Description
Technical field
The utility model belongs to technical field of electric appliances, is transported more particularly, to division board in a kind of open frame circuit breaker drawer chassis
Motivation 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, because open frame circuit breaker is to be installed in drawer and can be moved in drawer, with side
Just the advantage with maintenance is detected, thus is widely used.
Open frame circuit breaker is made up of breaker body and drawer type socket two large divisions, and it in use, can
To disconnect electric loop by breaker main contact, the breaking point in a loop is formed, 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 can not be switched on or switched off, electrically returning for load
Road, accordingly, it would be desirable to which an interlock ensures 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.
It is to shake when manipulating screw mandrel but the drawer holder structure of the open frame circuit breaker used in prior art has shortcoming
Screw mandrel and breaker is left after experimental site, further shake into screw mandrel, safety barrier plate should be with the movement of breaker on
Rise, the drawer chassis in existing structure is with the movement of breaker, and safety barrier plate translational speed is slow, and safety insulation door is upper
Situation that is stuck and can not rising occurs during rising, causes the damage of division board, influence breaker body side bus is with taking out
The break-make and contact effect of drawer seat bridge-shaped contact are so that trigger accident.
Utility model content
The purpose of this utility model is just to provide for isolating plate movement mechanism in a kind of open frame circuit breaker drawer chassis, with
Solve the problem of safety insulation door kinetic stability in available frame circuit breaker drawer base is not enough, action is not rapid enough.
The purpose of this utility model can be achieved through the following technical solutions：
Isolate plate movement mechanism in a kind of open frame circuit breaker drawer chassis, described drawer chassis includes the drawer of the left and right sides
Seat side plate, case, are provided with division board in case；
Described isolation plate movement mechanism include upper connecting rod, lower link, sliding axle, guide rail and motion side plate, it is described every
From plate perpendicular to drawer chassis side plate, described lower link is rotatably connected on drawer chassis side plate, described upper connecting rod upper end with every
From plate connection, lower end is hinged with lower link, and described sliding axle is located in upper connecting rod, and described guide rail is fixed on drawer chassis side plate
On, described sliding axle is contacted with guide rail upper surface, and described guide rail limits track as the motion of sliding axle, it is ensured that upper connecting rod
During motion, its upper end vertex is moved up and down, and described motion side plate is parallel to drawer chassis side plate, and described motion side plate level is slided
Lower link is promoted to rotate during dynamic, the rotation of lower link drives upper connecting rod motion, and the motion of upper connecting rod is driven above and below division board
It is mobile.
Face is transitioned between the lower link and motion side plate by linear contact lay in motion process to contact.
It is cut into hypotenuse in described motion side plate upper end forward position.
The lower surface of described lower link is made up of one section of arcwall face with one section of horizontal plane, is moved forward and backward in motion side plate
Cheng Zhong, the hypotenuse for moving side plate upper end forward position is first contacted with the arcwall face of lower link lower end, is promoted lower link to rotate, is moved afterwards
The upper surface of side plate and the horizontal plane sliding contact of lower link lower end, now, division board stop moving up and staying open shape
State.The horizontal plane of lower link lower end constitutes position limiting structure, is protected after lower link passive movement side plate promotes and rotates to certain angle
Hold constant, that is, ensure with the movement of motion side plate after division board is opened completely, division board stops moving up and keeps beating
Open state.
Lower link is promoted by motion side plate, and horizontal plane and the motion side plate upper surface of lower link are rotated to by initial position
Overlap, therefore, the lower link anglec of rotation is by horizontal plane control.If without horizontal plane, all replaced by arcwall face, then division board
Rise excessively, and set after horizontal plane, due to defining the movement angle of lower link, at this point it is possible to which so that division board rises to
Correct 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 division 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, the fluency of increase motion motion.
The middle part of described lower link is rotatably installed on drawer chassis side plate by rotating screw, described lower link it is upper
The lower end with upper connecting rod is held to be hinged by rivet.
The upper end of described upper connecting rod is provided with the toroidal with opening, and opening is positioned at the top of annulus, described
Division board both sides be provided with division board chute, and the division board chute be located at upper connecting rod upper end annulus in.The upper connecting rod
Connection with division board is using the larger circle in aperture, and this structure can allow one that mechanism is produced in manufacture processing and installation
Determine error, there is certain tolerance.
Described guide rail is screwed on drawer chassis side plate.
Described guide rail upper surface is is made up of the arcwall face of two sections of opposite directions, similar serpentine.
The movement locus of sliding axle is approximately the same when described guide rail upper surface shape is moved up and down with upper connecting rod summit.Lead
Rail shape is that the move contrail fitting of sliding axle in upper connecting rod when being moved up and down according to division board is formed.
The motion principle of the utility model motion is as follows：Motion side plate is driving link, and motion side plate is in motion side plate
Moved on chute, move to certain position and promote lower link, the rotation of lower link drives upper connecting rod motion, the sliding axle of upper connecting rod
Being limited by guide rail makes sliding axle be moved along guide rail, so as to realize that the summit of upper connecting rod is moved up and down, that is, realizes division board
Move up and down.
Compared with prior art, the utility model has the advantages that：
Upper connecting rod is with lower link using being hinged in the utility model, and motion process is unobstructed, and lower link is pushed away by motion side plate
Dynamic formula, upper connecting rod can be rotated freely, be not in stuck situation, and stability is strong, and compared to other mechanisms, door opening action is more
To be rapid.In addition, the shape in the utility model for lower link has carried out new design, by the arc for having set position-limiting action
Shape portion ensures lower link range of movement, i.e., by lower link structure design, limiting the movement angle of lower link, it is ensured that
Mechanism will not pass through dead point, it is ensured that reliable in action performance.In addition, tracking out upper connecting rod by the moving track calculation of division board
The movement locus of upper sliding axle, the size shape of guide rail, serpentine guide rail are gone out according to the move contrail fitting of sliding axle in upper connecting rod
Moving up and down for upper connecting rod upper end vertex is ensure that, that is, meets the requirement that division board is moved up and down.
