Description

Fan blade mounting structure of ceiling fan Technical Field The utility model relates to the technical field of ceiling fans, in particular to a fan blade mounting structure of a ceiling fan. Background The blades of the ordinary ceiling fan can be firstly installed on the motor, and then the motor shaft is fixed on the top wall of the room through the top wall of the room and the like, because the motor shaft of the ordinary ceiling fan is longer, the height of the outer cover is smaller, and the outer cover for surrounding the hanging frame is allowed to move downwards along the motor shaft for a larger distance without interfering the hanging frame to be installed on the top wall of the room. The ceiling type ceiling fan and the motor shaft are short in length, the outer cover is large in height, the outer cover can only move a small distance along the motor shaft and can interfere the hanging frame to be mounted on the top wall of a room, therefore, the outer cover and the motor shaft are required to be fixed first, the top end of the motor shaft is required to be fixed on the top wall of the room through the hanging frame, and the blades are required to be mounted on the rotor on the premise that the motor shaft is required to be hung on the top wall of the room. The blade of traditional ordinary ceiling fan is fixed on the rotor through the screw, and after moving the blade and realizing that the through hole on the blade aligns with the screw hole on the rotor, need to rotate the screwdriver through the screwdriver and pass the blade screw in rotor through the screwdriver while keeping the state of holding up the blade, adjustment of blade position, installation of blade are all more troublesome.
