Projection screen need when outdoor is built, can be respectively to aerifing the frame, aerify the horizontal pole, aerify montant and aerify the support column and aerify, then utilize each magic subsides to make two aerify and paste fixedly fast between the part, realize projection screen's fast assembly 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 pastes the connection each other through the magic, therefore can realize quick dismantlement.
Therefore the utility model relates to a dedicated projection screen of aerifing of outdoor construction 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 lateral wall of the inflatable vertical rod is provided with a plurality of water storage bags, when the projection screen is in the outdoor environment of strong wind, the weight of the projection screen can be increased by pouring water into the water storage bags, and therefore the projection screen can be fixed and the influence of wind power is avoided.
Further, a sealing cover is arranged at a water inlet at the top of each water storage bag.
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 when outdoor is built, can be respectively to aerifing the frame, aerify the horizontal pole, aerify montant and aerify the support column and aerify, then utilize each magic subsides to make two aerify and paste fixedly fast between the part, realize projection screen's fast assembly 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 pastes the connection each other through the magic, therefore can realize quick dismantlement. Therefore the utility model relates to a dedicated projection screen of aerifing of outdoor construction 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.
