Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Currently, with the improvement of living standards and the increasing purchasing power of people, jewelry and other decorative items are increasingly favored due to their decorative attributes and the diversity of their combinations. To meet users' personalized requirements for decorative items, a relatively movable display structure is often incorporated, allowing the structure to rotate or move relative to the main display part of the item, thereby enhancing its visual appeal. However, in related technologies, the display structure on the decorative item may experience uneven movement during operation, thus affecting the display effect.

[0024] Based on the above considerations, in order to solve the problem of poor display effect when the display structure on the decorative part moves in related technologies, a decorative part is designed. By setting the sliding part of the sliding structure in a groove opened on the display end face of the main structure, and making the sliding part slide in the groove, the sliding structure can move relative to the main structure to display according to the sliding of the sliding part in the groove, thereby improving the display effect. At the same time, an abutment part is provided on the side of the display part facing the display end face, and the surface of the abutment part is a convex arc surface. In this way, when the abutment part abuts against the display end face, the contact area between the abutment part and the display end face is effectively reduced, thereby effectively reducing the friction between the abutment part and the display end face, and thus effectively improving the smoothness of the overall movement of the sliding structure relative to the main structure, thereby improving the display effect of the decorative part.

[0025] The decorative parts provided in this application will now be further described with reference to specific embodiments.

[0026] Please refer to Figures 1 to 3This application provides a decorative component 100, including a main structure 10 and a sliding structure 20. Along the thickness direction h of the main structure 10, one side of the main structure 10 is a display end face 10a, and a groove 101 penetrating the main structure 10 is formed on the display end face 10a. The sliding structure 20 includes a display part 21, a sliding part 22, and a counterweight part 23 connected in sequence. The sliding part 22 is disposed within the groove 101 and slides in cooperation with the groove 101. The display part 21 is disposed on the display end face 10a. Above, the counterweight 23 is disposed on the side of the main structure 10 facing away from the display end face 10a; along the thickness direction h of the main structure 10, the projection of the display part 21 includes the projection of the sliding part 22, and the projection of the counterweight 23 includes the projection of the sliding part 22; wherein, the side of the display part 21 facing the display end face 10a is provided with an abutting part 21a, the abutting part 21a is arranged around the sliding part 22, the surface of the abutting part 21a is an outwardly convex arc surface, and part of the surface of the abutting part 21a abuts against the display end face 10a.

[0027] The main structure 10 and the sliding structure 20 refer to the two parts of the decorative element 100.

[0028] Optionally, the main structure 10 can be made of precious metals (gold, platinum, silver, etc.), agate, gemstones, etc.; or, the main structure 10 can be made of injection molded parts, plastics, alloy materials, etc. In some embodiments, diamonds, gemstones, agates, and other display materials can also be set on the main structure 10 to enhance the display effect of the main structure 10.

[0029] The sliding structure 20 can be made of precious metals (gold, platinum, silver, etc.), agate, gemstones, etc.; or, the sliding structure 20 can be made of injection molded parts, plastics, alloy materials, etc. In some embodiments, diamonds, gemstones, agate, and other display materials can also be set on the main sliding structure 20 to enhance the display effect of the sliding structure 20.

[0030] It should be understood that in this embodiment, the decorative element 100 may be, but is not limited to, a necklace, pendant, earring, bracelet, or other structure for wearing and display.

[0031] Along the thickness direction h of the main structure 10, one side of the main structure 10 is the display end face 10a; the display end face 10a refers to the side surface of the main structure 10 that is displayed outward when the decorative piece 100 is worn or used.

[0032] Along the thickness direction h of the main structure 10, a groove 101 penetrating the main structure 10 is provided on the display end face 10a; optionally, the groove 101 can be in various shapes such as strip, wave, arc, or ring. In this way, the sliding structure 20 can achieve movable display relative to the main structure 10 by sliding the sliding part 22 in the groove 101.

[0033] For example, in some embodiments, the main structure 10 may be rectangular or elongated, and the groove 101 may be a straight groove. In this way, the sliding structure 20 can achieve reciprocating linear sliding relative to the main structure 10 by sliding the sliding part 22 and the groove 101.

