Recessed angle brackets are fixedly connected with two side vertical beams and a lower crossbeam of the outer frame part. T-shaped profiles are fixedly connected with an upper crossbeam of the inner frame part. O-shaped profiles are fixedly connected with two side vertical beams and a lower crossbeam of the inner frame part. The T-shaped profile and the U-shaped angle bracket are fitted together. The O-shaped profile and the recessed angle bracket are fitted together. According to the present invention, all parts are integrally, firmly, and sealingly mounted at corresponding positions of the outer frame part and the inner frame part so as to avoid losing due to vibration during travelling.10 FIG. 6 FIG. 7
