Abstract

一种数学教学用课本放置支撑托架,涉及教学辅助用具技术领域,它包括“L”形支撑板(1)、连接板(2)、吸盘(3)、“U”形支架(4)、滑套(5)、弹性带(6),其特征在于“L”形支撑板(1)上端中部固定着连接板(2),连接板(2)上端底面转动连接着吸盘(3);“L”形支撑板(1)左右两端端面上分别固定连接着相互对称的“U”形支架(4),两个“U”形支架(4)上面分别设有相互对称的滑套(5),两个滑套(5)之间连有弹性带(6)。它结构简单,使用方便,能对课本进行有效支撑和固定,便于老师有更多的精力去绘图或书写,既减轻了老师的劳动强度,又提高了老师的教学效率。

Description

数学教学用课本放置支撑托架
技术领域:本实用新型涉及教学辅助用具技术领域,具体地说是一种数学教学用课本放置支撑托架。
背景技术:在数学教学课堂中,需要老师经常在黑板上书写公式和绘图,在绘图时老师通常将课本放置在讲桌上,然后拿起绘图工具在黑板上进行绘图,在绘图过程中要不断的转身回头查看课本上的内容,这样操作麻烦,费时费力,老师容易感到疲劳,给教学工作带来极大不便。
发明内容:本实用新型的目的在于克服上述不足,提供一种结构简单,使用方便,能对课本进行有效支撑和固定,便于老师在黑板上进行书写公式或绘图的数学教学用课本放置支撑托架。
本实用新型的目的是这样实现的:该数学教学用课本放置支撑托架包括“L”形支撑板、连接板、吸盘、“U”形支架、滑套、弹性带,“L”形支撑板上端中部固定着连接板,连接板上端底面转动连接着吸盘;“L”形支撑板左右两端端面上分别固定连接着相互对称的“U”形支架,两个“U”形支架上面分别设有相互对称的滑套,两个滑套之间连有弹性带。
使用时,首先通过吸盘将该装置吸附固定在黑板上,然后再将课本放置在“L”形支撑板上并用弹性带将打开的书页夹持固定即可,弹性带可根据需要随同滑套上下移动。
本实用新型的优点:结构简单,使用方便,能对课本进行有效支撑和固定,便于老师有更多的精力去绘图或书写,既减轻了老师的劳动强度,又提高了老师的教学效率。
附图说明:图1为本实用新型的结构图。
具体实施方式:以下结合图1对本实用新型作进一步详细描述:该数学教学用课本放置支撑托架包括“L”形支撑板1、连接板2、吸盘3、“U”形支架4、滑套5、弹性带6,“L”形支撑板1上端中部固定着连接板2,连接板2上端底面转动连接着吸盘3;“L”形支撑板1左右两端端面上分别固定连接着相互对称的“U”形支架4,两个“U”形支架4上面分别设有相互对称的滑套5,两个滑套5之间连有弹性带6。
