Description

Technical Field

[0001] The present application relates to the technical field of fan blades for adjustable angles, and in particular, to a fan blade for adjustable angles. Background Art

[0002] A fan is an environmental protection device widely used in industrial production for dust removal. It consists of an electric motor and an impeller that rotates connected to the electric motor. The impeller forms a negative pressure inside the fan housing by rotating to complete the operation of blowing and dust removal. Since the impeller rotates at a relatively high speed during operation, it is very easy to generate eccentric rotation. Therefore, it is necessary to strengthen the rigid structure of the fan to ensure the operation quality of the fan.

[0003] During the assembly and welding process of the fan blades, due to the inconsistency of the workers, the blades will undergo a certain deformation due to heat during the welding process. It is very difficult to change the fan structure after assembly. Generally, the blades are reset by the workers pulling and tugging the blades. However, this method will cause the angles between the blades to be uneven, and the angles of the blades are different, resulting in different wind resistances of the blades. The increased wind resistance will reduce the efficiency of the fan. Therefore, those skilled in the art have provided a fan blade for adjustable angles to solve the problems raised in the above background art. Utility Model Content

[0004] In order to solve the problems raised in the above background art, the present application provides a fan blade for adjustable angles.

[0005] The fan blade for adjustable angles provided by the present application adopts the following technical solutions:

[0013] In some embodiments, a limiting hole is provided on one side of the collar, and a fixing bolt is disposed inside the limiting hole.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] (1) The worker first welds the fixed seat to the surface of the rotating disk at equal intervals, and installs a transmission disk inside the rotating disk for connection with the output end of the motor body. The limit column and the connecting column are an integrated structure. Then the worker inserts the limit column into the interior of the fixed seat, and then covers the fixed assembly on the surface of the fixed seat and the limit column to increase the stability of the connection structure between the fixed seat and the limit column. Then, the fan blade is welded at one end of the connecting column. In this way, the limit column, the connecting column and the welded fan blade are connected as an integrated whole, and then the limit column and the fixed seat are assembled to facilitate the installation and disassembly of the connecting column and the welded fan blade.

One side of the top block extends outward and wraps around the surface of the connecting column, increasing the structural strength between the connecting column and the limit column, making the connection between the limit column and the connecting column less likely to deform.

Detailed implementation manners

[0022] The following will Figures 1-4 further describe the present application in detail.

[0023] The embodiment of the present application discloses a blower blade for adjustable angle. Referring to Figures 1-4 , a blower blade for adjustable angle includes a motor body 1, a fixing component 5 and a connecting column 7. One output end of the motor body 1 is fixedly connected with a transmission disk 2 through a coupling. A rotating disk 3 is arranged on the surface of the transmission disk 2. One side of the surface of the rotating disk 3 is provided with a fixing base 4. A plurality of fixing bases 4 are arranged at equal intervals. Limiting columns 6 are arranged inside each of the plurality of fixing bases 4. The fixing component 5 is arranged on the surfaces of the fixing base 4 and the limiting column 6. The fixing component 5 is arranged around the rotating disk 3. The connecting column 7 is arranged at one end of the limiting column 6. A fan blade 8 is arranged at the end of the connecting column 7 far from the limiting column 6;

[0024] In this way, during the implementation process, when workers need to assemble the fan blades 8, the workers first weld the fixing seat 4 to the surface of the rotating disk 3 at equal distances, and install the transmission disk 2 inside the rotating disk 3 for connecting with the output end of the motor body 1. The limiting column 6 and the connecting column 7 are an integrated structure. Then the workers will insert the limiting column 6 into the interior of the fixing seat 4, and then cover the fixing assembly 5 on the surface of the fixing seat 4 and the limiting column 6 to increase the stability of the connection structure between the fixing seat 4 and the limiting column 6, and then weld the fan blades 8 at one end of the connecting column 7. In this way, the limiting column 6, the connecting column 7 and the welded fan blades 8 are integratedly connected, and then the limiting column 6 and the fixing seat 4 are assembled to facilitate the installation and disassembly of the connecting column 7 and the welded fan blades 8. Then, by changing the angle of the limiting column 6 located inside the fixing seat 4, the angle of the fan blades 8 is changed, so that multiple groups of fan blades 8 are kept at a uniform angle, so that the wind resistance difference between multiple groups of fan blades 8 is reduced, and the efficiency of the motor body 1 during rotation is improved.

[0025] The fixed seat 4 has a limit slot 41 formed inside, and a plurality of limit slots 41 are formed at equal intervals. The surface of the limit column 6 is fixedly connected to a limit slider 61, and a plurality of limit sliders 61 are provided. The plurality of limit sliders 61 are located inside the limit slot 41 and slide in contact with the inner wall of the limit column 6.

