[0065] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0066] In the description of the embodiments of the present application, "multiple" means more than two, and unless otherwise clearly and specifically defined, "more than two" includes two. Accordingly, "multiple groups" means more than two groups, including two groups.

[0067] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0071] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0072] Please also read Figures 1 to 3 , Figure 1 A three-dimensional structural diagram of a splicing structure 10 provided in some embodiments of the present application, Figure 2 for Figure 1 An exploded diagram of Figure 3for Figure 1 Cross-sectional view along AA. The splicing structure 10 provided in the embodiment of the present application includes a limiter 12 and a plurality of splicing pieces 11. The plurality of splicing pieces 11 are arranged close to each other in sequence along the circumferential direction a. The plurality of splicing pieces 11 are provided with limiter ribs 111 on the same side along the first direction Z, and the first direction Z is perpendicular to the first plane formed by the circumferential direction a. The limiter 12 cooperates with the limiter ribs 111 to form relative limits on the first plane.

[0073] The splicing piece 11 refers to a component that needs to be spliced. The splicing piece 11 can be a structure at a corner of a table, a cabinet, etc., or a part of a housing, etc., which are not listed here one by one.

[0074] The multiple splicing pieces 11 are arranged close to each other in the circumferential direction a, which means that the multiple splicing pieces 11 are roughly distributed along the circumferential direction a, and the two opposite sides of each splicing piece 11 along the circumferential direction a are respectively close to the two adjacent splicing pieces 11, so that the multiple splicing pieces 11 are roughly distributed close to each other in the circumferential direction. Among them, the two adjacent splicing pieces 11 along the circumferential direction a can abut against each other along the circumferential direction a, or can be arranged at intervals.

[0075] The limiting ribs 111 refer to ribs on the splicing piece 11 that are used to cooperate with the limiting piece 12 to achieve relative limiting between the multiple splicing pieces 11 .

[0076] The plurality of splicing pieces 11 are provided with limiting ribs 111 on the same side along the first direction Z, which means that each splicing piece 11 is provided with limiting ribs 111 on two opposite sides along the first direction Z. Figures 1 to 3 As shown; or, each splicing piece 11 is provided with a limiting rib 111, and the limiting rib 111 of each splicing piece 11 is located on the same side along the first direction Z.

[0077] It can be understood that the splicing piece 11 can include a splicing body 112 and a limiting rib 111 arranged on the splicing body 112, the splicing bodies 112 of multiple splicing pieces 11 are arranged close to each other in sequence along the circumferential direction a, and the limiting rib 111 is provided on the same side of the splicing bodies 112 of multiple splicing pieces 11.

[0078] The plurality of assembling pieces 11 are relatively limited on the first plane, which means that the relative movement of the plurality of assembling pieces 11 on the first plane is restricted.

[0079] Among some possible designs, such as Figures 1 to 3As shown, each splicing piece 11 is provided with a limiting rib 111 on two opposite sides along the first direction Z, and the number of the limiting members 12 is two, one of the limiting members 12 is limitedly matched with the limiting rib 111 on one side of each splicing piece 11 along the first direction Z, and the other limiting member 12 is limitedly matched with the limiting rib 111 on the other side of each splicing piece 11 along the first direction Z. Alternatively, in some other possible designs, each splicing piece 11 is provided with a limiting rib 111 on one side along the first direction Z, and the number of the limiting member 12 is one, and the limiting member 12 is limitedly matched with the limiting rib 111 of each splicing piece 11.

[0080] The first direction Z is perpendicular to the first plane, which means it is approximately perpendicular, not absolutely perpendicular.

[0081] The splicing structure 10 provided in the embodiment of the present application can make the multiple splicing pieces 11 form relative limits on the first plane by bringing the multiple splicing pieces 11 closer in sequence along the circumferential direction a, and the limiting piece 12 cooperates with the limiting ribs 111 on the multiple splicing pieces 11, thereby achieving the splicing and fixing effect of the multiple splicing pieces 11. In this way, the operation of fixing with multiple fasteners is saved, which helps to simplify the splicing and fixing operation of the multiple splicing pieces 11 and improve the splicing and fixing efficiency of the multiple splicing pieces 11.

[0082] In addition, in the related art, a solution of using multiple fasteners to sequentially fix multiple splicing pieces 11 requires a certain thickness of the splicing pieces 11 because there are too many connection positions between the splicing pieces 11. However, the splicing structure 10 provided in the embodiment of the present application only requires the splicing pieces 11 to be provided with a limiting rib 111 that cooperates with the limiting piece 12, and there are fewer connection positions, which facilitates the splicing piece 11 to achieve a thinner design. For example, the splicing piece 11 can be used in the casing of a drone, etc., to achieve a miniaturized design of the drone.

