Operation rotating shaft 202 is inserted in after 3 linkage pieces 211 and keeps direction consistent, 3 that 3 set bars 212 are inserted on linkage board 203
Individual hole, then the direction as shown in exploded view in Fig. 6 put positioning sleeve 209, guide plate 210, positioning sleeve 209 and just constitute cover plate successively
And operation rotating shaft 12；Finally pedestal 11 and cover plate and operation rotating shaft 12 are closed up, operation rotating shaft 202 is penetrated steel plate 101U types bottom
In 3 positioning holes on plate and return pin 106 is located in the circular arc type slotted eye of guide plate 210, with 8 fixed bases of attachment screw 13
Seat 11 and cover plate and operation rotating shaft 12, interlock is completed.
Manner of execution of the present invention is as follows：The device being completed is in released state, and now the top of interlocking latch 103 does not emit
Go out steel plate 101；Such as Fig. 7,4 insertion operation rotating shaft of door lock, 202 positive hexagonal groove hole, along the rectangular channel on steel plate 201 to the left
Alignment pin arm-tie 204 is pulled, alignment pin 208 is exited from the hole of operation rotating shaft 202, now rotating door lock 4 makes operation rotating shaft
202 rotate 90 degree, due to the effect of linkage piece 211, set bar 212 and linkage board 203, protect 3 operation actions of rotating shaft 202
Hold unanimously, so guide plate 210 also rotates 90 degree simultaneously, 2 interlocking pin plates 104 are pushed up up and down along guiding steel pin 102 respectively
Rise, so, the interlocking latch 103 on interlocking pin plate 104 stretches out steel plate 101, stretches into perforate of the door-plate about 3 at flanging
In, door-plate 3 is pinned, decontrols alignment pin arm-tie 204, under the effect of locating pin spring 207, alignment pin 208 turns again insertable into operation
In the obturator hernia of axle 202, now, interlock is in blocking (such as Figure 10)；Operating procedure is unlocked as the anti-of lock operation
To operation, be now crimped on the return pin 106 of interlocking pin plate 104 makes connection by the circular arc type slotted eye drive of guide plate 210
Locked pin plate 104 drives interlocking latch 103 to reset, and unblock is completed.
Present invention accomplishes the demand strengthened different in width cabinet door, lifting cabinet door internally failure when protective capacities,
Reach in national standard switch cubicle in normal operation position and can be provided for the personnel near switch cubicle when internally there is arc event
The requirement of protection；Cabinet overall appearance, convenient operation are not destroyed again simultaneously.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
