The invention aims at providing a logistics packing box which is convenient to use, firm, durable and capable of being recycled and repeatedly used so as to solve the problems that a traditional logistics packing box cannot resist impact and is prone to cracking and hole breaking, after being used one time, the box becomes waste, and cannot be recycled, due to rapid development of electrical business logistics needs, social environment pollution is caused, and giant resource consumption is caused. Under the initial state, the packaging box is a hexahedron and is flat and unfolded, when the boxis used every time, the hexahedron can be conveniently and rapidly assembled into the logistics packing box, after being used, the box can be rapidly and conveniently recovered into the initial state, the box can be conveniently recycled, bundled, packaged and transported, modules of the same size of the packaging box can be interchanged, in order to achieve the aim, the packaging box is designedinto three single modules including a bottom plate module, a side surrounding plate module and a cover plate module, the bottom plate module serves as the center and can be connected with other modules, connected edges are provided with hinge type complementing structures, the modules are assembled and combined through hinges, pin rods are inserted, and the box is formed through connection.
