[0003] In order to improve the user experience and increase the comfort of the user's skin when the table is in contact with the table, the table top is usually made of wood materials (such as artificial boards, logs, etc.).

[0004] However, tables with wooden tabletops are often heavy, and the legs of the tables are often fixedly connected to the tabletops, which makes the table more time-consuming and labor-intensive to move, and the table also occupies a larger space when stored.

[0005] For existing tables with detachable legs and table tops, the connection between the legs and the table top is prone to loosening and damage due to repeated disassembly, thereby affecting the service life of the table. Utility Model Content

[0006] The present application provides a table that can facilitate the disassembly and assembly of the table legs and the table top so that the table can be used, carried and stored, and can effectively reduce the impact of the disassembly and assembly of the table legs and the table top on the stability of the table structure.

[0044] The following is combined with Figure 1-6 This application is described in further detail.

[0045] Example 1:

[0046] Reference Figure 1 and Figure 2 The present application discloses a table comprising a table top 1, at least four table legs 2, and at least four connecting tubes 3, wherein the number of connecting tubes 3 is equal to the number of table legs 2. In this embodiment, the table top 1 is preferably made of a wood material (such as artificial board, logs, etc.); and the table preferably includes a total of four table legs 2.

[0047] The table top 1 is a rectangular plate-like structure as a whole, and the bottom of the table top 1 is provided with mounting grooves 11 adapted to the connecting tube 3 near the four corners; the connecting tube 3 is a cylindrical structure as a whole, and the axis of the mounting groove 11 is perpendicular to the bottom surface of the table top 1.

[0048] Reference Figure 2 and Figure 3 The connecting tube 3 has a connecting groove 31 for connecting the table legs 2 thereto, and the connecting groove 31 has an opening formed at one end of the connecting tube 3 in the axial direction. The connecting tube 3 also has a plurality of first ventilation holes 32. The first ventilation holes 32 are located at the end of the connecting tube 3 away from the opening of the connecting groove 31. The first ventilation holes 32 pass through the connecting tube 3 and communicate with the connecting groove 31. In this embodiment, preferably, the connecting tube 3 has a total of one first ventilation hole 32, and the axis of the first ventilation hole 32 coincides with the axis of the connecting tube 3.

[0049] After the connecting tube 3 is installed in the installation groove 11 , the opening of the connecting groove 31 is located at the bottom of the table top 1 , and the end surface of the connecting tube 3 near the opening is flush with the bottom surface of the table top 1 .

[0050] The connection tube 3 and the tabletop 1 are connected by an interference fit, meaning the radial dimension of the connection tube 3 is slightly larger than the radial dimension of the connection groove 31. Furthermore, the surface of the connection tube 3 and the wall of the connection groove 31 are securely connected by glue, which fills the gap between the connection tube 3 and the wall of the connection groove 31 after the connection tube 3 is installed. In this embodiment, glue is preferably applied to the wall of the connection groove 31 before the connection tube 3 is installed, and then a force is applied to the connection tube 3 to ensure that the connection tube 3 and the connection groove 31 are plugged into each other.

[0051] The connecting groove 31 is in the shape of a cylindrical structure. The axis of the connecting groove 31 coincides with the axis of the connecting cylinder 3 , and the groove wall in the radial direction of the connecting groove 31 has an internal thread.

[0052] The table leg 2 is a rectangular parallelepiped structure with a square cross-section. One end of the table leg 2 in the length direction has a connecting portion 21 for detachable connection with the connecting tube 3. The connecting portion 21 is adapted to the connecting groove 31, that is, the shape of the connecting portion 21 is also a cylindrical structure, and the axis of the connecting portion 21 coincides with the center line of the table leg 2; the radial surface of the connecting portion 21 has an external thread, and the connecting portion 21 is threadedly matched with the connecting tube 3, that is, a detachable connection is achieved by threaded matching.

[0053] After the table leg 2 is fully threadedly engaged with the connecting tube 3 through the connecting portion 21, the end surface of the table leg 2 near the connecting portion 21 is in contact with the bottom surface of the table top 1. In this embodiment, it is preferred that after the table leg 2 is fully threadedly engaged with the connecting tube 3 through the connecting portion 21, the four end surfaces of the table leg 2 are parallel to the four peripheral surfaces of the table top 1.

[0054] Furthermore, in order to reduce the overall mass of the table, it is preferred that the interior of the table leg 2 has a cavity 22, and the shape of the cavity 22 is preferably a rectangular structure with a square cross-section; the center line of the cavity 22 coincides with the center line of the table leg 2, and the cavity 22 forms an opening at the end of the table leg 2 away from the connecting portion 21.

