Description

Technical Field

[0001] The utility model relates to the technical field of combined fan blades, in particular to a combined fan blade fixing component. 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, the traditional method is to connect the fan body to the surface of the driving rotating rod, and then use multiple bolts to fix it. As time goes by, due to the large rotational power and vibration, the bolts may become loose, resulting in separation from the connection between the two. If separated, the fan body cannot operate synchronously with the rotating rod, which may cause unstable operation of the equipment or even accidents, and will also cause a certain degree of wear and tear, reducing the service life of the fan body. In addition, due to the fixation formed by multiple bolts, when maintenance is required, the disassembly process is more cumbersome due to too many bolts. Utility Model Content

A limit rod 113 is arranged inside the sleeve 17, a triangular plate 112 is arranged at one end of the limit rod 113, a spring 114 is arranged on one side of the triangular plate 112, an octagonal block 115 is arranged on the outside of the sleeve 17, a fan main frame 15 is arranged on the outside of the octagonal block 115, an embedded plate 14 is arranged at the middle end of the fan main frame 15, a chuck 13 is arranged at one end of the embedded plate 14, a fan main shaft 11 is arranged at one end of the chuck 13, a sleeve 17 is arranged inside the fan main shaft 11, one side of the fan main shaft 11 is fixedly connected to one end of the guide rod 12, and the guide rod 1 The end away from the fan blade main shaft 11 is clamped with the inside of the fan blade main frame 15, the inside of the fan blade main frame 15 is fixedly connected with the outside of the sleeve 17, the inner wall of the sleeve 17 is connected with the two ends of the two inclined plates 18, the upper and lower ends of the spring 114 are fixedly connected between the two inclined plates 18, one end of the two inclined plates 18 is movably connected with one end of the two connecting arms 110, the middle end of the connecting arm 110 is movably connected with the inner wall of the fixing frame 111, the upper and lower ends of the fixing frame 111 are fixedly connected with the inner surface of the sleeve 17, the outer side of the sleeve 17 is connected with the octagonal block 11 5, the outer side of the octagonal block 115 contacts one side of the fan blade main frame 15, the inside of the sleeve 17 is slidably connected to the outer side of the limiting rod 113, one end of the limiting rod 113 is fixedly connected to one end of the triangular block, one end of the triangular block is fixedly connected to one end of the spring 114, one end of the spring 114 away from the triangular block is fixedly connected to one side of the inner wall of the sleeve 17, the surface of the triangular block contacts one end of the two connecting arms 110, the outer side of the sleeve 17 contacts the inside of the fan blade main frame 15, and the inner side of the fan blade main frame 15 is clamped with one end of the inclined plate 18.

[0026] In this embodiment, when the staff is operating, the four holes on the fan blade main frame 15 are aligned with the guide rod 12, and then the fan blade main frame 15 is pushed. During the pushing process, the sleeve 17 will gradually enter the interior of the fan blade main shaft 11, and then the inclined plate 18 will be temporarily contracted in the sleeve 17 due to the limitation of the interior of the fan blade main shaft 11. At this time, the inclined plate 18 will continue to be pushed, and the inclined plate 18 will enter another space of the fan blade main frame 15. At the same time, the inclined plate 18 will be released without being subjected to pressure. The elastic sheet 19 will be released, and the inclined plate 18 will be ejected from the sleeve 17, and one end of the inclined plate 18 will be clamped at the edge of the interior of the fan blade main frame 15, so that the fan blade main shaft 11 and the fan blade main frame 15 are combined, ensuring that they maintain a certain relative position and movement relationship during work, and compared with other complex connection methods, a quick connection and combination is achieved;

[0027] Secondly, when it is necessary to separate the fan blade main shaft 11 and the fan blade main frame 15, it is only necessary to squeeze the limit rod 113. During the squeezing process, the triangular block is affected by the power and will move synchronously, so that one end of the two connecting arms 110 will be pushed up in different directions, while the other end will be pressed down, causing pressure on the inclined plate 18, causing it to squeeze the spring piece 19 again and shrink into the sleeve rod at the same time. Then the staff will take the sleeve 17 out of the fan blade main shaft 11 and the fan blade main frame 15. In addition, when the limit rod 113 is not subjected to pressure, the spring 114 is released to reset the limit rod 113 again, which will not affect the next use. The installed octagonal block 115 is embedded in the groove of the fan blade main frame 15 when the sleeve 17 enters the fan blade main frame 15, making the fan blade main frame 15 and the fan blade main shaft 11 more stable during the synchronous movement. In addition, this method does not require complicated tools or steps, simplifies the operation process, and improves operation efficiency.

[0028] Example 2

[0029] like Figure 1-Figure 5 As shown, the outer side of the guide rod 12 is clamped with the inner side of the fan blade main frame 15, the middle end of the fan blade main frame 15 is fixedly connected to the outer side of the embedded disk 14, one end of the embedded disk 14 is clamped with one end of the chuck 13, and the other end of the chuck 13 is movably connected to one side of the fan blade main shaft 11. A bolt 16 is threadedly connected between the chuck 13 and the embedded disk 14, and one side of the fan blade main frame 15 is in contact with one side of the fan blade main shaft 11.

[0030] In this embodiment, when the fan blade main shaft 11 and the fan blade main frame 15 are connected, the chuck 13 is first rotated and pre-adjusted so that its protruding part can be combined with the groove part of the embedded plate 14, and then the two are fixedly connected using the bolt 16. At the same time, the fan blade main shaft 11 and the fan blade main frame 15 will be tighter, which can effectively reduce the shaking and friction between the fan blade main shaft 11 and the fan blade main frame 15, thereby reducing the degree of wear between them, which helps to extend the service life of the equipment, reduce the frequency of maintenance and replacement of parts, and reduce maintenance costs, which can further ensure the stability and reliability of the connection. This method can reduce the shaking and instability of the equipment during operation and improve the safety of the equipment.

[0031] Working principle:

[0032] like Figure 1-Figure 5 As shown, in use, according to the needs of the user, the four holes on the fan blade main frame 15 are aligned with the guide rod 12, and then the fan blade main frame 15 is pushed. During the pushing process, the sleeve 17 will gradually enter the interior of the fan blade main shaft 11, and then the inclined plate 18 will be temporarily contracted in the sleeve 17 due to the limitation of the interior of the fan blade main shaft 11. At this time, the inclined plate 18 will enter another space of the fan blade main frame 15 if the pushing is continued. At the same time, the inclined plate 18 will be released without being subjected to pressure, and the inclined plate 18 will be ejected from the sleeve 17, and one end of the inclined plate 18 will be clamped at the edge of the interior of the fan blade main frame 15, so that the fan blade main shaft 11 and the fan blade main frame 15 are combined to ensure that they maintain a certain relative position and movement relationship during work;

[0033] By rotating and adjusting the chuck 13, the protruding part can also be combined with the embedded disk 14. In this way, when the fan blade main shaft 11 and the fan blade main frame 15 are combined, it can not only ensure that the two can move synchronously, but also reduce the wear between the two. Subsequently, the chuck 13 and the embedded disk 14 are adjusted with bolts 16 to further enhance the stability during the movement, thereby avoiding the gap at the connection between the chuck 13 and the embedded disk 14 from becoming larger as the equipment continues to operate during use. This method can reduce the instability of the equipment during operation.

[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.
