Abstract

一种儿童三轮车,包括车体1,车把2,前车架3, 前车轮4,后车轮5,螺栓6,螺母7构成,应用力学原 理,车把2到前车轮4的力矩大于前车轮至螺栓6的 力矩,坐在车体1上的儿童摇动车把2,会带动三轮 车蛇形前行,达到娱乐及锻炼儿童臂力的目的。

Description

本实用新型涉及一种儿童三轮车。
目前一般的儿童三轮车靠脚踏行,仅能锻练儿童的腿部力量,儿童的臂力得不到锻练。
本实用新型的目的在于提供一种能够使儿童臂力得到锻练的三轮车,克服三轮车仅锻练腿部力量的缺点。
本实用新型的技术方案是把儿童三轮车的一对前车轮4安装在一个前车架3上,前车架3的另一端安装车把2,在前车架3上开有一前架孔9,前车架3由螺柱6和螺母7与车体1相连,车体1前端有一对支点轴承8与螺栓6相配合,前车架3以螺栓6为轴可左右转动,转动车把2时,前车架3以前车轮4为支点转动,带动车体1随之弧形前移,如此往复,车体会蛇形前行。
与现有的儿童三轮车相比,本实用新型能够在娱乐中锻练儿童的手臂力量,具有有益的效果。
图1是本实用新型的侧视示意图;
图2是本实用新型的俯视示意图。
图中1车体、2车把、3前车架、4前车轮、5后车轮、6螺栓、7螺母、8支点轴承、9前架孔。
结合附图对本实用新型的实施例作详细说明。
车体1的后方安装有左右二个后车轮5,车体1的前端有一对支点轴承8,前车架3的一端二侧装有左右二个前车轮4,前车架3的另一端装有车把2,车体1与前车架3由螺栓6穿过前架孔9与螺母7配合相连,螺栓6与车体1上的支点轴承8相配合,前车架3能绕螺栓6为轴左右转动,当儿童坐在车体1上向右摇动车把2时,前车架3以右侧前车轮4为支点向右转动,通过螺栓6带动车体1向右前方弧形,当向左摇动车把2时,前架3以左侧前车轮4为支点向左转动,车体1随之向左前方弧形移动,如此往复带动车体1蛇形前行。