[0083] In some embodiments, please refer to Figures 4 to 10 , and combined with other drawings. Among them, Figure 4 A schematic diagram of splicing a plurality of splicing pieces 11 of a splicing structure 10 provided in some embodiments of the present application, Figure 5 for Figure 4 Cross-sectional view along BB, Figure 6 A three-dimensional structural diagram of a first stopper 12a of a splicing structure 10 provided in some embodiments of the present application, Figure 7 for Figure 6 , specifically a schematic diagram of the first limiting member 12a in the first direction Z, Figure 8 for Figure 7 Cross-sectional view along CC, Fig. 9 A schematic diagram of a second position-limiting member 12b of a splicing structure 10 provided in some embodiments of the present application, specifically a schematic diagram of the second position-limiting member 12b in a first direction Z, Fig.10for Fig. 9 The sectional view along DD. The splicing structure 10 comprises two limiting members 12 , and limiting ribs 111 are provided on opposite sides of the splicing member 11 along the first direction Z. The two limiting members 12 cooperate with the limiting ribs 111 on opposite sides of the splicing member 11 .

[0084] The two limiting members 12 respectively cooperate with the limiting ribs 111 on the opposite sides of the splicing piece 11, which means that the two limiting members 12 correspond to the limiting ribs 111 on the opposite sides of the splicing piece 11, one of the limiting members 12 cooperates with the limiting rib 111 on one side of the splicing piece 11 along the first direction Z, and the other limiting rib 111 cooperates with the limiting rib 111 on the other side of the splicing piece 11 along the first direction Z.

[0085] With such arrangement, the two limiting members 12 can both achieve relative limiting of the plurality of assembling members 11 in the first direction Z, thereby improving the splicing and fixing effect of the plurality of assembling members 11 .

[0086] In some embodiments, please refer to Figures 4 to 10 The limiting ribs 111 on the same side of the plurality of splicing pieces 11 are brought together in the circumferential direction a to form a first limiting ring 104 . The limiting piece 12 includes a second limiting ring 121 , which is sleeved on the outer circumference of the corresponding first limiting ring 104 .

[0087] In some possible designs, each splicing piece 11 is provided with a limiting rib 111 on both sides of the first direction Z. The limiting ribs 111 on one side of the multiple splicing pieces 11 along the first direction Z are brought closer in sequence along the circumferential direction a to form a first limiting ring 104; the limiting ribs 111 on the other side of the multiple splicing pieces 11 along the first direction Z are also brought closer in the circumferential direction a to form a first limiting ring 104. There are two limiting pieces 12, wherein the second limiting ring 121 of one limiting piece 12 is sleeved on the outer periphery of the first limiting ring 104 on one side of the multiple splicing pieces 11, and the second limiting ring 121 of the other limiting piece 12 is sleeved on the outer periphery of the first limiting ring 104 on the other side of the multiple splicing pieces 11.

[0088] Alternatively, in some other possible designs, each assembling piece 11 is provided with a limiting rib 111 on one side along the first direction Z, and the limiting ribs 111 of the plurality of assembling pieces 11 are successively brought together along the circumferential direction a to form a first limiting ring 104 .

[0089] It can be understood that a first limiting ring 104 includes a plurality of limiting ribs 111 arranged substantially along the circumferential direction a. In the first limiting ring 104, two adjacent limiting ribs 111 along the circumferential direction a may abut against each other along the circumferential direction a, or may be arranged at intervals.

[0090] As an example, the limiting ribs 111 on the same side of the plurality of splicing pieces 11 abut against each other in sequence along the circumferential direction a to form a first limiting ring 104 .

[0091] The first limiting ring 104 refers to an annular rib, that is, a plurality of limiting ribs 111 are combined to form the first limiting ring 104 .

[0092] The second limiting ring 121 is an annular structure, and the second limiting ring 121 is sleeved on the outer circumference of the corresponding first limiting ring 104, so that the second limiting ring 121 can limit the radial direction b of the splicing piece 11. Specifically, the outer circumferential wall of each first limiting ring 104 along the radial direction b can abut against the inner circumferential wall of the second limiting ring 121 along the radial direction b, so that the movement of the splicing piece 11 along the radial direction b can be limited by the second limiting ring 121.

[0093] The circumferential direction a may be the circumferential direction of the first limiting ring 104 and the second limiting ring 121, and the radial direction b may be the radial direction of the first limiting ring 104 and the second limiting ring 121. Both the radial direction b and the circumferential direction a are perpendicular to the first direction Z.

[0094] The second limiting ring 121 is sleeved on the outer circumference of the first limiting ring 104, so that the second limiting ring 121 can limit the first limiting ring 104 in the radial direction b, that is, the splicing piece 11 can be limited in the radial direction b. The multiple splicing pieces 11 are arranged close to each other in the circumferential direction a, so that the multiple splicing pieces 11 can be abutted in the circumferential direction a in turn, so that the multiple splicing pieces 11 can be limited in the circumferential direction a. In this way, the multiple splicing pieces 11 are limited in the first plane.

[0095] In some embodiments, please refer to Figures 4 to 10 , and in combination with other drawings. The outer peripheral wall of the first limiting ring 104 is gradually contracted outwardly along the first direction Z, and the inner peripheral wall of the second limiting ring 121 is adapted to the outer peripheral wall of the first limiting ring 104 in shape.

[0096] The outer peripheral wall of the first limiting ring 104 refers to the outer peripheral wall of the first limiting ring 104 along the radial direction b.

