Description

头带式电焊防护面罩
本实用新型涉及一种电焊设备,尤其是一种头带式的电焊防护面罩。
目前所使用的电焊防护面罩,有手提式和头带式两种,但都存在着一定的缺点。例如:手提式的需一手拿焊枪,一手拿面罩,当焊件需固定时,很不方便。有些不熟练的电焊工由于怕焊点不准,未把面罩护到头上,便已将焊枪点到焊体上,容易被电弧光激伤。特别是在高空电焊作业时,手提式防护面罩更是不适用。而现有的头带式防护面罩由于带上头后看不见焊体的焊点,无法操作,因此在电焊作业中很少使用。
本实用新型的目的在于提供一种克服上述两种防护罩的缺点,使用方便,提高焊接工作效率和焊接质量的防护面罩。
本实用新型由防护罩主体、护目镜片、镜片框、控制阀、翻一起弹簧和网状头带圈等组成。
下面结合附图作详细说明。
图1是本实用新型的结构示意图。
在防护罩2上由外向里安装护目镜片框8,护目镜片通过镜片固定杆5和固定杆轴6和镜片框8联接,在镜片框8左侧安装控制阀9,通过翻起弹簧7与镜片3相联,可扣住和翻起镜片3。在护目镜片3上开一个0.8毫米的嘹望孔4,可观察焊点。网状头带圈1固定在防护罩2的两侧。
采用本实用新型不必手拿,可戴在头上,由于护目镜片上开有嘹望孔看清焊点,护目镜片可扣住或翻起随时观察焊接情况。

Claims (2)
