Embodiment 1
[0053] See figure 1 .
[0054] figure 1 This embodiment 1 provides a structural schematic diagram of a rotary folding table with a rotatable table top and a two-layer board.
[0055] See Figure 1-15 As shown, the folding table in this embodiment mainly includes four uprights 1011, 1012, 1013, and 1014. At least one pair of supporting beams is arranged between the uprights 1011, and the four uprights. Each pair of supporting beams consists of two horizontally opposed supporting beams. (First supporting beam, second beam). For example, in this embodiment, the supporting beam 1021 and the horizontally opposite supporting beam 1022 constitute a supporting beam pair.
[0056] Among them, the supporting beams 1021 and 1022 are respectively formed by three sections of sub beams joined by hinges. In order to ensure that the folded thickness of the folding frame is sufficiently thin, in this embodiment, the length of the sub-beam located in the middle can be set to be less than the thickne...
Embodiment 2
[0076] See Figure 15-26 As shown, the folding frame of this embodiment is relatively Figure 1-14 The structure shown, the difference is as follows:
[0077] The layer 203 (and / or the support beams 2021 and 2022) in this embodiment can be a whole piece of material that can be bent upright, and similarly, the support beams 2011 and 2022 are all a piece of material that can be bent horizontally.
[0078] During the research of the present embodiment, the inventor found that the use of thinner or softer materials, while the bendable material has poor bearing strength, and if the thickness is increased, the material cost will be higher. And the thicker the material used, the thicker the folding structure of the folding table is not compact enough to be transported.
[0079] However, in this embodiment, arranging connecting rods 2041 and 2042 on the back of the laminate 203 can further increase the supporting and bearing functions of the laminate 203 and the supporting beams 2021 and 20...
