Fan blades for floor fan

Abstract

The invention relates to a fan blade for a floor fan, which includes a front net cover, a fixed chassis, a motor, a rear net cover, a fan blade fixing seat, a fan blade and a fan cable nut, and both sides of the inner bottom of the fixed chassis are installed with A counterweight, and a base column is vertically installed at the middle position of the top of the fixed chassis, a fastening snap ring is installed on the top of the base column, and a telescopic support rod is vertically installed inside the base column to pass through the fastening snap ring . The present invention installs the fan blade fixing seat, the fan blade cable nut, the threaded screw rod, the fixing nut and the second fixing screw hole. When in use, the fixing nut is screwed to loosen the threaded screw rod, and then the fan blade fixing seat is turned to adjust the angle. Tighten the fixing nut so that the fan blade can adjust the angle at any time, which is convenient and quick. At the same time, the device is equipped with a counterweight to enhance the stability of the device and prevent the phenomenon of tipping due to an unstable center of gravity.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan blade for a floor fan. Background technique [0002] An electric fan is referred to as an electric fan, also known as a fan or a fan. It is an electrical appliance that uses a motor to drive the fan blades to rotate to accelerate the circulation of air. It is mainly used for cooling and relieving heat and circulating air. It is widely used in homes, offices, and shops. In places such as hospitals, hotels, etc., the fan blade is the most important part of the fan. It includes the base that is set on the motor shaft to form a linkage and the blades that are fixed around the outer periphery of the base. The inclination angle between the blade and the base and the relative relationship between the blades Factors such as the position and the bending angle of the blade itself directly affect the size of the airflow generated by the fan and affect the air circulation effect. Then, th...

It includes the base that is set on the motor shaft to form a linkage and the blades that are fixed around the outer periphery of the base. The inclination angle between the blade and the base and the relative relationship between the blades The position, the bending angle of the blade itself and other factors directly affect the size of the airflow generated by the fan and affect the air circulation effect. Then, the requirements for the length of the blade and the angle of inclination between the blade and the base are different under different conditions, but the traditional fan blade cannot Adjustment
