Description

Technical Field

[0001] The utility model relates to the technical field of ceiling fan equipment, and particularly relates to a ceiling fan with an anti-falling function. Background Art

[0002] In the existing technical field of ceiling fans, although ceiling fans are loved by users for their unique air circulation effect and decoration, safety issues have always been the focus of user attention. Especially in some extreme cases, such as the fracture of the main shaft, it may cause the fan blades to fall, bringing serious safety hazards to users. Therefore, developing an anti-falling ceiling fan that can avoid the phenomenon of fan blade falling due to the fracture of the main shaft during use has important practical significance and application value.

[0003] In the traditional ceiling fan design, when the main shaft breaks, it is often unable to effectively prevent the fan blades from falling. This is mainly because in the traditional ceiling fan design, the fan blades and the main shaft are usually directly connected. Once the main shaft breaks, the fan blades will lose support and fall. In addition, although some traditional ceiling fans adopt protective measures such as safety nets, when the main shaft breaks, these measures often cannot completely prevent the fan blades from falling, and there are still safety hazards.

[0004] A Chinese patent (application number: 2023220284373) for an anti-falling structure of a ceiling fan includes a mounting rod and an outer rotor motor. The outer rotor motor includes a stator and a rotor. The mounting rod passes through the stator from bottom to top and is directly or indirectly fixed to the ceiling. The mounting rod includes a first connecting portion, a motor mounting portion, and a second connecting portion arranged in sequence from bottom to top; a through hole is also provided in the middle of the mounting rod, and the through hole penetrates from the top of the second connecting portion to the bottom of the first connecting portion; it also includes an anti-falling rope, one end of the anti-falling rope is provided with a connecting cover, and the connecting cover is installed and fixed at the bottom of the first connecting portion; the other end of the anti-falling rope passes through the through hole and is directly installed and fixed to the ceiling. By fixing one end of the anti-falling rope to the bottom of the ceiling fan and directly fixing the other end to the ceiling, the utility model can achieve the anti-falling effect when the ceiling fan breaks at any part, improving the reliability of the anti-falling structure and the safety of the ceiling fan.

[0005] The above patent provides a structure for preventing the fan blades from falling when the main shaft of the ceiling fan breaks. However, it mainly realizes the anti-falling function through the anti-falling rope. However, the installation method of the anti-falling rope is relatively complex, and its safety performance and stability are also poor, and it cannot achieve a good anti-falling effect, and there is still a risk of falling. Summary of the Utility Model

[0006] In order to solve the above problems, the embodiment of the utility model provides a ceiling fan that can realize its anti-falling function by restricting the transmission shaft. The overall structure is simpler and more convenient for installation, and it will not affect the stability of the ceiling fan.

[0007] In order to achieve the above object, the embodiment of the utility model specifically adopts the following technical solutions: An anti-falling ceiling fan, comprising a hoisting part, a driving part and a blowing part arranged in sequence from top to bottom.

[0008] The driving part includes a motor installed on the positioning plate. A housing is arranged outside the motor, and a bearing seat is arranged at the lower part of the housing;

[0009] The blowing part includes a turntable located below the housing. A transmission component connected to the bearing seat is arranged at the upper part of the turntable, and fan blades are arranged around the turntable.

[0010] As a further improvement of the above technical solution:

[0011] A support plate for installing the bearing seat is arranged at the bottom of the housing, and an installation hole corresponding to the position of the bearing seat is arranged in the middle of the support plate.

[0012] The transmission component includes an anti-falling bracket arranged below the support plate. A through hole is arranged in the middle of the anti-falling bracket, and a transmission sleeve is arranged in the through hole.

[0013] A clamping ring plate located inside the anti-falling bracket is arranged at the upper part of the transmission sleeve, and the lower part is connected to the turntable. The diameter of the clamping ring plate is larger than the diameter of the through hole.

[0014] The anti-falling bracket is U-shaped, and extension plates connected to the support plate are arranged at both ends of the anti-falling bracket.

[0015] A plug-in plate for connecting the fan blades is arranged on the side wall of the turntable, and a plug-in groove for cooperating with the plug-in plate is arranged at the end of the fan blade.

[0016] Connecting rib plates are arranged on the lower surface of the fan blade, and bolts for connecting to the plug-in plate are arranged at both ends of the connecting rib plate.

[0017] The number and positions of the plug-in plates and the fan blades correspond to each other, and are multiple and evenly distributed along the circumferential direction of the turntable.

[0018] An annular pressing plate is arranged above the multiple fan blades, and the annular pressing plate is connected to the plug-in plate by bolts.
