DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0019] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution 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 Figures 1-6As shown, this specific embodiment adopts the following technical scheme: it includes: a turntable, a fixed cover, fan blades, a slider, and a spring. The circumferential side of the turntable is provided with a mounting groove for plugging in the fan blades. The central part of the turntable is fixedly connected to the motor housing. A lampshade is provided under the turntable, and a light source is provided in the lampshade. A platform is provided in the turntable, and screw holes, positioning pin holes and limiting grooves are provided on the platform. The fixed cover is fixed on the turntable, and a trapezoidal push block is provided on the fixed cover. A slider connecting component is provided on the turntable, and the slider is provided in the limiting groove and connected to the slider connecting component. Both ends of the spring are respectively connected to the slider connecting components, and the ends of the fan blades are provided with positioning grooves and undercuts on both sides.

[0021] In which, the central part of the turntable is fixedly connected to the motor housing by screws, the turntable is fixedly connected to the fixing cover by screws and positioned by positioning pin holes, and there is a gap between the turntable and the fixing cover for inserting the fan blades; the fixing cover is provided with a cross-shaped limiting ridge, and the bottom of the fixing cover is provided with a positioning ridge, the fixing cover is located on the fan blade, and the positioning groove at the end of the fan blade cooperates with the positioning ridge of the fixing cover to achieve limitation; the trapezoidal push block is provided with a groove adapted to the cross-shaped limiting ridge of the fixing cover, and the trapezoidal push block is located on the fixing cover, and the trapezoidal push block is pushed inward, and the trapezoidal structure is used to move the slider to both sides to disengage from the undercut of the fan blade, thereby completing the unlocking of the fan blade; and the unlocking direction of the trapezoidal push block is opposite to the direction of the centrifugal force applied to the fan blade when it rotates.

[0022] In addition, the slider is fixedly connected to the slider connecting component by screws, and the slider is clamped into the inverted locking fan blade by spring tension.

[0023] The working principle of this specific embodiment is as follows: insert the end of the fan blade into the mounting groove of the side wall of the turntable and insert it along the positioning groove. During the insertion process, the end of the fan blade contacts the slider and the thrust is used to move the slider outward along the limiting structures on both sides, while stretching the spring; when inserted into place, the spring is reset by elastic force to make the slider press against the undercut, so as to realize self-locking and fixation of the fan blade, push the trapezoidal push block inward, and use the trapezoidal structure to drive the slider to move to both sides, disengaging the lock of the undercut. At this time, the fan blade can be pulled out of the square groove to complete the disassembly; the locking direction of the slider is consistent with the direction of the centrifugal force when the fan is running (tightening outward). When the fan rotates at high speed, the centrifugal force causes the slider to further press the undercut to ensure that the fan blade will not loosen.

[0024] In this specific embodiment, the fan blades can be disassembled by pushing the trapezoidal push block inward, and the spring tension is used to make the slider press against the undercut to achieve self-locking of the fan blades. The centrifugal force principle is combined to improve operational safety, and the overall stability is improved through the positioning structure.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
