The main function of the hinge pins is to secure various parts of the folding container, including the front and rear wall panels, side wall panels, and roof panels. By fixing with hinge pins, the connections between the various parts of the container become more stable, ensuring the integrity and stability of the container structure. In addition, the internal hinge pins of the folding container allow for quick assembly, disassembly, and movement when needed. Through the fixation provided by hinge pins, the container can be folded or unfolded as a whole when necessary, facilitating convenient transportation, shipping, and storage.
