Projection screen need be when outdoor construction, can be respectively to aerifing the frame, aerifing the horizontal pole, aerifing the montant and aerify the support column and aerify, then utilize each magnet group to assemble fast and build, can be in very short time quick and convenient build the shaping to projection screen, it is very convenient to use, because each part is inhaled through magnet group magnetism and is connected, therefore can realize dismantling fast.

Therefore the utility model relates to a modular projection screen of aerifing can make things convenient for projection screen to build and assemble at open air fast, and convenient to use has realized projection screen's quick assembly disassembly.

Further, the inboard of inflating the frame is provided with the magic subsides, the curtain is pasted through the magic and is pasted and fix on inflating the frame, consequently can install fast and fixed curtain through the magic subsides.

Furthermore, the side walls of the two inflatable vertical rods are respectively provided with a plurality of pressing sheets extending outwards, when the projection screen is in a strong wind outdoor environment, the projection screen can be fixed by pressing outdoor stones and other heavy objects on the pressing sheets, and the influence of wind power is avoided.

Furthermore, the inflation frame, the inflation cross bar, the inflation vertical bar and the inflation support column are respectively provided with an inflation valve.

The utility model has the advantages that:

projection screen need be when outdoor construction, can be respectively to aerifing the frame, aerifing the horizontal pole, aerifing the montant and aerify the support column and aerify, then utilize each magnet group to assemble fast and build, can be in very short time quick and convenient build the shaping to projection screen, it is very convenient to use, because each part is inhaled through magnet group magnetism and is connected, therefore can realize dismantling fast. Therefore the utility model relates to a modular projection screen of aerifing can make things convenient for projection screen to build and assemble at open air fast, and convenient to use has realized projection screen's quick assembly disassembly.
