摘要:

针对常用晾衣方式空间利用率低,可调性差和防风性差的缺点,通过力学自锁原理设计一种弯钩自锁机构新型晾衣装置.依据弯钩自锁机构特点,采用静力平衡方程分析其力学特征,确定了危险截面、最优自锁角及材料的抗拉和抗剪强度,分析影响装置稳定性和材料安全性的控制因素.基于此,设计了弯钩自锁机构新型晾衣装置,实现了衣架节与立柱之间多方位多角度灵活调节,增强了新型机构的防风能力,可任意添加衣架节使得空间利用率得到提高,具有很好应用价值和良好的推广前景.

Abstract:

The common way of airing clothes has the disadvantages of low utilization ratio of space, poor adjustment capability and poor wind resistance. Based on the mechanical self locking principle, a new type of clothes airing device is designed. According to the hook self-locking mechanism and using the static equilibrium equation for the analysis of mechanical characteristics,the dangerous section, the optimal self locking angle and the tensile strength and the shear strength of the material are determined. The impact of the stability of the system and the material safety control factors are analyzed. A clothes airing device based on the hook locking mechanism is designed, with the hanger column angle adjustable, with an enhanced new mechanism of windbreak protection, and with arbitrary number of hangers. The space utilization is improved.
