Drawer unit with closing interlock mechanism

Abstract

This utility model relates to the field of low-voltage switchgear technology, and in particular to a closing interlocking mechanism for a drawer unit. The closing interlocking mechanism includes a closing interlocking bracket, a closing interlocking traction plate, and a closing interlocking locking plate. The closing interlocking traction plate has operating holes for the opening and closing shafts, allowing the opening and closing shafts to be inserted and causing the closing interlocking traction plate to rotate synchronously with the inserted opening and closing shafts. The closing interlocking traction plate drives the closing interlocking locking plate downwards to perform the closing interlock. The closing interlocking traction plate has a circular boss, which is coaxial with the operating holes for the opening and closing shafts. The closing interlocking bracket has a shaft hole that mates with the circular boss, allowing the circular boss to be embedded in the shaft hole for rotational support of the closing interlocking traction plate and the opening and closing shafts. The advantages are: by using the engagement of the circular boss and the shaft hole, only the closing interlocking traction plate needs to be manufactured in different specifications to accommodate opening and closing shafts of different thicknesses, while the closing interlocking bracket can be universal, simplifying the production process and reducing costs.
