Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0050] In the description of the embodiments of the present application, "a plurality of" means more than two, and unless otherwise specifically defined, "more than two" includes two. Accordingly, "a plurality of groups" means more than two groups, including two groups.

[0051] In the description of the embodiments of this application, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," and the like should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components or interaction between two components.

[0055] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0056] Please also refer to Figures 1 to 5 , Figure 1 A three-dimensional structural diagram of a splicing assembly 200 provided in some embodiments of the present application, Figure 2 This is a schematic diagram of a splicing assembly 200 provided in some embodiments of the present application, specifically a schematic diagram of the splicing assembly 200 in the axial direction Z. Figure 3 for Figure 2 Section view along AA, Figure 4 A cross-sectional view of the first connecting member 12a of the connecting rod 10 provided in some embodiments of the present application and cooperating with the splicing assembly 200. Figure 5 This is a cross-sectional view of the second connecting member 12b of the connecting rod 10 provided in some embodiments of the present application in conjunction with the splicing assembly 200. The connecting rod 10 provided in the embodiments of the present application can be used in conjunction with the splicing assembly 200, but is not limited to it.

[0057] Specifically, the splicing assembly 200 includes a plurality of splicing pieces 210, which are arranged in a sequentially close relationship along a circumferential direction a. The plurality of splicing pieces 210 are provided with limiting ribs 2120 on the same side of the axial direction Z. The limiting ribs 2120 on the same side of the plurality of splicing pieces 210 are sequentially brought together along the circumferential direction a to form a splicing ring 220. The limiting ribs 2120 of the splicing ring 220 can abut against each other sequentially along the circumferential direction a, or can be arranged at intervals.

[0058] The splicing piece 210 refers to a component that needs to be spliced. The splicing piece 210 can be a structure at a corner position of a table, a cabinet, etc., or a part of a housing, etc., which are not listed here one by one.

[0059] It can be understood that the splicing piece 210 includes a splicing body 2110 and the above-mentioned limiting ribs 2120 provided on the splicing body 2110. The splicing bodies 2110 of multiple splicing pieces 210 are arranged close to each other along the circumferential direction a, and the multiple splicing bodies 2110 are provided with limiting ribs 2120 on the same side along the axial direction Z.

[0060] The splicing body 2110 is the main body of the splicing piece 210 , and the limiting ribs 2120 refer to ribs on the splicing piece 210 used to cooperate with the connecting rod 10 to achieve relative limiting between the multiple splicing pieces 210 .

[0061] The plurality of splicing bodies 2110 are arranged close together along the circumferential direction a, which means that the two opposite sides of each splicing body 2110 along the circumferential direction a are respectively close to the two adjacent splicing bodies 2110, so that the plurality of splicing pieces 210 are distributed close together along the circumferential direction. In particular, the two adjacent splicing bodies 2110 along the circumferential direction a can abut against each other or be arranged at intervals.

[0062] The plurality of splicing bodies 2110 are provided with limiting ribs 2120 on the same side along the axial direction Z, which means that each splicing body 2110 is provided with limiting ribs 2120 on two opposite sides along the axial direction Z. Figures 1 to 5 As shown, the plurality of splicing bodies 2110 are provided with splicing rings 220 on opposite sides along the axial direction Z. Alternatively, each splicing body 2110 is provided with a limiting rib 2120, and the limiting ribs 2120 on each splicing body 2110 are located on the same side along the axial direction Z, so that the splicing ring 220 is provided on one side of the plurality of splicing bodies 2110 along the axial direction Z.

[0063] Please also refer to Figures 6 to 10 , and combined with other drawings. Among them, Figure 6 This is a three-dimensional structural diagram of the connecting rod 10 provided in some embodiments of the present application. Figure 7 for Figure 6 Exploded diagram of Figure 8 This is a three-dimensional structural diagram of the first connecting member 12a of the connecting rod 10 provided in some embodiments of the present application. Figure 9 This is a schematic diagram of the first connecting member 12a of the connecting rod 10 provided in some embodiments of the present application, specifically a schematic diagram of the first connecting member 12a in the axial direction Z. Figure 10 for Figure 9 Cross-sectional view along line BB. The connecting rod 10 provided in the embodiment of the present application includes a rod body 11 and a connecting member 12. The connecting member 12 includes a connecting body 121, which is connected to at least one end of the rod body 11 along the axial direction Z. The connecting body 121 has a roughened surface at one end away from the rod body 11 along the axial direction Z.

