[Document 1] Domestic Utility Model Model No. 20-0080146, 1994.05.17.

In general, when using a welding device for welding operations such as arc welding, gas welding, and other cutting, the face protection unit that covers the face and neck to protect the face and neck, and is installed in the center of the face protection unit Wear a welding mask consisting of a see-through section consisting of a shading window and a transparent window to block the light.

Such a welding mask is roughly divided into a hat-type mask fixed to the head, such as a hat, and a handle-integrated mask covering the face while being held by hand with a handle.

Since the hat-type mask should be removed and worn like a hat, it is used when it is necessary to use both hands in a work environment with sufficient free space. The handle integrated mask is used when the working space is very narrow and sufficient work is possible with one hand in a working environment where the mask cannot be taken off and worn like a hat.

At this time, the hat-shaped mask is provided with a device for releasing the light shielding window of a dark color in order to confirm the welding base material or the welding state, but the handle-integrated mask is not provided with a device for releasing the light shielding window.

When wearing a hat-type mask, one hand is free except for the hand holding the welding jig, so that the device for releasing the shading window can be operated. Because you hold the handle, both hands are not free.

Therefore, when performing a welding operation using the integrated handle mask, the mask that covers the face should be removed from the face every time when checking the welding base material or the welding state, there was a very uncomfortable use.

In particular, in a work environment in which the space is very narrow and it is difficult to move the mask sideways, the welding base material or the welding state must be checked in a state in which the shading window is not released.

The present invention has been invented to solve the above problems, in order to make it easier to visually check the welding base material or welding state when performing a welding operation using a welding mask equipped with a handle integrally, neck A face protector surrounding the face to protect the face, including; A see-through unit installed in the center of the face protection unit and configured to include a shielding window that blocks harmful rays and a transparent window that is replaceably installed on the front side of the shielding window to protect the shielding window; A handle portion provided on the front lower side of the face protector; In constructing a handle integral welding mask comprising a sliding frame, the shading window is connected to the release lever installed in the handle portion through a connector to slide vertically and vertically in the release space partitioned below the see-through section and see-through section Is installed in, the sliding frame is aimed to provide a welding mask installed to be elastically supported by the return spring, one end is fixed to the lower side of the release space portion to be always elastically positioned toward the see-through portion.

Since the welding mask of the present invention can release the light shielding window of the see-through part very conveniently and can also replace the see-through part very easily, there is an effect of enabling the operator to perform the welding work more efficiently.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the present invention, FIG. 2 is a vertical sectional view of the present invention, FIG. 3 is a sectional view taken along the line “A-A” of FIG. 2, and FIG. 4 is a vertical sectional view of the light shielding window of the present invention being released.

The welding mask 100 of the present invention includes a face protection unit 1 surrounding the face to protect the face including the neck; A transparent window (3) installed at the center of the face protection unit (1) to block harmful light rays and a replaceable part installed at the front of the light shield (2) to protect the light shield (2) And a see-through section 4 composed of); A handle portion 5 installed on the front lower side of the face protector 1; In constructing a handle integral welding mask comprising a, the light shielding window (2) is configured to be lowered down the see-through portion 4 through the operation of the release lever (6) installed on the handle portion (5). It features.

The transparent window (3) is supported by a blotting frame (7) that is rotated up and down for easy replacement.

The welding mask 100 of the present invention configured as described above is a protective tool used to protect the face including the head and neck from welding debris and the like while protecting the eyes from harmful light generated when performing a welding operation.

In particular, the welding mask 100 of the present invention can release the light shielding window 2 in a state in which the handle part 5 is integrally held and the handle part 5 is held by the hand. It is a big feature that can be made more convenient.

As shown in FIGS. 1 and 2, the sliding frame 8 installed around the light shielding window 2 to install the light shielding window 2 on the see-through part 4 is connected to the handle part 5 through the connector 9. It is connected to the release lever 6 installed in the) is installed so as to slide up and down in the interior of the release space 10, which is integrally partitioned below the see-through portion 4 and the see-through portion 4, the sliding frame ( 8) is due to the structure installed so as to be elastically supported by the return spring 11 so that when the handle (5) there is no operation of the lifting and sliding to the side of the see-through portion (4).

That is, when the release lever 6 installed on the handle portion 5 is pulled down, the sliding frame 8 is lowered toward the release space portion 10 under the seeing portion 4 while the light shielding window 2 is the see-through portion 4. It is by the structure which can confirm a welding base material or a welding state through the transparent window 3 of the see-through part 4 by releasing from).

Therefore, when the worker wants to release the shading window 2 in order to check the welding base material or the welding state during the welding operation, the release lever 6 is pushed down by using the thumb of the hand holding the handle 5. You just need to give it.

Then, as shown in FIG. 4, the sliding frame 8 connected to the handle part 5 by the connector 9 is lowered from the perspective part 4 to the release space part 10 under the perspective part 4. The return spring 11 elastically supporting the sliding frame 8 is in a compressed state.

Accordingly, since the light shielding window 2 is released from the see-through part 4 so that only the transparent window 3 exists, the welding base material or the welding state is easy even if the face protection part 1 is not removed from the face as described above. It can be confirmed.

When the welding work is to be continued after confirming the welding base metal or the welding state as described above, the sliding frame 8 may be regenerated by the elastic return force of the return spring 11 simply by releasing the thumb from the release lever 6. Return to the see-through portion 4, which is the position of the welding operation can proceed immediately.

Therefore, the handle integrated mask 100 which is mainly used in a narrow working space can be used more conveniently, and thus the welding operation can be performed more effectively.

Here, as shown in Figure 3, the transparent window 3 is installed on the front of the see-through portion 4 so that the upper end is rotated, and the lower end is inserted into the fastening groove 12 provided in the see-through portion 4 in a force-fitting manner. The fastening jaw 13 has a structure that is supported inwardly by the holding paper frame 7 protruding.

Therefore, when welding debris or the like is attached to the transparent window 3 during the welding operation and the welding field cannot be secured, and the transparent window 3 is to be replaced, the paper press frame 7 is opened, the transparent window 3 is replaced, and the paper is pressed again. Since the frame 7 is to be closed, the replacement operation of the transparent window 3 can be made very convenient.
