Abstract
The utility model relates to an arc welding helmet, in particular to an arc welding helmet capable of automatically regulating light transmittance. The utility model discloses an automatic light regulating arc welding helmet, comprising a helmet and a front panel. The automatic light regulating arc welding helmet is characterized in that the front panel is fixedly provided with an eyepiece, a switch and a photo-sensor; the eyepiece comprises a front protection patch of the outer layer, a changing color patch of the middle layer and a back protection patch of the inner layer; the front protection patch and the back protection patch are clear glass, and the changing color patch is a liquid crystal material. The utility model has the following beneficial effects: it can regulate automatically the light transmittance, and have convenient use and high safety performance.
Description
(1) technical field under
This utility model relates to a kind of electric welder's helmet, the particularly a kind of electric welder's helmet that can regulate light transmittance automatically.
(2) background technology
Existing electric welder's helmet, in order to prevent electric welding light transmission eyepiece, the light transmittance of eyepiece is very low.Before electric welding, face shield need be taken away, just can see electric welding thing and welding rod clearly, during electric welding, rapidly face shield is moved.Operation is very inconvenient, and to the abecedarian, electric welding light is easy to perforating.
(3) summary of the invention
This utility model provides a kind of electric welder's helmet that can regulate light transmittance automatically in order to overcome the deficiency of above technology.
This utility model is realized by following measure:
The utility model discloses a kind of electric welder's helmet with an automatic light meter, form by the helmet and panel, its special feature is: be fixed with eyepiece, switch and optical sensor on the panel, described eyepiece is made up of protective sheet, the variable color sheet in intermediate layer and the back protective sheet of internal layer before outer field, preceding protective sheet and back protective sheet are clear glass, and the variable color sheet is a liquid crystal material.
Principle of the present utility model is: the variable color sheet that this utility model uses is liquid crystal material, is optical grating construction.By certain control grating is arranged in parallel or arranged vertical.When grating was arranged in parallel, light can see through, its transmitance height; When the grating arranged vertical, light penetration is very low.The variable color sheet is connected with optical sensor, control circuit, battery, switch, and optical sensor can be experienced light intensity, when light intensity reaches setting value, the control circuit action, make grating carry out arranged vertical, light transmittance is reduced, realize regulating automatically the purpose of light transmittance.
When light was available light, the variable color sheet in the face shield eyepiece presented the light transmittance under the naturalness, and user can see through eyepiece and see the workpiece form clearly; When electric arc ignited, optical sensor changes light delivered to control circuit, makes the action of variable color sheet by control circuit, and moment is reduced the logical light rate of variable color sheet, reaches the purpose that protection user eyes are exempted from the injury of electric arc high light; After electric arc disappeared, the light sensing was controlled by circuit, and the variable color sheet is returned to normal, and user need not be removed face shield can observe the welding situation.
The beneficial effects of the utility model are, can regulate light transmittance automatically, have easy to use, the security performance height.
(4) description of drawings
Fig. 1 is a surface structure sketch map of the present utility model
Fig. 2 is the structural representation of eyepiece of the present utility model
Among the figure, 1 helmet, 2 panels, 3 switches, 4 optical sensors, 5 eyepieces, 6 preceding protective sheet, 7 variable color sheets, 8 back protective sheet.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is made specific description.
This utility model is by being made up of the helmet 1, panel 2.The helmet can be fixed on the user head with whole device, and carrying battery case, control circuit and panel 2.On and off switch 3, eyepiece 5, optical sensor 4 are arranged on the panel 2, wherein eyepiece 5 is a three-decker, eyepiece 5 is made up of protective sheet 6, the variable color sheet 7 in intermediate layer and the back protective sheet 8 of internal layer before outer field, and preceding protective sheet 6 and back protective sheet 8 are clear glass, and variable color sheet 7 is a liquid crystal material.Preceding protective sheet 6 is subject to erosions such as welding slag, is consumable accessory, is designed to changeable type on the structure.
Claims (1)
1. electric welder's helmet with an automatic light meter, form by the helmet (1) and panel (2), it is characterized in that: be fixed with eyepiece (5), switch (3) and optical sensor (4) on the panel (2), described eyepiece (5) is made up of protective sheet (6), the variable color sheet (7) in intermediate layer and the back protective sheet (8) of internal layer before outer field, preceding protective sheet and back protective sheet are clear glass, and the variable color sheet is a liquid crystal material.
