The present invention relates to a protective cover for a cylinder of opening and closing a fire door. The protective cover in which a cylinder is inserted and installed removes and blocks a gap and an open part in order for a flame not to infiltrate into the fire door when a fire breaks out. Also, the protective cover for a cylinder of opening and closing a fire door improves convenience by facilitating connection of the protective cover and a reinforcing unit installed in the fire door. A sheet which is treated by a sheet metal work is integrally bent in order for the durability of the protective cover to be improved so that the opening of the fire door is not difficult as a form of the protective cover is changed due to high heat when the fire breaks out. An installation space is installed inside while a front side is open in order for the cylinder to be inserted and fixed. An installation hole penetrated is individually formed on both sides, and a pair of door handles operating the cylinder installed inside is connected to the cylinder through the installation hole. The front side of the protective cover is fixed and installed to the inner surface of the reinforcing unit. So, the protective cover is formed by being bent.
본 발명은 방화문 개폐 실린더용 보호커버에 관한 것으로서, 실린더가 삽입 설치되는 보호커버를 화재시 화염이 방화문 내부로 침투하지 못하도록 개방부분과 틈새를 제거하여 차단하고, 더불어 방화문에 설치되는 보강대와 보호커버의 결합을 용이하게 하여 편의성을 증대하며, 화재시 고열로 형태가 변화하여 방화문의 개방이 곤란하지 않도록 보호커버의 내구성을 향상시키도록, 판금가공된 판상을 일체로 절곡시켜, 상기 실린더가 삽입 고정되도록 전방이 개방된 상태로 내부에 설치공간을 마련하고, 양측에는 관통된 설치구멍을 각각 형성시켜 내부에 설치된 상기 실린더를 작동시키는 한 쌍의 도어손잡이가 설치구멍을 통해 실린더와 결합되며, 상기 보강대의 내면에 전방이 고정설치되는 보호커버로 구성되어, 일체를 절곡하여 형성되는 보호커버를 제공하는 것이다.
