Abstract

The utility model discloses a window controllable arc welding face mask, relating to an open arc welding mask, belonging to a workmen's labor protection tool. The aim is that an electric welder can vacate a hand to maintain the balance of human body, and therefore, the operating difficulty is reduced. The window controllable arc welding face mask comprises a casing window structure, goggles, a lever system, and a control mechanism which can be detachably arranged on the handle of welding tongs. The operating difficulty of the electric welder can be reduced by the utility model, in particular, in the condition of uphill working, the safety and the flexibility of the operation is increased. The utility model has the advantages of eliminating blind striking arc, reducing the damage of workpieces, improving the welding quality, saving electric power and the labor force.

Description

Window controllable arc welding helmet

This utility model relates to a kind of open-type electric welding mask, specifically is the controlled window electric welder's helmet of a kind of wear-type, and it is the labor protection apparatus of welding worker.

At present both at home and abroad the employed electric welder's helmet of welding worker can divide two kinds of hand held and wear-types, these two kinds of face shields generally all have fixed protective eye lens structure, but wherein the protective eye lens controlled architecture has also appearred in the hand held electric welder's helmet, and it is to make the protective eye lens structure of closure or openness neatly by the switch in the pressing handle.When electric welding field, use headgear type electric welding mask or the uncontrollable hand held electric welder's helmet of protective eye lens to make troubles to the operator, they must take down electric welder's helmet and put on frequently in order to see welding work pieces and welding region clearly, and are extremely inconvenient; Use the controlled hand held electric welder's helmet of protective eye lens just needn't take down every now and then and put on electric welder's helmet and see the outside situation clearly, more convenient, but also need to hold electric welder's helmet and control protective eye lens specially with a hands, this is still inconvenient when ascend operation, and welding worker takes electric welder's helmet to take soldering turret on the other hand on the other hand, and operation easier is very high, especially when certain workpiece of welding, the operator does not have enough spaces and stands firm, and operation easier is just higher, and accidents happened easily.In addition, when the extraordinary workpiece of welding, need to hold workpiece with hands, often must be cooperated by two people during operation, difficulty is also higher.

The purpose of this utility model is to provide a kind of wear-type controlled window electric welder's helmet, keeps balance own so that welding worker can be vacateed a hands when ascend operation, thereby reduces operation easier; Can be when the extraordinary workpiece of welding (needing to hold the welding of workpiece) by one man operation with hands.

This utility model is to realize like this.It is the controlled window electric welder's helmet of a kind of wear-type, has window structure, that a case, is arranged on the case outside and is arranged on protective eye lens in the window structure, and is arranged on controlling organization on the welding clamp handle removably by what a lever system made that described protective eye lens moves.

This utility model makes welding worker can vacate a hands when ascend operation and keeps balance own, thereby reduces operation easier; Can be when the extraordinary workpiece of welding (needing to hold the welding of workpiece) by one man operation with hands.During striking, the controlled mechanism controls of protective eye lens and be in certain position, and controlling organization is by the hand-guided of taking soldering turret, this has just increased the safety and the motility of operation.In addition, welding worker is when operation, and welding work pieces and welding region all in its sight line control, have been eliminated blindly striking, have reduced the workpiece damage, have improved welding quality, have also saved electric power and labour force.

Exemplify an illustrated embodiments of the present utility model below.

The controlled window electric welder's helmet of wear-type, referring to accompanying

drawing

1,3,4, it has a case 1, a slightly rectangular window 2 of evagination is arranged in the outside of case 1, the opening 3 that a strip is arranged on the window 2 outside one sides, there is one behind the opening 3 with hook 4 fixed flint glasss 5, two guide rods 8 are arranged behind the flint glass 5, they are fixed on the window 2, mirror holder 9 is enclosed within on the guide rod 8 by the collar 10, and it is gone up and links to each other with steel wire 12, links to each other with extension spring 11 down, can upper and lowerly move, wherein have one with hook 7 fixed protective eye lens 6; The motion of mirror holder 9 is controlled by a lever system by a controlling organization, with steel wire 13 is perpendicular a pull bar 14 arranged, it is fixed on the case 1 by fulcrum 15, the one end links to each other by a universal tieing 12 with steel wire 13, its other end links to each other by another universal tieing 16 with another steel wire 17, pull bar 14 is also vertical with steel wire 16, steel wire 17 stretches in the wired hose 19 by a support 18 that is fixed on the case 1, place separated by a distance also has a tight chieftain 20 that holds under the arm who is fixed on the case 1 below support 18, in order to wired hose 19 is located, referring to accompanying drawing 2, wired hose 19 is fixing by fixed mount 21, fixed mount 21 links to each other with spanner frame 22 and is positioned on the spanner frame 22, spanner frame 22 is connected with spanner 23 and return spring sheet 24, and also be connected with a lasso 26 on wrench frame 22 limits, spanner frame 22 can be fixed on the welding clamp handle 25 by it.Referring to accompanying

drawing

5,6,7, pull spanner 23 simultaneously in striking, driven steel wire 17, referring to accompanying

drawing

1,3,4, steel wire 17 tensions make universal tieing 16 be subjected to a downward pulling force and move downward, then this end of pull bar 14 also be subjected to a downward pulling force move down and cause the other end on move, universal tieing 12 is subjected to a pulling force that makes progress and moves upward and drive steel wire 13, the mirror holder 9 that the result will be put protective eye lens 6 is pulled on to the certain position place.
