[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-4 The present invention provides an embodiment of a convenient and detachable headphone cover structure, including a head clip 1, the head clip 1 having an internal slot 2 to provide sufficient space to accommodate other components, a limiting post 3 fixedly connected to one side of the head clip 1, the main function of which is to cooperate with the limiting hole 5 in the steel headband 4 to prevent other components from shifting or slipping, a steel headband 4 provided on one side of the head clip 1, the steel headband 4 having a limiting hole 5 inside, a sliding groove 6 inside the steel headband 4, the limiting post 3 slidably connected inside the limiting hole 5, and a connecting component provided on one side of the steel headband 4;

[0030] The connecting assembly includes a wire ring 7, which is located on one side of the steel bar headband 4. The function of the wire ring 7 is to connect the steel bar headband 4 to other components. The wire ring 7 is in contact with the steel bar headband 4. A head clamp cover 8 is provided on the outer wall of the wire ring 7. A limit groove 9 is formed inside the head clamp cover 8. A fixing assembly is provided on one side of the head clamp cover 8. The fixing assembly includes a fixing plate 11, which is located on one side of the head clamp cover 8 and fits against the head clamp cover 8. A positioning post 10 is fixedly connected to one side of the head clamp cover 8. A positioning hole 12 is formed inside the fixing plate 11, and the positioning post 10 is slidably connected inside the positioning hole 12. The internal sliding connection of the 11 is a pin 13, which is slidably connected inside the limiting groove 9 and the sliding groove 6. The outer wall of the pin 13 is fixedly connected to a beveled block 14. The pin 13 slides in the sliding groove 6 and cooperates with the limiting groove 9 in the head clamp cover 8. The design of the pin 13 has both sliding and locking properties, which can facilitate disassembly and installation. The beveled block 14 is fixedly connected to the outer wall of the pin 13. The presence of the beveled block 14 can provide an additional locking function during the sliding of the pin 13 to prevent the pin 13 from loosening during use. The beveled block 14 is in contact with the wire ring 7.

[0031] Specifically, when assembling the headphone cover, initial positioning is required first. The limiting post 3 of the head clip 1 is inserted into the limiting hole 5 of the steel headband 4. This operation ensures the initial fixation of the head clip 1. Next, the wire ring 7 needs to be fitted with the head clip cover 8. The wire ring 7 plays an important role in supporting and fixing the ear pads in the headphone cover. By cutting, the stress of the wire is changed, allowing for better deformation. Subsequently, the positioning post 10 of the head clip cover 8 is inserted into the positioning hole 12 of the fixing plate 11 to ensure precise alignment between the head clip cover 8 and the fixing plate 11. After completing the docking of the head clip cover 8 and the fixing plate 11, the next step is to connect the pin 13 with other components. At this point, the outer wall of the pin 13 has a beveled block 14, which is designed with a special beveled shape to allow the pin 13 to be smoothly inserted into the square hole inside the fixing piece 11. When the pin 13 is inserted, the beveled angle of the beveled block 14 is 50 degrees, which can easily be inserted between the wire rings 7 to lock and fix it. After the pin 13 successfully passes through the limiting groove 9 and the sliding groove 6, it interacts with the wire rings 7 to form a solid fixing structure, thus completing the final fixing of the headphone cover. When disassembling, due to the tight fit between the pin 13 and other components, a large force is usually required to pull out the pin 13 in the direction of pull-out. This design allows the headphone cover to be firmly fixed, but it will not loosen on its own during normal use. During disassembly, by pulling out the pin 13, the angle of the beveled block 14 is 25 degrees, which can disengage the wire ring 7 and the head clip cover 8 from their original positions, making it easier to replace the ear tips or perform maintenance operations. Users only need to apply appropriate force during disassembly to easily remove the ear tips, realizing the convenient disassembly and installation function of the ear tips.

[0032] Working principle: When assembling the earphone cover, firstly, the limiting post 3 of the head clip 1 is inserted into the limiting hole 5 of the steel headband 4 for initial positioning. Next, the steel wire ring 7 is engaged with the head clip cover 8, and then the positioning post 10 of the head clip cover 8 is inserted into the positioning hole 12 of the fixing plate 11 for precise alignment. Finally, the beveled block 14 on the outer wall of the pin 13 is inserted into the square hole inside the fixing plate 11, so that it passes through the limiting groove 9 and the sliding groove 6 and interacts with the steel wire ring 7 to complete the fixation. When disassembling, a large force needs to be applied to pull it out along the direction of the pin 13 to remove the earphone cover. This realizes the function of convenient disassembly and installation of the earphone cover, which makes it easy to replace the ear tips, improves the user experience, and also facilitates production operations and improves production efficiency.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
