Embodiment Construction

[0021] Below in conjunction with accompanying drawing example, the present invention is described in further detail:

[0022] Such as figure 1 and figure 2 The fan blade connecting device shown includes a main body, the middle of which is a columnar positioning platform 1, and the upper end surface of the columnar positioning platform is an upper mounting plate 2, and three mounting holes 3 are opened on the upper mounting plate for columnar positioning. The lower end of the platform 1 is the lower mounting plate 4, and there are 2 mounting holes 5 on the lower mounting plate 4. There is a whole between the columnar positioning platform 1 and the two mounting plates, and the mounting plate is cut from the upper and lower ends of a columnar body. Formed, the space angle between the upper mounting plate 2 and the lower mounting plate 4 is α, and α is 42.22°, which is the installation angle of the fan blade; the upper mounting plate 2 is composed of two splints 2-1 and 2-2 The...

Abstract

The invention discloses a fan blade connecting device and a fan comprising the fan blade connecting device, and relates to the technical field of fans. The fan blade connecting device comprises a body. The middle portion of the body is a columnar locating platform, an upper installation plate with an installation hole is arranged on the upper end face of the columnar locating platform, and a lower installation plate with an installation hole is arranged on the lower end face of the columnar locating platform. A space included angle alpha is formed between the upper installation plate and the lower installation plate. The fan comprises a fan hub and fan blades, wherein the fan hub is connected with the fan blades through the fan blade connecting device. Compared with the prior art, the middle portion of the fan blade connecting device is in a columnar structure, change of an installation angle of the fan blades is convenient to achieve, and the fan is formed through fixed connection of the fan blades and the fan hub through the fan blade connecting device, so that the fan blades are convenient to install and disassemble, and the fan is low in cost and easy to popularize and apply.

Description

technical field [0001] The invention relates to a fan, in particular to a fan blade connecting device and the fan. Background technique [0002] Fans are well known in the art and their design, components and materials vary depending on the application. Typical applications for fans are ventilation and cooling, for residential or industrial use, e.g. for radiator cooling in construction machinery , On the tunnel, mining, subway for ventilation and so on. [0003] The fan includes a fluid reactive surface of at least one blade, and a fan hub to which the blade is attached. Usually for very small fans, the blades and fan hub can be made in one piece. However, industrial applications usually require larger fans whose blades and fan hub cannot be made in one piece and require an additional connecting device between the blades and the fan hub. [0004] The connection device used can determine important features related to the assembly, operation and maintenance of ...