[0097] The outer peripheral wall of the first limit ring 104 is set to be gradually contracted outward along the first direction Z, which means that in the first direction Z, the outer peripheral wall of the first limit ring 104 is set to be gradually contracted in the direction away from the splicing body 112, that is, the first limit ring 104 is set to be gradually contracted in the direction away from the splicing body 112 by the extension of the outer peripheral wall of the first limit ring 104. It can be understood that whether the outer peripheral wall of the first limit ring 104 is set to be gradually contracted or gradually expanded mainly depends on whether the first limit ring 104 is gradually contracted or gradually expanded under the extension of the outer peripheral wall. Among them, the outer peripheral wall of the first limit ring 104 is annular, and the surface shape can be an inclined surface, an arc surface, etc.

[0098] The inner circumferential wall of the second limiting ring 121 refers to the inner circumferential wall of the second limiting ring 121 along the radial direction b.

[0099] The inner circumferential wall of the second limiting ring 121 is adapted to the outer circumferential wall of the first limiting ring 104, so that in the first direction Z, the inner circumferential wall of the second limiting ring 121 is gradually contracted toward the direction close to the splicing body 112. Similarly, the inner circumferential wall of the second limiting ring 121 is extended so that the second limiting ring 121 is gradually contracted toward the direction close to the splicing body 112. The inner circumferential wall of the second limiting ring 121 is annular, and the surface shape is substantially the same as the surface shape of the outer circumferential wall of the first limiting ring 104, which can be an inclined surface, an arc surface, etc.

[0100] Such a configuration allows the outer circumferential wall of the first limiting ring 104 to guide the second limiting ring 121, so that the second limiting ring 121 can be sleeved on the outer circumference of the first limiting ring 104, thereby facilitating the limiting member 12 to realize the splicing and fixing operation of multiple splicing members 11. In addition, the inner circumferential wall of the second limiting ring 121 can abut against and squeeze the outer circumferential wall of the first limiting ring 104, so as to improve the radial b limiting effect of the second limiting ring 121 on the first limiting ring 104.

[0101] The second limiting rings 121 correspond to the first limiting rings 104 one by one, and the second limiting rings 121 are sleeved on the outer circumference of the first limiting rings 104 .

[0102] Based on this, the inner circumferential wall of the second limiting ring 121 is configured to match the shape of the outer circumferential wall of the corresponding first limiting ring 104 .

[0103] In some embodiments, please refer to Figures 4 to 10 , and in combination with other drawings, the outer ring diameter of the first limiting ring 104 is greater than the inner ring diameter of the corresponding second limiting ring 121 .

[0104] The outer ring diameter of the first limiting ring 104 refers to the diameter of the outer peripheral wall of the first limiting ring 104 , which is the first diameter D1 .

[0105] The inner ring diameter of the second limiting ring 121 refers to the diameter of the inner circumferential wall of the second limiting ring 121 , which is the second diameter D2 .

[0106] By setting the first diameter D1 to be larger than the second diameter D2, when the second stop ring 121 is sleeved on the outer periphery of the first stop ring 104, the inner peripheral wall of the second stop ring 121 abuts against and squeezes the outer peripheral wall of the first stop ring 104, so that a pre-tightening force along the radial direction b can be provided to the first stop ring 104, thereby providing a pre-tightening force to bring the multiple splicing pieces 11 closer to each other. It can be understood that the hole defined by the inner peripheral wall of the second stop ring 121 and the first stop ring 104 are interference fit. Such a setting can improve the splicing and fixing strength of the multiple splicing pieces 11.

[0107] In some embodiments, please refer to Figures 4 to 10 , and in combination with other drawings. The limiting member 12 further includes a first connecting portion 122 connected to the second limiting ring 121 , and the first connecting portion 122 and the first limiting ring 104 abut against each other along the first direction Z.

[0108] As an example, the second limiting ring 121 is arranged on one side of the first connection part 122 along the first direction Z, and when the second limiting ring 121 is sleeved on the outer periphery of the first limiting ring 104, the side of the first connection part 122 having the second limiting ring 121 can be against the first limiting ring 104 along the first direction Z.

[0109] Such an arrangement facilitates the arrangement of a plurality of second limiting rings 121 on the limiting member 12 .

[0110] In some embodiments, please refer to Figures 4 to 10 , and in combination with other drawings. The limiting ribs 111 on the same side of the multiple splicing pieces 11 are successively close to each other along the circumferential direction a to form multiple first limiting rings 104, and the multiple first limiting rings 104 on the same side are successively arranged and spaced along the radial direction b. The limiting piece 12 includes multiple second limiting rings 121, and the multiple second limiting rings 121 are successively arranged and spaced along the radial direction b. Each second limiting ring 121 is sleeved on the outer circumference of each first limiting ring 104.

[0111] Among some possible designs, such as Figures 4 to 10 As shown, each splicing piece 11 is provided with a limiting rib 111 on both sides of the first direction Z, and the limiting ribs 111 on one side of the multiple splicing pieces 11 along the first direction Z are successively close to each other along the circumferential direction a to form a plurality of first limiting rings 104, and the plurality of first limiting rings 104 on this side are successively arranged and spaced; the limiting ribs 111 on the other side of the multiple splicing pieces 11 along the first direction Z are also close to each other along the circumferential direction a to form a plurality of first limiting rings 104, and the plurality of first limiting rings 104 on this side are successively arranged and spaced. There are two limiting pieces 12, and the plurality of second limiting rings 121 of one limiting piece 12 are sleeved one-to-one on the outer periphery of the plurality of first limiting rings 104 on one side of the splicing piece 11, and the plurality of second limiting rings 121 of the other limiting piece 12 are also sleeved one-to-one on the outer periphery of the plurality of first limiting rings 104 on the other side of the multiple splicing pieces 11.

