Abstract: The present invention relates to a space shelf, and particularly to a folding and unfolding space shelf. The lower side of an upper backplane is hinged with the upper side of a lower backplane; one side of a top crossbeam is hinged with the upper side of the upper backplane; the other side of the top crossbeam is rotatably connected with one side of an upper stringer; one side of a bottom crossbeam is hinged with the lower side of the lower backplane; the other side of the bottom crossbeam is rotatably connected with one side of a bottom stringer; both ends of one side of the bottom stringer are hinged with middle stringers; both ends of the lower side of the lower backplane are respectively hinged with a backplane bottom stringer; and a backplane bolt assembly for realizing the relative angle fixation of the upper backplane and the lower backplane is installed on one surface of the upper backplane which faces each crossbeam and stringer. The present invention has the characteristics of novel structure, easy implementation of folding and unfolding processes, easy storage in a folding state and high stability after unfolding, and is suitable for occasions having high requirements for storage and folding-unfolding ratio in the aerospace field.

Abstract: The present invention relates to a quick clamping device. A pressing flange and a top plate are respectively installed on both sides of a bracket; one end of a top rod is rotatably connected with the top plate, and the other end is in threaded connection with a center pressing element; a slip ring copper sleeve is sleeved on the center pressing element; a synchronous slip ring can be sleeved outside the slip ring copper sleeve relatively movably; the outer end part of the slip ring copper sleeve is provided with a copper sleeve flange; a spring sleeved on the slip ring copper sleeve is arranged between the synchronous slip ring and the copper sleeve flange; both ends of the spring are respectively abutted against the synchronous slip ring and the copper sleeve flange; a plurality of pull rods are evenly distributed along the circumferential direction of a clamped element; one end of each of the pull rods is respectively hinged to the center pressing element, and the other end is a pressing end; the clamped element is positioned between the pressing flange and the pressing end of each pull rod; a connecting rod is connected between each of the pull rods and the synchronous slip ring; and both ends of the connecting rod are respectively hinged with the pull rods and the synchronous slip ring. The present invention has the advantages of novel structure, simple operation, small size, and the like.
