[0039] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-13 An aluminum frame suitable for photovoltaic cells of different thicknesses includes a main frame 1, a length adjustment component 2, a locking component 3, and a splicing component 4;

[0040] The main frame 1 is connected to both the length adjustment component 2 and the splicing component 4. The length adjustment component 2 is connected to the splicing component 4. The locking component 3 is connected to both the main frame 1 and the length adjustment component 2.

[0041] The locking assembly 3 includes a height adjustment component, a first rubber strip 34 and a second rubber strip 35.

The second rubber strip 35 is internally slidably connected to the first rubber strip 34. The size adjustment component is connected to the main frame 1 and the length adjustment component 2.

[0042] The main frame 1 includes a first baffle 11, a second baffle 12, a third baffle 13, a fourth baffle 17, and a fifth baffle 18. The front side of the fifth baffle 18 is fixedly connected to the first baffle 11, the second baffle 12, and the third baffle 13. The first baffle 11, the second baffle 12, and the third baffle 13 are arranged sequentially from top to bottom. The first baffle 11 has multiple through holes 14 at equal intervals. The upper end of the fourth baffle 17 is fixedly connected to the second baffle 12, and the lower end of the fourth baffle 17 is fixedly connected to the third baffle 13. The connecting parts of the second baffle 12, the third baffle 13, and the fifth baffle 18 together form a receiving cavity 15. The left end of the third baffle 13 has a slot 16.

[0046] The fixing plate 235 is connected to the splicing component 4.

[0047] Effect: Pressing the buckle 22 by hand causes the buckle 22 to squeeze the elastic piece 21 into the upper moving frame 231, thus unlocking the upper moving frame 231 from the through hole 14. Moving the upper moving frame 231 to the appropriate position causes the buckle 22 to enter the through hole 14 under the elastic force of the elastic piece 21, locking the through hole 14 with the upper moving frame 231. This allows the photovoltaic frame to adapt to photovoltaic cells of different sizes or installation scenarios, improving the product's versatility and adaptability.

There are two sliding columns 32 and two first springs 33, which are located on the left and right sides of the bolt 31, respectively.

[0050] The second set of size adjustment components is installed and connected to the second rubber strip 35:

[0051] The second set of size adjustment components includes a bolt 31, a sliding column 32, and a first spring 33. The first spring 33 is sleeved on the outer end of the sliding column 32, and one end of the first spring 33 is fixedly connected to the top of the sliding column 32. The sliding column 32 is fixedly connected to the upper end of the second rubber strip 35. The bolt 31 is rotatably connected to the upper end of the second rubber strip 35. The sliding column 32 is slidably connected to the first moving plate 233. The bolt 31 is threadedly connected to the first moving plate 233. There are two of each of the sliding column 32 and the first spring 33, which are located on the left and right sides of the bolt 31, respectively.

[0052] Effect: When installing different photovoltaic cells, the bolt 31 adjusts the distance between the first spring 33, the first rubber strip 34 and the third baffle 13 according to the thickness of the photovoltaic cell. When the bolt 31 is turned, the bolt 31 moves and drives the first rubber strip 34 to move, thereby adjusting the distance between the first rubber strip 34 and the third baffle 13.

[0053] Similarly, the distance between the second rubber strip 35 and the second moving plate 234 is adjusted as described above;

[0054] This utility model adjusts the distance between the first rubber strip 34 and the third baffle 13 (and the distance between the second rubber strip 35 and the second movable plate 234) by tightening the bolt 31. This not only improves the adaptability of the photovoltaic frame to photovoltaic cells of different thicknesses, achieving precise positioning and buffer protection, and simplifying the installation process, but also enhances the stability of the photovoltaic cells after installation and effectively extends their service life.

[0055] The splicing component 4 includes a fixed frame 41, a second spring 43, a locking block 44 and a fixing block 46. The fixed frame 41 is fixedly installed on the left side of the front end of the fifth baffle 18. A slot 42 is opened in the middle of the fixed frame 41. The inside of the slot 42 is fixedly connected to one end of the second spring 43, and the other end of the second spring 43 is fixedly connected to the locking block 44.

[0056] The second spring 43 and the locking block 44 are provided in twos and are respectively located on the left and right sides inside the slot 42. The locking block 44 is respectively limited and slidably connected to the sliding grooves on the left and right sides inside the slot 42.

[0057] The splicing component 4 also includes a fixing block 46. A groove 45 is provided at the right end of the fixing plate 235. The fixing block 46 is fixedly installed inside the groove 45 and is engaged with two locking blocks 44.

[0058] The fixed block 46 has a rhomboid cross-sectional shape, and the locking block 44 has a trapezoidal cross-sectional shape.

[0059] Effect: The photovoltaic frame of this utility model is composed of four sets of photovoltaic frames connected end to end. When splicing, the fixing block 46 of the second set of photovoltaic frames is aligned with the slot 42 of the first set of photovoltaic frames. The second moving plate 234 is inserted into the slot 16, and the fixing block 46 is inserted into the slot 42. Due to the unique shape of the fixing block 46, the fixing block 46 contacts the two slots 44. The fixing block 46 presses the inclined ends of the two slots 44, causing the two slots 44 to move to both sides until the fixing block 46 is completely inserted into the interior of the two slots 44. Then, the two slots 44 lock the fixing block 46 under the action of the second spring 43. Then, the first set of photovoltaic frames and the second set of photovoltaic frames are fixed with screws.

[0060] To unlock the photovoltaic frame, remove the screws and pull the second set of photovoltaic frames outward so that the fixing block 46 contacts the two locking blocks 44. The fixing block 46 presses the inclined ends of the two locking blocks 44, causing the two locking blocks 44 to move to both sides until the fixing block 46 disengages from the two locking blocks 44. Then, the two locking blocks 44 reset under the action of the second spring 43, and the two photovoltaic frames are unlocked.

[0061] This utility model reduces the difficulty of installation and maintenance, improves work efficiency, and ensures the stability of the spliced ​​structure.
