The existing decorative lines are glued, with barbs on the back of the decorative lines, and grooves are milled on the front of the wooden shelves. The decorative lines are glued in the grooves to install. However, the grooves are milled on the front of the shelves, and the barbs on both ends of the decorative lines are partially milled flat, which can easily lead to low processing efficiency; if too much glue is applied in the shelf groove, it will overflow, increasing the cleaning work and affecting efficiency; the decorative lines are installed in the shelf groove, and they need to be fixed with paper tape before the glue solidifies, and they need to be left to stand and can only be transported after the glue solidifies. The curing time of the glue also increases the processing cycle; when the parts are installed with glue, they cannot be disassembled and partially replaced when they are damaged, and can only be scrapped as a whole, wasting costs.

[0003] In the existing furniture assembly process, in order to avoid gluing, some assembly structures for decorative strips are also designed.

The plurality of grooves 30AK are arranged in sequence along the length extension direction X of the expansion sleeve 30A. The depth D1 of the grooves 30AK is less than the thickness D0 of the expansion sleeve 30A (it can be understood that the thickness D0 of the expansion sleeve 30A here refers to the wall thickness of the expansion sleeve 30A);

[0055] Along the length extension direction X of the expansion sleeve 30A, the expansion sleeve 30A includes an integrally formed main section 30A1 and a clamping section 30A2, the main section 30A1 is a hollow cylindrical cavity structure, and the clamping section 30A2 is a hollow conical cavity structure; along the direction from the main section 30A1 to the clamping section 30A2, the inner diameter L1 of the clamping section 30A2 gradually decreases;

[0056] The clamping segment 30A2 includes a plurality of side walls 30A20, which surround the periphery of the expansion sleeve 30A and are arranged at intervals; one end of each side wall 30A20 away from the main segment 30A1 includes an outward-turned portion 30A201, and the outward-turned portion 30A201 is folded in a direction away from the cavity structure of the clamping segment 30A2;

[0057] One end of the connecting rod 30B includes a fine thread 30B1, which is sleeved in the nut 30C; the other end of the connecting rod 30B includes a hemispherical end 30B2, which is provided with a locking groove 30B2K; a limiting column 30B3 is included between the fine thread 30B1 and the hemispherical end 30B2 of the connecting rod 30B, which points in the direction of the hemispherical end 30B2 along the fine thread 30B1, and the limiting column 30B3 includes an inserting section 30B31 close to the fine thread 30B1, a tapered section 30B32 close to the hemispherical end 30B2, and a connecting section 30B33 located between the inserting section 30B31 and the tapered section 30B32, and the inserting section 30B31, the connecting section 30B33 and the tapered section 30B32 are integrally formed;

[0058] The connecting section 30B33 is cylindrical, and the plug section 30B31 is frustum-shaped. Along the fine thread 30B1 pointing to the direction of the hemispherical end 30B2, the outer diameter L3 of the plug section 30B31 gradually decreases, and the minimum outer diameter L3 of the plug section min The maximum outer diameter L3 of the plug-in section 30B31 is larger than the outer diameter L2 of the connecting section 30B33. max The inner diameter L01 of the main body section 30A1 is equal to that of the main body section 30A1; the outer diameter L4 of the tapered section 30B32 gradually increases along the direction of the fine pitch thread 30B1 pointing to the hemispherical end 30B2;

[0059] A positioning boss 30B311 is provided on one side of the plug-in section 30B31 close to the fine thread 30B1 , and the positioning boss 30B311 is provided around the periphery of the plug-in section 30B31 .

[0060] Specifically, the decorative strip and board assembly structure 000 provided in this embodiment can be used for mutual assembly and fixation between the metal decorative strip 10 and the wooden board 20 in the furniture assembly process. The board 20 includes a plurality of side surfaces 20A, and the side surfaces 20A of the board 20 can be understood as the side surfaces at the edge of the board 20. If the board 20 is a flat cubic structure, the board 20 can include four side surfaces 20A, such as Figure 1 As shown, the decorative strip 10 is fixedly mounted on at least one side surface 20A of the plate 20 via a plurality of connecting components 30 .

