The utility model relates to the teaching device technical field, in particular to an overweight weightlessness visual instrument for teaching. With the teaching of overweight and weightlessness visual instrument, mounted on the bracket with the pull bracket are mounted at the top end of the beam, a ruler shows the number of fixed beam, the beam is arranged on the upper surface of two parallel fixed pulley distribution, pull around two fixed pulleys are installed on both ends of the pull line, hook, lateral pull out after the hanging bracket is provided with a first end weight, on the other end of the pull wire is connected with the pull down through the spring, drop fixed line laser generator, the bottom line is provided with second hanging drop weights; the laser generator is arranged at the left side of a plane mirror tilt angle to 45 degrees. The utility model has the advantages of simple structure, reasonable design, low cost, can make teachers in the classroom teaching of the principle of overweight and weightlessness, straightforward presentation to the students, so that students more easily understand the overweight and weightlessness.
【技术实现步骤摘要】
教学用超重失重可视仪
本技术涉及教学装置
,尤其是一种教学用超重失重可视仪。
技术介绍
失重和超重在现实社会中通过精密仪器来测试,由于其需要准确性,所以设备比较复杂,操作也非常繁琐;在学校为了教学过程目的而购买使用上述仪器,就会需要很大的开支,所以在学生课堂进行失重和超重教学时,基本采用语言去讲,让学生很难从实际中理解失重和超重的具体、直接的体会。
技术实现思路
本技术要解决的技术问题是:克服现有技术的不足,提供一种教学用超重失重可视仪。本技术解决其技术问题所采用的技术方案是:一种教学用超重失重可视仪,安装在支架上,具有上拉线,支架顶端安装有横梁,横梁上固定安装有示数标尺,横梁上表面安装有两个并列分布的定滑轮,上拉线绕在两个定滑轮上,上拉线两端均安装有挂钩,上拉线一端伸出支架外侧后挂设有第一砝码,上拉线另一端通过弹簧连接有下拉线,下拉线上固定安装有激光发生器,下拉线底部挂设有第二砝码;所述激光发生器左侧安装有倾斜角度为45°设置的平面镜,支架底部下表面设有便于超重失重可视仪移动的滚轮。进一步地,所述的下拉线通过吊环挂设在上拉线低端,吊环与弹簧固定连接。吊环挂设便于操 ...
