The invention provides a switching-on-and-off transmission mechanism of a personnel gate sealing door. The mechanism comprises a lower part supporting bearing assembly, a sealing door assembly, an upper part supporting member, a large-torque high-speed-ratio reducer, a bidirectional backstop, a steering device and a universal coupling device. By means of the transmission mechanism, functions of the switching on and off of the sealing door, the fixing of the sealing door and the switching on and off of large torque can be completed, and the transmission mechanism is suitable for the working condition in which the sealing door is heavy and subjected to impacting and swinging. 本发明提供种人员闸门密封门启闭传动机构，其包括：下部支撑轴承组件、密封门组件、上部支撑、大扭矩大速比减速机、双向逆止器、转向器和万向联轴器。本发明提供的人员闸门密封门启闭传动机构，可以完成密封门的启闭、密封门的固定、大扭矩启闭的功能。适用于密封门质量大、受到冲击、摇摆的工况。