[0064] The rod body 11 is the main structure of the connecting rod 10, allowing it to be used as a crossbar, column, etc. The connector 12 is a connecting component of the connecting rod 10 and can be used to secure it to an external structure. The external structure can be, but is not limited to, multiple splicing pieces 210. That is, the connector 12 can be, but is not limited to, used to splice and secure multiple splicing pieces 210.

[0065] The connecting body 121 is the main body of the connecting member 12 .

[0066] At least one end of the rod body 11 along the axial direction Z is connected to the connecting body 121, which means that both opposite ends of the rod body 11 along the axial direction Z are connected to the connecting body 121. Figure 6 and Figure 7 As shown; alternatively, the rod body 11 is connected to the connecting body 121 at only one end thereof along the axial direction Z.

[0067] The surface of one end of the connecting body 121 away from the rod body 11 along the axial direction Z is roughened, which means that the surface of one end of the connecting body 121 away from the rod body 11 along the axial direction Z is a non-smooth surface, so that the surface is roughened.

[0068] The connecting rod 10 provided in the embodiment of the present application is configured to include a rod body 11 and a connecting member 12 provided at at least one end of the rod body 11 along the axial direction Z, and the surface of the connecting body 121 of the connecting member 12 at one end away from the rod body 11 along the axial direction Z is roughened. When the connecting rod 10 is fixed to an external structure via the connecting body 121, the surface of the end of the connecting body 121 away from the rod body 11 along the axial direction Z can abut against the external structure. Since the surface of the end of the connecting body 121 away from the rod body 11 along the axial direction Z is roughened, the friction between the connecting body 121 and the external structure can be increased, that is, the force between the connecting body 121 and the external structure can be increased. This helps to improve the fixing strength between the connecting body 121 and the external structure, thereby helping to improve the fixing strength of the connecting rod 10, and can improve the ease of use of the connecting rod 10.

[0069] It should be noted that when the external structure is a plurality of splicing pieces 210 arranged close to each other in sequence along the circumferential direction a, when the connecting rod 10 is fixed to the external structure through the connecting body 121, the end surface of the connecting body 121 away from the rod body 11 along the axial direction Z can abut against the plurality of splicing pieces 210, thereby increasing the friction between each splicing piece 210 and the connecting body 121, that is, increasing the interaction force between each splicing piece 210 and the connecting body 121. In this way, the fixing strength between the connecting body 121 and the plurality of splicing pieces 210 can be increased, and the splicing and fixing effect between the plurality of splicing pieces 210 can be increased, so that the connecting rod 10 can not only be used as a vertical rod or a horizontal rod, but can also be used to splice and fix a plurality of splicing pieces 210, thereby realizing the multifunctionality of the connecting rod 10.

[0070] In some embodiments, please refer to Figures 6 to 10 , and in combination with other drawings. The surface of one end of the connecting body 121 away from the rod body 11 along the axial direction Z is roughened to form a limiting rib.

[0071] The limiting rib refers to a rib structure on the surface of one end of the connecting body 121 away from the rod body 11 along the axial direction Z. The setting of the rib structure makes the surface of the end of the connecting body 121 away from the rod body 11 along the axial direction Z rough.

[0072] By providing the limiting ribs, when the connecting rod 10 is fixed to the external structure via the connecting body 121, the limiting ribs can achieve mutual limiting cooperation with the external structure, which helps to increase the force between the connecting body 121 and the external structure. This helps to improve the fixing strength between the connecting body 121 and the external structure, thereby helping to improve the fixing strength of the connecting rod 10 and improve the ease of use of the connecting rod 10.

[0073] When the external structure is a plurality of splicing pieces 210 arranged close together in sequence along the circumferential direction a, when the connecting rod 10 is fixed to the external structure through the connecting body 121, the limiting ribs can achieve limiting cooperation with the splicing rings 220 on the plurality of splicing pieces 210, thereby helping to increase the fixing strength between the connecting body 121 and the plurality of splicing pieces 210, and can increase the splicing and fixing effect between the plurality of splicing pieces 210, so that the connecting rod 10 is not only used as a vertical rod and a horizontal rod, but can also be used to splice and fix a plurality of splicing pieces 210, thereby realizing the multifunctionality of the connecting rod 10.

