Abstract

一种新型焊接面罩,包括有面板,观察窗铁框,滤光玻璃,盒状固定件,支持件等构成。其滤光玻璃紧裹在盒状固定件内,固定件紧扣在观察窗铁框和面板间,组成一个滤光玻璃不易振碎的抗振焊接面罩。

Description

本实用新型涉及一种保护面部和眼睛的焊接面罩。
目前使用的各种焊接面罩,一般由面板、观察窗铁框、滤光玻璃固定片、支持件等组成。它们共同的特点,是在焊接工作中,能有效地隔绝电焊光对焊接者面部和眼睛的伤害。但现有焊接面罩有一个共同的缺点,就是其滤光玻璃在使用中易被振碎。
本实用新型的目的是提供一种具有抗振能力的焊接面罩。
本实用新型的目的是这样实现的:在观察窗铁框与面板孔中间的滤光玻璃四边,紧裹住一个顶部敞开、底部开孔的盒状固定件,固定件内侧凸台阶与盒底边框之间为滤光玻璃,固定件外侧凸台扣在面板上组成一个焊接面罩。
本实用新型由于其滤光玻璃被固定件裹得紧紧的,依靠固定件的封闭和缓冲作用,滤光玻璃在使用中不会被振碎。
实用新型的具体结构由以下实例及其附图绘出:
图1,是新型焊接面罩外型图;
图2,是观察窗顶视剖视图;
下面结合附图详细说明依据实用新型提出的具体的焊接面罩结构    该焊接面罩包括有面板1、观察窗铁框2、滤光玻璃3、盒状固定件4、支持件5,等构成。
面板1与观察窗铁框2采用铆钉等方式连成一体,在面板1与观察窗铁框2内有一个顶部敞开,底部开孔的盒状固定件4,固定件4的内侧有凸台阶6,其凸台阶6与盒底边框7紧紧裹住滤光玻璃。
固定件的外侧有凸台阶8,凸台阶8紧扣住面板1而被固定在观察窗铁框2内,从而构成一个具有抗振能力的新型焊接面罩。

Claims (3)

1、一种新型焊接面罩,包括有面板,观察窗铁框,滤光玻璃,盒状固定件,支持件等装置,其特征在于:
盒状固定件为一顶部敞开,底部有孔的盒状固定件。
2、根据权利要求1,所述的焊接面罩,具特征是盒状固定件包括有内侧四壁上的凸台阶,外侧壁上的凸台阶。
3、根据权利要求1,所述的焊接面罩,其特征是盒状固定件内侧凸台阶与盒底四框间有滤光玻璃。
