Description

Technical Field

[0001] The utility model relates to the technical field of welding protective covers, in particular to a hands-free face protective cover for welding. Background Art

[0002] Electric welding refers to a welding method that uses electrical energy to achieve atomic bonding of welded parts. It is widely used in industry and daily life. During manual welding, a face shield is required to protect the eyes and face.

[0003] Traditional face shields need to be equipped with a handle. When welding, the worker holds the handle with one hand to hold the face shield and welds with the other hand. Wearable face shields are now available on the market, which do not require the worker to hold the face shield all the time. However, since the face shield needs to be equipped with dark lenses to protect the eyes, it is difficult to confirm the welding point through the dark lenses during welding. Therefore, the operator needs to frequently remove the shield to confirm the welding point, which affects the welding continuity and reduces the welding efficiency. For this reason, we propose a hands-free face shield for welding. Utility Model Content

The bottom surface of the lifting plate presses the control button to shrink the electric push rod and drive the eye shield to slide downward in the limiter through the connecting plate, so that the eye shield does not block the operator's eyes. At this time, the welding point can be clearly observed through the splash guard. It not only does not need to hold the protective shield body, but also does not need to frequently take off and put on the protective shield, which ensures the continuity of welding and improves welding efficiency.

[0014] 2. The hands-free face shield for welding can drive the threaded rod to rotate by turning the knob, thereby driving the connection block and the control button to move, changing the initial position of the control button, and adjusting it before welding to ensure that when the operator closes his mouth, the lifting plate contacts the control button, and when the operator opens his mouth, the lifting plate can be driven to press the control button. Its adjustable function is easy to adapt to different operators and improves the versatility of the shield. BRIEF DESCRIPTION OF THE DRAWINGS
