[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0023] Please see Figure 1-3 A preferred embodiment of this utility model provides a threaded directional earring, including a first connector 1 and a second connector 2. The first connector 1 includes a decorative part 11 and a plug 12. One end of the plug 12 is connected to the decorative part 11, and the other end is provided with a threaded groove 121. The second connector 2 includes a stop part 21 and a connecting rod 22 with threads on its outer peripheral surface. The connecting rod 22 is used to be screwed into the threaded groove 121. By passing the plug 12 through the ear hole so that the decorative part 11 faces the face, and then inserting the connecting rod 22 into the threaded groove 121 and rotating the connecting rod 22, the connecting rod 22 is screwed into the threaded groove 121. The stop part 21 is located behind the ear, realizing the connection between the first connector 1 and the second connector 2, and the earring is securely worn on the ear.

[0024] Furthermore, a positioning block 122 is provided at the end of the insertion rod 12 away from the decorative part 11, and a positioning groove 211 is provided on the side of the stop part 21 facing the connecting rod 22. The positioning groove 211 is used to accommodate the positioning block 122 and restrict the rotation of the positioning block 122. Rotate the connecting rod 22 until the end of the connecting rod 22 near the stop part 21 is located in the thread groove 121 and the positioning block 122 is located in the positioning groove 211. The cooperation between the positioning groove 211 and the positioning block 122 can restrict the rotation of the connecting rod 22, ensuring that the stop part 21 and the decorative part 11 are positioned opposite each other when worn, preventing misalignment between the two, and also preventing the threads from loosening due to vibration, further ensuring the stability of the wearing.

[0025] Furthermore, the end of the connecting rod 22 away from the stop part 21 is tapered, and the cross-sectional area of ​​the end of the connecting rod 22 gradually decreases in the direction away from the stop part 21. This facilitates the insertion of the connecting rod 22 into the threaded groove 121 when connecting the first connecting member 1 and the second connecting member 2, making it convenient to use.

[0026] The stop part 21 is also provided with a connecting groove 212 on the side facing the connecting rod 22. The connecting rod 22 is welded into the connecting groove 212. During welding, the connecting rod 22 is placed in the connecting groove 212 first, which can facilitate the positioning of the welding position between the connecting rod 22 and the stop part 21, and facilitate subsequent manufacturing.

[0027] Furthermore, the connecting groove 212 is connected to the positioning groove 211. When machining the connecting groove 212 and the positioning groove 211 on the surface of the stop part 21, the two can be carved together, which helps to reduce the manufacturing difficulty.

[0028] In this embodiment, the depth of the connecting groove 212 is greater than the depth of the positioning groove 211, and the connecting rod 22 enters the connecting groove 212 more deeply, resulting in a larger contact area between the two, which facilitates their welding. Furthermore, the positioning block 122 is easier to remove from the positioning groove 211, so that the connecting rod 22 can be rotated in the opposite direction to separate the first connecting member 1 from the second connecting member 2.

[0029] Specifically, the thickness of the stop part 21 is 2-3 times the depth of the connecting groove 212, and the thickness of the stop part 21 is 4-5 times the depth of the positioning groove 211. If the connecting groove 212 and the positioning groove 211 are set too shallow, it will easily lead to the connecting rod 22 not being welded firmly and the positioning block 122 not being locked firmly. If they are set too deep, the stop part 21 will easily be punctured during processing, increasing the requirements for processing accuracy. Therefore, setting the depth of the connecting groove 212 and the depth of the positioning groove 211 within this range is a better implementation method.

[0030] In other embodiments, the depth of the connecting groove 212 can be set to be the same as the depth of the positioning groove 211, further reducing the manufacturing difficulty.

[0031] The positioning block 122 is integrally formed with the insertion rod 12. The positioning block 122 is cut from the end of the insertion rod 12, and the positioning block 122 is firmly connected to the insertion rod 12. Both the positioning block 122 and the positioning groove 211 are fan-shaped. The fan-shaped positioning block 122 is easy to cut from the end of the insertion rod 12, which is convenient to manufacture. Setting the positioning block 122 and the positioning groove 211 to be the same shape can ensure the snap-fit ​​effect.

[0032] The insert 12 is connected to the center of the decorative part 11, and the connecting rod 22 is connected to the center of the stop part 21. When wearing the earring, the ear hole is located at the center of the decorative part 11 and the stop part 21, which can better cover the ear hole and make it easier to use.

[0033] The surface of the decorative part 11 facing the insertion rod 12 and the surface of the stop part 21 facing the connecting rod 22 are both flat. When wearing the earring, the decorative part 11 and the stop part 21 can fit snugly on the ear, improving wearing comfort and making it easier to use.

[0034] The decorative part 11 and the stop part 21 are the same in shape and size. The earring can be worn on both sides. In actual use, the stop part 21 can face the face and the decorative part 11 can be located behind the ear. When wearing it, the user can see the position of the threaded groove 121 more clearly, so that the connecting rod 22 can be put into the threaded groove 121 for easy use.

[0035] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
