The utility model relates to a load-bearing mechanical structure, in particular to a magnesium alloy bedstead of a sleeping berth on a truck. The magnesium alloy bedstead is characterized in that magnesium alloy extruded pipes with special sections are thermally bent into parts which are in symmetry in a left-and-right direction in a longitudinal direction, and the parts are riveted by U-shaped plates; transverse supporting pipes and an outer frame are connected by sheet metal parts of special structures; and the outer frame is wrapped with canvas, so that a bed surface can be formed.
一种用于承重的机械结构,尤其是卡车上卧铺镁合金床架,其特征是:用特殊截面的镁合金挤压管材热折弯成纵向左右两侧对称件,并用U型板铆接;用特殊结构的钣金件连接横向支撑管和外框;用帆布包裹外边框形成床面。
