摘要 设计主题是家用多功能保健装置。它由腿部练习腰部练习、手臂练习和框架组成。腿部运动机构利用链条传动工作原理和飞轮的优点来实现锻炼腿部肌肉作用。腰部训练机构利用曲柄滑块机构工作原理和弹簧的优点，实现锻炼腰部肌肉作用。手臂锻炼机构使用操作机构（摇臂和钢丝绳）、导杆（双导杆）、调节机构（杆）满足有效组合，达到锻炼手臂肌肉效果；TH.REE为该设计提供了合理组合平台。另外，此实用新型健身器具有方便、安全、成本低、噪音小等优点。 高速前进的同时，中国健身器材一些问题也慢慢暴露出来。最主要就是在国际市场缺乏出名品牌而且功能比较单一。目前中国大部分制造企业还停留在仿制阶段，在产品研发与创新方面与国外该类企业相比较还有着明显不足。与国外相比较，该类产品于普通家庭中使用率以及平均每人投入到其中消费份额还比较低。 因此，中国健身器材工业企业必须抓住新的发展形势，加大科技创新，努力提高产品质量，加强自主研发能力，有关部门应尽快制订出健身器材统一技术安全标准，加强售后服务。只有这样才能在新形势下立于不败之地。 关键词：多功能；健器；机构；锻炼 Abstract The theme of this desig