[0034] The sliding structure 20 includes a display part 21, a sliding part 22 and a counterweight part 23; wherein, the sliding part 22 is disposed in the slide groove 101 and slides in cooperation with the slide groove 101, so that the sliding part 22 can slide in the slide groove 101 and along the extension direction of the slide groove 101.

[0035] Optionally, the sliding part 22 can be a block-shaped structure, a cylindrical structure, etc.; the opposite end sidewalls of the sliding part 22 can slide against the inner wall of the groove 101 to enable the sliding part 22 to slide inside the groove 101. The display section 21 refers to the part of the main structure 10 located on one side of the display end face 10a and used for display purposes. Optionally, the display section 21 can be integrally formed with the sliding section 22; or, the display section 21 can be connected to the sliding section 22 by welding, screwing, snap-fitting, or other methods. The display section 21 can be, but is not limited to, a sphere, cylinder, prism, cone, frustum, or a combination of the above shapes.

[0036] The counterweight 23 refers to another structural part disposed on the side of the main structure 10 opposite to the display end face 10a. It is understood that the counterweight 23 serves to provide a counterweight, allowing the sliding part 22 to be more stably disposed in the slide groove 101 and to slide in cooperation with the slide groove 101. Optionally, the counterweight 23 can be integrally formed with the sliding part 22; or, the counterweight 23 can be connected to the sliding part 22 by welding, screwing, snap-fitting, or other methods. The counterweight 23 can be, but is not limited to, a sphere, cylinder, prism, cone, frustum, or a combination of the above shapes.

[0037] Along the thickness direction h of the main structure 10, the projection of the display part 21 includes the projection of the sliding part 22; thus, along the thickness direction h of the main structure 10, the projection area of ​​the display part 21 is larger, so that the display part 21 can be locked outside the slide groove 101, avoiding the situation where the display part 21 slides into the slide groove 101 and causes the sliding structure 20 to fall off.

[0038] Along the thickness direction h of the main structure 10, the projection of the counterweight 23 includes the projection of the sliding part 22; thus, along the thickness direction h of the main structure 10, the projection area of ​​the counterweight 23 is larger, so that the counterweight 23 can be locked outside the slide groove 101, preventing the counterweight 23 from sliding into the slide groove 101 and causing the sliding structure 20 to fall off.

[0039] The display section 21 has an abutment portion 21a on the side facing the display end face 10a. The abutment portion 21a refers to the part of the structure that abuts against the display end face 10a. The abutment portion 21a is arranged around the sliding section 22, so that the abutment portion 21a can replace the end face of the display section 21 and abut against the display end face 10a.

[0040] The surface of the abutting part 21a is a convex arc surface. In this way, when the abutting part 21a abuts against the display end face 10a, the contact area between the convex arc surface and the display end face 10a can be further reduced, thereby further reducing the contact area between the abutting part 21a and the display end face 10a.

[0041] It should be understood that if the display part 21 directly abuts against the display end face 10a, the contact area between the display part 21 and the display end face 10a is large. This means that during the sliding process of the sliding part 22, the friction between the display part 21 and the display end face 10a will hinder the sliding of the sliding part 22, thus affecting the sliding display effect of the sliding structure 20. By providing abutting part 21a with a convex arc surface on the side of the display part 21 facing the display end face 10a, and using abutting part 21a to replace the surface of the display part 21 and form contact with the display end face 10a, the contact area between the abutting part 21a and the display end face 10a can be effectively reduced, thereby reducing the friction between the abutting part 21a and the display end face 10a. This results in a smoother sliding effect of the sliding structure 20, effectively improving the sliding display effect of the sliding structure 20.

[0042] The decorative component 100 provided in this application embodiment improves the display effect by placing the sliding part 22 of the sliding structure 20 in a groove 101 opened on the display end face 10a of the main structure 10 and sliding the sliding part 22 in the groove 101. Simultaneously, an abutment part 21a is provided on the side of the display part 21 facing the display end face 10a, and the surface of the abutment part 21a is an outwardly convex arc surface. This effectively reduces the contact area between the abutment part 21a and the display end face 10a when they abut against each other, thereby reducing the friction between them and improving the smoothness of the overall movement of the sliding structure 20 relative to the main structure 10.

