Abstract
The utility model relates to a new protective face mask for welding, comprising an electric welding face mask. The utility model is characterized in that the observing hole of the electric welding face mask is provided with a spectacle lens box, and the lower part of the spectacle lens box is provided with an opening corresponding to the observing hole of the electric welding face mask; a transparent slice is arranged on the spectacle lens box wall corresponding to the opening, and the upper part of the spectacle lens box is provided with a filtering spectacle lens which is connected with a lifting device in the spectacle lens box; the lifting device is composed of a motor, a pulley wheel and a belt, wherein the motor is arranged on the top end of the spectacle lens box, the pulley wheel is arranged on the middle part of the box body, and the lock catch on the belt is connected with the filtering spectacle lens. A blower fan is arranged in the spectacle lens box, and the upper part of the spectacle lens box is provided with a vent hole. The utility model has the advantages of realizing the automatic hoisting of the color filter as required when the welding workers operate the welding to satisfy the observing requirement for welding preparation and the occlusion arc light when welding to protect the eyes from injury.
Description
Technical field
This utility model relates to a kind of welding face guard, particularly a kind of novel welding face guard.
Background technology
The electric welding operator generally protects with wearing overhead electric welding protective mask in electric welding at present; be to prevent that welding slag from splashing in the people on the face on the one hand; be to block with the protection eyes on the other hand with the arclight of the color filter film on the face shield to electric welding; because the workman needs earlier electrode wire and welding rod to be aimed at the welding position when operation; but because the color of color filter film is darker; when putting down; may block the observation of eyes; if and proficiency is taken welding gun behind aligning; another hands is taken welding wire; can't free hand to put down colour filter again, welding worker is brought difficulty.
Summary of the invention
The purpose of this utility model is to solve electric welder's helmet existing problem when electric welding is operated in the prior art, and a kind of novel electric welding protective mask of the colour filter of automatic lifting on demand is provided.This utility model designs a kind of novel welding face guard, comprise electric welder's helmet, it is characterized in that: an eyeglass box is arranged on the observation port of electric welder's helmet, the bottom of eyeglass box has and the corresponding opening of electric welder's helmet observation port, on the eyeglass box wall with respect to opening slide is arranged, on the top of eyeglass box one color filter film is arranged, color filter film is connected by the lowering or hoisting gear in the eyeglass box.Lowering or hoisting gear is made of motor and pulley, belt, and motor is installed in the top of eyeglass box, and pulley is at the middle part of box body, and the snap close on the belt connects color filter film.One blower fan is arranged in the eyeglass box, and the top of eyeglass box has the wind hole.The utility model has the advantages that and when welding worker is operated, to realize automatic lifting colour filter on demand, block arclight when satisfying observation requirement when welding is prepared and electric welding, preserve from the protection eyes.
Description of drawings
Below in conjunction with drawings and Examples this utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise electric welder's helmet 1 among the figure, it is characterized in that: an eyeglass box 3 is arranged on the observation port 2 of electric welder's helmet 1, the bottom of eyeglass box 3 has and electric welder's helmet 1 observation port 2 corresponding openings 4, on eyeglass box 3 walls with respect to opening 4 slide 5 is arranged, one color filter film 6 is arranged on the top of eyeglass box 3, and color filter film 6 is connected by the lowering or hoisting gear in the eyeglass box 37.Lowering or hoisting gear 7 is made of motor 8 and pulley 9, belt 10, and motor 8 is installed in the top of eyeglass box 3, and pulley 9 is at the middle part of eyeglass box 3, and the snap close 11 on the belt 10 connects color filter films 6.One blower fan 12 is arranged in the eyeglass box 3, and the top of eyeglass box 3 has wind hole 12.During use, can the positive and negative on and off switch and the electric welding machine of the motor 8 of lowering or hoisting gear 7 is synchronous, when when observing, lowering or hoisting gear 7 in the eyeglass box 3 is promoted to color filter film 6 at the top of eyeglass box 3, the operator can see through 5 pairs of pads of slide easily and observe and place easily welding wire and decide pad, during welding, start the welding machine switch, the motor 8 of lowering or hoisting gear 7 simultaneously electric decline, with color filter film 6 from putting down, can allow the electric welding operator carry out the control of welding quality by 6 pairs of pads of color filter film this moment, after stopping welding, the motor 8 of lowering or hoisting gear 7 gets electric rising, and color filter film 6 is promoted once more, so can guarantee the needs of using when welding worker is operated, not need the reuse hands to pull color filter film.And additional blower fan 12 and wind hole 13 be by taking out the turbid air in the face shield 1, improves workman's sultry during electric welding and ozone added in the face shield 1 in narrow space.
