Embodiment
Referring to the drawings, a kind of power distribution cabinet interlocking mechanism, including the door hook 8 being arranged on Xiamen, it is located in cabinet side wall
The breaking-closing operating mouth 10 opened up above Xiamen, disconnecting switch a action bars 3 are placed in breaking-closing operating mouth 10；
Described door hook 8 includes upper and lower breach, valve latch hook 11 is set positioned at the top of upper breach, positioned at lower breach
Lower section Xiamen latch hook 6 is set, described valve latch hook 11 is arranged in the bottom of valve blocking lever 9, the described cloth of Xiamen latch hook 6
The bottom of Xiamen blocking lever 5 is placed in, frame plate 12 is fixed with the side wall of Xiamen on cabinet, limiting plate is set on frame plate 12,
First spacing hole is set on limiting plate at valve blocking lever 9, it is spacing that setting second at Xiamen blocking lever 5 is located on limiting plate
Hole, valve blocking lever 9, which is located above limiting plate, is fixed with the first stage clip, and the lower end of the first stage clip is fixed on the first spacing hole,
Xiamen blocking lever 5, which is located above limiting plate, is fixed with the second stage clip 13, and the lower end of the second stage clip 13 is fixed on the second spacing hole,
The top of valve blocking lever 9 is provided with slide plate 1, and described slide plate 1 is extended at breaking-closing operating mouth 10, and slide plate 1 is to divide-shut brake
The outside of gathering hole 10 is extended with lock core switch block, and the top of Xiamen blocking lever 5 is extended at action bars 3, under being located on action bars 3
The apical position of couplet on the door locking bar 5 is provided with Xiamen latch hook cam bit 4；
The rod end that action bars 3 is located at breaking-closing operating mouth 10 opens up lock core hole, and handle 2 is inserted in described lock core hole and driven
Lock core synchronous axial system.
Further, described limiting plate includes upper and lower limiting plate, and first, second described spacing hole is arranged in lower limit
On the plate of position.So ensure the stable guiding of Xiamen blocking lever 5, valve blocking lever 9 so that Xiamen blocking lever 5, valve blocking lever 9
Slided along first, second spacing hole is firm.
Preferably, the lower section of described breaking-closing operating mouth 10 opens up chute, and the lock core switch block of slide plate 1 is arranged along chute
Direction slides up and down.
With reference to Fig. 1,2, the structure of handle 2 of the present invention is eliminated in wherein Fig. 2.
Disconnecting switch a separating brake is performed, that is, closes the operating procedure of disconnecting switch：
Lock core switch block is pressed downwards, and lock core switch block drive slide plate 1 is descending, and breaking-closing operating mouth 10 is opened, and exposes operation
The lock core hole of the rod end of bar 3, enter handle 2, rotate counterclockwise handle 2 to lock core hole interpolation, handle 2 drives what is be hinged with action bars 3
Disconnecting switch a carries out sub-switching operation, meanwhile, the Xiamen latch hook cam bit 4 on action bars 3 rotates will to the summit of its cam
Xiamen blocking lever 5 pushes, and so drives the Xiamen latch hook 6 of the bottom of Xiamen blocking lever 5 to stop in the lump to bottom offset, Xiamen latch hook 6
The hook resistance of 8 times breach of hook on the door.Handle 2 is pulled up, slide plate 1 is pushed up go back to original position by valve blocking lever 9 because the first stage clip acts on,
While slide plate 1 closes breaking-closing operating mouth 10 so that the valve latch hook 11 of the bottom of valve blocking lever 9 departs from door hook 8.This
When, the upper and lower breach of door hook 8 can open cabinet Xiamen without resistance is hooked.
Disconnecting switch a combined floodgate is performed, that is, opens the operating procedure of disconnecting switch：
Slide plate 1 is pushed, handle 2 is inserted, carries out the closing operation that turns clockwise, Xiamen latch hook cam bit 4 is rotated to cam
Minimum point, release the extruding to Xiamen blocking lever 5, Xiamen blocking lever 5 is because the effect of the second stage clip 13 pops into position, Xiamen
The Xiamen latch hook 6 of the bottom of blocking lever 5 shifts up in the lump, carries out the hook resistance of 8 times breach of hook on the door.Pull up handle 2, valve connection
Slide plate 1 is pushed up to peak, slide plate 1 and caused while closing breaking-closing operating mouth 10 due to the effect of the first stage clip by locking bar 9
Valve latch hook 11 departs from door hook 8.Now hook 8 has hooked resistance and its Xiamen is not opened Xiamen latch hook 6 on the door, completes to close
Lock, cabinet door can not open.
By existing disconnecting switch point, close a floodgate is transferred to away under a powered secondary chamber in the operating room of middle door
On the cabinet wall of door upside, eliminate the potential safety hazard of disconnecting switch divide-shut brake, and by disconnecting switch point, close a floodgate and Xiamen is opened
Seco is locked, that is, during the opening of Xiamen, disconnecting switch separating brake, when Xiamen is closed, disconnecting switch is closed a floodgate.Operating personnel pass through Xiamen
Switch i.e. can determine whether and determine disconnecting switch opening and closing state, facilitate being held to disconnecting switch disconnecting link division for operating personnel
OK.
