After the lower door 8 is opened, the lower door touch structure has no touch force, the upper door lock pin 14 pushes the movable platen 12 to move upwards under the action of the top pressure spring 11, and then the upper door lock pin 14 is pushed to move upwards, so that the upper door lock pin 14 is separated from the lock hole 18.
In this embodiment, there are two brackets 1, which are disposed at two sides of the ejector rod 5 at an interval, there are two corresponding transmission levers, the lever plates 15 of the two transmission levers are force-fit with the same ejector rod 5, and there are two push rods 10.
The lower door 8 is fixed with a striking plate 7 which is used for pushing, rolling and swinging downwards when the lower door 8 is closed, the section of the striking plate 7 is U-shaped, and the length of two arms of the U-shaped striking plate can ensure the rotation amplitude of the crank arm 4 when the lower door 8 is closed.
The working principle is as follows: when the upper and lower door interlocking device 17 is used for door closing operation, the upper door 9 is closed firstly, the push rod 10 pushes the transmission stop block 2 to move backwards, then the lock hole 18 on the push rod 10 corresponds to the penetrating hole 103, at the moment, the lower door 8 is not closed, the upper door lock pin 14 keeps the upward movement trend under the action of the jacking spring 11, then the lower door 8 is closed, the collision plate 7 drives the driving roller 6 to swing downwards, the other end of the crank arm 4 swings upwards to drive the ejector rod 5 to move upwards, the ejector rod 5 drives the lever plate 15 to rotate, and the upper door lock pin 14 overcomes the acting force of the jacking spring 11 and is inserted downwards into the lock hole 18 to realize locking, so that the upper door 9 is ensured to be locked; if the lower door 8 is directly closed when the upper door 9 is not closed, at this time, because the transmission stop block 2 is not removed, and the penetrating hole 103 is blocked, the upper door lock pin 14 which moves downward under the action of the ejector rod 5 cannot move continuously after being pressed against the transmission stop block 2, so that the crank arm 4 cannot rotate continuously, and the lower door 8 cannot reach a door closing position, thereby the lower door 8 cannot be closed.
When the upper and lower door interlocking device 17 is used for door opening operation, the lower door 8 is opened firstly, the ejector rod 5 has no upward driving force at the moment, under the self-weight action of the jacking spring 11 and the ejector rod 5, the lever plate 15 rotates reversely to drive the ejector rod 5 to move downwards, the upper door lock pin 14 moves upwards to be separated from the lock hole 18, at the moment, the interlocking device 17 is unlocked, the upper door 9 can be directly opened, the push rod 10 moves out of the accommodating groove 102, and meanwhile, the transmission stop block 2 returns to the original position under the action of the reset spring to realize the door opening operation; if the upper door 9 is opened before the lower door 8 is not opened, the upper door 9 is locked because the upper door lock pin 14 is locked and matched with the lock hole 18, and cannot be directly opened at all.
In the second embodiment of the switch cabinet of the present invention, under the condition that the other structure of the first embodiment is not changed, the bracket can be made into an E shape as shown in fig. 21, and only the opening direction of the accommodating groove is required to be ensured to face the push rod, or two plates with a U-shaped groove with an opening extending along the horizontal direction are directly overlapped to form the bracket.
In a third embodiment of the switch cabinet of the present invention, in the case that the other structure of the first embodiment is not changed, the bracket may be configured as a U-shaped structure with only the receiving groove as shown in fig. 22, and the reset mechanism is directly installed at the upper end of the bracket.
In a fourth embodiment of the switch cabinet, under the condition that other structures of the first embodiment are not changed, the crank arm is not arranged, the ejector rod 5 vertically guides and moves in the supporting plate, the lower end of the ejector rod 5 is provided with an insertion long hole extending up and down, an insertion block which is in insertion fit with the insertion long hole is arranged at the corresponding position of the lower door, the upper end surface of the insertion block is of a slope-shaped structure with a lower back and a higher front, and the ejector rod continuously moves up by continuously inserting the insertion block into the insertion long hole of the ejector rod in the closing process of the lower door so as to push the upper door lock pin to act.
In other embodiments, the connecting rod mechanism can be arranged in a connecting rod structure that the input end is hinged with the crank arm, and the output end is directly hinged with the upper door lock pin, at the moment, the lock body is arranged on the upper side of the connecting rod in an inverted mode, and the upper door and the lower door can be interlocked.
In other embodiments, the interlocking mechanism is also applicable to the cabinet structure with left and right doors under the condition that other structures of the first embodiment are not changed; only one support can be arranged, and the return spring can be directly sleeved on the T-shaped lower half part of the upper door lock pin.
