测距式眼镜架
本实用新型涉及一种让人们在读书、写字之时,使眼睛与书本之间保持正常距离(40cm)的装置,是一种保护视力的测距式眼镜架。
目前,公知的眼镜架,不具备使眼睛与书本之间保持正常距离的功能,当人们的读、写之时,在不自觉的情况下,经常发生眼部与书本之间距离缩短的情况,从而使眼睛快速疲劳,导至视力下降。
本实用新型的目的是提供一种测距式眼镜架,它能让人们在读书写字之时,使眼睛与书本之间保持正常距离。
本实用新型的目的是这样实现的:在左右两侧的镜腿前部各有一个突出的工型槽,使可以伸缩的、带凹型槽的测距尺,可以固定在镜架的左侧或右侧,当人们使用此镜架时,拉出伸缩尺就可以让人们在读写之时,使眼睛与书本之间始终保持正常的距离。
由于采用上述方案,既可以让人们在读写之时,使眼睛与书本之间保持正常距离,又便于人们日常携带。
下面结合附图和实例对本实用新型进一步说明。
图1是测距尺与眼镜架相衔接后,在使用状态下的本实用新型原理图。
图2是测距尺在收缩状态下的本实用新型。
图3是可以固定测距尺、带工形槽的眼镜腿正面图。
图4是眼镜腿的纵剖面图。
图5是完全伸出的测距尺。
图6是测距尺的纵剖面图。
在图1中,两侧的镜腿前端各有一个工型槽(2),以便测距尺(1)可任意安装在左侧或右侧,在读写之时,拉出测距尺(1)既可。
在图2中,读写完毕,既可收回测距尺(1)。
