技术领域
本发明涉及物理教学领域,具体地说是一种滑轮实验装置。
背景技术
物理教学中,滑轮的教学占有很大的比例,其中动滑轮、定滑轮及其组合的特性理解经常要反复的讲解才能理解,同时用于教学的滑轮实验教具也多种多样,但多存在钢丝绳缠绕滑轮时易缠绕在一起等不利因素,影响了教学效率,且在多种滑轮组合实验时要提供较多数量的动、定滑轮,安装非常不便。
发明内容
为解决上述问题,本发明提供了一种滑轮实验装置,能够快速、直观的组装出各种不同组合的滑轮组,用于教学实验演示。
本发明是这样实现的:底座上设置两个立柱,立柱内侧中部设置有滑道,立柱上部安装压力感应器,压力感应器与安装在立柱外侧的显示器连接,定轴安装在立柱上部的压力感应器上,定轴外安装定辊筒,定辊筒上套有套圈,动轴安装在立柱内侧的滑道内,并能够沿滑道上下移动,动轴外安装动辊筒,动轴上下分别设置提升杆和连杆,提升杆和连杆分别和提升环和载物盘连接。
本发明的有益效果是:结构简单,原理科学,在进行动滑轮、定滑轮及组合演示实验时不受动、定滑轮的个数限制,可随意的进行组合。
附图说明
下面结合附图作进一步说明。
图1是本发明的结构示意图。
