Embodiment 2
[0031] Such as Figure 1 to Figure 3 As shown, this embodiment is a further optimization of Embodiment 1. In this embodiment, the fixing parts 5 arranged at intervals at the inner bottom of the rectangular frame 4 include a circular ring and a positioning piece connected to the circular ring. The fixing part 5 is connected to the inner bottom of the rectangular frame 4 through the positioning piece. One end connected to the piece 5 is provided with a hook 10, and the hook 10 is mated and connected with the ring. The fixing method that the hook 10 cooperates with the circular ring has a simple structure, and the hook 10 generally cannot fall off the ring, so the fixing is reliable and easy to use. The hook 10 is rotationally connected with the second connecting rod 7 to facilitate adjustment of the direction of the hook 10 so that the hook 10 can be hooked into the ring with the maximum depth to ensure the reliability of fixing.
Embodiment 3
[0033] Such as Figure 1 to Figure 3 As shown, this embodiment is a further optimization of the foregoing embodiments. In this embodiment, there are two first connecting rods 6 and two second connecting rods 7 arranged on the bottom surface of the table board 3, the projection of the first connecting rod 6 on the bottom surface of the table board 3 is parallel to the longitudinal direction of the bed frame, and the second connecting rod 7 Rotate and hinge with the bottom surface of the table board 3 . The second connecting rod 7 is used to adjust the height of the table board 3, so the length of the second connecting rod 7 should be greater than the length of the first connecting rod 6, and in order to have a larger use area, the table board 3 is designed to be rectangular by the size of the bed frame 2 , the second connecting rod 7 is designed to be rotated so that the second connecting rod 7 has enough space for placement.