[0061] like Figure 4 and Figure 5 As shown, when the decorative strip 10 is assembled with the plate 20, the side surface 20A of the plate 20 is fixedly connected with the decorative strip 10 through a plurality of connecting components 30. It can be understood that Figure 4 and Figure 5 Only three connection components 30 are shown in the figure. In a specific implementation, a plurality of connection components 30 may be arranged side by side along the length direction M1 of the decorative strip 10 to ensure the assembly stability of the decorative strip 10 and the plate 20 .

[0062] like Figure 3 and Figure 4 As shown, the side of the decorative strip 10 facing the side 20A of the decorative strip 10 includes a T-slot 10K. The T-slot 10K can be opened along the entire length direction M1 of the decorative strip 10. The shape of the T-slot 10K can be understood as a T-shaped structure in a cross section taken along the length direction perpendicular to the decorative strip 10. Along the direction of the decorative strip 10 pointing to the plate 20, the T-slot 10K includes a nut clamping segment 10K1 and a bearing segment 10K2 that penetrate each other. The nut clamping segment 10K1 and the bearing segment 10K2 can both be understood as a hollow structure. The nut clamping segment 10K1 is located on the side of the bearing segment 10K2 close to the plate 20. The inner diameter W1 of the nut clamping segment 10K1 is larger than the inner diameter W2 of the bearing segment 10K2, that is, after the plate 20 is assembled with the decorative strip 10, the nut clamping segment 10K1 of the T-slot 10K is closer to the side 20A of the plate 20 than the bearing segment 10K2.

[0063] like Figure 3 and Figure 6 As shown, the connection assembly 30 includes an expansion sleeve 30A, a connecting rod 30B and a nut 30C, and the nut 30C is embedded in the nut clamping section 10K1 of the T-slot 10K; wherein, the expansion sleeve 30A is used to be embedded in the cylindrical groove 20AK opened on the side 20A of the plate 20, and the connecting rod 30B is used to be screwed into the nut 30C embedded in the nut clamping section 10K1 of the T-slot 10K of the decorative strip 10. In this embodiment, the cylindrical groove 20AK opened on the side 20A of the plate 20 is not described in detail, and the details can be understood by referring to the description of the subsequent embodiments.

[0064] like Figure 7 As shown, a plurality of grooves 30AK are provided on the periphery of the expansion sleeve 30A, and the grooves 30AK are arranged around the expansion sleeve 30A. The plurality of grooves 30AK are arranged in sequence along the length extension direction X of the expansion sleeve 30A, and the depth D1 of the grooves 30AK is less than the thickness D0 of the expansion sleeve 30A (it can be understood that the thickness D0 of the expansion sleeve 30A here refers to the wall thickness of the expansion sleeve 30A). By providing a plurality of grooves 30AK on the periphery of the expansion sleeve 30A, and the grooves 30AK do not penetrate the wall thickness of the expansion sleeve 30A, a rough concave-convex texture can be formed on the periphery of the expansion sleeve 30A, thereby enhancing the friction force when the expansion sleeve 30A is embedded in the columnar groove 20AK provided on the side 20A of the plate 20, thereby improving the stability of the expansion sleeve 30A insertion.

[0065] Along the length extension direction X of the expansion sleeve 30A, the expansion sleeve 30A includes an integrally formed main section 30A1 and a clamping section 30A2, the main section 30A1 is a hollow cylindrical cavity structure, and the clamping section 30A2 is a hollow conical cavity structure. When the part of the connecting rod 30B other than the fine thread 30B1 is inserted into the expansion sleeve 30A, the main section 30A1 is used to accommodate the plug-in section 30B31 at the end of the limiting column 30B3 of the connecting rod 30B, and the clamping section 30A2 is used to accommodate the connecting section 30B33 of the middle part of the limiting column 30B3 of the connecting rod 30B, and the connecting rod 30B is inserted into the expansion sleeve 30A. The conical section 30B32 at the other end of the limiting column 30B3 of 0B and the hemispherical end 30B2 of the connecting rod 30B can extend from the locking segment 30A2. Since the inner diameter L1 of the locking segment 30A2 gradually decreases along the direction of the main section 30A1 pointing to the locking segment 30A2, it is equivalent to that the expansion sleeve 30A is a secondary expansion structure. The space of the locking segment 30A2 is smaller than the space of the main section 30A1. Therefore, after the hemispherical end 30B2 of the connecting rod 30B extends out of the locking segment 30A2, it can be just stuck, so that the connecting rod 30B and the expansion sleeve 30A are firmly clamped in the cylindrical groove 20AK.

