CN2314765Y - Automatic face mask for welding worker - Google Patents

Abstract

The utility model relates to an automatic mask for welding workers, which can be matched with various alternating current welding machines and direct current welding machines; a battery and a circuit board are arranged in a cavity of the upper part of the mask; the circuit board is controlled by a phototransistor which is outward arranged; a double-D trigger on the circuit board is logically controlled; a PNP tube is used for driving a miniature motor; a belt of the miniature motor is used for pushing sunglasses to move up and down for opening and closing operation; a sponge strip has a damping function for the sunglasses; a permanent magnet has a falling-proof function for the sunglasses and is used for fixing the sunglasses to have a safety protection function for arc light in an initial period. The problem that the mask is held is solved and the harm of arc light and welding slag to welding workers, when arc is started on welding workers is avoided; the stimulation for the auditory nerve of welding workers stimulated by a switching mechanism of the sunglasses ensures the health of the welding workers; welding speed and welding quality are improved.

Description

The automatic mask of electric welder

This utility model relates to the automatic mask that a kind of electric welder uses, particularly a kind of can with the supporting automatic mask of various AC-DC welders.

The shortcoming that the useful hands of traditional solder mask grips, have in the burn shortcoming of welder's eyes and skin of face of starting the arc moment, the patent No. 94243736.5, name is called the utility model patent of the automatic mask of a kind of welder, though overcome hand-held shortcoming, but its electric magnet buzzer, it is unhappy that the dull click of moving ferrum is sneered sound, still have the wonderful arc light of 0.1-0.2 of starting the arc moment to see through burn welder's the shortcoming of eyes (than hand-held good having manyed of mask) of colourless blank lens, to welder's eyes, the protective action deficiency of auditory nerve.

The purpose of this utility model provides a kind of automatic mask, can make the welder see workpiece clearly again at a forearc, can avoid the stimulation of arc light in starting the arc moment again to eyes, fly the burning that be cut to skin, can get rid of the patent No. again and be the hard to bear electric magnet buzzer of the sort of welder of order of 94243736.5 masks and the click of moving ferrum and sneer sound, can improve welding quality, guarantee welder's eyes, skin, physical and mental health again.

This utility model is to realize like this; wiring board of device in the mask top empty boxes of compression molding; one Battery pack; wiring board connects photosensitive three plate pipes outward; photosensitive triode plays effect of light sensing and control circuit board work; double D trigger on the wiring board is as logic control; drive as two-way micromachine with the PNP pipe; two-way micromachine promotes the action of sunglasses switching mechanism; be provided with the groove frame around the sunglasses range of movement; the groove frame plays the guide rail effect; be equipped with the sponge bar up and down in the groove; the sponge bar plays the buffering damping action to black lens; the middle window of mask fixedly mounts two-layer eyeglass; skin is colourless eyeglass; internal layer is a Sunglasses lenses sun clips, and outer for flying the protective layer that is cut, internal layer can make the welder see workpiece clearly at a forearc; can play the initial stage protective effect to eyes in starting the arc moment again; finally making mask is automatic mask, makes the welder can see workpiece clearly, has got rid of hand-held inconvenience again; both avoided the injury of arc light to eyes; fly to be cut to the burning of skin and eyes, got rid of the buzzer of magnet coil iron core again, the click of moving ferrum is sneered the stimulation of sound to welder's auditory nerve; both improve welding quality, and can guarantee welder's health again.
