[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] According to an embodiment of the present invention, a furniture board frame connection structure is provided.

[0023] Now, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. As Figures 1-4 shown, a furniture board frame connection structure according to an embodiment of the present invention includes a table bottom frame 1 and a table top panel 2. A rectangular frame 10 is installed on the top of the table bottom frame 1, and the table top panel 2 is adhesively connected to the top surface of the rectangular frame 10. Triangular plates 5 are welded at the four corners inside the rectangular frame 10, and a plurality of positioning grooves 11 are evenly formed on the top surface of the rectangular frame 10. And a plurality of table legs 3 are fixed to the inner side surface of the rectangular frame 10 by bolts. A plurality of positioning columns 8 are integrally cast on the bottom surface of the table top panel 2, and the plurality of positioning columns 8 are respectively inserted into the plurality of positioning grooves 11 of the rectangular frame 10. Threaded columns 6 are respectively arranged at the four corners of the bottom surface of the table top panel 2, and each group of threaded columns 6 is respectively inserted through the triangular plates 5 inside the rectangular frame 10. And a nut 7 is screwed on the end of the threaded column 6 passing through the triangular plate 5. In order to increase the installation reliability of the table legs 3, two or more bolts are provided between the table legs 3 and the rectangular frame 10. The size of the table top panel 2 is larger than that of the rectangular frame 10. The rectangular frame 10 provided in this device increases the contact area with the table top panel 2. Compared with the prior art, it can avoid the poor force and easy separation of the table body to the greatest extent;

[0024] In one embodiment, a group of circular grooves are respectively formed on the bottom surface of the table top panel 2 corresponding to the threaded columns 6 in pairs. An embedded column 9 is integrally formed on the top of the threaded column 6, and the embedded column 9 is in interference connection with the circular grooves formed on the bottom surface of the table top panel 2. Through the setting of the embedded column 9, it is easy to install the threaded column 6 and the table top panel 2, so as to facilitate the connection between the table top panel 2 and the table bottom frame 1.

[0025] In one embodiment, a connecting rod 4 is welded between two adjacent table legs 3 of the table bottom frame 1, and each table leg 3 of the table bottom frame 1 has a square column structure. Through the arrangement of the connecting rod 4, the reliability of the structure between two adjacent table legs 3 is increased.

[0026] In one embodiment, two holes are provided on the surface of the triangular plate 5 corresponding to the threaded columns 6, and the thickness of the triangular plate 5 is half of the height of the rectangular frame 10. Moreover, the triangular plate 5 is attached to the bottom surface of the table top plate 2. Through the arrangement of the triangular plate 5, the connection between the triangular plate 5 and the table top plate 2 is facilitated.

[0027] In one embodiment, the table top plate 2 is composed of a wrapping shell made of aluminum alloy and a marble panel embedded and installed inside it. The wrapping shell of the table top plate 2 provides a protective structure for the marble panel (the connection structure diagram of the wrapping shell and the marble panel is not shown), and it is also easy to install the threaded columns 6 and the positioning columns 8.

[0028] In one embodiment, bolts are inserted and installed in the upper part of the table legs 3, and one end of the bolts is fixedly connected to the inner side surface of the rectangular frame 10. Through the arrangement of the bolts, the connection between the table legs 3 and the rectangular frame 10 is facilitated.

[0029] Working principle:

[0030] When in use, by bringing the table top plate 2 into contact with the rectangular frame 10 at the top of the table bottom frame 1, a plurality of positioning columns 8 of the table top plate 2 are inserted into a plurality of positioning grooves 11 of the table bottom frame 1, so as to perform the initial positioning of the installation of the table top plate 2 and the table bottom frame 1. Since threaded columns 6 are press-fitted with embedded columns 9 at the four corners of the bottom surface of the table top plate 2 respectively, and triangular plates 5 are welded at the inner corners of the rectangular frame 10 of the table bottom frame 1, with the preliminary positioning of the table top plate 2 and the table bottom frame 1, the pairwise arranged threaded columns 6 are inserted into the holes provided on the surface of the triangular plates 5. Combining with the nuts 7 screwed on the ends of the threaded columns 6 passing through the triangular plates 5, the fixation of the table top plate 2 and the table bottom frame 1 is realized. When disassembly is required, directly disassemble the nuts 7 on the surface of the threaded columns 6, and the table top plate 2 can be separated from the table bottom frame 1.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
