| Zusammenfassung: | The utility model relates to a metal frame structure, which is characterized in that convex structures are in pressing fit with holes correspondingly, the convex structures generate expansive plastic deformation after bearing external action force and being extruded by the holes and then are combined with outer frame metal sheets and isolating metal sheets, thereby forming the metal frame structure. The metal frame structure has high flatness and strength. |
