[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific implementation methods.

[0020] The disadvantage of the relatively cumbersome process of adjusting the two leg supports of the prior art examination bed. After careful analysis, the inventor found that the main reason for the above technical problems is that the leg support rod is set in the connecting sleeve, and a locking screw is provided in the connecting sleeve. When the leg support rod needs to be adjusted, the locking screw must be loosened to move the leg support rod up and down. When it is moved to the appropriate position, the leg support rod is fixed by tightening the locking screw. Therefore, the process of adjusting the two leg support rods is relatively cumbersome, and each leg support needs to be operated separately, which undoubtedly increases the complexity of the operation and the time cost. More importantly, due to the lack of a synchronous adjustment mechanism, it is difficult to ensure that the leg supports on both sides are adjusted to a completely consistent height, which may affect the patient's body comfort and the accuracy of the examination. In addition, even the fine-tuning process needs to be performed separately for each leg support, which further increases the workload of medical staff and reduces the efficiency of the inspection. Based on the above analysis, the inventor designed a gynecological examination bed that can adjust the position of the left support leg and the right support leg at the same time, which is relatively simple and trouble-free.

[0021] Embodiment 1:

[0022] like Figure 1 to Figure 2 As shown, a gynecological examination bed includes a bed body 1, a left supporting leg 2 and a right supporting leg 3, the left supporting leg 2 and the right supporting leg 3 are symmetrically installed on both sides of the bed body 1, the left supporting leg 2 includes a first telescopic rod 21 and a left supporting plate 22, one end of the first telescopic rod 21 is connected to the left supporting plate 22, and the other end is connected to the bed body 1, the right supporting leg 3 includes a second telescopic rod 31 and a right supporting plate 32, one end of the second telescopic rod 31 is connected to the right supporting plate 32, and the other end is connected to the bed body 1; a driving mechanism 4 for simultaneously driving the first telescopic rod 21 and the second telescopic rod 31 to extend and retract is provided between the left supporting leg 2 and the right supporting leg 3. The first telescopic rod 21 and the second telescopic rod 31 are both provided with ball grooves, and the left supporting leg 2 and the right supporting leg 3 are both provided with ball heads 25, and the ball heads 25 are rotatably embedded in the ball grooves.

[0023] The driving mechanism 4 includes a screw rod 41, a left movable sleeve 42, a left connecting rod 43, a right connecting rod 44 and a right movable sleeve 45. The screw rod 41 is rotatably mounted on the bed body 1. One end of the left connecting rod 43 is hinged to the first telescopic rod 21, and the other end is hinged to the left movable sleeve 42. One end of the right connecting rod 44 is hinged to the second telescopic rod 31, and the other end is hinged to the right movable sleeve 45. The surface of the screw rod 41 is formed with two threaded areas with opposite thread directions. The left movable sleeve 42 and the right movable sleeve 45 are respectively located in the two threaded areas of the screw rod 41 and are threadedly connected to the screw rod 41. The bed body 1 is provided with a first motor 5 for driving the screw rod 41 to rotate. The screw rod 41 is arranged vertically with the first telescopic rod 21. The first telescopic rod 21 includes a vertical rod 23 and a telescopic sleeve 24. One end of the vertical rod 23 is fixedly connected to the bed body 1, and the telescopic sleeve 24 is slidably sleeved on the other end of the vertical rod 23. The telescopic sleeve 24 is hinged to the left connecting rod 43. The structure of the first telescopic rod 21 is consistent with that of the second telescopic rod 31. The screw rod 41 is rotated clockwise to make the left movable sleeve 42 and the right movable sleeve 45 slide toward the center of the screw rod 41 at the same time, thereby pulling one end of the left connecting rod 43 and one end of the right connecting rod 44 to move toward the center of the screw rod 41, driving the left support plate 22 and the right support plate 32 to move downward at the same time; the screw rod 41 is rotated counterclockwise to make the left movable sleeve 42 and the right movable sleeve 45 slide away from the center of the screw rod 41 at the same time, and at the same time push one end of the left connecting rod 43 and one end of the right connecting rod 44 to move away from the center of the screw rod 41, driving the left support plate 22 and the right support plate 32 to move upward at the same time, so as to achieve the simultaneous upward or downward adjustment of the left support leg 2 and the right support leg 3. Since the first telescopic rod 21, the screw rod 41 and the left connecting rod 43 of the left supporting leg 2 form a stable triangular structure, and the screw rod 41 is threadedly connected to the left movable sleeve 42, the left supporting plate 22 can stably support the patient's left leg and is not prone to accidental movement; since the second telescopic rod 31, the screw rod 41 and the right connecting rod 44 of the right supporting leg 3 form a stable triangular structure, and the screw rod 41 is threadedly connected to the right movable sleeve 45, the right supporting plate 32 can stably support the patient's right leg and is not prone to accidental movement. The screw rod 41 is threadedly connected to the right movable sleeve 45 and the left movable sleeve 42, which is conducive to fine-tuning the positions of the left supporting leg 2 and the right supporting leg 3.

