[0029] See also Figure 1-Figure 5 As shown, the utility model provides a foldable electric smoke barrier, including a tubular motor 2, a steel wire rope 4, a fireproof curtain 7 and a formed splint 8. The tubular motor 2 cooperates with the reel 3 to drive the reel 3 to rotate. The steel wire rope 4 is wound around the reel 3 and extends through the pulley 5; a plurality of formed splints 8 are provided on the fireproof curtain 7, and these formed splints 8 are evenly arranged at equal intervals. The end of the steel wire rope 4 is fixedly connected to one of the formed splints 8; the steel wire rope 4 is rotated and pulled by the tubular motor 2, and the fireproof curtain 7 above the formed splint 8 to which the steel wire rope 4 is fixedly connected is folded layer by layer and stored above the ceiling 10. A steel wire rope buckle 9 is provided on the side of each formed splint 8.
[0030] When the above technical solution is adopted, the motor rotates to pull the steel wire rope 4 during use. The steel wire rope buckle 9 on the fireproof curtain 7 can vertically limit the steel wire rope 4. The setting of the forming splint 8 allows the fireproof curtain 7 to be folded layer by layer.
