Pressure testing machine for detecting polymer building materials

The invention discloses a pressure testing machine for detecting a polymer building material, and relates to the field of pressure tests.According to the pressure testing machine, the clamping direction of a plate is adjusted according to bending deformation of the edge of the plate by arranging a connecting rod and a rotating shaft, and it is guaranteed that the plate is clamped firmly; meanwhile, it is guaranteed that in the testing process of the plates, the clamping plates cannot damage the plates due to deformation of the plates, errors of the testing result are avoided, the accuracy of the measuring result is improved, the plate locking mechanism is arranged, the stability and reliability of clamping the plates are guaranteed, meanwhile, the result accuracy of the plates during testing is guaranteed, and the testing efficiency is improved. The test head can be controlled by the first-stage hydraulic rod to perform a pressure test on the central point of the material, and meanwhile, the height of the tes
