The invention discloses a rotary opening and closing mechanism and an opening and closing device for a civil air defense door leaf. The rotary opening and closing mechanism comprises a base and a civil air defense door leaf door body arranged above the base, a first built-in door plate and a second built-in door plate are rotationally arranged in the interior of the civil air defense door leaf door body, handles are fixedly arranged on the surface of the first built-in door plate and the surface of the second built-in door plate correspondingly, a buckle assembly is arranged between the first built-in door plate and the second built-in door plate, and rotation contraction devices used for automatically opening the first built-in door plate and the second built-in door plate are arranged between the surface of the first built-in door plate and the surface of the civil air defense door leaf body and between the surface of the second built-in door plate and the surface of the civil air defense door leaf body. According to the rotary opening and closing mechanism and the opening and closing device for the civil air defense door leaf, through the first built-in door plate and the second built-in door plate, multiple guarantees of functional safety of the civil air defense door leaf can be improved, the first built-in door plate and the second built-in door plate can automatically reset under the action of the rotation contraction assemblies, the civil air defense door leaf body can be opened and closed by lifting a switch; the civil defense door leaf body can further be opened and closed by rotating the switch, and after one opening mode is damaged, continuous use can be carried out in an alternative opening mode.
本发明公开了一种转动开合机构及人防门扇用开闭装置，包括底座、以及设置于所述底座上方的人防门扇门体，所述人防门扇门体内部转动设置有第一内置门板以及第二内置门板，所述第一内置门板和所述第二内置门板表面均固定有把手，所述第一内置门板与所述第二内置门板之间设置有卡扣组件，所述第一内置门板表面和所述第二内置门板表面与所述人防门扇门体。本发明通过第一内置门板和第二内置门板，可以提高人防门扇功能性安全的多重保障，第一内置门板与第二内置门板受到转动收缩组件作用可以自动复位，并且人防门扇门体可以进行升降开关闭合，而且人防门扇门体本身也可以转动开关闭合，其中一种开启方式损坏后，有备选开启方式可以继续使用。
