Please refer to the fifth figure. The transparent plate 3 of the present invention also has a correction unit 33, 34. The correction unit 33, 34 can be a cross sign or other graphic marks, which allows the user to adjust the accuracy. The correction units 33, 34 are printed on the inner surface 31 and the outer surface 32 of the transparent plate 3 at the same time, so that the correction units 33, 34 can be used for the height difference and oblique view of the inner surface 31 and the outer surface 32 of the transparent plate 3 The angular misalignment achieves the principle that the reading line of sight is perpendicular to the printing surface of the dial 310, that is, the pressure value of the pressure gauge 2 can be read by using the cross marks printed on the inner surface 31 and the outer surface 32 of the transparent plate 3 to overlap. Or the pressure value of the pressure gauge 2 can be accurately read when the automatic equipment is operating.

The transparent plate 3 can be printed on the front and back, and the front surface of the outer surface 32 of the transparent plate 3 can be printed with operation warnings or shop logos.

Please refer to the eighth to tenth figures, the inner surface 31 of the transparent plate 3 with the pressure dial 310 is integrally formed with the cylindrical body 21 to form a pressure gauge 2.

In summary, this creation provides an improvement to the display structure of the pressure gauge 2 of the air compressor 13, especially a transparent plate 3 that can be printed on the front and back, so that the pressure dial 310 is marked on the transparent plate 3 Facing the inner surface 31 of the pressure gauge 2, it is not easy for the user to touch, clean, or be contaminated by the outside environment to make it blurry and difficult to identify. The transparent flat plate 3 with pressure value and the cylindrical body 21 The pressure gauge 2 is integrally formed or combined separately. The transparent plate 3 also has a calibration unit 33, 34 that allows users to make accurate adjustments, so that the pressure of the pressure gauge 2 can be accurately read during manual operations or automatic equipment operations. Not only is the structure and design of this creation different from the existing conventional products, but it can also more accurately see the measured pressure value, which is quite practical. This creation is obviously novel and progressive, and it is a patent application.
