This utility model relates to the field of low-
voltage switchgear technology, specifically an
interlocking mechanism for a movable drawer unit and the movable drawer unit itself. The
interlocking mechanism includes a position
interlocking mechanism, comprising a position interlocking drive plate and a movable portion position
locking plate. The movable portion position
locking plate is located on the back of the movable drawer unit and is fixed to the movable portion. The position interlocking drive plate is positioned by embedding a positioning element into a corresponding position positioning hole on the movable portion position
locking plate. The fixed and movable portions of the movable drawer unit are interlocked through the aforementioned interlocking mechanism. The advantages are: the interlocking mechanism has complete functions, low structural cost, small space occupation, and enables unit
miniaturization; the use of T-shaped sliding columns and guide rails for push-guided limiting reduces the precision requirements of sheet
metal parts
processing, lowers costs, solves push-up failures, controls the upward tilting of the rear of the movable portion, and also increases the internal width of the unit.
