[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] See attached Figure 1-6 As shown, a gynecological examination bed includes a bearing plate 1 fixed on a lifting seat, a control host is installed on the bearing plate 1, and the control host is connected to a power supply;

[0021] A hydraulic cylinder 3 electrically connected to the control host is also mounted on the bearing plate 1, and the bottom of the hydraulic cylinder 3 is rotatably connected to the bearing plate 1, and the output end of the hydraulic cylinder 3 is rotatably connected to the back plate 4;

[0022] See attached Figure 1-3 A hip plate 5 for patients to sit or lie is also installed on the top of the carrying plate 1, and the hip plate 5 is movably connected to the back plate 4, and armrest boxes 2 are installed on both sides of the hip plate 5. The armrest boxes 2 are hollow, and the bottom of the armrest boxes is fixedly connected to the carrying plate 1;

[0023] See attached Figure 2-6 The two armrest boxes 2 are both equipped with flexible leg supports 15 through a leg posture adjustment mechanism, and the leg posture adjustment mechanism is electrically connected to the control host. When examining a patient, the patient can sit on the hip board 5, with his legs respectively located on the inner side of the flexible leg support 15, and the patient's legs can be automatically lifted through the leg posture adjustment mechanism;

[0024] The lifting seat and the control host are both existing mature technologies. The lifting seat can adjust the height of the carrying plate 1, and the control host can manage the operation of the hydraulic cylinder 3 and the leg posture adjustment mechanism. This specific embodiment will not be described in detail.

[0025] This embodiment will not be described in detail, the core solution of this technical solution lies in the specific structure of the leg posture adjustment mechanism;

[0026] See attached Figure 5 and attached Figure 6, considering that patients have different body shapes, some may have longer or shorter legs, which may cause the distance between the patient's legs and the flexible leg support 15 to not match when the patient sits on the hip board 5. In order to solve this problem, a rectangular column 23 is fixed to the end of the pull rod 14 away from the circular connecting column 22, and a rectangular slot adapted to the rectangular column 23 is opened inside the L-shaped connecting column 20, and the rectangular column 23 is located inside the rectangular slot. In addition, the rectangular column 23 and the L-shaped connecting column 20 have an interference fit;

[0027] When the patient's legs are long or short, resulting in the distance between the legs and the flexible leg support 15 not being suitable when sitting on the hip board 5, the distance between the flexible leg support 15 and the patient's legs can be adjusted by pulling the pull rod 14 to adapt it to the patient's body shape, thereby improving the applicability and comfort of the device;

[0028] See attached Figure 2-6 The leg posture adjustment mechanism includes a support assembly for supporting the flexible leg support 15, a rotation assembly for rotating the support assembly, and a displacement assembly for adjusting the distance between the two flexible leg supports 15;

[0029] The support assembly includes two driving rods 11 rotatably connected to the two armrest boxes 2, and the two driving rods 11 are respectively located inside the two armrest boxes 2, and the outer side of the driving rod 11 is movably connected with a rotating ring 10, and an L-shaped connecting column 20 is fixed to the bottom of the rotating ring 10, and a movable groove adapted to the L-shaped connecting column 20 is opened inside the armrest box 2, and the L-shaped connecting column 20 passes through the inside of the movable groove on the armrest box 2, and a pull rod 14 is installed at one end of the L-shaped connecting column 20 away from the rotating ring 10, and the pull rod 14 is connected to the flexible leg support 15;

[0030] See attached Figure 6 In addition, in order to further improve the patient's leg comfort, a circular connecting column 22 is fixed on the outside of the flexible leg support 15, and a ball is fixed at one end of the circular connecting column 22. A ball groove adapted to the ball is opened inside the pull rod 14, and the ball is located inside the ball groove. Through the arrangement of the ball and the ball groove, a ball joint is formed between the circular connecting column 22 and the pull rod 14, and an interference fit is adopted between the ball and the ball groove. By bending the flexible leg support 15, the ball can move in the ball groove, and the interference fit ensures that the flexible leg support 15 can be locked after the angle is adjusted, so that the angle can be flexibly adjusted when the patient's legs are lifted, thereby further improving the patient's comfort;