[0066] like Figure 7 and Fig. 9 As shown, Fig. 9 yes Figure 7 A schematic diagram of a three-dimensional structure of an expansion sleeve in the middle, the locking segment 30A2 includes a plurality of side walls 30A20, and the plurality of side walls 30A20 surround the periphery of the expansion sleeve 30A and are arranged at intervals. It can be understood that the locking segment 30A2 can be divided into a plurality of (such as 4 or 6) side walls 30A20, and the plurality of side walls 30A20 are arranged around, and a certain gap is left between two adjacent side walls 30A20 to ensure that when the hemispherical end 30B2 of the connecting rod 30B extends out of the locking segment 30A2, the plurality of side walls 30A20 can be opened, and after the hemispherical end 30B2 of the connecting rod 30B extends out of the locking segment 30A2, the plurality of side walls 30A20 can retract by their own elastic force to clamp the hemispherical end 30B2 outside the locking segment 30A2. The end of each side wall 30A20 away from the main section 30A1 includes an outward-turned portion 30A201, which is folded in the direction of the cavity structure away from the clamping segment 30A2. The outward-turned portion 30A201 is used to enable each side wall 30A20 to continue to move in the direction of the cavity structure away from the clamping segment 30A2 when the hemispherical end 30B2 of the connecting rod 30B extends out of the clamping segment 30A2, so as to facilitate the clamping segment 30A2 of the expansion sleeve 30A to be stretched open by the hemispherical end 30B2 of the connecting rod 30B, so that the hemispherical end 30B2 of the connecting rod 30B can more easily pass through the narrow clamping segment 30A2 of the expansion sleeve 30A.

[0067] Optionally, in the present embodiment, the outer diameter of the main section 30A1 of the expansion sleeve 30A may be slightly larger than the inner diameter of the cylindrical groove 20AK. For example, the outer diameter of the main section 30A1 is 0.5 mm larger than the inner diameter of the cylindrical groove 20AK. When the expansion sleeve 30A is inserted into the cylindrical groove 20AK, the expansion sleeve 30A may be interference filled in the cylindrical groove 20AK, thereby further ensuring the fixing effect of the expansion sleeve 30A in the cylindrical groove 20AK.

[0068] like Figure 3 , Figure 6 and Figure 8 As shown, one end of the connecting rod 30B includes a fine thread 30B1, and the fine thread 30B1 is sleeved in the nut 30C. When the decorative strip 10 and the plate 20 are assembled, the nut 30C can be pre-inserted into the nut clamping section 10K1 of the T-slot 10K of the decorative strip 10. The other end of the connecting rod 30B includes a hemispherical end 30B2, and the hemispherical end 30B2 is provided with a locking groove 30B2K. The locking groove 30B2K is used as a fulcrum for tools such as a screwdriver to assist in screwing the fine thread 30B of the connecting rod 30B into the nut 30C pre-inserted in the nut clamping section 10K1 of the T-slot 10K.

