Description

Technical Field

[0001] This utility model belongs to the field of modular table technology, specifically relating to a quick-assembly table leg structure and a row of quick-assembly modular tables. Background Technology

[0002] Modular tables are widely used in office meetings, catering and entertainment, exhibitions and other fields due to their modular design, high layout flexibility and structural stability. To facilitate transportation and storage, existing modular tables usually adopt a split design, which is divided into independent modules such as tabletop, table legs, and support frame. After being transported to the installation site, they are assembled on-site using connectors.

[0003] Common connection methods for modular tables are bolt / nut mechanical connection and snap-fit ​​connection. While bolt / nut mechanical connection can ensure high structural strength and load-bearing capacity, it has the disadvantages of high assembly complexity, long installation time, easy loss of parts, and high maintenance costs. Snap-fit ​​connection has weak load-bearing capacity, and repeated disassembly can lead to loosening due to wear of the clips. It also has poor adaptability, high requirements for processing precision, and if there are dimensional deviations between modules, it can lead to assembly difficulties or structural instability. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-assembly table leg structure and a row of quick-assembly combination tables, which overcomes the defects of high assembly complexity and long installation time of existing technologies using bolt / nut mechanical connections, while not requiring high precision in module processing and having strong adaptability, and avoiding the loosening problem caused by wear of the slots after repeated disassembly.

[0006] Specifically, the wedge-shaped quick-release component includes a wedge-shaped block fixedly installed on one side of the table leg and an inclined plate fixedly disposed on the inclined surface of the wedge-shaped block; the edge of the inclined plate protrudes from the outer periphery of the wedge-shaped block; The lower end of the inclined plate is inclined toward the corresponding table leg, and the inclination direction of the mating surface of the n-shaped mating plate is consistent with the inclination direction of the inclined plate.

[0007] Specifically, the through hole includes a first through space for the wedge block to pass through and a second through space for the inclined plate to pass through.

[0008] Specifically, the upper end face of the hollow crossbeam is provided with a first fastening hole, and the upper end face of the wedge-shaped quick-connect component is provided with a second fastening hole that mates with the first fastening hole; the fastening screws are sequentially inserted through the first fastening hole and the second fastening hole to fasten the wedge-shaped quick-connect component and the hollow crossbeam.

[0009] Secondly, this utility model provides a row of quick-assembly combination tables, comprising: At least two double workstations; A connecting component is located at the junction of two adjacent double workstations for connecting the two adjacent double workstations. The dual workstation includes two parallel table frames, a tabletop mounted on either of the table frames, a quick-release table leg structure as described above mounted on the lower end face of the two table frames, and a foot assembly mounted on the lower end face of the table legs.

[0010] Furthermore, the connecting assembly includes a wiring box fixedly mounted on two adjacent hollow crossbeams at the assembly point and a hollow upper wire post fixedly mounted on the lower end face of the wiring box; The height of the hollow upper column is less than the height of the table leg.

[0011] Furthermore, the foot assembly includes a transition reinforcement box fixedly installed on the lower end face of the table leg, a transition mounting block installed inside the transition reinforcement box, and foot screws screwed onto the transition mounting block.

[0012] Furthermore, the transition reinforcement box is made of metal, and the transition mounting block is made of plastic.

[0013] Furthermore, the dual workstation table also includes a workstation partition, which is fixedly mounted on the corresponding hollow crossbeam between the two workstations and extends out of the upper surface of the workstations.

[0014] Furthermore, the table leg includes an outer fixed cylinder and an inner lifting cylinder that is slidably connected to the outer fixed cylinder via a lifting drive assembly; The hollow crossbeam is fixedly installed on the outside of the outer fixed cylinder.

