Rainproof gauge pressure measuring device

The utility model belongs to the field of instruments and meters, and particularly relates to a rainproof gauge pressure measuring device. Comprising a shell, a pressure measuring sensitive body, a sealing ring, an air guide hole, a water inlet-drainage hole, a connector, a circuit board cavity and a water inlet-drainage cavity, one end of the connector is a mouthpiece, and the other end of the connector is of a cylindrical structure with an annular groove formed in the outer side; the inner end face of the annular groove and the inner wall of the shell are sealed through a sealing ring, and the outer end face of the annular groove is welded to the lower end of the shell. At least three water inlet-outlet holes are formed in the end surface of the outer side of the annular groove; an air guide hole is formed in the end face of the inner side of the annular groove, the air guide hole and the water inlet-drainage hole are located in the same radial direction, and the air guide hole is closer to the central axis
