Further, be provided with again installing hole at the two ends of cross bar, for through bolt by mounted to a wall for curtain or wire rope handling is sub that curtain is hung over object.
Beneficial effects of the present invention is mainly manifested in: cost is low, carrying portable, easily install.
Accompanying drawing explanation
Fig. 1 is the structure schematic diagram of one embodiment of the present invention.
Fig. 2 is the side structure schematic diagram after curtain is rolled by one embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings, one embodiment of the present invention is further described.
A kind of simple projection screen, as shown in Fig. 1 ~ 2, including curtain 1, cross bar.Described cross bar, is made up of two semicircular pipe 2a, 2b, and two semicircular ribbons 3 that are provided with between pipe 2a, 2b connect, and when two semicircular pipes close, cross bar is hollow cylindrical shape；Being provided with multiple strong magnets 4 in the inner side of first half-tube 2a, be provided with multiple sucker 5 in the inner side of second half-tube 2b, staggering in the position of Magnet 4 and sucker 5 arrangement so that will not encounter together when pipe closes.Described curtain 1, is fixedly connected on second half-tube 2b.
Be designed with installing hole 6 at the two ends of first half-tube 2a and second half-tube 2b, for through bolt by sub for mounted to a wall for projection screen or wire rope handling furred ceiling or other object that curtain hung over.
Half-tube 2a, 2b recited above use aluminium alloy or plastics to be material；Described curtain 1 is manufactured into thinner the most as far as possible, makes the weight saving of whole projection screen.
When using projection screen recited above, two half-tube 2a, 2b are opened；If the metope installed is smooth, can directly press half-tube 2b, be adsorbed on metope by sucker 5；If having ironwork on the metope installed, can directly be adsorbed thereon by the Magnet 4 on half-tube 2a.The most also through installing hole 6, projection screen can be hung over somewhere with rope, it is also possible to directly pass installing hole 6 by wall fixing for projection screen with bolt.
When packing up projection screen, first two half-tube 2a, 2b are closed, then by curtain volume 1 on cross bar.
Embodiments described above, is only the implementation example of the present invention；It will be apparent to those skilled in the art that under the premise without departing from the principles of the invention, some changes made, all should be considered as belonging to protection scope of the present invention.
