[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-6 The present invention provides a technical solution: a multi-angle adjustable buckle for foldable photovoltaics, including a first support 1 and a second support 2 that are hinged to each other. Specifically, the first support 1 and the second support 2 are hinged together by a hinge shaft. The first support 1 and the second support 2 can rotate around the hinge shaft. A protruding part for limiting the first support 1 and the second support 2 is provided in the middle of the hinge shaft. Ring-shaped structural members for limiting the first support 1 and the second support 2 are fixedly sleeved at both ends of the hinge shaft. The above are all prior art and will not be described in detail here.

[0028] The first support 1 and the second support 2 are used to connect two adjacent photovoltaic panel modules, respectively. Specifically, the first support 1 and the second support 2 are connected to the frame of the photovoltaic panel module, and respectively to the adjacent ends of the two frames; the first support 1 and the second support 2 have the same structure, are installed in opposite directions, and are spaced apart, i.e. Figure 2 As shown; since the first support 1 and the second support 2 are rotatable, adjacent photovoltaic panels can be folded or unfolded.

[0029] It also includes two limiting members 3, one of which corresponds to the first support 1 and the other of which corresponds to the second support 2. The limiting member 3 corresponding to the first support 1 is used to limit the unfolding of the photovoltaic panel module connected to the second support 2, while the limiting member 3 corresponding to the second support 2 is used to limit the unfolding of the photovoltaic panel module connected to the first support 1.

[0030] The first support 1 is provided with a first adjustment component 4, and the angle of the limiting member 3 corresponding to the first support 1 is adjusted and fixed by the first adjustment component 4. The second support 2 is provided with a second adjustment component 5, and the angle of the limiting member 3 corresponding to the second support 2 is adjusted and fixed by the second adjustment component 5.

[0031] The limiting component 3 includes a limiting post 31, and a plurality of arc-shaped limiting pieces 32 are sequentially sleeved on the outside of the limiting post 31. The outer ring surface of each arc-shaped limiting piece 32 is used to contact the photovoltaic panel module. Two adjacent arc-shaped pieces cooperate and are fixedly connected. The arc-shaped limiting pieces 32 adjacent to the limiting post 31 are fixedly connected to the limiting post 31. Each arc-shaped limiting piece 32 has a different size, that is, the inner ring surface and the outer ring surface are different. However, among two adjacent arc-shaped limiting pieces 32, the outer arc-shaped limiting piece 32 is fitted to the outside of the other arc-shaped limiting piece 32.

[0032] like Figure 3 As shown, each arc-shaped limiting piece 32 is coaxial with the limiting post 31. One end of each arc-shaped limiting piece 32 is aligned with the other end, and the other end is staggered. The overall length of the arc-shaped limiting piece 32 is smaller the closer it is to the outside. The difference in diameter of the outer ring surface of any two adjacent arc-shaped limiting pieces 32 (i.e., the absolute value of the difference) is equal, that is, the thickness of each arc-shaped limiting piece 32 is equal.

[0033] The axes of the two limiting posts 31 can be symmetrically arranged about the hinge axis; when the axes of the two limiting posts 31 are symmetrically arranged about the hinge axis, and the two limiting posts 31 respectively abut against the frame of the two photovoltaic panels, the two adjacent photovoltaic panels can be symmetrically arranged.

[0034] The first adjusting screw 41 is threadedly connected to the first support 1. The first adjusting screw 41 penetrates the center position of the corresponding limiting post 31 of the first support 1, and the first adjusting screw 41 is fixedly connected to the limiting post 31. Specifically, the first support 1 is provided with a threaded hole structure adapted to the first adjusting screw 41, and the center line of the first adjusting screw 41 is collinear with the axis of the limiting post 31. By rotating and adjusting the first adjusting screw 41, due to the threaded connection, the first adjusting screw 41 can be fixed on the first support 1 after adjustment, thereby realizing the adjustment and fixation of the angle of the entire limiting member 3. Although the position of the limiting member 3 changes, the center line of the first adjusting screw 41 is collinear with the axis of the limiting post 31. Therefore, different arc-shaped limiting pieces 32 can be adjusted to abut against the frame of the photovoltaic panel module.

