Abstract

The utility model relates to the structure of an eye protecting mask for electric weld, which comprises a mask body with a mask nose outward protruded. The mask body is provided with an eye holes whose outer parts are covered with eye protecting lenses which can vertically move. The two sides of the mask body are provided with fastening belts and the mask body can also be provided with an opening hole whose outer part is covered with opening plates which can vertically move. The eye protecting mask for electric weld can be worn on the head without hand hold in use. Thus the fine arc weld of hand hold, the climbing weld joint and the overhead weld can be conducted. The utility model also has the advantage of large visual field and the lenses of the eye protecting glasses are uneasy to be burnt.

Description

The order mask is protected in electric welding

The structure that the order mask relates to welders' mask is protected in electric welding.

At present, the safety visor that uses of welder, comprise a cover body, on cover body, be fixed with protective eye lens, be fixed with handgrip in the lower end of cover body.This traditional safety visor, the welder wants a hand-held safety visor, another hand torch welding, its weak point is: 1, not being suitable for need be with hand steered meticulous arc-welding of holding, climb up by holding on to operating types such as welding and overhead welding; 2, because welder's the eyes and the distance of protective eye lens, thereby the visual field is little, and in order to guarantee welding quality, human body must be near the welding position, easily the burn eyeglass of protective eye lens of the spark when this just makes welding, reduction definition.

The order mask is protected in the electric welding that need not hand when the purpose of this utility model is a kind of welding of design.

This electric welding is protected the order mask and is comprised the mask body, its construction features is that the mask body has the face nose of evagination and be provided with eyelet above the face nose, eyelet is coated with the screening glass that can move up and down outward, and screening glass is contained on the mask body, is provided with restraint zone in the both sides of mask body.

The order mask is protected in this electric welding, can also be provided with oral pore at the face nasal downside of mask body, and oral pore is coated with the mouth protective piece that can move up and down outward, and mouth protective piece is contained on the mask body.

During use, to tighten band and be solidly set on head, following restraint zone is solidly set on cervical region, only need to take welding gun just can weld, do not need use the another face shield, thereby can hand meticulous arc-welding, climb up by holding on to and weld and weld in the overhead position workpiece with a hands, because the distance of eyes and protective eye lens is near, the visual field is big, and the distance of human body and welding position not BITAI is near, be difficult for the burning eyeglass of protective eye lens of the spark during welding.In the time need observing welding quality and observe extraneous situation with eyes, only need and will move on the screening glass or move down, expose eyelet and get final product, when needs are talked with others, will move on the mouth protective piece or move down, expose oral pore and get final product, very convenient.

Accompanying drawing shows the embodiment that the order mask is protected in electric welding, and wherein Fig. 1 is that electric welding is protected the order mask at the front view in when welding, and Fig. 2 is that electric welding is protected the order mask and is in not welded condition, the structural representation when observing and talking with others with eyes, and Fig. 3 is the A-A cutaway view of Fig. 1.

In the present embodiment, electric welding is protected the order mask and is comprised mask body 1, mask body 1 has the face nose 2 of evagination, and above face nose 2, be provided with eyelet 3, face nose 2 belows are provided with oral pore 7, the eyelet 3 outer screening glasses 4 that are coated with, screening glass 4 usefulness are with the elastic order frenulum 5 that protects to be installed on the mask body 1, the oral pore 7 outer mouth protective pieces 8 that are coated with, mouth protective piece 8 usefulness are with the elastic mouthful frenulum 9 that protects to be installed on the mask body 1, owing to protect order frenulum 5 and protect mouthful frenulum 9 and have elasticity, thereby screening glass and mouth protective piece can be moved up and down, be provided with in the both sides of mask body 1, following two restraint zones 6.
