Abstract

The utility model relates to a welding optics and face mask with small holes, which is glasses and face mask used under welding and similar situations for protecting eyes and facilitating observation. 3-5 small holes with aperture of 1-2 mm and hole-pitch of 5 plus or minus 1 mm are respectively drilled on the protective lens that are embedded on the frame and face mask and directly facing two eyes; and plain glass spectacles are disposed above the protective lens. Before welding, the welders can clearly observe the welding part by looking straight forward through the small holes on the protective lens, when spark generates, rapidly and slightly raise head and continue looking at the welding part through the protective lens below the small holes to implement welding work, and after welding, implement other non-glare operation through the plain glass spectacles. When the light is dim, the welding part can be observed by the plain glass spectacles instead of the small holes. The utility model has advantages of simple structure, convenient production and usage, high working efficiency, and effectiveness for protecting eyes; and can be widely used for welding, metallurgy, experiment, polishing and other works with frequently changed glare and non-glare.

Description

Pinhole type Eye protector for welder, cover

Technical field this utility model relates to a kind of be used to protect order, the glasses of being convenient to observe, face shield under electric welding or other analogue.

The existing electric welding glasses of background technology, face shield, on mirror holder, cover body, be embedded with screening glass, because the screening glass light transmission is poor, need take away glasses or face shield before the welding, be certain about weld, during welding or put on one's glasses, or proficiency is held welding gun, hold face shield on the other hand and weld, take down glasses or face shield after having welded again, the welding situation is observed.Troublesome poeration, work efficiency are low, and the someone designs " a kind of moment self-regulated anti glare anti static coatings glasses " (patent No.〉89200462) for this reason, and it mainly is provided with the anti glare anti static coatings film above the pupil upper edge is the boundary.Meet that high light inclines slightly at any time that following sight line of lifting just can see through that high light is removed to block in top that eyeglass focuses on normal or dash forward and realize at any time that immediately moment self-regulated is more remarkable when vowing at high light in short-term." a kind of electronic glasses device of automatic protection electro-welding arc " (patent No. 00263619), the variation of the logical light quantity of electronic glasses eyeglass, be controlled by the variation of the electric welding electric current that passes through the CT induction coil, when the CT no current passes through, electronics eyeglass LCD is a light transmission state, then be light tight state when CT has electric current to pass through, its output connects current rectifying and wave filtering circuit." Spectacle " (patent No. 99203971), it is that fire escape mask is followed closely on safety helmet.On fire escape mask, inlay 2 plate plane glass lens, connect 2 two anti-filter lens for arc welding that can spin upside down around axle separately by axle at flat glass eyeglass top edge.When electric welding, a slice Eye protector for welder is wherein overturn up, another sheet filter lens for arc welding is screened before the flat glass eyeglass, when the electric welding sparking, those eyes that do not have filter lens for arc welding to screen are closed, observe with the another eyes.When stopping sparking, then observe with the eyes that do not have filter lens for arc welding to screen.

The summary of the invention the purpose of this utility model is at above-mentioned present situation, aim to provide a kind of simple in structure, can be widely used in the work of high lights such as electric welding, metallurgy, experiment, technology polishing, non-high light frequent variations, easy to use, high efficiency, weldering is preceding, postwelding need not take off pinhole type Eye protector for welder, the cover that can observe.

The implementation of this utility model purpose is that pinhole type Eye protector for welder, cover are embedded with screening glass 3 on mirror holder 2 or mask body 5, over against two places the aperture 4 that is no less than 2 is arranged on the screening glass 3, screening glass 3 top embedding zero diopter transparent glasses lens 1.

This utility model except that being embedded with screening glass 3, also is embedded with zero diopter transparent glasses lens 1 above screening glass 3 on the mirror holder 2 of used electric welding glasses, face shield, cover body 5.On the screening glass 3, be drilled with 3-5 aperture 4 over against two positions, hole diameter is 1-2mm, pitch of holes 5 ± 1mm.Before the welding,, utilize the pinhole imaging system principle to know and see and to be welded the position by aperture.Play arc-welding moment, rapidly head is slightly faced upward, the screening glass 3 that eyes see through the aperture below continues to keep an eye on by the weldering position, implements welding job.After having welded, carry out other non-high light operation by the zero diopter transparent mirror.Therefore, adopt this utility model welding front and back all need not take off one's spectacles or face shield.

When light is too dark, can passes through aperture, but watch by weldering position or observation welding situation by zero diopter transparent glasses lens 1.

This utility model is simple in structure, easy to make, cost is low, can be widely used in the work of high lights such as electric welding, metallurgy, experiment, technology polishing, non-high light frequent variations, and easy to use, high efficiency can effectively be protected eyes.

Specific embodiment this utility model on mirror holder, cover body embedding zero diopter transparent glasses lens 1, the screening glass 3 of aperture 4 is arranged.On the screening glass 3, be drilled with 3-5 aperture 4 over against two positions, hole diameter is 1-2mm, pitch of holes 5 ± 1mm.Before electric welding, see that by aperture postwelding is seen the welding situation from aperture or plano lens by the weldering position.

Claims (3)

1, pinhole type Eye protector for welder, cover are embedded with screening glass (3) on mirror holder (2) or mask body (5), it is characterized in that on the screening glass (3), and the aperture (4) that is no less than 2 is arranged over against two places, screening glass (3) top embedding zero diopter transparent glasses lens (1).
