There are many reasons for this, whether it is drunk driving, the driver’s mentality is not good, and the safety distance is not maintained. In recent years, the car has suffered from a puncture. As a result, traffic accidents have a clear upward trend. Therefore, in order to protect the safety of the car during driving, the tire pressure detection of the front tires of the automobile has become an important propaganda.

Therefore, the known tire pressure detecting structure, such as the "improved tire pressure measuring instrument" disclosed in the domestic patent application No. 83202058, includes: a housing base having a longitudinal axis along an inner side surface thereof An extended semi-circular channel, a ring edge is disposed at one of the open ends of the channel for forming a closed penetration hole, and a semicircular flange is disposed at the other open end of the channel, a battery receiving chamber Provided on one side of the channel, and at least one lamp holder extends from the periphery of the battery receiving chamber to the outer edge of the base; a conduit extends from the through hole into the channel with a rear end thereof and abuts The front edge portion is located in the semicircular channel; the inner side of the front end of the pipe is provided with a partition plate, a protruding rod extends outward from the center of the partition plate, and a vent hole is located at one side of the protruding rod a piston, a ruler, a set of plugs, and a pressure spring are placed under the self-contained baffle. a ruler and abutting the piston and the plug respectively, the plug is embedded at the rear end of the conduit and has a hole for the ruler to protrude outward; a first cover is on the inner side thereof The cover surface is provided with another semi-circular channel opposite to the semi-circular channel of the housing base, and the first housing cover is attached to the inner side of the housing base and the semi-circular channel is provided.