[0074] In some embodiments, please refer to Figures 6 to 10 , and in combination with other drawings, the limiting ribs form a limiting ring 122 .

[0075] The limiting ring 122 is a component of the connecting piece 12 used to connect and fix the multiple splicing pieces 210, and has a ring-shaped structure.

[0076] When the connecting rod 10 and the splicing assembly 200 are used together, Figure 4 and Figure 5 As shown in the figure, and in combination with other figures, the main part of the connecting body 121 is arranged on one side of the plurality of splicing bodies 2110 along the axial direction Z, and the limiting ring 122 is sleeved on the outer periphery of the splicing ring 220 on the side of the plurality of splicing pieces 210 to form relative limits on the first plane.

[0077] It should be explained that the multiple splicing bodies 2110 are sequentially brought together along the circumferential direction a to achieve relative positional restraint along the circumferential direction a. The limiting ring 122 is sleeved onto the outer circumference of the splicing ring 220 on one side of the multiple splicing pieces 210, so that the limiting ring 122 can limit the radial position of each splicing piece 210 in the radial direction b. Specifically, the inner circumferential wall of the limiting ring 122 along the radial direction b can abut against the outer circumferential wall of the splicing ring 220 along the radial direction b, so that the movement of each splicing piece 210 in the radial direction b can be restricted by the limiting ring 122. Based on this, the multiple splicing pieces 210 can be relatively restrained on the first plane.

[0078] It should be supplemented that the first plane is a plane formed by the circumferential direction a and is perpendicular to the axial direction Z.

[0079] The circumferential direction a refers to the circumferential direction of the retaining ring 122, the radial direction b refers to the radial direction of the retaining ring 122, and the axial direction Z refers to the axial direction Z of the rod body 11, which is also the longitudinal direction of the rod body 11. The axial direction Z, radial direction b, and circumferential direction a are all double-headed arrows.

[0080] When the limiting ring 122 is sleeved on the outer periphery of the splicing ring 220 of the plurality of splicing pieces 210 , the connecting body 121 can abut against one end of the splicing ring 220 close to the rod body 11 .

[0081] The connecting rod 10 provided in the embodiment of the present application is configured to include a rod body 11 and a connecting member 12 provided at at least one end of the rod body 11, and the connecting member 12 is provided with a limiting ring 122 at one end away from the rod body 11. In this way, limiting ribs 2120 can be provided on multiple splicing pieces 210 that need to be spliced ​​and fixed. The limiting ring 122 is sleeved on the limiting ribs 2120 on the multiple splicing pieces 210, and the splicing ring 220 formed by sequentially abutting against the limiting ribs 2120 on the multiple splicing pieces 210 can achieve splicing and fixing of the multiple splicing pieces 210. That is, the connecting member 12 of the connecting rod 10 can be used to conveniently achieve splicing and fixing of the multiple splicing pieces 210. With this configuration, the connecting rod 10 can not only be used as a vertical rod and a horizontal rod, but can also be used to splice and fix multiple splicing pieces 210, thereby realizing the multifunctionality of the connecting rod 10 and solving the problem of the single function of the connecting rod 10.

[0082] Moreover, by sleeve-jointing the limiting ring 122 on the outer periphery of the splicing ring 220 formed by the plurality of splicing pieces 210, the relative positioning of the plurality of splicing pieces 210 can be achieved, that is, the splicing and fixing of the plurality of splicing pieces 210 can be achieved, which makes the splicing and fixing of the plurality of splicing pieces 210 very simple and convenient, and helps to improve the splicing and fixing efficiency of the plurality of splicing pieces 210.

[0083] Furthermore, in the related art, multiple fasteners are used to sequentially secure multiple splicing pieces 210. However, due to the excessive number of connection points between the splicing pieces 210, the splicing pieces 210 require a certain thickness. However, the connecting rod 10 provided in the embodiment of the present application only requires the splicing pieces 210 to be provided with a limiting rib 2120 that can interact with the limiting ring 122 of the connecting rod 10. Furthermore, the connecting rod 10 has fewer connection points, which facilitates a thinner design for the splicing piece 210. For example, the splicing piece 210 can be used in the casing of a drone, thereby achieving a miniaturized drone design.

