[0028] Reference Figure 1-4 The utility model provides an embodiment: a folding bed frame that is easy to adjust, including a fixed bed board 1, both sides of the fixed bed board 1 are fixedly connected with fixed cross bars 5, the interiors of the two groups of fixed bed boards 1 are slidably connected with sliding bed boards 10, one end of the sliding bed board 10 is fixedly connected with two groups of sliding cross bars 11, and the sliding cross bars 11 are respectively located on both sides of the sliding bed board 10, and the sliding cross bars 11 are all slidably connected to the interior of the fixed cross bars 5, the middle parts of the opposite ends of the two groups of sliding bed boards 10 are rotatably connected with the first rotating shaft 8, and both ends of the first rotating shaft 8 pass through the fixed cross bars 5 and the sliding cross bars 11, and the first rotating shaft 8 is slidably connected to the opposite ends of the four groups of fixed cross bars 5.

[0029] The surfaces of the two groups of fixed bed boards 1 are provided with a first mattress 2, and the upper surfaces of the two groups of first mattresses 2 are provided with a second mattress 3, and one end of the second mattress 3 is provided with a protruding end. The thickness of the second mattress 3 is greater than the thickness of the first mattress 2, the upper ends of the second legs 6 are fixedly connected to the headboard 14, and the lower ends of the headboard 14 are fixedly connected to the support plate. The middle parts of the opposite sides of the two groups of second legs 6 are fixedly connected to the fixed plate 9, and the second rotating plates 12 are rotatably connected at both ends of the second rotating shaft 13. The lower ends of the second rotating plates 12 are fixedly connected to the second legs 6. The ends of the two groups of fixed bed boards 1 away from each other are rotatably connected to the second rotating shaft 13, and the second rotating shaft 13 passes through one end of the two groups of fixed cross bars 5. The lower end of the first rotating plate 7 is fixedly connected to the first leg 4, and the opposite sides of the middle parts of the two groups of first legs 4 are fixedly connected to the fixed plate 9. The two ends of the two groups of first rotating shafts 8 are rotatably connected to the first rotating plate 7, and the two groups of first rotating shafts 8 are respectively located on both sides of the first rotating plate 7.

[0030] Working principle: When in use, rotate the second leg 6 so that the second leg 6 rotates around the second rotation axis 13, so that the second leg 6 is close to the lower surface of the fixed cross bar 5, and the two groups of second legs 6 are close to the lower surface of the fixed cross bar 5. By rotating the fixed bed board 1, the two groups of fixed bed boards 1 are rotated around the first rotation axis 8, so that the lower surfaces of the two groups of fixed bed boards 1 are folded together, so that the lower surfaces of the two groups of fixed bed boards 1 clamp the first leg 4, and at the same time, the lower surface of the fixed bed board 1 clamps the second leg 6.
