Abstract
The utility model relates to a protecting tool used in electric welding, in particular to an eye protecting tool used in the electric welding. The eye protecting tool used in the electric welding comprises a mask body, glass optical lenses and a breath air hole, wherein the glass optical lenses comprise a fixed colorless glass optical lens and a colored glass lens, the colored glass lens is arranged in front of or behind the colorless glass optical lens and is capable of sliding vertically, and small sliding grooves are formed in two sides of the colorless glass optical lens. The colored glass lens is connected with an elastic returning frame, wherein the elastic returning frame is connected with the mask body above the colored glass lens through screws, and tensile force of the elastic returning frame is upward. A pair of chin rests is arranged on chin positions of the mask body, wherein a draw bar is connected between the chin rests, the middle of the draw bar is fixed on the mask body by a returning spring, and the tensile force of the returning spring enables the chin rests to be tucked towards the chin positions. A tension rope is connected with each of two tail ends of the draw bar, and the other end of each tension rope is connected with the elastic returning frame through a pulley. The direction of the tensile force of each tension rope is opposite to the connection direction with the elastic returning frame. According to the eye protecting tool used in the electric welding, conversion between sun blocking and flight lighting is achieved only by motions of the chin positions, and therefore both hands of a welder are enabled to be completely free, and further the danger of falling down in aloft work is avoided.
Description
Technical field
This utility model relates to a kind of electric welding protector, particularly a kind of electric welding Eye protection device.
Background technology
When doing electric welding, tend to occur mismate between left hand and the right hand, perhaps left hand buttresses thing when high-altitude application, the high light that electric welding is sent is easy to stab eyes or facial the burn, bring great injury to the people, also do not have a kind of electric welding Eye protection device fully to free welder's both hands at present.
Summary of the invention
I provide a kind of and only transform by movable just can the finishing between eyes lucifuge and the zero diopter of cheek, thereby welder's both hands are fully freed.
This utility model is achieved in that the electric welding Eye protection device, formed by mask main body 1, glass lens, respiratory ventilation hole 8, described glass lens is by a fixing flint glass eyeglass 5, in its place ahead or the rear coloured glass eyeglass 3 that can slide up and down is set, there is slip sulculus 11 both sides, coloured glass eyeglass 3 upper ends are connected with elastic reset frame 12, elastic reset frame 12 is connected in by screw 13 on the mask main body 1 of coloured glass eyeglass 3 tops, and the tension force of elastic reset frame 12 upwards; Be positioned at mask main body 1 cheek position a pair of chin rest 7 is arranged, be connected with pull bar 10 on the chin rest 7, pull bar 10 middle parts are fixed on the mask main body 1 by return spring 9, because return spring 9 tension force make the chin rest 7 draw in to the cheek direction, the end of pull bar 10 is connected with respectively line of pull 4, line of pull 4 is connected in the other end on 12 of the elastic resets by pulley 2, and line of pull 4 is opposite with the line direction tension direction of elastic reset frame 12 links;
Further:Described elastic reset frame 12 is the W type, and two end minimum points connect coloured glass lens 3, and the summit, middle part is connected on the mask main body 1, and line of pull 4 is connected to two end minimum points to the position between the summit, middle part, closure to lower and on;
Further:There is compensating roller button 6 the described chin rest 7 rear ends, the pressure size of 7 pairs of cheeks of the scalable chin rest.
Useful technique effect of the present utility model: transform by movable just can the finishing between eyes lucifuge and the zero diopter of cheek, thereby welder's both hands are fully freed, thus the danger of having thrown from eminence when having avoided work high above the ground.
Description of drawings
Fig. 1: structural representation of the present utility model.
Among the figure: 1-mask main body, 2-pulley, 3-coloured glass eyeglass, 4-line of pull, 5-flint glass eyeglass, the compensating roller button of 6-, the 7-chin rest, 8-respiratory ventilation hole, 9-return spring, 10-pull bar, 11-slip sulculus, 12-elastic reset frame, 13-screw.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is described further, understands to make things convenient for the technical staff:
1, electric welding Eye protection device, such as Fig. 1, formed by mask main body 1, glass lens, respiratory ventilation hole 8, described glass lens is by a fixing flint glass eyeglass 5, in its place ahead or the rear coloured glass eyeglass 3 that can slide up and down is set, there is slip sulculus 11 both sides, coloured glass eyeglass 3 upper ends are connected with elastic reset frame 12, elastic reset frame 12 is connected in by screw 13 on the mask main body 1 of coloured glass eyeglass 3 tops, and the tension force of elastic reset frame 12 upwards; Be positioned at mask main body 1 cheek position a pair of chin rest 7 is arranged, be connected with pull bar 10 on the chin rest 7, pull bar 10 middle parts are fixed on the mask main body 1 by return spring 9, because return spring 9 tension force make the chin rest 7 draw in to the cheek direction, the end of pull bar 10 is connected with respectively line of pull 4, and line of pull 4 is connected in the other end on 12 of the elastic resets by pulley 2.
, embodiment 1Described line of pull 4 is opposite with the line direction tension direction of elastic reset frame 12 links.
, embodiment 1Described elastic reset frame 12 is the W type, and two end minimum points connect coloured glass lens 3, and the summit, middle part is connected on the mask main body 1, and line of pull 4 is connected to two end minimum points to the position between the summit, middle part, closure to lower and on.
, embodiment 1There is compensating roller button 6 the described chin rest 7 rear ends, the pressure size of 7 pairs of cheeks of the scalable chin rest.
Operation principle: mask main body 1 is worn over face, the chin rest 7 is stuck in cheek, eyes are outside by flint glass eyeglass 5 observables, coloured glass eyeglass 3 generally places the top of flint glass eyeglass 5, the chin rest 7 is generally owing to drawing in to cheek about return spring 9, when two cheeks of clenching one's teeth are heaved, the chin rest 7 promotes line of pull 4 and acts on elastic reset frame 12 by pulley 2, thereby make coloured glass eyeglass 3 cover flint glass eyeglass 5 along sulculus 11 down slidings, thereby real lucifuge.