[0084] In some embodiments, please refer to Figures 8 to 10, and in combination with other drawings. The connecting member 12 includes a plurality of limiting rings 122, and the plurality of limiting rings 122 are sequentially arranged along the radial direction b and are spaced apart.

[0085] Specifically, the plurality of retaining rings 122 are disposed at the end of the connecting body 121 that is distal to the rod body 11 along the axial direction Z. The plurality of retaining rings 122 are sequentially arranged and spaced apart along the radial direction b. This means that the plurality of retaining rings 122 are distributed along the radial direction b, are sequentially interlocked, and are spaced apart from each other. Specifically, two adjacent retaining rings 122 along the radial direction b can be spaced apart to form an annular groove, which is used to accommodate the splicing ring 220 of the splicing assembly 200.

[0086] Accordingly, multiple splicing rings 220 can be provided on one side of the multiple splicing bodies 2110 close to the connecting body 121 along the axial direction Z. The multiple splicing rings 220 on this side are arranged in a circle in sequence and at intervals. Furthermore, each limiting ring 122 is provided in a one-to-one correspondence with each splicing ring 220 on this side, and each limiting ring 122 is sleeved on the outer circumference of each splicing ring 220 on this side.

[0087] Such an arrangement can improve the splicing and fixing effect of the multiple splicing pieces 210.

[0088] In some embodiments, please refer to Figures 8 to 10 In the direction in which the limiting ring 122 moves away from the rod body 11 along the axial direction Z, the limiting ring 122 is gradually contracted along at least one side of the radial direction b.

[0089] Among some possible designs, such as Figures 8 to 10 As shown, and combined Figure 4 、 Figure 5 As the limiting ring 122 moves away from the rod body 11 along the axial direction Z, the inner peripheral wall of the limiting ring 122 is gradually reduced along the radial direction b. The inner peripheral wall of the limiting ring 122 is annular, and the surface shape can be an inclined surface, an arc surface, etc.

[0090] Correspondingly, the outer circumferential wall of the corresponding splicing ring 220 can be configured to match the shape of the inner circumferential wall of the limiting ring 122. Specifically, the outer circumferential wall of the splicing ring 220 is configured to be tapered in the direction of the limiting ring 122 on this side pointing toward the rod body 11 along the axial direction Z. The outer circumferential wall of the splicing ring 220 is annular in shape, and its surface shape is substantially the same as that of the inner circumferential wall of the limiting ring 122, and can be a bevel, a curved surface, or the like.

[0091] This arrangement allows the outer circumferential wall of the splicing ring 220 to guide the limiting ring 122, facilitating the limiting ring 122's sleeve engagement with the outer circumference of the splicing ring 220, thereby facilitating the connection rod 10 in the splicing and securing of multiple splicing pieces 210. Furthermore, the inner circumferential wall of the limiting ring 122 can abut against and compress the outer circumferential wall of the splicing ring 220, thereby enhancing the radial position b limiting effect of the limiting ring 122 on the splicing ring 220.

[0092] Among some possible designs, such as Figures 8 to 10 As shown, and combined Figure 4 、 Figure 5 As the limiting ring 122 moves away from the rod body 11 along the axial direction Z, the outer peripheral wall of the limiting ring 122 along the radial direction b is gradually reduced. The outer peripheral wall of the limiting ring 122 is annular, and the surface shape can be an inclined surface, an arc surface, etc.

[0093] Correspondingly, the inner circumferential wall of the corresponding splicing ring 220 can be adapted to the shape of the outer circumferential wall of the limiting ring 122. Specifically, the inner circumferential wall of the splicing ring 220 on this side is tapered in the direction of the rod body 11 along the axial direction Z. The inner circumferential wall of the splicing ring 220 is annular and has a surface shape that is substantially the same as that of the inner circumferential wall of the limiting ring 122, and can be a bevel, a curved surface, or the like.

[0094] Such a configuration allows the inner circumferential wall of the splicing ring 220 to guide the limiting ring 122 , making it easier for the limiting ring 122 to be sleeved on the outer circumference of the splicing ring 220 , thereby facilitating the assembly of components to achieve splicing and fixing operations of multiple splicing pieces 210 .

