[0034] Embodiment 1

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, a building block fan includes: an outer frame 1, notches 4 are opened at the four corners of the top end of the outer frame 1, positioning guide rails 6 are fixedly connected to the four corners of the bottom end of the outer frame 1, and the cross-section of the positioning guide rail 6 is arranged in a T shape; a fan body 2, the fan body 2 is fixedly installed inside the outer frame 1; building blocks 3, the building blocks 3 are adapted to the notches 4, and the building blocks 3 are slidably fitted inside the notches 4; by inserting the building blocks 3 into the corresponding notches 4, the building blocks 3 and the outer frame 1 can form a whole, which is not only beautiful but also convenient for placing the building blocks 3 when not assembled.

[0036] Specifically, as Figure 2 shown, an inner chamfer 5 is opened at one corner inside the notch 4; the setting of the inner chamfer 5 not only facilitates the insertion of the building block 3 but also facilitates the fixing of the building block 3 in the notch 4.

[0037] Specifically, as Figure 2 shown, the protruding parts of the relative positioning guide rails 6 are arranged opposite to each other; this can facilitate the cooperation between the positioning guide rail 6 and the building block 3 and also facilitate the production of the building block 3.

[0038] Specifically, as Figure 3 shown, first positioning slide rail grooves 7 are opened on both sides of the building block 3 close to the inner wall of the notch 4, and the first positioning slide rail grooves 7 are slidably fitted to the outside of the positioning guide rail 6; when the building block 3 is inserted into the notch 4, the first positioning slide rail grooves 7 are aligned with the positioning guide rail 6 and the building block 3 is inserted downward, so that the building block 3 is sleeved with the positioning guide rail 6 through the first positioning slide rail grooves 7, thereby positioning the building block 3.

[0039] Specifically, as Figure 3 shown, a first clearance groove 8 is opened at one corner inside the building block 3 close to the notch 4, and a first outer chamfer 9 is opened at the top end of one corner inside the building block 3 close to the notch 4; the first outer chamfer 9 is slidably fitted with the inner chamfer 5, which facilitates the insertion of the building block 3 and at the same time increases the contact area between the building block 3 and the notch 4, further ensuring the stability of the building block 3.

[0040] Specifically, as Figure 2 、 Figure 3As shown, a first positioning buckle 10 is fixedly connected to the inner top wall of the first clearance groove 8 below the first outer chamfer 9; the building block 3 can be limited in the notch 4 through the first positioning buckle 10.

[0041] Specifically, as Figure 1 and Figure 3 shown, the cross-section of the first positioning buckle 10 is L-shaped, the vertical end of the first positioning buckle 10 is flush with the first outer chamfer 9, a slope is provided at the lower end of the horizontal end of the first positioning buckle 10 on the side far from its vertical end, the first positioning buckle 10 is engaged with the inner chamfer 5, and the upper surface of the horizontal end of the first positioning buckle 10 is in contact with the lower surface of the outer frame 1; when the building block 3 is matched with the notch 4, the slope of the horizontal end of the first positioning buckle 10 is squeezed against the top of the inner chamfer 5, causing the first positioning buckle 10 to deform, so that the horizontal end of the first positioning buckle 10 drives its vertical end to deflect into the first clearance groove 8 until the horizontal end of the first positioning buckle 10 passes through the inner chamfer 5. Under the reset action of the first positioning buckle 10, its horizontal end and vertical end are respectively in contact with the lower surface of the outer frame 1 and the inner wall of the inner chamfer 5, thereby limiting the building block 3 in the notch 4.

[0042] Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that, as Figure 4 and Figure 7 shown, under the connection of the building block link 11, multiple outer frames 1 can be assembled into different shapes, and two or more outer frames 1 can be assembled into various shapes such as a straight shape, an L shape, and a square shape;

[0044] Specifically, as Figure 4 and Figure 6 shown, it further includes a building block link 11. The building block link 11 is slidably fitted in the notch 4 between two outer frames 1. The length of the building block link 11 is equal to the sum of the lengths of two building blocks 3. Both ends of the building block link 11 are adapted to the notch 4; when multiple outer frames 1 are assembled, the building blocks 3 and the building block link 11 can be engaged with the corresponding notches 4, and the adjacent two outer frames 1 can be connected under the action of the building block link 11.

[0045] Specifically, as Figure 6 shown, second positioning slide rail grooves 12 adapted to the positioning guide rails 6 are provided in the middle of the lower ends on both sides of the building block link 11. The second positioning slide rail grooves 12 are slidably fitted on the outside of the positioning guide rails 6. A second clearance groove 13 is provided on the side of the building block link 11 close to the inner wall of the notch 4. Second outer chamfers 14 are provided on both ends of the building block link 11 close to the inner chamfer 5. The second outer chamfers 14 are in sliding fit with the inner chamfer 5; the second positioning slide rail grooves 12 on both sides of the building block link 11 are corresponding to the notches 4 on two adjacent outer frames 1 and are inserted, so that the two outer frames 1 can form an integral body.

[0046] Specifically, as Figures 4-6 shown, a second positioning buckle 15 is fixedly connected to the middle of the inner top wall of the second clearance groove 13. The cross-section of the second positioning buckle 15 is L-shaped. The vertical end of the second positioning buckle 15 is flush with the outer surface of the building block connecting block 11. A slope is provided at the lower end of the horizontal end of the second positioning buckle 15 and away from its vertical end. The second positioning buckle 15 is engaged at the intersection of the two outer frames 1. The upper surface of the horizontal end of the second positioning buckle 15 contacts the lower surface at the intersection of the two outer frames 1. Through the slope on the second positioning buckle 15 contacting and pressing against the tops of two adjacent outer frames 1, the horizontal end and the vertical end of the second positioning buckle 15 are deformed and deflected into the second clearance groove 13. When the horizontal end of the second positioning buckle 15 passes through the intersection of the two outer frames 1, under the reset of the second positioning buckle 15, its horizontal end and vertical end can respectively contact the lower surface at the intersection of the two outer frames 1 and the inner wall of the notch 4, so as to limit the two adjacent outer frames 1 by the building block connecting block 11.

[0047] In summary, compared with the prior art, the building block fan has at least the following beneficial effects: The present invention can arrange the outer frame 1 into the required shape according to needs, and then select appropriate building blocks 3 and building block connecting blocks 11 according to the positions of the notches 4 of two adjacent or multiple outer frames 1, and fit the appropriate building blocks 3 and building block connecting blocks 11 into a single notch 4 or two notches 4. With the cooperation of the notch 4, the positioning guide rail 6, the inner chamfer 5, the first positioning buckle 10 and the second positioning buckle 15, the building blocks 3 and the building block connecting blocks 11 can be engaged in the notch 4, so that the shape of the outer frame 1 is fixed. In this way, not only the assembly is flexible, but also the applicable range of the building block fan is expanded.

[0048] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
