Technical Field
[0001] The utility model belongs to the field of solar cells, in particular to a solar cell frame fixing structure. Background Art
[0002] The connection of the frame of the existing solar cell assembly is usually connected into a frame (square frame) by inserting angle brackets at the two ends of the four frames. The angle brackets are provided with barbs, and the frame is provided with a square cavity, and the square cavity is provided with a bayonet. When the angle bracket is inserted into the square cavity of the frame, the barbs on the angle brackets are just caught on the bayonet, so that the frame profile is connected to the frame through the angle brackets to fix the frame. However, this fixing method has the following problems: first, a bayonet is required in the square cavity of the frame, so the processing technology is complicated and the processing cost is high. Second, when the concave-convex between the bayonet in the frame and the angle bracket barb are matched, the matching dimensional accuracy between the bayonet and the barb is high. If the dimensional accuracy is not enough, it is easy to cause hidden dangers such as the snap-fit (matching) is not in place or the concave-convex is not locked, resulting in a loose fixing. Summary of the invention
[0003] The utility model aims to provide a solar cell frame fixing structure.
[0004] The utility model aims to solve the problems that the existing solar panel frame processing technology is complicated and the processing cost is high, and the snap-in in the frame is easy to produce misalignment or the concave and convex are not locked when snapping with the corner code, resulting in loose fixing.
[0005] The technical scheme adopted by the utility model is: a solar cell frame fixing structure, comprising a frame and an angle code, the frame is a square tube structure, a square cavity is arranged in the square tube structure, the angle code is a right-angled angle code, the angle code has two right-angled sides, a row of inwardly inclined bevel teeth are arranged on the inner side of each right-angled side, the thickness D of the right-angled side is greater than the inner width of the square cavity, and a layer of pressure-sensitive adhesive is arranged in the square cavity; when the two right-angled sides of the angle code are respectively inserted into the square cavities of the two frames, the outer sides of the right-angled sides are clamped on the outer wall of the square cavity, and the bevel teeth on the right-angled sides are clamped on the pressure-sensitive adhesive on the inner wall of the square cavity.
[0006] A row of oblique teeth on the right-angled side has at least two teeth, and the row of oblique teeth are parallel to each other and arranged at intervals.

[0010] Preferably, the pressure-sensitive adhesive is a hot-melt pressure-sensitive adhesive, a photosensitive pressure-sensitive adhesive, or a water-based pressure-sensitive adhesive.
[0011] The beneficial effect of the utility model is that when the frame of the utility model is fixed by the corner code into a frame (a square frame), as long as the corner code is directly inserted into the square cavity of the frame, the oblique teeth (inverted teeth) of the corner code are clamped on the pressure-sensitive adhesive in the square cavity of the frame, and the required tensile resistance is generated. At this time, the frames are connected to each other through the corner code and are firmly fixed to each other. Compared with the existing frame with a bayonet, firstly, the frame of the utility model does not need to be provided with a bayonet, so the processing technology is simple and the production cost is low; secondly, there is no matching size accuracy requirement between the frame of the utility model and the corner code; thirdly, the diagonal quality of the frame is improved.
