Abstract

The utility model relates to a safety welding helmet, comprising a welding helmet, a black lens and a welding handle. The utility model is characterized in that the outside of the window of the welding helmet is provided with a protective cover with transparent glass, the lower part of the window in the protective cover is provided with the black lens which can block the window by pushing upwards one end of a push rod at the lower side of the protective cover, and a holding clamp which is connected with the other end of the push rod through a lacing wire is arranged on the welding handle. The utility model has the advantages of reasonable structure, convenient welding operation, high work efficiency, high safety, etc., and large components as well as small components can be welded.

Description

Safety hood for welder

This utility model belongs to a kind of electric welding auxiliary device technical field.

Welding helmet is electric welding operator's an indispensable instrument.Present normally used welding helmet and electrode holder are without any the branch body structure of getting in touch, and so in use can bring inconvenience, because the welder is when welding, need one and hold weld cap, the another hands is taken electrode holder, uses very inconvenient like this, inefficiency, dangerous again.Though also have a kind of welding helmet need not grasp in use in addition, when observing the welding situation, also handy hands moves up and down black eyeglass.Therefore, when two smaller workpiece of welding, need other people to assist and to weld; Working environment than higher, again under the dangerous situation, a people also is difficult to finish.

The purpose of this utility model provides a kind of new type of safe welding helmet that welding helmet and electrode holder are combined as a whole.

The purpose of this utility model is achieved in that it includes weld cap, black eyeglass, electrode holder, it is characterized in that having the protective cover of a band clear glass in the window arranged outside of weld cap, in protective cover the bottom of window be provided with one can be by pushing away the black eyeglass that blocks window on its downside push rod one end, electrode holder is provided with one by lacing wire and the joining folder of holding of the push rod other end.Be provided with a return spring that links to each other with push rod on the top that above-mentioned push rod links to each other with lacing wire.This welding helmet in use, the hand-held electrode holder of the welder folder of holding with a firm grip, the end that lacing wire this moment drives push rod moves down, the other end pushes away the black eyeglass on then and blocks window, this moment is normally electric welding operation just, after the operation, unclamps and holds folder, push rod return under the effect of return spring then, black eyeglass be return thereupon also.

This utility model is owing to organically be connected as one welding helmet and electrode holder, therefore have rational in infrastructure, electric welding is easy to operate, high efficiency, big smallclothes all can be welded, advantage such as safe and reliable.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is this utility model perspective view.

Fig. 2 is the structure principle chart of Fig. 1.

Shown in Fig. 1-2,1 is weld cap, the protective cover 4 that one band clear glass 3 is arranged in weld cap window arranged outside, in protective cover the bottom of window be provided with one can be by pushing away the black eyeglass 8 that blocks window on its downside push rod 10 1 ends, the other end of push rod connects by the folder 7 of holding on a lacing wire 5 and the electrode holder 6, be provided with a return spring that links to each other with push rod 9 on the top that push rod links to each other with lacing wire, this push rod is to be fixed on the weld cap by the bolster 11 near the end that is connected with lacing wire to realize.Also be provided with an illuminating lamp 2 on the top of weld cap window.When the welder states structure in the use, need be with weld cap earlier, see through clear glass and determine solder joint, when working environment is relatively darker, can open illuminating lamp, the hand-held then electrode holder folder of holding with a firm grip, an end of lacing wire pulling this moment push rod moves down, and the other end pushes away the black eyeglass on then and blocks window, this moment is normally electric welding operation just, operation is finished, and unclamps and holds folder, then push rod return under the effect of return spring, the black eyeglass also moves down return thereupon, thereby has finished the use of welding helmet.

Claims

1, a kind of new type of safe welding helmet, it includes weld cap, black eyeglass, electrode holder, it is characterized in that having the protective cover of a band clear glass in the window arranged outside of weld cap, in protective cover the bottom of window be provided with one can be by pushing away the black eyeglass that blocks window on its downside push rod one end, electrode holder is provided with one by lacing wire and the joining folder of holding of the push rod other end.

2, safe welding helmet according to claim 1 is characterized in that being provided with on the top that push rod links to each other with lacing wire a return spring that links to each other with push rod.
