Abstract
The utility model relates to a head-wearing electric welding mask, which can lift electric welding glass automatically and is an auxiliary tool for electric welding. A piece of electric welding glass (5) provided with a rotating shaft (7) is additionally arranged on the original electric welding mask. Under the function of a pulling cable (6) connected with the hand brake (9) of a pair of electrode holders, the electric welding glass (5) is closed by clamping the hand brake (9) during electric welding, and the electric welding glass (5) can be stretched automatically by loosening the hand brake (9). The utility model has the advantages of simple structure, convenient use and low price.
Description
Can protect eyes not to be subjected to the radiation of arc light when this utility model relates to a kind of the welding, can make things convenient for the instrument of clearly seeing face of weld situation clearly again when going out weldering.
At present, electric welder's helmet can divide two classes substantially, and a class is portable face shield, and a class is the wear-type face shield.The structure of the electric welding glass part of these face shields all is fixed, see face of weld situation clearly and all must take face shield away.Newer version is to lump together by triplex glass is overlapping, and ground floor is for absorbing or the uv reflectance special glass, and the second layer is for absorbing or the reflected infrared ray special glass, and the 3rd layer is the filter glass of appropriateness.First and second layer is put into viewing mask during use; the 3rd layer of filter glass is contained in another frame; rely on rotating shaft to open, when welding, the 3rd layer overlaps with one, two layer; play a protective role; when the postwelding that goes out need be observed workpiece, the filter glass of outwarding winding can clearly be seen the face of weld, has tentatively solved and should protect eyes; see the contradiction of workpiece again clearly, but some trouble is gone up in operation.Up-to-date also have a kind of be can be with an automatic light meter welder's protective glass, during no electric arc, abundant printing opacity, when electric arc was arranged, the fine shading of energy did not need protective glasses is taken up and down, but the cost costliness.
Task of the present utility model provides a kind of headgear type electric welding mask, can protect eyes when it can realize welding easily, and the postwelding that goes out can clearly be seen face of weld situation clearly, and is simultaneously cheap.
For solving above-mentioned task; the solution that the present invention adopts is: on original headgear type electric welding mask basis; original electric welding glass is changed into the zero diopter white glass; inlaying on the frame of white glass; the electric welding glass that can stir (5) of rotating shaft (7) is installed; in the electric welding glass rotating shaft (7) that can stir opening type spring (4) is housed; go up around a few circle drag-lines (6) in rotating shaft (7); drag-line (6) connects together with the rim brake (9) that is contained on the soldering turret (8); during welding; by clutching rim brake (9) electric welding glass (5) is closed, play the effect of protection eyes, postwelding goes out; unclamp rim brake (9); under spring (4) tension force effect, electric welding glass (5) is opened automatically, eyes just can be clear that the situation of the face of weld.
Owing to adopted drag-line in the above-mentioned solution and opened spring, make electric welding glass opening and closing easily, like this when welding, particularly in work high above the ground and when overhead welding, just can a hand steered dependence thing, make health obtain balance, obtain the security psychologically, reduced danger.Simultaneously, also can just can remove to hold up accurate joint on the other hand when the butt joint welding, welding is more convenient so more accurate on the other hand.Simultaneously easy to use, price is half of former face shield only.
Be described in further detail below in conjunction with accompanying drawing: accompanying drawing is structural plan figure.
In general assembly drawing shown in the drawings, the helmet (1) links together by riveted joint with the glass picture frame (2) of zero diopter, the electric welding glass shaft seating (3) that can stir links together by screw and picture frame (2), electric welding glass (5) just can stir in bearing (3) by rotating shaft (7), opening type spring (4) is installed in the rotating shaft (7), one end is supported on the picture frame, the other end is supported on the following one side of electric welding glass (5), drag-line (6) is gone up around several circles in electric welding glass rotating shaft (7), drag-line (6) links to each other with rim brake (9) on being fixed on electrode holders (8), clutch rim brake (9) and strained drag-line (6), drag-line (6) in electric welding glass rotating shaft (7) is drawing electric welding glass (5) rotation, thereby closed electric welding glass (5), unclamp rim brake (9), under opening type spring (4) effect, electric welding glass (5) is opened automatically.
Claims (3)
1, a kind of headgear type electric welding mask, by the helmet (1), the drag-line (6) of electric welding glass that can stir (5) and control electric welding glass (5) is formed, it is characterized in that: clutch rim brake (9) during welding, electric welding glass (5) is closed the protection eyes effect of playing, unclamp rim brake (9) when going out weldering and open electric welding glass (5) automatically, can clearly see face of weld situation clearly; The switching of electric welding glass (5) is opened spring (4) by one and the drag-line (6) that is wrapped in the rotating shaft is controlled, and drag-line (6) is connected with rim brake (9) on the soldering turret again, puts the switching of controlling electric welding glass (5) by pinching of rim brake (9).
2, electric welder's helmet according to claim 1, its characteristics are: this stirs device is that an electric welding glass (5) is fixed on the face shield by rotating shaft (7), makes it be in normally open by an opening type spring (4).
3, electric welder's helmet according to claim 1 is characterized in that: this stirs that device closes is to control by a drag-line (6) that is wrapped in the rotating shaft, and drag-line (6) is controlled with the rim brake (9) on the soldering turret (8).