[0112] Alternatively, in some other possible designs, each splicing piece 11 is provided with a limiting rib 111 on one side along the first direction Z, and the limiting ribs 111 of the plurality of splicing pieces 11 are successively brought closer along the circumferential direction a to form a plurality of first limiting rings 104 .

[0113] As an example, the limiting ribs 111 on the same side of the plurality of splicing pieces 11 abut against each other in sequence along the circumferential direction a to form a plurality of first limiting rings 104 .

[0114] The multiple first limiting rings 104 on the same side are sequentially arranged and spaced along the radial direction b, which means that the multiple first limiting rings 104 on the same side are sequentially connected and spaced from each other. The multiple first limiting rings 104 on the same side are spaced from each other, so that two adjacent first limiting rings 104 along the radial direction b can be spaced to form an annular groove (the limiting groove 101 mentioned below), and the annular groove is used for the second limiting ring 121 to enter.

[0115] The plurality of second limiting rings 121 are arranged in sequence and spaced along the radial direction b, which means that the plurality of second limiting rings 121 are sleeved in sequence and spaced from each other in pairs. The plurality of second limiting rings 121 are spaced from each other in pairs, so that two second limiting rings 121 adjacent to each other in the radial direction b can be spaced to form an annular groove, and the annular groove is used for the first limiting ring 104 to enter.

[0116] The second limiting rings 121 correspond to the first limiting rings 104 one by one, and the second limiting rings 121 are sleeved on the outer circumference of the first limiting rings 104 .

[0117] In some embodiments, please refer to Figures 4 to 10 , and in combination with other drawings. Two adjacent first limiting rings 104 on the same side are spaced apart to form a limiting groove 101, and the limiting groove 101 has an outer groove wall 1011 and an inner groove wall 1012 opposite to each other along the radial direction b. The outer groove wall 1011 is gradually expanded outward along the first direction Z, and the outer peripheral wall of the second limiting ring 121 is adapted to the shape of the outer groove wall 1011.

[0118] Among them, among the two first limiting rings 104 that form the limiting groove 101, the inner circumferential wall of the first limiting ring 104 located on the outer side of the radial direction b is the outer groove wall 1011 of the limiting groove 101, and the outer circumferential wall of the first limiting ring 104 located on the inner side of the radial direction b is the inner groove wall 1012 of the limiting groove 101.

[0119] The outer groove wall 1011 is gradually expanded outward along the first direction Z, which means that in the first direction Z, the outer groove wall 1011 is gradually expanded in the direction away from the splicing body 112, that is, through the extension of the outer groove wall 1011 of the limiting groove 101, the limiting groove 101 is gradually expanded outward along the first direction Z. It can be understood that whether the outer groove wall 1011 of the limiting groove 101 is gradually contracted or gradually expanded depends mainly on whether the limiting groove 101 is gradually contracted or gradually expanded under the extension of the outer groove wall 1011. It can be understood that the outer groove wall 1011 can be the inner circumferential wall of the first limiting ring 104. Under the extension of the outer groove wall 1011, the first limiting ring 104 where the outer groove wall 1011 is located is gradually contracted outward along the first direction Z, that is, the inner circumferential wall of the first limiting ring 104 is gradually contracted outward along the first direction Z. The outer groove wall 1011 is annular, and the surface shape can be an inclined surface, a curved surface, etc.

[0120] The outer peripheral wall of the second limiting ring 121 is adapted to the outer groove wall 1011 in shape, so that in the first direction Z, the outer peripheral wall of the second limiting ring 121 is gradually set in the direction close to the splicing body 112. Similarly, by extending the outer peripheral wall of the second limiting ring 121, the second limiting ring 121 is gradually set in the direction close to the splicing body 112. Among them, the outer peripheral wall of the second limiting ring 121 is annular, and the surface shape is roughly the same as the surface shape of the outer groove wall 1011 of the corresponding limiting groove 101, which can be an inclined surface, a curved surface, etc.

[0121] Such arrangement enables the outer groove wall 1011 of the limiting groove 101 to guide the second limiting ring 121 , so that the second limiting ring 121 can be sleeved on the outer periphery of the first limiting ring 104 , thereby facilitating the limiting member 12 to realize the splicing and fixing operation of multiple splicing members 11 .

[0122] In some embodiments, please refer to Figures 3 to 10 , and in combination with other drawings. The limiting ribs 111 on opposite sides of the splicing piece 11 along the first direction Z are arranged in mirror symmetry.

[0123] The limiting ribs 111 on the opposite sides of the splicing piece 11 along the first direction Z are arranged in a mirror-symmetrical manner, which means that the limiting ribs 111 on the opposite sides of the splicing piece 11 along the first direction Z are arranged in a mirror-symmetrical manner with respect to the axis where the radial direction b is located. It can also be understood that the limiting ribs 111 on the opposite sides of the splicing piece 11 along the first direction Z are arranged symmetrically with respect to the first plane.

