Pressure gauge detection device

The pressure gauge detection device comprises a machine shell, a detection cavity communicated with the outside is arranged in the machine shell, a transmission mechanism, a display mechanism and a classification mechanism are arranged in the machine shell, the classification mechanism can classify inspected articles, the transmission mechanism can convey the articles, and the display mechanism comprises a buffer mechanism capable of circularly detecting the articles. The pressure of an object is judged by converting the pressure of the object into the volume of the solution pushed out of the water tank by the object, and the solution in the water tank has a buffering effect, so that insufficient measurement accuracy caused by direct falling of the object is prevented; the magnetism of the designed electromagnet is controlled through the current of the electromagnet, so that the device can convert objects with different checked masses into currents with different magnitudes, the position of a telescopic rod i