[0043] Please refer to Figures 1 to 3 In some embodiments, a protruding structure 11 is provided on the display end face 10a, and a groove 101 is formed on the surface of the protruding structure 11; a portion of the surface of the abutting portion 21a abuts against the surface of the protruding structure 11.

[0044] Understandably, the protruding structure 11 refers to the portion that protrudes from the display end face 10a. Optionally, the protruding structure 11 may be, but is not limited to, rectangular, circular, elliptical, or waist-shaped structures.

[0045] The groove 101 is formed on the surface of the protruding structure 11; thus, when the sliding part 22 of the sliding structure 20 is provided in the groove 101, the abutting part 21a provided on the surface of the display part 21 can abut against the surface of the protruding structure 11.

[0046] This design, by creating a groove 101 on the protruding structure 11 on the display end face 10a, allows the abutment portion 21a on the display part 21 to abut against the surface of the protruding structure 11. This increases the distance between the display part 21 and the display end face 10a, reducing the probability of them coming into contact. Simultaneously, it provides greater flexibility in the shape and construction of the display part 21, thus enhancing its diversity and consequently, the diversity of the decorative parts 100.

[0047] Please refer to Figures 1 to 3 In some embodiments, the main structure 10 has a receiving groove 12 on the side opposite to the display end face 10a, the sliding groove 101 is connected to the receiving groove 12, and the counterweight part 23 is disposed in the receiving groove 12.

[0048] In this embodiment, by opening a receiving groove 12 on the side of the main structure 10 facing away from the display end face 10a, when the sliding part 22 is slidably disposed in the sliding groove 101, the counterweight part 23 connected to the sliding part 22 will be located in the receiving groove 12.

[0049] It should be understood that along the thickness direction h of the main structure 10, when the projection of the counterweight 23 includes the projection of the sliding part 22, the projection of the receiving groove 12 that accommodates the counterweight 23 will also include the projection of the sliding groove 101, so that the counterweight 23 can slide synchronously with the sliding part 22.

[0050] This design, by placing the counterweight 23 within the receiving groove 12, prevents the counterweight 23 from extending beyond the main structure 10, thereby enhancing the comfort of the decorative piece 100 during wear and improving the overall display effect. Simultaneously, the inner wall of the receiving groove 12 provides a limiting effect on the counterweight 23, improving its smooth movement and thus enhancing the stability of the sliding structure 20 relative to the main structure 10, thereby improving the sliding display effect of the sliding structure 20.

[0051] Please refer to Figures 1 to 3 In some embodiments, the side surface of the counterweight 23 facing the sliding part 22 is an outwardly convex arc surface, and the side surface of the counterweight 23 facing the sliding part 22 abuts against the bottom wall of the receiving groove 12.

[0052] In this embodiment, the side surface of the counterweight 23 facing the sliding part 22 is configured as an outwardly convex arc surface, and the side surface of the counterweight 23 facing the sliding part 22 abuts against the bottom wall of the receiving groove 12. In this way, the contact area formed by the outwardly convex arc surface of the counterweight 23 abutting against the bottom wall of the receiving groove 12 is small. When the sliding part 22 slides in the sliding groove 101, the frictional force formed between the counterweight 23 and the bottom wall of the receiving groove 12 is small. This can effectively reduce the influence of the frictional force formed between the counterweight 23 and the bottom wall of the receiving groove 12 on the sliding of the sliding part 22.

[0053] Meanwhile, by abutting the counterweight 23 against the bottom wall of the receiving groove 12, and the abutting part 21a provided on the display part 21 against the display end face 10a, the stability of the sliding structure 20 on the main structure 10 can be further improved, so that when the sliding part 22 slides in the sliding groove 101, the overall stability of the sliding structure 20 is better, thereby effectively improving the sliding display effect of the sliding structure 20.

