[0032] The working principle and use process of the utility model are as follows: when the automobile tire pressure detection device is used for detection, the operator first holds the installation head 104, and clamps the end of the installation head 104 on the valve of the automobile tire. The outer reinforcement installation cylinder 1041 is closed accordingly. When the end of the installation head 104 contacts the surface of the valve, the rotating block 1045 is driven to rotate in the rotating groove 1044 by turning the dial ball 1042 to rotate the outer reinforcement installation cylinder 1041 on the outer surface of the installation head 104. When the outer reinforcement installation cylinder 1041 rotates, the inner thread ring 1043 and the thread on the outer surface of the valve are driven to rotate until the outer reinforcement installation cylinder 1041 is completely rotated and fixed, and then the end of the installation head 104 is driven to be completely clamped in the inside of the valve. It is convenient for appropriate clamping installation, and the installation is not easy to leak and cause damage to the valve. The tire pressure detection is convenient to install, which improves the convenience of the tire pressure detection device body 100 to press and install the installation head 104 during automobile tire pressure detection, and accurate detection and use are achieved.

[0033] Then, after the mounting head 104 is pressed and installed, the switch button is pressed, and the tire pressure detection device body 100 is started, and the number displayed on the digital display is the air pressure value inside the tire at this time;

[0034] Finally, after the tire pressure detection device body 100 is used, the elastic card body 1055 is engaged with the inside of the card hole 1054 to install the compression sealing gasket 1053 inside the installation groove 1052. At this time, after the installation head 104 and the external reinforcement installation tube 1041 are separated from the valve stem, the sealing plug 105 is engaged with the bottom end of the external reinforcement installation tube 1041, and the compression sealing gasket 1053 is deformed and pressed against the inside of the compression groove 1056 to press and fix the sealing plug 105, thereby facilitating the compression and sealing protection of the bottom end of the external reinforcement installation tube 1041. When not in use, it is not easy for dust to enter the inside of the external reinforcement installation tube 1041 and the installation head 104, and it is not easy to cause dust to enter the inside of the installation head 104. When used again, effective and accurate tire pressure detection is performed, thereby improving the convenience of protecting the installation head 104 of the tire pressure detection device body 100 after the automobile tire pressure detection.