[0069] A limiting column 30B3 is included between the fine thread 30B1 and the hemispherical end 30B2 of the connecting rod 30B, and points in the direction of the hemispherical end 30B2 along the fine thread 30B1. The limiting column 30B3 includes an inserting section 30B31 close to the fine thread 30B1, a tapered section 30B32 close to the hemispherical end 30B2, and a connecting section 30B33 located between the inserting section 30B31 and the tapered section 30B32. The inserting section 30B31, the connecting section 30B33 and the tapered section 30B32 are integrally formed. The inserting section 30B31 corresponds to the main section 30A1 of the expansion sleeve 30A, the tapered section 30B32 corresponds to the embedding section 30A2 of the expansion sleeve 30A, and the connecting section 30B33 plays a connecting role. The structure of the integrally formed connecting rod 30B can further ensure the overall assembly firmness. The connecting section 30B33 is cylindrical, and the plug section 30B31 is a circular frustum. Along the fine thread 30B1 pointing to the direction of the hemispherical end 30B2, the outer diameter L3 of the plug section 30B31 gradually decreases, and the minimum outer diameter L3 of the plug section min The maximum outer diameter L3 of the plug-in section 30B31 is larger than the outer diameter L2 of the connecting section 30B33. maxThe inner diameter L01 of the main body section 30A1 is equal to that of the cylindrical connecting section 30B33 and the plug-in section 30B31, which can be better filled in the expansion sleeve 30A, so that the limit column 30B3 of the connecting rod 30B is more tightly embedded in the expansion sleeve 30A. The plug-in section 30B31 is designed to be a cone, and the outer diameter L3 of the plug-in section 30B31 gradually decreases along the direction of the fine thread 30B1 pointing to the hemispherical end 30B2, that is, the outer diameter of the plug-in section 30B31 close to the fine thread 30B1 is large, and the outer diameter of the end away from the fine thread 30B1 is small. The cone-shaped plug-in section 30B31 design can make the connecting rod 30B easier to insert. In this embodiment, the end of the limiting column 30B3 close to the hemispherical end 30B2 is provided with a conical section 30B32, so that after the conical section 30B32 and the hemispherical end 30B2 of the connecting rod 30B extend out from the clamping section 30A2 of the expansion sleeve 30A, part of the conical section 30B32 and the hemispherical end 30B2 are just clamped in the clamping section 30A2, and the connecting rod 30B will not retract. Specifically, along the direction from the fine thread 30B1 to the hemispherical end 30B2, the outer diameter L4 of the tapered section 30B32 gradually increases, that is, the closer to the hemispherical end 30B2, the larger the outer diameter L4 of the tapered section 30B32, and the closer to the hemispherical end 30B2, the thicker the tapered section 30B32. This allows the tapered section 30B32 and the hemispherical end 30B2 of the connecting rod 30B to extend from the locking section 30A2 of the expansion sleeve 30A, so that part of the tapered section 30B32 and the hemispherical end 30B2 are just stuck in the locking section 30A2, and the connecting rod 30B will not retract, so that the connecting rod 30B and the expansion sleeve 30A are firmly plugged into the cylindrical groove 20AK.

[0070] This embodiment also sets the minimum outer diameter L3 of the plug-in section 30B31 min The maximum outer diameter L3 of the plug-in section 30B31 is greater than the outer diameter L2 of the connecting section 30B33, which can prevent the plug-in section 30B31 of the connecting rod 30B from being pushed out of the clamping section 30A2. max The inner diameter L01 of the main body section 30A1 is equal to that of the main body section 30A1, so that after the connecting rod 30B is plugged into the expansion sleeve 30A, the maximum outer diameter L3 of the plug-in section 30B31 max The position can abut against the inner wall of the main section 30A1 of the expansion casing 30A, ensuring the firmness and reliability of the connecting rod 30B after being inserted into the expansion casing 30A.

[0071] like Figure 6 and Figure 8As shown, in the connecting rod 30B of the present embodiment, a positioning boss 30B311 is provided on one side of the plug-in section 30B31 close to the fine thread 30B1, and the positioning boss 30B311 is arranged around the periphery of the plug-in section 30B31. When the connecting rod 30B is inserted into the expansion sleeve 30A, the positioning boss 30B311 can be completely buried in the end of the main section 30A1 of the expansion sleeve 30A, that is, the positioning boss 30B311 can play a good effect of tightly abutting against the inner wall of the main section 30A of the expansion sleeve 30A, which can better ensure the firmness and reliability of the connecting rod 30B after being inserted into the expansion sleeve 30A.

[0072] When the decorative strip and plate assembly structure 000 provided in this embodiment is used, the decorative strip 10 and the plate 20 can be assembled and fixed by using a plurality of connecting components 30. When assembling the decorative strip 10 and the plate 20, as shown in FIG. Figure 4 and Figure 5 As shown, first, a plurality of cylindrical grooves 20AK are formed on the side surface 20A of the plate 20, and then the expansion sleeves 30A are respectively embedded in the cylindrical grooves 20AK of the plate 20. At the same time, a plurality of nuts 30C are pre-embedded in the nut clamping segment 10K1 of the T-slot 10K of the decorative strip 10, and then a screwdriver or other tool is used to apply force to the locking groove 30B2K of the hemispherical end 30B2 of the connecting rod 30B to assist in screwing the fine thread 30B1 of the connecting rod 30B into the nut 30C in the nut clamping segment 10K1 of the T-slot 10K, so that the fine thread 30B1 is sleeved with the nut 30C. Finally, the decorative strip 10 with the connecting rod 30B and the nut 30C and the plate 20 with the expansion sleeve 30A are brought closer together, so that the side of the plate 20 and the decorative strip 10 are closer and closer, and the connecting rod 30B is aligned with the expansion sleeve 30A, and the decorative strip 10 is knocked with a knocking tool such as a rubber hammer, so that the hemispherical end 30B2 of the connecting rod 30B passes through the narrow clamping section 30A2 of the expansion sleeve 30A, and the other parts of the connecting rod 30B except the fine pitch thread 30B are all extended into the expansion sleeve 30A. A, the part of the conical section 30B32 of the limiting column 30B3 of the connecting rod 30B and the hemispherical end 30B2 of the connecting rod 30B finally extend out from the locking section 30A2, and the outward turning portion 30A201 of the side wall 30A20 away from the main section 30A1 can facilitate the locking section 30A2 of the expansion sleeve 30A to be opened by the hemispherical end 30B2 of the connecting rod 30B, so that the hemispherical end 30B2 of the connecting rod 30B can more easily pass through the narrow locking section 30A2 of the expansion sleeve 30A. The positioning boss 30B311 at the end of the plug-in section 30B31 can be pressed against the inner wall of the main section 30A1, and the connecting rod 30B can be firmly plugged into the expansion sleeve 30A without being easily loosened, thereby completing the firm assembly of the decorative strip 10 and the plate 20.

