Description

Technical Field

[0001] The utility model relates to the technical field of fan blade fixing and installation, in particular to a fan blade fixing and installation mechanism. Background Art

[0002] An electric fan is a common household appliance used to generate airflow for cooling, ventilation, or odor removal. It primarily consists of a motor, blades, a housing, and a speed control device. Depending on the application and function, electric fans can be categorized into various types, including desktop fans, floor-standing fans, wall-mounted fans, ceiling fans, and exhaust fans. Electric fans work by rotating blades driven by an electric motor, thereby promoting air flow. As the blades spin, they exert force on the surrounding air, moving it in a specific direction, creating an airflow that helps people feel cool. Especially during the hot summer months, electric fans can effectively lower the room temperature or improve air circulation, providing a more comfortable environment for users.

[0003] In the prior art, fan blades are generally radially distributed on the periphery of the mounting base and fixed to the mounting base by bolts. However, when the electric fan rotates at high speed for a long time, the bolts fixed to the mounting base may not be able to withstand the mechanical stress and vibration generated by the long-term high-speed rotation, causing the fan blades to loosen or fall off, affecting the stability and safety of the fan. At the same time, the lack of corresponding positioning structure when installing the fan blades may cause the fan blades to easily deviate during installation, affecting the balance and operating efficiency of the fan. For this reason, a fixed installation mechanism for fan blades is proposed to solve the above-mentioned problems. Utility Model Content
