Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] Refer to Figure 1 - Figure 5, An embodiment provided by the present utility model: A dust-proof safety helmet, which includes a safety helmet top 1. An outer wall of the safety helmet top 1 is fixedly connected with a visible dust-proof mirror 2. An outer wall of the visible dust-proof mirror 2 is fixedly connected with a strap 5. An outer wall of the visible dust-proof mirror 2 is rotatably connected with a protective face mask 3. An upper surface of the protective face mask 3 is fixedly connected with a buckle 6. The buckle 6 facilitates the connection between the protective face mask 3 and the visible dust-proof mirror 2. Then, the safety helmet is fixed through the strap 5. Finally, air is filtered through a filter plate 4 to achieve dust prevention. The filter plate 4 is slidably connected inside the protective face mask 3. One side of an outer wall of the filter plate 4 is fixedly connected with a fixing plate 7. A handle 8 is slidably connected to an outer wall of the fixing plate 7. By pulling the handle 8, the fixing plate 7 and the filter plate 4 can be driven to move inside the protective face mask 3. A pull-back assembly 9 is arranged inside the handle 8. The pull-back assembly 9 is used to pull the handle 8 back. A push block 10 is fixedly connected to an outer wall of the handle 8. A latch 11 is slidably connected inside the fixing plate 7. By the movement of the handle 8, the push block 10 is driven to move inside the fixing plate 7, so that the inclined surface of the push block 10 presses on the latch 11, causing the latch 11 to slide inside the protective face mask 3 and the fixing plate 7. A first telescopic rod 13 is fixedly connected inside the latch 11. A second telescopic spring 12 is sleeved on an outer wall of the first telescopic rod 13. One end of the second telescopic spring 12 is fixedly connected inside the latch 11, and the other end of the second telescopic spring 12 is fixedly connected inside the fixing plate 7. By the movement of the latch 11, the second telescopic spring 12 is pressed, so that the second telescopic spring 12 expands and contracts between the latch 11 and the fixing plate 7. At the same time, the movement of the second telescopic spring 12 is guided by the first telescopic rod 13 to prevent the second telescopic spring 12 from being damaged. The pull-back assembly 9 includes a slide bar 901. One end of the slide bar 901 is fixedly connected inside the handle 8. A first telescopic spring 902 is sleeved on an outer wall of the slide bar 901. One end of the first telescopic spring 902 is fixedly connected inside the handle 8, and the other end of the first telescopic spring 902 is fixedly connected inside the fixing plate 7. By pulling the handle 8, the slide bar 901 will be driven to slide inside the fixing plate 7, and at the same time, the first telescopic spring 902 will be stretched. When the handle 8 is released, the first telescopic spring 902 is no longer stressed and rebounds, driving the handle 8 back to its original position for convenient use next time. In this process, the slide bar 901 guides the first telescopic spring 902 to prevent the first telescopic spring 902 from being damaged.
