Accompanying drawing explanation
Fig. 1 is the perspective view of the present invention；
Fig. 2 be the present invention with disconnecting switch coordinate figure.
Detailed description of the invention
Referring to the drawings, a kind of power distribution cabinet interlocking mechanism, including the door hook 8 being arranged on Xiamen, cabinet sidewall is positioned at
The breaking-closing operating mouth 10 that Xiamen is opened above, the action bars 3 of disconnecting switch a is placed in breaking-closing operating mouth 10；
Described door hook 8 includes upper and lower breach, and be positioned at breach is provided above valve latch hook 11, is positioned under lower breach
Side arranges Xiamen latch hook 6, and described valve latch hook 11 is arranged in the bottom of valve blocking lever 9, and described Xiamen latch hook 6 is arranged in
The bottom of Xiamen blocking lever 5, cabinet is fixed with frame plate 12 on the sidewall of neighbouring Xiamen, frame plate 12 arranges limiting plate, spacing
It is positioned at valve blocking lever 9 on plate and the first spacing hole is set in place, limiting plate is positioned at Xiamen blocking lever 5 and arranges second in place
Spacing hole, valve blocking lever 9 is positioned at the top of limiting plate and is fixed with the first stage clip 10, and the lower end of the first stage clip 10 is fixed in the first limit
On hole, position, Xiamen blocking lever 5 is positioned at the top of limiting plate and is fixed with the second stage clip 13, and the lower end of the second stage clip 13 is fixed in the second limit
Position hole on, the top of valve blocking lever 9 is provided with slide plate 1, and described slide plate 1 extends at breaking-closing operating mouth 10, slide plate 1 to
Being extended with lock core switch block outside breaking-closing operating mouth 10, it is in place that the top of Xiamen blocking lever 5 extends to action bars 3 institute, this position
Install and be equipped with Xiamen latch hook cam bit 4；
Action bars 3 is positioned at the rod end of breaking-closing operating mouth 10 and offers lock core hole, and handle 2 inserts band movable lock core in described lock core hole
Synchronous axial system.
Further, described limiting plate includes that upper and lower limiting plate, first, second described spacing hole are arranged in lower limit
On the plate of position.So ensure Xiamen blocking lever 5, the stable guiding of valve blocking lever 9 so that Xiamen blocking lever 5, valve blocking lever 9
Slide along first, second spacing hole is firm.
Preferably, chute is offered in the lower section of described breaking-closing operating mouth 10, and the lock core switch block of slide plate 1 is arranged along chute
The upper and lower sliding in direction.
In conjunction with Fig. 1,2, Fig. 2 wherein eliminates handle 2 structure of the present invention.
Perform the separating brake of disconnecting switch a, namely close the operating procedure of disconnecting switch:
Pressing downwards lock core switch block, lock core switch block drives slide plate 1 descending, and breaking-closing operating mouth 10 is opened, and exposes action bars 3 bar
The lock core hole of end, is inserted into handle 2, rotary handle 2 counterclockwise to lock core hole, and handle 2 drives keep apart hinged with action bars 3
Closing a and carry out sub-switching operation, meanwhile, the summit that the Xiamen latch hook cam bit 4 being positioned on action bars 3 rotates to its cam is by the lower couplet on the door
Locking bar is pressed for 5 times, so drives the Xiamen latch hook 6 bottom Xiamen blocking lever 5 in the lump to bottom offset, and Xiamen latch hook 6 stops opposite house and hangs
Hook the hook resistance of 8 times breach.Pulling up handle 2, valve blocking lever 9 acts on due to the first stage clip 10, by slide plate 1 fight back in situ, and slide plate 1
While closing breaking-closing operating mouth 10 so that the valve latch hook 11 bottom valve blocking lever 9 departs from door hook 8.Now, door
The upper and lower breach of hook 8 all without hooking resistance, just can open cabinet Xiamen.
Perform the combined floodgate of disconnecting switch a, namely open the operating procedure of disconnecting switch:
Lower pressure slide plate 1, inserts handle 2, and carry out turning clockwise closing operation, and Xiamen latch hook cam bit 4 rotates to cam
Low spot, releases the extruding to Xiamen blocking lever 5, and Xiamen blocking lever 5 pops into position due to the effect of the second stage clip 13, lower gate interlock
The Xiamen latch hook 6 of bar 5 bottom shifts up in the lump, carries out the hook resistance of 8 times breach of opposite house hook.Pull up handle 2, valve blocking lever
9 due to the effect of the first stage clip 10, is pushed up by slide plate 1 to peak, and slide plate 1 makes while closing breaking-closing operating mouth 10 to live
Door lock hook 11 departs from door hook 8.Now Xiamen latch hook 6 opposite house hook 8 has hooked resistance makes its Xiamen to open, and completes to close a floodgate,
Cabinet door cannot be opened.
By existing disconnecting switch point, closing a floodgate is positioned at the operating room of middle door and is transferred to away under a charged secondary chamber
On cabinet wall on the upside of Men, eliminate the potential safety hazard of disconnecting switch divide-shut brake, and by disconnecting switch point, close a floodgate and the opening of Xiamen
Seco is locked, and when namely Xiamen is opened, disconnecting switch separating brake, when Xiamen is closed, disconnecting switch is closed a floodgate.Operator pass through Xiamen
Switch i.e. can determine whether and determine disconnecting switch opening and closing state, facilitate operator disconnecting switch disconnecting link deciliter is held
OK.
