Description

Technical Field

[0001] This utility model relates to the technical field of tables, specifically to a connecting structure for installing table legs and a table. Background Technology

[0002] Reading rooms, libraries, conference rooms, and other spaces for studying, reading, or working often have numerous reading tables or conference tables. These typically consist of a basic tabletop and four legs, with a simple overall structure. When the existing reading tables are relatively short, the simple combination of four legs and the tabletop provides stable support and prevents deformation or bending. However, when the span of the tabletop exceeds two meters, deformation begins to occur, with the deformation becoming more severe as the span increases. Especially when the tabletop exceeds 3 meters, without additional auxiliary structures for rigid positioning, the tabletop is prone to deformation and bending over time, and the two side panels may also be compressed and twisted. To address the support problem of large-span tabletops, current technologies often use large steel plates welded together. This increases the table's weight, making it difficult to move, package, and transport, and is also aesthetically unappealing. Multi-legged supports, on the other hand, are less aesthetically pleasing. At the same time, when the existing tabletop and table legs are connected by conventional mortise and tenon joints or screws, the problem of gravity points can easily cause wobbling during use. It is also relatively troublesome to disassemble and transport, and it is easy to cause local breakage at the connection between the table legs or tabletop due to insufficient rigidity. Utility Model Content

[0003] In order to solve one or more technical problems existing in the prior art, one of the objectives of this application is to provide a connection structure for installing table legs, which enables the installation of tabletop and table legs to be more flexible, has better stability after installation, and can improve the torsional resistance of the tabletop.

[0004] The second objective of this application is to provide a table assembled using a connecting structure for mounting table legs. The overall structure has high stability and can be used for a long time without deformation and stable placement without any auxiliary support. This effectively improves the overall aesthetics and ease of installation of the reading table, and is also convenient for disassembly and transportation.

[0005] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0006] A connecting structure for mounting table legs includes an aircraft nose frame and a counterweight. The counterweight includes a cylindrical counterweight body and a connecting screw on the top of the counterweight body. The counterweight body has a connecting screw hole for mounting the connecting screw. The aircraft nose frame includes an L-shaped insert block and a protrusion on the inner side of the corner of the L-shaped insert block. The connecting screw hole is located on the protrusion.

[0007] Preferably, the counterweight has a disassembly hole on one side.

[0008] Preferably, the disassembly hole penetrates the counterweight or one end is connected to the connecting screw hole.

[0009] The second objective of this application is achieved through the following technical solution:

[0010] A table includes a tabletop and table legs, which are connected by a connecting structure. An aircraft nose frame is mounted at the corner of the tabletop, and the table legs are detachably mounted on the aircraft nose frame via a counterweight.

[0011] Preferably, the desktop includes a honeycomb core panel and a panel disposed on the outer side of the honeycomb core panel, and the aircraft nose frame is embedded in the corner of the honeycomb core panel.

[0012] Preferably, it also includes a locking screw, the bottom of the counterweight is provided with a locking screw hole, the bottom of the storage groove is provided with a mounting hole that passes through the table leg, and one end of the locking screw passes through the mounting hole through the bottom of the table leg and is threaded into the connecting screw hole.

[0013] Preferably, the bottom of the table leg is provided with a steel foot, and one end of the locking screw is limited by the steel foot.

[0014] Preferably, the top of the table leg is provided with an upwardly protruding limiting block, and the bottom of the tabletop is provided with a limiting slot that cooperates with the limiting block to lock and limit the position.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The aircraft-nose frame helps to shape the corners and sides of the desktop, improving its torsional resistance and ensuring it remains flat even with increased span. Furthermore, the embedded frame maintains the flatness of the desktop, preventing any visible bulges and enhancing its aesthetics. It also avoids increased transport difficulty due to weight, and even protects the desktop corners from impacts.

[0017] 2. The counterweights ensure that the table's weight is always on the legs during placement, creating a downward force that increases the overall stability of the table and prevents wobbling. This also improves the table's aesthetics and ease of installation.

