The invention relates to a lactation shielding device and a utility car with the same. The lactation shielding device comprises a shielding curtain by which lactation space is defined and a shielding-curtain installing base for hanging the shielding curtain, and the shielding curtain comprises a top edge and a bottom edge; the top edge is fixed on the shielding-curtain installing base, a vertical drawing mechanism is connected to the bottom edge, and the shielding curtain is in an upward-stacked folding state and a downward-unfolding shielding state under drawing of the vertical drawing mechanism; or the shielding curtain has side edges connected between the top edge and the bottom edge, a shielding-curtain guiding rail is arranged on the shielding-curtain installing base, sliding blocks are evenly arranged on the shielding-curtain guiding rail, and the top edge is fixed on all the sliding blocks to allow the shielding curtain to be in a folding state stacked in the horizontal direction and to be in a shielding state unfolded in the horizontal direction. The shielding curtain can be stacked or unfolded, the lactation space can be defined during unfolding, space can be vacated during folding, lactation is conveniently carried out in public places, and waste of public resources can be avoided.