[0029] Refer to Figure 6 - Figure 8, a lining 14 is slidably connected inside the safety helmet top 1. A buffer ring 15 is fixedly connected to the outer wall of the lining 14. The buffer ring 15 is fitted with the safety helmet top 1. The buffer ring 15 is arranged between the safety helmet top 1 and the lining 14 to buffer external forces. A fixed seat 16 is fixedly connected inside the safety helmet top 1. A first rotating seat 17 is rotatably connected inside the fixed seat 16. A second telescopic rod 18 is fixedly connected to the outer wall of the first rotating seat 17. A buffer spring 19 is sleeved on the outer wall of the second telescopic rod 18. One end of the buffer spring 19 is fixedly connected to the outer wall of the first rotating seat 17. The other end of the buffer spring 19 is fixedly connected to a second rotating seat 20. The outer wall of the second rotating seat 20 is rotatably connected inside the lining 14. When the safety helmet top 1 is affected by external forces, it will slide on the outer wall of the lining 14, thereby driving the fixed seat 16 and the first rotating seat 17 to move. At this time, the movement of the first rotating seat 17 causes the second telescopic rod 18 and the buffer spring 19 to expand and contract between the second rotating seat 20 and the first rotating seat 17, thereby buffering external forces. A reinforcing rib 21 is fixedly connected inside the lining 14 to improve the strength of the lining 14 through the reinforcing rib 21. A buffer pad 22 is fixedly connected to the inner wall of the lining 14 to further buffer and protect the worker's head through the buffer pad 22. An air permeable component 23 is arranged inside the safety helmet top 1. The air permeable component 23 is used for ventilating the inside of the safety helmet top 1. The air permeable component 23 includes air permeation holes 2301. The air permeation holes 2301 are opened inside the safety helmet top 1 and inside the lining 14. A filter screen 2302 is fixedly connected inside the safety helmet top 1. By opening the air permeation holes 2301 inside the safety helmet top 1 and the lining 14, ventilation is facilitated. In addition, the filter screen 2302 filters dust in the air to prevent the dust from affecting the worker. The outer wall of the buckle 6 is slidably connected inside the visible dust-proof mirror 2. The buckle 6 is used for fixing the protective face mask 3. The outer wall of the push block 10 is slidably connected inside the fixed plate 7. The push block 10 is used for pressing the block 11. The outer wall of the block 11 is slidably connected inside the protective face mask 3. The block 11 is used for fixing the fixed plate 7. One end of the second telescopic rod 18 is fixedly connected to the outer wall of the second rotating seat 20. The second telescopic rod 18 is used for guiding the buffer spring 19;
[0030] Working principle: When the dust-proof safety helmet is needed, first, the staff wears the safety helmet and fixes it through the strap 5. Then, the protective mask 3 is pulled, so that the protective mask 3 fits with the visible dust-proof mirror 2. During this process, the buckle 6 at the top of the protective mask 3 will move into the interior of the visible dust-proof mirror 2, thus realizing the fixation of the protective mask 3. When in use, the eyes of the staff are protected through the visible dust-proof mirror 2. In addition, the air is dust-removed and filtered through the filter plate 4 inside the protective mask 3. After long-term use, the handle 8 can be pulled, so as to drive the telescopic spring one 902 to stretch. At the same time, the push block 10 slides inside the fixed plate 7. The inclined surface of the push block 10 presses on the clamping block 11, so that the clamping block 11 slides inside the fixed plate 7 and the interior of the protective mask 3. At the same time, the telescopic spring two 12 contracts through the sliding of the clamping block 11. When the clamping block 11 completely moves into the interior of the fixed plate 7, the filter plate 4 can be pulled out of the interior of the protective mask 3 for cleaning. During installation, only need to place the filter plate 4 back to the original position correspondingly, and then release the handle 8. At this time, the clamping block 11 is pushed by the rebound of the telescopic spring two 12 to move back into the interior of the protective mask 3, realizing disassembly and assembly to maintain the dust-removing effect;
[0031] In addition, when an external force impacts the safety helmet top 1, it will drive the fixed seat 16 to move downward. At this time, the rotation seat one 17 moves downward through the movement of the fixed seat 16, so that the telescopic rod two 18 expands and contracts between the rotation seat two 20 and the rotation seat one 17, thereby buffering the external force. At the same time, when the external force is large, the safety helmet top 1 will be pressed down excessively, so that the safety helmet top 1 presses on the buffer ring 15. Then, the buffer ring 15 cooperates with the buffer pad 22 on the inner wall of the inner lining 14 to further buffer. In addition, the overall strength of the inner lining 14 can be strengthened through the reinforcing rib 21 to achieve the protection effect. Finally, ventilation is realized through the ventilation holes 2301 preset inside the safety helmet top 1 and the inner lining 14. At the same time, the dust in the air is filtered through the filter screen 2302, thereby improving the wearing comfort.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
