Description

Technical Field

[0001] The utility model relates to the technical field of aviation tire processing, in particular to an aviation tire air leakage detection device. Background Art

[0002] When tires leave the factory, they need to be tested for air tightness to see if there are any leaks. If there are any leaks, they need to be repaired in time. During the use of tires after leaving the factory, people often encounter tires that are punctured and leak. Therefore, it is very necessary to detect the leaks in tires.

The tire detection platform includes a transparent detection pool and a carrier plate. A base is fixed at the inner center position of the transparent detection pool, and a tire lifting and flipping mechanism is correspondingly arranged above the base. When the tire enters the water, a series of bubbles will emerge from the leaking part of its surface, thereby quickly determining the leakage location and saving a lot of time.
