Pressure testing machine for concrete

The utility model relates to the technical field of concrete, and discloses a pressure testing machine for concrete, which comprises a supporting seat, an L-shaped plate is arranged at the top of the supporting seat, and a pressure component with one end penetrating and extending to the bottom of the L-shaped plate is arranged at the top of the L-shaped plate. According to the pressure testing machine for the concrete, a clamping plate is pulled to be separated from a limiting groove, then a rotating rod is rotated to enable a driving gear to drive a driven gear to rotate in an engaged mode, a bidirectional threaded rod rotates, a left threaded block and a right threaded block move relatively, a round rod slides in a moving plate, and then the moving plate is pushed to drive a rolling wheel to move downwards; the rollers move downwards to be in contact with the ground, the supporting seat is jacked up, the purpose that the pressure testing machine is convenient to move is achieved, a good damping function can
