That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a stabilizing device for a lightweight dining table board with a backrest, comprising a dining table board 1, wherein a plurality of grooves 9 are provided on a side surface of the dining table board 1 facing the backrest, and a limiting column 4 is provided in the groove 9 for making the dining table board 1 contact with the backrest and limiting the dining table board 1, a plurality of positioning grooves 5 are provided on one side of the groove 9, and a connecting groove is provided on the limiting column 4, in which a positioning plate 7 is movably installed through a pin shaft, and the other end of the positioning plate 7 is inserted into the corresponding positioning groove 5, a hidden groove 2 is provided at one end of the dining table board 1, and a limiting ring 3 for placing cups is provided in the hidden groove 2, and a plurality of supporting components are installed on the inner ring surface of the limiting ring 3, and a plurality of telescopic rods 13 are installed between the limiting ring 3 and the hidden groove 2.

[0021] In this embodiment, the support components include a support plate 11 and a bottom plate 12, and the support plate 11 and the bottom plate 12 are stacked one above the other. One end of the support plate 11 is fixedly connected to the limit ring 3 through a hinge, and one end of the bottom plate 12 is fixedly connected to the support plate 11 through a hinge. The sum of the width of the support plate 11 and the bottom plate 12 is less than the width of the hidden groove 2.

[0022] In this embodiment, a card slot 6 is provided on the bottom surface of the positioning groove 5, and a card block is protruded on the bottom surface of the positioning plate 7. The card block is inserted into the corresponding card slot 6 and is fixed with the card slot 6. The inserted positioning plate can be positioned by the card connection, thereby preventing the positioning plate from lifting up by itself. An operating port 8 is provided on the positioning plate, and a finger can be inserted into the operating port to lift the positioning plate upward.

[0023] In this embodiment, the cross-section of the limiting column 4 is arranged in a rectangular structure, and both side surfaces of the limiting column 4 are arranged in contact with the inner side surface of the groove 9 .

[0024] In this embodiment, a positioning channel is provided at one end of the limit column 4, and a positioning column 10 is provided in the positioning channel. One end of the positioning column 10 is installed on the inner wall surface of the groove 9. The cross-sections of the positioning channel and the positioning column 10 are both arranged in a rectangular structure, so that the limit column can only move along the positioning column, thereby avoiding the rotation of the limit column.

[0025] In this embodiment, a portion of the limiting ring 3 protrudes out of the hidden groove 2, so that a finger can be inserted into the limiting ring and pull the limiting ring outward, which facilitates the entry and exit of the limiting ring.

[0026] After the dining table board is opened, the positioning plate can be lifted upward with the pin as the center. After the positioning plate is moved out of the positioning groove, the limiting column can move outward along the groove and the positioning column until the limiting column is against the back of the backrest. At this time, the positioning plate can be pressed down to make the positioning plate enter another positioning groove, and the card block on the positioning plate can be inserted into the card slot to clamp the inserted positioning plate. The moved limiting column can be positioned by the positioning plate, and the dining table board can be limited by the limiting column that contacts the backrest, so that after the dining table board is pressed, the dining table board will not be lifted upward, so as to increase the stability of the items on the dining table board.

[0027] When the water cup is needed, the limiting ring can be pulled in a limited position. After the limiting ring is moved out of the hidden groove, the bottom of the supporting assembly will lose its obstruction, so that the supporting plate can rotate downward with the hinge as the center, and the end of the supporting plate close to the limiting ring can rest on the bottom surface of the limiting ring, while the bottom plate can rotate with the hinge as the center, and one end surface of the bottom plate contacts the inner side surface of the supporting plate, so that the bottom plate and the supporting plate are combined to form an "L"-shaped structure. After the water cup is inserted into the limiting ring, the bottom surface of the water cup can be placed on the bottom plate, which can better limit the water cup, avoid the tipping over of the water cup and increase stability.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