[0124] For example, Figure 5 As shown, the plurality of splicing pieces 11 have an auxiliary line L, the auxiliary line L is parallel to the radial direction b, and the limiting ribs 111 on opposite sides of the splicing piece 11 along the first direction Z are symmetrically arranged relative to the auxiliary line L.

[0125] With such arrangement, when the limiting member 12 cooperates with the limiting rib 111 , there is no need to distinguish the front and back sides of the splicing piece 11 , which facilitates the limiting member 12 to realize the splicing and fixing operation of multiple splicing pieces 11 .

[0126] In some embodiments, please refer to Figures 4 to 10 The splicing structure 10 includes two stoppers 12, the first connection parts 122 of the two stoppers 12 are respectively arranged on opposite sides of the splicing piece 11 along the first direction Z, the second stopper rings 121 of the two stoppers 12 are respectively sleeved on the first stopper rings 104 on opposite sides of the splicing piece 11, and the first connection parts 122 of the two stoppers 12 are connected to each other.

[0127] Specifically, among the two limiting members 12, the first connecting portion 122 of one limiting member 12 is arranged on one side of the splicing piece 11 along the first direction Z, and the second limiting ring 121 of the limiting member 12 is sleeved on the outer periphery of the first limiting ring 104 on that side of the splicing piece 11; the first connecting portion 122 of the other limiting member 12 is arranged on the other side of the splicing piece 11 along the first direction Z, and the second limiting ring 121 of the limiting member 12 is sleeved on the outer periphery of the first limiting ring 104 on that side of the splicing piece 11.

[0128] The first connecting portions 122 of the two limiting members 12 are respectively arranged on opposite sides of the splicing piece 11 along the first direction Z and are connected to each other, so that the multiple splicing pieces 11 can be limited between the first connecting portions 122 of the two limiting members 12 along the first direction Z, thereby realizing the limitation of the multiple splicing pieces 11 in the first direction Z, so as to realize the splicing and fixation of the multiple splicing pieces 11.

[0129] The first connection portions 122 of the two limiting members 12 may be directly connected or indirectly connected via other intermediate components, and the intermediate component may be, but is not limited to, the second connection portion 123 mentioned below.

[0130] Specifically, the first connection parts 122 of the two stoppers 12 respectively abut against the stopper ribs 111 on the opposite sides of the splicing piece 11 along the first direction Z. Specifically, the first connection part 122 of one stopper 12 abuts against the stopper rib 111 on one side of the splicing piece 11 along the first direction Z, and the first connection part 122 of the other stopper 12 abuts against the stopper rib 111 on the other side of the splicing piece 11 along the first direction Z.

[0131] In some embodiments, please refer to Figures 3 to 10, and in combination with other drawings. A plurality of splicing pieces 11 are arranged to form a through hole 102, and a first limiting ring 104 is arranged around the outer periphery of the through hole 102. The two limiting pieces 12 are respectively a first limiting piece 12a and a second limiting piece 12b, the first limiting piece 12a further comprising a second connecting portion 123 connected to the first connecting portion 122, and the second limiting ring 121 is arranged around the outer periphery of the second connecting portion 123. The second connecting portion 123 is inserted into the through hole 102 along the first direction Z to be connected to the first connecting portion 122 of the second limiting piece 12b.

[0132] Specifically, the second connection portion 123 extends out from a side of the first connection portion 122 having the second limiting ring 121 , and the second limiting ring 121 is disposed around the outer circumference of the second connection portion 123 .

[0133] Specifically, the first connection portion 122 of the first limiter 12a abuts against the limit rib 111 on one side of the splicing piece 11 along the first direction Z, and the second limit ring 121 of the first limiter 12a is sleeved on the first limit ring 104 on the side of the splicing piece 11 along the first direction Z. The first connection portion 122 of the second limiter 12b abuts against the limit rib 111 on the other side of the splicing piece 11 along the first direction Z, and the second limit ring 121 of the second limiter 12b is sleeved on the first limit ring 104 on the side of the splicing piece 11 along the first direction Z. The second connection portion 123 of the first limiter 12a is disposed in the through hole 102 along the first direction Z, and is connected to the first connection portion 122 of the second limiter 12b.

[0134] In this way, the plurality of splicing pieces 11 can be limited along the first direction Z between the first connection portion 122 of the first limiting piece 12a and the first connection portion 122 of the second limiting piece 12b, and the first connection portion 122 of the first limiting piece 12a and the first connection portion 122 of the second limiting piece 12b are connected through the second connection portion 123, so that the plurality of splicing pieces 11 can be limited in the first direction Z. In addition, each second limiting ring 121 can be sleeved on the outer circumference of each first limiting ring 104 to limit the plurality of splicing pieces 11 in the radial direction b. In this way, the splicing and fixing effect of the plurality of splicing pieces 11 is achieved.

[0135] In some embodiments, see Figure 3 , and in combination with other drawings. The second connection portion 123 is threadedly connected to the first connection portion 122 of the second stopper 12b.

