Description

Inner hidden type hinge structure for folding building and folding method Technical Field The invention relates to an inner hidden type hinge structure for a folding building and a folding method. Background The folding building has the advantages of being fast to build and convenient to transport, is widely applied to scenes such as emergency rescue, field operation and temporary office work, and the hinge structure is a core component for realizing unfolding and storage of the folding building. But the existing folding building hinge structure has a plurality of defects. If the existing hinge is mostly in an exposed design, the integrity of the appearance of the building is damaged, and the hinge is easily corroded by rainwater, sand dust and external force, is easy to block, deform and rust after long-term use, and causes the reduction of folding and unfolding stability. And the hinge is unfolded without an effective locking structure, so that the hinge is easy to release and retract in the use process, and the safety of the building structure is influenced. And when articulated installation, need destroy panel body structure, the assembly is loaded down with trivial details, and can't realize the hidden overall arrangement of integration with folding building panel. Based on the above problems, there is a need to develop a hidden folding building hinge structure with smooth overturning, locking and strong adaptability and a matched folding method. Disclosure of Invention The invention provides an inner hidden type hinge structure for a folding building and a folding method, which aim to solve the technical problems that the existing hinge structure of the folding building is exposed and easy to damage, has no effective locking and is complicated to install. An inner hidden type hinge structure for a folding building comprises a left rotating block and a right rotating block, wherein the left rotating block and the right rotating block are connected in a rotating way through a plurality of arc-shaped blocks which can be alternately turned and overlapped to form a line contact turning mechanism; the hinge structure is integrally embedded in the frame of the folding building panel, so that the inner hidden installation is realized, and the hinge structure is provided with a locking structure after being unfolded and used for limiting the rotation of the hinge structure.
