The present invention relates to a door closing device which can simply be installed in a door frame without damage to wall portions around the door frame, thereby having low installation costs; reduces a number of components and has a simple structure, thereby drastically saving manufacturing costs and being easily used while having excellent durability; and moreover, uses an independent alarm type sensor having low manufacturing costs and being easily repaired as a fire sensing unit, thereby largely enhancing reliability for a fire sensing function of the fire sensing unit. The present invention comprises: a support unit; a fixated unit provided on a rear side of the support unit to be fixated to the door frame; a door opening maintenance unit provided on a front side of the door, and touching the door in an opened state provided on an inner side of the door frame to maintain an opened state of the door; and a control unit releasing the door opening maintenance state of the door opening maintenance unit to control the door opening maintenance unit to close the door.
본 발명은 도어 폐쇄장치에 관한 것으로서, 문틀 주변의 벽체를 훼손하지 않고 상기 문틀에 간단하게 설치할 수 있어 설치비용이 저렴할 뿐만 아니라 구성요소의 개수가 적음과 더불어 구조가 간단하여 제조단가가 현저히 절감될 수 있음은 물론 내구성이 우수하면서도 사용법이 쉽고, 나아가 화재감지부로서, 제조단가가 낮고, 제품수리가 용이한 단독경보형감지기를 사용함으로서, 상기 화재감지부의 화재감지기능에 대한 신뢰도가 크게 향상될 수 있는 효과가 있다.
