The invention discloses a venetian blind structure comprising a wheel frame, a lock belt device, a rotating wheel, a pulling belt, a plurality of venetian blind pieces and a plurality of adjusting mechanisms. The upper ends of vertical corner ladder belts are connected with rotating shells; elastic blind collecting pipes are arranged on rotating shafts and penetrate through all the venetian blind pieces in sequence from top to bottom; the upper ends of the elastic blind collecting pipes are connected with the rotating shafts, and the lower ends of the elastic blind collecting pipes are connected with the lowest venetian blind piece; following rods are arranged on the rotating shells; upper limiting rods and lower limiting rods are arranged on top frames; passive magnetic blocks are arranged at one ends of the rotating shells; and active magnetic blocks attached to the passive magnetic blocks are arranged on the rotating shafts. The venetian blind structure has the beneficial effects that the angles of the venetian blind pieces can be adjusted, the venetian blind structure can be wholly lifted up and opened, operation is easy and convenient, the integration degree of the structure is high; the structure has the function that double controlling is achieved through one line, the elastic blind collecting pipes can adjust angles of the venetian blind pieces and can also wholly collect the venetian blind pieces; and the elastic blind collecting pipes can be protected under a certain condition, so that the service life of the elastic blind collecting pipes is effectively prolonged.
