DETAILED DESCRIPTION

[0020] The application will be further described in detail below in combination with the drawings and specific embodiments.

[0021] As Figures 1-2 shown, a metal welding safety protection device, including for protecting the head guard plate 1, for protecting the face mask 2, the guard plate 1 and the mask 2 are integrally connected correspondingly, the guard plate 1 and the mask 2 are both arc-shaped structure, the mask 2 is the filter material, the lower side of the guard plate 1 is provided with head wearing assembly,

[0022] The head wearing assembly includes the guide rail 3 fixed correspondingly on the lower side of the arc-shaped guard plate 1, the lower side of the guide rail 3 is provided with the strap 4 for wearing positioning on the head, the outer side of the top of the strap 4 is fixed with the T-shaped sliding block 5, the sliding block 5 is slidably connected with the guide rail 3, the sliding of the sliding block 5 in the guide rail 3 is used for controlling the strap 4 to be close to or away from the mask 2, the lower side of the guard plate 1 is further fixed with the elastic air bag 6 for abutting against the head (optionally with the air nozzle, the structure can be externally connected to inflate).

[0023] Before wearing, the position of the sliding block 5 in the guide rail 3 needs to be adjusted, so that the distance between the mask 2 and the face after wearing meets the needs of the operator, for example, when the operator wears glasses, the mask 2 is adjusted to be far away from the face (so that the sliding block 5 is away from the mask 2 in the guide rail 3).

[0024] Then the strap 4 is used for wearing and positioning on the head, and the elastic air bag 6 is combined with the abutment on the head, so that the guard plate 1 can be firmly positioned with the head. The outward expansion of the elastic air bag 6 can press and position the sliding block 5 and the guide rail 3, so as to ensure the positioning of the whole protection device with the head of the operator, so that the guard plate 1 and the mask 2 can correspondingly move with the head of the operator, and the stable protection during welding operation is ensured.

[0025] After wearing the device, there is enough gap between the guard plate 1 and the head, and there is enough gap between the mask 2 and the face, so as to ensure sufficient air circulation, so that the operator will not be suffocated even if wearing for a long time, and the comfort is improved. Of course, the device will not affect the operator wearing the protective mask, and is more flexible to use.

[0026] As Figure 1 shown, the end of the guide rail 3 is provided with the open mouth 7 for moving out the sliding block 5. By moving out the sliding block 5, part of the strap 4 can be removed, which is conducive to the disassembly and storage of the device or the replacement of the strap 4, and improves the convenience of use.

[0027] As shown in Figures 1-2 , the slider 5 is made of magnet material; the inside of the guide rail 3 is fixed with a ferromagnetic connecting piece 8 along the length direction; the slider 5 is magnetically connected with the connecting piece 8. The slider 5 is magnetically connected with the connecting piece 8, which can realize relative positioning of the harness 4 and the guard plate 1 before wearing, effectively preventing the slider 5 from moving in advance when taking the device to wear.

[0028] As shown in Figure 1 , the harness 4 includes an elastic expansion band 9 placed on the head and a binding band 10 placed on the lower jaw; the two ends of the elastic expansion band 9 are connected through the binding band 10; the slider 5 is fixed on the elastic expansion band 9. When the binding band 10 is positioned on the lower jaw of the user, the elastic expansion band 9 can be appropriately tightened to improve the firmness of wearing by using the elastic force.

[0029] As shown in Figure 1 , the outer sides of the two ends of the binding band 10 are respectively fixed with mounting pads 11; the mounting pads 11 are connected with spring tightening buckles 12; the end of the guard plate 1 away from the mask 2 is connected with two safety ropes 13; the two safety ropes 13 are respectively located on the two sides of the head and are connected with the spring tightening buckles 12 on the same side. The spring tightening buckles 12 can adjust the tension of the safety ropes 13 to adapt to the position changes between the harness 4 and the guard plate 1. Through the pulling of the safety ropes 13 on the rear part of the guard plate 1, the gravity of the other end mask 2 is balanced, avoiding the problem that the guard plate 1 easily slides to the facial direction, improving the reliability of use.

[0030] As shown in Figure 1 , the end of the guard plate 1 close to the mask 2 is connected with a micro fan 14; the air outlet of the micro fan 14 faces the area between the mask 2 and the face of the wearer. The micro fan 14 can blow a breeze between the face and the mask 2 (selecting appropriate power to avoid too large air flow), improving the air flow in this area, further reducing the problem that the mask 2 blocks the breathing of the worker and makes him feel suffocated.

[0031] As shown in Figure 1 , the end of the guard plate 1 away from the mask 2 is connected with a protective film 15 for shielding the back of the wearer's head. The protective film 15 can shield the splashing objects that bounce back to the back of the head after collision, improving the comprehensiveness of protection. The protective film 15 can be made of high-temperature-resistant material, such as composite film material with aluminum film on the surface.

[0032] It is to be understood that the present application is described by way of example only, and that modifications or alterations can be made to the features and embodiments described without departing from the spirit and scope of the application. In addition, modifications can be made to the features and embodiments described to accommodate specific situations and materials without departing from the spirit and scope of the application. Accordingly, the application is not limited to the specific embodiments disclosed herein, but rather, the scope of the application includes all embodiments falling within the scope of the claims.