[0031] See attached Figure 3-5The rotating assembly includes a driving motor 6 electrically connected to the control host, the driving motor 6 is installed inside one of the armrest boxes 2, the output end of the driving motor 6 is fixedly connected to the armrest box 2 and is rotatably connected with a bidirectional screw 7, the bidirectional screw 7 is located below the hip plate 5 and passes through the inside of the two armrest boxes 2, and the two ends of the bidirectional screw 7 are respectively located inside the two armrest boxes 2, two second bevel gears 21 are fixed to the outside of the bidirectional screw 7, the two second bevel gears 21 are respectively located inside the two armrest boxes 2, and the top of the second bevel gear 21 is meshed and connected with the first bevel gear 16. A threaded rod body 17 is fixed inside the first bevel gear 16;

[0032] In order to support the threaded rod body 17, bearing blocks are rotatably connected to the outer sides of the threaded rod body 17 near both ends through bearings. The bearing blocks are fixedly connected to the armrest box 2. The threaded rod body 17 and the armrest box 2 are rotatably connected through the setting of the bearing blocks. The threaded rod body 17 can be supported by the bearing blocks, which not only improves the weighing force of the threaded rod body 17, but also makes the threaded rod body 17 rotate more smoothly, avoiding displacement caused by the rotation of the threaded rod body 17.

[0033] See attached Figure 3 and attached Figure 4 The outer side of the threaded rod body 17 is threadedly connected to an L-shaped plate 18, and the L-shaped plate 18 is in contact with the inner wall of the armrest box 2. When the threaded rod body 17 rotates, the L-shaped plate 18 can slide on the outer side of the bidirectional screw 7 and the inner wall of the armrest box 2. The bottom of the L-shaped plate 18 is magnetically connected to a lug block 12, and the lug block 12 is fixed to the outer side of the driving rod 11.

[0034] According to the above structure, when examining a patient, the patient can conveniently sit on the top of the hip board 5 and lean on the back board 4. At this time, as the patient sits down, his legs can be placed on the inner sides of the two flexible leg supports 15 without any effort.

[0035] By controlling the main engine to start the hydraulic cylinder 3, the backboard 4 can be driven to adjust the angle. At this time, the patient can switch from a sitting position to a lying position. By controlling the main engine to start the drive motor 6, the bidirectional screw 7 can be rotated, and the bidirectional screw 7 can drive the first bevel gear 16 and the threaded rod body 17 to rotate. The rotation of the threaded rod body 17 allows the L-shaped plate 18 to move outside the threaded rod body 17. At this time, the L-shaped plate 18 moves toward the top of the lug block 12, and during the movement, the L-shaped plate 18 pushes the lug block 12 downward. Due to the contact between the drive rod 11 and the lug block 12, the L-shaped plate 18 can move toward the top of the lug block 12. The armrest box 2 is rotatably connected, so pushing the lug block 12 can rotate the driving rod 11. During this process, the driving rod 11 can drive the flexible leg support 15 to rise through the rotating ring 10, the L-shaped connecting column 20 and the pull rod 14. When the side of the L-shaped plate 18 fits with the side of the lug block 12, a sliding connection is formed between the L-shaped plate 18 and the lug block 12, and no thrust is generated on the lug block 12. Since the patient's legs are placed on the inner side of the flexible leg support 15 in advance, the legs will be automatically lifted along with the flexible leg support 15, thereby realizing automatic lifting of the patient's legs.

