Elastic strip buckling pressure testing machine

The utility model relates to an elastic strip buckling pressure testing machine which comprises a machine frame, a mounting seat used for fixedly mounting an elastic strip is arranged on the top surface of the machine frame, a hydraulic cylinder and a pressure sensor are sequentially arranged in the machine frame from bottom to top, a sliding ejector rod is vertically arranged above the pressure sensor, and the sliding ejector rod is connected with the hydraulic cylinder. The hydraulic cylinder extends to enable the top end of the sliding ejector rod to vertically move upwards to abut against the toe end of the elastic strip, the pressure sensor is used for measuring buckling pressure generated by deformation of the toe end of the elastic strip to the sliding ejector rod, a displacement sensor is vertically and fixedly arranged on the rack, and the sliding ejector rod is fixedly connected with a pull rod of the displacement sensor through a connecting rod. The displacement sensor is used for measuring the mov
