Fireproof door convenient for ventilation
The invention discloses a fireproof door convenient for ventilation. According to the fireproof door convenient for ventilation, a first cavity is formed in an upper door panel, a rotating member is disposed within the first cavity, a shaft sleeve is disposed on the outer side of the rotating shaft and is connected to the bottom of a third cavity by a torsion spring, a first protruding block is disposed on the inner side of the rotating shaft, and a second protruding block is disposed on the inner side of the shaft sleeve. When the rotating speed is too high and a door panel is closed, the first protruding block releases limitations of the second protruding block, a first magnetic member does not move, that is, the first magnetic member and a second magnetic member repel each other to rebound the door panel; at this time, the first protruding block returns to the lower portion of the second protruding block; when a door is closed slowly, the first protruding block will abut against thesecond protruding block to slide the first magnetic member into a groove; and at this time, the door can be normally closed, the door panel is prevented from being accidentally closed when ventilation is needed, and therefore a room is kept in a ventilation state.
本发明公开一种便于通风的防火门，一种便于通风的防火门通过在上门板上设置第一腔体，将转动件设置在第一腔体内，在转动轴外侧设置轴套，所述轴套通过扭簧连接在第腔体底部，在转动轴内侧设置第一凸块，在所述轴套内侧设置第二凸块，在转动速度过快时，所述门板在关闭时，所述第一凸块突破第二凸块的限位，所述第一磁性件不会移动，即所述第一磁性件和第二磁性件相斥将门板弹回，此时的第一凸块恢复到第二凸块下方，在慢速关门时，所述第一凸块将抵住第二凸块将第一磁性件滑动到所述凹槽中，此时可以正常关上门，实现在需要通风的时候防止门板会意外关闭，实现保持房间在一直通风的状态。
