Abstract
The utility model relates to an arc preventing mask for an electric welding machine, which is composed of a mask, an arc-surface preventing lens, an electric magnet, a connecting component, a relay, etc. The relay is opened or closed by the control of the output voltage of the electric welding machine. Meanwhile, the normal close point of the relay is connected with an electric source and an electric magnet. The purpose of automatically lifting up or closing the arc-surface preventing lens is obtained by adopting the magnetic force of the electric magnet to suck and pull the connecting component. The mask has simple structure and convenient use, particularly the two hands can simultaneously work in the weld. The weld efficiency is increased. The utility model is suitable for the use of using the electric welding machine for welding in various occasions.
Description
This utility model relates to the anti-cambered surface cover of a kind of protective mast, particularly electric welding machine.
In common electric welding, the arc light that sends during for fear of electric welding adopts a kind of easy hand-held anti-cambered surface cover to the harm of eyes, this face shield is handed owing to must use in use, have only a hands to be used for welding job, reduced welding efficiency, and in use very inconvenient; Eyes also have the preventing arc eyeglass on a kind of face shield, after electric welding finishes, can eyeglass be propped up, so that can more clearly be observed the welding situation with hands, owing to eyeglass must be depressed in use, when stopping welding job, must eyeglass be propped up with hands again, therefore use also very inconvenient.
The anti-cambered surface cover that provides a kind of anti-globoidal mirror to play a protective role automatically with the open and close of electric welding machine is provided the purpose of this utility model, can improve the efficient of welding job again simultaneously, and eyes are played the better protect effect.
Realize that basic scheme of the present utility model is:
One relay is set in the middle of power supply and electric magnet, design a connection piece is connected with anti-globoidal mirror in the electric magnet bottom, the adhesive that output voltage when utilizing the welding of electric welder no-load or electric welding machine comes control relay is when electric welder no-load, because output voltage is higher, the normally closed point of relay disconnects, no magnetic force produces on the electric magnet at this moment, and the connector that is connected with anti-globoidal mirror is not subjected to magnetic attraction, and connector will be by a spring pull-up, like this, anti-globoidal mirror is opened; When electric welding machine welds, because output voltage is lower, the normally closed closure of relay, electric magnet is inhaled and is drawn connector to make anti-globoidal mirror closure owing to the power supply effect produces magnetic force, lifts automatically and closed purpose of preventing globoidal mirror thereby reached.
Because in welding; output voltage control electric magnet when adopting electric welder no-load and welding produces magnetic force; and come the adhesive connector to control by electric magnet and prevent lifting and closure of globoidal mirror; reached the purpose of automatic protection eyes; simultaneously, because anti-cambered surface cover is worn over head, takes off face shield or lift anti-globoidal mirror without hands during welding; make and in welding, can work simultaneously by two handss, improved the efficient of welding.
The utility model will be further described below in conjunction with embodiment.
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is a cross-sectional view of the present utility model
Referring to Fig. 1,1. relay, 2. electric magnet; 3. connector, 4. spring, 5. anti-globoidal mirror is 6. watched mouth.A, B connect the electric welding machine output voltage, and C, D connect 220 volts of power supplys, and when electric welder no-load, because output voltage is higher, as 80 volts, scalable rheostat R moves relay in the time of 80 volts, at this moment, and normally closed some Z of relay
1, Z
2Disconnect, anti-globoidal mirror is opened automatically by connector control under the effect of spring, and when electric welding machine welded, because output voltage is lower, as 20 volts, at this moment, relay was failure to actuate, normally closed some Z of relay
1, Z
2Closure, electric magnet produce magnetic force under the effect of power supply, magnetic force is inhaled and drawn connector and then will prevent the globoidal mirror closure.
Referring to Fig. 2, anti-globoidal mirror 5 is movably placed on the holder 9 of face shield 7 both sides by a cross bar 8, on the holder of a side, flexibly connect connector, connector is flexibly connected by wishbone and U-shaped frame and forms, the top movable of wishbone places on a side and the cross bar that anti-globoidal mirror links to each other, can drive the motion of anti-globoidal mirror according to its motion, its top links to each other with spring 4, spring 4 one ends are fixed in the top of face shield 7, the other end links to each other with connector, it can be when relay 1 disconnects, to prevent globoidal mirror 5 pull-ups, one side of the bottom of wishbone and U-shaped frame flexibly connects, and the bottom of U-shaped frame is movably placed on the fixed axis of face shield sidepiece by fixed axis 10, the another side top of U-shaped frame links to each other with electric magnet 2, and adhesive control circuit that relay 1 and rheostat R form and electric magnet are connected.When electric welder no-load, the normally closed point of relay disconnects, and anti-globoidal mirror is by spring 4 pull-ups; During electric welding machine work, relay 1 is connected, and electric magnet produces the magnetic attraction connector will prevent the globoidal mirror closure; Be connected to a rheostat R between relay 1 and electric welding machine output voltage, thereby the variation of output voltage guarantees the action of relay when adjusting because of electric welder no-load.
Claims (3)
1. an electric welding machine is prevented cambered surface cover, comprise face shield 7 and anti-globoidal mirror 5, it is characterized in that it also has electric magnet 2, connector 3, relay 1, relay is disconnected or closure by the output voltage control of electric welding machine, the normally closed point of relay connects power supply simultaneously, electric magnet 2 can be inhaled and draw the anti-globoidal mirror 5 of connector 3 drives to mention or closure, and anti-globoidal mirror 5 is movably placed in by a cross bar 8 on the holder 9 of face shield 7 both sides, and connector is flexibly connected by wishbone and U shaping frame and forms, the top movable of wishbone places on a side and the tringle 8 that anti-globoidal mirror is connected, connector 3, electric magnet 2, relay 1 fixedly place the side inside of face shield 7.
2. anti-cambered surface cover according to claim 1 is characterized in that being connected between described relay 1 and electric welding machine output voltage a rheostat R.
3. according to claim 1 and the described anti-cambered surface cover of claim 2, it is characterized in that its also tool one spring 4, spring 4 one ends are fixed in face shield 7 tops, and the other end links to each other with connector 2, and it can will prevent globoidal mirror 5 pull-ups when relay 1 disconnects.
