Fireproof door capable of preventing accidental closing
The invention discloses a fireproof door capable of preventing accidental closing. According to the fireproof door capable of preventing accidental closing, a first cavity is formed in the upper doorframe, a rotating part is arranged in the first cavity, a winding reel is arranged above the rotating shaft, the winding reel is connected with a first magnetic part through a first pull rope, and when the rotating speed is too high, when a door plate is closed, the second magnetic part does not slide together with the first magnetic part, a third magnetic part is arranged on the outer side of a groove, a fourth magnetic part and the third magnetic part which are arranged on the door plate repel each other to rebound the door plate, and when the door is closed at a low speed, the first magnetic part and the second magnetic part move together to move the third magnetic part into the groove. At the moment, the door can be normally closed, the door plate is prevented from being accidentally closed when ventilation is needed, and ventilation is achieved all the time.
本发明公开防止意外关闭的防火门，防止意外关闭的防火门通过在上门框中设置第一腔体，将转动件设置在第一腔体内，在转动轴上方设置绕线筒，所述绕线筒通过第一拉绳和第一磁性件连接，在转动速度过快时，所述门板在关闭时，所述第二磁性件不和第一磁性件一起滑动，所述第三磁性件在凹槽外侧，门板上设置的第四磁性件和第三磁性件相斥将门板弹回，在慢速关门时，所述第一磁性件和第二磁性件一同移动，将所述第三磁性件向凹槽内移动，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，实现一直通风。
