[0002] A folding box is a special container. When the empty box is returned, multiple folding boxes can be stacked and interlocked together, thereby reducing the space occupied during return transportation. The folding box generally includes a base frame and two end walls located at both ends of the base frame. A fixed hinge is connected to each of the four end corners of the base frame, and movable hinges are connected to both sides of each end wall. The movable hinges on both sides of the end wall are respectively connected to two fixed hinges at one end of the base frame. The movable hinges are pivotally connected to the fixed hinges through hinge pins. In this way, the end wall can rotate relative to the base frame and can be folded and placed horizontally on the base frame.
