摘　　要：借助拐杖辅助行走的老年人,在上楼梯时需要与地单点接触的拐杖的支撑,如质心不稳,则容易跌倒。对此,设计了楼梯平地两用折叠拐杖。介绍了这一拐杖的结构,分析了这一拐杖的原理,并进行了尺寸计算和强度、刚度校核。这一拐杖具有折叠和展开两种状态,展开时可以辅助老年人上下楼梯,折叠时作用与普通单拐相同,具有推广应用价值。The elderly who uses crutch to assist in walking need the support of the crutch that is in contact with the ground at a single point when going up the stairs,if the center of mass is unstable,the elderly will be easy to fall.In this regard,a folding crutch for both stairs and ground was designed.The structure of this crutch was introduced,the principle of this crutch was analyzed,and the size calculation and strength and rigidity checks were carried out.This crutch has two states of folding and unfolding.When unfolded,it can assist the elderly to go up and down the stairs.When folded,it has the same function as an ordinary single crutch,which has the value of promotion and application.