[0073] The present embodiment adopts the structure of the decorative strip 10 and the plate 20 assembled by the connecting component 30. The connecting component 30 has a simple structure, is firm and reliable, and can be completely hidden after assembly. There is no exposed hole on the surface of the plate, and no glue is required. When installing, the connecting rod 30B can be aligned with the expansion sleeve 30A and knocked. The assembly is convenient and quick, and can be completed without consuming a lot of manpower; when disassembling, only a knocking tool such as a rubber hammer is used to knock the plate 20 in the opposite direction (that is, knocking in the direction away from the decorative strip 10) to complete the disassembly of the decorative strip 10 and the plate 20. The disassembly is also convenient and quick, and there is no damage to the plate. Compared with the milling groove on the side surface of the plate in the prior art, the cylindrical groove 20AK in the plate 20 of the present embodiment has a higher processing efficiency, and the decorative strip 10 does not need to mill barbs, install without glue and clean glue marks, which can simplify the process and improve the processing efficiency. The present embodiment adopts the structure of the decorative strip 10 and the plate 20 assembled by the connecting component 30. The damaged parts can be flexibly disassembled and partially replaced and repaired, which is conducive to cost saving.

[0076] This embodiment explains that before the decorative strip 10 and the plate 20 are assembled and fixed through the connecting component 30, a plurality of cylindrical grooves 20AK can be first opened on the side 20A of the plate 20, and the number of connecting rods 30B corresponds to the cylindrical grooves 20AK one by one. The cylindrical grooves 20AK are used to embed the expansion sleeve 30A, and the fine thread 30B1 of the connecting rod 30B is screwed into the nut 30C embedded in the nut embedding section 10K1 of the T-slot 10K of the decorative strip 10 through the locking groove 30B2K. The position of the cylindrical groove 20AK is located, and the connecting rod 30B and the nut 30C are tightened and fixed in position to improve the firmness of the connecting rod 30B and the decorative strip 10. Then, the part of the connecting rod 30B except the fine thread 30B1 is inserted into the expansion sleeve 30A of the cylindrical groove 20AK, which can reduce the difficulty of assembly and improve the assembly efficiency of the plate and the decorative strip 10.

[0082] Among them, Figure 8 , Fig.11 and Fig.12 As shown, the inner diameter W1 of the nut locking segment 10K1 is larger than the outer diameter L0 of the nut 30C, and the inner diameter W2 of the load-bearing segment 10K2 is smaller than the outer diameter L0 of the nut 30C.

[0083] like Figure 4 , Figure 8 , Fig.11 and Fig.12 As shown, the nut clamping section 10K1 of the T-slot 10K includes a limiting opening 10KX on the side facing the plate 20, and the limiting opening 10KX extends along the length direction M1 of the decorative strip 10; the width W3 of the limiting opening 10KX is smaller than the outer diameter L0 of the nut 30C, the width W3 of the limiting opening 10KX is larger than the outer diameter LX of the fine thread 30B1, and the width W3 of the limiting opening 10KX is smaller than the outer diameter LT of the positioning boss 30B311.

