Abstract

The invention provides an adjustable connecting device and a fan using the same, the adjustable connecting device comprises a connecting piece, a fan blade and a wheel disc, the connecting piece is arranged between the fan blade and the wheel disc, and the connecting piece can enable the relative angle between the connecting piece and the fan blade to be adjustable; and/or the relative angle between the wheel disc and the connecting piece can be adjusted; the problems that the angle of the fan blade cannot be adjusted, different performance requirements (including but not limited to static pressure, air volume and the like) of different customers cannot be met at the same time, the project development period is too long, and customer loss is caused due to the influence on the project development progress are solved; and meanwhile, the problems of too high mold opening cost and low generalization degree caused by a large amount of mold opening due to demand change are solved, the product generalization is improved, the new cost input is reduced, and extremely high practical value and cost benefit are achieved.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to an adjustable coupling device and a fan using the device. Background technique [0002] As the key component of the fan, the fan blade has a great impact on the performance of the fan. The actual use requirements of different customers are different (including but not limited to static pressure, air volume, etc.), and ordinary fan blades do not have the adjustable blade angle, making When encountering new load performance and energy efficiency ratio requirements, the assembly can no longer be used, which involves re-opening the mold and designing, which is not conducive to product versatility. Contents of the invention [0003] Therefore, the present invention aims to solve the problem that ordinary fan blades do not have blade angle adjustability, so that when meeting new load performance and energy efficiency ratio requirements, the assembly can no longer be used, wh...
