[0023] Please see Figures 1 to 5This utility model provides a technical solution: a folding combination desk, including two desktops 1, each desktop 1 having a mounting groove 2 on its opposite side, a support 3 fixed inside each mounting groove 2, and two connecting brackets 4 on the inner side of each mounting groove 2. An incomplete gear 5 is coaxially fixed to the outer side of the rotating shaft of each connecting bracket 4. Each desktop 1 has a connecting groove 6 on its opposite side, two guide rails 7 fixed inside the connecting groove 6, and an extension plate 8 slidably connected inside the connecting groove 6. Guide grooves 9 are provided on both sides of the extension plate 8, and table legs 10 are rotatably connected to both sides of the extension plate 8. A connecting rod 11 is fixed between the two table legs 10, and a first connecting rod 12 is rotatably connected to the opposite side of each table leg 10. Multiple first slots 13 are provided on the outer side of the rod 12. A sliding groove 14 is provided inside the first connecting rod 12. A second connecting rod 15 is slidably connected to the inner side of the sliding groove 14. One end of the second connecting rod 15 is rotatably connected to the outer side of the connecting frame 4. A second slot 16 is provided on the outer side of the second connecting rod 15. A pin 17 is inserted into the inner side of the second slot 16. Two incomplete gears 5 are meshed and connected. The position of the second slot 16 corresponds to the position of the first slot 13. The first connecting rod 12 is parallel to the tabletop 1. The second connecting rod 15 is parallel to the tabletop 1. The two ends of the two supports 3 are rotatably connected to the outer sides of the two connecting frames 4 respectively. The inner side of the guide groove 9 is slidably connected to the outer side of the guide rail 7. The connecting frame 4 is parallel to the table leg 10.
[0024] When unfolding the desk, the two hinged desktops 1 are gradually flattened by pulling the legs 10 to both sides. During this process, the supports 3 of the desktops 1 rotate synchronously through two meshing incomplete gears 5. At the same time, since the first connecting rod 12 is parallel to the desktop 1, the second connecting rod 15 is parallel to the desktop 1, and the connecting frame 4 is parallel to the legs 10, a parallelogram structure is formed, ensuring that the four legs 10 remain parallel. After the desktops 1 are fully unfolded, the two desktops 1 abut against each other, limiting the rotation angle of the two desktops 1 and keeping them horizontal. Meanwhile, the legs 10 are locked, and the extension length of the extension plate 8 is adjusted according to the size of the space. During this process, the second connecting rod 15 also extends from the sliding groove 14 of the first connecting rod 12. After adjustment, the pin 17 passes through the first slot 13 on the connecting rod 12 and the second slot 16 on the second connecting rod 15 to complete the fixation. Through the above process, the problem that the fixed size of the desktop after unfolding the folding table cannot meet the needs of multiple people using it at the same time is solved, which greatly limits the application range of the folding table.
[0025] The specific usage and function of this embodiment: When the desk is unfolded, the two hinged desktops 1 are gradually flattened by pulling the desk legs 10 to both sides. During this process, the support 3 of the desktop 1 rotates synchronously through two meshing incomplete gears 5. At the same time, since the first connecting rod 12 is parallel to the desktop 1, the second connecting rod 15 is parallel to the desktop 1, and the connecting frame 4 is parallel to the desk legs 10, a parallelogram structure is formed, so that the four desk legs 10 always remain parallel. After the desktop 1 is fully unfolded, the two desktops 1 abut against each other, limiting the rotation angle of the two desktops 1 and keeping the two desktops 1 horizontal. At the same time, the desk legs 10 are locked. The extension length of the extension plate 8 is adjusted according to the size of the space. During this process, the second connecting rod 15 also extends out from the sliding groove 14 of the first connecting rod 12. After the adjustment is completed, the pin 17 passes through the first slot 13 on the connecting rod 12 and the second slot 16 of the second connecting rod 15 to complete the fixation.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
