Two-way opening and closing airtight door for civil air defense engineering
The invention discloses a two-way opening and closing civil air defense engineering air-tight door in the technical field of civil air defense engineering, which comprises a door frame and an air-tight door, a plurality of rotating shafts are fixedly arranged in the door frame, the upper ends of the rotating shafts are rotatably connected with first rotating pieces, and the outer surfaces of the first rotating pieces are fixedly connected with first connecting rods. A first connecting ring is fixedly connected to the end, away from the first rotating piece, of the first connecting rod, a firstconnecting shaft is rotatably sleeved with the first connecting ring, a third connecting piece is rotatably sleeved with the lower end of the first connecting shaft, and a first fixing shaft is rotatably sleeved with the end, away from the first connecting shaft, of the third connecting piece. The lower end of the first fixing shaft is fixedly connected to the upper surface of the air-tight door,a plurality of movable telescopic rods are fixedly installed in the air-tight door, compression springs are movably connected to the large portions of the movable telescopic rods in a sleeved mode, and the two ends of each compression spring are connected into the air-tight door. Meanwhile, leakproofness is improved, and harmful gas is prevented from entering civil air defense engineering.
本发明公开了人防工程技术领域的一种双向开合人防工程用密闭门，包括门框和密闭门，门框的内固定安装有多个转轴，转轴的上端转动连接有第一转动件，第一转动件的外表面固定连接有第一连接杆，第一连接杆远离第一转动件的一端固定连接有第一连接环，第一连接环内转动套接有第一连接轴，第一连接轴的下端转动套接有第三连接件，第三连接件远离第一连接轴的一端转动套接有第一固定轴，第一固定轴的下端固定连接在密闭门的上表面，密闭门内固定安装有多个活动伸缩杆，活动伸缩杆大的活动套接有压缩弹簧，压缩弹簧两端连接在密闭门内，此装置增加人防工程密闭门的承压能力，同时增加密闭性防止有害气体进入人防工程。
