In the mechanical interlocking structure between the movable wire inlet cabinet and the fixed metering cabinet, the front cabinet door 1100 can be closed only by closing the rear cabinet door 1200 to press down the first rear door connecting rod 210 and prying the front door interlocking stop lever 230 to retract through the front door interlocking lever 220, and the metering cabinet front door pressing rod 130 in the front door safety mechanism 100 needs to be pressed down through closing the front cabinet door 1100 to shrink the wire inlet cabinet stop lever 120 through the rotation of the front door L-shaped connecting piece 110, so that the wire inlet cabinet 2000 can be pushed to be connected with the metering cabinet 1000.
When the wire inlet cabinet 2000 is installed in a pushing connection manner, the rear cabinet door 1200 needs to be closed first, and when the rear cabinet door 1200 is closed, the end of the first rear door link 210 is pressed down through one side of the rear cabinet door 1200, so that the first rear door link 210 slides along the side wall of the inner side of the metering cabinet 1000, the front door interlocking lever 220 located at one side of the front door is pushed by the other end of the first rear door link 210, and the front door interlocking lever 220 rotates around the hinge point to pry the front door interlocking stop lever 230 located at the other end of the front door interlocking lever 220 to shrink.
When the rear cabinet door 1200 is not closed, the first extension spring 241 is not pulled open, and at this time, the front door interlock bar 230 protrudes to the rear side of the front door L-shaped link 110 on the front door safety mechanism 100, so that the rotation of the front door L-shaped link 110 can be blocked.
After the rear cabinet door 1200 is closed, the front door interlock lever 220 is rotated to retract the front door interlock bar 230, opening the rear space of the front door L-shaped link 110, so that the front door L-shaped link 110 can be rotated about the hinge point, at which time the front cabinet door 1100 can be closed.
Closing the front cabinet door 1100, one side of the front cabinet door 1100 presses down the metering cabinet front door pressing rod 130, the metering cabinet front door pressing rod 130 moves backwards under pressure and contracts towards the inside of the metering cabinet 1000, so that the front door L-shaped connecting piece 110 is driven to rotate, the wire inlet cabinet stop lever 120 is driven to contract to enter the side of the metering cabinet 1000, and blocking of the right wire inlet cabinet 2000 is avoided.
When the front cabinet door 1100 is not closed, the wire inlet cabinet stop lever 120 transversely penetrates into the side of the right wire inlet cabinet 2000 from the side of the metering cabinet 1000 to block the wire inlet cabinet 2000, so that the wire inlet cabinet 2000 is prevented from being pushed in when the front cabinet door 1100 is not closed.
Therefore, after the rear cabinet door 1200 is closed and the front cabinet door 1100 is closed, the process of pushing the wire inlet cabinet 2000 can be standardized through the front door safety mechanism 100 and the rear door safety mechanism 200, and the next step cannot be completed before any step is not completed, so that the connection and installation of the wire inlet cabinet can be standardized, and the connection safety can be better ensured.
During the process of pushing the wire inlet cabinet 2000 into connection with the metering cabinet 1000, the side surface of the wire inlet cabinet 2000 triggers the wire inlet cabinet pressure point 500.
In the pushing process of the wire inlet cabinet 2000, the wire inlet cabinet pressing rod 520 in the wire inlet cabinet pressing point 500 is pressed down, so that the joint of the wire inlet cabinet pressing rod 520 and the pressing point tilting rod 530 hinged with each other is jacked outwards, and the other end of the pressing point tilting rod 530 is pressed down, so that the front cabinet door lock rod 540 can be driven to move transversely to be inserted into the side surface of the front cabinet door 1100, and the front cabinet door 1100 is locked.
When the front door lock lever 540 moves laterally, the front door L-shaped locking connector 310 can be driven to rotate around the hinge point, the second rear door link 410 is pushed to slide along the inner side wall of the metering cabinet 1000 by the other side of the front door L-shaped locking connector 310, and the rear door lock mechanism 400 is pushed to lock the rear door 1200 by the other end of the second rear door link 410.
The distal end of the second rear door link 410 pushes the rear door L-shaped locking connector 411 to rotate around the hinge point, and the other end of the rear door L-shaped locking connector 411 pulls the rear door lock lever 420 to slide laterally so as to be inserted into the side wall of the rear door 1200, thereby locking the rear door 1200.
In this interlocking structure of measurement cabinet 1000 and inlet wire cabinet 2000, when carrying out the propulsion of inlet wire cabinet 2000 and connect, need once close back cabinet door 1200, close before the cabinet door 1100 after can impel inlet wire cabinet 2000 in order to connect, and after inlet wire cabinet 2000 impels and accomplish, can accomplish the automatic locking of front cabinet door 1100 and back cabinet door 1200 through front door locking mechanism 300 and back door locking mechanism 400, can optimally ensure the connection and the safe in utilization of cubical switchboard.
While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the invention, the scope of which is defined by the claims and their equivalents.
