Abstract
The utility model relates to the technique field of face shields, especially a filter box, which comprises a filter and a white glass slide. A liquid crystal sheet is arranged between the filter and the white glass slide. Polarizers clung to the two sides of the liquid crystal sheet are also clung to the filter and the white glass slide. The filter box is simple in structure and the liquid crystal layer of the filter box is also simple in structure. The material of the filter box is environment-friendly and energy-saving. Due to the adoption of the filter box, infrared rays and ultraviolet rays in the electric arc light are completely removed and the visual fatigue during the operation process is relieved. Meanwhile, troubles bake at home in the ocular protection filed of welders are avoided and the full play of the skills of welders is also ensured.
Description
Technical field
This utility model relates to a kind of eyeglass, relates in particular to a kind of optical filtering mirror case.
Background technology
At present; Face shield to be worn during known welding assembly in case arc light injury eyes and face; The eye-protecting optical filter that face shield is commonly used is commonly called as filter glass; Be difficult to see through filter glass during the not starting the arc and observe the position that is soldered, hand-held face shield commonly used and wear-type face shield bring inconvenience to striking slag behind the arc, also need a hands to take face shield on the handle though the protective eye lens of hand-held face shield keying button is arranged on; Though wear-type face shield protective eye lens open-close on-off is arranged on the electrode holders bakelite handle, needs the automatic open close device to accomplish protective eye lens and open and close.The glass that uses on the face shield is filter glass; Filter glass adopts the glass of fixing color number; The eye protection ability is equal to the darkness of front glass, has accidental exposure and secondary radiation in the moment of the starting the arc, is prone to cause visual fatigue; Be engaged in weld job for a long time and be prone to cause vision decline, even cause the eye occupation disease.
Summary of the invention
The technical problem that this utility model will solve is: the glass that uses on the face shield is filter glass; Filter glass adopts the glass of fixing color number, and the eye protection ability is equal to the darkness of front glass, has accidental exposure and secondary radiation in the moment of the starting the arc; Be prone to cause visual fatigue; Be engaged in weld job for a long time and be prone to cause vision decline, even cause the eye occupation disease, a kind of optical filtering mirror case is provided.
In order to overcome the defective that exists in the background technology; This utility model solves the technical scheme that its technical problem adopted: this utility model comprises optical filter and white slide; Be provided with polaroid and liquid crystal layer between said optical filter and the white slide; Said polaroid is close to optical filter, and said polaroid directly is provided with liquid crystal layer, is provided with liquid crystal layer between said polaroid and the white slide.
The beneficial effect of this utility model is: this optical filtering mirror case of this utility model is simple in structure; Liquid crystal layer is simple in structure; Material environment friendly and energy-conservation, this optical filtering mirror case have thoroughly been removed infrared ray and the ultraviolet in the arclight, have alleviated the visual fatigue in operating process; Both remove the trouble and worry of welder aspect eye protection, ensured giving full play to of welder's technical ability again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the structural representation of this utility model;
Wherein: 1, optical filter, 2, polaroid, 3, liquid crystal layer, 4, white slide.
The specific embodiment
As depicted in figs. 1 and 2; Comprise optical filter 1 and white slide 4 among the figure, be provided with polaroid 2 and liquid crystal layer 3 between said optical filter 1 and the white slide 4, said polaroid 2 is close to optical filter 1; Said polaroid 2 directly is provided with liquid crystal layer 3, is provided with liquid crystal layer 3 between said polaroid 2 and the white slide 4.Overall structure is simple; Liquid crystal layer is simple in structure; Infrared ray and the ultraviolet in the arclight thoroughly removed in glass and liquid crystal material environmental protection and energy-conservation, this optical filtering mirror case, alleviated the visual fatigue in operating process; Both remove the trouble and worry of welder aspect eye protection, ensured giving full play to of welder's technical ability again.
Said liquid crystal layer 3 is made up of glass and liquid crystal.Liquid crystal layer is simple in structure, and infrared ray and the ultraviolet in the arclight thoroughly removed in glass and liquid crystal material environmental protection and energy-conservation, alleviated the visual fatigue in operating process.
This optical filtering mirror case of this utility model is simple in structure; Liquid crystal layer is simple in structure; Material environment friendly and energy-conservation, this optical filtering mirror case have thoroughly been removed infrared ray and the ultraviolet in the arclight, have alleviated the visual fatigue in operating process; Both remove the trouble and worry of welder aspect eye protection, ensured giving full play to of welder's technical ability again.