[0036] During the above work:

[0037] See attached Figure 4 In order to reduce the wear between the lug block 12 and the L-shaped plate 18, the bottom of the L-shaped plate 18 is set to be circular. The circular shape can reduce the contact area of ​​the L-shaped plate 18 when pressing the lug block 12, thereby reducing the wear between the L-shaped plate 18 and the lug block 12;

[0038] See attached Figure 4 and attached Figure 6 In order to prevent the driving rod 11 from rotating too much, causing the patient's legs to be lifted too high and affecting comfort, a positioning column 13 is fixed to the end of the lug block 12 away from the rotating ring 10, and an arc groove 19 adapted to the positioning column 13 is provided inside the armrest box 2. The positioning column 13 is located inside the arc groove 19. When the lug block 12 rotates, the positioning column 13 moves along the inside of the arc groove 19 from one end to the other. When one side of the lug block 12 fits with one side of the positioning column 13, the positioning column 13 moves from one end of the arc groove 19 to the other end, thereby limiting the maximum rotation angle of the driving rod 11 through the arc groove 19.

[0039] When the inspection is completed and the flexible leg support 15 needs to be reset, the driving motor 6 can be operated again to reset the L-shaped plate 18. In order to reset the lug block 12, magnetic strips are provided on the outer side of the L-shaped plate 18 and the outer side of the lug block 12. The L-shaped plate 18 and the lug block 12 are magnetically connected through the magnetic strips. When the L-shaped plate 18 is reset, the L-shaped plate 18 and the lug block 12 are magnetically connected, and the L-shaped plate 18 can drive the lug block 12 to reset.

[0040] In summary: the utility model enables the patient's legs to be automatically lifted when undergoing examination without additional effort, thereby alleviating the inconvenience and discomfort that the patient may feel during obstetrics and gynecology examinations.

[0041] See attached Figure 4 and attached Figure 5 At the same time, it is necessary to consider that the distance between the two legs of the patient may be too small after the patient lifts his legs, which may affect the examination. Therefore, the leg posture adjustment mechanism also includes a displacement component for adjusting the distance between the two flexible leg supports 15, and the displacement component includes two moving plates 8 located on the outsides of the two second bevel gears 21, respectively, and the two moving plates 8 are respectively threadedly connected to the two ends of the bidirectional screw 7, and a moving ring 9 is fixed to one end of the moving plate 8, and the moving ring 9 is movably connected to the rotating ring 10;

[0042] According to the above structure, when the patient's legs are being lifted, the rotation of the bidirectional screw 7 will also enable the two movable plates 8 to move away from each other, that is, the movable plates 8 will move away from the second bevel gear 21. Therefore, the rotating ring 10 can be driven to move away from the lug block 12 through the movable ring 9. In this process, the two flexible leg supports 15 can be moved away from each other through the L-shaped connecting column 20 and the pull rod 14, and then the distance between the two flexible leg supports 15 can be adjusted. After the distance adjustment is completed, the drive motor 6 stops working, thereby achieving the simultaneous lifting and opening of the patient's legs, which is convenient and labor-saving, thereby improving the overall examination experience.

[0043] During the above work:

[0044] See attached Figure 6 In order to enable the rotating ring 10 to move during the rotation process, a rectangular bar is fixed on the outside of the pull rod 14, and a rectangular positioning groove adapted to the rectangular bar is opened inside the rotating ring 10. The rectangular bar is located in the rectangular positioning groove. Therefore, when the pull rod 14 rotates, the rotating ring 10 is driven to rotate together through the setting of the rectangular positioning groove and the rectangular bar;

[0045] In addition, a positioning ring is fixed on the outside of the rotating ring 10, and an annular groove adapted to the annular limiting ring is opened inside the mobile ring 9, and the positioning ring is located inside the annular groove, so that the rotating ring 10 and the mobile ring 9 are rotatably connected through the positioning ring and the annular groove. When the rotating ring 10 and the mobile ring 9 rotate, they still remain connected. When the mobile plate 8 moves, the positioning ring and the annular groove can drive the rotating ring 10 to move. During the process, the rotating ring 10 can slide on the outside of the driving rod 11 through the rectangular positioning groove and the rectangular bar.

[0046] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified or limited.
