Description

Technical Field

[0001] This utility model relates to the field of welding helmet technology, specifically a safety welding helmet with nighttime warning function. Background Technology

[0002] A welding helmet is a protective helmet worn by welding workers. It is generally equipped with a protective mask with goggles. Its structure is relatively simple and its function is relatively single. In actual use, especially at night when there is little or no lighting, and the construction site is relatively complex, welding helmets lack obvious markings and are easily overlooked during construction. They cannot provide clear warnings or indications for the workers wearing them. In the construction site, the lack of clear indications can easily lead to dangerous accidents. In particular, the strong light generated by welding can cause great irritation to the eyes of workers around the welding site. When welding is not in progress, the area around the welding position is often overlooked, posing a significant safety hazard.

[0003] Chinese patented invention CN218389922U discloses a nighttime warning light safety welding helmet, relating to the field of welding helmet technology. This invention includes an inner helmet body and an outer helmet body. A protective face shield is rotatably connected to the outer helmet body. A padding layer is provided inside the inner helmet body. A mounting base is fixed to the top of the inner helmet body, penetrating the outer helmet body and extending to the top of the outer helmet body. A warning light is fixed to the top of the mounting base by screws. This invention, by installing a mounting base on the top of the inner helmet body and mounting a warning light on the mounting base, provides a location display function for construction workers wearing welding helmets during use, releasing warning signals to the surroundings. Simultaneously, it facilitates the installation and replacement of the warning light without requiring the welding helmet to be replaced along with it, ensuring the safety of construction workers while reducing operating costs.

[0004] However, the device still has some problems. In actual use, the warning light is installed on the mounting base with screws. When the warning light is damaged and needs to be removed for repair, it is not convenient to remove it quickly. Tools are needed to remove the screws. At the same time, the screws are prone to damage after long-term use, which affects the disassembly and assembly work. Therefore, we propose a safety welding cap with night warning function to solve the above problems. Utility Model Content

[0021] Example

[0022] Please see Figure 1-5This utility model provides a technical solution: a safety welding helmet with nighttime warning function, comprising a welding helmet body 1, a rectangular box 2 fixedly connected to the top of the welding helmet body 1, a rectangular plate 3 movably contacting the top of the rectangular box 2, a warning light 4 fixedly connected to the top of the rectangular plate 3, two L-shaped seats 5 fixedly connected to the bottom of the rectangular plate 3, the bottom of the L-shaped seats 5 extending into the rectangular box 2 and movably contacting the inner wall of the bottom of the rectangular box 2, the rectangular box 2 slidably fitted on the outside of the two L-shaped seats 5, a limiting block 6 and an arc-shaped block 7 fixedly connected to the inner wall of the L-shaped seats 5, a square rod 8 slidably connected between the limiting block 6 and the corresponding arc-shaped block 7, a ball bearing 9 embedded at the end of the square rod 8, the ball bearing 9 cooperating with the arc-shaped surface of the corresponding arc-shaped block 7, a connecting rod 10 rotatably connected to the top of the square rod 8, the two connecting rods 10 being symmetrically arranged. The top of the connecting rod 10 is rotatably connected to a crossbar 11. When the rectangular block 12 moves downward, it presses the connecting rod 10 through the crossbar 11. The connecting rod 10 drives the ball bearing 9 to move out from between the corresponding limiting block 6 and the arc-shaped block 7 through the square rod 8. At this time, the warning light 4 can be moved upward to remove it for maintenance. During installation, the warning light 4 moves downward and drives the arc-shaped block 7 to move through the L-shaped seat 5. The arc-shaped block 7 presses the ball bearing 9. During the movement, the square rod 8 compresses the spring 16. When the arc surface of the arc-shaped block 7 is misaligned with the ball bearing 9, the elastic force of the spring 16 drives the square rod 8 to move between the limiting block 6 and the arc-shaped block 7, thus completing the installation of the warning light 4. When the warning light 4 is damaged and needs to be removed for maintenance, it is easy to remove it quickly without the need for tools to remove the screws, which makes the disassembly and assembly work convenient.

[0023] In this embodiment, specifically: the two crossbars 11 are fixedly connected to the same rectangular block 12 at their close ends, and a rectangular hole 13 is provided on the inner wall of the front side of the rectangular box 2;

[0024] In this embodiment, specifically: the front side of the rectangular block 12 passes through the rectangular hole 13 and extends to the outside of the rectangular box 2, and the outer side of the rectangular block 12 is slidably connected to the inner wall of the rectangular hole 13.

[0025] In this embodiment, specifically: two vertical rods 14 are fixedly connected between the top inner wall and the bottom inner wall of the rectangular box 2, and the horizontal rod 11 is slidably sleeved on the outside of the corresponding vertical rod 14;

[0026] In this embodiment, specifically: a positioning rod 15 is fixedly connected to the outside of the vertical rod 14, the square rod 8 is slidably sleeved on the outside of the corresponding positioning rod 15, and the end of the square rod 8 is fixedly connected to the corresponding vertical rod 14 with the same spring 16.

[0027] In this embodiment, specifically: the spring 16 is movably sleeved on the outside of the corresponding positioning rod 15, and the outer side of the welding cap body 1 is rotatably connected to the protective cover 17;

[0028] In this embodiment, specifically: two elastic bands 18 are fixedly connected to the bottom of the welding cap body 1, a male Velcro 19 is fixedly connected to the outer side of the rear elastic band 18, and a female Velcro 20 is fixedly connected to the outer side of the front elastic band 18.

[0029] In operation, this utility model allows the welding cap body 1 to be worn on the user's head by the cooperation of the male Velcro 19 and the female Velcro 20. The warning light 4 serves as a warning at night. When the warning light 4 needs to be removed for maintenance after prolonged use, the rectangular block 12 is grasped and moved downwards. The rectangular block 12 slides downwards within the rectangular hole 13, causing the two horizontal bars 11 to move. During the movement, the horizontal bars 11 press against the connecting rod 10. Under the pressure, the connecting rod 10 moves and rotates, causing the corresponding square rod 8 to move. The square rod 8 slides outside the corresponding positioning rod 15, compressing the spring 16 during its movement. The square rod 8 moves the ball bearing 9, and moves out from between the corresponding limiting block 6 and the arc-shaped block 7. At this time, the warning light 4 is moved upwards, causing the rectangular plate 3 to move. The rectangular plate 3 moves the L-shaped seat 5, which moves out from the rectangular box 2. At this time, the damaged warning light 4 can be removed for maintenance.

[0030] During installation, the warning light 4 is moved downwards, causing the rectangular plate 3 to move. The rectangular plate 3 then moves the L-shaped seat 5, which moves into the rectangular box 2. The L-shaped seat 5 then moves the arc-shaped block 7. During the movement, the arc-shaped surface of the arc-shaped block 7 presses against the ball bearing 9. Under the pressure, the ball bearing 9 moves the square rod 8, which slides on the outside of the corresponding positioning rod 15. During the movement, the square rod 8 compresses the spring 16. When the arc-shaped surface of the arc-shaped block 7 is misaligned with the ball bearing 9, the spring 16, which is in a compressed state, returns to its original position. The elastic force of the spring 16 moves the square rod 8, causing it to move between the corresponding limit block 6 and the arc-shaped block 7. This completes the installation of the warning light 4, thus forming a safety welding cap with a nighttime warning function. When the warning light 4 is damaged and needs to be removed for repair, it can be quickly removed without the need for tools to remove the screws, making disassembly and assembly easier.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
