Abstract:
1. A two-in-one temperature and pressure gauge comprising a shell, a housing, a score panel, a needle set, a temperature sensing mechanism, and a pressure sensing mechanism, wherein, upon assembling, the needle set is installed on a front of the score panel and is connected with the temperature sensing mechanism and the pressure sensing mechanism located at a rear side of the score panel, for rotation; after that, the aforementioned assembly being put into the shell for fixing, and allowing an outer tube of the temperature sensing mechanism and a tube connector of the pressure sensing mechanism to be exposed out of the shell; finally, the housing being covered on a front of the shell; the temperature sensing mechanism being assembled into the pressure sensing mechanism, allowing a rotation shaft of the temperature sensing mechanism and a rotation shaft of the pressure sensing mechanism to be installed coaxially; the needle set including two coaxially installed needles, with one needle being connected with the rotation shaft of the temperature sensing mechanism, and the other needle being connected with the rotation shaft of the pressure sensing mechanism.
