Tire pressure sensor air valve lock

Abstract

To provide an air valve lock of a tire air pressure sensor having progressiveness and capable of achieving primary lock of one-step mounting.SOLUTION: A tire air pressure sensor main body has an abutting part between two guide wings. The two guide wings have opposing two position-limiting ridges. A side connected to the abutting part at one end of the two position-limiting ridges gradually enlarges, curves, and extends, and an enlarged end is formed at the other end. A compression groove is formed between the two position-limiting ridges and the abutting part. An air valve includes a shell, a nut, and a connector connected to one end of the shell. The nut is screwed in the shell. The connector has assembly ends on both sides extending from the shell and an abutting salient protrusively provided in one side of the assembly ends. The connector of the air valve is engaged with the compression groove at the assembly end, and the abutting salient is abutted inside the two position-limiting ridges. The nut spirally rotates the shell, and comes closer to the connector. The abutting salient presses and installs the two position-limiting ridges.SELECTED DRAWING: Figure 1
