Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of breaker spring mechanism mechanical interlocking, including
Mechanism right plate 1, conjunction divide interlock plate 5, energy storage to keep buckle 10, pin 1, pin 2 13, pin 3 14, pin 4 15 and main connecting lever 17,
The outer surface of mechanism right plate 1 is equipped with interlock plate 2, one end and the energy storage of upper interlock plate 2 keep the pin on buckle 10 into
Row pivot pin connects, and the other end of upper interlock plate 2 is set on the pin 1 being threadedly coupled on the right side of mechanism 1, lower interlock plate 7
It is set on the pin 3 14 and pin 4 15 being threadedly coupled on the right side of mechanism 1, and the water of upper interlock plate 2 and lower 7 upper end of interlock plate
Flat slot hole is connected by pin 2 13, opens that there are two vertical slot hole, the connections of upper interlock plate 2 and lower interlock plate 7 on lower interlock plate 7
Part pin 1, pin 3 14, pin 4 15 constraint under can move up and down, 3 14 mounting hole of pin on lower interlock plate 7
Downside is connected with interlocking resetting spring 3, and the outer surface of the other end of interlocking resetting spring 3 and mechanism right plate 1 is fixed and connected
It connects, energy storage keeps the crook of buckle 10 is interspersed to be provided with buckle axis 19, and one end of buckle axis 19 is fixed with mechanism right plate 1
Connection, energy storage keep one end of buckle 10 to be in contact with the roller on the cam 18 of 1 outer surface of mechanism right plate by axis pin,
Conjunction divides interlock plate 5 to be fixed on 1 outer surface of mechanism right plate by pivot pin 6, closes and divides one end of interlock plate 5 and setting right in mechanism
Connecting lever 16 on side plate 1 contacts, and connecting lever 16 is arranged by shaft in 1 lateral surface of mechanism right plate with main connecting lever 17, closes and divides
One end of interlock plate 5 connects spring 4 by interlocking and is connected with the bottom of lower interlock plate 7, and closes and interlock plate 5 is divided to refer to by closing to divide
Show that steel wire 8 is connected to the one end closed and divide direction board 9, conjunction divides direction board 9 to divide the progress axis pin of direction board pin 11 to connect with conjunction, and conjunction point refers to
Show board pin 11 and the interspersed setting of 1 medial surface of mechanism right plate.
Operation principle：When spring operating mechanism energy storage in place and breaker is in gate-dividing state constantly, on cam 18
Roller keeps buckle 10 to be in contact with energy storage, is ready for closing operation.Lower interlock plate 7 and a whole set of interlocking component are in interlocking resetting
Direction board 9 is divided to be in separating brake indicating bit by closing a point pulling for instruction steel wire 8 in position shown in figure two, conjunction under the action of spring 3
It sets, conjunction divides the other end of interlock plate 5 to lean against on the outer profile of connecting lever 16.Upper interlock plate 2 can move horizontally under this state, therefore
When pushing energy storage to keep buckle 10 by switching electromagnet or hand push button, energy storage keep buckle 10 can around buckle axis 19 into
Row is rotated clockwise threads off with cam 18, and cam 18 rotates clockwise the main connecting lever 17 of driving and connecting lever under the action of switching-in spring
16 rotate counterclockwise breaker are made to close a floodgate.Interlock in the unlocked state under the state, i.e., breaker can carry out combined floodgate behaviour
Make.
As shown in figure 3, cam 18 rotates clockwise when main connecting lever 17 and connecting lever 16 being driven to rotate counterclockwise to closing position,
Connecting lever 16 is depressed the one end for dividing interlock plate 5 to contact is closed, and the other end is upward by lower interlock plate 7 by the interlocking connection spring 4 of connection
Pull-up, 2 linkage section of interlock plate is lifted up in drive, and pin 1 is by the perpendicular of the anisotropic slot hole in 2 left end of upper interlock plate at this time
Straight section, to make upper interlock plate 2 can not carry out it is front and back move horizontally, therefore energy storage keeps buckle 10 that can not rotate, and close a floodgate electricity
Magnet or closing by hand cannot close a floodgate.Interlocking elements are in the lock state, close and divide direction board 9 by closing a point instruction steel wire
8 pulling is in combined floodgate indicating positions, it is same when circuit breaker external interlocking elements from the plane of 7 bottom of lower interlock plate by lower interlocking
Plate 7 jacks up upwards, then same interlocking elements are in the lock state.
When pushing energy storage that buckle 10 is kept to be closed a floodgate, pin 1 is by the anisotropic slot hole in 2 left end of upper interlock plate
Horizontal segment, above interlock plate 2 will be unable to move up and down at this time.But since lower interlock plate 7 and conjunction divide interlock plate 5 to be connected by interlocking
Spring 4 is attached, and stretcher strain is lifted up by interlocking connection spring 4 again after the reset of upper interlock plate 2 reaches lock-out state.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
