Abstract

本发明提供一种教学用力平衡演示器，教学使用的力平衡演示器在支架上方装有横向设置的条形支板，该条形支板两侧各有一个活动槽轮，两个活动槽轮之间装有可左右滑动的系绳，系绳两端设有悬挂配重物的挂钩，中间设有滑移标示牌。教学使用时，可通过配重物体在两个挂钩上悬挂，让系绳中间的滑移标示牌的左右滑移而显示等重或不等重。

Description

教学用力平衡演示器
技术领域
本发明涉及一种教学仪器，具体的说是一种教学用力平衡演示器。
背景技术
在中小学物理课中，要对物体的重量作平衡讲解，由于缺乏专用的力平衡演示装置，很难用语言全面表述不同比重物体的相互关系和作用，使学生无法全面了解力平衡的物理知识。
发明内容
本发明的目的在于提供一种教学用力平衡演示器，可通过相同比重或不同比重的物体的相互作用力而清晰的演示比重关系。
本发明包括系绳，所采用的技术方案在于：教学使用的力平衡演示器在支架上方装有横向设置的条形支板，该条形支板两侧各有一个活动槽轮，两个活动槽轮之间装有可左右滑动的系绳，系绳两端设有悬挂配重物的挂钩，中间设有滑移标示牌。
本发明具有如下优势效果：通过上述技术方案，由于采用一个可通过不同配重体让系绳左右滑移的演示装置，使用时，可在系绳两端的挂钩上悬挂一定重量的物体，即可通过两者比重的差异而通过系绳中间的滑移标示牌的左右移动而显示不同比重的力平衡，由此直观的演示力平衡可让学生对理论充分理解，解决了现在无专用演示仪器而不利讲解理解的问题，有利更好的配合物理课讲解。
附图说明
下面结合附图和实施例对本发明作进一步详述。
图1为本发明结构示意图。
具体实施方式
图1所示：教学使用的力平衡演示器在支架1上方装有横向设置的条形支板2，该条形支板2两侧各有一个活动槽轮3，两个活动槽轮3之间装有可左右滑动的系绳4，系绳4两端设有悬挂配重物的挂钩6，中间设有滑移标示牌5。
