Description

Technical Field

[0001] The utility model relates to the technical field of home furnishing manufacturing, in particular to a completely zero-wall telescopic sofa bed. Background Art

[0002] The existing Chinese utility model patent with publication number CN221105329U and titled "A single sofa with multiple sitting and lying modes" requires that when in use, the fixing rod is taken out, and the angle of the second sofa cushion is adjusted by the first rotating rod. After the adjustment is completed, the fixing rod is passed through the circular hole in the fixing frame and the circular through-hole in the fixing block to stably fix the second sofa cushion, thereby adjusting the inclination angle of the second sofa cushion. When lying down, the second sofa cushion is put down, the telescopic rod is rotated out, and then the supporting column is rotated out, so that the telescopic rod and the supporting column are upright, and the second sofa cushion is supported. However, when the second sofa cushion is flipped, a flipping space needs to be reserved, and it cannot be placed against the wall, which wastes space and is not conducive to space layout.
