Description

Technical Field

[0001] The present application relates to the technical field of ceiling fans, and in particular to an industrial ceiling fan. Background Art

[0002] As a heat dissipation device widely used in daily life and industrial production, ceiling fans are deeply loved by people due to their simple mechanical principles and efficient heat dissipation effects. Especially in large-scale industrial production processes, in large factories, due to their large space, the cooling effect of air conditioning is greatly reduced, and the installation of large ceiling fans can achieve a good heat dissipation effect. Therefore, ceiling fans are widely used as heat dissipation tools in the production process.

[0003] In the prior art, the main unit of the ceiling fan is directly connected to the turntable and fan blades to be driven through the transmission shaft of the motor, so as to realize a working mode in which the motor drives the fan blades to rotate to generate wind. However, in the prior art, the connection between the rotating shaft and the turntable and the fan blades is relatively simple, and the weight of the turntable and the fan blades is completely borne by the rotating shaft. There is a lack of necessary protective devices. Once the rotating shaft is damaged, it is very likely to break under the action of the torsional force of the motor, which will cause great harm. Therefore, there is room for improvement. Summary of the invention

[0006] It is further configured that the shell is provided with an extension block corresponding to the extension direction of the rotating shaft, and the turntable is provided with an installation cavity corresponding to the extension block, and the extension block is arranged in the installation cavity. Through this configuration, a certain guiding effect is played on the connection between the main machine and the turntable, and a position is reserved for the installation of a subsequent anti-detachment device, making the overall structure tighter.

[0007] It is further configured that the first limiting portion includes a first limiting plate, the first limiting plate is arranged at the end of the extension block, the second limiting portion includes a second limiting plate, the second limiting plate is arranged as a central opening, and the first limiting plate cover is arranged at the outer end of the mounting cavity. Through this configuration, the first limiting plate and the second limiting plate are respectively firmly connected to the extension block and the turntable, and the overall structure is stable.

[0008] It is further configured that the inner diameter of the second limiting plate is smaller than the mounting cavity, the outer diameter of the first limiting plate is larger than the inner diameter of the second limiting plate, and the outer diameter of the first limiting plate is smaller than the inner diameter of the mounting cavity, and does not rub against the inner wall of the mounting cavity. Through this configuration, the first limiting plate and the second limiting plate are limitedly matched along the axial direction of the rotating shaft, thereby playing a basic anti-slip function.

[0009] It is further configured that the installation cavity is opened into a pentagon corresponding to the number of fan blades, and the first limiting plate and the second limiting plate are both configured as pentagons corresponding to the installation cavity. Through this configuration, circumferential limiting makes the transmission between the rotating shaft and the turntable more stable and efficient.

[0010] It is further arranged that the first limiting plate is detachably connected to the extension block by means of a first screw. This arrangement facilitates installation and ensures stable installation.

[0011] It is further arranged that the second limiting plate is detachably connected to the turntable by means of a second screw. Through this arrangement, the installation is convenient and stable.

[0012] It is further provided that a heat dissipation hole is provided on the shell corresponding to the position of the motor.

[0013] In summary, the industrial ceiling fan is provided with an anti-dropping device between the main unit and the turntable in addition to the rotating shaft, so that the turntable can be prevented from falling off due to the breakage of the rotating shaft without affecting the rotation of the turntable driven by the rotating shaft, thereby achieving a better safety precaution effect.
