[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figure 1-4 This invention discloses an automatic shading and eye protection device for a welding helmet. A protective panel 101 is fixedly connected to the left side wall of the helmet body 100, facilitating face protection. A lens frame 102 is fixedly connected to the inner wall of the protective panel 101, supporting a slide 103. Slides 103 are fixedly connected to both the left and right side walls of the inner cavity of the lens frame 102, guiding and limiting the movement of a lifting frame 104. Lifting frames 104 are slidably connected to the inner cavities of the slides 103, supporting the shading lens 106. The inner cavity of the lifting frame 104 is slidably connected with a counterweight 105. The impact force of the sliding counterweight 105 facilitates the movement of the lifting frame 104. The opposite side walls of the two sets of lifting frames 104 are fixedly connected with a light-shielding lens 106. The light-shielding lens 106 facilitates light shielding during welding and protects the eyes. The upper side of the opposite side wall of the inner cavity of the left and right slides 103 is fixedly connected with an elastic card 107. The elastic card 107 will deform under pressure and can be easily locked into the inner cavity of the card slot to limit the lifting frame 104. The upper side of the opposite side wall of the left and right lifting frames 104 is provided with a card slot.

[0022] In this embodiment: The cap 100 is worn on the worker's head during use. The protective panel 101 protects the worker's face. When welding is required, a nodding motion causes the counterweight 105 to slide within the lifting frame 104. The counterweight 105 then moves downwards and impacts the lifting frame 104, causing it to move downwards. This causes the elastic card 107 to deform and disengage from its slot, resulting in the lifting frame 104 moving the sunshade lens 106 downwards. This facilitates eye protection during welding. Alternatively, the nodding motion can also cause the counterweight 105 to slide downwards. 05 moves upward, and the counterweight 105 moves upward to impact the lifting frame 104, causing the elastic card 107 to deform. The elastic card 107 engages with the slot, which helps to limit the lifting frame 104. The lifting frame 104 drives the light-shielding lens 106 to move upward, preventing the light-shielding lens 106 from obstructing light transmission and making it easier for personnel to view the welding area. This device can make it easy to provide light protection for the eyes during welding and to allow light to pass through when not welding, freeing up the hands, improving the work efficiency of the workers, and avoiding affecting the welding quality.

[0023] Protective lenses 108 are fixedly connected to the left and right side walls of the inner cavity of the eyeglass frame 102. The protective lenses 108 facilitate the sealing of the eyeglass frame 102. The protective lenses 108 are located on the left and right sides of the light-blocking lens 106.

[0024] In this embodiment: the protective lens 108 facilitates the sealing of the inner cavity of the frame 102, preventing dust and impurities from entering the inner cavity of the frame 102 and avoiding contamination of the light-shielding lens 106, which would affect subsequent viewing. This allows the device to seal the inner cavity of the frame 102, preventing contamination of the light-shielding lens 106 and making it difficult to clean, and also facilitates the adjustment of the angle of the light-shielding lens 106.

[0025] The right side wall of the frame 102 is fixedly connected to the lens holder 109, which makes it easy to wear the glasses in a close fit to the face. The lens holder 109 is made of silicone material.

[0026] In this embodiment: by setting the lens holder 109, it is convenient for users to wear the device and to support the frame 102. This makes the device fit the face more comfortably when worn, avoids shaking of the device when worn, and helps to support the frame 102.

[0027] An elastic band 110 is fixedly connected to the right side wall of the protective panel 101, which is convenient for binding to the head. The protective panel 101 is arc-shaped.

[0028] In this embodiment: when wearing, the elastic band 110 is tied to the head for stable wearing, to prevent it from falling off during use and to improve stability. The arc-shaped protective panel 101 is easy to fit the face and is beneficial for protection.

[0029] The top walls of the lifting frame 104 are all arc-shaped, and the inner walls of its card slots are also arc-shaped, with the elastic card 107 matching the card slot.

[0030] In this embodiment, the arc-shaped design facilitates the deformation of the elastic card 107, making it easy for the elastic card 107 to be snapped into the card slot. This facilitates the addition of the light-shielding lens 106, making it easier to provide light protection during the welding process and also making it easier to inspect the weld seam when not welding.
