Specifically, two vertical grooves are formed in the lock plate 3, two rivets are arranged on the guide seat 4, and the two rivets penetrate through the two vertical grooves respectively, so that the lock plate 3 moves up and down along the guide seat 4.
The utility model discloses a cubical switchboard door interlocking principle as follows:
the grounding operation shaft 2 can rotate back and forth at a closing station and an opening station,
the first state: the grounding operation shaft 2 is located at a closing station, the locking plate 3 moves downwards to a closing station, and as shown in fig. 7, the locking plate 3 can move up and down, namely, move between the opening station and the closing station. When the locking plate 3 moves down to the station of closing the door, the locking lever 32 lower extreme and the 6 lockings of cabinet door, and cabinet door 6 is closed, and at this moment, baffle 31 does not shelter from 2 connecting portions of ground connection operation axle, consequently, can operate 2 rotations of ground connection operation axle to the separating brake station, but, this moment cabinet door 6 is closed, and operating personnel has avoided touching the high-pressure position in the cabinet, and the security can be ensured.
And a second state: the locking plate 3 moves downwards to the door closing station, and the grounding operation shaft 2 is operated to rotate to the opening station, namely as shown in fig. 6; locking plate 3 moves down to the station of closing the door, drive gag lever post 5 and be clockwise rotation, the butt portion of gag lever post 5 is located the separating brake station, limiting plate 21 butt mouth at this moment has also rotated to the separating brake station, the butt portion of gag lever post 5 is withstood to limiting plate 21's butt mouth, in order to restrict gag lever post 5 and be anticlockwise rotation, thereby just also restricted locking plate 3 and done the rebound (because locking plate 3 shifts up and need drive gag lever post 5 and do anticlockwise rotation), therefore, just also ensured when ground connection operating axis 2 is in the separating brake station, locking plate 3 can't shift up, cabinet door 6 can't be opened promptly, and the security has been promoted.
And a third state: when the grounding operation shaft 2 is at the closing station, the locking plate 3 moves up to the door opening station, as shown in fig. 8.
At this time, the lower end of the lock lever 32 is separated from the cabinet door 6, and the cabinet door 6 can be opened, but at this time, the baffle 31 moves upward along with the lock plate 3, and the baffle 31 is stopped at the front side of the connecting portion of the grounding operation shaft 2, as shown in fig. 2, so that the grounding operation shaft 2 cannot be operated to the opening station at this time, and even if the cabinet door 6 is opened, the grounding operation shaft 2 cannot perform the opening operation at this time, so that danger is not generated, and the safety is improved.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
