AI Technical Summary
When existing pressure gauges are used in underground pipelines, the light is evenly distributed on the dial, making it difficult to highlight the dial markings and thus making observation difficult.
A pressure gauge for underground pipelines has been designed. The dial has a raised platform at the center, with the scale lines protruding. The transparent part of the pointer is located on the raised platform. The inner peripheral wall of the dial has a reflective ring, and the scale lines are located between the reflective ring and the raised platform. The scale lines and the indicator are coated with a fluorescent coating, and the cover is coated with an anti-fog coating.

[0007] The utility model is further provided with: the pointer includes transparent part and indication part, the projection of the transparent part on the dial is located on the boss.
[0008] The utility model is further provided with: the inner peripheral wall of the dial is equipped with light ring, the scale line is located between the light ring and the convex strip, and the light line irradiated on the light ring can be reflected towards the scale line direction.
[0009] The utility model is further provided with: the side of the light ring towards the dial is attached with the dial, and the thickness of the light ring is smaller and closer to the center of the dial.
[0010] The utility model is further provided with: the scale line and indication part are all coated with fluorescent coating.
[0011] The utility model is further provided with: the dial is detachably connected with the watch cover, and the surface of the watch cover is coated with anti-fog coating.
[0012] In summary, the utility model has the following beneficial effects:
[0013] When people direct the light of the flashlight to the dial, the light on the convex post will be reflected, and the reflection direction is the reflection direction away from the center of the dial, so that part of the light that should be in the center of the dial is reflected to the position of the dial scale line, so that the position of the dial scale line is brighter, thereby highlighting the position of the dial scale line. This arrangement improves the brightness of the position of the scale line, thereby facilitating the observation of the data of the dial. BRIEF DESCRIPTION OF DRAWINGS
