Description

Technical Field

[0001] The utility model relates to the technical field of welding tools, in particular to a handheld welding mask. Background Art

[0002] A welding mask is a tool that protects the safety of workers during welding and cutting operations, and it protects the eyes of operators when in use.

[0003] Most of the existing welding masks fix the welding goggles and welding glass pieces through patches. The operators observe the welding point processing position through the welding goggles and welding glass pieces to protect their eyes. However, when replacing the lenses, the iron sheet needs to be taken out because the iron sheet is relatively thin. Long-term use will cause the iron sheet to deform and bend, and thus the lenses cannot be fixed. The lens replacement is inconvenient because the two sides of the card slot for fixing the iron sheet are relatively protruding, and the lenses cannot be inserted from the front and need to be inserted from the top at an angle. The operation is relatively cumbersome and complicated for the operators. Utility Model Content

[0007] The utility model provides a handheld welding mask.

[0008] Furthermore, the front slot passes through the surface of the cover body and leaves a through cavity inside, and a rectangular protrusion is provided on the inner wall of the front slot.

[0009] Furthermore, a rectangular protrusion is provided on the top of the front slot, the connecting shaft is inserted into the rectangular protrusion, and grooves are provided on both sides of the rectangular protrusion to expose the internal connecting shaft, and a spring is sleeved on the surface of the connecting shaft exposed to the outside.

[0010] Furthermore, one end of the spring is connected to the front slot and the other end is connected to the rear cover plate, and the spring always pulls the rear cover plate to be in a vertical state with the front slot.

[0011] Furthermore, a front slot, a welding glass sheet, welding goggles and a rear cover plate provided with a rubber ring are sequentially arranged from the outside to the inside of the cover body.

[0012] Furthermore, the rear cover plate is in the form of a rectangular frame as a whole and extends into the interior of the front slot, and the welding glass sheet and the welding goggles are held between the front slot and the rear cover plate.

[0013] Furthermore, the bottom of the rear cover plate and the bottom of the front slot are provided with mutually matching press buckles.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model forms a through hole on the surface of the cover body through a front slot, and installs a rear cover plate through a connecting shaft on the top of the front slot. Under the action of a spring, the rear cover plate always keeps a vertical state with the front slot. After placing a welding glass sheet and welding goggles in the front slot, the rear cover plate is rotated along the connecting shaft so that the rear cover plate holds the welding glass sheet and the welding goggles between the two to form a fixation, and the position is fixed by pressing buckles at the front slot and the bottom of the rear cover plate to complete the installation. When replacement is needed, only the buckle needs to be opened, and the rear cover plate is automatically flipped up. The operator replaces the welding glass sheet and the welding goggles and then closes the rear cover plate again to complete the fixation so that they can continue to be used. The overall operation is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS
