[0032] Reference Figure 1 , this embodiment provides a chain ring 300. Specifically, the chain ring 300 can be formed by abutting and connecting two identical ring-forming parts. The ring-forming part may include a base, a cover body, a light source and a filling block. Among them, the base and the cover body can be matched and connected to form the outer shell of the ring-forming part, the light source can be arranged on the base and accommodated in the cavity formed after the base and the cover body are connected, and the cover body is at least partially made of a light-transmitting material, so that the light emitted by the light source in the cavity can pass through the outer shell of the ring-forming part from the light-transmitting part to achieve lighting.

[0033] In this embodiment, metal contacts may be provided on the ring-forming member, and power supply is achieved through the contact of the metal contacts on adjacent chain links 300 .

[0034] Specifically, taking the upper ring member 100 as an example, an upper shell metal contact 150 can be set on the inner side of the upper shell cover 110. When the chain light is installed, the upper ring members 100 of two adjacent chain links 300 are in contact on the inner side, so that the upper shell metal contacts 150 of the two upper ring members 100 are electrically connected to realize power supply. Similarly, a lower shell metal contact 250 can also be set on the inner side of the lower ring member 200.

[0035] In order to realize this metal contact electrical connection mode to realize power supply, after the chain light is installed, it is necessary to ensure that the upper ring-forming member 100 of the two adjacent chain links 300 is always in contact on the inner side. Therefore, the connecting parts on the ring-forming member can be used to cooperate with each other to clamp the adjacent chain links 300 in the locking structure so that the inner side surfaces of the adjacent chain links 300 are always in contact. For example, at least two connecting parts can be set on the upper ring-forming member 100, and the inner side surface of the ring-forming member and two of the connecting parts form a locking structure, and the inner side surface of the ring-forming member is provided with a metal contact at the position of the locking structure.

[0036] Specifically, as an embodiment, the base of the ring-forming member can be a ring-shaped structure, and a notch can be provided on the ring-shaped structure; at the same time, the shape of the cover body can be the same as that of the base, and the cover body is provided with an opening at a position corresponding to the notch. After the base is connected to the cover body, the notch on the base and the opening of the cover body together form an installation opening, and the ring-forming member of the adjacent chain link can be buckled into the ring-forming member from the installation opening of the ring-forming member. When the ring-forming member of the adjacent chain link is buckled in, a filling block can be detachably connected to the installation opening, thereby closing the installation opening to prevent the adjacent chain link from detaching from the chain link.

[0037] In order to facilitate the installation and fixation of the filling block, a limiting protrusion can be provided at the position of the opening of the cover body, and a groove matching the limiting protrusion can be provided on the filling block; or a limiting protrusion can be provided on the filling block, and a groove matching the limiting protrusion can be provided at the position of the opening of the cover body. When the filling block is detachably connected to the installation opening of the ring-forming member, the matching of the limiting protrusion and the groove can be used to position the filling block, and the filling block can be conveniently installed and fixed in the installation opening.

[0038] The filling block and the mounting opening can be directly snap-fitted, that is, the filling block and the mounting opening can be matched with each other, and the size of the filling block can be slightly larger than the mounting opening. When the filling block is inserted into the mounting opening, the filling block and the mounting opening are clamped together to form a snap-fit ​​similar to an interference fit.

[0039] More specifically, see Figure 1 and Figure 2 , the two identical ring-forming parts are an upper ring-forming part 100 and a lower ring-forming part 200. Among them, the upper ring-forming part 100 includes an upper shell cover 110, an upper shell light source 120, an upper shell base 130 and an upper shell filling block 140. The upper shell cover 110 and the upper shell base 130 are connected to form the shell of the upper ring-forming part 100, the upper shell light source 120 is accommodated in the cavity formed by the upper shell cover 110 and the upper shell base 130, and the upper shell filling block 140 is used to connect to the installation port of the upper ring-forming part 100 to close the installation port of the upper ring-forming part 100; the lower shell cover 210 and the lower shell base 230 are connected to form the shell of the upper ring-forming part 200, the lower shell light source is accommodated in the cavity formed by the lower shell cover 210 and the lower shell base 230, and the lower shell filling block 240 is used to connect to the installation port of the upper ring-forming part 200 to close the installation port of the upper ring-forming part 200.

