Steel structure civil defense door suitable for underground protection engineering
The invention relates to the technical field of civil air defense doors, and discloses a steel structure civil defense door suitable for underground protection engineering. The steel structure civil defense door comprises a protection door, a wall body, switch mechanisms and antifriction mechanisms, the protection door is movably mounted on the wall body, a rotating core is fixedly mounted on theleft side of the protection door, a hand wheel is movably mounted on the front surface of the protection door, the switch mechanisms are fixedly mounted on the front face of the wall body, the antifriction mechanisms are fixedly mounted on the opposite sides of the two switch mechanisms, and a lapping ring is fixedly mounted on the front face of the wall body. A civil defense door is usually madeto be quite heavy, so that when the civil defense door is opened and closed, due to the weight of the door, the door only has one hinge as a supporting point during rotation, large pressure can be applied to the hinge, large friction force can be generated, rotation is more labor-consuming, according to the steel structure civil defense door, the friction force between the hinge and the civil defense door can be reduced when the civil defense door is opened, and the civil defense door can be opened in a more labor-saving mode.
本发明涉及人防门技术领域，且公开了一种适用于地下防护工程的钢结构人防门，包括防护门、墙体、开关机构和减摩机构，所述防护门活动安装在墙体上，所述防护门左侧固定安装有转芯，所述防护门正面活动安装有手轮，所述开关机构固定安装在墙体的正面，所述减摩机构固定安装在两个开关结构的相向一侧，所述墙体正面固定安装有搭环，由于人防门的质量通常都会做的相当重，在开关时，由于门的重量，在转动时门只有合页这一个支撑点，会给合页相当大的压力，从而会产生相当大的摩擦力，使转动更加费劲，该设备可以在开启人防门时减少合页与人防门之间的摩擦力，使人防门的开启更加省力。
