Document Type and Number:
WIPO Patent Application WO/2021/073532
Kind Code:
A1
Abstract:
A packaging device for a projection screen, applied to a rectangular projection screen. Said device comprises at least two L-shaped packing materials (11), a strip-shaped distance limiting packing material (12) and a mounting hole limiting packing material (13); each L-shaped packing material (11) comprises a first arm (111) and a second arm (112), and when mounting a rectangular projection screen onto a mounting wall surface (40), the distance limiting packing material (12) is used for limiting the vertical distance from a projection device (20) to the mounting wall surface (40), and first arms (111) of the two L-shaped packing materials (11) clamp side surfaces of the projection device (20) and are used for limiting a light emitting surface of the projection device (20) to be parallel to the mounting wall surface (40); a mounting hole width limiting packing material (131) is lifted by the second arms (112) of the at least two L-shaped packing materials (11), and is used for limiting the horizontal width between mounting holes of the rectangular projection screen; and two mounting hole height limiting packing materials (132) are lifted by the mounting hole width limiting packing material (131), and are used for limiting the vertical height between the mounting holes of the rectangular projection screen. The packaging device can reuse packing materials of the projection screen, and the packing materials of the projection screen are used as limiting components, achieving accurate mounting and positioning of the projection screen.