[0035] The second adjusting screw 51 is threadedly connected to the second support 2. The second adjusting screw 51 penetrates the corresponding limiting post 31 of the second support 2 and is fixedly connected to the limiting post 31. Similarly, the second support 2 is provided with a threaded hole structure that matches the second adjusting screw 51. The center line of the second adjusting screw 51 is collinear with the axis of the limiting post 31. By rotating and adjusting the second adjusting screw 51, the angle of the limiting member 3 can be adjusted and fixed. Similarly, different arc-shaped limiting pieces 32 can be adjusted to abut against the frame of the photovoltaic panel module.

[0036] To facilitate adjustment of the arc-shaped limiting pieces 32 arranged in the same position on the two limiting pieces 3 to abut against the photovoltaic panel module frame, a notch 7 is provided at the same position on the first support 1 and the second support 2 (with the same structure). When the notch 7 completely corresponds to a certain arc-shaped limiting piece 32 and does not correspond to other arc-shaped limiting pieces 32, the arc-shaped limiting piece 32 corresponding to the notch 7 can limit the unfolding of the photovoltaic panel module, that is, when the outer photovoltaic panel module is unfolded, it abuts against the photovoltaic panel module frame. By adjusting the different arc-shaped limiting pieces 32 to correspond with the notch 7, the installation angle of the photovoltaic panel module can be adjusted and fixed.

[0037] By adjusting the first adjusting screw 41 and the second adjusting screw 51, different two arc-shaped limiting pieces 32 (of course, the two arc-shaped limiting pieces 32 are arc-shaped limiting pieces 32 arranged in the same position on the two limiting pieces 3) are adjusted to abut against the frame of the unfolded photovoltaic panel module, so as to realize the adjustment and fixation of the installation angle of the photovoltaic panel module, which can conveniently meet the installation needs of different regions. At the same time, while adjusting the unfolding angle of the photovoltaic panel module, it can also ensure that the acute angle between two adjacent installation angles, that is, between the photovoltaic panel module and the horizontal direction, is consistent. Of course, when unfolding the folded photovoltaic panel module, it is supported and guided by linear guide rails or support platforms to facilitate the unfolding of the photovoltaic panel module. When the limiting piece 3 abuts against the frame of the photovoltaic panel module, the installation angle of the photovoltaic panel module can be fixed.

[0038] Two or more of these snap-fit ​​structures can be set between two adjacent photovoltaic panel components. When one end of a photovoltaic panel component is connected to the first support 1, the other end of the photovoltaic panel component is connected to the second support 2, so as to ensure that each photovoltaic panel component can be folded.

[0039] Example 2

[0040] See again Figure 2 and Figure 5 Based on Embodiment 1, this embodiment provides a first mating part 11 on the first support 1. The first mating part 11 is used to fit on the frame of the photovoltaic panel assembly. Specifically, a slot structure adapted to the first mating part 11 is provided on the frame of the photovoltaic panel assembly to which it fits.

[0041] In addition, the first mating part 11 is provided with a connecting threaded hole 6, which facilitates the connection between the first mating part 11 and the first support 1 by bolts. That is, the bolts penetrate the frame of the photovoltaic panel and are threadedly connected in the connecting threaded hole 6, which facilitates the connection between the first support 1 and the photovoltaic panel.

[0042] Example 3

[0043] See again Figure 2 and Figure 6Based on Embodiment 2, this embodiment provides a second mating part 21 on the second support 2. The second mating part 21 is used to fit on the frame of the photovoltaic panel assembly. Specifically, a slot structure adapted to the second mating part 21 is provided on the frame of the photovoltaic panel assembly to which it is mated.

[0044] The second mating part 21 is provided with a connecting threaded hole 6, which facilitates the connection between the second mating part 21 and the second support 2 by bolts, thereby facilitating the connection between the second support 2 and the photovoltaic panel module.
