Testing device for internal elastic structure of pressure cooker

A pressure cooker internal elastic structure testing device disclosed by the present invention comprises a rack and a pressurizing assembly capable of pressurizing the pressure cooker to simulate a high-pressure working state, the upper end of the rack is provided with an upper end opening for loading an inner pot of the pressure cooker, and the upper end of the rack is provided with a plurality of locking assemblies for locking the inner pot of the pressure cooker. A plurality of detection ends of the displacement measuring instrument are respectively connected with the position of a pressure cooker heating plate capable of penetrating through the bottom surface of the inner pot, and the displacement measuring instrument is used for detecting the downward displacement value of each detection point of the heating plate when the inner container of the pressure cooker is pressurized to push the heating plate to move downwards; a measuring instrument fixing assembly used for fixing the displacement measuring ins
