Tire pressure calibration device for vehicle tire inflator pump

A tire pressure calibration device for a vehicle tire inflator pump comprises an electric air pump, an air gun high-pressure hose, an air gun, an air gun pressure gauge and an electronic calibration device, the electric air pump is communicated with the air gun through the air gun high-pressure hose, the air gun pressure gauge is arranged on the air gun, and the output end of the air gun is communicated with an inflation nozzle through a three-way connector and a high-pressure inflation nozzle hose. The electronic calibration device is arranged on one side of the air gun; the electronic calibration device comprises a first air pressure sensor, a second air pressure sensor, a 51 single-chip microcomputer and an electronic digital display screen. Wherein the first air pressure sensor is communicated with the three-way connector through a first high-pressure two-way hose, the second air pressure sensor is communicated with the charging connector through a second high-pressure two-way hose, and the air pressure s
