Abstract
The invention discloses a multifunctional welding mask, which comprises a mask main body, a head strap and a face protection plate, wherein a sliding gear rack for regulating the size of the head strap is arranged on the head strap; the face protection plate is rotatably connected to the mask main body; a viewing window which is movably connected to the face protection plate is formed in the face protection plate; a transparent plate, a variable light screen provided with a variable color light filter, and a protective film are sequentially arranged on the viewing window from inside to outside; the transparent plate is movably connected to the variable light screen; the variable light screen is used for filtering light by virtue of the variable color light filter; the transparent plate is used for protecting eyes when the variable light screen is opened; and the protective film is used for protecting the variable light screen. The welding mask disclosed by the invention is directly covered on the head; it is unnecessary for an operator to take down the welding mask to confirm a welded part, so as to thoroughly free two hands; and the welding mask is also capable of effectively protecting neck and ears, so as to avoid harm due to electromagnetic radiation and thermal radiation.
Description
Technical field
The present invention relates to welding auxiliary facilities, particularly relate to a kind of Mobyneb electric welder's helmet.
Background technology
Usually; protecting eyes in order in harmful ultraviolet, strong visible light and the infrared ray that produce from arc welding or gas welding and when cutting off mother metal work, also using welding mask to protect the face of worker from welding arc light and the burn caused due to thermal conductance or the burn danger that causes due to the fragment of the material through heating etc.
Early stage electric welder's helmet adopts the glass filter of a fixing color number as observation window during welding, when there is no electro-welding arc, remove whole face shield or observation window, after being ready to, face shield or observation window are resetted, then electric welding is started, this kind of mask body is formed by opaque material, welding job can only be confirmed by dark slide, and dark slide is colored as dark color to block various harmful light, be difficult to confirm outside under the state wearing welding mask, therefore, when welding job, the moment is needed to take welding mask to confirm welding position, very inconvenient, and this welding mask is covered with blind weldering, can not the shortcoming such as thorough liberation both hands.
In addition, the lens set part of existing common protective eye lens adopts two sheet glass to form mostly, and skin is made up of white clear glass, for stopping the splashes such as welding slag; Internal layer adopts the black glass that light transmittance is very low, for blocking dazzling arclight.In use there is following drawback in this protective eye lens:
1) play forearc, operator transmitting lens group can not observe welding position, causes arcing point inaccurate.
2) mode that the filter glass eyeglass employing that common face shield uses absorbs has carried out the filtration to infrared/ultraviolet, inevitable formation secondary radiation etc., thus the visual fatigue etc. making optic nerve impaired and cause, have impact on greatly and the observation of welding pool controlled and the formation of good weld seam.
3) darkness of traditional defense face shield only has limited several, and can not provide the best observation darkness of operator, have impact on the observation of operator to welding pool equally, the level that thus have impact on welding practitioner from many aspects plays.
At present, occur that again a kind of LCD of employing or LCD and filter set cooperation are the electric welder's helmet welding observation window, it is low color number when there is no arclight, user can be observed through observation window, and during electric welding, electric welder's helmet accepts arclight signal or electromagnetic signal, LCD is driven to become light, become high color number, now can be observed the operation of electric welding by observation window, effect is better; But due to the restriction of the reasons such as the cost of LCD, characteristic and weight, its observation window is mostly less, brings inconvenience to user.
In addition, usually the greatest problem run in welder's welding process in the winter time----outside air temperature differs larger with characteristics of contaminated respiratory droplets gas temperature, the gas of characteristics of contaminated respiratory droplets is upwards fled, run into ice-cold protective eye lens and just solidify formation mist, affect the visual field to observe, affect speed of welding and welding quality to the greatest extent.Current electric welder's helmet does not have anti-fog function, needs a hands to grip, be inconvenient to work when working in addition.
Summary of the invention
Technical problem to be solved by this invention is how to overcome existing electric welder's helmet.
In order to solve the problems of the technologies described above, the invention provides a kind of Mobyneb electric welder's helmet, comprise mask body, headband and facial baffle, described headband has the slidably tooth bar for adjusting headband size, described facial baffle and described mask body are rotationally connected, described facial baffle is provided with the observation window be flexibly connected with facial baffle, described observation window is disposed with lamella lucida from inside to outside, there is change optical screen and the protecting film of variable color optical filter, described lamella lucida and change optical screen are flexibly connected, described change optical screen is used for being filtered by variable color optical filter, described lamella lucida is used for the protection eye when becoming optical screen and being opened, described protecting film is for the protection of change optical screen.
Further, described face shield also comprises the angle adapter be connected with observation window, and described angle adapter is for regulating the angle of observation window.
Further, described face shield also comprises the breathing vent be arranged on facial baffle, and described breathing vent is fixed on observation window bottom and for discharging the gas in face shield.
Further, described breathing vent is set to the breach of nose shape.
Further, described change optical screen comprises substrate, photosensitive material layer and transparency electrode successively, and described photosensitive material layer is formed in substrate, and described transparency electrode is drawn by photosensitive material layer.
Further, described substrate is glass or transparent membrane.
Further, described photosensitive material layer can regulate change arbitrarily between the complete pellucidity of transmittance >75% and the non-fully pellucidity of transmittance <75%.
Further, described mask body is also provided with adjusting knob, described adjusting knob has two gears, and each gear respectively correspondence is opened change optical screen and opened lamella lucida.
Further, described mask body is also provided with locking press button, presses described button and facial baffle can be locked in state upwards.
