Abstract

本实用新型涉及一种新式黑板,在黑板顶边安装一排照明灯;在黑板顶边开设滑道,连接杆顶端插入滑道连接,连接杆另一端连接放大镜。本实用新型具有结构合理、使用方便、功能齐全等优点。

Description

新式黑板
技术领域
本实用新型涉及一种教学用具,尤其是一种具有照明、放大字迹的黑板。
技术背景  目前,黑板是教学工作中最重要的工具之一。但是现在的黑板功能简单,只提供书写功能,却无法对粉笔字迹进行放大,对于坐在远处的同学来说,一旦字迹过小,他们无法清楚的看见黑板字迹,影响学习;另外,黑板只能在光亮环境下使用,受局限性较大。为此,提供一种多功能黑板解决上述问题。
发明内容
本实用新型的目的是提供一种新式黑板,用于解决普通黑板功能简单的问题。
为达到上述目的,本实用新型新式黑板,包括长方形黑板,在黑板顶边安装一排照明灯;在黑板顶边开设滑道,连接杆顶端插入滑道连接,连接杆另一端连接放大镜。
采用上述结构后,在黑板上左右滑动连接杆,通过放大镜放大黑板字迹,提供良好的观察效果;在光线暗淡时,使用者还可闭合照明电路的控制开关,通过照明灯发光提供照明。
本实用新型的优点是:结构合理、使用方便、功能齐全、工艺简单,可发挥照明、放大等功能,提供舒适便捷的教学条件。
附图说明
图1为本实用新型新式黑板的整体结构示意图。
具体实施方式
如图1所示,本实用新型新式黑板,包括长方形黑板1,在黑板1顶边安装一排照明灯2;在黑板1顶边开设滑道,连接杆3顶端插入滑道连接,连接杆3另一端连接放大镜4。
