[0033] The first bed board 1 and the second bed board 2, with a bed frame 3 sleeved outside the first bed board 1 and the second bed board 2, and the first bed board 1 is fixedly connected to the bed frame 3;

[0034] The first rotating shaft 4 is embedded inside the bed frame 3. The first rotating shaft 4 is fixedly embedded inside the second bed board 2. Cavities 1 are provided on the inner walls of the front and rear sides of the bed frame 3. Cavities 2 are provided at the tops of the two cavities 1. The first rotating shaft 4 penetrates through the two cavities 2. Inside the two cavities 1, there is a moving plate 5. Two toothed plates 6 are fixedly connected to the top of the moving plate 5. Two gears 7 meshingly connected to the tops of the two toothed plates 6 are provided. The two gears 7 are fixedly sleeved outside the first rotating shaft 4;

[0035] The screw rod 8 is embedded inside the bed frame 3. The screw rod 8 penetrates through the moving plate 5 and is threadedly connected thereto;

[0036] The rotating block 9 is fixedly sleeved outside the screw rod 8. A plurality of card slots evenly distributed in a circular shape are provided on the rotating block 9. A through groove is provided on one side of the bed frame 3. A fixing pin 10 is provided inside the through groove. The fixing pin 10 penetrates through one of the card slots;

[0037] The second bed board 2 is slidably connected to the bed frame 3. The two gears 7 are respectively located inside the two cavities 2. The moving plate 5 is slidably connected to the cavity 1. The fixing pin 10 is slidably connected to the through groove and the card slot;

[0038] In this embodiment, the screw rod 8 is rotated to move the moving plate 5 and the two toothed plates 6, and then the two gears 7 and the first rotating shaft 4 are rotated, so as to fold the second bed board 2;

[0039] Among them, in order to achieve the purpose of rotating the screw rod 8, the following technical solution is adopted in this device: One end of the screw rod 8 is fixedly connected with a knob 11. Rotating the knob 11 can rotate the screw rod 8;

[0040] Among them, in order to achieve the purpose of the stable movement of the moving plate 5, the following technical solution is adopted in this device: Two guide rods 13 are fixedly connected inside the bed frame 3. The two guide rods 13 are respectively located on the front and rear sides of the screw rod 8. The two guide rods 13 penetrate through the moving plate 5 and are slidably connected thereto. The guide rods 13 can make the moving plate 5 move stably;

[0041] Among them, in order to achieve the purpose of preventing the second bed board 2 from being stuck with the first bed board 1, the following technical solution is adopted in this device: Two protective frames 14 are fixedly connected to the top of the bed frame 3. The two protective frames 14 are respectively sleeved outside the two gears 7. A flexible rubber pad 15 is fixedly connected between the first bed board 1 and the second bed board 2. The design of the flexible rubber pad 15 can prevent the second bed board 2 from being stuck with the first bed board 1;

[0042] Among them, in order to achieve the purpose of support, the following technical solution is adopted in this device: Support legs 16 are fixedly connected to the inner walls of the front and rear sides of the bed frame 3. The support legs 16 can support the device;

[0043] Among them, in order to achieve the purpose of reducing wear, the present device is implemented by the following technical solution: the first rotating shaft 4 is connected to the bed frame 3 through a bearing, and the screw rod 8 is connected to the bed frame 3 through a bearing. The connection through the bearing can reduce wear.

[0044] The use process of the present utility model is as follows: when a patient needs to sit on this medical bed, the staff member pulls out the fixing pin 10 from the card slot and the through slot with one hand, and then rotates the knob 11 with the other hand, so that the screw rod 8 can be rotated. When the screw rod 8 rotates, the moving plate 5 and the two toothed plates 6 can move to the left. When the two toothed plates 6 move, the two gears 7 can be rotated. The rotation of the two gears 7 drives the rotation of the first rotating shaft 4. When the first rotating shaft 4 rotates, the second bed board 2 can be folded to become inclined. After the second bed board 2 is adjusted, the fixing pin 10 is inserted back into the through slot, and at the same time, the fixing pin 10 will be stuck in one of the card slots. When the through slot is not aligned with the card slot on the rotating block 9, the screw rod 8 can be rotated to align the through slot with any one of the card slots, and then the patient can sit and lean against the second bed board 2;

[0045] Since the moving plate 5 is threadedly connected to the screw rod 8, and the threaded connection belongs to a self-locking structure, when sitting and leaning against the second bed board 2, there will be no phenomenon that the first rotating shaft 4 and the gear 7 rotate in the reverse direction, resulting in the toothed plate 6 and the moving plate 5 moving to the right, and thus there will be no phenomenon that the screw rod 8 rotates in the reverse direction. At the same time, the rotating block 9, the card slot and the fixing pin 10 are designed. By embedding the fixing pin 10 in the card slot, the rotating block 9 can be restricted from moving, and the rotating block 9 is fixedly sleeved outside the screw rod 8, so that the screw rod 8 can be restricted from rotating. In cooperation with the threaded connection, the present device has an anti-folding mechanism, and the second bed board 2 can be prevented from flipping back during sitting and leaning.

[0046] The above is only a preferred embodiment of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model belongs to the scope protected by the present utility model.
