[0002] Plastic fan blades, as the name implies, are a kind of rotating parts made of plastic materials used in equipment such as fans or air conditioners. It is usually made of high-strength, wear-resistant engineering plastics, and has the characteristics of light weight, corrosion resistance, and insulation.

[0003] The main function of plastic fan blades is to generate airflow through rotation, thereby achieving heat dissipation, ventilation, cooling and other effects. Compared with traditional metal fan blades, plastic fan blades have lower weight and better corrosion resistance. Therefore, plastic fan blades are more suitable in some special environments, such as high temperature, humidity or chemical corrosion.

[0004] In the existing technology, existing plastic fans usually use a variety of disassembly tools and screws to install the fan blades on the rotating rod. The operation steps during the disassembly or installation process are relatively complicated. Due to the large variety of disassembly tools, the staff needs to spend extra time and energy to find and prepare the corresponding tools. Secondly, since the material of plastic fan blades is relatively soft, it is easy to be deformed or damaged by external forces. Therefore, during the disassembly process, if you are not careful, the fan blades or internal components may be damaged. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a plastic fan blade with an easy-to-replace function, comprising: a disassembly mechanism 1, the disassembly mechanism 1 comprises a protective shell 11, a support frame 12 is arranged inside the protective shell 11, a motor 13 is arranged at one end of the support frame 12 away from the inner wall of the protective shell 11, one end of the support frame 12 is fixedly connected to the inner wall of the protective shell 11, the other end of the support frame 12 is fixedly connected to the outer surface of the motor 13, the inner wall of the protective shell 11 is annularly equidistantly provided with limiting grooves 14, a fan blade 15 is arranged at one end of the motor 13, a threaded groove 16 is arranged inside the fan blade 15, a rotating rod 17 is arranged between the fan blade 15 and the motor 13, the output end of the motor 13 is fixedly connected to one end of the rotating rod 17, and the other end of the rotating rod 17 is threaded. A fixing tube 18 is provided on the outer surface of the rotating rod 17 through the center of the fan blade 15. The outer surface of the rotating rod 17 is fixedly connected to the inner surface of the fixing tube 18. The outer surface of the fixing tube 18 is threadedly connected to the threaded groove 16 opened inside the fan blade 15. A threaded portion 19 is provided at the end of the rotating rod 17 away from the motor 13. A rubber gasket 110 is provided on the side of the fan blade 15 away from the motor 13. The rubber gasket 110 is nested in the end of the rotating rod 17 away from the motor 13 and contacts with the side of the fan blade 15 away from the motor 13. A hexagonal nut 111 is provided on the side of the rubber gasket 110 away from the fan blade 15. The inner surface of the hexagonal nut 111 is threadedly connected to the threaded portion 19. An auxiliary mechanism 2 is provided on the side of the protective shell 11 close to the limiting groove 14.

[0028] In this embodiment, when the staff needs to disassemble and replace the plastic fan blade 15, since the traditional disassembly method requires the use of multiple disassembly tools to assist in disassembling the fan blade 15, and thus the disassembly requires a lot of time and effort, in this device, the staff only needs to remove the air outlet cover 21, rotate the hexagonal nut 111 counterclockwise, and remove it and the rubber gasket 110 from the rotating rod 17. The hexagonal nut 111 and the rubber gasket 110 will have a certain fixing effect on the fan blade 15 to prevent the fan blade 15 from loosening during rotation. Then, when the staff rotates the fan blade 15 counterclockwise, the threaded groove 16 inside the fan blade 15 will be released from the fixing tube 18, and the staff can take out the fan blade 15 and replace it, thereby improving the staff's replacement efficiency. The support frame 12 provides effective support for the motor 13 and other components to ensure that the equipment can operate normally during operation.

[0029] Example 2

[0030] like Figure 1-Figure 4 As shown, the auxiliary mechanism 2 includes an air outlet cover 21 , and a limiting block 22 adapted to the limiting groove 14 is fixedly connected to the outer ring of the air outlet cover 21 , and the limiting block 22 is butted against the limiting groove 14 .

[0031] In this embodiment, the air outlet cover 21 can provide protection for the fan blades 15 and other internal components to prevent external factors from affecting the internal components. The adaptation of the limit block 22 and the limit groove 14 enables the air outlet cover 21 to be firmly fixed on the protective shell 11. When the limit block 22 is docked with the limit groove 14, the friction force and locking mechanism between the two can provide sufficient stability to prevent the air outlet cover 21 from accidentally falling off or loosening during use. When the staff needs to take out the air outlet cover 21, they only need to pull the air outlet cover 21 with a little force to take it out.

[0032] Working principle:

[0033] like Figure 1-Figure 4 As shown, when the staff needs to disassemble and replace the plastic fan blade 15, they first need to pull the air outlet cover 21 with a little force, and then the limit block 22 will disengage from the limit groove 14, and the staff can take the air outlet cover 21 out of the protective shell 11, and then rotate the hexagonal nut 111 counterclockwise, the inner surface of the hexagonal nut 111 will rotate with the threaded portion 19 at one end of the rotating rod 17, and then remove it and the rubber gasket 110 from the rotating rod 17, and the staff rotates the fan blade 15 counterclockwise, and the threaded groove 16 inside the fan blade 15 will rotate with the outer surface of the fixing tube 18, and then the fan blade 15 and the fixing tube 18 will be released. The staff can take out the fan blade 15 and replace it.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
