Abstract

The invention discloses a train seat table board, and relates to the field of traffic. The train seat table board comprises a dining table board, a dining board through shaft and dining board supporting arms, wherein the dining table board is connected with the dining board supporting arms through the dining board through shaft, and the dining table board and the dining board supporting arms are in rotatable connection; the dining table board comprises a panel, an inner lining, a bottom board and an aluminum alloy framework, wherein the panel and the bottom board are in up-down symmetrical arrangement, frames of four sides of the panel are protruded downwards to form a downward cavity, and frames of four sides of the bottom board are protruded upwards to form an upward cavity. Compared with a conventional train seat table board, the train seat table board disclosed by the invention has the advantages that the assembly efficiency is improved, the reliability of the table board is improved, the intensity is higher, the bearing capacity is higher, the service life is longer, the weight is lighter, and the self weight of a seat can be reduced.

Example Embodiment

[0016] The present invention will be further described below in conjunction with the drawings.
[0017] Such as Figure 1-4 , A train seat table board, including a dining table board, a dining board through shaft 9 and a dining board support arm 8. The dining table board and the dining board support arm 8 are connected through the dining board through shaft 9, and the dining table board and the dining board support arm 8 are rotatably connected.
[0018] The dining table board includes a panel 1, an inner lining 2, a bottom plate 3 and an aluminum alloy frame 6.
[0019] The panel 1 and the bottom plate 3 are arranged symmetrically up and down and correspond to each other. The four sides of the panel 1 protrude downward to form a downward cavity, and the four sides of the bottom plate 3 protrude upward to form an upward cavity.
[0020] The panel 1 and the inner liner 2 are respectively provided with a cup holder 4, and the edges of the panel 1 and the bottom plate 3 are respectively provided with overlapping connecting surfaces 5. The panel 1 and the bottom plate 3 are respectively provided with arm connection ports 7.
[0021] The frame of the panel 1 is fitted with the frame of the bottom plate 3, the overlapping connecting surfaces 5 of the panel 1 and the bottom plate 3 are attached to each other, the panel 1 corresponds to the arm connection port 7 on the bottom plate 3, and a lining space is formed between the panel 1 and the bottom plate 3. Cavity.
[0022] The inner lining 2 is arranged in the inner lining cavity, and the aluminum alloy frame 6 is sleeved on the inner lining 2. The inner liner 2 is a foamed material body.
[0023] The supporting arm of the dining plate 8 is connected to the arm connecting port 7 of the dining plate through the through shaft 9 of the dining plate, and the two ends of the through shaft 9 of the dining plate are fixed by a screw at each end.
[0024] There is a plastic block 11 on the left and right where the panel 1, the bottom plate 3 and the dining board support arm 8 are connected to increase the friction of the dining board, so that the dining board has resistance when it is put down, and it will not drop immediately.
[0025] A flanging bushing 10 is arranged in the hole 13 at the bottom end of the support arm 8 of the dining plate, and a plastic washer 12 is arranged in the flanging bushing 10. The plastic washer 12 increases the friction of the dining plate and prevents the dining plate from being put down immediately. There is a certain resistance.
[0026] When in use, the panel 1 has a simple structure, only the panel 1, the bottom plate 3, the aluminum alloy frame 6, and the inner lining 2 are connected, which not only improves the assembly efficiency and the reliability of the table, but also the internal aluminum alloy frame 6 and the inner lining 2. , So that the product has higher strength, stronger bearing capacity and longer service life. At the same time, the aluminum alloy frame 6 is light in weight, which can reduce the weight of the seat itself.