[0018] 3. By combining the aircraft nose frame and counterweights, the tabletop will not twist or deform or become unstable during placement even when the span of the study table exceeds 3m, effectively increasing the tabletop length of the large-span reading table. Attached Figure Description

[0028] like Figure 1 As shown and Figure 2 As shown, taking a large-span reading table as an example, it includes a tabletop 7 and table legs 1. The corner of the tabletop 7 is provided with an aircraft-nose frame 6, and the table legs 1 are provided with counterweights 4. The upper end of the table legs 1 is detachably installed on the aircraft-nose frame 6. The counterweight 4 includes a cylindrical counterweight body 41 and a connecting screw 43 on the top of the counterweight body 41. The top of the table legs 1 is provided with a storage groove 2, and the bottom of the tabletop 7 is provided with a connecting screw hole 8 for installing the connecting screw 43. The counterweight body 41 is embedded in the storage groove 2. The aircraft-nose frame 6 includes L-shaped inserts 62 extending along both sides of the tabletop 7 and a protrusion 61 on the inner side of the corner of the L-shaped insert 62. The connecting screw hole 8 is provided on the protrusion 61. The aircraft-nose frame 6 improves the deformation resistance at the corners and sides of the tabletop 7, and the counterweight 4 improves the stability of the table legs 1 during the support process.

[0029] The counterweight 4 consists of a cylindrical counterweight body 41 and a connecting screw 43. The counterweight 4 is generally made of metal, which allows it to exert greater downward pressure on the table leg 1 after assembly, resulting in better stability. Furthermore, the cylindrical structure of the counterweight body 41 effectively solves the problem of inaccurate alignment with the storage slot 2 after installation via the connecting screw 43, or the angle deviation of the table leg 1 after insertion into the storage slot 2. This significantly increases the installation difficulty when the table leg 1 cannot be installed at any angle. The counterweight 4 is a separate component; the table leg 1 is connected to the tabletop 7 via the counterweight 4, making transportation more convenient and reducing packaging and transportation costs. After the counterweight body 41 is installed into the connecting screw hole 8 via the connecting screw 43, installing the table leg 1 simply requires aligning the storage slot 2 with the counterweight body 41 and inserting it. This installation method is simpler and more convenient. When no other fixing structure is used, the counterweight body 41 and the storage slot 2 can be connected using an interference fit or a transition fit. After the L-shaped insert 62 is embedded into the corner of the tabletop 7, the connecting edge of the L-shaped insert 62 extends along the side of the tabletop 7, which can effectively provide rigid support and limit the corner of the tabletop 7, avoiding relative twisting at the two sides of the corner, thereby improving the deformation resistance of the entire tabletop 7. At the same time, the simple L-shaped insert 62, after installation, is prone to deformation due to the torsion of the tabletop 7, even if it is made of metal, because the weight of the entire tabletop 7 needs to be reduced. Secondly, the connecting screw hole 8 is located on the tabletop 7, and the connecting screw 43 is prone to breakage due to external force after being inserted, which may cause the connection between the tabletop 7 and the table leg 1 to loosen. Therefore, a protrusion 61 is formed on the inner side of the corner of the L-shaped insert 62. The protrusion 61 makes the L-shaped insert 62 form an airplane nose structure. The connecting screw hole 8 is located on the protrusion 61. The airplane nose frame 6 is made of metal. The protrusion 61 can not only support the corner of the plate-shaped L-shaped insert 62, making the rigidity between the two sides of the L-shaped insert 62 better and the deformation resistance stronger, but also ensure that the connecting screw 43 will not loosen even when subjected to external force after being installed, making the connection between the two more secure. At the same time, the metal airplane nose frame 6 can further increase the weight of the table leg 1, so that the entire reading table will not wobble when placed anywhere.

