The invention provides a trackless electric retractable door. The trackless electric retractable door is characterized in that a first middle support is arranged between each two adjacent first door frames, first connecting rod groups are arranged between the adjacent first door frames and the adjacent first middle supports, and cross joints of first connecting rods are connected with the first middle supports or first support rods by first pull springs; a second middle support is arranged between each two adjacent second door frames, second connecting rod groups are arranged between the adjacent second door frames and the adjacent second middle supports, and cross joints of second connecting rods are connected with the second middle supports or second support rods by second pull springs. The trackless electric retractable door has the advantages that door rows can be pulled by the first connecting rod groups and the second connecting rod groups to move when a first retractable door and a second retractable door are about to move, so that the retractable doors can be contracted or spread, the first connecting rod groups and the second connecting rod groups are low in stress and can be prevented from deforming or being broken, the integral stability of the retractable doors can be guaranteed, guide tracks on the ground can be omitted, and the retractable doors can stably run and can constantly keep linearly running.
