Abrégé

A connection structure of a diaphragm pressure gauge contains: a holder, a coupling sleeve, a disc, a curved abutting bar, a fixing element, a case, a screw element, a circular film, and a defining element. The holder is connected to the coupling sleeve, multiple spaced ribs of the holder extend out of the coupling sleeve, and the holder includes the multiple spaced ribs. One of the multiple spaced ribs has at least one spaced protrusion, the disc includes at least one first locating orifice, the curved abutting bar includes a second locating orifice, and the at least one first locating orifice is fitted with the second locating orifice. The curved abutting bar abuts against the fixing element, and the defining element, the circular film and the screw element are connected below the fixing element to produce the diaphragm pressure gauge. The case is covered on the diaphragm pressure gauge.

A pressure gauge structure contains: a body having a bow-shaped frame and a holder mounted under the bow-shaped frame, and a contact film defined between the bow-shaped frame and the holder. A connector is connected on a bottom of the holder, and a test conduit passes through the holder and the connector and accommodates a tested object. The contact film contacts with a separation washer corresponding to the contact film.

A tire pressure gauge contains a housing, a pressure measuring unit, and a tire-tread depth measuring unit. The tire-tread depth measuring unit includes a mounting assembly, a gear assembly, a hair spring, a covering lid, and a longitudinal post. The tire pressure gauge measures a tire pressure and a tire-tread depth. The tire-tread depth measuring unit indicates a number of the tire-tread depth by using a pointer, after a measurement stem of the longitudinal post is inserted into a tread slit of a tire, and a longitudinal movement of the longitudinal post is transformed into circumference rotation data through the gear assembly, thus indicating the number of the tire-tread depth on a numerical display panel clearly. Preferably, a probe and the measurement stem of the longitudinal post inserted into the tread slit are driven by the hair spring to return to a zero state.
