[0003] However, when replacing the traditional cotton sleeve, the cotton sleeve is removed from the audio head by brute force. The traditional cotton sleeve is fixed to the edge of the audio head by multiple clip-on connections. Therefore, more force is required to remove the cotton sleeve, and the clips need to be pressed and fixed one by one during installation. The operation and fixing are cumbersome and the efficiency of replacing the cotton sleeve is low. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0022] See also Figure 1-6 The utility model provides a technical solution: an earphone cotton cover fixing mechanism, including a connecting seat 1, an audio head 3 is fixed on the inner side of the connecting seat 1, a headband 2 is fixedly connected to the upper ends of the two connecting seats 1, a cotton cover 4 is provided on the inner end of the audio head 3, a fixed ring 5 is fixedly connected to the lower end of the outer edge of the audio head 3, a movable ring 8 is provided on the upper end of the fixed ring 5, a card slot 6 is opened on the inner side walls of the fixed ring 5 and the movable ring 8, a card slot 6 is opened on the inner side walls of the fixed ring 5 and the movable ring 8, a card ring 10 is fixedly connected to the edge of the cotton cover 4 near the audio head 3, the card ring 10 is matched with the card slot 6, and the movable ring 8 is fixed with the card slot 6. The two ends of the fixed ring 5 are matched with the fixed connection setting; when replacing the cotton cover 4, the movable ring 8 is separated from the fixed ring 5 toward the upper end. After the movable ring 8 is removed upward, the clamping ring 10 of the cotton cover 4 can be slid vertically upward from the slot 6 of the fixed ring 5, and then the clamping ring 10 of the new cotton cover 4 is vertically inserted into the slot 6 of the fixed ring 5, and the movable ring 8 is inserted from the upper end of the clamping ring 10. Similarly, the slot 6 is clamped with the upper end of the clamping ring 10, and the cotton cover 4 can be replaced. This replacement method is not only simple to install but also efficient.

[0023] like Figure 6 As shown, fixed through-holes 12 are provided on the upper sides of both ends of the fixed ring 5, and fixed clamps 13 are fixedly connected to the lower sides of both ends of the movable ring 8. The fixed through-hole 12 is L-shaped, and the lower end passes through the fixed ring 5. The fixed clamp 13 is L-shaped, and the lower end is matched with the folded position of the fixed through-hole 12 for clamping; the lower ends of both ends of the movable ring 8 are fixedly connected with fixed clamps 13, which are inserted from the upper end of the fixed through-hole 12. After insertion, continuously pressing the movable ring 8 downward can press the end of the fixed clamp 13 to the bend of the fixed through-hole 12 for restricting and fixing. The clamping method can achieve stable connection and is easy to operate. When disassembling, push the fixed clamp 13 inward to remove the movable ring 8 upward.

[0024] like Figure 5 As shown, the upper and lower vertical ends of the fixed ring 5 and the movable ring 8 are provided with limiting perforations 9, and the upper and lower ends of the clamping ring 10 are fixedly connected to the limiting blocks 11, and the limiting blocks 11 are matched with the limiting perforations 9; the limiting perforations 9 can facilitate the fixation of the cotton sleeve 4, and the limiting blocks 11 at the upper and lower ends of the clamping ring 10 are inserted into the vertically opened limiting perforations 9, which not only facilitates installation, but also can fix the position of the cotton sleeve 4 so that it does not rotate during use.

[0025] like Figure 5 As shown, the inner wall of the card slot 6 is fixedly connected with a sealing ring 7, and the sealing ring 7 is matched with the protruding end of the clamping ring 10 and is set to abut against each other. When the two ends of the movable ring 8 and the fixed ring 5 are abutted, the sealing ring 7 on the inner side of the card slot 6 can abut against the protruding end of the clamping ring 10, and the sealing ring 7 is deformed by squeezing the sealing ring 7, so that the sealing ring 7 can achieve a sealing effect. Moreover, the sealing ring 7 can not only avoid vibration noise between the clamping ring 10 and the movable ring 8 and the fixed ring 5, but also achieve a better sealing effect and a better sound transmission effect.

[0026] like Figure 6 As shown, fixed blocks 14 are fixedly connected to both sides of the outer wall of the movable ring 8, and convex strips 15 are fixedly connected to the outer wall of the fixed block 14. The number of convex strips 15 is set in multiples and the spacing is equal. The fixed block 14 can facilitate the downward pressing of the movable ring 8. At the same time, the convex strips 15 on the outside of the fixed block 14 can facilitate the upward disassembly of the movable ring 8, thereby increasing the friction with the user's hand.

[0027] like Figure 6 As shown, elastic sheets 16 are fixedly connected to the upper ends of both sides of the outer wall of the fixed ring 5, and the lower end of the elastic sheet 16 is protruding and is located on the inner side of the fixed through-hole 12 to match the fixed clamp 13. When removing the movable ring 8, two fingers press the ends of the elastic sheets 16 on both sides at the same time, and squeeze the fixed clamp 13 inward through the protruding position of the end. The fixed clamp 13 moves inward to release the fixation of the movable ring 8, thereby making it more convenient to remove the movable ring 8.

[0028] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