[0026] The limiting groove 41 is used to limit the limiting column 6. The limiting column 6 is embedded in the limiting groove 41 through the limiting slider 61. The angle between the limiting column 6 and the fixed seat 4 is changed by changing the angle at which the limiting slider 61 is embedded in the limiting groove 41. When the fixed seat 4 rotates, the two sides of the limiting slider 61 will fit tightly with the inner wall of the fixed seat 4, so as to avoid the limiting column 6 from rotating during the rotation process, thereby increasing the stability of the connection structure between the fixed seat 4 and the limiting column 6.

[0027] Preferably, a limiting block 62 is provided at one end of the limiting column 6 away from the limiting column 6, a limiting groove 42 is provided at the bottom of the fixing seat 4, and one end of the limiting block 62 is located inside the limiting groove 42 and fixedly engaged with the inner wall of the fixing seat 4;

[0028] The fixing seat 4 limits the limiting block 62 through the limiting groove 42. When the limiting column 6 is inserted into the fixing seat 4, the inner wall of the bottom of the fixing seat 4 will fit with the limiting column 6. When one end of the limiting column 6 fits with the inner wall of the fixing seat 4, the limiting block 62 will be inserted into the limiting groove 42, thereby increasing the strength of the connection structure between the fixing seat 4 and the limiting column 6.

[0029] Specifically, a reinforcing rib 9 is fixedly connected to one side of the rotating disk 3, and a plurality of reinforcing ribs 9 are provided, one end of the plurality of reinforcing ribs 9 is fixedly connected to the transmission disk 2, and the other ends of the plurality of reinforcing ribs 9 are respectively fixedly connected to the plurality of fixing seats 4;

[0030] The reinforcing rib 9 protrudes from the surface of the rotating disc 3. Both sides of the reinforcing rib 9 are arc-shaped to reduce wind resistance. The two ends of the reinforcing rib 9 respectively support the fixed seat 4 and the transmission disc 2, increasing the structural strength of the connection between the transmission disc 2 and the fixed seat 4 and the rotating disc 3, and minimizing the deformation of the rotating disc 3 during rotation.

[0031] More specifically, the fixing assembly 5 includes a collar 51 sleeved on the surface of the fixed seat 4. A top ring 53 is arranged on one side of the collar 51. The top ring 53 is sleeved on the surface of the limit post 6. A top block 54 is arranged inside the top ring 53. One side of the top block 54 is in contact with one end of the limit post 6. The top block 54 is sleeved on the surface of the connecting post 7.

[0032] The collar 51 and the top ring 53 are integrally connected. The worker first sleeved the collar 51 on the surfaces of the limit post 6 and the connecting post 7, and then welded the connecting post 7 to the fan blade 8. When the limit post 6 is inserted into the inside of the fixed seat 4, the collar 51 will slide on the surface of the fixed seat 4. When the limit post 6 completely enters the inside of the fixed seat 4, the top block 54 inside the top ring 53 will be in contact with one side of the fixed seat 4 and the limit post 6, minimizing the sliding of the limit post 6 inside the fixed seat 4. One side of the top block 54 extends outward to wrap around the surface of the connecting post 7, increasing the structural strength between the connecting post 7 and the limit post 6 and making the connection between the limit post 6 and the connecting post 7 not easily deformed.

[0033] During further implementation, a limit hole 52 is opened on one side of the collar 51. A fixing bolt 55 is arranged inside the limit hole 52. The limit hole 52 is used to limit the fixing bolt 55. One end of the fixing bolt 55 is inserted into the inside of the limit hole 52 and then threadedly inserted into the outer wall of the fixed seat 4 of the collar 51, and the fixing bolt 55 fixes the collar 51 and the fixed seat 4 together.

[0034] The implementation principle of the adjustable-angle fan blade in the embodiment of the present application is as follows:

[0035] When the worker needs to assemble the fan blade 8, the worker first welds the fixed seats 4 equidistantly on the surface of the rotating disc 3. A transmission disc 2 is installed inside the rotating disc 3 for connection with the output end of the motor body 1. The limit post 6 and the connecting post 7 are of an integral structure. Then the worker inserts the limit post 6 into the inside of the fixed seat 4, and then covers the fixing assembly 5 on the surfaces of the fixed seat 4 and the limit post 6 to increase the stability of the connection structure between the fixed seat 4 and the limit post 6. Then welds the fan blade 8 at one end of the connecting post 7. In this way, through the integral connection of the limit post 6, the connecting post 7 and the welded fan blade 8, and then through the assembly of the limit post 6 and the fixed seat 4, it is convenient for the installation and disassembly of the connecting post 7 and the welded fan blade 8. Then, by changing the angle of the limit post 6 inside the fixed seat 4, the angle of the fan blade 8 is changed, so that multiple groups of fan blades 8 are kept at the same angle, reducing the wind resistance difference between multiple groups of fan blades 8 and improving the efficiency of the motor body 1 during rotation.
