Description

A tire pressure tester with illumination

[Technical Field]

The present invention relates to the field of testers and, more particularly, to a tire pressure tester with illumination.

【Background technique】

The air pressure in the tires of motor vehicles has a great influence on the driving performance and safety of the vehicle. If the pressure is too high, the tire and the ground base area become smaller, and the adhesion is reduced. Especially in the case of emergency braking, the danger is likely to occur, and the air pressure is too low. Increases fuel consumption and reduces tire life. In order to ensure the stability and safety of the driving performance of the motor vehicle, it is often necessary to check the tire air pressure. The usual inspection method is to beat the tire with a stick or kick the tire to feel the gas pressure in the tire. This inspection method is subjective and prone to occur. Misjudgment, judgment is not accurate enough.

For some more professional units or personnel, the tire is measured by a large, heavy, and difficult to carry tire pressure gauge. This inspection method is accurate. However, since it is not easy to carry, it is inconvenient in actual use. The Chinese Patent Publication No. CN2531960Y discloses a tire manometer having a front outer casing 1 having a tip end, a vent hole 8 beside the top end, and a piston 2 and a piston in the outer casing. There is a piston sealing ring 6 with a scaled gauge 3 at the top end of the piston, a spring 4 between the piston and the rear cover 5, and a valve sealing ring 7 at the front end of the outer casing. When in use, align the tip of the inner mouth of the casing with the valve of the tire to be tested, press the valve with the top, and the gas in the tire enters the casing through the vent hole beside the tip, jack up the piston, compress the spring, and push the watch out of the casing, read The scale on the scale is the gas pressure inside the tire, so that the driver can take appropriate measures against the air pressure of the tire to ensure the driving needs. The tire manometer is small in size, light in weight and easy to carry.

It can be used directly by the tire manometer when it is necessary to measure the tire during the day. However, at night, it is necessary to measure the tire through the tire manometer under the light. If there is no extra light at night, it is inconvenient to measure the tire.