[0030] Because the tabletop 7 is prone to deformation and twisting due to the torsional force on the edges of the board after its span increases, adding auxiliary supports to the bottom or sides of the tabletop 7 can help prevent torsional deformation, but it also significantly increases the overall weight of the tabletop 7, making transportation more difficult, reducing aesthetics, and increasing costs. Therefore, to solve the problem of the tabletop 7 easily deforming when its span is increased without auxiliary supports, an aircraft-nose frame 6 is embedded at the corner of the existing tabletop 7. The aircraft-nose frame 6 can stabilize the corners and a certain length of the side of the tabletop 7, thereby improving the tabletop 7's resistance to torsion and allowing it to remain flat for a long time even after the span is increased. Meanwhile, the aircraft-shaped frame 6 is embedded in the desktop 7, so that the overall appearance of the desktop 7 is still a sheet-like material. From the appearance, there will be no local protrusions, which is aesthetically pleasing. Moreover, after installation, there will be no problem of increased transportation difficulty due to excessive weight. The aircraft-shaped frame 6 can even protect the corners of the desktop 7, preventing extensive damage to the corners due to collisions.

[0031] Because the existing reading table's desktop 7 has a flat structure with uniform overall weight, it is prone to instability during use, especially when the desktop 7 is relatively thin. Due to the increased span of the desktop 7, the installation stability is worse than that of a conventional reading table. Therefore, a counterweight 4 was added to the table leg 1, ensuring that the weight of the reading table is always on the table leg 1 during placement. This allows the table leg 1 to naturally generate a downward force, thus increasing the overall structural stability of the table leg 1 during use and reducing the likelihood of wobbling. This effectively improves the overall aesthetics and ease of installation of the reading table. The combination of the aircraft-shaped frame 6 and the counterweight 4 ensures that even when the span of the study table exceeds 3 meters, there will be no twisting or deformation of the desktop 7 or instability during placement, effectively increasing the length of the desktop 7 for large-span reading tables.

[0032] Further improvements include, for example Figure 4 As shown, it also includes a locking screw 10. The bottom of the counterweight 41 is provided with a locking screw hole 44. The bottom of the storage groove 2 is provided with a mounting hole 9 that passes through the table leg 1. One end of the locking screw 10 passes through the mounting hole 9 through the bottom of the table leg 1 and is threaded into the connecting screw hole 8.

[0033] When using counterweight 4 to connect table legs 1 and tabletop 7, the dimensions and fitting precision of the storage slot 2 are critical, and disassembly after installation is also difficult. Furthermore, connecting via the storage slot 2 can easily lead to localized stress on table legs 1, causing damage to the sides of the table legs 1 near the storage slot 2. Therefore, a locking screw 10 is added to each table leg 1. The locking screw 10 passes through the mounting hole 9 from the bottom of the table leg 1 and connects to the locking screw hole 44. The combination of the locking screw 10 and the counterweight 4 provides rigid reinforcement to the table legs 1. The cooperation between the locking screw 10 and the locking screw hole 44 ensures that the table legs 1 are securely installed on the counterweight 41. This also reduces the requirements for the fit between the storage slot 2 and the counterweight 41, allowing for better relative rotation and assembly / disassembly, and preventing difficulties in disassembling the table legs 1 after installation. Meanwhile, by combining the locking screw 10, the counterweight 4, and the aircraft nose frame 6, the fastening structure of the table leg 1 can form a whole that runs through the entire table leg 1, making the table leg 1 more secure and stable after installation. Even if subjected to shearing force, it can prevent the table leg 1 from loosening or even breaking. Compared with the existing connection structure, it provides better protection for the table leg 1.

[0034] A further improvement is made by providing a disassembly hole 42 on one side of the counterweight 41.

[0035] After installation, the counterweight 4 is cylindrical in shape, making it difficult to disassemble using ordinary tools. When disassembling by hand with a rotating handle, it is easy to become stuck due to rust caused by long-term installation. Therefore, in order to solve the problem of the counterweight 4 being unable to be disassembled due to the lack of a force-bearing point, a disassembly hole 42 is formed on one side of the counterweight 41. The disassembly hole 42 can form a radial force-bearing point during both disassembly and installation, making disassembly and installation more convenient.

