【技术实现步骤摘要】
一种手摇自行车
本专利技术涉及一种自行车,尤其是一种用于锻炼身体的自行车。
技术介绍
随着人民生活水平的提高,人民群众锻炼身体的愿望越来越强烈,室外骑自行车锻炼更受群众喜欢。但目前普通自行车是脚踏试,双脚交替运动,实现自行车的前行和人的锻炼,因此,双腿虽然得到活动,但人的上半身运动不足,特别是腰和双臂,得不到锻炼。现有的手摇的自行车,为左右手交替运动,对腰及下肢运动效果很小。
技术实现思路
本专利技术针对以上问题,提供了一种能够实现腰及全身运动的自行车。本专利技术的技术方案是:一种手摇自行车,包括车架、前车轮、后车轮,手摇自行车还包括从动轮、主动轮、旋转套、支撑杆、支撑座;从动轮固定连接前车轮,从动轮与前车轮同轴;旋转套安装于车架前部,支撑座活动套接在旋转套上,支撑杆固定连接于支撑座上;主动轮安装于支撑杆上端,从动轮安装于支撑杆下端,主动轮通过链条带动从动轮转动;主动轮中心设有轴,轴可轴向转动地安装于支撑杆上端,轴的左右两端固定设有力臂,力臂的一端与轴固定连接,另一端设有手柄,轴的左右两端的力臂相互平行;力臂与支撑座之间设有回转单元。回转单元包括弹簧、设于主动轮上的凸 ...
