LOOKING MECHANISM FOR HATCH FOR USE OF VEHICLE VENTILATION AND EMERGENCY ESCAPE

摘要

PURPOSE: A locking mechanism is provided to allow the hatch to be firmly fixed for vehicle ventilation at ordinary time and easily stripped at emergency, while preventing damage to the hatch during repair and maintenance. CONSTITUTION: A locking mechanism comprises a hatch having a size sufficient to cover an opening of the vehicle; a hinge link device connected between a first bracket fixed to the bottom of the hatch and a second bracket fixed to the inner wall of the opening of the vehicle; a lever(200) having an end supported to be rotatable at the center of the first bracket, and coupling holes(203) spaced apart from a support hole(201); a plurality of rods(210) coupled to coupling holes of the lever so as to move in an opposite direction; and an intermittent support unit(300) fixed to both sides of the first bracket so as to support the first bracket and the hatch. The intermittent support unit includes a stopper(310) coupled to the hatch and has a stopper opening(311) formed at the center of the stopper; and a support member(320) to be coupled to the first bracket and which has an insertion opening(321) for insertion of the stopper and an insertion opening(323) for insertion of the rod.
