[0022] This specific embodiment is a knob-type opening wireless earphone charging case, the structural diagram of which is shown below. Figures 1-5 As shown, the device includes an earphone case 1, which has an internal slot 101 for placing earphones. A sealing cover 2 is rotatably mounted on the earphone case 1, and a rotating assembly 3 is provided between the earphone case 1 and the sealing cover 2. The principle and structure of charging the earphones placed in the slot 101 inside the earphone case 1 are existing technologies and will not be described in detail here.

[0023] The rotating assembly 3 includes bearings 301 fixedly installed at both ends of the headphone case 1 and spring pins 302 installed at both ends of the headphone case 1. Bearings 301 and spring pins 302 located on one side of bearings 301 are fixedly installed at both ends of the headphone case 1.

[0024] The rotating assembly 3 also includes an inner cover plate 303 fixedly installed at both ends of the sealing cover 2, a rotating shaft 304 fixedly installed on the inner wall of the inner cover plate 303, and a number of limiting holes 305 opened on the inner wall of the inner cover plate 303.

[0025] The rotating shafts 304 on the inner walls of the two inner cover plates 303 are respectively fixedly installed on the inner rings of the two bearings 301 at both ends of the earphone box 1. In this way, the rotating shafts 304 and the bearings 301 can not only support the sealing cover 2, but also allow the sealing cover 2 to rotate.

[0026] Several limiting holes 305 are arranged in a ring array on the inner wall of the inner cover plate 303. The cooperation between the spring pin 302 and the limiting hole 305 enables the sealing cover 2 to play a limiting role when it is not rotated, preventing the sealing cover 2 from rotating when it is not subjected to external force.

[0027] The sealing cover 2 has an outer cover plate 306 installed at its end for sealing the inner cover plate 303. In some embodiments, the inner cover plate 303 is integrally formed with the sealing cover 2, and the inner cover plate 303 has a slot. The outer cover plate 306 is fixedly installed with a buckle corresponding to the slot position. The outer cover plate 306 is fixed by placing the buckle inside the slot.

[0028] The spring pin 302 includes a fixed post 3021 fixedly installed at the end of the earphone case 1, a sliding post 3022 slidably installed with the fixed post 3021, and a spring 3023 installed inside the fixed post 3021;

[0029] In some embodiments, the interior of the fixed column 3021 is a hollow structure, and a limiting slider 3024 is fixedly installed at one end of the sliding column 3022. Two limiting sliders 3024 are provided, and the two limiting sliders 3024 are respectively fixedly installed on both sides of one end of the fixed column 3021. In this way, with the cooperation of the two limiting sliders 3024, the sliding column 3022 can be guided to slide, preventing the sliding column 3022 from tilting or deviating during the sliding process, and also preventing the sliding column 3022 from detaching from the fixed column 3021.

[0030] The other end of the sliding column 3022 is hemispherical, and the limiting hole 305 is an arc-shaped groove that matches the hemispherical shape of the other end of the sliding column 3022;

[0031] When the hemispherical extension of the other end of the sliding column 3022 is inserted into one of the limiting holes 305, the sealing cover 2 can be prevented from rotating when no external force is applied.

[0032] When the user rotates the sealing cover 2 by hand, the sealing cover 2 rotates through the cooperation of the rotating shafts 304 at both ends and the bearings 301 at both ends of the earphone case 1. During the rotation of the sealing cover 2, the arc-shaped groove of one of the limiting holes 305 compresses the hemispherical sliding post 3022, causing the sliding post 3022 to enter the interior of the fixed post 3021. During the rotation of the sealing cover 2, several limiting holes 305 will alternately compress the sliding post 3022. The compression of the sliding post 3022 will compress the spring 3023, putting the spring 3023 in a compressed state. When the sealing cover 2 is rotated to the open position, the placement groove 10 is exposed. When the sealing cover 2 is rotated to the position of the sealing placement groove 101, the sliding column 3022 corresponds to one of the limiting holes 305 among the several limiting holes 305. At this time, the sliding column 3022 and the spring 3023 are no longer squeezed. Under the action of the spring 3023, the sliding column 3022 can be pushed to move towards the limiting hole 305 until the other end of the sliding column 3022 enters the interior of the limiting hole 305. At this time, with the cooperation of the sliding column 3022 and the limiting hole 305, the sealing cover 2 is fixed to prevent the sealing cover 2 from rotating when it is not subjected to external force.

[0033] In other words, when the earphone is inserted: when the sealing cover 2 is rotated to the open position to expose the placement groove 101, the sealing cover 2 is fixed in position by the cooperation of the spring pin 302 and the limiting hole 305. In this way, the sealing cover 2 will not rotate during the process of inserting the earphone into the placement groove 101, so as not to affect the insertion of the earphone. After the earphone is inserted, the sealing cover 2 is rotated to the position of sealing the placement groove 101. At this time, the sealing cover 2 is fixed in position by the cooperation of the spring pin 302 and the limiting hole 305.

[0034] One end of the spring 3023 is fixed to the inner wall of the fixed post 3021, and the other end of the spring 3023 is fixed to one end of the sliding post 3022. When the sliding post 3022 is compressed, it will simultaneously compress the spring 3023, so that the spring 3023 is in a compressed state. When the sliding post 3022 is no longer compressed, under the action of the restoring force of the spring 3023, the sliding post 3022 is pushed to reset and enter the interior of the limiting hole 305.

[0035] One of the outer cover plates 306 has a lanyard hole for hanging a lanyard 4, which makes it convenient to carry the wireless earphone charging case.

[0036] In summary, when the sealing cover 2 is rotated to the open position to expose the placement slot 101, the sealing cover 2 is fixed in position by the cooperation of the spring pin 302 and the limiting hole 305. This prevents the sealing cover 2 from rotating during the placement of the earphones into the placement slot 101, thus not affecting the placement of the earphones. After the earphones are placed, the sealing cover 2 is rotated back to the position of sealing the placement slot 101. At this time, the sealing cover 2 is fixed in position by the cooperation of the spring pin 302 and the limiting hole 305, and the whole becomes cylindrical. The earphone case has a novel appearance design, which enhances the overall aesthetics of the product and makes it easy to carry.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
