Abstract
A welding mask comprises a welding cap, wherein an observation window with a mirror bracket is formed in the middle of the front end of the welding cap, and a transparent lens and an eye protection lens are arranged on the mirror bracket. The welding mask is characterized in that an automatic filter lens is arranged between the transparent lens and the eye protection lens. Compared with the prior art, the welding mask has the advantages that due to the fact that the automatic filter lens is arranged between the transparent lens and the eye protection lens, brightness of the welding mask can be automatically adjusted, so that the welding mask can flexibly adjust the brightness according to work requirements, more than 99.99% of infrared rays and ultraviolet rays can be blocked, and meanwhile the purposes of eye protecting and observing of welding seams though controllable brightness changes are achieved, the structure is simple, and the application range is wide.
Description
Technical field
This utility model relates to a kind of welding mask, relates in particular to a kind of welding mask that can automatic beam change.
Background technology
Welding mask can effectively prevent the strong arc light that produces in the weld job process to the injury of eye, and each harmful gas of the splash of appearance etc. causes infringement to face, reduces the generation of skin burn disease.Before the welding starting the arc; electric welder's helmet is to be in bright attitude; can observe clearly the position of weld seam to avoid the starting the arc blindly; and the moment of the starting the arc automatic light-changing electric-welding face guard control within the extremely short time that liquid crystal lens is dimmed to reach the needed brightness (this brightness can be regulated) of when welding; protected people's eyes not to be subjected to the injury of electro-welding arc; and can observe clearly whole welding process, guarantee welding quality, thereby improve speed of welding.After welding was finished, electric welder's helmet must return bright attitude and wait for next time welding, to avoid welding the twilight sunset of high temperature generation to the injury of eye.
Be a kind of welding helmet the Chinese utility model patent " a kind of welding helmet " of ZL201120105272.X (notification number is CN202051903U) has disclosed such as a patent No., transparent glasses lens and screening glass are installed on its mirror holder, and screening glass is arranged on the side on its top of transparent glasses lens.Adopt the welding helmet of this structure; although solved protective eye lens under when welding, handy hands was with its group; with hands its group got on when not welding; use inconvenient technical problem; but in actual use; can not automatically regulate the brightness of protective eye lens, brightness adjusting according to electric welder's job demand and voluntarily, and protection electric welder's eyes.
The utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of welding mask, can adjust flexibly welding mask needed brightness when welding when work, and is simple in structure.
This utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of welding mask, include weld cap, have the viewing window that mirror holder is installed in the middle of the described weld cap front end, transparent glasses lens and screening glass are installed on the described mirror holder, it is characterized in that: the automatic light-filting eyeglass is installed between described transparent glasses lens and the screening glass.
For realizing that the automatic light-filting eyeglass removably is connected on the mirror holder, described automatic light-filting eyeglass is installed on the described mirror holder by the demountable structure of filter box.
Further, the demountable structure of described filter box comprises the hold-down ring that is connected in respectively edge on the described mirror holder outer surface both sides and compresses described automatic light-filting eyeglass.
For strengthening removably connecting of described mirror holder and filter box, described mirror holder inner surface is formed with the draw-in groove that matches with described edge.
Compared with prior art; the utility model has the advantage of: because the automatic light-filting eyeglass being installed between transparent glasses lens and screening glass; can automatically regulate the brightness of welding mask; welding mask can be according to self job demand and is adjusted neatly brightness like this; can stop 99.99% above infrared ray and ultraviolet passing through; the purpose that reaches the protection human eye and well observe weld seam by controlled bright dark variation simultaneously, it is simple in structure, and is applied widely.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
The specific embodiment
Embodiment is described in further detail this utility model below in conjunction with accompanying drawing.
A kind of welding mask includes weld cap 1, has the viewing window that mirror holder 2 is installed in the middle of weld cap 1 front end, and transparent glasses lens 3 and screening glass 4 are installed on the mirror holder 2, between transparent glasses lens 3 and the screening glass 4 automatic light-filting eyeglass 5 is installed.This automatic light-filting eyeglass 5 is that the demountable structure by filter box 6 is installed on the mirror holder 2, its demountable structure comprises the hold-down ring 62 that is connected in respectively edge on the described mirror holder 2 outer surface both sides 61 and compresses automatic light-filting eyeglass 5, correspondingly, mirror holder 2 inner surfacies are formed with the draw-in groove 21 that matches with edge 61.
During installation, only the edge of filter box 6 need to be inserted the draw-in groove 21 in the mirror holder 2, and automatic light-filting eyeglass 5 is pressed in the filter box 6 by hold-down ring 62, and be installed between transparent glasses lens 3 and the screening glass 4.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment this utility model is had been described in detail, it will be understood by those of skill in the art that it still can make amendment to the technical scheme that aforementioned each embodiment puts down in writing, perhaps part technical characterictic is wherein replaced on an equal basis; And these modifications or replacement do not make the essence of appropriate technical solution break away from spirit and the scope of each embodiment technical scheme of this utility model.
