Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically a device suitable for fan assembly that can adjust the assembly angle and prevent mistakes based on depth. 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 depth as a distinguishing feature 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 fan blade assembly angle and prevent mistakes by differentiating the depth. Each fan blade includes a fan base assembly hole and multiple fan blade assembly holes. The multiple fan blade assembly holes are evenly arranged in a circular shape at the blade assembly end. The multiple fan blade assembly holes have the same diameter as the fan base assembly hole and are positioned correspondingly. The depth of any one of the multiple fan blade assembly holes plus the depth of the assembly hole on the fan base are different. The device also includes assembly screws, and 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 assembly hole on the fan base.

[0005] Specifically, the fan base has one mounting hole, while the multiple fan blade mounting holes have different depths.

[0006] Specifically, the fan base has multiple mounting holes, and the number of fan blade mounting holes is the same as the number of fan base mounting holes. The depth of each fan blade mounting hole plus the depth of the corresponding fan base mounting hole are different.

[0007] Specifically, the fan blades have five mounting holes.

[0008] Specifically, the screw is equipped with a washer.

[0009] Specifically, the mounting holes for multiple fan blades are marked with corresponding angles.

[0010] Specifically, the marking method is stamping.

[0011] Because there are multiple fan blade mounting holes, and the depth of any one of these mounting holes, plus the depth of the corresponding mounting hole on the fan base, is different, the beneficial effect of this utility model is:

[0012] To achieve fan blade angle adjustment.

[0013] 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

[0022] 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.

[0023] 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.

[0024] like Figures 4 to 7 As shown, the present invention provides a device for adjusting the assembly angle of fan blades and preventing mistaken insertion based on depth. Each fan blade 1 includes a fan base assembly hole 2 and multiple fan blade assembly holes 3. The multiple fan blade assembly holes 3 are evenly arranged in a circular pattern at the blade assembly end 4. The multiple fan blade assembly holes 3 have the same diameter as the fan base assembly holes 2 and are positioned correspondingly. The depth of any one of the multiple fan blade 1 assembly holes plus the depth of the assembly hole on the fan base 5 are all different. The device also includes assembly screws 6, the length of which 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 fan base. The design incorporates multiple fan blade mounting holes 3, whose different positions determine the different assembly angles of the fan blades 1 to meet the needs of specific work scenarios. However, during assembly, the fan blades 1 are in motion, and the multiple mounting holes 3 are evenly arranged in a circular pattern at the blade assembly end 4. This makes it easy for construction workers to mismatch the positions of the mounting holes 3 with the fan blade assembly angles, 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 the depth of any one of the multiple fan blade mounting holes 3, combined with the varying depths of the mounting holes on the fan base 5 and correspondingly different length screws 6. When construction workers screw in screws, if they find that the screws are too long or too short, they are promptly alerted to any errors, allowing for immediate correction and ensuring construction efficiency. Furthermore, this alerting function remains effective over time and will not be lost due to wear or dust accumulation.

[0025] Specifically, the fan base has one mounting hole, while the multiple fan blade mounting holes have different depths. The single mounting hole for the fan base can save costs.

[0026] Specifically, the fan base has multiple mounting holes, and the number of mounting holes for the multiple fan blades is the same as the number of mounting holes for the fan base. The depth of each mounting hole for the fan blades, plus the depth of the corresponding mounting hole for the fan base, is different. Through this many-to-many cooperation, multiple construction workers can operate simultaneously, improving work efficiency.

[0027] Specifically, the fan blades have five mounting holes, which maximizes the use of the internal space of the fan and provides the most options.

[0028] Specifically, the screw is equipped with a washer, which can prevent loosening, resist vibration, and distribute pressure.

[0029] Specifically, the mounting holes for multiple fan blades are marked with corresponding angles, providing not only physical structural error prevention but also visual error prevention.

[0030] 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.

[0031] 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.
