Problems solved by technology

[0002] The fan blades of industrial fans are generally long and heavy, and their installation position is often located on the top of the center of the factory building. During the operation of the fan, due to the vibration and airflow fluctuation caused by the rotation, the fan blades are easily detached from the fan frame. , or even broken, will cause personal injury to the staff working under the fan
In order to reduce the weight of the fan blades, the fan blades are made hollow, but the problem of how to securely install the hollow fan blades on the fan frame has always troubled people.

Embodiment Construction

[0021] Such as Figure 1 to Figure 7 The fan blade shown has a blade body 10, the blade body 10 is elongated, and the blade body 10 has a cavity 12 inside, and the cavity 12 extends along the length direction of the blade body 10 and runs through it. Two ends of the fan blade body 10 .

[0022] The cavity 12 is provided with several pairs of ribs (14, 15) on the upper and lower sides of the head of the fan blade body 10, each of the ribs (14, 15) is provided with a gap 14-1, and each of the ribs (14, 15) is provided with a gap 14-1. The notches face each other to form a clamping space 11 for clamping a plate-shaped object. The blade body 10 is provided with a plurality of installation through holes 10 - 1 on the upper and lower walls of the clamping space 11 . In fact, each pair of convex ribs (14, 15) can be butted to form a rib to increase the strength of the fan blade, and the gap 14-1 can be reinforced by a platform extending outward from the side of the rib and Rib side...

Abstract

The invention relates to a fan blade which is provided with a fan blade body, wherein the fan blade body is strip-shaped and is hollow inside, the cavity is extended in the length direction of the fan blade body and penetrates through two ends of the fan blade body. The fan blade is characterized in that a plurality of pairs of ribs are arranged on the upper and lower sides of the head part of the fan blade body in the cavity and are provided with notches, all notches are opposite to form a clamping space capable of clamping plate-like bodies, and the fan blade body is provided with a plurality of installation through holes on the upper and lower wall surfaces of the position of the clamping space. According to the invention, the clamping space is used for clamping the plate-like fan blade frame, and the fan blade is tightly fastened by a bolt penetrating through the installation through hole and is hard to loose; furthermore, the fan blade is simple in structure and high in safety degree.

Description

(1) Technical field [0001] The invention relates to a fan blade. (2) Background technology [0002] The fan blades of industrial fans are generally long and heavy, and their installation position is often located on the top of the center of the factory building. During the operation of the fan, due to the vibration and airflow fluctuation caused by the rotation, the fan blades are easily detached from the fan frame. , or even broken, will cause personal injury to the staff working under the fan. In order to reduce the weight of the fan blades, the fan blades are made hollow, but the problem of how to securely install the hollow fan blades on the fan frame has been puzzling people. (3) Contents of the invention [0003] The purpose of the present invention is to provide a fan blade which can be firmly installed on the fan frame and increase the use safety. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A fan...
