MECHANICAL PROPERTIES OF THE SELF LOCKING MECHANISM OF THE HOOK AND THE DEVELOPMENT OF A NEW TYPE OF CLOTHES DRYING DEVICE

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.
