Description
Technical field
The invention belongs to technical field of electric appliances, more particularly, to isolation board fitness machine in a kind of open frame circuit breaker drawer chassis
Structure.
Background technology
Omnipotent breaker is also referred to as frame-type circuit breaker, can turn on, carry and disjunction normal circuit under the conditions of electric current,
Also can under defined improper circuit condition disjunction fault current.For the application of omnipotent breaker, it is divided into fixed
Breaker and open frame circuit breaker have side since open frame circuit breaker is installed in drawer and can be moved in drawer
Just the advantages of detection is with repair, thus be widely used.
Open frame circuit breaker is made of breaker body and drawer type socket two large divisions, in use, can
To disconnect electric loop by breaker main contact, the breaking point in a circuit is formed, it can also be by breaker body and drawer type
The insulating contact of the tie point composition of socket disconnects electric loop.But insulating contact, which cannot be switched on or switched off, has the electrical of load to return
Road, therefore, it is necessary to an interlocks to ensure insulating contact when being switched on or switched off electric loop, at the main contact of breaker
In off-state, to ensure that insulating contact is operated in the case of zero load.
But there is shortcoming in the drawer holder structure of the open frame circuit breaker used in prior art, shaken when manipulating lead screw
Lead screw and after so that breaker is left experimental site, further shake into lead screw, safety barrier plate should with the movement of breaker and on
It rises, the drawer chassis in existing structure is with the movement of breaker, and safety barrier plate movement speed is slow, and safety insulation door is upper
Will appear during rising it is stuck and the case where cannot rise, lead to the damage of isolation board, influence breaker body side bus and take out
The break-make and contact effect of drawer seat bridge-shaped contact are so that cause accident.
Invention content
The purpose of the present invention is just to provide for that plate movement mechanism is isolated in a kind of open frame circuit breaker drawer chassis, to solve
The problem that safety insulation door kinetic stability is insufficient in available frame circuit breaker drawer base, action is not rapid enough.
The purpose of the present invention can be achieved through the following technical solutions：
Plate movement mechanism is isolated in a kind of open frame circuit breaker drawer chassis, the drawer chassis includes the drawer of the left and right sides
Seat side plate, case, are provided with isolation board in case；
The isolation plate movement mechanism include upper connecting rod, lower link, sliding axle, guide rail and movement side plate, it is described every
From plate perpendicular to drawer chassis side plate, the lower link is rotatably connected on drawer chassis side plate, the upper connecting rod upper end with every
It is connected from plate, lower end is hinged with lower link, and the sliding axle is located in upper connecting rod, and the guide rail is fixed on drawer chassis side plate
On, the sliding axle is contacted with guide rail upper surface, and the guide rail limits track as the movement of sliding axle, ensures upper connecting rod
When movement, endvertex moves up and down thereon, and the movement side plate is parallel to drawer chassis side plate, and the movement side plate level is slided
Push lower link rotation, the rotation of lower link that upper connecting rod movement, the movement of upper connecting rod is driven to drive isolation board or more during dynamic
It is mobile.
The face of being transitioned into is contacted between the lower link and movement side plate by line during the motion to contact.
It is cut into bevel edge in the movement side plate upper end forward position.
The lower face of the lower link is made of one section of arcwall face and one section of horizontal plane, is moved forward and backward in movement side plate
Cheng Zhong, the bevel edge for moving side plate upper end forward position are first contacted with the arcwall face of lower link lower end, are pushed lower link rotation, are moved later
The upper surface of side plate and the horizontal plane sliding contact of lower link lower end, at this point, isolation board stopping moves up and stays open shape
State.The horizontal plane of lower link lower end constitutes position limiting structure, is protected after rotating to certain angle when lower link is pushed by movement side plate
It holds constant, that is, ensures that the movement with movement side plate after isolation board is opened completely, isolation board stopping are moved up and kept dozen
Open state.
Lower link is pushed by movement side plate, and horizontal plane and the movement side plate upper surface of lower link are rotated to by initial position
It overlaps, therefore, lower link rotation angle is controlled by horizontal plane.If without horizontal plane, all replaced by arcwall face, then isolation board
Rise excessively, and after horizontal plane is arranged, due to defining the movement angle of lower link, at this point it is possible to which so that isolation board rises to
Suitable position.If changing the length ratio of arcwall face and horizontal plane in lower link, that is, adjust the position-adjustable of horizontal plane
The movement angle of lower link, at this point it is possible to adjust the position of isolation board rising.If deleting the arcwall face of lower link, only retain
Horizontal plane can also, but arcwall face primarily serves the effect of transition, increases the fluency of motion movement.
The middle part of the lower link by rotate screw be rotatably installed on drawer chassis side plate, the lower link it is upper
End and the lower end of upper connecting rod are hinged by rivet.
The upper end of the upper connecting rod is equipped with the annulus shape with opening, and is open positioned at the top of annulus, described
The both sides of isolation board be equipped with isolation board sliding slot, and the isolation board sliding slot is located in the annulus of upper connecting rod upper end.The upper connecting rod
Using the larger circle in aperture, this structure can allow one that mechanism is generated in manufacture processing and installation for connection with isolation board
Determine error, there is certain tolerance.
The guide rail is screwed on drawer chassis side plate.
The guide rail upper surface is to be made of the arcwall face of two sections of opposite directions, similar serpentine.
The movement locus of sliding axle is approximately the same when the guide rail upper surface shape is moved up and down with upper connecting rod vertex.It leads
Rail shape is that the move contrail fitting of sliding axle in upper connecting rod when being moved up and down according to isolation board forms.
The motion principle of motion of the present invention is as follows：Movement side plate is driving link, and movement side plate is in movement side plate sliding slot
Upper movement moves to certain position and pushes lower link, the rotation of lower link that upper connecting rod movement, the sliding axle of upper connecting rod is driven to be led
Rail limitation makes sliding axle be moved along guide rail, to realize that the vertex of upper connecting rod moves up and down, that is, realizes the upper of isolation board
Lower movement.
Compared with prior art, the present invention has the advantages that：
Using hinged, motion process is unobstructed for upper connecting rod and lower link in the present invention, lower link by movement side plate push type,
Upper connecting rod can be freely rotated, and be not in stuck situation, stability is strong, and compared to other mechanisms, door opening action is more fast
Speed.In addition, having carried out new design in the present invention for the shape of lower link, the curved portion by the way that position-limiting action is arranged is protected
Barrier lower link motion range ensure that mechanism will not that is, by lower link structure design, limiting the movement angle of lower link
Pass through dead point, it is ensured that reliable in action performance.In addition, tracking out sliding axle in upper connecting rod by the moving track calculation of isolation board
Movement locus, the size shape of guide rail is gone out according to the move contrail fitting of sliding axle in upper connecting rod, serpentine guide rail ensure that
Small end vertex moves up and down, that is, meets the requirement that isolation board moves up and down.
