State and connect the other end and the described gag lever post of sheet and fix and be connected.
Alternatively, described connection sheet is provided with bar shaped notch；Described rotating mechanism is slidably connected to described company by bolt
Bar shaped notch in contact pin.
Alternatively, described rotating mechanism is provided with operation rod aperture.
Compared with prior art, the embodiment of the present application has the advantages that
This utility model has reasonable in design, and interlocking protection is reliable；After drawer unit is extracted out, do not exist and closing a floodgate
Unit can be advanced situation under state, it is therefore prevented that arc short-circuit occurs；Additionally advance and after breaker closing when drawer unit, connection
Lock construction inserts and forms double shielding in low voltage drawing-out switching carbinet framework, it is therefore prevented that extraction to unit under "on" position,
Short-circuit conditions is avoided to occur equally.

Detailed description of the invention
For making the purpose of the application, technical scheme and advantage clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described by corresponding accompanying drawing.
It it is the structural representation of a kind of low voltage drawing-out switching carbinet interlocking mechanism shown in Fig. 1.As it is shown in figure 1, described interlocking
Mechanism includes rotating mechanism 1, connects sheet 2 and gag lever post 3；One end of described connection sheet is slidably connected with described rotating mechanism, institute
State and connect the other end and the described gag lever post of sheet and fix and be connected.
As an embodiment of the present utility model, described connection sheet is provided with bar shaped notch 7；Described rotating mechanism passes through
Bolt is slidably connected to the bar shaped notch on described connection sheet.
As an embodiment of the present utility model, described gag lever post connects by bolt and described connection sheet are fixing.
As an embodiment of the present utility model, described rotating mechanism is provided with operation rod aperture 8, in order to by rotating mechanism set
On drawer unit breaker operator bar 6.
It is to be appreciated that interlocking mechanism of the present utility model is enclosed within drawer unit breaker operator bar, rotating mechanism
Rotate along with chopper on/off switch, drive gag lever post to move up and down, drawer unit drain pan 4 and drawer unit compartment simultaneously
Base plate 5 is equipped with hole 9, location, and gag lever post shuttles back and forth in the hole, location of drawer unit drain pan and drawer unit compartment base plate,
Hole, location is used for drawer unit positioning and locking, and hole, these two location coincides with the upper and lower when the situation that drawer unit is the most in place.
Further, drawer unit just can carry out closing operation in the case of the most in place.On the one hand at drawer unit
In the case of closing a floodgate outside switch cubicle, during drawer unit advances, this utility model interlocking mechanism spacing
Bar can be blocked by drawer unit compartment base plate, causes drawer unit cannot be pushed further into the stationary contact on switch cubicle and contacts；
On the other hand, in the case of drawer unit is the most in place, at the bottom of the hole, location on drawer unit drain pan and drawer unit compartment
The hole, location of plate is misaligned, if the operating mechanism of chopper is carried out closing operation, carries out the mistake rotated at breaker operator bar
Cheng Zhong, the gag lever post in interlocking mechanism can move down, when touching drawer unit compartment base plate, it is impossible to move further downward
Dynamic, thus limit the rotation of breaker operator bar, chopper is unable to reach "on" position.Only the most complete at drawer unit
Just can carry out closing operation in the case of in place, thus avoid push-and-pull drawer unit after closing operation, have in lower end
Arc short-circuit is there is under load condition.
Further, after drawer unit carries out closing operation, under the effect of gag lever post, drawer unit cannot be carried out push-and-pull
Mobile, improve the security and stability that GCK cabinet runs.Because, under "on" position, the gag lever post of interlocking mechanism runs through drawer unit
Hole, location on drain pan and drawer unit compartment base plate, due to the restriction in drawer unit compartment base plate upper limit hole, prevents connection
The movement of latch mechanism gag lever post, thus the position of drawer unit is limited, it is impossible to move.Therefore drawer unit is worked as
Under complete seated position after closing operation, drawer unit will not arbitrarily advance and pull out.
As shown in Figures 2 and 3, interlocking mechanism when separating brake, gag lever post just through the hole, location on drawer unit drain pan, and
Being not passed through the hole, location on drawer unit compartment base plate, specifically, interlocking mechanism is under gate-dividing state, gag lever post does not reaches permissible
Running through the length in the hole, location of drawer unit compartment base plate 5, drawer unit can safe pushing in static contact；
As shown in Figure 4 and Figure 5, interlocking mechanism is when closing a floodgate, and gag lever post is also cross drawer unit drain pan and drawer unit
Hole, location on compartment base plate, carries out spacing to drawer unit, specifically, when closing a floodgate, drawer unit breaker operator bar energy
Enough driving rotating mechanism to rotate together, rotating mechanism drives gag lever post to move up and down, at drawer unit drain pan 4 by connecting sheet
Shuttle back and forth with in the hole, location on drawer unit compartment base plate 5.If now drawer unit being carried out push-and-pull, due to compartment bottom plate hole
Limiting, gag lever post cannot be carried out mobile, and the position of drawer unit there will be locking state, and interlocking mechanism inserts low pressure draw-out type and opens
Close and form double shielding in cabinet frame work, it is therefore prevented that extraction to unit under "on" position, avoid short-circuit conditions to occur equally；If
Drawer unit is after GCK low-voltage cabinet shell carries out closing operation more in place, now because of interlocking mechanism in drawer unit is carried out cabinet
Gag lever post lean out compartment base plate, by compartment backplane card outside cabinet, drawer unit cannot advance, and prevents under "on" position
Drawer unit advances, it is to avoid arc short-circuit occurs under there is load condition lower end.
During it is to be appreciated that gate-dividing state should be at chopper when installing interlocking mechanism, rationally select interlocking machine
The setting angle of structure is installed.Interlocking mechanism is under breaker open operation state, and gag lever post is not because the factor of the anglec of rotation can
Piercing in the hole, location of drawer unit compartment base plate, drawer unit can safe pushing in static contact.
Obviously, described embodiment is only some embodiments of the present application rather than whole embodiments.Based on this Shen
Embodiment in please, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, broadly falls into the scope of the application protection.
