Description

Technical Field

[0001] The utility model relates to the technical field of fan blades, in particular to a wear-resistant plastic fan blade. Background Art

[0002] A fan blade is a rotating component used to generate airflow, and is usually used in fans, air conditioners, ventilation equipment, etc. Its main function is to generate airflow through rotation so as to discharge heat, moisture or odor from an area and send fresh air into the area.

[0003] In the existing technology, when the fan blades are used in the air conditioner outdoor unit, since the fan blades need to rotate at high speed during use, the fan blades are first connected to the rotating rod, then fixed with bolts, and finally the air conditioner power output shaft rotates at high speed. As time goes by, due to the centrifugal force and friction generated by high-speed rotation, wear and damage may occur between the fan blades and the rotating rod. Long-term use and frequent operation may cause the fan blades to lose balance or deform, thereby affecting the normal operation of the equipment. In addition, during rotation, a certain amount of vibration will be generated, and the vibration may cause the bolt components to loosen. Utility Model Content

[0022] 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.

[0023] Example 1

[0024] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a wear-resistant plastic fan blade, comprising: a fan blade main shaft 11, a screw rod 12 and a main frame 111 are respectively arranged on one side of the fan blade main shaft 11, a ball bearing 14 is arranged on the outer side of the screw rod 12, a snap ring 13 is arranged on the outer ring of the ball bearing 14, six arc grooves 112 are equidistantly arranged in an annular shape inside the snap ring 13, the main frame 111 is arranged on the inner surface of the arc groove 112, a turning handle 15 is arranged on one side of the inner ring of the ball bearing 14, a flower-shaped ring 18 is arranged on the outer side of the turning handle 15, a connecting plate 110 is arranged on one side of the flower-shaped ring 18, and a fixing Ring 16, five screws 19 are equidistantly arranged on the outer side of the fixing ring 16, six inserts 17 are arranged on the side of the fixing ring 16, the side of the fan blade main shaft 11 is fixedly connected to one end of the screw rod 12, the outer side of the screw rod 12 is threadedly connected to the inner ring of the ball bearing 14, the outer ring of the ball bearing 14 is fixedly connected to the inner surface of the middle end of the retaining ring 13, the arc groove 112 on the retaining ring 13 fits with the outer side of the main frame 111, the outer side of the turning handle 15 fits with the inner surface of the flower-shaped ring 18, one end of the side of the flower-shaped ring 18 is fixedly connected to one side of the connecting plate 110, and the outer side of the flower-shaped ring 18 is rotatably connected to the inner surface of the middle end of the fixing ring 16.

[0025] In this embodiment, when the staff is in use, the clamping ring 13 is pushed along the path of the main frame 111. When it is pushed to a certain extent, it is limited by the middle part of the screw rod 12. At this time, the inner ring of the ball bearing 14 is rotated by rotating the handle 15, and the inner ring is designed with a threaded groove. By continuously rotating the handle 15, the inner ring will be connected to the screw rod 12, and the clamping ring 13 will be moved again until it moves to the edge of the groove of the main frame 111. In this way, the contact between the fan blade and the fan blade main shaft 11 can be effectively avoided, and the wear on the fan blade can be reduced. If the fan blade contacts the fan blade main shaft 11, it will cause unnecessary wear and damage, which will affect the performance and life of the equipment. By using the structure of the clamping ring 13 and the screw rod 12, this situation can be avoided, thereby extending the service life of the equipment.

[0026] Secondly, by pre-adjusting the flower-shaped ring 18 so that it can fit into the groove on the turning handle 15, after the adjustment is completed, the fixing part is pushed along the path of the main frame 111 so that the inner surface of the flower-shaped ring 18 fits into the outer circle of the turning handle 15. The fit between the flower-shaped ring 18 and the turning handle 15 can ensure that the connection between the two is firm and stable, which helps to prevent problems such as loosening or falling off during operation, thereby improving the stability and reliability of the equipment.

[0027] Example 2

[0028] like Figure 1 - Figure 4 As shown, one side of the fixing ring 16 is fixedly connected to one end of the six embedded blocks 17, the side of the six embedded blocks 17 away from the fixing ring 16 is in contact with one side of the retaining ring 13, the two sides of the six embedded blocks 17 are fitted with the inner wall of the main frame frame 111, the outer side of the main frame frame 111 is fitted with the inner wall of the fixing ring 16, the inside of the fixing ring 16 is threadedly connected to the outer sides of the five screws 19, and one end of the five screws 19 is threadedly connected to the edge of one end of the main frame frame 111 away from the inside of the fixing ring 16.

[0029] In this embodiment, when the fixing ring 16 is connected to the main frame 111, the insert 17 is first matched with the groove on the main frame 111, so that the fixing ring 16 is confined in the main frame 111, and one end of the insert 17 will contact the clamping ring 13 to resist it from the side, so as to achieve precise positioning of the fixing ring 16 in the main frame 111, which helps to ensure the accurate assembly and stable operation of the equipment components, and can also effectively prevent the fixing ring 16 and the clamping ring 13 from being misplaced and swinging during use. Finally, the fixing ring 16 and the main frame 111 are connected and fixed with screws 19, and all components are fixed at the same time, which can improve the connection stability between them. Compared with other complex connection methods, screw 19 fixing is usually easier to implement, saving time and labor costs.

[0030] Working principle:

[0031] like Figure 1 - Figure 4 As shown, when the utility model is in use, according to the needs of the user, the snap ring 13 is pushed along the path of the main frame 111. When it is pushed to a certain extent, it is limited by the influence of the middle part of the screw rod 12. At this time, the inner ring of the ball bearing 14 is rotated by rotating the handle 15, and the inner ring is designed with a threaded groove. The inner ring is connected to the screw rod 12 by continuously rotating the handle 15, and the snap ring 13 is moved again until it moves to the edge of the groove of the main frame 111. In this way, the contact between the fan blade and the fan blade main shaft 11 can be effectively avoided, and the wear on the fan blade can be reduced. Finally, the flower-shaped ring 18 is matched with the handle 15, which helps to prevent loosening during operation.

[0032] The insert 17 is matched with the groove on the main frame 111 so that the fixing ring 16 is restricted in the main frame 111, and one end of the insert 17 will contact the clamping ring 13 to resist it from the side, which helps to ensure the accurate assembly and stable operation of the equipment components. Finally, the fixing ring 16 and the main frame 111 are connected and fixed with screws 19, and all components are fixed at the same time to improve the connection stability between them.

[0033] 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.
