Civil air defense protective air-tight door easy to operate
A civil defense protective air-tight door easy to operate comprises a door body and a door frame, one side of the door body is hinged to the door frame, a push-pull handle is further arranged on the door body, supporting legs distributed in the door body in a sliding mode in the vertical direction are arranged in the door body, a jacking spring used for jacking the supporting legs upwards is arranged in the door body, the push-pull handle is arranged on the door body in a sliding mode in the transverse direction, and a pressing rod is arranged on the push-pull handle. The pressing rod abuts against the upper end of the supporting leg when the door body is in an open state, so that the lower end of the supporting leg penetrates out of a penetrating hole formed in the bottom of the door body and is supported on the ground, the pressing rod can transversely move along with the push-pull handle in the closing process of the door body so that the supporting leg can be staggered, the supporting leg can move upwards under the thrust action of the jacking spring, and the lower end of the supporting leg can be submerged into the penetrating hole. On the basis that the weight borne by the hinge can be shared to protect the hinge, the convenience degree of opening and closing of the civil air defense protective air-tight door is further improved.
一种易操作的人防防护密闭门，包括门体和门框，门体的一侧与门框铰接，门体上还设有推拉把手，门体内设有沿竖向滑动分布的支腿，在门体中设有用于将支腿向上顶起的顶簧，推拉把手沿横向滑动设置在门体上，在推拉把手上设有压杆，压杆在门体开启状态下顶触于支腿上端，以使支腿下端由开设在门体底部的穿孔中穿出并支撑于地面，压杆在门体关闭过程中能够随推拉把手横移以错开支腿，使支腿在顶簧的推力作用下上移，并使支腿的下端没入穿孔中。本发明旨在能够分担铰链所受重量以保护铰链的基础上，进一步提高人防防护密闭门开闭的便利程度。
