Protective air-tight door for civil air defense engineering
The invention relates to the technical field of civil air defense equipment, in particular to a protective air-tight door for civil air defense engineering. The protective air-tight door comprises a door frame and two movable doors rotationally connected with the interior of the door frame, each movable door comprises a door plate rotationally connected with the door frame, a control seat is fixed on the inner surface of each door plate, a first rotating pipe is rotationally connected with the interior of each control seat, the outer wall, located in each control seat, of each first rotating pipe is fixedly sleeved with a first bevel gear, a rectangular groove is formed in the position, close to each first bevel gear, of the outer surface of each control seat, and first transmission screws extending to the two sides of each control seat are connected to the interior of each first rotating pipe in a screwed mode. According to the protective air-tight door, adjusting rudders are used for driving supporting assisting wheels to conduct rolling assisting on the ground, so that an operator can conveniently rotate the door plates which are difficult to rotate, the protective air-tight door which is not used for a long time can be conveniently opened and closed, and normal use of the protective air-tight door is guaranteed.
本发明涉及人防设备技术领域，具体涉及一种人防工程用防护密闭门，包括门框及其内部转动连接的两个活动门，所述活动门包括与门框转动连接的门板，所述门板的内表面固定有控制座，所述控制座的内部转动连接有一号转管，所述一号转管位于控制座内的外壁套接固定有一号锥齿轮，所述控制座的外表面紧邻一号锥齿轮所在位置处开设有矩形槽，所述一号转管的内部旋合连接有延伸至控制座两侧的一号传动螺杆。本发明中，通过利用调节舵驱动支撑助轮与地面进行滚动助力，从而方便操作人员对难以转动的门板进行旋转，从而方便对长期未使用的防护密闭门进行开启和关闭，保证防护密闭门的正常使用。
