When the rotating rod 15 drives the first cam 17 and the first blocking rod 25 to rotate, the first blocking rod 25 can drive the second cam 26 to rotate. When the first blocking lever 25 drives the second cam 26 to rotate, the second blocking lever 27 can drive the connecting rod 24 and the arc plate 11 to rotate. During the rotation of the arc plate 11, the opposite ends of the middle plate 6 and the side plate 8 can be driven to move upward.

A protective pad 7 is fixed on the side plates 8 , and the protective pad 7 is fixed on the upper end of the side plate 8 away from the middle plate 6 .

In this embodiment, the ultrasonic inspection instrument 9 is placed on one side of the device. The pregnant woman lies on the side board 8 or the middle board 6, and the ultrasonic examination instrument 9 is used to examine the pregnant woman.

Referring to Figures 2, 6 and 8, when it is necessary to adjust the pregnant woman's position so that she lies on her left side, the pregnant woman lies on the middle board 6. The motor 3 connected to the right rotating rod 15 is started, so that the right motor 3 drives the right rotating rod 15 to rotate. When the rotating lever 15 on the right side rotates, the first cam 17 and the first blocking lever 25 are driven to rotate. When the first blocking lever 25 contacts the second cam 26, the first cam 17, the first blocking lever 25, the second cam 26 and the second blocking lever 27 rotate synchronously. When the second blocking rod 27 contacts the connecting rod 24, the first cam 17, the first blocking rod 25, the second cam 26, the second blocking rod 27, the connecting rod 24 and the arc plate 11 rotate.

During the rotation of the arc plate 11, the opposite ends of the right side plate 8 and the middle plate 6 can be driven to move upward. During the upward movement of the opposite ends of the right side panel 8 and the middle panel 6, the middle panel 6 and the right side panel 8 are folded, and the first connecting column 2 on the right side of the middle panel 6 and the right side panel 8. The second connecting column 20 close to the middle plate 6 exits from the first notch 13. At the same time, the opposite ends of the middle plate 6 and the left side plate 8 rotate relative to each other.

During the upward movement of the opposite ends of the right side panel 8 and the middle panel 6, the pregnant woman lying on the middle panel 6 assumes a position of lying on her left side.

During the upward movement of the opposite ends of the right side panel 8 and the middle panel 6, under the action of the gravity of the pregnant woman, the right side panel 8 wraps around the second connecting column 20 located in the second notch 19 on the right side. Rotate, and the left side plate 8 remains parallel to the horizontal plane and moves to the right direction. When the left side plate 8 remains parallel to the horizontal plane and moves to the right, the second spring 23 on the left is compressed, and the first spring 18 on the left gradually restores.

By providing the second spring 23, during the restoration process of the side plate 8, the elastic force of the second spring 23 can assist the restoration of the side plate 8 on one side of the second spring 23.

When the side plate 8 and the middle plate 6 are horizontal, the first spring 18 is compressed. When the side panel 8 and the middle panel 6 are folded, the elastic force of the first spring 18 can assist the folding of the side panel 8 and the middle panel 6 on one side of the first spring 18 .

When the left side panel 8 moves to the right, the left side pad 7 is close to the pregnant woman. After the pregnant woman lies on the left side, the pregnant woman can hold the left side pad 7 to prevent the pregnant woman from falling in the middle of the tilt. The board 6 slides onto the side board 8 on the left side, enabling the pregnant woman to maintain a side-lying position. Convenient for ultrasound examination of pregnant women. At the same time, it is convenient for pregnant women to maintain a side-lying position for enough time to conduct a complete ultrasound examination.

In the same way, when it is necessary to make the pregnant woman lie down on the right side, the motor 3 connected to the left rotating rod 15 is started, so that the left motor 3 drives the left rotating rod 15 to rotate, thereby causing the left side panel to rotate. 8 and the end opposite to the middle plate 6 moves upward. After the opposite ends of the left side panel 8 and the middle panel 6 move upward, the pregnant woman's right-lying posture can be adjusted.

The rotation angle of the arc-shaped plate 11 can be controlled to change the inclination angle of the middle plate 6, thereby adjusting the angle of the pregnant woman lying on her side to facilitate ultrasound examination of the pregnant woman. A pregnant woman lying on her side can hold the pad 7 and lean her back on the inclined middle plate 6, which can facilitate the pregnant woman to maintain the position of lying on her side until the ultrasound examination is completed.

Embodiment 2

On the basis of Embodiment 1, as shown in Figures 2, 3 and 6, the hinged middle panel 6 and the side panels 8 are connected through a plurality of auxiliary folding components. The auxiliary folding assembly includes a second connecting plate 22 fixed on the lower end of the side panel 8 and a first connecting plate 14 fixed on the lower end of the middle panel 6 . The lower ends of the first connecting plate 14 and the second connecting plate 22 are connected through an elastic pull cord 12, and the pull cord 12 passes through the through slot 16 on the rotating rod 15 on one side thereof.

The second connecting plate 22 is fixed to the lower end of the side plate 8 away from the middle plate 6 . The second connecting plate 22 and the first connecting plate 14 connected by the pull cord 12 are arranged symmetrically according to the axis of the rotating rod 15 through which the pull cord 12 penetrates.

When the rotating rod 15 is rotated to fold the middle panel 6 and the side panels 8 , the rotating rod 15 is rotated to wrap around the elastic drawstring 12 passing through the rotating rod 15 . When the opposite ends of the middle panel 6 and the side panels 8 are pushed up by the arc-shaped plate 11, the hinged middle panel 6 and the side panels 8 can be assisted to fold under the pulling force of the drawstring 12.

A second cam 26 and a second blocking rod 27 are provided on the rotating rod 15 between the first cam 17 and the connecting rod 24. The connecting rod 24 and the arc plate 11 are driven to rotate only after the rotating rod 15 rotates for a set number of turns. It is convenient for the rotating rod 15 to wrap the drawstring 12 to a sufficient length, so that the drawstring 12 can exert sufficient pulling force on the second connecting plate 22 and the first connecting plate 14 before the side panels 8 and the middle panel 6 are folded, thereby assisting the side panels. 8 and the folding movement of the middle panel 6.
