Closed fireproof door closer for corridor firefighting
The invention relates to the technical field of fire-fighting equipment, and discloses a closed fireproof door closer for corridor firefighting. The closed fireproof door closer for corridor firefighting comprises a wall body, a fire-fighting door and a temperature sensor, wherein the fire-fighting door is movably connected with the wall body through a rotating shaft, and a fixed box I is fixedly mounted at the top of the left side of the front surface of the fire-fighting door. Through the arrangement of a thrust spring I, a thrust spring II and a limiting rod, in the daily use process, the fire-fighting door is closed through the limiting rod in the inclined posture and under different thrust effects of the thrust spring I and the thrust spring II, and electricity consumption in the long-time use process of most electromagnetic door closers is avoided; meanwhile, in the daily use process, when the fire-fighting door is closed, thrust of the thrust spring I and the thrust spring II abutting against a sliding block I and a sliding block II is gradually reduced due to the fact that gradual release of the thrust spring I and the thrust spring II is finished; and when the thrust reaches the limit, reverse pulling can be conducted, so that the fire-fighting door can be slowly closed, violent collision between the fire-fighting door and the wall body is effectively prevented, and loss is reduced.
本发明涉及消防设备技术领域，且公开了一种楼道消防封闭式防火闭门器，包括墙体、消防门和温度传感器，所述消防门与墙体通过转轴活动连接，所述消防门的正面左侧顶部固定安装有固定箱Ⅰ。通过推力弹簧Ⅰ、推力弹簧Ⅱ和限位杆的设置，使得，在日常使用过程中，利用倾斜姿态的限位杆，以及推力弹簧Ⅰ和推力弹簧Ⅱ不同的推力作用下，完后对消防门关闭，避免大多电磁闭门器长时间使用过程中电量的消耗，同时，在日常使用过程中，在对消防门进行关闭时，由于推力弹簧Ⅰ和推力弹簧Ⅱ逐渐释放结束，其抵推滑块Ⅰ和滑块Ⅱ的推力逐渐减小，当达到极限后，可进行反拉，进而可对消防门缓慢关闭，有效预防消防门与墙体剧烈碰撞，降低损耗。