[0055] Furthermore, to ensure the structural strength of the table leg 2, a reinforcement structure 23 is preferably fixedly mounted within the cavity 22 of the table leg 2, with the reinforcement structure 23 forming a connection between the inner walls of the cavity 22, thereby reducing the probability of deformation of the table leg 2 under stress. In this embodiment, the reinforcement structure 23 is preferably a rectangular sheet-like structure, with two sides of the reinforcement structure 23 fixedly connected to opposite inner walls of the cavity 22, thereby dividing the cavity 22 into two equal-sized spaces. In other embodiments, the reinforcement structure 23 may also be a cross-shaped structure with four sides fixedly connected to the four inner walls of the cavity 22.

[0056] Furthermore, in order to facilitate the detachable connection between the table leg 2 and the connecting tube 3 through the connecting part 21 in a threaded manner, and to reduce the probability that a closed space is formed after the connecting part 21 and the connecting tube 3 are fully threaded together, which makes it difficult to separate the table leg 2 from the connecting tube 3 due to the subsequent air pressure difference, it is preferred that the table leg 2 is also provided with a plurality of second air holes 24 on the connecting part 21.

[0057] One end of the second ventilation hole 24 extends through the end of the connecting portion 21 to form an opening, and the other end of the second ventilation hole 24 communicates with the end of the cavity 22, away from the opening. In this embodiment, the table leg 2 preferably has one second ventilation hole 24 defined in the connecting portion 21, and the axis of the second ventilation hole 24 preferably coincides with the centerline of the table leg 2.

[0058] The implementation principle of a table in the embodiment of the present application is as follows:

[0059] During the first assembly, glue is first applied to the wall of the mounting groove 11 of the table top 1, and then the connecting tube 3 is installed in the mounting groove 11 in an interference fit manner, so that the glue fills the gap between the connecting tube 3 and the wall of the mounting groove 11, and then wait for the glue to solidify; then the table leg 2 is fully threaded into the connecting tube 3 through the connecting portion 21, and the installation of the table leg 2 is completed and the table can be used;

[0060] When the table needs to be transported or stored, the table leg 2 is controlled to rotate relative to the connecting tube 3 so that the threaded engagement between the connecting portion 21 and the connecting tube 3 is released, and the table leg 2 can be removed, and the table top 1 and the table leg 2 can be separated for transport or storage.

[0061] Example 2:

[0062] Reference Figure 2 and Figure 4The difference between this embodiment and embodiment 1 lies in the connecting tube 3 and the table leg 2.

[0063] Reference Figure 4 and Figure 5 The radial outer surface of the connecting tube 3 has a plurality of raised strips 33 extending parallel to the axis of the connecting tube 3. The raised strips 33 are arranged in a circular array around the axis of the connecting tube 3. Once the connecting tube 3 is installed in the mounting slot 11, the raised strips 33 increase the resistance to rotation of the connecting tube 3 relative to the table top 1, thereby further improving the positional stability of the connecting tube 3 relative to the table top 1 after installation.

[0064] Furthermore, it is preferred that the protrusion of the ridges 33 gradually decreases as it approaches the first vent hole 32, that is, the ridges 33 tend to shrink as they approach the first vent hole 32. In this case, the multiple ridges 33 can not only improve the positional stability of the connecting tube 3 after installation, but also facilitate the interference fit of the connecting tube 3 with the installation groove 11 after a force is applied.

[0065] An extension portion 34 extends radially outward from the edge of the connecting tube 3 near the opening of the connecting groove 31. The extension portion 34 is an annular sheet structure, and the axis of the extension portion 34 coincides with the axis of the connecting tube 3. After the connecting tube 3 is installed in the mounting groove 11, the extension portion 34 will be located below the table top 1 and will fit against the bottom surface of the table top 1. At this time, the extension portion 34 can provide the user with a larger force point during the installation of the connecting tube 3, so that the connecting tube 3 and the mounting groove 11 can achieve an interference fit; during the subsequent installation of the table leg 2, the end of the table leg 2 near the connecting portion 21 will contact and abut against the extension portion 34, so as to reduce the wear caused by the direct contact between the table leg 2 and the table top 1.

[0066] Furthermore, preferably, the end of the ridge 33 away from the first vent hole 32 is fixedly connected to the extension portion 34. In this case, the ridge 33 acts as a reinforcement for the extension portion 34, which can effectively improve the overall structural strength of the connecting tube 3 and extend the service life of the connecting tube 3.

