Folding box for loading photovoltaic silicon wafers

The utility model relates to the technical field of logistics transportation, in particular to a folding box for loading photovoltaic silicon wafers, which is made of EPP (expanded polypropylene) foam materials and has high buffering performance and high part protectiveness, an outer box can be folded and recycled, and the recycling ratio is high, so that the transportation cost is reduced. Comprising a top cover, long side plates, short side plates, a base, hinges and clamping groove parts, protrusions are arranged at the bottoms of the long side plates and the short side plates, the two long side plates and the two short side plates are buckled on the base through the protrusions, the top cover is rotationally connected with the two long side plates through the multiple hinges, and multiple grooves are formed in the long side plates. Wherein two groups of clamping groove parts are respectively clamped on the two groups of short side plates and are connected with the two groups of long side plates, and the o
