is ensured that locking bar can be operated in place, reaches at a relatively high reliability.
The present invention operationally, is rotated during by the divide-shut brake of breaker splined shaft 80, is driven connecting lever 10 to swing up and down, is turned
Arm 10 promotes first to win in succession and 90 and second won in succession 100 linkages, and second wins 100 in succession by connecting rod 50, the 3rd guide plate 60 and lock
Bar 70 is linked, and drives the stretching motion of locking bar 70, the operation cover plate 130 of three position mechanism is blocked when locking bar 70 stretches out, behaviour is caused
Making cover plate 130 can not open, and operation handle can not insert three position mechanism operation, make not operating manually, reach purpose of design.