[0015] The beneficial effects of this utility model's quick-assembly table leg structure and its modular quick-assembly combination table are: This invention features a wedge-shaped quick-connect component on one side of the table legs.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] Example 1

[0033] like Figures 1-8 The present invention provides a specific embodiment of a quick-installation table leg structure 1, which includes two table legs 11 and a hollow crossbeam 12. Both ends of the hollow crossbeam 12 are connected to the two table legs 11 through quick-installation components 13. The quick-installation components 13 include a wedge-shaped quick-installation piece 131 fixedly installed on one side of the table leg 11, an n-shaped mating plate 132 fixedly installed in the cavity at the end of the hollow crossbeam 12, and a through hole 133 opened on the lower end face of the hollow crossbeam 12. The hollow crossbeam 12 and the wedge-shaped quick-installation piece 131 are fixed by fastening screws.

[0034] like Figures 4 to 8 As shown, during installation, the wedge block 1311 is inserted into the inner cavity of the hollow crossbeam 12 through the through hole 133. The mating surface of the n-shaped mating plate 132 mates with the inclined surface of the wedge quick-release piece 131. A first fastening hole 134 is provided on the upper end face of the hollow crossbeam 12, and a second fastening hole 135 is provided on the upper end face of the wedge quick-release piece 131 to mate with the first fastening hole 134. Fastening screws are sequentially inserted through the first fastening hole 134 and the second fastening hole 135 to fasten the wedge quick-release piece 131 and the hollow crossbeam 12.

[0035] In this embodiment, a wedge-shaped quick-connect component 131 is provided on one side of the table leg 11. An n-shaped mating plate 132 with the inclined surface of the wedge-shaped quick-connect component 131 is fixedly installed in the inner cavity of the hollow crossbeam 12. A through hole 133 is opened on the lower end face of the hollow crossbeam 12 for the wedge-shaped quick-connect component 131 to pass into the inner cavity of the hollow crossbeam 12. During installation, the wedge-shaped quick-connect component 131 is simply inserted from below the hollow crossbeam 12, and the hollow crossbeam 12 is fixed to the wedge-shaped quick-connect component 131 by passing the fastening screws through the first fastening hole 134 and the second fastening hole 135 in sequence. This achieves quick installation of the two table legs 11 and the hollow crossbeam 12. The assembly is relatively simple, the installation time is short, and it has a high load-bearing capacity. It does not have the loosening problem caused by the wear of the slot after repeated disassembly and reassembly of the snap-fit ​​connection method in the prior art.

[0036] In detail, the wedge-shaped quick-release component 131 in this embodiment includes a wedge-shaped block 1311 fixedly installed on one side of the table leg 11 and an inclined plate 1312 fixedly disposed on the inclined surface of the wedge-shaped block 1311. The edge of the inclined plate 1312 protrudes from the outer periphery of the wedge-shaped block 1311. The lower end of the inclined plate 1312 is inclined towards the corresponding table leg 11. The inclination direction of the mating surface of the n-shaped mating plate 132 is consistent with the inclination direction of the inclined plate 1312. In this embodiment, the lower direction of the inclined plate 1312 is inclined towards the table leg 11.

[0037] like Figure 7 and Figure 8 As shown, the through hole 133 in this embodiment includes a first through hole for the wedge block 1311 to pass through and a second through hole for the inclined plate 1312 to pass through. In this embodiment, the edge of the inclined plate 1312 protrudes beyond the outer periphery of the wedge block 1311, that is, the length and width of the inclined plate 1312 are both greater than the length and width of the wedge surface. During installation, the table leg 11 is placed on the ground, the hollow crossbeam 12 is installed from top to bottom, and the wedge block 1311 passes through the first through hole. The space penetrates into the inner cavity of the hollow crossbeam 12, and the inclined plate 1312 penetrates into the inner cavity of the hollow crossbeam 12 from the second through space. The n-shaped mating plate 132 is fixedly installed on the inner wall of the hollow crossbeam 12, and the wedge block 1311 is stuck in the middle cavity of the n-shaped mating plate 132. The mating surface of the n-shaped mating plate 132 away from the corresponding wedge block 1311 and the inclined surface of the inclined plate 1312 close to the corresponding wedge block 1311 are wedge-shaped and mated.

