[0002] A fluid medium pressure gauge is an instrument used to measure the internal pressure of a fluid. For example, the current fluid medium refers to a method of converting energy using fluid as a working medium. A fluid medium pressure gauge measures the pressure value inside the fluid when the fluid converts energy.

[0003] After searching, the patent number "CN212133971U" discloses a fluid medium pressure gauge with an external dustproof mechanism, including a pressure gauge body, a bottom plate fixedly arranged outside the pressure gauge body, and a cavity opened inside the bottom plate. This solves the problem that the pressure gauge has no external dustproof structure and is easily contaminated with fixed particles when measuring the pressure of the fluid medium.

[0004] The above-mentioned pressure gauge achieves dustproof effect through the design of the protective cover, but the above-mentioned protective cover needs to be opened by hand-cranking through the crank, which is cumbersome to open. At the same time, after the protective cover is opened, it cannot be limited and fixed, which is inconvenient for reading the pressure gauge. For this reason, we designed a dustproof mechanism for the fluid medium pressure gauge. Summary of the invention