[0136] As an example, the first connection portion 122 of the second stopper 12b is provided with an assembly hole 103, the second stopper ring 121 of the second stopper 12b is arranged around the outer periphery of the assembly hole 103, and an internal thread is arranged in the assembly hole 103. The outer peripheral wall of the second connection portion 123 is provided with an external thread, so that the second connection portion 123 is threadedly connected to the assembly hole 103 to achieve a threaded connection between the second connection portion 123 and the first connection portion 122 of the second stopper 12b.

[0137] The threaded connection facilitates the connection between the first limiting member 12a and the second limiting member 12b, thereby facilitating the sleeve connection of each second limiting ring 121 on the outer periphery of each first limiting ring 104, so as to facilitate the splicing and fixing operation of multiple splicing pieces 11.

[0138] In some embodiments, please refer to Figures 2 to 11 , and combined with other drawings. Among them, Fig.11 The three-dimensional structure diagram of the first stopper 12a of the splicing structure 10 provided in some other embodiments of the present application. The through hole 102 is a non-circular hole, and the second connecting portion 123 is adapted to the through hole 102 to form a stopper along the circumferential direction a.

[0139] The second connection portion 123 and the through hole 102 are adapted to each other, which means that the cross-sectional shape of the portion of the second connection portion 123 that is used to pass through the through hole 102 and that is perpendicular to the first direction Z is adapted to the shape of the through hole 102 .

[0140] As an example, Figure 2 , Figure 4 and Fig.11 As shown, the through hole 102 is roughly square, and at least part of the second connection portion 123 is square in cross section perpendicular to the first direction Z, so that the second connection portion 123 and the through hole 102 are adapted. In this way, the second connection portion 123 can be limited in the through hole 102 along the circumferential direction a. The through hole 102 can also be non-circular, such as elliptical, prismatic, etc.

[0141] It should be noted that, when the first stopper 12a does not need to rotate relative to the splicing piece 11, the second connection portion 123 of the first stopper 12a can be configured to fit the through hole 102. For example, when the second connection portion 123 of the first stopper 12a and the first connection portion 122 of the second stopper 12b are threadedly connected, the second stopper 12b can be rotated, so that the second connection portion 123 and the first connection portion 122 of the second stopper 12b can be threadedly connected.

[0142] It should also be noted that, when both the first limiting member 12 a and the second limiting member 12 b need to rotate relative to the splicing member 11 , the second connecting portion 123 may not be configured to match the shape of the through hole 102 .

[0143] See also Fig.12 , and in combination with other drawings, the frame 100 provided in the embodiment of the present application includes two first side beams 20, two second side beams 30 and four splicing structures 10. Among them, the splicing structure 10 in this embodiment is the same as the splicing structure 10 in the above embodiments. For details, please refer to the relevant description of the splicing structure 10 in the above embodiments, which will not be repeated here.

[0144] The two first side beams 20 are spaced apart along the second direction X, and the two second side beams 30 are spaced apart along the third direction Y. The four splicing structures 10 are respectively disposed at opposite ends of the two first side beams 20, and two splicing pieces 11 of the splicing structures 10 are respectively connected to the first side beam 20 and the second side beam 30.

[0145] It can be understood that, of the two opposite ends of one of the first side beams 20, one end is connected to one end of one of the second side beams 30, and the other end is connected to one end of another second side beam 30. Of the two opposite ends of another first side beam 20, one end is connected to the other end of one of the second side beams 30, and the other end is connected to the other end of another second side beam 30. The above connection refers to indirect connection through the splicing structure 10. Specifically, among the four splicing structures 10, two splicing structures 10 are arranged at the opposite ends of one of the first side beams 20 in a one-to-one correspondence, and the other two splicing structures 10 are arranged at the opposite ends of another first side beam 20 in a one-to-one correspondence.

[0146] It can be understood that two of the splicing pieces 11 of each splicing structure 10 are respectively connected to the first side beam 20 and the second side beam 30 to achieve an indirect connection between the first side beam 20 and the second side beam 30 .

[0147] It can be understood that the two first side beams 20 and the two second side beams 30 are arranged in a crisscross manner so that the frame 100 is roughly square, and the two first side beams 20 and the two second side beams 30 are the four sides of the square structure.

[0148] Among them, the first direction Z and the second direction X intersect, the second direction X and the third direction Y intersect, and the first direction Z and the third direction Y intersect. The first direction Z and the second direction X intersect, which means that the first direction Z and the second direction X can form an angle greater than 0° and less than 180°, that is, the first direction Z and the second direction X are not parallel. The first direction Z and the second direction X can be perpendicular to each other, or they can be non-perpendicular. The first direction Z and the second direction X can be directions that intersect on the same plane, or they can be directions on planes that are not in the same plane, and the projection of the second direction X on the plane where the first direction Z is located can intersect with the first direction Z. Correspondingly, the meanings of the first direction Z and the third direction Y intersecting, and the second direction X and the third direction Y intersecting can also be explained in the same way, and will not be repeated here. As an example, the first direction Z and the second direction X are perpendicular, the first direction Z and the third direction Y are perpendicular, and the second direction X and the third direction Y are perpendicular.

[0149] The first direction Z, the second direction X, the third direction Y, the circumferential direction a and the radial direction b are all double-arrow directions.

