Specific embodiment
As shown in Figs. 1-5, to include that arc-chutes 1 and two are external control brake gears 4 to the utility model, there are two arc-chutes 1 are set
Symmetrical end of incoming cables 2 and leading-out terminal 3 are equipped with close/open machine 5 inside arc-chutes 1, and close/open machine 5 includes dynamic contact block 51 and two
A symmetrically arranged stationary contact block 53 is equipped with power-off block 54, in its natural state, two stationary contact blocks 53 between two stationary contact blocks 53
It in separation, is not electrically connected, moves the top that contact block 51 is set to stationary contact block 53, move corresponding between contact block 51 and two stationary contact blocks 53
If being connected there are two symmetrical division block 52 and by division block 52, division block 52, dynamic contact block 51 and stationary contact block 53
It is equipped with inclined-plane, position is corresponding and parallel to each other between inclined-plane, and two parallel sides of division block 52 are equipped with connection
Column 55 is equipped with the first spring 57 between the connecting column 55 of two division blocks 52, passes through the first bullet between two division blocks 52
Spring 57 connects, and cooperates the dynamic contact block 51 of second spring 56, under the action of second spring 56, pushes naturally, two division blocks
52 because be connected to the first spring 57, naturally relatively sliding under the action of 41 pulling force of pull rod, so that 53 He of stationary contact block
Dynamic contact block 51 separates, and is in gate-dividing state, the first spring 57 is to the state being always stretched between two dynamic contact blocks 51, institute
The case where not reel power, there is the phenomenon that contraction, the spring ratio of second spring 56 is far smaller than the elastic force system of the first spring 57
Number, so the downward pressure of the dynamic contact block 51 connecting with second spring 56 does not influence the contraction of the first spring 57, stationary contact block 53 divides
It is not electrically connected between end of incoming cables 2 and leading-out terminal 3；Outside control brake gear 4 be equipped with gag lever post 42 and with 42 position of gag lever post
The pressing limited block 43 matched is equipped with pull rod 41 between gag lever post 42 and division block 52 and is connected by pull rod 41, pull rod 41 with
Gag lever post 42 is vertical, and pull rod 41 is arranged in inside end of incoming cables 2 and leading-out terminal 3, pull rod 41 respectively at end of incoming cables 2 and leading-out terminal 3 it
Between be equipped with sealing ring, because of this kind of devices of general arc-chutes 1, require the stable environment of sealing, keep in arc-chutes 1
Gas it is pure.
In a preferred embodiment, moving contact block 51 is isosceles tri-prismoid, and stationary contact block 53 is pentagonal prism body, and division block 52 is
Right-angled trapezium quadrangular moves and is equipped with sliding slot between the inclined-plane of contact block 51 and the inclined-plane of division block 52 and is connected by sliding slot, moves
It is equipped with sliding slot between the bottom surface of contact block 51 and the top surface of stationary contact block 53 and is connected by sliding slot, sliding pearl is equipped in sliding slot, reduction rubs
Resistance is wiped, can guarantee the speed of divide-shut brake to a certain degree, and reduces the quality and spring ratio requirement of the first spring 57, is moved
It is equipped with second spring 56 between the top surface and arc-chutes 1 of contact block 51 and is connected by second spring 56, second spring 56 is located always
In compressed state, under natural conditions, a downward stretching force will be generated, so that dynamic contact block 51 also pushes, the first spring
57 spring ratio is far longer than the spring ratio of second spring 56, dynamic contact block 51 is pushed naturally, and do not influence
The contraction of first spring 57, sealing ring are rubber ring, and electric conductivity is good, and power-off block 54, division block 52 are collets.
The principles of the present invention and the course of work are as follows:
As shown in figure 3, the pull rod 41 connecting with gag lever post 42 is in non-limiting state, and presses in the state of separating brake power-off
Pressure limited block 43 does not connect, two division blocks 52 not 41 pulling force effect of tension member, and two division blocks 52 are the
It under the action of one spring, 57 convergent force, is abutted together, so that dynamic contact block 51 and the separation of stationary contact block 53 achieve the effect that power-off；
As shown in figure 4, the pull rod 41 connecting with gag lever post 42 is pressed limited block 43 and limits position in the state of energization of closing a floodgate
It sets, so that two 52 tension member of division block, 41 pulling force are separated from each other, due to the presence on inclined-plane parallel to each other, dynamic contact block 51 exists
Under the stretching force of second spring 56, pushes to connect with stationary contact block 53 to 53 direction of stationary contact block and reach power effect；
When divide-shut brake is converted, pressing limited block 43 and pull rod 41 need to be only controlled, under "on" position, limited block 43 will be pressed
It is pressed into bottom, the position of pull rod 41 will cannot be limited by this moment pressing limited block 43, and pull rod 41 is natural under the effect of the first spring 57
Retraction forms separating brake；Under gate-dividing state, pressing limited block 43 is pressed, to pull rod 41 plus an outside pulling force, when pull rod 41
42 position of gag lever post be more than pressing 43 position of limited block when, unclamp pressing limited block 43, unclamp again pull rod 41, at this time pressing limit
Position block 43 will block gag lever post 42, so that two division blocks 52 separate, move contact block 51 and the contact of stationary contact block 53 is formed and closed a floodgate.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
