When by the upper backup pad 113 stop can not continue to turn clockwise.Institute is can be inserted into when second projection 153 is rotated counterclockwise
State in through hole 133.
Drawer-type switch cabinet interlocking and middle-low voltage switch cabinet in the present invention, extraction structure drawer is arranged on by interlocking
On, distribution component is opened or closed by the extraction or push-in control circuit of drawer.Set two jacks respectively with the on cabinet
One latch, the second latch are engaged, and lock drawer and cabinet when in the first latch and the second latch insertion jack.Interlocking will take out
Drawer is inserted in the jack on cabinet respectively with cabinet lock timing, the first latch and the second latch, in clamp insertion neck.Now by
In the limitation of clamp, pushing meanss can not be promoted.When needing to extract out drawer, rotatable handle drives rotating disk and the rotation of the first projection,
First projection promotes the second latch to rise when rotating, the second latch is exited when rising out of cabinet jack, while clamp is from card
Exited in groove, now pushing meanss can be promoted.Pushing meanss support the first latch when promoting make after the rising of the first latch from cabinet
Exited in the jack of body, release the locking of drawer and cabinet.In released state, the first resetting means and the second resetting means have
It is elastic.When needing locking, the thrust to pushing meanss is released, pushing meanss reset in the presence of the second resetting means, solved
Except the power of supporting to the first latch, the first latch is resetted in the jack for reinserting cabinet in the presence of the first resetting means.
Reversely rotating handle drives rotating disk and the second projection to reversely rotate, and insertion cabinet inserts after the second projection the second latch of compressing declines
In hole.First latch and the second latch lock drawer and cabinet.
Upper and lower, left and right in the present embodiment, with accompanying drawing 4 be clockwise, counterclockwise reference, be more clearly description originally
Relative concept used in invention, and it is not construed as limiting the scope of claims limitation.
Embodiment in the present invention is only used for that the present invention will be described, and is not construed as limiting the scope of claims limitation,
Other substantial equivalent replacements that those skilled in that art are contemplated that, all fall in the scope of protection of the present invention.
