Description

Technical Field

[0001] This utility model relates to the field of welding protective gear technology, specifically a welding mask with a flexible liquid crystal display screen. Background Technology

[0002] Welding masks play multiple crucial roles in welding operations. First, they provide comprehensive protection for the face and eyes, effectively blocking strong ultraviolet, infrared, and visible light radiation, preventing damage to the welder's eyes and skin. Second, welding masks are equipped with adjustable shading plates, allowing welders to select the appropriate shading level based on different welding currents and materials, ensuring a clear and safe field of vision under various conditions, thereby improving welding accuracy and efficiency. In addition, welding masks can prevent burns to the welder's face and neck from splattered welding slag and sparks, protecting the welder's safety and health, and enhancing the overall safety and comfort of the operation.

[0003] In the existing technology, traditional welding masks consist of a mask shell, a light shield, and a headband. The mask shell provides physical protection; the light shield blocks harmful light; and the headband ensures that the mask is worn securely. These components work together to protect the welder's eyes and face.

[0004] However, in the use of traditional welding masks, the main light-shielding component is achieved through light-shielding sheets, which have poor light-shielding effect and can damage the operator's eyesight. Therefore, this utility model proposes a welding mask with a flexible liquid crystal display screen to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 5 The present invention provides a technical solution: a welding mask with a flexible liquid crystal display screen, the welding mask with a flexible liquid crystal display screen includes: a protective mask 1, an elastic band 2 provided on the surface of the protective mask 1, and a handle 3 installed at the bottom of the protective mask 1;

[0023] A fixed frame 4 is provided, a transparent protective plate 5 is installed at one end of the fixed frame 4, a positioning plate 6 is installed behind the transparent protective plate 5, and an LCD display 7 is provided between the positioning plate 6 and the transparent protective plate 5.

[0024] When in use, the welding mask can be placed directly in front of the operator's face using the elastic band 2 on the surface of the protective mask 1 or the handle 3 below. When the LCD 7 senses that welding is in progress, the LCD 7 will respond quickly and reduce the transmittance of the LCD 7 rapidly to protect the user's eyes from strong light damage. This avoids the problem of vision damage caused by poor light shielding.

[0025] Example 2: Based on Example 1, a liquid crystal display (LCD) 7 is provided to better protect the operator's eyes. The LCD 7 consists of a photoelectric sensor 16, an LCD panel 17, a mounting housing 18, and a solar panel 19. The photoelectric sensor 16 is electrically connected to the solar panel 19, and the solar panel 19 is electrically connected to the LCD panel 17. The outer wall of the LCD 7 is attached to the inner wall of the fixing frame 4. During welding, when the photoelectric sensor 16 on the LCD 7 detects the change in light generated during welding, it transmits this signal to the solar panel 19. The solar panel 19 quickly responds and drives the LCD panel 17 to rapidly reduce the light transmittance, thereby better protecting the operator's eyes.

[0026] Example 3: Based on Example 2, a lower protrusion 9 is provided for easier use. A fixing block 12 is fixedly installed on the inner wall surface of the lower protrusion 9. A threaded hole is opened at the bottom of the fixing block 12, and a connecting rod 13 is screwed into the threaded hole. A protective frame 14 is fixedly installed at the lower end of the connecting rod 13, and a handle 3 is inserted into the protective frame 14. The protective mask 1 has an overall arc structure. An upper protrusion 8 is provided at the upper end of the protective mask 1, and a lower protrusion 9 is provided at the lower end of the protective mask 1. Grooves 10 are opened on both sides of the protective mask 1. The surfaces of the grooves 10 on both sides are fixedly connected to the two ends of the elastic band 2. An installation frame 11 is fixedly connected to the surface of the protective mask 1. During electric welding, the operator can hold the mask in front of the protective position through the handle 3, or the handle 3 can be removed from the bottom surface of the lower protrusion 9 and the mask can be worn on the face through the elastic band 2. It has multiple ways of use, which makes it convenient for the operator to use the mask.

[0027] The fixing frame 4 is a rectangular parallelepiped structure. The outer wall surface of the fixing frame 4 is fixedly connected to the inner wall surface of the mounting frame 11. The inner wall of the mounting frame 11 has slots 15 on both sides. The positioning plate 6 has sliding grooves 22 on both sides. A slider 20 is inserted into the sliding groove 22 and can move within it. A square hole is formed on the upper surface of the sliding groove 22. Two sets of springs 21 are fixedly installed on the surface of the sliding groove 22 away from the inner wall of the fixing frame 4. One end of each spring 21 is fixedly connected to one side of the slider 20. A retaining plate 23 is fixedly connected to the side of the slider 20 away from the springs 21. The retaining plate 23 can be inserted into the slots 15. An auxiliary... The auxiliary plate 24 is inserted into a square hole. The positioning plate 6 has a square hole on its surface, and a transparent protective plate 5 is fixedly installed in the square hole. During installation, the LCD display 7 is placed between the transparent protective plate 5 and the positioning plate 6 at one end of the fixing frame 4. By applying force to the auxiliary plates 24 at both ends of the positioning plate 6 to bring them closer together, the locking plate 23 at one end of the slider 20 is disengaged from the slot 15. At the same time, an upward pulling force is applied to the positioning plate 6 as a whole to remove the positioning plate 6 from the fixing frame 4. This allows the LCD display 7 to be removed from the fixing frame 4 for easy replacement or repair, thus making it easier to use the cover.

[0028] Working principle: In actual use, the welding mask can be placed directly in front of the operator's face through the elastic band 2 on the surface of the protective mask 1 or the handle 3 below. When the LCD 7 senses that welding is in progress, the LCD 7 will respond quickly and reduce the transmittance of the LCD 7 rapidly to protect the user's eyes from strong light damage. This avoids the problem of vision damage caused by poor light shielding.
