After the screening, organize the audience to leave the greenhouse safely, turn off the power supply, untie the inflatable tube and exhaust. When the workshop automatically lands, untie the connecting buckle and the fixing rope, open the adhesive tape and the iron ring buckle, and fold along the arch beam, so as to exhaust the residual odor in the arch beam as much as possible. Put the folded studio into the packaging bag. This product is a combination of textiles, which can effectively avoid the danger of extrusion. Don't panic if the shed falls down slowly because of power failure. Evacuate quickly and orderly from both sides according to the operating rules to avoid trampling injury caused by crowding: good safety performance, good sunshade performance, good sound quality, good ventilation performance, quick operation, labor saving, good weather resistance, high cost performance and easy maintenance.
