Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically a device suitable for fan assembly that allows for adjustable assembly angles and uses shape to prevent mistakes. Background Technology

[0002] The angle of fan blades is generally fixed, but due to different application scenarios, the blade angle often needs to be adjusted. Current adjustment methods involve adjusting the entire fan, and cannot adjust the blade angle locally without changing the overall shape. Manufacturing methods include modular assembly and integral casting. In modular assembly, most existing fan assembly methods use screws to connect and fix the round holes on the fan blades to the round holes on the fan base, such as... Figures 1 to 3 As shown. In existing screw assembly methods, the round holes are generally of uniform shape and size for ease of processing. However, when multiple round holes are used on the fan blades to adjust the angle of the blades locally, it has been found that during actual manufacturing, assembly personnel lack differentiation due to the uniform shape and size of the holes, leading to assembly errors. External marking methods often become ineffective due to wear and dust accumulation. Utility Model Content

[0003] This invention provides a device suitable for fan assembly that allows for adjustable assembly angles and uses shape differentiation to prevent mistakes, thereby addressing the technical deficiencies of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention provides a device suitable for fan assembly that can adjust the assembly angle of fan blades and uses shape to prevent mistaken identification. Each fan blade includes multiple fan base assembly holes and the same number of fan blade assembly holes. The multiple fan blade assembly holes are evenly arranged in a circular shape at the blade assembly end. The positions of the multiple fan blade assembly holes correspond one-to-one with the fan base assembly holes. Any one of the multiple fan blade assembly holes has the same shape and size as the corresponding assembly hole on the fan base. Any one of the multiple fan blade assembly holes has a different shape from the other fan blade assembly holes. The device also includes assembly screws. The length of each assembly screw is equal to the depth of the corresponding one of the multiple fan blade assembly holes plus the depth of the corresponding assembly hole on the fan base. The screw has the same shape as the assembly hole and the lateral dimensions match.

[0005] Specifically, the number of mounting holes on the multiple fan bases is two.

[0006] Specifically, the two fan base mounting holes are cylindrical and square in shape.

[0007] Specifically, the fan base has 5 mounting holes.

[0008] Specifically, the five fan base mounting holes are cylindrical straight rod-shaped, cylindrical stepped, square, rectangular, and triangular.

[0009] Specifically, the screw is equipped with a washer.

[0010] Specifically, the mounting holes for the multiple fan blades are marked with corresponding angles.

[0011] Specifically, the marking method is stamping.

[0012] Because there are multiple fan blade mounting holes, and the shape of any one of these mounting holes is different from the shapes of the mounting holes on the other fan blades, the beneficial effect of this utility model is:

[0013] To achieve fan blade angle adjustment.

[0014] Using assembly holes of different depths, compared to circular holes of uniform depth, can ensure that no assembly problems occur during actual production. The mistake-proof design in the structural assembly can reduce unnecessary losses caused by human error. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0025] like Figures 4 to 7 As shown, the present invention provides a device suitable for fan assembly that allows adjustment of the fan blade assembly angle and uses shape differentiation for error prevention. Each fan blade 1 includes multiple fan base assembly holes 2 and the same number of fan blade assembly holes 3. The multiple fan blade assembly holes 3 are evenly arranged in a circular shape at the blade assembly end 4. The positions of the multiple fan blade assembly holes 3 correspond one-to-one with the fan base assembly holes 2. Any one of the multiple fan blade assembly holes 3 has the same shape and size as the assembly hole on the corresponding fan base 5. Any one of the multiple fan blade assembly holes 3 has a different shape from the other fan blade assembly holes 3. The device also includes assembly screws 6. The length of each assembly screw 6 is equal to the depth of the corresponding one of the multiple fan blade assembly holes 3 plus the depth of the assembly hole 2 on the corresponding fan base 5. The screw 6 has the same shape as the assembly hole and the lateral dimensions match. Setting multiple fan blade mounting holes 3 allows for different mounting angles of the fan blades 1 based on their varying positions, meeting the needs of specific work scenarios. However, during fan blade assembly, the fan blades 1 are in motion, and the multiple mounting holes 3 are evenly arranged circumferentially at the blade mounting end 4. This makes it easy for construction workers to mismatch the positions of the mounting holes 3 with the mounting angles of the fan blades 1, leading to rework, wasted manpower, and increased costs. External marking methods often lose their effectiveness due to wear and dust accumulation. This invention addresses this issue by using screws 6 with different shapes for each of the multiple fan blade mounting holes 3. When a worker screws in a screw 6, the mismatch in shape immediately alerts them to the error, allowing for timely correction and ensuring construction efficiency. Furthermore, this alert function remains effective over time and will not be lost due to wear or dust accumulation.

[0026] Specifically, the number of fan base mounting holes is two. Two fan base mounting holes can be used in some simple situations while saving costs.

[0027] Specifically, the two fan base mounting holes are cylindrical and square. The cylindrical shape is simple in structure and highly versatile, while the square shape can prevent the screws from rotating between the mounting holes.

[0028] Specifically, the fan base has five mounting holes, which maximizes the use of the fan's internal space and provides the most options.

[0029] Specifically, the five fan base mounting holes are cylindrical straight rods, cylindrical stepped shapes, squares, rectangles, and triangles. The cylindrical shape is simple in structure and highly versatile. The cylindrical stepped shape allows for precise positioning and alignment. The square shape prevents rotation between the screw and the mounting hole. The rectangular shape prevents rotation between the screw and the mounting hole. The triangular shape greatly prevents rotation between the screw and the mounting hole.

[0030] Specifically, the screw is equipped with a washer, which can prevent loosening, resist vibration, and distribute pressure.

[0031] Specifically, the mounting holes of the multiple fan blades are marked with corresponding angles, which not only prevents mistakes through physical structure but also further prevents mistakes through visual function.

[0032] Specifically, the marking method is stamping. The stamping method can ensure that the corresponding angle of the marking exists for a long time, and it is low in cost and will not cause additional interference to the construction personnel during assembly.

[0033] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