[0086] Embodiment 3

[0087] Please refer to Figure 1-Figure 9 , Fig.15 , Fig.15 yes Figure 7 Another three-dimensional structural schematic diagram of the expansion sleeve, an assembly structure 000 of a decorative strip and a plate provided in this embodiment, comprising a decorative strip 10 and a plate 20, the plate 20 comprising a plurality of side surfaces 20A, the decorative strip 10 being fixedly mounted on the side surfaces 20A of the plate 20 through a plurality of connecting components 30;

[0088] The side 20A of the decorative strip 10 facing the plate 20 includes a T-shaped slot 10K. Along the direction of the decorative strip 10 pointing to the plate 20, the T-shaped slot 10K includes a nut clamping segment 10K1 and a bearing segment 10K2 that penetrate each other. The nut clamping segment 10K1 is located on the side of the bearing segment 10K2 close to the plate 20. The inner diameter W1 of the nut clamping segment 10K1 is greater than the inner diameter W2 of the bearing segment 10K2.

[0089] The connection assembly 30 includes an expansion sleeve 30A, a connection rod 30B and a nut 30C. The nut 30C is embedded in a nut embedding section 10K1 of a T-slot 10K.

[0090] The expansion sleeve 30A is formed by bending a steel sheet.

[0091] The locking segment 30A2 of the expansion sleeve 30A includes a plurality of side walls 30A20, which surround the periphery of the expansion sleeve 30A and are arranged at intervals; the end of each side wall 30A20 away from the main segment 30A1 includes an outward-turned portion 30A201, and the outward-turned portion 30A201 is folded in the direction away from the cavity structure of the locking segment 30A2, and the outward-turned portion 30A201 forms an angle α with the side wall 30A20; wherein 90 degrees ≤ α ≤ 150 degrees.

[0092] One end of the main body section 30A1 of the expansion sleeve 30A away from the locking section 30A2 includes an opening 30A1K, and the opening 30A1K extends along the length direction of the expansion sleeve 30A.

[0093] This embodiment explains that the decorative strip 10 and the plate 20 are assembled and fixed by the connecting assembly 30, and the connecting assembly 30 includes an expansion sleeve 30A embedded in the cylindrical groove 20AK of the plate 20, and a connecting rod 30B partially sleeved in the T-slot 10K of the decorative strip 10. The decorative strip 10 and the plate 20 are assembled and fixed by plugging the portion of the connecting rod 30B other than the fine thread 30B1 with the expansion sleeve 30A. The expansion sleeve 30A in the connecting assembly 30 can be formed in one piece by bending a steel sheet, which is conducive to improving the manufacturing efficiency of the expansion sleeve 30A. At the same time, the expansion sleeve 30A made of steel sheet material can make the outer turn 30A201 of the side wall 30A20 away from the end of the main body section 30A1 more elastic and tough. When the expansion sleeve 30A is embedded in the cylindrical groove 20AK of the plate 20, the outer turn 30A201 can facilitate the clamping section 30A2 of the expansion sleeve 30A to be hemispherically connected to the connecting rod 30B. The shaped end portion 30B2 is stretched open, which is conducive to firmly embedding the expansion sleeve 30A in the cylindrical groove 20AK of the plate 20; when the connecting rod 30B is inserted into the expansion sleeve 30A, the insertion section 30B31 of the connecting rod 30B can produce a good interference with the inner wall of the main section 30A1, which is conducive to firmly inserting the part of the connecting rod 30B except the fine thread 30B1 into the expansion sleeve 30A, thereby further improving the reliability of assembling the decorative strip 10 and the plate 20 through the connecting assembly 30.

[0094] The clamping segment 30A2 of the expansion sleeve 30A of this embodiment includes a plurality of side walls 30A20, and each side wall 30A20 includes an outward-turned portion 30A201 at one end away from the main segment 30A1. The angle α formed by the outward-turned portion 30A201 and the side wall 30A20 is in the range of 90 degrees to 150 degrees, which can ensure that after the hemispherical end 30B2 of the connecting rod 30B extends out of the clamping segment 30A2, each side wall 30A20 continues to move in the direction away from the cavity structure of the clamping segment 30A2, so that the clamping segment 30A2 of the expansion sleeve 30A is conveniently opened by the hemispherical end 30B2 of the connecting rod 30B, so that the hemispherical end 30B2 of the connecting rod 30B can more easily pass through the narrow clamping segment 30A2 of the expansion sleeve 30A. Fig.15As shown, the main body section 30A1 of the expansion sleeve 30A of this embodiment includes at least one opening 30A1K at one end away from the locking section 30A2, and the opening 30A1K extends along the length direction of the expansion sleeve 30A. The opening 30A1K can be formed when the expansion sleeve 30A is bent from a steel sheet, so that after the connecting rod 30B is inserted into the expansion sleeve 30A, the main body section 30A1 can be more easily expanded, and the plug-in section 30B31 at the end of the connecting rod 30B can finally abut against the inner wall of the main body section 30A1, so as to prevent the connecting rod 30B from loosening from the expansion sleeve 30A due to the shaking of the plate, thereby improving the assembly stability of the decorative strip 10 and the plate 20.

