Because the detachable assembled frame structure can be disassembled and reused, and is easy to transport.

From the construction of small shelves or stages to the construction of large venues and buildings, the detachable assembled frame structure can be used.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0056] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as they do not conflict with each other.

[0058] The utility model provides Figure 4 , Figure 5 and Figure 6 As shown, a barrel-in-barrel nut integrated component and a modular structural frame can be used to assemble multi-channel pipe connectors, and then can match other structural parts in the frame structure to achieve a flexible splicing effect. Its main structure includes: a barrel-in-barrel nut integrated component body 4, the barrel-in-barrel nut integrated component body 4 is a square tube structure, and the square tube structure is symmetrically provided with extended screw holes 61 around, and at least two sides of the square tube structure are detachably connected to the bracket-type component 3 through the extended screw holes 61;

[0059] A connecting channel is provided at one end of the corbel-type component 3 away from the body 4 of the barrel-in-barrel nut integrated component, and the body 4 of the barrel-in-barrel nut integrated component and the corbel-type component 3 form a multi-channel pipe connector.

[0060] It should be noted that today's assembled frame structures are usually developed for specific fields. When it is necessary to disassemble and modify the layout of the frame structure, the renovation is difficult and the flexibility is low. It is not conducive to green environmental protection and resource recycling. This solution adopts a modular design, standardized barrel-in-barrel nut integrated component body 4 and bullnose components 3, high component assembly flexibility, bolts and hole standards, and consumers can assemble them into pipe connectors of different channels according to their needs to adapt to the pipe section connection of the overall structural frame. For example, the barrel-in-barrel nut integrated component body 4 is connected with bullnose components 3 on all sides to form a cross-shaped four-channel pipe connector. Then the other structural parts in the structural frame are connected through four bullnose components 3.

[0061] Further, such as Figure 4 As shown, a bottom plate 31 is provided on one end of the corbel-type component 3 near the barrel-in-barrel nut integrated component body 4, and a plurality of screw holes 6 for screwing the extended screw holes 61 are provided on the bottom plate 31. The bottom plate 31 is integrally formed with the corbel-type component 3. The screw holes 6 on the bottom plate 31 match the extended screw holes 61. The extended screw holes 61 on other components in the entire structural frame are configured to be consistent. In this way, the corbel-type component 3 can adapt to the extended screw holes 61 on other components in the structural frame, and flexible splicing of pipe fittings is achieved.

[0062] The second aspect provides Figures 1 to 3 , Figures 7 to 23A modular structural frame shown can be used to build billboard frame structures, shelves, building frame structures, stages and other frame structures. It includes: a number of tube-in-tube straight-through connection members 2, a number of tube-in-tube nut integrated members as described in any one of the first aspects, a number of straight-through pipe assemblies 1 and a number of first right-angle connection members 5, a number of screw holes 6 are provided on the side walls at both ends of the tube-in-tube straight-through connection member 2; a number of screw holes 6 for screwing the tube-in-tube straight-through connection member 2 are opened at one end of the corbel-type member 3 away from the bottom plate 31; a number of screw holes 6 for screwing the corbel-type member 3 and the tube-in-tube straight-through connection member 2 are provided on the end side wall of the straight-through pipe assembly 1; the first right-angle connection member 5 includes two mutually perpendicular connection ends 51, and the connection ends 51 are provided with a number of screw holes 6 for screwing the tube-in-tube straight-through connection member 2. Among them, the two connection ends 51 on the first right-angle connection member 5 are preferably connected by laser welding. As Fig.13 As shown in B.

[0063] It should be noted that today's assembled frame structures are usually developed for specific fields. When it is necessary to dismantle and modify the frame structure layout, the old renovation is difficult and the flexibility is low. It is not conducive to green environmental protection and resource recycling. This solution adopts a modular design, standardized components, components with high assembly flexibility, and universal bolt and hole standards. It can be assembled into different frame structures according to consumer needs, or beams can be added to the main weighing positions on the original basis to enhance the structural strength. (such as Figure 8 , Fig. 9 and Fig.10 It is easy to assemble, disassemble and carry, and can be used across borders and recycled. It greatly reduces the investment in financial, material and human resources.

