[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown in the figure, the tabletop adjustment component for a dining table provided in this embodiment of the utility model includes a dining table body 1 and an extension plate 2. The extension plate 2 is rotatably connected to the front and rear sides of the dining table body 1 via a pivot. Both sides of the bottom front and rear sides of the dining table body 1 are fixedly connected to protrusions 3. Both sides of the bottom of the extension plate 2 are fixedly connected to fixing plates 4. The inner cavity of the protrusion 3 is provided with a movable groove 5. The inner cavity of the movable groove 5 is provided with a support mechanism 6. The right side of the inner cavity of the right movable groove 5 is provided with a control mechanism 7 that works in conjunction with the support mechanism 6.

[0027] refer to Figure 3 and Figure 4The support mechanism 6 includes a limiting block 601. A support rod 602 is fixedly connected to the front side of the front limiting block 601. The side of the support rod 602 away from the limiting block 601 passes through the protrusion 3 and extends to the outside of the protrusion 3. A support column 603 that cooperates with the support hole 8 is fixedly connected to the side of the front support rod 602 near the support hole 8. A limiting groove 604 that cooperates with the control mechanism 7 is opened on the right side of the right limiting block 601.

[0028] The above solution is adopted: by setting up the support mechanism 6, the extension plate 2 can be supported, making it convenient for users to use the extension plate 2.

[0029] refer to Figure 3 and Figure 4 The control mechanism 7 includes a torsion bar 701. A control plate 702 is fixedly connected to the front side of the torsion bar 701. A slide bar 703 is fixedly connected to the left side of the control plate 702. A fixing block 704 is provided on the side of the slide bar 703 near the limiting groove 604 to cooperate with the limiting groove 604. A spring 705 is fixedly connected to the top of the fixing block 704. A sliding groove 706 is opened on the side of the fixing block 704 near the slide bar 703 to cooperate with the slide bar 703. The side of the torsion bar 701 away from the limiting block 601 passes through the protrusion 3 and extends to the outside of the protrusion 3. The bottom of the fixing block 704 passes through the protrusion 3 and extends to the outside of the protrusion 3.

[0030] The above solution allows for the control of the support mechanism 6 by setting up a control mechanism 7, making it convenient for users to operate the control mechanism 7.

[0031] refer to Figure 2 The right side of the fixing plate 4 has a support hole 8 for use with the support column 603.

[0032] The above solution allows the support rod 602 to push the support column 603, thus unfolding the extension plate 2 and facilitating its use.

[0033] refer to Figure 3 The front of the front protrusion 3 has a first through hole 9 that works with the support rod 602. The front and rear sides of the bottom of the protrusion 3 have second through holes 10 that work with the fixing block 704. The right side of the right protrusion 3 has a third through hole 11 that works with the torsion rod 701.

[0034] The above solution is adopted: by setting the first through hole 9 and the second through hole 10, the support rod 602 and the fixing block 704 can be limited respectively, and by setting the third through hole 11, the travel direction of the torsion bar 701 can be restricted.

[0035] refer to Figure 3The side of the limiting block 601 near the inner wall of the movable groove 5 contacts the inner wall of the movable groove 5, the side of the support rod 602 near the inner wall of the first through hole 9 contacts the inner wall of the first through hole 9, and the side of the support column 603 near the inner wall of the support hole 8 contacts the inner wall of the support column 603.

[0036] Using the above solution: by setting the limiting block 601, the support rod 602 can be limited; by setting the support rod 602 to drive the support column 603, the fixed plate 4 can be pushed, so that the extension plate 2 can be unfolded.

[0037] refer to Figure 3 and Figure 4 The torsion bar 701 is rotatably connected to the limit block 601 via a rotating shaft on the side near the limit block 601. The side of the torsion bar 701 near the inner wall of the third through hole 11 is in contact with the inner wall of the third through hole 11. The side of the slide bar 703 near the inner wall of the slide groove 706 is in contact with the inner wall of the slide groove 706. The side of the fixing block 704 near the inner wall of the limit groove 604 is in contact with the inner wall of the limit groove 604. The bottom of the spring 705 is fixedly connected to the inner wall of the limit groove 604.

[0038] The above scheme is adopted as follows: by setting the torsion bar 701, the control plate 702 can be rotated; by setting the slide bar 703, the fixed block 704 can be moved; by setting the spring 705, the fixed block 704 can be reset; and by setting the fixed block 704, the limit block 601 can be fixed.

[0039] The working principle of this utility model:

[0040] In use, the user rotates the torsion bar 701, which drives the control plate 702 to rotate. The control plate 702, through the slide bar 703, drives the fixing block 704 to compress the spring 705 and enter the inner cavity of the movable groove 5. The user pulls the extension plate 2, pushing the torsion bar 701. The torsion bar 701 drives the limiting block 601 to move in the inner cavity of the movable groove 5, so that the limiting block 601 drives the support column 603 to move through the support rod 602. When the extension plate 2 is unfolded, the user releases the torsion bar 701. The force released after the spring 705 is compressed pushes the fixing block 704 to move in the opposite direction and insert into the inner cavity of the second through hole 10. At the same time, the fixing block 704 drives the control plate 702 to rotate in the opposite direction and reset through the slide bar 703, thus completing the use.

[0041] In summary, this tabletop adjustment component for a dining table, through the coordinated use of the movable groove 5, support mechanism 6, and control mechanism 7, allows the torsion bar 701 to rotate, which in turn drives the control plate 702 to rotate. The control plate 702, via the slide bar 703, drives the fixing block 704 to compress the spring 705, which then enters the inner cavity of the movable groove 5. This solves the problem that some existing dining tables are inconvenient to operate when the tabletop is unfolded, thus affecting the use of the dining table.
