Description

折射式后视镜
技术领域
本实用新型公开一种折射式后视镜,涉及光学领域。 
背景技术
现有车船用后视镜一般是侧后视镜和内后视镜,其共同缺点都有因车辆或船只自身的遮蔽而有一定视野盲区,对行驶安全造成一定负面影响。 
日常需要倒走时,也因不能看到身后方的障碍物而容易摔倒。 
实用新型内容
本实用新型要解决的技术问题在于利用反射与折射等光学原理,来观察后方。 
本实用新型由凹形反射镜1、折射三棱镜2、凹透镜3、避光筒4组成,其中反射镜1在避光筒4前端、折射三棱镜2位于避光筒4中端、凹透镜3位于避光筒4后端,避光筒4在折射三棱镜2处向内呈弯曲状。 
为扩大视角和灵活度,折射三棱镜2、凹透镜3可以为一个或多个。 
本实用新型有益效果如下: 
1、本实用新型解决了车船或人倒走时宽角度后视的问题,提高安全系数。 
2、本实用新型结构简单直观,易使用。 
下面结合附图和具体实施方式对本实用新型做进一步详细说明: 
附图说明
例图为本实用新型的结构图。 
具体实施方式
例图为本实用新型的结构图,本实用新型由凹形反射镜1、折射三棱镜2、凹透镜3、避光筒4组成,其中反射镜1在避光筒4前端、折射三棱镜2位于避光筒4中端、凹透镜3位于避光筒4后端,避光筒4在折射三棱镜2处呈弯曲状。 
为扩大视角和灵活度,折射三棱镜2、凹透镜3可以为一个或多个。 
使用时将本实用新型固定在车顶的前上方或两侧,头戴使用可将其安装在帽子或头盔的上方或两侧,凹形反射镜1面对使用人,凹透镜3面对后方,再调整折射三棱镜2,达到最佳状态后,就可在凹形反射镜1中宽角度观察后方。
