Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure measuring tools, in particular to a portable tire pressure gauge. Background Art

[0002] Air pressure is the lifeblood of tires and should not be too high or too low. When the air pressure is too low, the deformation of the tire body increases, cracks are likely to appear on the sidewalls, and flexion movement occurs, resulting in excessive heat generation, rubber aging, tire cord fatigue, and cord breakage. Too low air pressure will also increase the tire contact area and accelerate shoulder wear; when the air pressure is too high, the tire cord will be excessively stretched and deformed, the elasticity of the tire body will decrease, and the load on the car during driving will increase. If impacted, it will easily cause internal cracks and explosions. At the same time, too high air pressure will accelerate crown wear and reduce rolling resistance. Therefore, too high or too low air pressure will shorten the service life of the tire and affect the safety performance of the vehicle.

[0003] A tire pressure gauge is a tool for measuring the air pressure of automobile tires. It is often designed as an integrated unit with a tire inflator. It can accurately measure the air pressure of tires, provide technical support for monitoring tire pressure and tire inflation, effectively increase the service life of tires, and ensure the safe use performance of vehicles.
