Description

Welding mask

technical field

The utility model relates to an electric welding mask, in particular to the structure that the goggles of the electric welding mask have two kinds of transparent lenses with different colors. the

Background technique

Electric welding is a mechanical processing method that uses a large amount of current to pass through two poles at a certain distance, that is, the arc phenomenon generated at the end point generates high heat, and makes the metal parts or materials at the hot spot welded to each other. In the construction process of electric welding, strong arc light damage will be produced, and high-temperature hot solder or metal scraps will be splashed. Therefore, if the welder performs the above-mentioned electric welding construction, he must be equipped with a welding mask. The goggles protect the eyes so that the eyes will not be hurt by strong light, and at the same time, the face will not be scalded by spraying solder and metal shavings, so as to maintain the safety of construction. the

However, the lenses contained in the visor lens group used by the existing commonly used welding masks are all black lenses, so when welding, the welder must cover his face with the welding mask for welding for a while, and remove the welding mask completely for a while. , After seeing the welding result clearly, the welding work is completed repeatedly. However, such a working method is too inefficient, and it is easy to cause fatigue to the welder. Therefore, the industry has developed the prior art disclosed in Taiwan New Patent No. M338648 "Structure Improvement of Welding Mask". When welding, it is necessary to cover the transparent lens with a black lens for a while to isolate the strong light of the arc during welding work, and to turn over the dark lens for a while to see the welding result, and so on to complete the welding work. However, this working method is still quite It is troublesome, and the improvement of work efficiency is still limited and needs to be improved. the

In view of the shortcomings of the above-mentioned background technology, the designer of the utility model has developed a new type of electric welding mask through years of research. Therefore, the main purpose of the present invention is: a kind of electric welding mask that can improve welding work efficiency. the

In order to achieve the above object, the technical solution adopted by the utility model is:

An electric welding mask, which is a cover body with a perforation, and a goggle set is connected around the perforation. Place a dark colored lens and a transparent lens, wherein a partition extending forward is provided between the dark colored lens and the transparent lens, and a frame is connected to the partition to form a mirror cover. The shape and position of the mirror cover Corresponding to the mirror base, a fastening device is provided between the mirror base and the mirror cover. the

The electric welding mask, wherein: the mask is provided with wearing parts. the

Said electric welding mask, wherein: the mirror base is set to be uniformly thick in the upper half, and gradually thinner in the lower half. the

Said electric welding mask, wherein: the partition is inclined forward and downward. the

Said electric welding mask, wherein: the partition plate extends upwards with a protrusion, and the protrusion is embedded between the dark colored lens and the transparent lens. the

Said electric welding mask, wherein: two side plates are arranged on both sides below the partition. the

Said electric welding mask, wherein: the dark lens is arranged above the partition, and the transparent lens is arranged below the partition. the

Said electric welding mask, wherein: the dark lens is arranged below the partition, and the transparent lens is arranged above the partition. the

The electric welding mask, wherein: an elastic body is arranged between the dark lens, the transparent lens and the mirror cover. the

Therefore, compared with the background technology, the utility model has the following effects: the goggle set of the utility model is indirectly provided with a partition inclined downward in the through hole of a frame, and the top of the partition is installed There is a black lens, and a transparent lens is installed under the partition. When electric welding work is being performed, the eyeballs can be combined with the dark lens to form a line of sight. If you want to see the welding results or move to other places for welding, you can look up and look at it. Turn its eyeballs downward to form a line of sight with the transparent lens. Or a transparent lens is installed on the top of the partition, and a black lens is installed on the bottom of the partition. When the welding work is performed, the head can be raised and the eyeballs can be lowered to match the black lens to form a line of sight. If you want to see the welding results or move to another place for welding, you can lower your head and turn your eyes to look at the eye level with the transparent lens. Therefore, the utility model has two different modes, which can be used with the lens according to the suitable mode for each person. During its welding work, there is no need to remove the entire electric welding mask, so as to improve the efficiency of electric welding work. the

Detailed ways

In order to achieve the above purpose and effect, the specific technical means used by the utility model are further described in detail. the

First of all, please refer to Fig. 1 to Fig. 3, which is a kind of electric welding mask provided by the utility model, comprising: a cover body 1 and a goggle group 2; wherein,

The cover body 1 is made of flame-resistant and opaque material, and can completely cover the welder's head and face, so that the cover body 1 can cover the strong light generated during electric welding work and the sprayed radiation. High-temperature molten metal and solder, and the upper inner side of the cover 1 is provided with a wearing piece 13 to wear on the head of the electric welder, and the cover 1 is provided with a perforation 11 corresponding to the eyes of the welder, and the perforation 11 A mirror holder 12 is fixed or integrally formed inside, and the mirror holder 12 is hollow in conjunction with the perforation 11 and is provided with a lens placement place 121 for placing a black lens 24, a transparent lens 25 and an elastic body 27. 12 is set to be uniformly thick in the upper half, and gradually thinner in the lower half; and
