[0002] Industrial fans are a common industrial machine widely used in industrial plants, logistics warehouses, waiting rooms, exhibition halls, gymnasiums, supermarkets and other tall spaces as space ventilation and personnel cooling. Industrial fans can push a large amount of airflow to the ground, forming a certain height of airflow layer horizontal movement on the ground, thereby promoting overall air circulation. The advantage is that the ground is covered in all directions and the air is circulated in three dimensions. As we all know, when the electric fan is working, the blades are charged with static electricity due to the friction between the blades and the air.

[0032] When the utility model is used to disassemble the mesh cover 101, the pulling block 109 is pulled to drive the fixing rod 110 to move out of the fixing block 111, and then the mesh cover 101 is rotated counterclockwise through the handle 113 to move the T-shaped block 104 out of the T-shaped slot 106. At this time, the mesh cover 101 can be removed from the front end surface of the fan outer ring 103. When it is necessary to install it, the mesh cover 101 is installed on the front end surface of the fan outer ring 103, and the T-shaped block 104 is inserted into the The mesh cover 101 is rotated clockwise in the T-slot 106 at the same time, so that the T-block 104 is completely against the T-slot 106, and then the fixing rod 110 is inserted into the fixing block 111. Through the action of the tension spring 108, the fixing rod 110 can be prevented from accidentally falling out of the fixing block 111. In this way, the technical problem that the mesh cover 101 and the fan outer ring 103 still need to be fixed by bolts, and the disassembly and assembly of the bolts is relatively troublesome is solved, thereby achieving the effect of quickly disassembling and assembling the mesh cover 101.
