Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in Fig. 1 combinations Fig. 2-11, a kind of interlocking device of switch cabinet, including the first bearing 1, the second bearing 2 and with connecing
The operating shaft 3 that ground connecting lever is connected, spacing driving member 4 is provided between described the first bearing 1 and the second bearing 2, it is described spacing
One end of driving member 4 is connected with interlocking mechanism 5, and the other end is connected with operating shaft 3, and described interlocking mechanism 5 includes being oriented to
Axle 51 and the locking part 52 for rear gate interlock, described spacing driving member 4 are provided with movable block 41, in described operating shaft 3
Provided with spacer pin 31, described movable block 41 is engaged the first shape of locked operating shaft 3 with spacer pin 31 when there is back door to open
State and back door unlock the second state that operating shaft 3 causes operating shaft 3 to circumferentially rotate when closing, described spacer pin 31 is being grounded
Released when switching separating brake to the first position of the axial limiting of movable block 41 and when earthed switch closes a floodgate and movable block 41 is axially limited
The second place of position.The beneficial effects of the utility model are movable block, spacer pin and interlocking mechanism, so that movable block energy
Operating shaft being carried out spacing so that operating shaft can not circumferentially rotate breaking-closing operating when earthed switch combined floodgate back door is opened, and
When back door is closed, movable block unlocks, the free breaking-closing operating of operating shaft energy, in operating shaft sub-switching operation to movable block axial direction
It is spacing, avoid movable block and the action of spacing driving member during grounding switch tripping from opening back door, can exclude to work during overhaul of line breaker
Potential safety hazard existing for personnel's maloperation, the utility model is simple in construction, easy for installation, interlocking is reliable, and Adapter Property is more preferable etc.
Advantage.
Specifically, when earthed switch closes a floodgate, spacer pin releases and movable block axial limiting, spacing driver plate is reset
Spring pulls, and promotes axis of guide motion, and locking part moves with the axis of guide, due to being connected with spring on one end of locking part, the bullet
Spring causes locking part to be oppositely oriented axle rotation, and interlocking portion unlocks after rotating to back door, and the through hole at back door makes right through interlocking portion
Back door is reliably opened, when spacing driver plate when pulled, movable block on spacing driver plate links with spacing driver plate,
Spacer pin is realized spacing along the spacer pin position that axially moves to of operating shaft, operating shaft can not rotate, and earthed switch can not
Separating brake, ensure the safety of maintainer.When (shrouding) is shut when back door, spacing driver plate is driven to move by the axis of guide, now
Locking part rotates with the axis of guide and interlocks back door, movable block give spacer pin step down so that operating shaft can rotate, realize separating brake,
Closing operation, after grounding switch tripping, spacer pin is realized to the spacing of movable block on the path that movable block moves, due to
Movable block motion is limited so that the axial movement of spacing driver plate is limited, and axis of guide akinesia, back door is interlocked can not
Open, so that back door can not be opened by reliable interlocking.

Motion block and spacer pin are in accommodating cavity, and the second bearing can play spacing effect to the motion of movable block so that movable block moves
Make steady reliable.
Described spacer pin 31 circumferentially rotates cooperation, described movable block 41 in accommodating cavity 21 and with the second bearing 2
Coordinate in accommodating cavity 21 and with the second bearing 2 along the axial slip of operating shaft 3.Specifically, set on described movable block 41
There is the deep-slotted chip breaker 411 being adapted with the outer surface of operating shaft 3.It is reliable that such structure causes operating shaft to rotate, and interlocking is reliable, is easy to
Realization is reciprocal interlocked.
Described locking part 52 is connected on the axis of guide 51 and with the axis of guide 51, and described locking part 52 is in activity
With avoiding first position that back door opens and in activity through through hole on back door and rear gate interlock when block 41 is in the second state
Block 41 causes the second place that locking part 52 can be from the through hole of back door by being easy to back door to open when being in first state.This practicality
It is new to be provided with interlocking mechanism, reliably locking part can be driven to act by the axis of guide, so that locking part can be reliable, fast
Speed, interlocking or unblock are easily realized with back door, simple with the through hole cooperation on back door, Adapter Property is more preferable, and this practicality
It is new also to have the advantages that simple in construction, easy for installation, interlocking is reliable, while staff grasps by mistake when being avoided that overhaul of line breaker
Make.
Described locking part 52 includes interlocking portion 521, articulated section 522 and connecting portion 523, and described locking part 52 is articulated with
On the axis of guide 51, described interlocking portion 521 and connecting portion 523 are set on the both sides of articulated section 522, the first described bearing 1
There is spring 11, described spring 11 is connected with connecting portion 523.In particular, described locking part 52 is at first position
Interlocking portion 521 and back door phase clamping, described locking part 52 locking part 52 at the second place, which is oppositely oriented axle 51 and rotated, to be caused
Interlocking portion 521 unlocks with back door.In particular, described locking part 52 is in inverted zigzag.The setting of spring to be oriented to
When axle acts, the fast and reliable unblock interlocking portion of energy, so that fast and easy is opened at back door, and interlocking is reliable in interlocking.
Locking part locking part is fixed by be hinged mode easy for installation, reliable in action, and locking part turns an angle, back door
It just can quickly open, facilitate staff to operate.
The described axis of guide 51 is provided with gap slot 511, and described locking part 52 is located in gap slot 511 and and the axis of guide
51 are hinged, and pilot sleeve 512 is arranged with outside the described axis of guide 51.Certain limit is played in the setting of gap slot to locking part
Position effect so that locking part stable action, avoid interfering in locking part action process, influence product Interlock Function.Pilot sleeve
Motion of the setting to the axis of guide play a part of limition orientation, while certain position-limiting action is played in the rotation to locking part.
The described axis of guide 51 is provided with mounting plane 513, described mounting plane 513 through the first bearing 1 with it is spacing
Driving member 4 is connected.Motion of the axis of guide on the first bearing is easy in the setting of mounting plane so that axis of guide stable movement,
It is easy to be connected with spacing driving member simultaneously, it is easy for installation.
