Detailed Description

In order to facilitate better understanding of the present invention for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, which are provided for illustration only and do not limit the scope of the present invention.

Fig. 1 and 2 show schematic structural diagrams of the present embodiment, which are schematic structural diagrams of the upper cover 20 being opened and closed by rotation, respectively, and include a body 10, the upper cover 20, and a connecting assembly 30. As shown in fig. 3, which is a schematic top structure view of the body 10, the top of the body 10 is provided with a fixing hole 11 and an arc-shaped rotation groove 12. Both ends of the rotary groove 12 are provided with limiting grooves 13, and the width of the limiting grooves 13 is larger than that of the middle section of the rotary groove 12. The distance from the center position of the rotary groove 12 to the center point of the fixed hole is the radius of the arc of the rotary groove.

Fig. 4 shows a schematic structural diagram of the upper cover of the present embodiment, and a convex fixing portion 21 and a convex rotating portion 22 are provided on an inner surface of the upper cover 20. The rotation part 22 is a middle broken cylindrical structure integrally connected with the upper cover 20. The rotary part 22 is made of elastic material and generates deformation tension when being pressed by itself. Preferably, the elastic material is a resin material.

Fig. 5 shows an installation diagram of the upper cover 20 and the body 10 of the present embodiment, in which the fixing portion 21 of the upper cover 20 is fitted into the fixing hole 11 of the body, and the rotating portion 22 of the upper cover 20 is fitted into the rotating recess 12. The upper cover 20 slides along the rotation groove 12 to be rotatably opened and closed. The rotation portion 22 slides along the rotation groove 12, and starts sliding from the stopper groove 13 from an initial closed state, and the rotation portion 22 is not deformed by being pressed. When the upper cover is opened, the rotating operation part 23 is operated to enable the rotating part 22 to slide into the middle section of the rotating groove 12, the rotating part 22 is squeezed, so that deformation tension is generated, the rotating part 22 continues to slide until the rotating part enters the limiting groove 13 at the other end of the rotating groove 12, the deformation tension received by the rotating part 22 is released, certain suction feeling is brought, and the upper cover is opened.

As shown in fig. 6, which is a cross-sectional view in the direction B-B of fig. 2. The fixing portion 21 of the upper cover 20 is provided with a screw hole corresponding to the drop-off preventing screw 31. As shown in fig. 7, which is a schematic view of the back structure of the body 10, the anti-falling screw 31 penetrates the first wear-resistant plate 32, then penetrates the back of the fixing hole 11 of the body 10, penetrates the second wear-resistant plate 33, and then penetrates the screw hole of the fixing portion 21 of the upper cover 20, so as to connect the upper cover 20 and the body 10.

In this embodiment, in order to replace the dry battery in the earphone, the dry battery holder 40 is exposed by rotating the upper cover of the earphone. The initial position of the upper cover 20 completely covers the top of the body 10. The rotating part 22 is located in the limiting groove 13 at one end of the rotating groove 12, and the anti-drop screw 31 and the wear-resistant sheet are used as a connecting component 30 to communicate the fixing part 21 and the fixing hole 11, so that the upper cover 20 and the body 10 are connected. The staff promotes rotatory operating portion 23, makes rotating portion 22 use fixed part 11 as the center along rotatory recess 12 and slides, when rotating portion 22 slides to the spacing groove 13 of the rotatory recess 12 other end, because the staff has felt the sense of inhaling, stop sliding, upper cover 20 rotates to the maximum position at skew body 10 top this moment, uncovers dry battery seat 40, after changing the dry battery, the staff promotes rotatory operating portion 23, make rotating portion 22 slide along curved rotatory recess 12 and return to the spacing groove 13 of rotatory recess 12 one end, until the staff feels the sense of inhaling, and the body 10 top has been covered completely.

The foregoing has described only the basic principles and preferred embodiments of the present invention and numerous changes and modifications may be made by those skilled in the art in light of the above teachings and shall fall within the scope of the present invention.