[0038] In this embodiment, the inclined plate 1312 on the inclined surface of the wedge block 1311 and the inclined surface of the n-shaped mating plate 132 form a wedge fit. The wedge block 1311 is designed to be wider at the top and narrower at the bottom. When the fastening screw is tightened, the hollow crossbeam 12 is guided by the mating surfaces of the inclined plate 1312 and the n-shaped mating plate 132 to gradually move closer to the table leg 11. The tighter the fastening screw is tightened, the closer the end of the hollow crossbeam 12 is to the corresponding table leg 11, thereby achieving a tight installation between the table leg 11 and the hollow crossbeam 12.

[0039] Example 2

[0040] It should be understood that the quick-assembly table leg structure 1 in this embodiment, when applied to tables with height adjustment, combination tables, or other table bodies, falls within the protection scope of this utility model. This embodiment only provides a row of quick-assembly combination tables, such as... Figures 9 to 12 As shown, the modular, quick-assembly table includes at least two double-workstation tables and a connection point between adjacent double-workstation tables for connecting them. Specifically, the double-workstation table includes two parallel table frames 3, a tabletop 4 mounted on either table frame 3, a quick-assembly table leg structure 1 as disclosed in Embodiment 1, mounted on the lower end faces of the two table frames 3, and a foot assembly 5 mounted on the lower end faces of the table legs 11.

[0041] In a preferred embodiment, the connecting component 2 includes a wiring box 21 fixedly mounted on two adjacent hollow crossbeams 12 at the assembly point, and a hollow upper wire post 22 fixedly mounted on the lower end face of the wiring box 21. The height of the hollow upper wire post 22 is less than the height of the table leg 11. The wiring box 21 in this embodiment serves two purposes: connecting the two double-workstation tables and routing cables neatly. The hollow upper wire post 22, with a height less than the table leg 11, is suspended above the lower end face of the wiring box 21, ensuring the overall neatness and aesthetics of the wiring.

[0042] As a preferred embodiment, each of the two quick-release table leg structures 1 of any double workstation is equipped with a modular cable management box for organizing and accommodating cable bundles. The modular cable management box includes an upper cable management plate, a lower cable management plate, and two cable management side plates. The upper cable management plate and the cable management side plates, as well as the lower cable management plate and the lower cable management side plates, are fixed with screws. The cable management box adopts a detachable installation form, which greatly reduces packaging space and facilitates transportation and storage.

[0043] like Figure 12As shown, the foot assembly 5 includes a transition reinforcement box 51 fixedly installed on the lower end face of the table leg 11, a transition mounting block 52 installed inside the transition reinforcement box 51, and foot screws 53 screwed onto the transition mounting block 52. In this embodiment, the transition reinforcement box 51 is made of metal, and the transition mounting block 52 is made of plastic. In this embodiment, the foot screws 53 are not directly connected to the table leg 11, but are indirectly connected through the transition reinforcement box 51 and the transition mounting block 52, so that there is a transition between the foot screws 53 and the table leg 11. The transition mounting block 52 is made of plastic to reduce costs. In this embodiment, the transition reinforcement box 51 is made of metal to match the material of the table leg 11. When the table leg 11 and the foot assembly 5 are powder coated, the color of the table leg 11 and the foot assembly 5 are kept consistent to maintain aesthetics.

[0044] In this embodiment, the table legs 11 are lifting table legs 11. The table legs 11 include an outer fixed cylinder and an inner lifting cylinder that is slidably connected to the outer fixed cylinder through a lifting drive component; the hollow crossbeam 12 is fixedly installed on the outside of the outer fixed cylinder. The two table legs 11 under one workstation can be driven synchronously by one lifting drive component, or two lifting drive components can be used to independently control the lifting of the two table legs 11. The specific adjustment is made according to the specific usage requirements or investment costs. It should be understood that, regardless of whether the form of independent lifting of a single table leg 11 or synchronous lifting of two table legs 11 is used, the drive component is a technology that is readily available to those skilled in the art, and the specific structure of the lifting drive component will not be described in detail here.

[0045] The modular table in this embodiment can ensure high structural strength and load-bearing capacity, simplify the assembly process, achieve rapid installation of the modular table, and reduce maintenance costs. It avoids the loosening problem caused by repeated disassembly, has strong adaptability, does not require high processing precision for each component, and is simple and stable to assemble.

[0046] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
