A folding bed is provided, which includes a bed sheet, a first lateral supporting rod connected to a first edge of the bed sheet and a second side supporting rod connected to a second edge of the bed sheet. The folding bed further includes a first L-shaped supporting rod having a first end articulated to the first side supporting rod, a second L-shaped support rod having a first end articulated to the second side supporting rod, a gear connected to a second end of the first L-shaped supporting rod, and a gear locking member connected to a second end of the second L-shaped supporting rod. The gear locking member is provided with teeth which are rotatable in only one direction with respect to teeth of the gear. The folding bed is has a small size after being folded, is convenient to assemble and is easy to fold.

A sofa structural frame comprises a plurality of sofa modules, seat frame components, splicing pieces and supporting pieces which are combined to form a sofa frame, wherein the sofa modules comprise a backrest frame and armrests made by a molding process, the armrests are arranged on the two sides of the backrest frame by the splicing pieces, and the seat frame components are arranged between the armrests on two sides by the supporting pieces; connecting parts are formed on the surfaces of the armrest and the backrest frame; a mounting part is formed on the surface of the armrest; the splicing pieces comprise a first connector and a second connector which are connected with each other; the supporting pieces are configured to be connected with the mounting part and the seat frame component respectively in a clamping manner.

A folding support and a folding bed are provided. The folding support includes a supporting crossbar and a folding assembly arranged at each of two ends of the supporting crossbar. The folding assembly includes a connecting base, an upper supporting rod, and a lower supporting rod. The connecting base is fixedly mounted at an end portion of the supporting crossbar. The upper supporting rod is rotatably connected to the connecting base. The lower supporting rod is rotatably connected to the upper supporting rod. The upper supporting rod and the lower supporting rod are configured to rotate in an identical plane to implement folding and unfolding of the folding assembly. When the folding assembly is folded, the upper supporting rod and the lower supporting rod are folded toward each other, and the upper supporting rod and the lower supporting rod are positioned adjacent to a side of the supporting crossbar.