[0095] In some embodiments, please refer to Figure 6 and Figure 7 The connecting rod 10 includes two connecting members 12 , and the connecting bodies 121 of the two connecting members 12 are respectively provided at opposite ends of the rod body 11 along the axial direction Z.

[0096] Such an arrangement enables the connecting pieces 12 at both opposite ends of the rod body 11 along the axial direction Z to be used for splicing and fixing the multiple splicing pieces 210 .

[0097] In some embodiments, please refer to Figures 8 to 10 At least one connecting member 12 is a first connecting member 12a, and the first connecting member 12a further includes a first connecting portion 123. The first connecting portion 123 extends from an end of the connecting body 121 away from the rod body 11, and a limiting ring 122 is arranged around the outer periphery of the first connecting portion 123.

[0098] Specifically, the first connecting portion 123 is disposed on the connecting body 121 and extends along the axial direction Z from an end of the connecting body 121 away from the rod body 11 .

[0099] With this arrangement, when the limiting ring 122 of the first connecting member 12a is sleeved on the outer circumference of the splicing rings 220 of the plurality of splicing pieces 210, the first connecting portion 123 can be used to connect with other components, so that the first connecting member 12a can axially limit the plurality of splicing pieces 210. The other component may be, but is not limited to, the second connecting member 12b of another connecting rod 10.

[0100] For example, when the limiting ring 122 of the first connecting member 12a is sleeved on the outer periphery of the splicing ring 220 of multiple splicing members 210, the connecting body 121 of the first connecting member 12a can abut against one end of the splicing ring 220 close to the rod body 11 to perform axial Z-limitation on the multiple splicing members 210.

[0101] It should be noted that the plurality of splicing bodies 2110 can be arranged to surround a through hole 2001, and the splicing ring 220 is disposed around the outer periphery of the through hole 2001. In this way, when the retaining ring 122 of the first connecting member 12a is sleeved on the outer periphery of the splicing rings 220 of the plurality of splicing members 210, the first connecting portion 123 is disposed along the axial direction Z through the through hole 2001, thereby enabling the first connecting portion 123 to be fixed to other components.

[0102] In some embodiments, an outer circumference of the first connection portion 123 is provided with an external thread.

[0103] This arrangement allows the first connecting portion 123 to be connected to other components via a threaded connection, which may be, but is not limited to, the second connecting member 12b described below. This facilitates the positioning of the multiple splicing pieces 210 in the axial direction Z, thereby facilitating the splicing and fixing of the multiple splicing pieces 210 and improving the splicing and fixing effect of the multiple splicing pieces 210.

[0104] In some embodiments, please refer to Figures 11 to 13 , and combined with other drawings. Among them, Figure 11 This is a three-dimensional structural diagram of the second connecting member 12b of the connecting rod 10 provided in some embodiments of the present application. Figure 12 This is a schematic diagram of the second connecting member 12b of the connecting rod 10 provided in some embodiments of the present application, specifically a schematic diagram of the second connecting member 12b in the axial direction Z. Figure 13 for Figure 12 Cross-sectional view along CC. At least one connecting member 12 is a second connecting member 12b. The connecting body 121 of the second connecting member 12b is provided with a threaded hole 12101 at one end away from the rod body 11. The threaded hole 12101 is provided with an internal thread.

[0105] With this arrangement, when the limiting ring 122 of the second connecting member 12b is sleeved on the outer circumference of the splicing rings 220 of the plurality of splicing members 210, the threaded hole 12101 can be used to connect with other components, so that the second connecting member 12b can axially limit the Z position of the plurality of splicing members 210. The other component may be, but is not limited to, the first connecting portion 123 of the first connecting member 12a of the other connecting rod 10.

[0106] For example, when the limiting ring 122 of the second connecting member 12b is sleeved on the outer circumference of the splicing ring 220 of the plurality of splicing members 210 , the connecting body 121 of the second connecting member 12b can abut against one end of the splicing ring 220 close to the rod body 11 .

