Abstract

(57) [Summary] [Objective] This invention is a welding protection surface in which a light shielding lens is slid on the transparent glass of the observation window. [Structure] The light-shielding lens slide rails 6 are attached to both sides of the transparent glass 3 of the observation window, and the light-shielding lenses 4 are fitted along the rails. The connecting lot 7 and the slide lever 2 are attached to the light blocking lens 4. When the slide lever 2 is pulled down, the light blocking lens 4 is lowered, and when returning to the original position, a return spring 5 and a connecting lot 7 are provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a welding protection surface in which a light-shielding lens on the welding protection surface is slid by a slide lever.

[0002]

[Prior art]

 Conventionally, the light-shielding lens on the welding protection surface has been a fixed type.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. Since a light-shielding lens was fixed on the conventional welding protection surface, the position of the welding material and the welding rod could not be confirmed except during arcing of the welding rod during welding work. Therefore, the welding position of the welding material and the welding rod could not be confirmed unless the welding protection surface was removed from the face. After confirming the position, it was put on the face again, but at this time the welding position was misaligned, and welding mistakes and workability were poor. The present invention has been made to eliminate the drawback.

[0004]

[Means for Solving the Problems]

 This is a welding protection surface in which a light-shielding lens slides on the transparent glass of the observation window of the welding protection surface. The present invention is a welding protection surface having the above configuration.

[0005]

[Work]

 Attach the light-shielding lens slide rails 6 to both sides of the transparent glass 3 of the peep window, and fit the light-shielding lens 4 along the rails. Attach the connecting lot 7 and slide lever 2 to the light-shielding lens 4. When the slide lever 2 is pulled down, the light-shielding lens 4 is lowered, and to return it to the original position, a return spring 5 and a connecting lot 7 are provided.

[0006]

[Example] When the user holds the handgrip 1 and pulls the slide lever 2 downward with his / her finger, the light blocking lens 4 is moved downward by the connecting lot 7 and the welding position can be confirmed from the transparent glass 3. At the start of work, if you remove your finger from the slide lever, the return spring 5 will return the light-shielding lens to the top and protect your eyes from the arc.

[0007]

[Effect of device]

 Since a series of welding operations can be performed without removing the welding protection surface from the face, there is no displacement of the welding location and safe, quick and accurate operations can be performed, and workability is improved.