[0064] Specifically, Fig. 9 and Fig.10As shown, the connection between the straight-through pipe assembly 1 and the straight-through pipe assembly 1, and between the straight-through pipe assembly 1 and the first right-angle connection member 5, both require the tube-in-tube straight-through connection member 2 as a connecting beam to complete the splicing. Take the splicing between the straight-through pipe assembly 1 and the straight-through pipe assembly 1 as an example: half of the tube-in-tube straight-through connection member 2 is inserted into the end of the first straight-through pipe assembly 1, and the two are screwed and fixed through the screw hole 6; the other half of the tube-in-tube straight-through connection member 2 is inserted into the end of the second straight-through pipe assembly 1, and the two are also screwed and fixed through the screw hole 6. At this point, the splicing of the two straight-through pipe assemblies 1 is achieved, and because the spacing and size of the screw holes 6 are calibrated to be consistent, the splicing of the two straight-through pipe assemblies 1 can be flat and fit, so that the joints of the structural components are flatter, the formed frame structure is more beautiful, and the structural strength of the splicing is higher. It should be noted that the connecting ends of the straight-through pipe assembly 1 and the first right-angle connecting member 55 are matched with the tube-in-tube straight-through connecting member 2 and the corbel-type member 3, and the hole spacing, punching position and size of the screw holes 6 are also consistent, so that the splicing surface between the structural members is smoother, and the plug-in connection method makes the structural strength of the splicing between the structural members higher.

[0065] Further, such as Figure 8 As shown, the middle side wall of the through-connection member is also provided with a plurality of extended screw holes 61 for screwing the bottom plate 31. It can be understood that the extended screw holes 61 on the side wall in this embodiment can be spliced ​​with the corbel type member 3, and then the T-shaped structural components can be spliced ​​through the corbel type member 3, so that more styles of structural frames can be assembled.

[0066] In specific implementation, one end of the tube-in-tube straight-through connection member 2 is plugged into the through hole 01 of the straight-through pipe assembly 1, and the other end of the tube-in-tube straight-through connection member 2 is plugged into other structural components, such as the screw-connected corbel-type component 3, and is screwed and fixed through the screw hole 6. Therefore, in order to improve the flexibility of splicing structural components, the corbel-type component 3, the first right-angle connection component 5, the second right-angle connection component 11 and other splicing components need to be provided with through holes 01 of the same size and shape, so that the structural components can be flexibly spliced.

[0067] Further, such as Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, the straight-through pipe assembly 1 is provided with a through hole 01 along its extension direction, and the through hole 01 is used to sleeve the barrel-in-barrel nut integrated component body 4, the bull leg component 3 and the barrel-in-barrel straight-through connecting component 2, and the barrel-in-barrel nut integrated component body 4, the bull leg component 3 and the barrel-in-barrel straight-through connecting component 2 are all matched and connected with the through hole 01;

[0068] A plurality of extended screw holes 61 are disposed on the middle side wall of the straight-through pipe assembly 1 , and the straight-through pipe assembly 1 is connected to the bottom plate 31 via the extended screw holes 61 .

[0069] In this embodiment, a plurality of extended screw holes 61 for screwing the bottom plate 31 are also provided on the middle side wall of the straight pipe assembly 1. The side wall of the straight pipe assembly 1 can be spliced ​​with the bracket-type component 3, and then the T-shaped structural components can be spliced ​​through the bracket-type component 3, so that more styles of structural frames can be assembled.

[0070] Among them, Fig.11 and Fig.12 As shown, when the corbel-type component 3 is spliced ​​on the middle side wall of the straight-through pipe assembly 1, in order to increase the structural strength between the two, a barrel-in-barrel nut integrated component body 4 is added at the position corresponding to the extended screw connection hole 61 inside the through hole 01 of the straight-through pipe assembly 1, so that the extended screw connection holes 61 of the barrel-in-barrel nut integrated component body 4, the straight-through pipe assembly 1 and the corbel-type component 3 correspond to each other, and then the three are screwed and fastened by long bolts. In this way, the three sides are closely attached, and the structural strength of the connection surface is greater.

[0071] Further, such as Fig.16 As shown, at least one panel 8 is detachably connected to the straight-through pipe assembly 1; at least one hanger 81 is screwed on the panel 8, and the hanger 81 is provided with a plurality of screw holes 6 for screwing the straight-through pipe assembly 1; a mounting hole 811 is provided on the side wall of the straight-through pipe assembly 1, and the mounting hole 811 is used for screwing the screw holes 6 on the hanger 81; the panel 8 is detachably connected to the straight-through pipe assembly 1 through the hanger 81;

[0072] Among them, a bending portion 82 is provided on one end of the hanger 81 for connecting the straight-through pipe assembly 1, and the bending portion 82 surrounds a limiting groove 83, which is used to clamp the straight-through pipe assembly 1, and the limiting groove 83 matches the outer wall of the straight-through pipe assembly 1.

[0073] It should be noted that a plurality of stacked panels 8 can increase the structural strength of the overall panel 8. Advertisements can be printed on the panel 8, and the left and right sides can serve as partitions. Various decorative panels 8 can be mounted on the keel frame and the rack, and can be widely used in interior and exterior decoration, commercial street door plaques, exhibition stands and racks for large exhibitions, modern modular furniture or fashionable temporary construction sheds and other fields.