[0054] Please refer to Figures 1 to 3 In some embodiments, the protrusion structure 11 is disposed in the middle of the display end face 10a; a first display material 13 is also disposed on the display end face 10a, the first display material 13 is disposed at the outer edge of the display end face 10a, and the first display material 13 is arranged around the protrusion structure 11.

[0055] In this embodiment, the protruding structure 11 can be set in the middle of the display end face 10a. Thus, the first display material 13 can be set at the outer edge of the display end face 10a and the first display material 13 can be arranged around the protruding structure 11. As a result, the first display material 13 can be displayed in conjunction with the sliding structure 20 to effectively improve the overall display effect of the decorative part 100.

[0056] Among them, the first display material 13 mentioned above may be, but is not limited to, diamonds, gemstones, precious metals, agate and other materials with display value.

[0057] Please refer to Figures 1 to 3 In some embodiments, the display section 21 includes a display main section 211 and a second display material 212, the second display material 212 being disposed on the surface of the display main section 211.

[0058] The main display part 211 refers to the structural part used to connect with the sliding part 22. The second display material 212 is disposed on the surface of the main display part 211; optionally, the second display material 212 can be connected to the main display part 211 by means of inlay, bonding, snap-fit, etc.

[0059] The second display material 212 mentioned above may be, but is not limited to, diamonds, gemstones, precious metals, agate, and other materials with display value.

[0060] This configuration, by incorporating a second display material 212 into the main display section 211, further enhances the display effect of the display section 21. Furthermore, the sliding display effect of the display section 21 is improved when the sliding structure 20 moves relative to the main structure 10.

[0061] Please refer to Figures 1 to 3 In some embodiments, the projection of the sliding portion 22 is circular along the thickness direction h of the main structure 10.

[0062] In this embodiment, the projection of the sliding part 22 along the thickness direction h of the main structure 10 is set to a circle, that is, the sliding part 22 can be a cylindrical structure. Therefore, when the sliding part 22 is disposed in the slide groove 101 and slides in cooperation with the slide groove 101, the sliding part 22 can roll in the slide groove 101, that is, the sliding part 22 can reciprocate in the slide groove 101 in a rolling manner.

[0063] With this configuration, when the sliding part 22 rolls within the slide groove 101, the display part 21 can roll synchronously with the sliding part 22. This allows the display part 21 to rotate synchronously while moving relative to the main structure 10, thereby further enhancing the display effect of the display part 21.

[0064] Please refer to Figures 1 to 3 In some embodiments, the projection of the display section 21 along the thickness direction h of the main structure 10 is a polygon.

[0065] In this embodiment, the projection of the display part 21 along the thickness direction h of the main structure 10 is set as a polygon; optionally, the projection of the display part 21 can be, but is not limited to, any polygon such as a triangle, quadrilateral, pentagon, or hexagon.

[0066] With this configuration, as the display section 21 can roll synchronously with the sliding section 22, the polygonal display section 21 has a better display effect than the circular structure during the rolling process, and can better reflect the changing visual effect of rotation, thereby improving the display effect of the decorative part 100.

[0067] Please refer to Figures 1 to 3 In some embodiments, the weight of the display section 21 is the same as the weight of the counterweight section 23.

[0068] With this configuration, the weight of the display section 21 located at opposite ends of the sliding section 22 is the same as the weight of the counterweight section 23, and the stability of the sliding section 22 within the slide groove 101 is better, thereby further improving the smoothness of the movement of the sliding section 22 within the slide groove 101.

[0069] Please refer to Figures 1 to 3 In some embodiments, the dimensions of the inner sidewalls of the groove 101 are all the same along the thickness direction h of the main structure 10.

[0070] In this embodiment, by setting the dimensions of the inner sidewall of the slide groove 101 along the thickness direction h of the main structure 10 to be uniform, the stability of the sliding part 22, which is engaged in the slide groove 101 by the display part 21 and the counterweight part 23 at opposite ends, is better. This makes the movement of the sliding structure 20 relative to the main structure 10 more stable, thus improving the movement display effect of the sliding structure 20 and thereby improving the display effect of the decorative part 100.

[0071] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
