Load testing machine applied to photovoltaic system assembly

The invention relates to the technical field of photovoltaic module load testing, in particular to a photovoltaic system module load testing machine which comprises a main machine body, an internal operation cavity with an operation opening in one side is formed in the main machine body, and an embedded arc-shaped guide rail is fixedly installed in the internal operation cavity. And an arc-shaped adjusting seat is assembled in the embedded arc-shaped guide rail in a sliding manner. According to the load testing machine applied to the photovoltaic system assembly, a traditional overhead air cylinder is divided into a fixed type structure and a movable type structure, free switching can be achieved according to needs, and the operability of the testing machine is greatly improved; by adopting the design of the embedded arc-shaped guide rail, the position of the arc-shaped adjusting seat can be adjusted, and the guidance quality and the stability are greatly improved; and the top movable load supporting rod is f
