[0017] 1. A body position adjustment device for gynecological and obstetric ultrasound examination provided by the present invention is connected to a base frame, a motor, a body position adjustment component and a protection component. The body position adjustment component includes a body plate rotatably connected to the base plate, and also includes a first lifting component for adjusting the angle between the body plate and the base plate. The angle between the body plate and the base plate can be controlled by controlling the lifting state of the first lifting component; the protection component includes a protection plate slidably arranged on the base plate, and also includes a second lifting component for adjusting the height of the protection plate relative to the base plate. The height of the protection plate relative to the base plate can be controlled by controlling the lifting state of the second lifting component; the two (the first lifting component and the second lifting component) are connected to the motor through a transmission component, so that the two The lifting and lowering states are consistent, that is, when the first lifting component rises, the second lifting component also rises. On the contrary, when the first lifting component descends, the second lifting component also descends. When a pregnant woman uses the body position adjustment device, she lies on the base plate with her body placed on the body plate. When turning over or adjusting the body position according to the needs of the ultrasound examination, the first lifting component is controlled to rise by controlling the operation of the motor, and the body plate rotates relative to the base plate, thereby assisting the pregnant woman to turn over or adjust the body position. In this process, the second lifting component also rises, and the protective plate rises relative to the base plate. The body position adjustment component and the protective component are respectively arranged on opposite sides of the base plate, that is, the raised protective plate is on the side where the pregnant woman's body is tilted downward, thereby protecting the pregnant woman's body.

[0018] Wherein, the transmission assembly includes a main shaft and a bevel gear set, the main shaft is fixedly connected to the output shaft of the motor, the bevel gear set includes a first active bevel gear, a second active bevel gear, a first driven bevel gear and a second driven bevel gear, the first active bevel gear and the second active bevel gear are fixedly connected to the main shaft, and the first driven bevel gear and the second driven bevel gear are respectively fixedly connected to the input ends of the first lifting assembly and the second lifting assembly. When the motor is started, the main shaft rotates with the rotation of the motor output shaft, the first active bevel gear and the second active bevel gear rotate with the rotation of the main shaft, and the first driven bevel gear and the second driven bevel gear rotate under the action of the first active bevel gear and the second active bevel gear, respectively, so as to control the lifting and lowering movement of the first lifting assembly and the second lifting assembly; the transmission is realized by using the shaft, that is, the bevel gear set, and the transmission has fast response and high precision. By controlling the operation of the motor, the rotation angle of the body plate relative to the base plate can be accurately controlled, and the body position angle of the pregnant woman can be accurately adjusted, which is beneficial to improving the accuracy of diagnosis;

[0019] The first lifting component includes a lead screw, and the first driven bevel gear is fixedly connected to the lead screw. When the motor operates, the lead screw rotates under the action of the main shaft and the bevel gear set (the first driving bevel gear and the first driven bevel gear).

One end of the buttocks plate is rotatably connected to the base plate, and the other end of the buttocks plate is connected to a third connecting member and a third lifting assembly. By controlling the lifting of the third lifting assembly, the angle between the buttocks plate and the base plate can be controlled to adapt to different position requirements and facilitate the maintenance of a specific position. Both ends of the buttocks plate are connected to two third connecting members and two third lifting assemblies. By controlling the lifting states / heights of the two third lifting assemblies, the relative horizontal height of the buttocks plate (the lifting states of the two third lifting assemblies are the same, and the horizontal height of the buttocks plate can be higher or lower than the horizontal height of the base plate) and the angle with the base plate (the lifting devices of the two third lifting assemblies are different, and the buttocks plate tilts towards the base plate or away from the base plate) can be adjusted. By reducing the horizontal height of the buttocks plate, it can assist the pregnant woman to sit on and / or lie on the upper surface of the base plate of the position adjustment device, improving the convenience of use and expanding the applicable range of the device. By adjusting the angle between the buttocks plate and the base plate, it is convenient to achieve various position examinations and position maintenance. The third lifting assembly is selected as an electric telescopic rod, which has reliable functions and is convenient for operation and control.

[0023] 4. A position adjustment device for obstetrics and gynecology ultrasound examination provided by the present invention further includes a head plate.

Among them, the linkage assembly includes a groove body, a first linkage arm and a second linkage arm. The groove body is slidably connected to a linkage block. Two ends of the first linkage arm are respectively rotatably connected to the third lifting assembly and the linkage block, and two ends of the second linkage arm are respectively rotatably connected to the head plate and the linkage block, so that the angle between the head plate and the base plate is adjusted as the third lifting assembly operates. That is, when the angle height or angle of the buttocks plate changes, the angle of the head plate relative to the base plate changes accordingly, so as to adapt to different position requirements and different position maintenance. Specifically, when the third lifting assembly descends, the linkage block moves towards the side close to the third lifting assembly, and the head plate rotates downward relative to the base plate under the action of the second linkage arm; conversely, when the third lifting assembly ascends, the linkage block moves towards the side away from the third lifting assembly, and the head plate rotates upward relative to the base plate under the action of the second linkage arm.
