Abstract

The utility model relates to a welding mask, in particular to a welding mask with openable eyepiece. The utility model has the technical proposal that a pull-thread type welding mask comprises a mask and a deep color eyepiece, the deep color eyepiece is arranged on the mask movably, and one end of the deep color eyepiece along the slideway direction is provided with an openable transmission mechanism. The structure is adopted, and the slide of the eyepiece is easily controlled by a pull thread when welding, which protects effectively the eyes and the skin of face; the operation efficiency is improved, and it is easy in use. The fixed colorless or light eyeglass can stop effectively the smog and the splashing welding slag, and so protect the eyes and the deep color eyepiece.

Description

But folding eyepiece welders' mask

Technical field

This utility model relates to a kind of welders' mask, but the welders' mask of folding eyepiece particularly.

Background technology

The employed face shield of past welding worker is that dark eyepiece is fixed on the face shield, and one hand is held face shield and operated, and has caused great inconvenience to the operator, influence operation and welding quality, the eyes of also very easily burning simultaneously.

For addressing this problem, but a kind of welders' mask of folding eyepiece has appearred.The utility model patent communique discloses a kind of patent No. and has been 94215447.9 and is called the utility model patent of " but welders' mask of folding eyepiece ", but is that dark eyepiece is made the folding eyepiece, by the opening angle of control eyepiece, reaches the purpose of folding.Because these two kinds of face shields must remove to put down the face shield or the eyepiece that closes with the hands of taking welding wire or weldment before welding, and then carry out welding operation, under dark eyepiece light blocking situation, welding gun is difficult for finding the weldering node, during especially for little weldment or stainless steel silk welding, must take weldment or welding wire with a hands, the another hands takes welding gun to operate the inconvenience that operates like this, inefficiency, and welding quality is undesirable, also very easily burn eyes and skin.

The utility model content

The purpose of this utility model is to provide a kind of high efficiency, but can improve the folding eyepiece welders' mask of welding quality.

To achieve these goals, this utility model adopts following technical scheme: but a kind of folding eyepiece welders' mask comprises face shield and dark eyepiece, dark eyepiece is slidedly assemblied on the face shield, and dark eyepiece is connected with the folding actuating device along an end of slideway direction.

Described actuating device comprises a backguy that is installed in the backguy sheath, and the two ends of backguy sheath are provided with fixed sleeving, and fixed sleeving one end is fixed on the face shield, and an other end is connected with the backguy retaining collar, and manually the backguy of control end is provided with the backguy acting ring.

Described backguy should be the two ends softer material of hard interlude and makes.

The described dark eyepiece outside also is equipped with colourless or the light color eyeglass.

After having adopted said structure, directly, eyepiece is used have more randomness and motility by the folding of backguy control eyepiece.A hands both can have been controlled the folding of eyepiece, and the while can take between weldering again or welding wire goes to weld, and has improved work efficiency and welding quality largely, and has effectively protected eyes and skin of face.Use fixing colourless eyeglass can stop smog and the welding slag that splashes, reach the purpose of protection eyes and eyepiece, reduced the cost that the dark eyepiece of frequent replacing is brought.

Description of drawings

But Fig. 1 is the structural representation of folding eyepiece welders' mask.

The specific embodiment

But folding eyepiece welders' mask as shown in Figure 1 comprises face shield 1 and dark eyepiece 3, and dark eyepiece 3 is slidedly assemblied in the chute frame 4 of face shield 1, and dark eyepiece 3 is connected with the folding actuating device along an end of slideway direction.Actuating device comprises a backguy 5 that is installed in the backguy sheath 6, the two ends of backguy sheath 6 are provided with fixed sleeving 9, fixed sleeving 9 one ends are fixed on the face shield 1, an other end is connected with backguy retaining collar 7, manually the backguy 5 of control end is provided with backguy acting ring 8, backguy 5 should be the two ends softer material of hard interlude and makes, such as steel wire.Dark eyepiece 3 outsides also are equipped with colourless or light color eyeglass 2, can stop smog and the welding slag that splashes, and reach the effect of protection eyes and dark eyepiece 3.

After the welder is with face shield 1, backguy Fixing shrink ring 7 is fixed on wrist or the palm, make backguy 5 leading-out terminals be in position, the centre of the palm, middle finger, the third finger are being inserted in the backguy acting ring 8, the thumb of this hands and forefinger are picked up welding gun in weldment or welding wire and the another hands to for after accurately then, the nameless contraction of middle finger drives backguy acting ring 8, and the thrust that makes progress by backguy acting ring 8 makes position when sliding to welded condition on the dark eyepiece 3 by backguy 5.Be case of bending when the middle finger third finger stretches gently or is returned to, dark eyepiece 3 just slides to state to be welded by under the pulling force of backguy 5.

Claims
