Description

Technical Field

[0001] The utility model relates to the technical field of fan blade components, in particular to a high-strength plastic fan blade. Background Art

[0002] Plastic fan blades refer to fan blades made of plastic. They are mainly used in fans, ventilation equipment, air conditioners and other equipment. Plastic fan blades can create airflow through rotation, promote air circulation, and control indoor temperature and humidity. In the industrial production process, plastic fan blades can also be used for exhaust and ventilation to maintain air circulation at the production site.

[0003] When installing some existing plastic fan blades, the user usually uses a mounting tool and then bolts to fix them on the connecting rod. However, if the fan blades are only fixed with bolts, the bolts may become loose after long-term use, resulting in reduced fixing strength. If the user uses it again, the fan blade may deviate and collide with other parts, causing damage, requiring the user to repair or replace it, which affects the user's use. Utility Model Content

[0009] As a preferred embodiment, a first gasket is fixedly connected to the surface of each of the plurality of fixing members, and a threaded portion is formed at one end of each of the plurality of fixing members away from the back side of the gasket.

[0010] As a preferred implementation, the plurality of fixing members are threadedly connected to the inner wall of the fixing shell via the threaded portions.

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.

[0025] Example 1

[0026] like Figure 1 - Figure 3As shown, the utility model provides a technical solution: a high-strength plastic fan blade, comprising: a fixing mechanism 1, the fixing mechanism 1 comprises a connecting rod 11, a protective mechanism 2 is arranged on one end surface of the connecting rod 11, a base 12 is arranged on the surface of the connecting rod 11, two limiting rings 13 are connected to the surface of the base 12, a fan blade 14 is arranged between the two limiting rings 13, a plurality of slots opened on one side of the base 12 are provided with fixing members 15 on the inner walls thereof, a plurality of fixing members 15 are provided with a first gasket 16 on one end surface thereof, a plurality of fixing members 15 are provided with a threaded portion 17 on the other end surface thereof, a second gasket 110 is connected to the surface of the threaded portion 17 of the plurality of fixing members 15, a hexagonal nut 111 is connected to the surface of the threaded portion 17 of the plurality of fixing members 15, a fixing shell 18 is arranged on the end surface of the connecting rod 11 away from the base 12, and a fixing shell 18 is arranged on the inner wall of the slot opened by the fixing shell 18.

[0027] In this embodiment, the card slot opened in the center of the base 12 contacts the surface of the connecting rod 11, and two limit rings 13 are fixedly connected to the surface of the base 12, and the two limit rings 13 are fixedly connected to one side of the fan blade 14; the above components cooperate to open a card slot in the center of the base 12 and contact the surface of the connecting rod 11 to achieve a more secure connection. This contact method can provide a larger contact area, increase the firmness of the connection, and thus improve the fixing strength of the fan blade 14;

[0028] The inner walls of four grooves equidistantly arranged in an annular shape on one side of the base 12 are all slidably connected with fixing members 15, and first gaskets 16 are fixedly connected to the surfaces of multiple fixing members 15. Threaded portions 17 are arranged at one end of multiple fixing members 15 away from the back side of the gaskets, and multiple fixing members 15 are threadedly connected to the inner wall of the fixing shell 18 through the threaded portions 17. Through the cooperation of the above components, when the staff installs, they can first move to the surface of the connecting rod 11 through the grooves arranged on the base 12, and move the base 12 to the surface of the fixing shell 18 through the grooves arranged thereon, and then rotate the fixing member 15 to threadably fix the fixing member 15 with the threaded tube 19 to form a limit. After the thread is fixed, the base 12 and the fixing shell 18 will also form a limit. The first gasket 16 can make the end of the fixing member 15 with the handle closer to it to avoid sliding, thereby avoiding the movement of the fixing member 15 caused by shaking. The limit can be formed by rotating the fixing member 15 and threadably fixing it with the threaded tube 19. Once the threads are fixed, a limit is formed between the base 12 and the fixing shell 18, ensuring a stable fixing state. This multiple limit fixing method can effectively prevent the fan blade from shaking and moving, and improve the reliability of fixing;

[0029] The surface of the threaded portion 17 of the fixing member 15 is in contact with the second gasket 110, and the surface of the threaded portion 17 of the plurality of fixing members 15 is in threaded connection with the inner wall of the corresponding hexagonal nut 111, the slot provided in the center of the fixing shell 18 is fixedly connected with the surface of the connecting rod 11, the surface of the fixing shell 18 is in contact with the inner wall of the slot provided in the base 12, and the inner wall of the fixing shell 18 is fixedly connected with a plurality of threaded tubes 19; after the staff has completed the preliminary installation, the second gasket 110 can be slid to the surface of the threaded portion 17, so that the second gasket 110 is close to the back side of the fixing shell 18, and then the second gasket 110 is squeezed by installing the hexagonal nut 111, thereby avoiding loosening caused by long-term use, thereby increasing the overall fixing strength of the fan blade 14, and the fixing strength of the fan blade 14 can be further strengthened by sliding the second gasket 110 to the surface of the threaded portion 17 and squeezing the second gasket 110 by installing the hexagonal nut 111. This design can effectively prevent loosening caused by long-term use and ensure the fixity and stability of the fan blade 14.

[0032] In this embodiment, by cooperating with the above components, a stable connection can be achieved through the fixed connection between the inner wall of the housing 21 and the outer side of the protection rod 22, and the rotational connection between the surface of one end of the connecting rod 11 and the inner wall of the slot opened on one side of the protection rod 22. This design can effectively avoid instability caused by looseness and ensure the safety and reliability of the device during operation.

[0033] Working principle:

[0034] like Figure 1 - Figure 4As shown, when the staff is installing it, they can first move it to the surface of the connecting rod 11 through the slot opened on the base 12, and move the base 12 to the surface of the fixed shell 18 through the slot opened therein, and then rotate the fixing member 15 to make the fixing member 15 and the threaded tube 19 threadedly fixed to form a limit. After the thread is fixed, the base 12 and the fixed shell 18 will also form a limit. The first gasket 16 can make the end of the fixing member 15 with the handle closer to it to avoid sliding. After the staff has completed the preliminary installation, they can slide the second gasket 110 to the surface of the threaded portion 17 so that the second gasket 110 is close to the back side of the fixed shell 18, and then install the hexagonal nut 111 to squeeze the second gasket 110, thereby avoiding loosening caused by long-term use, thereby increasing the overall fixing strength of the fan blade 14, and the fixing strength of the fan blade 14 can be further strengthened by sliding the second gasket 110 to the surface of the threaded portion 17 and installing the hexagonal nut 111 to squeeze the second gasket 110.
