Abstract

The invention provides a fan blade. The fan blade comprises a wheel hub and a plurality of blades which uniformly surround the hub; the blades are fixedly connected or connected to the hub through bolts and nuts; the diameter of the hub is 8 to 14 cm; the length of the blades is from 7 to 12 cm; the hub is provided with a wire passing plate; the wire passing plate is provided with a through hole; the diameter of the through hole is from 1.2 to 1.6 cm; an elastic rubber ring is arranged inside the through hole; a wire inlet hole is formed in the elastic rubber ring; the diameter of the wire inlet hole is from 0.5 to 0.8 cm. According to the fan blade, the elastic rubber ring is arranged at the through hole of the wire passing plate, wires enters into the hub from the wire inlet hole of the elastic rubber ring, the wires are fixed at the wire inlet hole to some extent and wire movement is slowed down due to the fact that the elastic rubber ring has certain elasticity, certain wire abrasion caused by movement is reduced due to the elastic rubber ring, the connected wires is protected, normal utilization of the fan blade is guaranteed, the service life is prolonged.

Description

technical field [0001] The invention relates to a fan blade. Background technique [0002] During the use of the fan, the fan blades are fixed on the hub for rotation, and the power of the fan blades is provided by the motor in the hub connected to the power supply through wires, but the wires often move at the hub to cause certain wear or cause the wires and the motor to disconnect. The connection is broken, which affects the normal use. How to solve the above problems is a problem that should be solved in the design, production and use of the electric fan. Contents of the invention [0003] The purpose of the present invention is to provide a fan blade to solve the problem that the power of the fan blade is provided by the motor in the hub connected to the power supply through wires, but the wires often move at the hub to cause certain wear or cause the connection between the wire and the motor to break, and Problems affecting normal use. [0004] Technical solu...
