An industrial spray gun cup structure includes a connector, a guide member, a collar and a cover body. A reception section of the cup is engaged with the guide member so that the cup can be only normally rotated without rotating and loosening other parts. The cup is integrally formed with inclined ribs which are tightly fitted with corresponding connecting sections of the cover body. While rotating the cover body by a certain angle, the ribs can be separated from or inserted with the connecting sections so as to open or close the cover body. Therefore, the cover body can be conveniently rotated to firmly and tightly fit with the cup without leakage.
