The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. 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 and Figure 3 As shown, a lightweight dining table board with a backrest of the utility model comprises a table board, which is composed of a fixed plate 1 and an adjusting plate 3. A groove 2 is provided on the surface of the fixed plate 1, and the adjusting plate 3 is movably arranged in the groove 2. An adjusting mechanism for driving the adjusting plate 3 to move is installed on one side of the fixed plate 1. Rubber layers 7 are installed on the opposite surfaces of the adjusting plate 3 and the groove 2. Slots are provided at both ends of the adjusting plate 3, and L-shaped plates 12 are provided in the slots. An absorbent cloth 6 is placed on the surface of the adjusting plate 3, and both ends of the absorbent cloth 6 are bent and extended to between the L-shaped plate 12 and the adjusting plate 3, and are both pressed and fixed by the L-shaped plate 12.

[0021] In this embodiment, a plurality of slide grooves 4 are provided on the bottom surface of the groove 2 , and slide bars 5 are installed on the bottom surface of the adjustment plate 3 facing the slide grooves 4 , and the slide bars 5 are slidably disposed in the slide grooves 4 .

[0022] In this embodiment, the adjustment mechanism includes a screw 8, a sealed bearing and a handwheel 9. One end of the adjustment plate 3 is provided with a screw hole penetrating the rubber layer 7, and one side of the fixed plate 1 is provided with a mounting hole penetrating the rubber layer 7 opposite to the screw hole. The sealed bearing is installed in the mounting hole, and the screw 8 is installed in the inner ring of the sealed bearing. One end of the screw 8 is threadedly connected to the screw hole, and the other end is fixedly connected to the handwheel 9.

[0023] In this embodiment, the other end of the adjustment plate 3 is provided with a positioning hole that passes through the rubber layer 7, and a positioning rod 11 is provided in the positioning hole. One end of the positioning rod 11 passes through the positioning hole and is installed on the fixed plate 1, thereby increasing the positioning effect of the adjustment plate and avoiding the adjustment plate from warping upward, thereby ensuring the stability of the adjustment plate when moving.

[0024] In this embodiment, the top surfaces of the fixed plate 1 and the adjusting plate 3 are arranged flush with each other, so that when the adjusting plates are brought together and abut against the fixed plates, a flat table top can be formed.

[0025] In this embodiment, both ends of the fixing plate 1 are provided with connecting shafts 10 connected to the backrest.

[0026] In this embodiment, a plurality of compression springs are installed on one end surface of the L-shaped plate 12 located inside the slot, and the other end of the compression springs are installed on the inner wall surface of the slot. The compression springs can drive the L-shaped plate to move inward to complete the clamping and fixing of the absorbent cloth.

[0027] When in use, the screw rod can be rotated by the hand wheel, and the rotation of the screw rod drives the adjustment plate, so that the adjustment plate moves inward or outward along the slide groove and the positioning rod, so that the size of the table top can be quickly adjusted, which increases adaptability;

[0028] Among them, when in use, cups, mobile phones and other items that need to be fixed can be placed in the groove. After rotating the hand wheel, the adjustment plate can be driven to move inward. During the process of moving closer, the items can be clamped and fixed, thereby ensuring the stability of the items.

[0029] When in use, the L-shaped plate can be pulled outward to open the L-shaped plate and the adjusting plate. At this time, the absorbent cloth can be placed on the adjusting plate, and both ends of the absorbent cloth can be inserted into the gap between the L-shaped plate and the adjusting plate. After the L-shaped plate is released, the L-shaped plate can be pulled inward by the rebound of the compression spring, so that the L-shaped plate can clamp and fix the absorbent cloth. The absorbent cloth can absorb water from fruits placed on the adjusting plate and water splashed from instant noodles, thereby better ensuring the hygiene and safety of the high-speed rail.

[0030] 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.
