The invention discloses a skeleton structure for quickly opening equipment, which is composed of a plurality of hollow bone structures made of flexible materials with sealing characteristics, wherein the plurality of hollow bone structures are communicated; in a non-use state, the hollow bone structures are folded and stored; and in a use state, hollow cavities of the hollow bone structures are filled with media. The skeleton structure disclosed by the invention is capable of replacing most of the existing skeleton structures, is suitable for being used in some devices needing to be quickly opened, can be applied to high-altitude escape devices, can also be applied to aerospace fields, such as opening of space detector solar sails and support of signal receivers, can effectively reduce the use of metal machines, greatly reduces the emission weight of a space detector, improves the detection capability of the detector, and has wide application prospects.
