Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 2 、 Figure 4, the utility model provides an embodiment: a filter quick-release installation structure for a welding mask, comprising a cover body 1, the cover body 1 is a plate body for protecting the user's face and head of the welding mask, through which the user can be better protected, the front surface of the cover body 1 is fixedly connected to a frame 2, the frame 2 is a sealing frame for installing the filter set at the front end of the welding mask to ensure the stability of the filter installation, the inner wall of the front end of the frame 2 is provided with a sealing groove 5, the inner wall of the front top of the frame 2 is provided with a limiting groove 6, the limiting groove 6 is the limit point for the filter 44 to be installed on the inner wall of the frame 2, the outer wall of the front end of the frame 2 is provided with a protective mechanism, and the inner wall of the front end of the frame 2 is provided with a A disassembly and assembly mechanism is provided, which includes a limit component 41, a positioning component, and a light-transmitting component. The positioning component includes a rectangular plate 42 that ensures that the positioning block 43 can move horizontally stably back and forth. The rectangular plate 42 is slidably connected to the inner wall of the front end of the frame 2. The lower surface of the front end of the rectangular plate 42 is fixedly connected with the positioning block 43. The positioning block 43 is set in a concave shape, and the filter 44 can be stuck in it to ensure the stability of the filter 44 front and back. The light-transmitting component includes a filter 44. The filter 44 is a prior art. It is a filter that can filter the welding light and protect the user's eyes. The filter 44 slides on the inner wall of the positioning block 43.

[0032] Reference Figure 1 - Figure 2 、 Figure 5 The protective mechanism includes a protective cover 31 for protecting the filter 44. A notch is provided in the middle of the top and bottom of the protective cover 31, and the notch fits in the rectangular shell 411 to ensure the stability of the installation of the protective cover 31. The inner wall of the protective cover 31 contacts the outer wall of the front end of the frame 2. The rear surface of the right end of the protective cover 31 is fixedly connected to a rectangular bar 33 that ensures the stable front and rear horizontal movement of the protective cover 31. The outer wall of the rectangular bar 33 is slidably connected to a rotating rod 32. The rectangular bar 33 can only slide horizontally back and forth on the inner wall of the rotating rod 32 to ensure that it can smoothly drive the rotating rod 32 to rotate when it rotates. The rotating rod 32 is rotatably connected to the right side of the front surface of the cover body 1 near the frame 2. The rear surface of the rectangular bar 33 is fixedly connected to a spring 1 34. The spring 1 34 always pulls the rectangular bar 33 in sequence through its own elasticity to ensure the sealing effect of the protective cover 31. The rear end of the spring 1 34 is fixedly connected to the inner wall of the rotating rod 32.

[0033] Reference Figure 2 - Figure 4 The light-transmitting component also includes a sealing strip 45 to ensure the sealing of the filter 44 installed on the inner wall of the frame 2. The right surface of the sealing strip 45 contacts the inner wall of the sealing groove 5. The limiting component 41 includes a rectangular shell 411. The rectangular shell 411 is adapted to the inner wall of the top front end of the frame 2 to ensure the sealing of the filter 44. The rectangular shell 411 is fixedly connected to the upper surface of the front end of the rectangular plate 42, and the rectangular shell 411 contacts the inner wall of the top front end of the frame 2.

[0034] Reference Figure 2 - Figure 3 The limiting assembly 41 also includes a limiting block 413 for limiting the rectangular plate 42. The limiting block 413 is connected to the bottom end of the right surface of the rectangular shell 411 through sliding. The right surface of the limiting block 413 contacts the inner wall of the limiting groove 6. The inner wall of the rectangular shell 411 is elastically connected to the push plate 412 through the spring 2 414. The spring 2 414 always pushes the push plate 412 to move upward through its own elasticity to ensure the stability of the limiting block 413. The push plate 412 is connected to the front of the upper surface of the rectangular shell 411 through sliding. The second end 414 of the spring is fixedly connected to the inner wall of the rectangular shell 411, and the other end of the spring 414 is fixedly connected to the lower surface of the push plate 412. The left surface of the limit block 413 is fixedly connected to the slide bar 415. The front surface of the push plate 412 is provided with a through slot 416. The through slot 416 itself has a certain slope to ensure that when the push plate 412 is pushed, the slide bar 415 can move to the left or right along the slope of the through slot 416. The outer wall of the left end of the slide bar 415 is slidably connected to the inner wall of the through slot 416.

[0035] Working principle: When the filter 44 needs to be disassembled during use, the push plate 412 can be pushed, and the push plate 412 will squeeze the spring 2 414. At this time, the slide bar 415 will slide on the inner wall of the through groove 416 and follow the slope of the through groove 416 to drive the limit block 413 to move, so that the limit block 413 is separated from the inner wall of the limit groove 6. At this time, the rectangular plate 42 can be pulled through the rectangular shell 411, and the rectangular plate 42 will drive the positioning block 43 and the filter 44 to move out of the inner wall of the frame 2. The moved rectangular plate 42 can be taken out by pulling it from the left or right side of the positioning block 43. When the filter 44 is moved out, the sealing strip 45 will be separated from the inner wall of the sealing groove 5 by its own elasticity. When installing, insert the filter 44 into the inner wall of the positioning block 43. The subsequent operations are the same as above, but the direction of movement of some structures is opposite to that of the above.

[0036] When the welding helmet is not in use, the filter 44 can be protected by covering the front side of the frame 2 with the protective cover 31. You only need to pull the protective cover 31, and the protective cover 31 will drive the rectangular bar 33 to move and stretch the spring 1 34. Then rotate the protective cover 31 so that it drives the rotating rod 32 to rotate while the protective cover itself rotates with the center of the rotating rod 32 as the origin until the protective cover 31 coincides with the front side of the frame 2. At this time, you can loosen the protective cover 31 and make it stuck on the front side of the frame 2. In this way, the filter 44 can be protected to avoid damage to the filter 44, thereby improving practicality. When it needs to be opened, the operation is the same as above. The protective cover 31 can be rotated to one side of the frame 2 to prevent it from automatically closing and affecting the user's operation.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