[0107] It should be noted that the plurality of splicing bodies 2110 can be arranged to surround a through hole 2001, and the splicing ring 220 can be arranged around the outer periphery of the through hole 2001. In this way, when the retaining ring 122 of the second connecting member 12b is sleeved on the outer periphery of the splicing rings 220 of the plurality of splicing members 210, other components can be inserted into the through hole 2001 along the axial direction Z, thereby enabling the threaded hole 12101 to be fixed to the other components.

[0108] Based on the above structure, when there are multiple connecting rods 10, the rod bodies 11 of the multiple connecting rods 10 can be distributed along the axial direction Z. In addition, in two adjacent connecting rods 10, the first connecting portion 123 of the first connecting member 12a of one connecting rod 10 can be inserted into the threaded hole 12101 of the second connecting member 12b of the other connecting rod 10 to achieve a threaded connection. In this way, multiple connecting rods 10 can be spliced ​​along the axial direction Z.

[0109] A splicing assembly 200 may be provided between two adjacent connecting rods 10 along the axial direction Z. Specifically, a plurality of splicing pieces 210 may be provided with limiting ribs 2120 on opposite sides along the axial direction Z, so that the plurality of splicing pieces 210 on opposite sides along the axial direction Z are combined to form a splicing ring 220.

[0110] For the convenience of description, two adjacent connecting rods 10 are defined as a first connecting rod 10 a and a second connecting rod 10 b .

[0111] like Figure 15 As shown in the accompanying drawings, and in combination with other drawings. Figure 15A partial cross-sectional view of a modular rod structure 100 and a splicing assembly 200 provided in some embodiments of the present application. The connecting body 121 of the first connecting member 12a of the first connecting rod 10a is disposed on one side of the plurality of splicing members 2110 along the axial direction Z, while the connecting body 121 of the second connecting member 12b of the second connecting rod 10b is disposed on the other side of the plurality of splicing members 2110 along the axial direction Z. The first connecting member 12a of the first connecting rod 10a is sleeved onto the outer circumference of the splicing ring 220 on one side of the plurality of splicing members 210, while the second connecting member 12b of the second connecting rod 10b is sleeved onto the outer circumference of the splicing ring 220 on the other side of the plurality of splicing members 210. The first connecting portion 123 of the first connecting piece 12a of the first connecting rod 10a is passed through the through hole 2001 formed by the combination of multiple splicing pieces 210, and is threadedly connected to the threaded hole 12101 of the second connecting piece 12b of the second connecting rod 10b, thereby realizing the connection between the first connecting piece 12a of the first connecting rod 10a and the second connecting piece 12b of the second connecting rod 10b.

[0112] It should be explained that the multiple splicing bodies 2110 are sequentially brought together along the circumferential direction a so that the multiple splicing bodies 2110 are relatively limited along the circumferential direction a. The first connecting member 12a of the first connecting rod 10a is sleeved on the outer periphery of the splicing ring 220 on one side of the multiple splicing pieces 210, and the second connecting member 12b of the second connecting rod 10b is sleeved on the outer periphery of the splicing ring 220 on the other side of the multiple splicing pieces 210 so that each splicing piece 210 is limited in radial direction b. Specifically, the inner circumferential wall of the limiting ring 122 along radial direction b can abut against the outer circumferential wall of the splicing ring 220 along radial direction b, so that the movement of each splicing piece 210 along radial direction b can be restricted by the limiting ring 122. Based on this, the multiple splicing pieces 210 can be relatively limited on the first plane.

[0113] The connecting body 121 of the first connecting member 12a of the first connecting rod 10a and the connecting body 121 of the second connecting member 12b of the second connecting rod 10b can respectively abut against opposite ends of the plurality of splicing pieces 210 along the axial direction Z. Specifically, the connecting body 121 of the first connecting member 12a of the first connecting rod 10a abuts against the splicing ring 220 on one side of the plurality of splicing pieces 210 along the axial direction Z, and the connecting body 121 of the second connecting member 12b abuts against the splicing ring 220 on the other side of the plurality of splicing pieces 210 along the axial direction Z. Furthermore, the first connecting member 12a of the first connecting rod 10a and the second connecting member 12b of the second connecting rod 10b are interconnected so that the plurality of splicing pieces 210 can be limited in the axial direction Z between the connecting body 121 of the first connecting member 12a of the first connecting rod 10a and the connecting body 121 of the second connecting member 12b of the second connecting rod 10b. Based on this, the plurality of splicing pieces 210 can be limited in the axial direction Z.

