The present invention relates to a multi-point lock system for fire doors, wherein the multi-point lock system for a fire door has a structure improved for a main locker to be assembled by an engagement structure of an inner race gear and a pinion module, such that an assembly process is greatly reduced by no bolting coupling and each component structure is simplified to reduce a manufacturing cost. The system comprises a main body case (10), a pinion module (20), a main locker (30), upward and downward rack modules (40)(40'), and upward and downward multi-lockers (50)(50') and has the main body case installed to be switched by 180° degrees in a forward and backward direction or vertical direction to let a withdrawing direction of the main locker switch by 180°, thereby applying to left or right open fire doors for a universal purpose.
본 발명은 방화문용 멀티 포인트락 시스템에 관련되며, 이때 방화문용 멀티 포인트락 시스템는 내륜기어와 피니언모듈의 치합 구조에 의해 메인록커가 조립되도록 구조 개선되어 무볼팅 결합으로 조립 공정이 대폭 감축됨과 더불어 각각의 부품 구조가 단순화되어 제조원가가 절감되고, 본체케이스를 전후 또는 상하방향으로 180° 전환 설치하여, 메인록커의 인출방향을 180° 전환하는 방식으로 좌, 우측 개방형 방화문에 범용으로 적용할 수 있도록 본체케이스(10), 피니언모듈(20), 메인록커(30), 상, 하향 래크모듈(40)(40'), 상, 하향 멀티록커(50)(50')을 포함하여 주요구성으로 한다.
