[0023] The following further elaborates on the present utility model based on the attached drawings and embodiments.

[0024] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0025] This embodiment provides a landscape windmill, which includes a support frame 1, a support shaft 2 installed on the support frame 1, and a windmill mechanism 3 arranged on the support shaft 2 and rotatably matched with the support shaft 2. The support frame 1 includes a plurality of connecting frames 11 sequentially connected along the height direction of the support frame 1. At least one connecting mechanism 4 is arranged between two adjacent connecting frames 11. The connecting mechanism 4 and the two adjacent connecting frames 11 are both detachably connected. For example, it can be connected by bolts. That is, the support frame 1 can be disassembled into a plurality of connecting frames 11 through the connecting mechanism 4. On the one hand, when transporting the windmill, the support frame 1 can be disassembled through the connecting mechanism 4, thereby effectively reducing the size and weight of the windmill, making the transportation process simpler and more efficient, and helping to reduce the transportation cost. On the other hand, by selectively disassembling and assembling the connecting frames 11, the overall height of the windmill can be controlled, enabling the windmill to be more conveniently integrated into the surrounding landscape environment and achieving a better overall landscape effect.

[0026] Furthermore, the connecting frame 11 includes four erected vertical poles 11a. A decorative plate 11b is connected between two adjacent vertical poles 11a. The decorative plate 11b is arranged horizontally, and the decorative plate 11b and the vertical pole 11a are detachably fixed. This enables the connecting frame 11 to be disassembled when transporting the windmill, facilitating the transportation of the windmill. When fixing between the connecting frames 11, since the structures of two adjacent connecting frames 11 are the same, only one connecting frame 11 needs to be placed on top of the other connecting frame 11, aligning the corresponding vertical poles 11a on the two connecting frames 11. One end of the connecting mechanism 4 is connected to two adjacent vertical poles 11a of one connecting frame 11, and the other end is connected to two adjacent vertical poles 11a of the other connecting frame 11, thereby realizing the fixation of two adjacent connecting frames 11.

[0027] Specifically, the connecting mechanism 4 includes two oppositely arranged mounting plates 41, which are respectively fixed on two adjacent vertical rods 11a of the connecting frame 11. A plurality of connecting members 42 are connected between the mounting plates 41, and the size of the connecting members 42 is set to be the same as that of the decorative plate 11b, making the appearance of the landscape windmill more coordinated and unified with good visual effects. At the same time, arranging the connecting members 42 between the mounting plates 41 can also improve the structural strength of the connecting frame 11.

[0028] Since the landscape windmill is mainly used for outdoor decoration, its appearance and aesthetic sense are crucial. That is, the connecting members 42 are set to be three, and the three connecting members 42 are respectively connected to the middle, bottom, and top of the mounting plate 41, with better visual effects. At the same time, the width of the mounting plate 41 is set to be the same as the width of the vertical rod 11a. The same width of the mounting plate 41 and the vertical rod 11a not only facilitates fixing the mounting plate 41 on the vertical rod 11a but also makes the appearance of the landscape windmill more coordinated and unified, avoiding the visual disharmony caused by different widths of the mounting plate 41 and the vertical rod 11a.

[0029] In this embodiment, the windmill mechanism 3 includes a cross mounting frame 31 and a blade assembly 32. The cross mounting frame 31 has four outwardly extending portions, and a blade assembly 32 is fixed on each portion. A central through hole 31a for the support shaft 2 to pass through is provided in the central portion of the cross mounting frame 31. When the wind drives the blade assembly 32 to drive the cross mounting frame 31 to rotate, the central through hole 31a is the rotation center of the windmill mechanism 3. The windmill mechanism 3 rotates as a whole around the support shaft 2, and at the same time, the windmill mechanism 3 is hung on the support shaft 2 as a whole. The support shaft 2 passes through the central through hole 31a and is rotationally matched with the windmill mechanism. At the same time, two spaced-apart limit members 5 are provided on the support shaft 2, and the cross mounting frame 31 is arranged between the two limit members 5. The limit members 5 can be abutted against the two side surfaces of the cross mounting frame 31, thereby realizing the position limitation of the cross mounting frame 31, ensuring the stability of the cross mounting frame 31 during rotation, and the limit members 5 are detachably connected to the support shaft 2.

[0030] Preferably, the limit member 5 is set as a nut, and the support shaft 2 is provided with a thread for the nut to cooperate with, which can facilitate the removal of the windmill mechanism 3 from the support shaft 2 and can control the tightness of the nut against the cross mounting frame 31 through the screwing depth of the nut, thereby playing a role in adjusting the rotation speed of the blade assembly 32.

[0031] Since a landscape windmill of the present utility model is generally used outdoors, when the wind force outdoors is relatively large, it is easy to cause the rotation speed of the windmill to be too fast, which may lead to fatigue damage and aging of various components of the windmill, thereby shortening the overall service life of the windmill. In order to improve the service life of the windmill, in this embodiment, it is preferably that the blade assembly 32 includes a plurality of blades 32a fixedly arranged on the cross support frame 31 at intervals. A ventilation space is formed between two adjacent blades 32a. When the wind force is large, the wind passes through the ventilation space, so that the wind force received by the blade assembly 32 is weakened, thereby avoiding high rotation speed of the windmill mechanism 3 and contributing to improving the service life of the windmill.

[0032] Furthermore, the connection between the blade 32a and the cross support frame 1 is detachable. On the one hand, by selectively disassembling and assembling the blade 32a, the size of the ventilation space can be controlled, thereby realizing the adjustment of the rotation speed of the windmill device. On the other hand, by disassembling the blade 32a, the size of the windmill mechanism 3 can be reduced, which is convenient for packaging and transporting the windmill.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present utility model.