[0040] In this embodiment, since the structures of the two loop-forming components constituting the same chain link 300 can be the same, when describing the structure of the loop-forming components, only the structure of the upper loop-forming component 100 is described as an example, and the structure of the lower loop-forming component 200 can refer to the upper loop-forming component 100.

[0041] Reference Figure 3In the upper ring member 100, the upper shell base 130 may be an annular structure, and a notch 134 is provided on the annular structure; the upper shell cover 110 may also be an annular structure, and has the same shape as the upper shell base 130, and the upper shell cover 110 may be provided with an opening 111 at a position corresponding to the notch 134. When the upper shell cover 110 is connected to the upper shell base 130, the notch 134 cooperates with the opening 111 to form an installation opening, and the upper shell filling block 140 is used to close the installation opening of the upper ring member 100.

[0042] Taking the upper ring member 100 as an example, the upper shell cover 110 can be provided with a limiting protrusion 112 at the opening, and a groove is provided on the upper shell filling block 140. When the upper shell filling block 140 is connected to the upper ring member 100, the mutual cooperation between the limiting protrusion 112 and the groove can be utilized to facilitate the positioning, installation and fixing of the upper shell filling block 140.

[0043] As a further optimization, the shape of the upper ring member 100 can be specifically a waist-shaped round shape, and the waist-shaped round shape specifically includes two straight edges parallel to each other, and arc-shaped edges at both ends for connecting the two straight edges, and the arc-shaped edges can specifically be semicircular. When the shape of the upper ring member 100 is a waist-shaped round shape, the shape of the chain link 300 is also correspondingly a waist-shaped round shape, so after the chain light of this embodiment is installed, in most cases, adjacent chain links 300 are always in contact at the position of the arc-shaped edges. Therefore, in order to improve the stability of the overall structure of the chain light, the installation port of the upper ring member 100 can be set on the straight edge of the waist-shaped round shape, so that after the chain light is installed, the adjacent chain links 300 will not be in contact at the position of the installation port.

[0044] As a certain embodiment of the connection method between the upper ring-forming member 100 and the lower ring-forming member 200, an upper shell connecting portion 131 may be provided on the upper shell base 130 of the upper ring-forming member 100, and a lower shell connecting portion 231 may be provided on the lower shell base 230 of the lower ring-forming member 200 at a position corresponding to the upper shell connecting portion 131. However, after the upper ring-forming member 100 and the lower ring-forming member 200 are aligned, the connection can be achieved by using the lower shell connecting portion 231 on the lower shell base 230 to cooperate with the upper shell connecting portion 131 on the upper shell base 130. For example, the upper shell connecting bolt 132 is screwed into the upper shell connecting portion 131, and is connected to the lower shell connecting portion 231 through the upper shell connecting portion 131; or the lower shell connecting bolt 232 is screwed into the lower shell connecting portion 231, and is connected to the upper shell connecting portion 131 through the lower shell connecting portion 231.

[0045] As a further optimization of this embodiment, the upper shell connection part 131 can be set at the connection position of the straight side and the arc side of the waisted round shape of the upper ring-forming member 100, and the lower shell connection part 231 can be set at the connection position of the straight side and the arc side of the waisted round shape of the lower ring-forming member 200. This can ensure that after the upper ring-forming member 100 and the lower ring-forming member 200 are matched, the position of the upper shell connection part 131 and the lower shell connection part 231 can correspond.

[0046] Further optimization is performed, the upper shell base 130 is provided with an upper shell connection part 131 at the connection position of the straight side and the arc side in its waist round shape; at the same time, the lower shell base 230 is provided with a lower shell connection part 231 at the connection position of the straight side and the arc side in its waist round shape. Therefore, when the upper ring-forming member 100 and the lower ring-forming member 200 are aligned in the forward direction or in the reverse direction, the positions of the upper shell connection part 131 and the lower shell connection part 231 can always correspond.

