Abstract

The utility model provides a fan blade fast-assembling structure, wherein in the process of assembling, the inserting end of a fan blade passes through an inserting opening and is inserted into a bearing box, in the process, the inserting end of the fan blade is abutted with a clamping block and drives a rotating sleeve to rotate around a rotating column through the clamping block, and in the rotating process, the rotating sleeve extrudes the movable end of an S-shaped spring piece through a driving piece. After the inserting end of the fan blade is completely inserted into the receiving box, the S-shaped spring piece is elastically deformed, the driving piece drives the rotating sleeve to rotate, and the driving clamping block is inserted into the limiting bayonet and clamped with the inserting end of the fan blade in the rotating process. The screw rod passes through the threaded perforation and the penetrating hole, and the second nut is sleeved on the screw rod and is in threaded connection with the screw rod, so that the inserting end of the fan blade is connected with the bearing box. The fan blade fast-assembling structure is convenient for installing and detaching the fan blade, so that the installing and detaching efficiency of the ceiling fan is improved.