[0074] When disassembly and transportation are required, the panels 8 can be spliced ​​together to form a storage box through the hanger 81, and then assembled into a standard, convenient and durable logistics box to store the remaining pipes and components.

[0075] When assembling the panel 8, the panel 8 can be hung on the straight pipe assembly 1 through the bent portion 82, so that the staff can easily align and screw the screw holes 6. The panel 8 is hung on the straight pipe assembly 1 through the hanger 81, replacing the traditional connection method of gluing or nailing. It is convenient to disassemble and recycle the structural frame, and the connection strength between the panel 8 and the straight pipe assembly 1 can be improved.

[0076] Further, such as Fig.19 As shown, at least one wall connector 9 is detachably connected to the straight-through pipe assembly 1, and the wall connector 9 is provided with a plurality of screw holes 6 for connecting the straight-through pipe assembly 1. It can be understood that the assembled frame structure can be further mounted and fixed to the wall through the wall connector 9, thereby improving the firmness and stability of the frame structure.

[0077] Further, such as Fig.14 As shown, at least one second right-angle connection member 11 is detachably connected to the straight-through pipe assembly 1, and the second right-angle connection member 11 at least includes a first bolting end 111, a second bolting end 112, and a third bolting end 113, one end of the first bolting end 111, the second bolting end 112, and the third bolting end 113 are vertically connected to each other, and the first bolting end 111, the second bolting end 112, and the third bolting end 113 are all provided with a plurality of screw holes 6 for screwing the barrel-in-barrel straight-through connection member 2. Among them, the first bolting end 111, the second bolting end 112, and the third bolting end 113 are preferably connected by laser welding.

[0078] Further, such as Fig.15 As shown, at least one third right-angle connecting member 7 is detachably connected to the straight-through pipe assembly 1, and the third right-angle connecting member 7 at least includes a fourth bolting end 71 and a straight-through bolt tube 72, and the fourth bolting end 71 is vertically connected to the middle of the straight-through bolt tube 72, and both ends of the straight-through bolt tube 72 and the end of the fourth bolting end 71 away from the straight-through bolt tube 72 are provided with screw holes 6 for screwing the barrel-in-barrel straight-through connecting member 2.

[0079] The fourth bolt connection end 71 and the straight bolt connection pipe 72 are preferably connected by laser welding.

[0080] Furthermore, at least one right-angle reinforcement member 10 is detachably connected to the straight-through pipe assembly 1, and the right-angle reinforcement member 10 includes a first fixing plate 101, a second fixing plate 102, and a third fixing plate 103, and the first fixing plate 101, the second fixing plate 102, and the third fixing plate 103 are surrounded to form a triangular frame structure;

[0081] Among them, the first fixing plate 101 is perpendicular to the second fixing plate 102, and the first fixing plate 101 and the second fixing plate 102 are both provided with screw holes 6 for screwing the straight-through pipe assembly 1, the tube-in-tube straight-through connecting member 2, the corbel-type member 3, the first right-angle connecting member 5, the second right-angle connecting member 11 and the third right-angle connecting member 7.

[0082] It can be understood that the right-angle reinforcement member 10 is assembled and fixed at the right angle position of the assembled structure to increase the strength of the assembled structure, and can further improve the structural strength of the joints between the structural components. The screw holes 6 on the right-angle reinforcement member 10 match the screw holes 6 of the straight-through pipe assembly 1, the tube-in-tube straight-through connection member 2, the bracket member 3, the first right-angle connection member 5, the second right-angle connection member 11 and the third right-angle connection member 7. The flexibility of assembly between the structural components is improved.

[0083] It should be noted that, as shown in the figure, the above-mentioned tube-in-tube straight-through connecting member 2, straight-through pipe assembly 1, first right-angle connecting member 5, second right-angle connecting member 11, third right-angle connecting member 7 and corbel-type member 3 can be made of round tubes in addition to square tubes.

[0084] like Fig.24 As shown, in some embodiments, notches are provided at both ends of the straight-through pipe assembly 1, and the notches are used to avoid other structural parts during installation so that the straight-through pipe assembly 1 can be smoothly installed into the frame structure.

[0085] like Fig.25 As shown, in some embodiments, the tube-in-tube straight-through connection component 2 is provided with layered screw holes 6, through which the straight-through pipe assembly 1 can be screwed to the corresponding screw holes 6 according to the required length, thereby achieving the effect of adjusting the length.

[0086] It is understandable that there are many openings and screw holes 6 in the modular structure frame, and after the frame structure is assembled as a whole, there will still be many pipe openings and screw holes 6. Fig.26 As shown, in this solution, corresponding plugging members are used to plug these extra openings and screw holes 6. The plugging member is configured as an elastic rubber material structure, which can be better installed.
