Abstract
The utility model relates to a head-wearing electric welding mask. The color-changing part in the middle of the mask is ink glass using a liquid crystal display sheet to replace the traditional welding mask, and the color change of the liquid crystal display sheet is controlled by a control circuit which consists of a solar cell, an alkaline dry cell, a photoresistor and an oscillating circuit board. It has the advantages of less energy consumption, synchronous color change between welding arc light and LCD, capacity of protecting head, high welding efficiency, low cost, wide application range, etc.
Description
This utility model relates to a kind of solder set, concrete relates to a kind of headgear type electric welding mask.
Existing welding mask is covered with two kinds, and a kind of is the traditional electrical welding mask of hand-held, need use hand steered timing when welded piece, uses this face shield extremely inconvenient, because of consequently damaging electric welder's eyes with hand steered positive welded piece without face shield; Another kind is the novel electric welder's helmet of wear-type; it replaces sunglasses on the hand-held electric welder's helmet with LCD plate; LCD plate one end is connected on the electrode of electric welding machine; one end is connected on the electric torch; when welding gun contact welded piece; exchange electrically-driven liquid crystal on the circuit and show that sheet becomes dark color, thus protection electric welder's eyes.Though this face shield is than the convenience of hand-held, but also there is defective: when one, welding gun contacts welded piece, alternating current makes LCD plate become dark color in the circuit, but be not that each contact all can play arc light, becoming dark LCD plate makes electric welder's eyes not see welded piece, inconvenience welding gun contact for the second time welded piece, work efficiency is just low, generally speaking is that the welding job that rises behind the arc light of LCD plate work and electric torch is asynchronous; Two, draw a power line from electric welding machine and be attached on electric welder's the helmet of face welding mask, face shield use and preserve all inconvenient, also easily electric leakage during work.
The purpose of this utility model is to provide a kind of defective that can overcome above-mentioned existing electric welder's helmet; have again and use and preserve convenience; protection electric welder eyes are arranged; using basic battery and solaode are made power supply; welding job is synchronous after making the LCD plate work and the electric torch starting the arc; be difficult for electric leakage, can improve the liquid crystal display electric welder's helmet of advantages such as electric welding efficient greatly.
The purpose of this utility model can be achieved through the following technical solutions.
A kind ofly the helmet (1) of battery case (2) is installed and the panel middle part is equipped with liquid crystal display LCD sheet (6), solar energy sheet E by front upper part

2(8) connect with parallel way.
The helmet (1) is connected with hinge with face shield (5), and the maximum flip angle of face shield (5) is 90 °.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is for translating into 0 ° of structural representation behind the angle on the face shield on this utility model.
Now by following examples this utility model is done further detailed elaboration in conjunction with the accompanying drawings.
With reference to accompanying drawing: battery case (2) is contained in the preceding top of the helmet (1), the helmet (1) is to be connected through the hinge with face shield (5), face shield (5) can upper and lowerly overturn, maximum rotation angle is 90 °, face shield (5) is turned to upper and lower two limit positions, promptly when 0 ° or 90 °, an available latch or snap close fix face shield (5).The a pair of solar energy sheet E that is used for installing is arranged on face shield (5)
1(7) there is a pair of photoconductive resistance R that is used for installing solar energy sheet installation place (3)
1(9), R
2(10), R
3(11), R
4(12) photoconductive resistance installation place (4).Liquid crystal display LCD sheet (6) also is equipped with at face shield (5) middle part.Alkaline battery E
2(8) be contained in the battery case (2).
Liquid crystal display LCD sheet (6) is connected on the oscillating circuit pcb board (13) by lead, solar energy sheet E
1(7) and alkaline battery E
2(8) be connected in parallel on the oscillating circuit pcb board (13), liquid crystal display LCD sheet (6) is by solar energy sheet E
1(7) and/or alkaline battery E
2(8) provide power supply and drive variable color.The photoconductive resistance R of one group of parallel connection
1(9), R
2(10), R
3(11), R
4(12) be connected on alkaline battery E
2(8) and on the lead between oscillating circuit pcb board (13), when running into the hard arc light time, the photoconductive resistance resistance diminishes, turn-on power makes liquid crystal display LCD sheet (6) become dark color.
The utlity model has following advantage:
1, used heliotechnics, the alkaline battery consumption is few.
2, utilized the photo-electric control technology, made the LCD plate variable color, synchronous with electro-welding arc;
3, electric welder's helmet uses, preserves conveniently, both can improve electric welding efficient, can protect again electric welder's eyes;
4, simple in structure, with low cost;
5, because of being headgear type electric welding mask, during use, can protect the electric welder crown to avoid being injured by a crashing object by other falling objects.