[0047] Among them, the positive alignment of the upper ring-forming member 100 and the lower ring-forming member 200 means that after the upper ring-forming member 100 and the lower ring-forming member 200 are aligned and connected, the installation port of the upper ring-forming member 100 corresponds to the installation port of the lower ring-forming member 200 and forms an assembly port; the reverse alignment of the upper ring-forming member 100 and the lower ring-forming member 200 means that after the upper ring-forming member 100 and the lower ring-forming member 200 are positively aligned, the upper ring-forming member 100 is rotated 180° relative to the lower ring-forming member 200 in the ring plane of the chain link 300, so that the installation port of the upper ring-forming member 100 and the installation port of the lower ring-forming member 200 are staggered.

[0048] When the upper ring member 100 and the lower ring member 200 are reversely aligned and connected, that is, in the same chain link, the two ring members rotate 180° in the ring plane of the chain link and are aligned and connected, since the installation opening of the upper ring member 100 and the installation opening of the lower ring member 200 are staggered, the straight edge of the upper ring member 100 can close the installation opening of the lower ring member 200, and the straight edge of the lower ring member 200 can close the installation opening of the upper ring member 100, thereby preventing the adjacent chain links from detaching and improving the overall stability of the chain light. At this time, the process of filling the installation opening to close the filling block plays a decorative role, that is, filling the installation opening on the chain link to form a complete ring structure.

[0049] In addition, since connecting parts are provided at the connecting positions of the straight edges and the arcuate edges in the waist-shaped shape, in the chain ring, the connecting parts located at both ends of the same arcuate edge cooperate with each other to form a locking structure, thereby clamping the adjacent chain rings between the arcuate edge and the connecting parts at both ends of the arcuate edge.

[0050] For example, in the upper ring-forming component 100, the upper shell base 130 is provided with an upper shell connection part 131 at the connection position of the straight side and the arc-shaped side of the waist-shaped circle; in the lower ring-forming component 200, the lower shell base 230 is provided with a lower shell connection part 231 at the connection position of the straight side and the arc-shaped side of the waist-shaped circle; after the upper ring-forming component 100 and the lower ring-forming component 200 are positively matched, the upper shell connection part 131 and the lower shell connection part 231 cooperate with each other to form four connection structures in parallel, and the four connection structures are formed into a locking structure in pairs, and the locking structure cooperates with the closer arc-shaped side to clamp the adjacent chain link 300.

[0051] Taking the upper ring member 100 as an example, an upper shell metal contact 150 can be set on the inner side of the arc edge of the upper shell cover 110. When the chain light is installed, the upper ring members 100 of two adjacent chain links 300 are in contact at the inner side of the arc edge, so that the upper shell metal contacts 150 of the two upper ring members 100 are electrically connected to realize power supply. Similarly, a lower shell metal contact 250 can also be set on the inner side of the arc edge of the lower ring member 200.

[0052] As a further optimization of the metal contact, taking the upper ring member 100 as an example, the upper shell metal contact 150 can be set on the upper shell base 130.

[0053] Specifically, the upper shell base 13 may be provided with a mounting groove that runs through the inner side and the lower side thereof; the upper shell metal contact 150 may be disposed in the mounting groove. When the upper shell metal contact 150 is disposed in the mounting groove, the inner side of the upper shell metal contact 150 is exposed to the inner side of the base, and the lower side of the upper shell metal contact 150 is exposed to the lower side of the base. Among them, the lower side of the upper shell metal contact 150 may contact the lower shell metal contact 250 of the lower ring-forming member 200 to realize power supply; the inner side of the upper shell metal contact 150 may contact the upper shell metal contact 150 and / or the lower shell metal contact 250 of the adjacent chain link to realize power supply.

[0054] As a further optimization, the upper shell metal contact 150 may have an extension portion, and the bottom of the mounting groove on the upper shell base 13 may be provided with an extension port that passes through the upper side surface of the upper shell base 13, and the extension portion of the upper shell metal contact 150 may enter the cavity from the extension port and be electrically connected to the upper shell light source 120 to realize power supply to the light source 120.

[0055] Reference Figure 4 The present embodiment also provides a chain light, which can be formed by a plurality of chain links 300 that are interlocked with each other, and a light-emitting portion is provided on the chain link 300, so that the chain light of the present invention has the functions of lighting, decoration and protection.

[0056] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
