[0035] A cloth pad 5 is detachably connected to the outside of the cap band 4 (as shown in the appendix Figure 2 ), and the cap band 4 supports and fixes the position of the cloth pad 5. A plurality of cloth electrodes 11 are installed on the outside of the cloth pad 5 (as shown in the appendix Figure 3 ), and the cloth electrodes 11 are used to collect brain waves. A chip 12 is installed on the outside of the cloth pad 5, and the chip 12 is used to process the signals in the brain waves and process them, mainly to analyze the information of blood oxygen and pulse rate. A protective cover 6 is fixedly connected to the outside of the cap band 4 away from the cloth pad 5, and the cap band 4 supports and fixes the position of the protective cover 6. A rotating shaft 7 is rotatably connected to the inside of the protective cover 6, and the protective cover 6 supports and fixes the position of the rotating shaft 7. A round block 8 is fixedly connected to the outside of the rotating shaft 7. Manually rotating the round block 8 drives the rotating shaft 7 to rotate.
[0036] Four card cavities 13 are fixedly connected to the outside of the cap shell 1, and the cap shell 1 supports and fixes the positions of the four card cavities 13. A power component for supplying power to the structure is detachably connected inside the four card cavities 13. The power component includes a lining belt 16. The tops of the four lining belts 16 are fixedly connected to a cap lining 17, and the four lining belts 16 fix the position of the cap lining 17. The top of the cap lining 17 is fixedly connected to a fixing shell 18, and the cap lining 17 supports and fixes the position of the fixing shell 18. The top of the fixing shell 18 is fixedly connected to the inner wall of the cap shell 1, and the cap shell 1 supports and fixes the position of the fixing shell 18. A battery 19 is detachably connected inside the fixing shell 18 to supply power to the structures that need electricity in the safety helmet at any time.
[0037] Engaging blocks 15 are fixedly connected to the outside of the four lining belts 16 (as shown in the appendix Figure 3 ), and the lining belt 16 fixes the position of the engaging block 15. Blocks 14 are fixedly connected to the outside of the four engaging blocks 15, and the engaging block 15 supports and fixes the position of the block 14. The outside of the block 14 is detachably connected to the inner wall of the card cavity 13. The combined action of the block 14 and the card cavity 13 fixes the positions of the multiple lining belts 16. The other ends of the four engaging blocks 15 are fixedly connected to a chin strap 23 (as shown in the appendix Figure 4 ), and the four engaging blocks 15 fix the position of the chin strap 23.
[0038] Refer to Figure 5 . The other end of the rotating shaft 7 is fixedly connected to a gear 9 (as shown in the appendix Figure 5 ), and the rotation of the rotating shaft 7 drives the rotation of the gear 9. Two sliding openings are formed inside the cap hoop 4, and multiple teeth 10 are fixedly connected to the inner walls of the two sliding openings. The sliding openings fix the positions of the teeth 10. The outside of the multiple teeth 10 is meshed with the outside of the gear 9. The rotation of the gear 9 drives the multiple teeth 10 to move, causing the two sides of the cap hoop 4 to approach or move away from each other, enabling the cap hoop 4 to fit the human head more closely. Making the cap hoop 4 fit the head more closely can improve the stability and comfort of the safety helmet and reduce the risk of falling off during movement.
[0039] Refer to Figure 6, there are connecting blocks 24 fixedly connected to the outside of the two lower jaw straps 23. Each connecting block 24 can bring the two lower jaw straps 23 together and has a fixing effect on the position of the lower jaw straps 23. There is a fixing strap 25 fixedly connected to the outside of the connecting block 24, and the connecting block 24 has a fixing effect on the position of the fixing strap 25. There is a variable strap 26 fixedly connected to the outside of the other connecting block 24, and the other connecting block 24 has a fixing effect on the position of the variable strap 26. The other end of the fixing strap 25 is fixedly connected to a fastening block 27, and the fastening block 27 has a fixing effect on the position of the fixing strap 25. The other end of the fastening block 27 is fixedly connected to a chute box 28, and the fastening block 27 has a fixing effect on the position of the chute box 28. The variable chute box 28 can also change the position of the fastening block 27, and the change in the position of the fastening block 27 causes the position of the fixing strap 25 to change.
