Description

视力保护器
技术领域
本实用新型涉及一种保健器材，尤其涉及一种视力保护器。
背景技术
小孩子在写字时，如果姿势不正确，容易导致视力下降，视力一旦被损坏很难恢复，终生都将受影响。
实用新型内容
为了使小孩在写字时保持正确的姿势，本实用新型提出了一种视力保护器，它由下巴托架、支撑架和滑轨组成；下巴托架下端与支撑架上部通过滑轨滑动连接；滑轨上设置有锁紧螺母。
本实用新型的有益技术效果是：可使孩子在阅读、写字时，眼睛与纸面的距离保持在安全距离，保护视力，避免近视。
附图说明
图1、本实用新型结构正视图；
图2、本实用新型结构侧视图；
图中：下巴托架1、支撑架2、滑轨3、锁紧螺母4。
具体实施方式
本实用新型的结构为：它由下巴托架1、支撑架2和滑轨3组成；下巴托架1下端与支撑架2上部通过滑轨3滑动连接；滑轨3上设置有锁紧螺母。使用时，将支撑架2立在桌面上，通过滑轨3调整下巴托架1的高度，使下巴托架1与桌面的距离保持在视力不受损害的距离以上，然后用锁紧螺母4将滑轨3锁死，使下巴托架1和支撑架2之间无法再滑动，孩子写字时，使孩子的头部始终处于下巴托架1的外侧，就能很好的起到防止近视的作用；但小孩子自觉性差，有时写累了就会不自觉的将头放到下巴托架1上，由于巴托架1的高度是预先调节好了的，也能使眼睛与纸面的距离在安全范围内。