[0114] With such an arrangement, two adjacent connecting rods 10 can be spliced ​​in the axial direction Z, and can jointly implement the splicing and fixing operation of the splicing assembly 200 .

[0115] In some embodiments, please refer to Figures 11 to 13 , and in combination with other drawings. The connecting body 121 of the second connecting member 12b includes a second connecting portion 1211 and a screw sleeve 1212. The second connecting portion 1211 is connected to the rod body 11. The limiting ring 122 of the second connecting member 12b is provided at the end of the second connecting portion 1211 away from the rod body 11. The second connecting portion 1211 is provided with an assembly hole at the end away from the rod body 11. The screw sleeve 1212 is provided in the assembly hole, and the screw sleeve 1212 forms a threaded hole 12101.

[0116] When the limiting ring 122 of the second connecting member 12 b is sleeved on the splicing rings 220 of the plurality of splicing members 210 , the second connecting portion 1211 of the second connecting member 12 b may abut against the limiting ring 122 on that side.

[0117] The threaded sleeve 1212 may be, but is not limited to, a wire threaded sleeve 1212 .

[0118] It can be understood that when two adjacent connecting rods 10 are combined, the first connecting portion 123 of the first connecting member 12 a can be inserted into the assembly hole to be threadedly connected to the screw sleeve 1212 .

[0119] Such a configuration facilitates the provision of a screw sleeve 1212 with greater rigidity, can improve the connection strength between the first connecting member 12a and the second connecting member 12b, and can improve the splicing and fixing strength and stability of the plurality of splicing members 210.

[0120] In some embodiments, the limiting rings 122 of the two connecting members 12 are arranged in mirror symmetry.

[0121] The limiting rings 122 of the two connecting parts 12 are arranged in a mirror-symmetrical manner, which means that the limiting rings 122 of the two connecting parts 12 are arranged in a mirror-symmetrical manner relative to the axis where the radial direction b is located. It can also be understood that the limiting rings 122 of the two connecting parts 12 are arranged in a mirror-symmetrical manner relative to the first plane.

[0122] Such an arrangement allows the splicing rings 220 on opposite sides of the multiple splicing bodies 2110 along the axial direction Z to be arranged in a mirror-symmetrical manner, so that when the connecting rod 10 and the splicing assembly 200 are used to cooperate with each other, there is no need to distinguish between the front and back sides of the splicing piece 210, which facilitates the assembly of the assembly to achieve the splicing and fixing operation of multiple splicing pieces 210.

[0123] Please also refer to Figure 14 and Figure 15 , and combined with other drawings. Among them, Figure 14This is a three-dimensional structural diagram of a combination rod structure 100 provided in some embodiments of the present application in conjunction with other structures. The combination rod structure 100 provided in the embodiments of the present application includes a plurality of connecting rods 10, with rod bodies 11 of at least some of the connecting rods 10 distributed along the axial direction Z. The connecting rods 10 in this embodiment are identical to the connecting rods 10 in the above embodiments. For details, please refer to the relevant descriptions of the connecting rods 10 in the above embodiments and will not be repeated here.

[0124] The connecting rod 10 includes two connecting members 12, namely a first connecting member 12a and a second connecting member 12b, which are respectively provided at opposite ends of the rod body 11 along the axial direction Z. That is, the opposite ends of each connecting rod 10 along the axial direction Z are respectively connected to the first connecting member 12a and the second connecting member 12b.

[0125] The first connecting member 12a further includes a first connecting portion 123, which extends from the end of the connecting body 121 away from the rod body 11. A retaining ring 122 is disposed around the outer periphery of the first connecting portion 123. Specifically, the first connecting portion 123 is disposed on the connecting body 121 and extends in the axial direction Z from the end of the connecting body 121 having the retaining ring 122.

[0126] The connecting body 121 of the second connecting member 12 b has a threaded hole 12101 at one end away from the rod body 11 , and the first connecting portion 123 is used for threaded connection with the threaded hole 12101 .

[0127] Of the two connecting rods 10 adjacent to each other along the axial direction Z, the first connecting portion 123 of one connecting rod 10 is threadedly connected to the threaded hole 12101 of the other connecting rod 10 .