[0040] A pull plate 29 is slidably connected to the inner wall of the chute box 28 (as shown in the appendix Figure 6 ). The top of the pull plate 29 is fixedly connected to a fixing plate 31, and the pull plate 29 has a fixing effect on the position of the fixing plate 31. Two springs 33 are fixedly connected to the top of the fixing plate 31, and the fixing plate 31 has a fixing and supporting effect on the two springs 33. The other end of the fixing plate 31 is rotatably connected to an elastic plate 32. Pulling the pull plate 29 can drive the fixing plate 31 to move.
[0041] The other ends of the two springs 33 are fixedly connected to the bottom of the elastic plate 32. The movement of the fixing plate 31 drives the elastic plate 32 to move. The elastic plate 32 is first squeezed by the top of the chute box 28, causing the two springs 33 to deform and store elastic potential energy. As the pull plate 29 moves, the top of the chute box 28 no longer squeezes the top of the elastic plate 32, and the two springs 33 release the elastic potential energy, pushing the elastic plate 32 to move away from the fixing plate 31.
[0042] There is a tensioning block 30 fixedly connected to the outside of the pull plate 29. The other end of the variable strap 26 is slidably connected to the inside of the tensioning block 30. Pulling one corner of the variable strap 26 allows the tail of the variable strap 26 to pass more through the sliding hole of the tensioning block 30, adjusting the variable strap 26 so that its length better meets the needs of the user.
[0043] Referring to Figure 7 , a rotating shaft 20 is movably connected to the inside of the fixed shell 18, and the fixed shell 18 has a fixing effect on the position of the rotating shaft 20. One end of the rotating shaft 20 is fixedly connected to a rotating block 21 (as shown in the appendix Figure 7 ). Rotating the rotating block 21 drives the rotation of the rotating shaft 20. The other end of the rotating shaft 20 is fixedly connected to a rotating block 22, and the rotation of the rotating shaft 20 drives the rotation of the rotating block 22. A slideway is provided inside the fixed shell 18 (as shown in the appendix Figure 7), the outer part of the rotating block 22 is movably connected to the inner wall of the slide. When the rotating block 22 rotates to a certain position, the rotating block 21 is pulled, and the movement of the rotating block 21 drives the movement of the rotating shaft 20, and the movement of the rotating shaft 20 drives the movement of the rotating block 22, so that the rotating shaft 20 can drive the rotating block 22 to separate from the fixed shell 18, thereby allowing the battery 19 to be separated from the fixed shell 18, and realizing the removal and replacement of the battery 19.
[0044] Working principle: When it needs to be used, the safety helmet is placed on the operator's head, and the rotating block 8 drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the gear 9 to rotate. The gear 9 can make the multiple teeth 10 on both sides close to each other. The multiple teeth 10 are fixedly connected to the outside of the hat band 4, so the mutual approach of the multiple teeth 10 makes the two sides of the hat band 4 close to each other. The hat band 4 is made of tough material, so there is a certain deformation space, so that the hat band 4 can fit the human head more closely. Making the hat band 4 fit the head more closely can improve the stability and comfort of the safety helmet, reduce the risk of falling off during exercise, thereby enhancing the overall protection effect and the wearer's sense of security.
[0045] Finally, the other end of the pull plate 29 is inserted into the bottom inner wall of the slide box 28, so that after the spring plate 32 loses the pressing force of the slide box 28, it can be moved away from the fixed plate 31 due to the action of the spring 33. At this time, without the help of other external forces, pulling the pull plate 29 again will not change the position of the pull plate 29. This ensures that the safety helmet can better adapt to different head shapes and facial contours, and improves wearing comfort. Appropriate length adjustment allows the chin strap 23 to be firmly fixed under the wearer's chin, preventing the hat from sliding or falling off during activities, thereby ensuring the stability of the safety helmet. Adjusting the length of the chin strap 23 can effectively reduce the friction and pressure generated by the safety helmet during strenuous exercise or work, and improve the overall comfort of the wearer.
[0046] 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.
