Abstract

本实用新型涉及一种教学仪器,尤其是涉及一种物理教学实验用的带磁铁的杠杆。本实用新型是在杠杆(1)上连有一磁铁(2),且磁铁(2)与杠杆(1)之间为铰连接。目前的黑板一般用铁皮制成,实验时可以通过磁铁(2)把杠杆(1)固定在黑板上,使杠杆(1)可以自由转动。这样不仅做实验方便,而且还能让所有的学生都能观察得到。

Description

带磁铁的杠杆
所属技术领域
本实用新型涉及一种教学仪器,尤其是涉及一种物理教学实验用的带磁铁的杠杆。
背景技术
目前实验用的杠杆虽然很多,但还没有一种可以固定在黑板上进行做实验的杠杆。
发明内容
本实用新型的目的是提供一种这样的带磁铁的杠杆,它可以很方便地固定在黑板上进行杠杆的演示实验。
本实用新型解决其技术问题所采用的技术方案是:在一杠杆上连有一磁铁。本实用新型的有益效果是:由于采用了上述方案,人们在做杠杆的演示实验时,就可以很方便地把杠杆固定在黑板上进行做实验。这样不仅做实验方便,而且还能让所有的学生都能观察得到。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图中所示的是本实用新型的结构示意图;
图中1、杠杆,2、磁铁。
具体实施方式
如图所示,本实用新型是在杠杆(1)上连有一磁铁(2),且磁铁(2)与杠杆(1)之间为铰连接。目前的黑板一般用铁皮制成,实验时可以通过磁铁(2)把杠杆(1)固定在黑板上,使杠杆(1)可以自由转动。
