Description

Technical Field

[0001] The utility model relates to the technical field of tire measurement, in particular to an aviation tire size measurement and fixing device. Background Art

[0002] A Chinese utility model patent with the patent authorization announcement number CN217585611U discloses a vehicle tire size measuring device, comprising an arc block 1 and an arc block 2. Each arc block 1 and arc block 2 are fixedly connected to a protrusion, each protrusion having a circular groove formed therein, and a round rod slidably connected within the circular groove. The round rod is sleeved with a spring. An indicator rod is fixedly connected to the arc block 1, and a scale adapted to the indicator rod is fixedly connected to the arc block 2. As the arc block 1 and arc block 2 gradually move away from each other, the indicator rod moves to a corresponding position on the scale, thereby enabling the wheel hub size, and thus the tire size, to be determined from the scale. This is a relatively convenient device, as the wheel hub and tire sizes match, so the tire size can be determined by determining the wheel hub size. The operation process is relatively convenient and quick, eliminating tedious steps, making it easy for operators to operate and saving time.

[0003] However, the above disclosed structure cannot stably fix the tire when measuring the tire. It only relies on the arc-shaped inner wall of the arc block to contact the outside of the tire, which is prone to errors. Therefore, when measuring aircraft tires, a fixed and stable device with smaller measurement errors is needed. Utility Model Content
