[0028] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown, a quick-install structure of a fan blade 2 of the present invention includes a blade fork 1 and a fan blade 2. The end of the blade fork 1 connected to the fan blade 2 is provided with a plug-in assembly 3 for plugging and matching with the fan blade 2. One end of the fan blade 2 that cooperates with the plug-in assembly 3 is a plug-in portion 20. The plug-in assembly 3 includes a plug-in plate 30 arranged on the end of the blade fork 1. A plug-in hole 31 for plugging and matching with the plug-in portion 20 is formed between the plug-in plate 30 and the blade fork 1. An elastic fixing piece 4 is provided in the plug-in hole 31 for pressing the plug-in portion 20 to prevent the fan blade 2 from falling off. The fan blade 2 of the present application is plugged and matched with the fan blade 2 by providing a plug-in assembly 3 at the end of the blade fork 1, which can facilitate users to quickly install the fan blade 2. Compared with the traditional method of directly fixing and locking the fan blade 2 and the blade fork 1 with bolts, it can be more convenient and quick. In addition, the present application is also provided with an elastic fixing piece 4, which can further press and fix the fan blade 2 to prevent the fan blade 2 from falling off, further improving the safety performance.

[0030] like Figures 2 to 5As shown, as a further embodiment of this embodiment, the bottom sides of the plug plate 30 extend outward to form connecting portions 32 that connect to the ends of the blade fork 1. The middle portion of the plug plate 30 rises upward to form a plug hole 31, and the plug hole 31 has a rectangular cross-section. After the manufacturer produces the fan components, personnel or mechanical equipment secure the connecting portion 32 to the blade fork 1 using screws or rivets. The blade fork 1 is then installed on the fan body and packaged together with the fan blades 2. Upon receipt, the user simply plugs the fan blades 2 into the plug holes 31 to complete the installation.

[0031] like Figures 2 to 5 As shown, as a further solution of this embodiment, limit holes 33 are formed on both sides of the insertion hole 31, and elastic clips 34 that can be deformed toward the inside of the insertion part 20 are formed on the left and right sides of the insertion part 20 of the fan blade 2. The outer side of the elastic clips 34 is formed with a locking protrusion 35 that engages with the limit holes 33. After the limit holes 33 are provided on the left and right sides of the insertion hole 31, after the insertion part 20 of the fan blade 2 is inserted into the insertion hole 31, the locking protrusions 35 in the elastic clips 34 on both sides will be locked into the limit holes 33 and locked, thereby preventing the fan blade 2 from falling off.

[0032] like Figures 2 to 5 As shown, as a further solution of this embodiment, the bottom of the engaging protrusion 35 abuts against the connecting portion 32. Arranging the bottom of the engaging protrusion 35 to abut against the connecting portion 32 can make the connection more stable. At the same time, since the structure of the connecting portion 32 is not damaged when the limiting hole 33 is provided, the connecting portion 32 can connect the front and rear parts of the limiting hole 33, thereby reducing the damage to the overall performance of the plug board 30 caused by the provision of the limiting hole 33.

[0033] like Figure 6 As shown, as a further solution of this embodiment, the front portion of the outer side of the clamping protrusion 35 is formed with a first inclined surface 36 for facilitating the insertion of the plug-in portion 20 into the plug-in hole 31, and the rear portion of the outer side of the clamping protrusion 35 is formed with a second inclined surface 37 for facilitating the withdrawal of the plug-in portion 20 from the plug-in hole 31 when the fan blade 2 is disassembled. After the first inclined surface 36 and the second inclined surface 37 are provided, the user can use the first inclined surface 36 to facilitate the insertion of the plug-in portion 20 into the plug-in hole 31 during assembly. Similarly, when the user needs to clean the fan blade 2, the second inclined surface 37 can be used to separate the plug-in portion 20 from the plug-in hole 31.

[0034] like Figures 2 to 5As shown, as a further solution of this embodiment, an opening 40 is formed on the plug board 30, and an elastic fixing piece 4 is formed on the opening 40. The elastic fixing piece 4 is formed on the opening 40 at an angle toward the end of the plug hole 31. By setting the elastic fixing piece 4 at an angle, the plug-in portion 20 can be tightly pressed into the plug hole 31, which can prevent the fan blade 2 from falling off. In addition, the elastic fixing piece 4 is set toward the plug hole 31, so that when the fan blade 2 is inserted, the plug-in portion 20 can enter the plug hole 31 more smoothly. It should be noted that in the present application, the entire structure of the plug board 30 is preferably made of plastic material, so that the contact between the elastic fixing piece 4 and the plug-in portion 20 of the fan blade 2 is non-rigid contact, which can not only press the plug-in portion 20, but also increase the friction force, thereby further preventing the fan blade 2 from falling off. In addition, a card slot (not shown in the figure) can be provided in the plug-in part 20 to cooperate with the elastic fixing piece 4. After the plug-in part 20 is inserted into the plug-in hole 31, the elastic fixing piece 4 is snapped into the card slot, which directly limits the card slot from falling off, and at the same time can press the plug-in part 20 to prevent the fan blades 2 from loosening. However, after the card slot is provided, the entire plug-in board 30 needs to be removed before the fan blades can be removed for later disassembly. Therefore, in this application, a solution without a card slot is preferably adopted.

[0035] like Figures 3 to 5 As shown, as a further solution of this embodiment, a reinforcing plate 5 is further provided on the plug plate 30 for strengthening the fixing strength of the plug plate 30. The cross-sectional shape of the reinforcing plate 5 matches the cross-sectional shape of the plug plate 30, and the left and right ends of the reinforcing plate 5 and the corresponding connecting portions 32 are fixed to the ends of the blade fork 1 by provided bolts. By providing the reinforcing plate 5, the strength of the plug plate 30 can be further improved, thereby further making the installation of the fan blade 2 more stable.

[0036] like Figures 3 to 5 As shown, as a further solution of this embodiment, the plug board 30 is provided with a plurality of positioning pins 6, and the reinforcing plate 5 is provided with positioning holes 60 corresponding to the positioning pins 6. After the positioning pins 6 are matched with the positioning holes 60, it is convenient for the staff to install.
