Abstract

本实用新型弧光镜,是一种供弧焊工作人员使用的劳保用品。其通过光谱分离及光路变换手段,克服原有技术产品焊接过程中需频繁摘戴的缺陷,可提高劳动效率。

Description

本实用新型,是一种供从事弧焊作业的工作人员配戴的劳保用品。
电焊弧光,光亮度高,含丰富的紫外线成份,为防止弧光灼伤人眼,现有技术是采用各型滤色镜片。但型号小的滤色镜片,不能有效地保护人眼;型号大些的,光透射率低,焊接时,一旦弧光熄灭,透过滤色镜片,人眼就看不到任何物件,焊接过程中需不断地摘戴滤色镜,使用极为不便。
本实用新型的目的,是克服现有弧光滤色镜在弧光熄灭后不能视物,需频繁摘戴的缺陷,更有效地保护人眼,提高劳动效率。
具体实施方案如下:
一、设计构思
红光不破坏人眼的暗视觉。用类似于彩色摄象机红、绿、蓝三色分象方式获得由红光构成的单色景物象,成象于人眼视网膜。结构上保证人眼不直视弧光,充分避开紫外线的伤害。
二、整体结构
由防尘取景片、分光镜和镜筒等组成。
下面就本实用新型的一实施例的侧剖面图图1,进行详细说明。
1.防尘取景片(1):是一组透光玻片,使外界景物光进入镜筒(2),具有防止灰尘、焊渣进入镜筒(2)内等功能。
2.分光镜:是附有多层反射膜(5)的具一定几何形状的玻璃体,能把外界景物光,分离出具有一定波长范围的红光,改变传播方向后入人眼达视网膜。分离出的红光波长范围大小,取决于反射膜(5)层数、厚度。
3.镜筒(2):由硬质遮光材料构成,呈“L”状或呈“Z”状等非直筒形状。
另外,为修正入眼光线的频谱,可加装光色校正片(6);为防止镜筒(2)内光的散射,镜筒内壁附黑色软质衬层材料(3);从结构上保证防尘取景片(1)易于更换。
说明书附图的图1中,分光镜选用了棱镜型分光镜,其光路图如附图中图2所示。此外,分光镜还可以是其它几何形状,如片状等。
本实用新型,由于采用分光成象法,焊接过程中,不需频繁摘戴,可提高劳动效率。
说明书附图注解如下:
1.防尘取景片        2.镜    筒
3.衬层材料        4.玻璃体
5.反射膜        6.光色校正片

Claims (1)