[0150] The frame 100 provided in the embodiment of the present application may be a photo frame, or may be a frame 100 of a cabinet, etc.

[0151] The frame 100 provided in the embodiment of the present application adopts the splicing structure 10 involved in the above embodiments, so that the first side beam 20 and the second side beam 30 are connected through the splicing structure 10, that is, the limiting member 12 of the splicing structure 10 can realize the splicing and fixing of the first side beam 20 and the second side beam 30, which helps to simplify the fixing operation of the first side beam 20 and the second side beam 30 and improve the splicing and fixing efficiency of the first side beam 20 and the second side beam 30, that is, improve the molding efficiency of the frame 100.

[0152] The splicing piece 11 and the first side beam 20 , and the splicing piece 11 and the second side beam 30 may be integrally formed, or may be separately connected by welding, bolt fixing, or the like.

[0153] It should be noted that the splicing structure 10 may include two splicing pieces 11, and the two splicing pieces 11 are respectively connected to the first side beam 20 and the second side beam 30. Fig.12 As shown, the splicing structure 10 may also include more than three splicing pieces 11 , for example, four splicing pieces 11 , wherein two splicing pieces 11 are respectively connected to the first side beam 20 and the second side beam 30 , and the remaining splicing pieces 11 are not connected to the first side beam 20 or the second side beam 30 .

[0154] In some embodiments, please refer to Figure 12 to Figure 14 , and combined with other drawings. Among them, Fig.13The three-dimensional structure diagram of the frame structure 1000 provided in some other embodiments of the present application is as follows: Fig.14 for Fig.13 The first side beam 20 and the second side beam 30 are respectively connected to two adjacent splicing pieces 11 along the circumferential direction a.

[0155] Such an arrangement allows the splicing piece 11 for the first side beam 20 and the splicing piece 11 for the second side beam 30 to abut against each other, which can increase the connection strength between the first side beam 20 and the second side beam 30 to improve the structural stability of the frame 100.

[0156] In some embodiments, please refer to Figure 4 , Figure 12 to Figure 14 , and in combination with other drawings. The angles formed by the two opposite side walls of each splicing piece 11 along the circumferential direction a are the same.

[0157] like Figure 4 As shown, the angle formed by the two opposite side walls of the splicing piece 11 along the circumferential direction a is a first angle β.

[0158] The same angles formed by the two opposite side walls of each assembling piece 11 along the circumferential direction a refer to that the first angles β of each assembling piece 11 are set to be the same, that is, the first angles β of any two assembling pieces 11 are the same.

[0159] As an example, Figure 4 As shown, the splicing structure 10 includes four splicing pieces 11 , and the first angle β of each splicing piece 11 is substantially 90°, so that the first angles β of the plurality of splicing pieces 11 are the same.

[0160] Such arrangement enables the plurality of splicing pieces 11 to be evenly distributed along the circumferential direction a, which helps to balance the force and improve the structural stability of the frame 100. It also facilitates the expansion of the frame 100. Specifically, when the number of splicing pieces 11 is greater than two, the splicing pieces 11 that are not connected to the first side beam 20 and the second side beam 30 of the frame 100 can be connected to other side beams to achieve the expansion of the frame 100 on the first plane.

[0161] In some cases, two first side beams 20 and two second side beams 30 may be provided with a panel 2000, so that the frame 100 and the panel 2000 are used in conjunction with each other. The first side beam 20 and the panel 2000, and the second side beam 30 and the panel 2000 may be integrally formed or separately connected.

[0162] See also Fig.12 , and in combination with other drawings, the frame structure 1000 provided in the embodiment of the present application includes a frame 100 and a column 200 , the column 200 is connected to the limiting member 12 and is used to support the frame 100 .

[0163] The column 200 refers to a component used to support the frame 100 .

[0164] The provision of the column 200 enables the frame 100 to be used in conjunction with the column 200 to be used as a table, a stool, a cabinet, or other products.

[0165] The frame 100 in this embodiment is the same as the frame 100 in the above embodiments. Please refer to the relevant description of the frame 100 in the above embodiments for details, which will not be repeated here.

[0166] The frame structure 1000 provided in the embodiment of the present application helps to improve the molding efficiency of the frame structure 1000 by adopting the frame 100 involved in the above embodiments.

[0167] In some embodiments, please refer to Fig.13 and Fig.14 , and in combination with other drawings. The frame structure 1000 includes a plurality of frames 100, at least some of which are distributed along the second direction X. Two adjacent frames 100 along the second direction X share a first side beam 20, which is a first common beam 20a. The first common beam 20a and two adjacent second side beams 30 are respectively connected to three splicing pieces 11 of the splicing structure 10.

[0168] For ease of description, two frames 100 adjacent to each other along the second direction X are defined as a first frame 100a and a second frame 100b. It can be understood that the first frame 100a is integrally formed with the first side beam 20 close to the second frame 100b, and the second frame 100b is integrally formed with the first side beam 20 close to the first frame 100a, forming a first side beam 20 shared by the first frame 100a and the second frame 100b, which is a first common beam 20a. Correspondingly, the splicing structures 10 at opposite ends of the first common beam 20a are also shared by the two frames 100.