[0067] Furthermore, the connecting tube 3 preferably has a sealing ring 4 detachably connected to the extension 34. A first positioning groove 341 is defined on the end surface of the extension 34, adjacent to the first vent 32, to accommodate the sealing ring 4. Both the first sealing ring 4 and the first positioning groove 341 are annular in shape, with the axis of the first positioning groove 341 coinciding with the axis of the connecting tube 3. When the sealing ring 4 is installed within the first positioning groove 341, a portion of the sealing ring 4 is positioned outside the first positioning groove 341. In this embodiment, since the sealing ring 4 is a common prior art component, its detailed description is omitted and is only briefly illustrated in the accompanying drawings.

[0068] At this time, after the connecting tube 3 is installed in the installation groove 11, the extension part 34 will fit against the bottom surface of the table board 1, and the sealing ring 4 installed in the first positioning groove 341 will be squeezed and deformed between the bottom surface of the table board 1 and the extension part 34. At this time, the squeezed and deformed sealing ring 4 can seal the gap between the connecting tube 3 and the wall of the installation groove 11, preventing external impurities from entering, thereby reducing the probability of corrosion and aging here, and can effectively extend the service life of the connecting tube 3 after installation.

[0069] When the table leg 2 is fully threadedly engaged with the connecting tube 3 through the connecting portion 21, the end surface of the table leg 2 near the connecting portion 21 will abut against the end surface of the extension portion 34. To reduce wear on the connecting portion 21 and the connecting tube 3 during the threaded engagement, an elastic pad 5 is preferably detachably connected to the table leg 2 near the connecting portion 21.

[0070] The elastic pad 5 is annular in structure. A second positioning groove 25 is defined at one end of the table leg 2, adjacent to the connecting portion 21, to mate with the elastic pad 5. The second positioning groove 25 surrounds the connecting portion 21, and the axis of the second positioning groove 25 coincides with the axis of the connecting portion 21. When the elastic pad 5 is installed in the second positioning groove 25, a portion of the elastic pad 5 is positioned outside the second positioning groove 25. In this embodiment, the elastic pad 5 is preferably made of rubber.

[0071] At this time, when the table leg 2 is fully threadedly engaged with the connecting tube 3 through the connecting portion 21, the end face of the table leg 2 close to the connecting portion 21 will fit against the end face of the extension portion 34, and the elastic pad 5 installed in the second positioning groove 25 will be squeezed and deformed between the extension portion 34 and the end of the table leg 2 close to the connecting portion 21. At this time, the squeezed elastic pad 5 can play a buffering effect between the connecting tube 3 and the table leg 2, reducing the wear between the two.

[0072] The implementation principle of a table in the embodiment of the present application is as follows:

[0073] During assembly, first apply glue on the groove wall of the installation groove 11 of the table top 1, then install the sealing ring 4 in the first positioning groove 341, and then install the connecting tube 3 in the installation groove 11 in an interference fit manner, so that the glue fills the gap between the connecting tube 3 and the groove wall of the installation groove 11, and makes the extension part 34 fit against the bottom surface of the table top 1, and then wait for the glue to solidify; then install the elastic pad 5 in the second positioning groove 25, and then completely thread the table leg 2 with the connecting tube 3 through the connecting part 21, so that the end face of the table leg 2 fits against the end face of the extension part 34, and then the installation of the table leg 2 is completed and the table can be used.

[0074] Example 3:

[0075] Reference Figure 4 and Figure 6 The difference between this embodiment and embodiment 2 lies in the convex strip 33.

[0076] Reference Figure 6 To improve the positional stability of the connecting tube 3 after installation on the table top 1 and reduce the probability of the connecting tube 3 being disengaged from the mounting groove 11, the outer side of the protrusion 33 preferably has a plurality of barbs 331. The barbs 331 are evenly spaced and connected end to end along the inclined direction of the outer side of the protrusion 33. In this embodiment, the barbs 331 preferably have a triangular prism structure.

[0077] The implementation principle of a table in the embodiment of the present application is as follows:

[0078] During the installation of the connecting tube 3 on the table top 1 , the barbs 331 have little effect on the plug-in fit between the connecting tube 3 and the installation slot 11 ;

[0079] When the connecting tube 3 is installed on the table top 1 , the barbs 331 can effectively increase the resistance that the connecting tube 3 needs to overcome when leaving the installation groove 11 .

[0080] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
