Overlapped push-open door

The invention discloses an overlapped sliding door which comprises a door frame and a plurality of door leaves, the door leaves are sequentially arranged in the transverse direction of the door frame, the door leaves are sequentially arranged along the inner side and the outer side of the door frame, and when one or more door leaves slide along the same side of the door frame, the door leaves and the other side of the door frame are opened. A rotating assembly is arranged on one side of the bottom of the door frame; the door leaf close to the outer side of the door frame is rotationally matched with one side of the door frame; and when the other door leaves transversely move to one side of the door frame, the other door leaves are rotationally matched with the rotating assembly, and when the inner sides of the door leaves are subjected to outward force, the door leaves all rotate towards the outer side of the door frame. When large-scale equipment needs to pass through, all the overlapped door leaves are rota