[0128] The combination rod structure 100 provided in the embodiment of the present application adopts the connecting rod 10 involved in the above embodiments, so that the connecting rod 10 has a high fixing strength. In this way, on the basis of multiple connecting rods 10 being spliced ​​along the axial direction Z to form the combination rod structure 100, it helps to increase the structural strength and stability of the combination rod structure 100.

[0129] Furthermore, the roughened surface of the end of the connecting body 121 away from the rod body 11 in the axial direction Z forms a retaining ring 122, which allows the retaining ring 122 to be used to securely connect multiple splicing pieces 210. This allows the connecting rod 10 to function not only as a vertical rod and a horizontal rod, but also to securely connect multiple splicing pieces 210. Furthermore, multiple connecting rods 10 can be connected in the axial direction Z. This arrangement achieves multifunctionality in the connecting rod 10.

[0130] It should be noted that the combined rod structure 100 can be used to realize the splicing of multiple frames 300 in the axial direction Z.

[0131] The frame 300 may include two first side beams 310, two second side beams 320, and four splicing assemblies 200. The two first side beams 310 are spaced apart along the second direction Y, and the two second side beams 320 are spaced apart along the third direction. The four splicing assemblies 200 are respectively disposed at opposite ends of the two first side beams 310, and two of the splicing bodies 2110 of the splicing assemblies 200 are respectively connected to the first side beams 310 and the second side beams 320. The axial direction Z intersects the first direction X, the axial direction Z intersects the second direction Y, and the first direction X intersects the second direction Y.

[0132] It can be understood that, of the opposite ends of one of the first side beams 310, one end is connected to one end of one of the second side beams 320, and the other end is connected to one end of another second side beam 320. Of the opposite ends of another first side beam 310, one end is connected to the other end of one of the second side beams 320, and the other end is connected to the other end of another second side beam 320. The above connection refers to an indirect connection through the splicing assemblies 200 and the connecting rod 10. Specifically, among the four splicing assemblies 200, two splicing assemblies 200 are respectively provided at the opposite ends of one of the first side beams 310, and the other two splicing assemblies 200 are respectively provided at the opposite ends of another first side beam 310.

[0133] It can be understood that two of the splicing bodies 2110 of each splicing assembly 200 are respectively connected to the first side beam 310 and the second side beam 320 to achieve an indirect connection between the first side beam 310 and the second side beam 320 .

[0134] It can be understood that the two first side beams 310 and the two second side beams 320 are arranged in a crisscross manner so that the frame 300 is roughly square, and the two first side beams 310 and the two second side beams 320 are the four sides of the square structure.

[0135] The intersection of the first direction X and the second direction Y means that the first direction X and the second direction Y can form an angle greater than 0° and less than 180°, that is, the first direction X and the second direction Y are not parallel. The first direction X and the second direction Y can be perpendicular to each other, or they can be non-perpendicular. The first direction X and the second direction Y can be directions that intersect on the same plane, or they can be directions on planes that are not parallel to each other, and the projection of the second direction Y on the plane where the first direction X is located can intersect with the first direction X. Correspondingly, the meaning of the intersection of the first direction X and the axial direction Z and the intersection of the second direction Y and the axial direction Z can also be interpreted in the same way, and will not be repeated here. As an example, the first direction X and the second direction Y are perpendicular, the first direction X is perpendicular to the axial direction Z, and the second direction Y is perpendicular to the axial direction Z.

[0136] The first direction X and the second direction Y are both double-arrow directions.

[0137] The frame 300 provided in the embodiment of the present application may be a photo frame, or a frame 300 of a cabinet, etc.

[0138] When there are multiple frames 300, the multiple frames 300 can be spaced apart along the axial direction Z. In two adjacent connecting rods 10, the first connecting member 12a of the first connecting rod 10a and the second connecting member 12b of the second connecting rod 10b can cooperate with the splicing assembly 200 of the first frame 300, the second connecting member 12b of the first connecting rod 10a can cooperate with the splicing assembly 200 of the second frame 300, and the first connecting member 12a of the second connecting rod 10b can cooperate with the splicing assembly 200 of the third frame 300. In this way, a combination of three frames 300 in the axial direction Z can be achieved.

[0139] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
