DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0020] See Figure 1-Figure 5As shown, this specific embodiment adopts the following technical scheme: including: a first connecting rod, a second connecting rod, a rotating fixing cover, and a plastic fixing seat, one end of the first connecting rod is connected to the lamp pole, and the other end is provided with a limit point, the limit point is hooked with the torsion spring in the plastic fixing seat through elastic limit and reset, the end of the second connecting rod is provided with a limit structure, and the other end is connected to the fan blade, the rotating fixing cover is a sheet metal part and is provided with a flange, the plastic fixing seat is composed of an upper plastic fixing seat and a lower plastic fixing seat, the lower plastic fixing seat is provided with a protrusion, and the protrusion cooperates with the limit point to limit the starting position of the fan blade.

[0021] Among them, the first connecting rod is fixedly connected to the lamp pole by screws, and the second connecting rod is fixedly connected to the fan blade by screws; a card slot is provided on the edge of the plastic fixing seat, and the rotating fixing cover drives the plastic fixing seat to rotate synchronously by embedding the card slot through the flange; the limiting structure is a 10-degree angle limiting structure that limits the maximum swing angle of the fan blade to 10 degrees when rotating; the plastic fixing seat is fixedly connected by at least two connecting shafts, and the connecting shaft includes a fan blade opening rotation axis and a fan blade self-balancing rotation axis; the second connecting rod is fixedly connected to the rotating fixing cover by bolts, and the first connecting rod is fixedly connected to the rotating fixing cover and the plastic fixing seat by bolts.

[0022] The working principle of this specific embodiment is: when the fan is working, the driving motor drives the rotating fixed cover to rotate, and the plastic fixing seat rotates synchronously. When the fan blades rotate, the 10-degree angle limit structure at the end of the second connecting rod makes it contact with the limit surface, limiting the maximum swing angle of the fan blades to 10 degrees, thereby achieving centrifugal balance; during the process of expanding or closing the fan blades, the torsion spring uses elastic force to make the limit point on the first connecting rod cooperate with the convex point of the lower plastic fixing seat, thereby ensuring the precise starting position of the fan blades.

[0023] This specific implementation method can accurately define the starting position of the fan blades through the coordination of the limit point and the torsion spring force; and utilize the 10-degree angle limit structure to keep the fan blades in centrifugal balance; through the coordination of the fixed cover flange and the plastic fixing seat, synchronous rotation is achieved, thereby improving the stability and reliability of the fan light.
