Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-5 The present invention provides a technical solution: a foldable photovoltaic buckle, including two first connecting blocks 1, which are parallel and spaced apart, and a first connecting block 1 is provided between the two first connecting blocks 1; the first connecting blocks 1 and the second connecting block 2 are respectively fixedly connected to two adjacent photovoltaic panels; it also includes a plug-in component 3, on which the first connecting blocks 1 and the second connecting block 2 are movably disposed, so that the first connecting blocks 1 and the second connecting block 2 can rotate.

[0026] The first connecting block 1 includes a first main body 101, on which a first connecting part 102 is provided. The first connecting part 102 is used to fix to the outer frame of the photovoltaic panel. Specifically, the outer frame of the photovoltaic panel is provided with a groove that matches the first connecting part 102, and the first connecting part 102 is fixed in the groove. The first main body 101 also has a first abutting end 103, which is used to abut against the outer frame of the photovoltaic panel connected to the second connecting block 2.

[0027] The second connecting block 2 includes a second main body 201, on which a second connecting part 202 is provided, and a second abutting end 203 is provided on the second main body 201. The second connecting part 202 is used to fix to the outer frame of the photovoltaic panel. Similarly, the outer frame of the photovoltaic panel connected to the second connecting block 2 is provided with a groove that matches the second connecting part 202, and the second connecting part 202 is fixed in the groove. The first abutting end 103 is used to abut against the outer frame of the photovoltaic panel connected to the first connecting block 1.

[0028] The plug-in assembly 3 includes a plug-in screw 301, which passes through the first connecting block 1 and the second connecting block 2. Specifically, a first through hole 104 is provided through the first main body 101, and a second through hole 204 is provided through the second main body 201. The plug-in screw 301 passes through the first through hole 104 and the second through hole 204. The portion of the plug-in screw 301 that mates with the first through hole 104 and the second through hole 204 is not threaded, that is, the unthreaded portion of the plug-in screw 301 is compatible with both the first through hole and the second through hole 204.

[0029] The plug-in assembly 3 also includes a nut 302, which is threadedly connected to the plug-in screw 301. Two flat washers 303 are also fitted on the outside of the plug-in screw 301. The two flat washers 303 are respectively used to contact the non-adjacent ends of the two second main bodies 201. That is, by tightening the nut 302, the two sides of one of the flat washers 303 abut against the head of the plug-in screw 301 and the outside of one of the first main bodies 101, and the two ends of the other flat washer 303 abut against the other main body and the nut 302, thus fixing the plug-in screw 301. Since the plug-in screw 301 is adapted to the first through hole 104 and the second through hole 204, the first connecting block 1 and the second connecting block 2 can rotate at this time.

[0030] like Figure 5 As shown, multiple foldable photovoltaic clips can be installed between two adjacent photovoltaic panels, and the specific spacing can be arranged according to the length of the photovoltaic panel or actual needs.

[0031] In this embodiment, when the first connecting block 1 and the second connecting block 2 are respectively connected to the photovoltaic panel, and the first connecting block 1 and the second connecting block 2 are engaged with the plug-in component 3, the two adjacent photovoltaic panels can be folded, which facilitates the storage of the photovoltaic panels. When it is necessary to unfold the photovoltaic panel, the photovoltaic panel is mounted on the external linear guide rail, so that the photovoltaic panel can move along the guide rail. By applying a pulling force to the photovoltaic panel, the two adjacent photovoltaic panels can be unfolded under the action of gravity. When the first contact end 103 and the second contact end 203 respectively contact the two photovoltaic panels, the photovoltaic panel will no longer unfold. That is, there is no need to fix the photovoltaic panel. The unfolding tilt angle of the photovoltaic panel can be fixed by relying on the gravity of the photovoltaic panel.

[0032] Example 2

[0033] Please see Figures 1-6 This embodiment is based on Embodiment 1, with the first connecting block 1 and the second connecting block 2 having the same structure; when the first connecting block 1 and the second connecting block 2 have the same structure, and when the first contact end 103 and the second contact end 203 respectively contact the two photovoltaic panels, that is, as Figure 6As shown, this ensures that the acute angle between two adjacent photovoltaic panels and the horizontal direction remains consistent; that is, based on the differences in latitude, climate and solar radiation conditions in different regions, the structural shapes of the first connecting block 1 and the second connecting block 2 are reasonably set so that the tilt angle of the photovoltaic panels meets the optimal tilt angle selection for different regions.

[0034] Example 3

[0035] See again Figures 1-4 Based on Embodiment 2, this embodiment further includes a spring washer 304 in the plug-in assembly 3. The spring washer 304 is sleeved on the outside of the plug-in screw 301 and is used to be positioned between the nut 302 and the flat washer 303 adjacent to the nut 302. At this time, the nut 302 abuts against the spring washer 304, and the spring washer 304 abuts against the flat washer 303 adjacent to the nut 302. In this embodiment, by adding the spring washer 304, it is helpful to reduce the loosening of the nut 302 after long-term use.
