Abstract
The utility model relates to a light-controlled face mask for electric welding. The utility model is characterized in that the utility model is composed of a photorelay and a face mask connected with a safety cap. A pair of transparent glasses are arranged on the face mask, and a pair of eye protecting sunglasses forming an angle of 20 DEG to 30 DEG with the transparent glasses are arranged in the face mask. The photorelay comprises a photoelectric tube arranged on the front edge of the safety cap, a magnetic switch connected with the eye protecting sunglasses, an amplifier and a power supply part, wherein, the magnetic switch controls the closing of the eye protecting sunglasses and the transparent glasses. The utility model has the characteristic of convenient use, and can prevent a human body from being injured by ultraviolet rays to the utmost extent.
Description
The utility model relates to a kind of electric welder's helmet, particularly a kind of light-operated electric welder's helmet.
Existing electric welder's helmet need with hand lift retaining in the face front with the protection eyes, exist to use not too convenient and might have little time to hide the defective that sight line is damaged eyes because of the welding rod starting the arc.
The purpose of this utility model is to provide a kind of need not to hand, and the electric welder's helmet that goggles can auto-closing in the electric welding starting the arc.
The purpose of this utility model is achieved in that by face shield that is connected with safety cap and photorelay to be formed, face shield is provided with bright mirror, be provided with in the face shield with bright mirror is separated into 20 ° of-30 ° of angles and protect the order sunglasses, photorelay comprise the photoelectric tube that is arranged on the safety cap leading edge, with protect magnetic switch (electromagnetic relay), amplifier and the power unit that the order sunglasses link to each other and control itself and bright mirror closure.When the electric welding starting the arc, the photoelectric tube of cap leading edge absorbs arclight and produces photoelectric effect, and circuit is connected, and by amplifier performance effect, makes magnetic switch produce magnetic, drives eye guard sunglasses and bright mirror closure, reaches the purpose of protection eyes.Photoelectric tube only tells on to arc light and stronger light, can not tell under general light and the oxy-arc light.Electric welding during the starting the arc, is not protected order sunglasses and bright mirror and is separated into 20 ° of-30 ° of angles, then can guarantee the bright of sight line, makes it not take off face shield and still can see workpiece clearly.
For the protection head, prevent bump, adjustable cap bracket is housed in safety cap.On one's body preventing that spark from splashing, be connected with the flameproof fabric cover in the lower end of face shield.
For ease of under the darker situation of light, seeing workpiece clearly, also be provided with illuminating lamp in the cap leading edge.
The utility model is owing to combine safety cap and face shield, thereby saved the trouble of hand shield; Owing to adopt light-operated closed goggles, thereby can avoid the starting the arc to have little time to block sight line and the situation of damaging eyes takes place.In addition, the utility model also has safer, the convenient characteristics of using.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model front schematic view;
Accompanying drawing 3 is the utility model photorelay schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, be connected with safety cap 1 in the face shield upper end, adjustable cap bracket 8 is housed in the cap, the cap leading edge is installed with illuminating lamp 12 and photoelectric tube 13 side by side, amplifier circuit board 6 and battery 7 are arranged between safety cap and the cap bracket, the face shield front is provided with bright mirror 2, be provided with in the face shield and protect order sunglasses 10 and nose-bridge frame 9, goggles becomes 20 ° of-30 ° of angles with bright mirror under the support of nose-bridge frame, join by lead magnetic switch 3 that links to each other with circuit board 6 and the trace that protects the order sunglasses, the closure of control goggles is protected a torque spring 4 is set on the order sunglasses trace, keep often opening so that protect the order sunglasses, the face shield lower end connects flameproof fabric cover 5.
As shown in Figure 3, photorelay is made up of power supply, photoelectric tube, amplifier, electromagnetic relay.When arc light irradiates light fulgurite, produce electric current in the phototube circuit, after amplifier amplifies, make electromagnet M magnetization, N holds armature, when not having arc light irradiates light fulgurite, there is not electric current in the circuit, armature leaves M under the effect of spring, with armature N with protect order sunglasses trace and link to each other, promptly reach the purpose of control automatically.
Claims (3)
1, a kind of light-operated electric welder's helmet, it is characterized in that forming by face shield that is connected with safety cap and photorelay, face shield is provided with bright mirror, be provided with in the face shield with bright mirror is separated into 20～30 ° of angles and protect the order sunglasses, photorelay comprise the photoelectric tube that is arranged on the cap leading edge, with protect magnetic switch, amplifier and the power unit that the order sunglasses link to each other and control itself and bright mirror closure.
2, light-operated electric welder's helmet according to claim 1 is characterized in that being equipped with in the safety cap adjustable cap bracket, and the face shield lower end is connected with the flameproof fabric cover.
