[0031] like Figure 1 As shown, it is the waterproof headphone protective case 100 of this utility model, used to store headphones.
[0032] like Figures 1 to 2 As shown, the waterproof headphone protective case 100 includes: a main shell 10 and a cover 20, wherein the main shell 10 includes an annular wall 11 and a bottom cover 12, and the inner side of the annular wall 11 is provided with an internal thread 111, such as... Figure 3 As shown, the bottom cover 12 is connected to the annular wall 11 and together with the annular wall 11 forms an accommodating space 14. The cover 20 includes a cover body 21 and a sealing ring 22. The cover body 21 closes the accommodating space 14 and is connected to the external thread 213 with the internal thread 111. The sealing ring 22 is fitted onto the cover body 21 and makes a sealing contact with the annular wall 11 and the cover body 21. By using the internal thread 111 of the annular wall 11 of the main shell 10 to be threadedly connected to the external thread 213 of the cover body 21 of the cover 20, and by setting a sealing ring 22 for sealing contact between the annular wall 11 and the cover body 21, water can be effectively prevented from entering the accommodating space 14, thereby providing good waterproof protection for the headphones and achieving the purpose of improving the waterproof performance of the waterproof headphone protective shell 100.
[0033] The following text, combined with Figures 1 to 3 Further explanation is provided regarding the aforementioned waterproof headphone protective case 100.
[0034] like Figures 2 to 3As shown, the main shell 10 also includes a sealing ring 13, which is sealed to the ring wall 11 and the bottom cover 12. The sealing ring 13 can effectively enhance the waterproofness between the ring wall 11 and the bottom cover 12, preventing water from entering the receiving space 14 from the connection between the ring wall 11 and the bottom cover 12, thus providing reliable waterproof protection for the headphones.
[0035] Furthermore, such as Figures 1 to 2 As shown, the main shell 10 also includes a hanging ring 15, which is connected to the ring wall 11. The method of connecting the hanging ring 15 to the ring wall 11 facilitates carrying the ring wall 11 through the hanging ring 15, thereby improving the portability of the waterproof headphone protective shell 100.
[0036] Understandably, to improve the ease of use of the waterproof headphone case 100, the bottom cover 12 can be made of a transparent material. A transparent bottom cover 12 facilitates observation of the contents of the storage space 14, thereby improving the ease of use of the waterproof headphone case 100.
[0037] like Figure 2 As shown, the cover 21 includes a closing part 211 and a connecting part 212. The annular wall 11 is provided with a concealed groove 112 to accommodate the closing part 211. The connecting part 212 is provided with an external thread 213 and is sleeved with a sealing ring 22. The method of using the concealed groove 112 of the annular wall 11 to accommodate the closing part 211 of the cover 21 is beneficial to improving the integrity and aesthetics of the main shell 10 and the buckle 20 when connected.
[0038] Among them, such as Figure 2 As shown, the cover 211 is provided with a groove 218. The groove 218 is provided on the side of the cover 211 opposite to the connecting part 212. The groove 218 can be a straight groove or a cross groove. The groove 218 can effectively improve the rotation convenience of the cover 21, thereby improving the ease of use of the waterproof headphone protective shell 100.
[0039] Furthermore, such as Figures 1 to 2 As shown, the cover 211 is provided with a prompt mark 217. The prompt mark 217 is located on the side of the cover 211 opposite to the connecting part 212. The prompt mark 217 helps to indicate the rotation direction of the cover 21, so as to avoid the cover 21 being difficult to open or close due to incorrect rotation direction, thereby improving the ease of use of the cover 21.
[0040] like Figure 3 As shown, the connecting part 212 is provided with an annular groove 216, and the sealing ring 22 is fitted inside the annular groove 216 to prevent the sealing ring 22 from separating from the cover 21.
[0041] like Figures 1 to 2As shown, the cover 20 also includes a handle, which is connected to the cover body 21. The handle and the cover body 21 are rotatably connected. The cover body 21 is provided with a receiving groove 214 for receiving the handle and a clearance groove 215. The clearance groove 215 communicates with the receiving groove 214. By using a rotating handle to cooperate with the receiving groove 214 of the cover body 21, the handle can be used to increase the rotation convenience of the cover body 21 while effectively protecting the handle and ensuring the overall aesthetics of the waterproof headphone protective case 100, thereby improving the ease of use of the waterproof headphone protective case 100.
[0042] The waterproof headphone case 100 provided in this application is used as follows: Place the headphones into the receiving space 14 of the main shell 10, then align the external thread 213 of the cover 21 of the snap cover 20 with the internal thread 111 of the annular wall 11 of the main shell 10. Rotate the cover 21 to gradually tighten it onto the annular wall 11. During rotation, a seal is formed through the tight contact between the sealing ring 22, the annular wall 11, and the cover 21, thus achieving the connection between the main shell 10 and the snap cover 20. When it is necessary to remove the headphones, pry the handle out of the receiving groove 214 from the clearance groove 215, grasp the handle, and apply rotational force to easily open the snap cover 20, separating the main shell 10 and the snap cover 20. If the handle is not needed, it can also be rotated and stored in the receiving groove 214. When carrying the waterproof headphone case 100, it can be hung in a suitable position using the hanging ring 15 to achieve carrying of the waterproof headphone case 100.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
