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

Abstract

The invention discloses a projection curtain support having a stable use state. A curtain accommodation barrel (5) is disposed on a supporting rod (1) by a first adjusting mechanism, and a first locking bolt (8) is unscrewed, and then a slider (7) is capable of sliding upwards and downwards on the supporting rod (1) to adjust the position. A straight rod part (3.2) is disposed on the top end of the supporting rod (1) by a second adjusting mechanism, and a second locking bolt (10) is unscrewed, and then the height of the curtain hook (3) is adjusted. A middle segment of a rigid hanging thread (11) is set to be a projection segment (15). The accommodation barrel is fixedly disposed on the supporting rod by a rotating shaft, and the accommodation barrel is vertically arranged to realize storage, and when the accommodation barrel is horizontally arranged, the curtain can be pulled out for use. The curtain and the support can be conveyed and stored integratedly. The middle segment of the rigid hanging thread is the projection segment, and when the curtain is hung up, the curtain hook is stably clamped in the projection segment, and therefore the curtain is prevented from swinging leftwards and rightwards during the use.

Description

technical field [0001] The invention relates to a screen support structure, in particular to a projection screen support with a stable use state. 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 l...