[0036] Further improvements include, for example Figure 2 and Figure 3 As shown, the disassembly hole 42 penetrates the counterweight 41 or one end is connected to the connecting screw hole 8.

[0037] The disassembly hole 42 penetrates through the counterweight 41, simplifying the structure. Meanwhile, due to the limited overall diameter of the counterweight 41, to ensure its overall counterweight effect while increasing the load-bearing length of the disassembly hole 42, one end of the disassembly hole 42 is connected to the connecting screw hole 8, forming a T-shaped structure. This not only maintains the function of the two holes but also maximizes the weight of the counterweight 4, while indirectly increasing the length of the disassembly hole 42 through the connecting screw hole 8.

[0038] A further improvement is that the bottom of the table leg 1 is provided with a steel foot 11, and one end of the locking screw 10 is limited by the steel foot 11.

[0039] Since table legs 1 are generally made of wood, the tightening screw 10 can easily cause clamping force during tightening, damaging the bottom of table legs 1. Furthermore, it does not limit the left and right positions of the tightening screw 10. To ensure the installation stability of the tightening screw 10, a steel foot 11 is installed at the bottom of table legs 1. The tightening screw 10 passes through the steel foot 11 before being tightened. This allows the bottom of the tightening screw 10 to be axially and radially limited by the steel foot 11, preventing excessive axial rotation and radial displacement of the tightening screw 10 during installation.

[0040] A further improvement is that the top of the table leg 1 is provided with an upwardly protruding limiting block 3, and the bottom of the tabletop 7 is provided with a limiting slot 5 that cooperates with the limiting block 3 to lock and limit the position.

[0041] When assembling table leg 1, in order to avoid positional deviation of table leg 1 after assembly and lack of positioning effect after installation, and also to facilitate the exposure of the threaded hole part on the aircraft nose frame 6, an inwardly recessed limiting groove 5 is formed at the bottom of the tabletop 7. This allows part of the perforated part of the aircraft nose frame 6 to be placed in the limiting groove 5, and at the same time, through the limiting block 3 on the top of table leg 1, the assembled tabletop 7 and table leg 1 can also have a limiting function, preventing table leg 1 from rotating or shaking after installation.

[0042] Further improvements include, for example Figure 5 As shown, the desktop 7 includes a honeycomb core panel 72 and a panel 71 disposed on the outside of the honeycomb core panel 72, and the aircraft nose frame 6 is embedded in the corner of the honeycomb core panel 72.

[0043] In actual production, the desktop 7 is composed of a honeycomb core panel 72 and a panel 71. The aircraft nose frame 6 is embedded in the corner of the honeycomb core panel 72, which makes the overall weight of the desktop 7 lighter and its deformation resistance better. The panel 71 can effectively shield the honeycomb core panel 72 and the aircraft nose frame 6, making the desktop 7 more beautiful and its deformation resistance better. It can achieve stable use over a larger span without other auxiliary structures.

[0044] A further improvement is made in that the honeycomb core panel 72 is a fully diamond honeycomb structure; the panel 71 is made of solid wood; the upper surface of the desktop 7 is also provided with a medium fiber tabletop 73; and the honeycomb core panel 72 is made of aluminum.

[0045] The honeycomb core panel 72 is made of aluminum, which makes it more rigid and stronger in terms of resistance to deformation. The span of the desktop 7 can be larger. Especially when the honeycomb core panel 72 is a full-diameter aluminum honeycomb structure, when combined with the medium fiber tabletop 73, it can support the ultra-large span preview table without any auxiliary support. After testing, it was found that even with a span of 3.5m, there will be no swaying, bending or deformation. The large-span reading table can remain stable even when placed anywhere.
