[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] Reference Figures 1-3 This utility model discloses a perforated earring, including a main body and a perforated part. The main body includes a gold body 1 (made of K gold), and a groove 2 is provided on one side of the gold body 1. The perforated part includes a titanium needle 3 (made of titanium metal), and a base support 4 is provided at one end of the titanium needle 3. An electroplated layer 8 is provided on the base support 4, and the base support 4 is welded to the groove 2.
[0024] It is understandable that in this embodiment, the titanium needle 3 is welded to the accessory of the gold body 1. The use of titanium metal for the piercing part can solve the problems of "sores" and "suppuration" caused by pierced earrings for allergy sufferers, thus meeting the needs of allergy sufferers for pierced earrings.
[0025] In some embodiments, the electroplating layer 8 is a gold plating layer. Because titanium and gold exhibit a repulsive reaction during the welding process, the titanium does not absorb the welding flux and cannot adhere to its surface, thus preventing a stable weld connection. Therefore, by first plating a gold layer on the base plate 4 of the titanium needle 3, a stable weld connection can be achieved between the titanium needle 3 and the gold body 1.
[0026] In a preferred embodiment, the electroplated layer 8 includes a silver plating layer and a gold plating layer. Compared with using only a gold plating layer, this reduces costs and allows the electroplated gold plating layer to better adhere to the solder flux, thereby improving the welding effect.
[0027] The electroplating process is as follows: Copper oil is applied to the base plate 4 of the titanium needle 3. The titanium needle 3 is then inserted into a rubber sleeve, leaving the copper-oil-coated base plate 4 exposed. Copper oil is a conductive liquid containing copper ions, which promotes the deposition of metal ions during electroplating. A fine brush is used to apply an appropriate amount of copper oil evenly to the surface of the titanium metal base plate 4, ensuring that the surface of the base plate 4 is completely covered with copper oil. After application, the titanium needle 3 is carefully inserted into the rubber sleeve. The inner diameter of the rubber sleeve is slightly larger than the diameter of the titanium needle 3, allowing it to tightly enclose the titanium needle 3, leaving only the base plate 4 exposed. The function of the rubber sleeve is to protect the titanium needle 3 from corrosion by the electroplating solution during the electroplating process, while ensuring that only the base plate 4 is electroplated.
[0028] Then, the titanium needle 3, fitted with a rubber sleeve, is placed in the electroplating tank. First, silver plating is performed on the base tray 4, followed by gold plating, resulting in a gold layer deposited on the copper-coated base tray 4. During the silver plating process, the electroplating tank volume is 200 liters, and the electroplating solution temperature is controlled between 28℃ and 30℃, specifically 29℃. The titanium needle 3 with the rubber sleeve is connected to the cathode of the electroplating equipment, and the silver anode is connected to the anode, with the current set to 0.5-1.5 A / dm³. 2 The silver plating time is 10 minutes. After silver plating, remove titanium needle 3 and rinse it clean with water. During the gold plating process, transfer the silver-plated titanium needle 3 to a 150-liter gold plating tank. The temperature of the plating solution is controlled between 30℃ and 35℃, specifically 32℃. Connect titanium needle 3 to the cathode of the electroplating equipment and the gold anode to the anode of the electroplating equipment, setting the current density to 0.1-0.5 A / dm³. 2 The gold plating time is 15-20 seconds, specifically 18 seconds. After the gold plating is completed, remove the titanium needle 3, rinse it with clean water, and then dry it with hot air.
[0029] The welding process is as follows: Remove the rubber sleeve to obtain the titanium needle 3 with the gold-plated base plate 4. Carefully remove the rubber sleeve from the titanium needle 3 to avoid damaging the gold plating on the base plate 4. Preheat the base plate 4 with the gold plating on the titanium needle 3. After preheating, the temperature of the base plate 4 is 300-500 degrees. Immediately after preheating, borax and low-temperature solder adhere to the base plate 4 and insert it into the groove 2 of the gold body 1. Then heat the groove 2 area. After the low-temperature solder melts, stop heating. After the melted low-temperature solder and the melted part on the gold body 1 and the gold plating layer cool down, a welding layer 9 is formed, which connects the gold body 1 and the titanium needle 3 into one piece to obtain the pierced earring.
[0030] In this embodiment, the thickness of the electroplated layer 8 is 5-8 μm, preferably 8 μm. When the electroplated layer 8 includes a silver plating layer and a gold plating layer, the thickness of the silver plating layer is 3 μm and the thickness of the gold plating layer is 5 μm. The diameter of the titanium needle 3 is 0.7-0.9 mm, preferably 0.8 mm, and the length of the titanium needle 3 is 7-9 mm, preferably 8 mm. The diameter of the base support 4 is 1.1-1.3 mm, preferably 1.2 mm, and the thickness of the base support 4 is 0.35-0.45 mm, preferably 0.4 mm. The depth of the groove 2 is 0.75-0.85 mm, preferably 0.8 mm, and the diameter of the groove 2 is 1.2-1.4 mm. The diameter of the groove 2 is always 0.1 mm greater than the diameter of the base support 4. When the diameter of the base support 4 is preferably 1.2 mm, the diameter of the groove 2 is 1.3 mm.
[0031] By setting various sizes, we can obtain pierced earrings that are aesthetically pleasing, highly practical, and structurally stable.
[0032] In a preferred embodiment, refer to Figure 2-3 A setting groove 7 is provided on the side of the gold body 1 away from the groove 2. A decorative part 6 is provided in the setting groove 7. Specifically, the decorative part 6 is fixed in the setting groove 7 by small claws or interference fit. The decorative part 6 includes gemstones, pearls or jade, which can give the pierced earrings different styles and characteristics to meet the aesthetic needs of different consumers.
[0033] In a preferred embodiment, refer to Figure 1-3 The titanium needle 3 has a connecting part 5 at the end away from the base support 4. The connecting part 5 includes an annular groove 2 on the titanium needle 3, and a cap (not shown in the figure) is connected to the connecting part 5. This allows the cap to be put on after wearing pierced earrings to prevent them from falling off.
[0034] 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.
