Safe float-type differential pressure gauge structure

The invention discloses a safe float-type differential pressure gauge structure. One end of a U-shaped tube is connected with a high-pressure chamber and the other end of the U-shaped tube is connected with a low-pressure chamber. The high-pressure chamber and the low-pressure chamber are both provided with a pressure introduction pipeline. Two pressure introduction pipelines communicate with each other via a pressure balance pipeline. A float is placed in the high-pressure chamber and is hinged to a connecting rod. The sidewall of the high-pressure chamber is provided with a rotating shaft. One end of the rotating shaft is located in the high-pressure chamber and hinged to the connecting rod. The other end of the rotating shaft is located outside the high-pressure chamber. The end, outside the high-pressure chamber, of the rotating shaft is connected with a touch pen. A touch panel is disposed on a side, far from the rotating shaft, of the touch pen. The U-shaped tube, the high-pressure chamber and the low-p
