AI Technical Summary
In the existing spraying technology, the various sizes of holes on the oil tank shell are difficult to be effectively protected by a single plug, resulting in the spraying powder being easily contaminated with the holes.
A spray plug is designed including a conical table-type plug hole and a connection part. The plug hole and the connecting part are internal hollow structures, and gas inflation is achieved through the air intake hole and the air intake pipe. The blocking block can be used to seal the air intake pipe and ensure air tightness.
Due to its high versatile cone structure, this plug can be suitable for circular holes of various diameters, and enhances sealing by inflation after inflation, so as to effectively protect the holes from contamination during spraying.
