Description

Technical Field

[0001] The present invention relates to the technical field of fan blade processing, and specifically relates to a placement rack structure for fan blades and a usage method thereof. Background Art

[0002] A fan blade is a component of a floor fan, a component that rotates driven by a motor to generate wind. The cross-section of a common household fan blade is generally curved. The width and angle of the fan blade of a fan are designed and depend on the load power of the motor. If only the rotation speed is considered without considering the motor power, then the angle of the fan blade is even more important. If the angles of the fan blades are the same, of course, the wider the fan blade, the stronger the wind. Moreover, the design and production of fan blades are presented as regular symmetric structures, so that a uniform and stable wind source can be generated. Common types of fans include three-blade fans, four-blade fans, five-blade fans, double-layer fans, etc.

[0003] In the prior art, during the production and transportation of fan blades, a placement rack is needed to place and transport the fan blades. When the conventional fan blade placement rack places the fan blades, there will be gaps between the fan blades. During the transportation of the fan blades, the fan blades will collide with each other. Moreover, it is time-consuming and laborious to count the fan blades after placement, and long-term placement will cause the fan blades to deform. During the use of the placement rack, the placement rack with fan blades installed cannot be effectively stacked, resulting in a large amount of space being consumed to place the fan blade placement rack. At the same time, the conventional placement rack cannot be disassembled and assembled, which brings inconvenience to transportation. Summary of the Invention

[0047] As a specific technical solution of this embodiment, the sides of the first rectangular frame 1 and the second rectangular frame 2 close to the fan blade body 5 are plane structures.

[0048] In this embodiment, the first rectangular frame 1 and the second rectangular frame 2 can better clamp the side of the fan blade body 5.

[0049] A method for using a placement rack for a fan blade includes the following steps:

Install the right bushing 401 on the right end of the central shaft 402, then insert the right ends of the bushing 401 and the central shaft 402 into the mounting hole 3 of the second rectangular frame 2, push the moving block 701 in the limiting mechanism 7 on the second rectangular frame 2 to move towards the central shaft 402, so that the locking pin 703 on the moving block 701 is inserted into the jack 9 on the bushing 401 and the central shaft 402, achieving the effect of fixedly connecting the second rectangular frame 2 and the left end of the central shaft 402. The first rectangular frame 1 and the second rectangular frame 2 clamp and fix the fan blade body 5 on the central shaft 402, making the placement of the fan blade body 5 more stable, avoiding bumps, and facilitating the counting of the number of fan blade bodies 5. During normal handling, the fan blade body 5 and the left and right first rectangular frames 1 and second rectangular frames 2 can be an integral structure and will not scatter.

During normal handling, the fan blade body 5 and the left and right first rectangular frames 1 and second rectangular frames 2 can be an integral structure and will not scatter. During warehouse storage, the fan blade body 5 will not deform after being placed for a long time, and can be mass-produced. The placement racks with fan blade bodies 5 can be stacked, greatly reducing the occupied space, facilitating packaging and transportation. At the same time, the central shaft 402 can be disassembled and assembled, enabling the placement rack itself to be disassembled and assembled, facilitating stacking, maintenance, recycling, and saving space.
