Abstract

The utility model relates to an under-frame adjustment device for a folding baby bed. The four vertical rods of the rectangular under frame of the utility model are provided with a plurality of clamping holes at the inner edge of a diagonal wire, and are provided with the positioning seat of an under rod along a diagonal direction. One end of the positioning seat is sheathed with the vertical rods, the other end is connected with the diagonal under rod, and the inner is fixed with a stretching element and an elastic element. The clamping projecting block of the stretching element penetrates into the clamping hole of each of the vertical rods to be clamped, and is provided with a central seat. The pivoting grooves of the extending sections of four sides of the central seat are positioned at the other end of the diagonal under rod, and the central point is provided with a wire winding ring which winds a fixing pull wire. The pull wire uses one end to wind a fixed position, extends towards four sides, and is connected with the tail end of the stretching element by passing through the diagonal under rod. The under-frame adjustment device can synchronously move up and down.
