Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning machines, and specifically relates to a limiting mechanism for a VR glasses frame. Background Art

[0002] The cleaning process of an industrial water-based cleaning machine is generally divided into two parts: cleaning and drying. Cleaning is to use cleaning media to remove dirt from the surface of parts by physical or chemical means. Drying is to use heat energy to vaporize the moisture (water or other solvents) in wet materials, and use air flow or vacuum to take away the vaporized moisture, thereby obtaining the operation of drying materials. It takes a lot of time (3-5 minutes) to use heat energy to vaporize the moisture in wet materials. Using compressed air to directly use air flow to take away the moisture will greatly reduce the drying time (within 10 seconds). Compressed air blowing materials will generate greater air kinetic energy.

[0003] In the existing cleaning equipment for VR glasses frames, when the VR glasses frames are blown dry by air after cleaning, the compressed air may cut the liquid and blow the VR glasses frames away or blow them out of position, so that the VR glasses frames cannot be dried well and the drying efficiency is low.

[0004] In summary, the present invention provides a limiting mechanism for a VR glasses frame to solve the above problems. Utility Model Content
