First Claim
Patent Images
1. A tire gauge comprising:
- a housing;
a display panel mounted to the housing, with the display panel including a vertical scale for indicating depth of tread of a tire; and
a tread-measuring device comprising a base, a probe, and a slide block, with the base fixed to the housing, with the slide block and the probe slideably mounted to the housing, with the slide block including a plurality of drive teeth, with the slide block including a pointer, with the plurality of teeth of the slide block in gearing relation with the probe to move the slide block adversely to the probe, with the probe extending in the treads of the tire to indicate the depth of the tread by moving the pointer relative to the vertical scale.

Abstract
A multi-functional tire pressure gauge includes a housing, an air-guide seat, a diaphragm, a helical seat, an annular seat, a tread-measuring device, a display panel and an air-guiding device. The multi-functional tire pressure gauge can measure tire pressure and tread'"'"'s depth simultaneously. Specifically, when the diaphragm moves up and down under the effect of the tire pressure, the helical seat converts the up-and-down motion of the diaphragm into circular motion, so that the index pointer can display tire pressure value. Furthermore, the probe extending in treads of the tire can obtain the depth of the tread.
