[0036] combine Figure 1-3, a waist adjustment device for lying down in the department of nephrology, comprising a bed body 1 and support legs 2 arranged at the bottom of the bed body 1, the adjacent support legs 2 are connected by beams 3, the bed body 1 includes bed board one 101 and bed board two 102 connected by a folding mechanism 11, the bottom of the bed board one 101 is connected to the beam 3 through the electric push rod 6, the bottom of the bed board two 102 is provided with a groove, and the center of the groove The two-axis motor two 9 is fixed by the ear plate 8, the output end of the two-axis motor two 9 is connected with a support 4 by a ball screw pair 10, the upper end of the support 4 is welded with a waist nursing pad 5, and the nursing pad 5 From the surface to the inside, it includes a fiber outer layer, a thin cotton layer, a correction board, a graphene fiber layer, a cotton cloth layer, and a medicine bag. The correction board is arranged longitudinall...
Embodiment 3
[0039] The folding mechanism is made of aluminum alloy, and the chemical composition of the aluminum alloy material includes zinc 4-4.07wt%, magnesium 1.25-1.3wt%, chromium 0.16-0.19wt%, zirconium 0.12-0.14wt%, titanium 0.02-0.06 wt%, iron 0.02-0.04wt%, silicon 0.38-0.1wt%, and the balance is aluminum.
[0040] The Brinell hardness Y of the aluminum alloy material is 80-93, the tensile strength K1 is 250-198MPa, and the yield strength K2 is 265-296MPa. The Brinell hardness Y and tensile strength K1 of the aluminum alloy material satisfy Y= β·K1, wherein, β is the hardness coefficient, the value range is 0.48-0.66, and the Brinell hardness, tensile strength K1, and yield strength K2 of the aluminum alloy satisfy the following relationship: K1 / K2=μ·Y 2 / 3 , where μ is the relationship factor, and the value range is 0.10-0.14.
[0041] By setting the range and relationship between the hardness and tensile strength of the aluminum alloy, the realization of the overall lightweight ...