[0169] Specifically, the splicing structure 10 includes more than three splicing pieces 11. In the splicing structures 10 at opposite ends of the first common beam 20a, the three splicing pieces 11 of any one of the splicing structures 10 are respectively connected to the first common beam 20a, one of the second side beams 30 of the first frame 100a, and one of the second side beams 30 of the second frame 100b, so that the first common beam 20a and two adjacent second side beams 30 are respectively connected to three splicing pieces 11 of the splicing structure 10.

[0170] It can be understood that the splicing structure 10 of the frame 100 includes more than three splicing pieces 11, wherein the three splicing pieces 11 can be connected to a first side beam 20 and two adjacent second side beams 30, so that the frame 100 can be expanded in the second direction X, and the first side beam 20 and the splicing structure 10 can be shared between two adjacent frames 100 along the second direction X.

[0171] Such arrangement realizes the expansion of the frame 100 in the second direction X. Moreover, three splicing pieces 11 of the splicing structure 10 are respectively connected to a first side beam 20 and two adjacent second side beams 30, so that the expansion of the frame 100 in the second direction X can be realized, and the expansion of the frame 100 in the second direction X is very simple, convenient and efficient.

[0172] In some embodiments, please refer to Fig.15 and Fig.16 , and combined with other drawings. Among them, Fig.15 The three-dimensional structure diagram of the frame structure 1000 provided in some embodiments of the present application is as follows: Fig.16 for Fig.15 The enlarged view of the point F in the middle. At least part of the frame 100 is distributed along the third direction Y. Two adjacent frames 100 along the third direction Y share a second side beam 30, which is a second common beam 30a. The second common beam 30a and the two adjacent first side beams 20 are respectively connected to three splicing pieces 11 of the splicing structure 10.

[0173] For ease of description, two adjacent frames 100 along the third direction Y are defined as a first frame 100a and a third frame 100c. It can be understood that the first frame 100a is integrally formed with the second side beam 30 close to the third frame 100c, and the third frame 100c is integrally formed with the second side beam 30 close to the first frame 100a, forming a second side beam 30, which is shared by the first frame 100a and the third frame 100c, and is a second common beam 30a. Correspondingly, the splicing structures 10 at the opposite ends of the second common beam 30a are also shared by the two frames 100.

[0174] Specifically, the splicing structure 10 includes more than three splicing pieces 11. In the splicing structures 10 at opposite ends of the second common beam 30a, the three splicing pieces 11 of any one of the splicing structures 10 are respectively connected to the second common beam 30a, one of the first side beams 20 of the first frame 100a, and one of the first side beams 20 of the third frame 100c, so that the second common beam 30a and two adjacent first side beams 20 are respectively connected to three splicing pieces 11 of the splicing structure 10.

[0175] It can be understood that the splicing structure 10 of the frame 100 includes more than three splicing pieces 11, wherein the three splicing pieces 11 can be connected to a second side beam 30 and two adjacent first side beams 20, so that the frame 100 can be expanded in the third direction Y, and the second side beam 30 and the splicing structure 10 can be shared between two adjacent frames 100 along the third direction Y.

[0176] Such arrangement realizes the expansion of the frame 100 in the third direction Y.

[0177] It should be noted here that the splicing structure 10 may include more than four splicing pieces 11, wherein three splicing pieces 11 may be respectively connected to a second side beam 30 and two adjacent first side beams 20 to achieve expansion of the frame 100 in the third direction Y, and the remaining splicing piece 11 structure is connected to the first common beam 20a to achieve expansion of the frame 100 in the second direction X.

[0179] For the convenience of description, two adjacent frames 100 along the first direction Z are defined as the fourth frame 100d and the fifth frame 100e, respectively. The splicing structure 10 of the fourth frame 100d is provided with a limiting piece 12 on the side close to the fifth frame 100e, and the splicing structure 10 of the fifth frame 100e is provided with a limiting piece 12 on the side close to the fourth frame 100d, and the column 200 is connected to the limiting piece 12 of the fourth frame 100d and the limiting piece 12 of the fifth frame 100e.

[0180] There may be a plurality of upright posts 200 , and all four splicing structures 10 of the frame 100 may be connected to the upright posts 200 , or only some of the splicing structures 10 may be connected to the upright posts 200 .

[0181] Such an arrangement facilitates the combination of the frame 100 in the first direction Z, so that the frame structure 1000 can be roughly cubic, which is convenient for forming a cabinet.

The splicing structure 10 includes two limit members 12, and limit ribs 111 are provided on opposite sides of the splicing member 11 along the first direction Z. The two limit members 12 cooperate with the limit ribs 111 on opposite sides of the splicing member 11. Both limit members 12 of the splicing structure 10 are connected to the columns 200.

[0183] Such an arrangement facilitates the combination of more than three frames 100 in the first direction Z.

[0184] In some embodiments, see Fig.17 , and in combination with other drawings. The frame structure 1000 includes more than three frames 100 spaced apart along a first direction Z, and a column 200 is connected between any two adjacent frames 100 along the first direction Z.

[0185] Such an arrangement enables more than three frames 100 to be combined in the first direction Z through the pillars 200 , so that a plurality of cubic combination structures can be combined in the first direction Z.
