[0004] Industrial fans in the current technology usually connect the fan blades to the motor shaft, and drive the fan blades to rotate through the shaft. In order to increase the air volume, the blades of industrial fans are usually large, so they are also easy to get dusty. Disassembling and cleaning the blades of industrial fans is a rather inconvenient task. Utility Model Content

The setting of the positioning groove enables the positioning piece on the embedded block to be precisely positioned through the cooperation of the positioning block and the positioning groove, effectively preventing the blade from loosening or deviating during high-speed rotation, and improving the stability and reliability of the overall structure.

[0012] Optionally, a cross block protrudes from the positioning piece towards the blade, a cross groove is formed on the blade corresponding to the cross block, and the cross block can be embedded in the cross groove and abut against the groove wall of the cross groove.

[0013] By adopting the above technical scheme, the positioning piece and the blade of the industrial fan are precisely positioned through the cooperation of the cross block and the cross groove. This structure can effectively prevent the blade from deviating or mispositioning during installation, thereby improving the assembly precision and stability. At the same time, the close cooperation of the cross block and the cross groove can also enhance the connection strength between the blade and the cover, reduce vibration and noise during operation, and improve the overall performance.

[0014] Optionally, a bolt cylinder is further arranged on the upper cover and the lower cover, and each bolt cylinder is arranged on the two sides of the embedded groove. The bolt cylinder is provided for the bolt to extend into and connect.

[0015] By adopting the above technical scheme, the upper cover and the lower cover of the industrial fan are detachably connected through the bolt cylinder. The bolt cylinder is arranged on the two sides of the embedded groove, which makes the assembly of the upper cover and the lower cover more stable and facilitates disassembly and maintenance. The bolt cylinder provided for the bolt to extend into and connect further improves the reliability of the connection, ensures the stability of the cover structure during high-speed rotation, and prolongs the service life of the industrial fan.

[0016] Optionally, a transmission cylinder protrudes from the lower cover towards the upper cover, a clearance hole is formed on the upper cover corresponding to the transmission cylinder, and the clearance hole is provided for the transmission cylinder to be embedded.

[0017] By adopting the technical scheme, the transmission cylinder protruding from the lower cover towards the upper cover is matched with the accommodating hole formed on the upper cover, so that the accurate positioning between the upper cover and the lower cover can be realized, and the alignment accuracy of the two during assembly is ensured. This design helps to improve the assembly efficiency, and meanwhile enhances the overall structural stability of the cover body, and reduces the vibration or noise problems caused by assembly errors.

[0018] Optionally, a plurality of bolt cylinders are arranged on the lower cover, the bolt cylinders are arranged at equal intervals in the circumferential direction around the transmission cylinder, corresponding bolt cylinders are arranged on the upper cover, and the bolt cylinders are used for bolt insertion connection.

[0019] By adopting the technical scheme, the connection strength and stability between the upper cover and the lower cover are improved by the connection mode of the plurality of bolt cylinders cooperating with the bolts, the bolt cylinders are arranged at equal intervals in the circumferential direction, so that the connection stress is more uniform, the structural damage caused by local stress concentration is avoided, and the disassembly and assembly are facilitated, thereby providing convenience for subsequent maintenance and replacement.

[0020] Optionally, a plurality of reinforcing ribs are arranged in the upper cover and the lower cover.
