Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure gauges, in particular to a tire pressure gauge which is convenient for detection. Background Art

[0002] A tire pressure gauge is a tool for measuring the tire pressure of a vehicle. There are three types of tire pressure gauges: pen-type tire pressure gauges, mechanical pointer tire pressure gauges, and electronic digital tire pressure gauges. Among them, the digital tire pressure gauge is the most accurate and convenient to use. Air pressure is the lifeblood of a tire. Too high or too low pressure will shorten its service life.

[0003] At present, most of the tire pressure gauges are equipped with a sealing plate on the detection valve so that the user can close the detection valve through the sealing plate after use. The sealing plate prevents external dust and mud from entering the detection valve, which may affect the detection accuracy of the tire pressure gauge. For example, a tire pressure gauge that is easy to detect is disclosed in Chinese patent publication No. CN218524285U. However, before and after each use, the user needs to manually open and close the sealing plate, which makes the tire pressure gauge more troublesome to use. At the same time, the deflation head is exposed to the outside of the tire pressure gauge, which makes it easy to be damaged. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: at present, most of the tire pressure gauges are provided with a sealing plate on the detection air nozzle, so that the user can close the detection air nozzle through the sealing plate after use, and the sealing plate prevents external dust and soil from entering the detection air nozzle, which affects the detection accuracy of the tire pressure gauge. However, before and after each use, the user needs to manually open and close the sealing plate, which makes the tire pressure gauge more troublesome to use. At the same time, since the deflation head is exposed to the outside of the tire pressure gauge, the deflation head is easily damaged. Therefore, a tire pressure gauge that is easy to detect is proposed.
