Projection curtain storage device

Abstract

The invention provides a projection curtain storage device. One end of a connecting shaft (6) is rotationally connected with a curtain storage barrel (5); the other end of the connecting shaft (6) is fixedly connected with a slide block (7); a locking screw bolt (8) passes through the slide block (7) to be jacked and pressed onto the outer wall of a support rod (1); the lower surface of a curtain hook (3) is provided with a clamping part (9); the end part of the curtain storage barrel (5) is provided with a clamping matching part (10); a position limiting ring (13) is arranged in a position so that when the slide block (7) is jacked to the position limiting ring (13), the end part of the curtain storage barrel (5) is just jacked to the lower surface of the curtain hook (3). During the storage, the clamping part is clamped into the clamping matching part, and the fixation on the storage barrel can be realized; the swinging cannot easily occur; the fixation effect is good; the curtain hook simultaneously has two effects of fixing the storage barrel during the storage and hanging the curtain in the use process; the design is ingenious; a single storage barrel fixing mechanism is omitted; the structure is simple.

Description

technical field [0001] The invention relates to a projection screen storage device. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen, and can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal; Now it is widely used in home theaters, office meetings, schools, billboards and many other places, with various types. [0003] The screen dedicated to projection is called projection screen, which is one of the most commonly used products in projector peripheral equipment. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. At present, the common small screen specifications on the market are roughly 72 inches, 84 inches, 100 inches, 120 inches, 150 inches, etc. Because the curtain generally has a large area, it needs to be folded on the reel rod when carrying...

AI Technical Summary

Problems solved by technology

Because the curtain generally has a large area, it needs to be folded on the reel rod when carrying it. The traditional curtain reel rod and the bracket are independent of each other, and the transportation or storage are independent of each other. Fixed to the bracket, very inconvenient to install and use
