A collapsible rack includes symmetric support frames composed of vertical bars and horizontal bars and top and bottom frames connected between the support frames in a movable manner. The top and bottom frames are composed of connected movable left and right boards, which have front and rear faces that define recessed channels. Spaced fitting holes are defined in the channels. Straight bars form pegs. The top and bottom frames are of movability to allow the top and bottom frames to be collapsed to a stacked flat configuration when the rack is not in use, so as to facilitate storage and transportation. When the rack is to be used, the top and bottom frames are expanded and the straight bars are set to have the pegs fit in the fitting holes defined in the left and right boards to fix the top and bottom frames in the expanded position.
