The utility model discloses a goods upset frame puts up structure, including the underframe seam, the both sides of underframe seam articulate respectively and are provided with the baffle seam, the baffle seam includes baffle entablature and baffle bottom end rail, the baffle entablature with end cap and rear plug before being equipped with respectively between the both ends around the baffle bottom end rail, the upper surface parallel and level of underframe seam, the internal surface parallel and level of baffle seam. The baffle seam is frame type, not only alleviates self weight but also proof strength rigidity and does not subtract, because baffle seam internal surface parallel and level the upper surface parallel and level of underframe seam for the SMC board provides effective restriction of the sticky plane and the three -dimensional degree of freedom, utilizes its frame construction's advantage effectively to solve the light -weighted problem of packing box self weight to it provides the bed board requirement of fully -flattened for laying the SMC board to reach to satisfy.
