[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 4 As shown, a fan blade anti-falling structure includes a rotating connecting disk 11 that is rotatably connected to the output shaft of the ceiling fan motor 1 through a bearing in its specific structural design. A plurality of connecting rods 12 are connected to the four sides of the rotating connecting disk 11 by bolts, and the plurality of connecting rods 12 are respectively used to connect the ceiling fan blades 2 by bolts; two adjacent ceiling fan blades 2 are connected by a safety connecting ring 21, and a blade tail wing 22 is connected to the end of each ceiling fan blade 2 away from the rotating connecting disk 11 by bolts. The purpose of such design is that all the ceiling fan blades 2 are connected by the safety connection ring 21, and all the ceiling fan blades 2 form a whole. If the root of any ceiling fan blade 2 becomes loose or broken, the safety connection ring will pull the ceiling fan blade 2 to prevent it from falling and injuring people; and, by providing a blade tail wing 22 on each ceiling fan blade 2, the main structure of the blade tail wing 22 is an inclined and upwardly tilted wing plate. The higher the speed of the ceiling fan 1, the stronger the downward reaction force generated by the ceiling fan blade 2. Therefore, the greater the upward tilt amplitude of the ceiling fan 1, the greater the upward and downward swing amplitude of the ambient "windflow" on the fan, and the blade tail wing 22 can reduce the blade swing amplitude and the upward tilt amplitude of the ceiling fan 2, and finally can achieve the reduction of the "pressure and resistance" generated by the rotation of the ceiling fan blade 2, thereby reducing the loosening or breaking of the root of the ceiling fan blade 2. The combination of the two can further reduce the possibility of the ceiling fan blade 2 falling. Moreover, the rotary connecting disk 11 is provided to avoid direct connection between the ceiling fan blades 2 and the ceiling fan motor 1, thereby reducing the possibility of the ceiling fan blades 2 and the ceiling fan motor 1 becoming loose at the "direct connection point" due to the rotation of the ceiling fan motor 1 during use, thereby reducing the possibility of falling; at the same time, each ceiling fan blade 2 is connected to the rotary connecting disk 11 through the connecting rod 12, thereby facilitating the replacement and connection of the ceiling fan blades 2, and reducing the probability of the ceiling fan blades falling by strengthening the connection between the ceiling fan blades 2 and the connecting rod 12.

[0021] Furthermore, in the embodiment, the top shell of the ceiling fan motor is connected to an anti-falling plate 3 by bolts, and a passage opening is provided in the middle of the anti-falling plate 3, and a connecting shaft 12 is passed through the passage opening. One end of the connecting shaft 12 passes through the passage opening and is connected to the top shell of the ceiling fan motor 1, and the other end of the connecting shaft 12 is connected to the vertical hanging beam 4 by bolts, and the other end of the vertical hanging beam 4 is used to be connected to the supporting steel beam 5 of the roof; connecting clips 13 are respectively provided on both sides of the connecting shaft 12, and the connecting clips 13 are used to limit the connection between the connecting shaft 12 and the anti-falling plate 3. At the same time, the end of the connecting shaft 12 close to the vertical hanging beam 4 is passed through the vertical hanging beam 4, and the upper parts of the two connecting clips 13 connect the connecting shaft 12 to the vertical hanging beam 4 by bolts; the lower parts of the two connecting clips 13 are connected to the connecting shaft 12 by bolts; the bottom ends of the two connecting clips 13 are connected to an inverted hook, and the inverted hook is used to limit the inverted hook on the bottom end surface of the anti-falling plate 4. At the same time, connecting ears are connected to both sides of the connecting clip 13, and the connecting ears are used to connect the steel wire ropes 14 that serve as limit support for the connecting shaft. During use, if the "connection" between the connecting clip 13, the connecting shaft 12 and the vertical hanging beam 4 becomes loose and broken, the bottom end of the connecting clip 13 is connected with an inverted hook, which is used to limit the inverted hook on the bottom end surface of the anti-falling plate 3, and the ceiling fan motor 1 is limitedly connected to the anti-falling plate 3. The "four" steel wire ropes 14 support and limit the ceiling fan motor 1, further ensuring stability and reducing the possibility of the ceiling fan motor 1 and the ceiling fan blades 2 falling. Furthermore, in this embodiment, a support angle steel 41 is provided at the top of the vertical suspension beam 4. The bottom end of the support angle steel 41 is bolted to the vertical suspension beam 4. Limiting clamps are provided on both sides of the top of the support angle steel 41. The limiting clamps are used to clamp the support steel beam 5 and the support angle steel with bolts, further ensuring that the vertical suspension beam 4 stably supports the ceiling fan structure below. From the perspective of the overall design structure, this anti-fall structure is used to strengthen the limit connection between the ceiling fan blades and the ceiling fan motor and the ceiling fan bracket supporting the entire ceiling fan, thereby reducing the possibility of accidental falling of the ceiling fan blades.

However, the present invention is not limited to the specific details of the embodiments in the above description. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
