More particularly, the present invention relates to an anti-fogging window for a welding helmet, which protects an operator's eyes during a welding operation and, in a welding helmet, The present invention relates to an anti-glare window for a welding helmet, which can be easily replaced when a welding filter and a cover plate are damaged by a spatter or an impact.

In general, welding helmets are used to protect the eyes and face when welding or cutting. An anti-glare device (hereinafter referred to as "cartridge") is fixedly mounted on the welding helmet to protect the user's eyes from intense harmful light generated when welding or cutting work is performed. Such cartridges typically shield light below 780 nm (IB) and below 365 nm (UV) and control the transmission of visible light so that the welding position can be visually confirmed without glare.

As shown in Fig. 1, the conventional welding helmet has a cut-off light switching device of a welding helmet of Korean Utility Model Registration No. 0166304, wherein a transparent portion 2 is formed in front of a welding helmet body 1, (1), wherein a helmet (3) and a shield (4) are provided in the helmet body (1) A pair of turning levers 8 are provided on the inner side of the supporting frame 6 and the turning lever 8 is provided on the outside of the supporting frame 6, Are connected to a support 9 provided in the helmet body 1 and provided with a double bib 10 at the lower end thereof and the support 9 is fixed to the inside of the upper part of the helmet body 1 by a spring 11 as shown in FIG.

Since the welding light source of the welding helmet can be accurately positioned at the welding position during the initial welding operation due to the opening and closing of the shielding gauge while freely moving both hands of the operator, It has the effect of protecting the eyes.

However, it is not easy to separate the protection gauge and the protection gauge in case of breakage due to the spatter and the impact, and a gap is formed between the gauge and the safety gauge, It is not possible to accurately read the welded portion due to the occurrence of blind spots on the safety glass, resulting in a problem that the work efficiency is lowered.

Korean Utility Model Registration No. 0166304.

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a welding helmet which can be easily replaced when a welding filter installed in a penetrating portion of a welding helmet is damaged by an impact and a spatter, Which can prevent the welding filter and the cover flame from being generated in the welding helmet according to the present invention.

In order to accomplish the above object, the present invention provides a welding prevention helmet according to the first aspect of the present invention, wherein a shielding window is formed in front of the helmet body for welding, and a protective window for protecting the eyes during welding is provided in the shielding portion, A welding filter installed on the inner side of the transparent portion of the helmet body to protect the eyes from harmful light, shock, and spatter generated during welding; A welding portion is formed on an outer circumferential surface on one side so as to be closely fixed to the inner circumferential surface of the welding filter, and is tightly coupled to the welding filter, a penetrating window is formed in the center portion so that the outside can be seen through the welding filter, Cover play that is coated with anti-fogging material to prevent blur caused by temperature difference And it is achieved by the anti-mist window for welding helmet, characterized in that made include.

In addition, the adhesive portion of the cover plate is formed of Velcro tape, and the Velcro tape is provided on the surface of the welding filter corresponding to the Velcro tape of the cover plate.

In addition, a coupling protrusion protruding from one end of the adhesive portion of the cover plate is formed, and a coupling groove is formed in a surface portion of the welding filter so as to be able to engage with the coupling protrusion of the cover plate. And a rubber packing part is provided.

As described above, in the present invention, the welding stopper for the welding helmet is configured such that the welding filter and the cover plate attached to the opening of the welding helmet are detachably attached to each other, and can be easily replaced when the welding helmet is broken by the impact and the spatter, The gap between the welding filter and the cover plate can be sealed without any gap, and the occurrence of the scorching on the back surface of the cover plate and the back surface of the welding filter can be prevented by the temperature difference inside and the wearer's work, There is an effect that can be.
