fourthly, unfolding the expansion side wall and the expansion bottom plate: promote the extension side wall, the upper portion pulley of side wall board slides on the last track of extension gable board, the lower part skidding of side wall board is at the lower bottom track of extension gable board and is moved, through upper and lower both sides pulley, guarantee the horizontal direction removal of extension side wall, along with the extension side wall by the incasement to the removal of incasement outside, the extension side wall board drives folding bottom plate A, B motion through the bottom hinge, the rotatory 180 degrees of hinge between folding bottom plate B and the folding bottom plate A, open folding bottom plate A, B completely, the vertical wallboard of extension side wall is located the roof below, accomplish the expansion in extension square cabin, it is fixed with the fastener to extend side wall and extension roof.

10. A method of deploying an extended shelter according to any one of claims 1 to 8, wherein: comprising an unfolding and folding method, wherein the folding method is the reverse of the unfolding method, comprising the steps of:

folding of the expansion side wall and the expansion floor: detaching the fastening pieces of the expansion side walls and the expansion top plate, enabling the folding bottom plate A, B to simultaneously move upwards around the hinge and drive the expansion side walls to move towards the inner side of the box body through the bottom plate lifting device, and enabling the folding bottom plate A and the folding bottom plate B to be mutually close to each other in the fixed cabin after the expansion side walls reach the preset position of the inner side of the box body;

secondly, expanding the folding of the gable panel: the four expansion gable panels are respectively rotated inwards by 90 degrees in the vertical direction around the upright posts, so that the expansion gable panels are parallel to the expansion side walls, and the expansion gable panels are fixedly connected with the box body through a positioner;

thirdly, expanding the folding of the top plate: the two extension top plates move downwards around the hinges respectively to be in a vertical state, the two extension top plates are located on the left side and the right side of the fixed cabin respectively to form a container, folding is completed, and the bottom support frame is collected.
