Magnesium alloy frame of photovohaics module

The utility model relates to a frame of a photovohaics module and particularly relates to a magnesium alloy frame of a photovohaics module, which solves the problem that Due to the adoption of the magnesium alloy frame, the problem that a photovohaics module is overlarge in entire weight and overhigh in long-distance transportation cost due to the overlarge weight of the frame of the photovohaics module can be solved. The magnesium alloy frame of the photovohaics module comprises four side frames and the cross sections of the four side frames are consistent in shape. The four side frames are connected end to end, wherein every two adjacent frames are mutually vertical and an L-shaped right-angle plate is connected between every two adjacent frames. The inner side surfaces of the two ends of each L-shaped right-angle plate are provided with a row of engagement teeth respectively. The two ends of each L-shaped right-angle plate are respectively connected with one ends of adjacent frames through two rows of engagement teeth. Both the frames and the L-shaped right-angle plate are made of magnesium alloy. The magnesium alloy frame is used for fixing and supporting photovohaics modules.
