Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 to 7, a reverse anti-loose fan blade structure comprises a connecting structure 1 capable of being sleeved on an output shaft of a fan motor, a plurality of fan blades 2 connected to the outer wall of the connecting structure 1, and a locking cover 3 connected to the output shaft of the fan motor and used for fixing the connecting structure 1, wherein a threaded hole 32 capable of being in threaded connection with the output shaft of the fan motor is formed in the locking cover 3, the locking cover 3 is connected to one end of the connecting structure 1, the locking cover 3 is pressed against the connecting structure 1, and an anti-loose structure used for preventing the locking cover 3 from being loosened from the output shaft is arranged between the connecting structure 1 and the locking cover 3. The connecting structure 1 is pressed tightly through the locking cover 3, so that the connecting structure 1 is fixed on the output shaft of the fan motor, when the output shaft of the fan motor rotates forwards, namely clockwise, the loosening direction of the locking cover 3 is opposite to the rotating direction of the output shaft of the fan motor, the locking cover 3 can rotate more and more tightly on the output shaft of the fan motor due to the inertia effect, and the falling-off cannot occur; and when fan motor output shaft reversal, during anticlockwise rotation promptly, the direction of loosening of locking lid 3 is the same with fan motor output shaft rotation direction, and locking lid 3 may be toward the direction rotation of loosening under the inertia effect to cause not hard up, connection structure 1 with establish anti loosening structure between the locking lid 3, can avoid locking lid 3 to loosen when the fan reversal and take off, make the fan structure more stable, the security is higher.
