Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of instruments and meters, in particular to a pressure value observation structure for a pressure gauge. Background Art
[0002] When the pressure gauge is working, the pressure value is read by the pointer set in the pressure gauge. Generally speaking, when measuring whether the pressure value of a device is within the preset range, it is necessary to carefully look at the position where the pointer points. Since many small pressure gauges have small dials and pointers, people need to be very careful to accurately see the pressure value. If you are not careful, it will cause errors in the reading, especially in places with strict pressure requirements, which can easily cause safety hazards.
[0003] When in use, existing factories generally mark the indication area on the dial with markers of different colors. After the pressure gauge is used for a long time and is subjected to vibration, the dial is easy to rotate on the pressure gauge, the indication area is easy to shift, and the color marked by the marker is easy to fade due to long-term exposure to wind, sun and rain, which can easily cause dangerous readings and cause safety hazards.
