Clamping structure of photovoltaic panel

The utility model relates to the technical field of photovoltaic panels, in particular to a clamping structure of a photovoltaic panel, which comprises a first photovoltaic panel frame and a second photovoltaic panel frame, the opposite sides of the first photovoltaic panel frame and the second photovoltaic panel frame are fixedly connected with connecting blocks which abut against each other, a clamping groove is formed in the right end face of the connecting block on the left side, and a clamping groove is formed in the right end face of the connecting block on the right side. A clamping block clamped with the interior of the clamping groove is fixedly connected to the left end face of the connecting block located on the right side, a mounting hole is formed in the upper end face of the clamping block, and a compression spring is fixedly connected to the lower end of the interior of the mounting hole. And a compression spring has elastic potential energy, so that a sliding disc drives a limiting column to s
