The present invention relates a blow-molded case and the strengthened structure thereof. The blow-molded case has a housing which is composed of an inner shell and an outer shell. The inner shell and the outer shell are connected at a first position by a connecting piece so that a cavity is formed between the inner shell and the outer shell. The inner shell and the outer shell are at least partially pressed together at the corner of the housing so that the connecting piece, the inner shell and the outer shell enclose to form a closed support structure. The implementation of the present invention can realize a blow-molded case of higher strength and higher resistance to impact. |
