[0038] In a specific embodiment of the utility model, the galvanized square tube body 1 serves as the main body of the entire structure, providing basic support and an external frame. A plurality of buffer seats 2 are evenly distributed on the inner surface of the square tube body to provide an installation platform for the load-bearing mechanism. Each group is composed of a plurality of first connecting seats 11, an extrusion plate 12 and a second connecting seat 13. The first connecting seat 11 is fixed to the adjacent ends of the adjacent buffer seats 2 and is connected to the extrusion plate 12 through a rotating shaft.

It is composed of a sliding rod 17, a sliding shell 14, a second spring 15 and an extrusion block 16, which provide elastic support and restoring force for the entire square tube body, ensuring stability and durability when bearing load. The elastic restoring force of the second spring 15 helps the structure to return to its original state after the load is reduced or removed, ensuring the stability of the load-bearing and facilitating the galvanized square tube to have a load-bearing function. When multiple galvanized square tubes are stacked for transportation, deformation during stacking and under pressure is avoided, damage to the appearance of the galvanized square tubes is reduced, and the waste of resources of the galvanized square tubes is reduced.

[0050] In this embodiment, the extruded rod 7 is connected to the external structure through the connecting pad 8, which optimizes the stress state of the contact surface, reduces the wear or looseness that may be caused by direct hard contact between metals, and ensures the stability and durability of the connection.

[0051] The working principle and use process of the utility model are as follows: when an external load acts on the galvanized square tube body 1, the load is first evenly distributed through multiple buffer seats 2, and then transmitted to multiple groups of load-bearing mechanisms connected thereto. Multiple first connecting seats 11 and extrusion plates 12 in each load-bearing mechanism are connected by a rotating shaft to form a rotatable load-bearing system. When the load increases, the sliding shell 14 slides inward along with the sliding rod 17 driven by the second connecting seat 13 on the pressure side, compressing the second spring 15, thereby generating elastic force to resist external force and realize dynamic buffering.