[0095] Embodiment 4

[0096] Please continue to refer to Figure 1-Figure 9 The present embodiment provides an assembly structure 000 of a decorative strip and a plate, comprising a decorative strip 10 and a plate 20, wherein the plate 20 comprises a plurality of side surfaces 20A, and the decorative strip 10 is fixedly mounted on the side surfaces 20A of the plate 20 through a plurality of connecting components 30;

[0097] The side 20A of the decorative strip 10 facing the plate 20 includes a T-shaped slot 10K. Along the direction of the decorative strip 10 pointing to the plate 20, the T-shaped slot 10K includes a nut clamping segment 10K1 and a bearing segment 10K2 that penetrate each other. The nut clamping segment 10K1 is located on the side of the bearing segment 10K2 close to the plate 20. The inner diameter W1 of the nut clamping segment 10K1 is greater than the inner diameter W2 of the bearing segment 10K2.

[0098] The connection assembly 30 includes an expansion sleeve 30A, a connection rod 30B and a nut 30C. The nut 30C is embedded in the nut clamping section 10K1 of the T-slot 10K. Figure 6-Figure 8 As shown, the maximum outer diameter L4 of the tapered section 30B32 max The minimum outer diameter of the plug-in section 30B31 is larger than the minimum inner diameter of the card segment 30A2 . The minimum outer diameter of the plug-in section 30B31 is larger than the minimum inner diameter of the card segment 30A2 .

[0099] This embodiment explains that the tapered section 30B32 of the connecting rod 30B includes a maximum outer diameter L4 max Since the outer diameter L4 of the tapered section 30B32 gradually increases along the direction of the fine thread 30B1 pointing to the hemispherical end 30B2, the maximum outer diameter L4 of the tapered section 30B32 is max It can be understood as the outer diameter of the position closest to the hemispherical end 30B2, that is, the position where the conical section 30B32 is integrally connected with the hemispherical end 30B2.

[0100] The clamping segment 30A2 of the expansion sleeve 30A includes a minimum inner diameter L1 minSince the inner diameter L1 of the card segment 30A2 gradually decreases along the direction from the main body segment 30A1 to the card segment 30A2, the card segment 30A2 includes the minimum inner diameter L1 min It can be understood as the inner diameter farthest from the plug-in section 30B31, that is, the inner diameter of the bending position between the locking section 30A2 and the side wall 30A20.

[0101] The plug-in section 30B31 is in the shape of a circular frustum. As the fine pitch thread 30B1 points toward the hemispherical end 30B2, the outer diameter of the plug-in section 30B31 gradually decreases. The maximum outer diameter L3 of the plug-in section 30B31 is max It can be understood that the outer diameter of the plug section 30B31 at the position closest to the fine thread 30B1, the minimum outer diameter L3 of the plug section 30B31 min It can be understood as the outer diameter of the plug-in section 30B31 at the position farthest from the fine thread 30B1.

