Description

Technical Field

[0001] The utility model belongs to the technical field of protective helmets, in particular to a double-protection-shield welding helmet. Background Art

[0002] Welding helmets are used in the field of electric welding machines to provide reasonable protection for workers and prevent injuries to their heads, faces and eyes. Welding helmets generally include a main body and a welding mask. When welding, the welding mask needs to be lowered to cover the face of the human body. This protects the face and eyes of the human body.

[0003] For example, the Chinese patent document with publication number CN218784485U discloses a welding protective device with an adapter, including a mask and a bracket, a protective lens is embedded in the front of the mask, the bracket is connected to a bridge arm by rotating through knob 1, the bridge arm is rotatably connected to the mask through knob 2, and the bracket, bridge arm, knob 1 and knob 2 are combined to form an adapter. Through the setting of the mask, the two brackets are installed on the rotating shafts on both sides of the safety helmet, the safety helmet can be worn on the head of the welder, the angle between the bracket and the bridge arm can be adjusted by knob 1, the tilt angle of the mask can be adjusted by knob 2, the mask can be set on the face of the welder, and then the mouth, nose, eyes and all parts of the head of the welder can be covered in the welding protective device with an adapter, thereby improving the protective effect, and the head-mounted design improves the convenience of use, which is conducive to use in special environments.

[0004] For welders, they have to perform many tasks during the actual work process; for example, the workpiece needs to be cut and polished after welding. During welding, the protective mask used needs to filter light to prevent light from hurting the eyes of the workers. During grinding and polishing, the protective glasses of the welding mask will block the workers' vision, so the workers need to flip the protective mask up, which will not protect the workers.

[0026] In an embodiment of the double-shield welding helmet of the present utility model, please refer to Figure 1 , Figure 2 and Figure 6 ; The double-shield welding helmet of this embodiment is used for electric welding protection, which can protect the head, face and eyes of the staff, and can also play a protective role when the staff grinds the workpiece, and at the same time has a good line of sight effect. Specifically, the double-shield welding helmet includes a helmet main body 100, a welding mask 200 and a protective mask 300. The welding mask 200 is provided with a filter lens to avoid the dazzling light of welding from irritating the eyes. Connecting shafts 110 are respectively provided on both sides of the helmet main body 100. First connecting portions 310 extend from both sides of the protective mask 300, and the first connecting portions 310 are rotatably connected to the corresponding connecting shafts 110. The protective mask 300 is provided with a transparent plate 301. Second connecting portions 210 extend from both sides of the welding mask 200, and the second connecting portions 210 are rotatably connected to the corresponding connecting shafts 110, and the protective mask 300 is located inside the welding mask 200. In this embodiment, after the staff finishes welding the workpiece, the welding mask 200 can be turned up around the connecting shaft 110, then the protective mask 300 can play a protective role for the staff and maintain a good line of sight, and can play a protective effect on the staff during the cutting and grinding process.

[0027] Furthermore, please refer to Figure 2 and Figure 3, a threaded hole 111 is provided at the end of the connecting shaft 110, a locking screw 120 is connected in the threaded hole 111, and a limiting portion 121 is provided at the end of the locking screw 120 for limiting the first connecting portion 310 and the second connecting portion 210.

By supporting the second connecting portion 210 with the supporting rib plates 122, when the welding mask 200 is turned up, the friction can be reduced and the protective mask 300 will not be affected at the same time.

[0029] Further, referring to Figures 2 to 7 , a sleeve 312 extends inside the first connecting portion 310, and the first connecting hole 311 penetrates through the sleeve 312. A limiting sleeve 320 is arranged inside the sleeve 312, and the limiting sleeve 320 is arranged on the connecting shaft 110; a plurality of limiting grooves 321 are provided on both sides of the limiting sleeve 320, and engaging teeth 101, 201 are provided on the outer side of the helmet body 100 and the inner side of the welding mask 200, and the engaging teeth are engaged with the corresponding limiting grooves 321. So that the protective mask 300 is relatively fixed to the helmet body 100, and the welding mask 200 is relatively fixed to the protective mask 300. When the welding mask 200 is turned up, the engaging tooth 201 on the inner side of the second connecting portion 210 is disengaged from the corresponding limiting groove 321 and is engaged with another limiting groove 321, so as to re-position and fix the welding mask 200. When it is necessary to turn up the protective mask 300, the limiting grooves 321 engaged with the engaging teeth 101 on the helmet body 100 are separated from each other and are engaged with the next engaging tooth 101.

[0030] Further, referring to Figure 4 and Figure 6, the protective face shield 300 includes a frame body 302, a gland 303 and a transparent plate 301. The frame body 302 is provided with a window, and a clamping groove is provided at the bottom side of the window.
