The invention provides a bottom sealing structure for an overhead door. The bottom of the overhead door does not need to equip with a doorsill bulged on ground, so that carrying equipment is ensured to be convenient and fast, and therefore, quick and safe pass of staff is guaranteed. One side of an overhead door body is connected to the corresponding side of a door frame through a hinge; the doorframe specifically comprises a bottom side and two sides; the edge positions, which face towards the overhead door body, of the bottom plate and the two sides of the door frame are provided with firstsealing strips; the bottom area of the overhead door body comprises two end plates and an inner cavity; the inner cavity is arranged between the front end plate and the rear end plate; a door board main body is distributed above the inner cavity of the overhead door main body; the position, which corresponds to the inner cavity, of any one end plate is fixedly provided with at least two right-angled connecting rods through pin rolls; one end of each right-angled connecting rod is connected to a horizontal pushing rod through a pin roll; a return spring axially sleeves the horizontal pushing rod, and the horizontal pushing rod is fixedly connected to one axial end of the return spring; and one end, away from the hinge, of the return spring abuts against a spring positioning sleeve.
本发明提供了一种翻门的底部密封结构，其使得翻门的底部无需再设置上凸于地面的门槛，确保搬运设备方便便捷，且保证了人员的快速安全通过。翻门本体的一侧边通过铰链连接门框的对应侧边，门框具体包括底边、两侧边，门框的底板和两侧边朝向所述翻门本体的边缘位置设置有第一密封条，所述翻门本体的底部区域包括两端板和内腔，所述内腔布置于前端板、后端板之间，所述翻门本体的内腔上方布置有门板主体，任意一块端板对应于内腔的位置上通过销轴固设有至少两个直角连杆，所述直角连杆的其中一端通过销轴连接水平推杆，水平推杆的轴向套装有复位弹簧、并固接所述复位弹簧的轴向一端，所述复位弹簧的远离所述铰链的一端顶装于弹簧定位套筒。
