Description

滑动黑板
                          技术领域
本实用新型涉及一种教学用黑板,尤其是一种滑动黑板。
                          背景技术
现有教学黑板多为固定的一块板面组成,由于反光原故坐在教室两边的学生看不见黑板另一端的内容,这给教学带来太多不便。
                          发明内容
本实用新型的目的就是要提供一种避免黑板反光使坐在教室任意位置的学生能看清板书内容的滑动黑板。
本实用新型的目的是这样实现的:一种滑动黑板,包括板面和外框1,板面由上板面2和下板面3组成,上板面2和下板面3分别由左板面4和右板面5组成,外框1上端设有滑轮支架6,滑轮7与滑轮支架6连接,上板面2和下板面3通过滑绳8与滑轮7连接,外框1上下端分别设有滑槽9,左板面4和右板面5与滑槽9滑动连接。
本实用新型由于采用上述结构,将板面分为上板面2和下板面3,外框1上端设置滑轮支架6,滑轮7与滑轮支架6连接,上板面2和下板面3通过滑绳8与滑轮7连接,从而实现上板面2和下板面3上下滑动,将上板面2和下板面3分为左板面4和右板面5,使左板面4和右板面5与滑槽9滑动连接,从而实现左板面4和右板面5左右滑动,避免黑板反光,使坐在教室任一位置的学生都能看清板书内容。
                          附图说明
下面结合附图和具体实施方式作进一步说明。
图1是本实用新型的结构示意图。
                        具体实施方式
本实用新型的结构包括板面和外框1,板面由上板面2和下板面3组成,上板面2和下板面3分别由左板面4和右板面5组成,外框1上端设有滑轮支架6,滑轮7与滑轮支架6连接,上板面2和下板面3通过滑绳8与滑轮7连接,外框1上下端分别设有滑槽9,左板面4和右板面5与滑槽9滑动连接。
教学时教师可通过滑轮7任意调整上板面2、下板面3、左板面4、右板面5,使坐在教室任意位置的学生都能看清板书内容,方便教学。