[0102] In this embodiment, the maximum outer diameter L4 of the tapered section 30B32 is set max The minimum inner diameter of the plug-in section 30A2 is larger than that of the plug-in section 30A2, so that the conical section 30B32 of the connecting rod 30B and the hemispherical end 30B2 of the connecting rod 30B can be stuck after extending from the plug-in section 30A2 and are not easy to retract, thereby ensuring that the connecting rod 30B and the expansion sleeve 30A are firmly connected in the cylindrical groove 20AK. min Larger than the minimum inner diameter L1 of the card segment 30A2 min, it can be ensured that after the conical section 30B32 of the connecting rod 30B and the hemispherical end 30B2 of the connecting rod 30B extend out of the clamping section 30A2, the plug-in section 30B31 of the connecting rod 30B will not continue to be pushed out to the outside of the clamping section 30A2, even if the decorative strip 10 is hit with too much force during assembly, the hemispherical end 30B2 of the connecting rod 30B can be prevented from causing additional damage to the plate 20. In addition, in this embodiment, the overall length of the connecting rod 30B excluding the fine pitch thread 30B1 and the overall length of the expansion sleeve 30A need to match each other, that is, the length of the connecting rod 30B excluding the fine pitch thread 30B1 cannot be too long or too short. If the overall length of the connecting rod 30B excluding the fine pitch thread 30B1 is too long, after the connecting rod 30B is inserted into the expansion sleeve 30A, a gap will be formed between the horizontal plate 10 and the side plate 20 connected thereto, affecting the overall stability and aesthetics. In addition, the length of the connecting rod 30B is not too long, which can also prevent the impact of the connecting rod 30B on the horizontal plate 10 caused by the excessive force of hitting the side plate 20. If the overall length of the connecting rod 30B excluding the fine pitch thread 30B1 is too short, the overall firmness of the connecting rod 30B inserted into the expansion sleeve 30A cannot be effectively guaranteed. Therefore, in this embodiment, the overall length of the connecting rod 30B excluding the fine pitch thread 30B1 and the overall length of the expansion sleeve 30A are matched with each other, which is conducive to ensuring the stability and aesthetics of the entire structure.

[0108] The assembly structure of the decorative strip and the plate provided by the utility model can achieve the effect of assembling and fixing the decorative strip and the plate through multiple connecting components. When assembling the decorative strip and the plate, multiple cylindrical grooves are opened on the side of the plate, and then the expansion sleeves are respectively clamped and embedded in the cylindrical grooves of the plate. At the same time, multiple nuts are pre-clamped and embedded in the nut clamping section of the T-slot of the decorative strip, and a tool such as a screwdriver is used to apply force to the locking groove of the hemispherical end of the connecting rod to assist in screwing the fine thread of the connecting rod into the nut in the nut clamping section of the T-slot, so that the fine thread and the nut are sleeved. Finally, bring the decorative strip with the connecting rod and nut and the plate with the expansion sleeve close together, align the connecting rod with the expansion sleeve, and use a rubber hammer or other knocking tool to knock the decorative strip, so that the hemispherical end of the connecting rod can pass through the narrow clamping section of the expansion sleeve, and all the other parts of the connecting rod except the fine thread are inserted into the expansion sleeve. Finally, part of the conical section and the hemispherical end of the connecting rod extend from the clamping section, and the outward-turned part of the side wall away from the end of the main section can facilitate the clamping section of the expansion sleeve to be stretched open by the hemispherical end of the connecting rod, so that the hemispherical end of the connecting rod can pass through the narrow clamping section of the expansion sleeve more easily. The frustum-shaped plug-in section design can make the connecting rod easier to insert. The maximum outer diameter of the plug-in section is equal to the inner diameter of the main section of the expansion sleeve, so that after the connecting rod is plugged into the expansion sleeve, the maximum outer diameter position of the plug-in section can abut against the inner wall of the main section of the expansion sleeve, ensuring the firmness and reliability of the connecting rod after being plugged into the expansion sleeve. The positioning boss at the end of the plug-in section can also be against the inner wall of the main section, and the connecting rod can be firmly inserted into the expansion sleeve without being easily loosened, thereby completing the firm assembly of the decorative strip and the plate. The utility model has a simple structure, is firm and reliable, and can be completely hidden after assembly. There are no exposed holes on the surface of the plate, and no glue is required. When installing, the connecting rod can be aligned with the expansion sleeve and knocked. The assembly is convenient and quick, and it does not require much manpower to complete. When disassembling, it is only necessary to use a rubber hammer or other knocking tools to knock the plate in the opposite direction to complete the disassembly. The disassembly is also convenient and quick, and does not damage the plate. Compared with the prior art of milling grooves on the side surface of the plate, the utility model has a higher processing efficiency of opening a cylindrical groove on the plate, and the decorative strip does not need to be milled with barbs, and does not need to be glued or cleaned up during installation, which can simplify the process and improve processing efficiency. The utility model adopts the structure of the decorative strip and the plate assembled by the connecting assembly. If the parts are damaged, they can be flexibly disassembled and partially replaced and repaired, which is conducive to cost saving.
