Description

Technical Field

[0002] Spraying is an important process in the processing and manufacturing of many sheet metals, frameworks, mechanical parts, etc. Most mechanical parts, frameworks, sheet metal parts, etc. need to be spray-painted for beautification and protection to achieve the purposes of beauty and durability. The structural function and scientific rationality of the spraying hanger not only affect the spraying efficiency but also the spraying quality; at the same time, the structure of the hanger is directly related to the spraying method. Different spraying methods may have different spraying effects. Usually, the hanger is used to spray the sprayed parts in a movable hanging manner.

[0003] In the patented document with the publication number CN219985100U, the suspended marble positioning rotary hanger is recorded. By setting a rotatable suspension hook, it is convenient to operate multiple faces of the workpiece during spraying operations. And the suspension hook is fixed by a fixing nut, and with the nut gasket, the suspension hook can be installed more firmly to prevent loosening during use; the rotation positioning of the hanger is realized through the cooperation of positioning marbles and springs.

[0004] However, when using this device, it requires the operator to manually rotate the hanger. In industries such as automotive parts that require uniform spraying, manual rotation is difficult to meet the requirements, and the hanger cannot carry multiple parts at the same time, resulting in low single-time spraying efficiency.

[0005] Based on this, a rotatable spraying hanger is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model
