The first mounting plate 10 is used for being connected with the table board 200, and the first mounting plate 10 is provided with a first groove 1114; the second mounting plate 20 is used for fixed mounting, the second mounting plate 20 is rotatably connected with the first mounting plate 10, the second mounting plate 20 is provided with a second groove 2114 which is in alignment communication with the groove 14, and the groove wall of the second groove 2114 is provided with a sliding guide groove 211; the support plate 30 is disposed in the first recess 1114 and the second recess 2114, a first end of the support plate 30 is rotatably connected to a groove wall of the first recess 1114, and a second end of the support plate 30 is slidably disposed in the sliding guide groove 211; when the second end of the support plate 30 abuts against the first end of the sliding guide groove 211, the first mounting plate 10, the second mounting plate 20 and the support plate 30 are located in the same plane, and the folding mechanism 100 for a desk board is in a folded state; when the second end of the supporting plate 30 abuts against the second end of the sliding guide groove 211, the first mounting plate 10, the second mounting plate 20 and the supporting plate 30 are arranged in a triangular structure, and the turnover folding mechanism 100 for the table is in an unfolded use state.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: when the turnover folding mechanism 100 for the table board is in the folded state, the second end of the support plate 30 slides to one end of the sliding guide groove 211, at this time, the support plate 30, the first mounting plate 10 and the second mounting plate 20 are folded and are in the same plane, and because the support plate 30 is located in the first groove 1114 and the second groove 2114, the folded turnover folding mechanism has a small volume and occupies a small space; when the table 200 needs to be used, the first mounting plate 10 rotates and unfolds relative to the second mounting plate 20, meanwhile, the first end of the supporting plate 30 rotates relative to the first mounting plate 10, the second end of the supporting plate 30 slides along the sliding guide groove 211 until the other end of the sliding guide groove 211 is abutted, so that the first mounting plate 10, the supporting plate 30 and the second mounting plate 20 can be unfolded completely into a triangular structure to form stable support for the table 200, the structure of the whole overturning and folding mechanism is simple, and the stability is good.

In some embodiments, the flip-folding mechanism 100 for a table further includes a first rotating shaft 40, and the first end of the supporting plate 30 is rotatably disposed on a groove wall of the first recess 1114 through the first rotating shaft 40. The first rotating shaft 40 can provide a rotational degree of freedom for the support plate 30 to rotate relative to the first mounting plate 10, so that the support plate 30 can be folded or unfolded with the first mounting plate 10.
