Abstract

The invention belongs to the technical field of fan blades, particularly relates to a multi-angle precise adjusting mechanism for fan blades, and solves the technical problem of unreasonable design in the prior art. The multi-angle precise adjusting mechanism comprises a connector disposed at the roots of the fan blades. An adjusting positioning sleeve sleeves the connector and is inserted into a connecting hole in the lateral part of a mounting plate. A first angle adjusting positioning structure is disposed between the outer side of the adjusting positioning sleeve and the connecting hole. A second angle adjusting positioning structure is disposed between the inner side of the adjusting positioning sleeve and the connector. Compared with the prior art, the multi-angle precise adjusting mechanism has the advantages that the multi-angle precise adjusting mechanism is reasonable in design, simple and compact in structure, wide in angle adjusting range, high in precision, firm in structure, low in noise, high in freedom degree, capable of fast adjusting fan blades at various angles so as to achieve wind strength required by people, wide in application range, long in service life, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of wind blades, and in particular relates to a multi-angle precision adjustment mechanism for wind blades. Background technique [0002] At present, the blades of fans are mostly made of thermoplastics and metals. Using thermoplastic blades is easy to deform, which affects the use effect. Using metal materials, the blades are heavy, difficult to process and inconvenient to shape. Due to the smooth surface of the wind blade at present, the noise is large, the wind force is not concentrated enough, the angle of the blade is not adjustable, and its inclination angle is fixed, and the inclination angle of the blade cannot be adjusted according to the wind force required by the site. Purchasing products of different specifications to meet the needs of different wind forces will increase the cost of the enterprise, and if temporary adjustments are required, cumbersome disassembly operations will also affect the pr...
