Description

体能测试用肺活量计
技术领域
本实用新型涉及一种体能测试所用的肺活量测量仪,尤其是体能测试用肺活量计。
背景技术
在体育领域中,肺活量是运动员一项比较重要的生理指标。肺活量测试需要用肺活量测量仪。而现有肺活量测量仪由于结构原因存在结构复杂,不利于推广应用。
发明内容
为了解决现有肺活量测量仪结构复杂的问题。本实用新型提供一种体能测试用肺活量计。该体能测试用肺活量计具有结构简单的特点。
本实用新型的技术方案是:该体能测试用肺活量计包括瓶体。密闭透明的瓶体下端有弯转90度吹气口,瓶体上端有出气孔,瓶体内轴向连接有滑柱,滑柱上滑动连接有推拉片及弹簧,弹簧两端分别与滑柱上端和推拉片相连接,瓶体外轴向标有刻度线。
本实用新型具有如下有益效果:该体能测试用肺活量计由于采用密闭透明的瓶体下端有弯转90度吹气口,瓶体上端有出气孔,瓶体内轴向连接有滑柱,滑柱上滑动连接有推拉片及弹簧,弹簧两端分别与滑柱上端和推拉片相连接,瓶体外轴向标有刻度线的结构,利用气流推动推拉片,由于弹簧拉力与伸长率成线性关系,因而通过刻度线测量到肺活量值,进而简化结构,使用方便。所以说该体能测试用肺活量计具有结构简单的特点。
附图说明:
附图1是本实用新型结构示意图。
图中1-瓶体,2-吹气口,3-出气孔,4-滑柱,5-推拉片,6-弹簧。
具体实施方式:
下面结合附图对本实用新型作进一步说明:
如图所示,该体能测试用肺活量计包括瓶体1。密闭透明塑料的瓶体1下端有弯转90度吹气口2,吹气口2的弯转有利于观察推拉片5所在刻度线位置。瓶体1上端有出气孔3,由出气孔3使推拉片5上部与外界连通,避免产生真空,影响测试。瓶体1内轴向连接有滑柱4,滑柱4上滑动连接有推拉片5及弹簧6,弹簧6两端分别与滑柱4上端和推拉片5相连接,由气流推动推拉片5在滑柱4上滑动,利用弹簧6的拉力反向作用,测出肺活量。瓶体1外轴向标有刻度线,由于弹簧拉力与伸长率成线性关系算出并标在瓶体1外,当推拉片5到某一刻度线时,就是所测出的肺活量。
实际使用时,被测运动员将吹气口2放入口中吹气,并自己观察推拉片5所在的刻度线的值,即是肺活量值。