[0024] The left support plate 22 and the right support plate 32 are both L-shaped and have grooves for placing the leg joints. The left support plate 22 and the right support plate 32 are both groove-shaped to simulate the shape of the leg, and the whole simulates the L-shape of the bent leg joints, and the angle between the two surfaces is between 120 degrees and 150 degrees, which improves the comfort of the patient.

[0025] Embodiment 2:

[0026] like Figure 3As shown, the difference between Example 2 and Example 1 lies in the driving mechanism 4, which includes a synchronous belt 46 and two gears 47. The synchronous belt 46 is sleeved on the gears 47 and meshed therewith. One gear 47 is sleeved on the first telescopic rod 21 and fixedly connected therewith, and the other gear 47 is sleeved on the second telescopic rod 31 and fixedly connected therewith. The first telescopic rod 21 includes a first rotating cylinder and a first lifting rod. One end of the first lifting rod is inserted into the first rotating cylinder and threadedly connected therewith, and the other end is connected to the left support plate 22. The first rotating cylinder is rotatably arranged on the bed body 1, and a gear 47 is connected to the first rotating cylinder. The second telescopic rod 31 includes a second rotating cylinder 33 and a second lifting rod 34. One end of the second lifting rod 34 is inserted into the second rotating cylinder 33 and threadedly connected therewith, and the other end is connected to the right support plate 32. The bed body 1 is provided with a second motor 6 for driving the second rotating cylinder 33 to rotate, and another gear 47 is connected to the second rotating cylinder 33. The second motor 6 drives the second rotating cylinder 33 to rotate clockwise. Since the second rotating cylinder 33 is threadedly connected to the second lifting rod 34, the second lifting rod 34 is driven to move upward. At the same time, due to the rotation of the synchronous belt 46, the first rotating cylinder is also driven to rotate clockwise, thereby driving the first lifting rod to move upward. The second motor 6 drives the second rotating cylinder 33 to rotate counterclockwise, driving the second lifting rod 34 to move downward. At the same time, it drives the first rotating cylinder to rotate counterclockwise, thereby driving the first lifting rod to move downward. The second motor 6 is designed to drive the second rotating cylinder 33 instead of manually rotating the second rotating cylinder 33, and combined with the synchronous belt 46, it not only reduces the workload of medical staff, but also realizes the simultaneous upward or downward adjustment of the left supporting leg 2 and the right supporting leg 3.

[0027] Among them, a connecting rod 7 is provided between the first telescopic rod 21 and the second telescopic rod 31, one end of the connecting rod 7 is fixedly connected to the first telescopic rod 21, and the other end is fixedly connected to the second telescopic rod 31. The connecting rod 7 can not only increase the structural strength of the left supporting leg 2 and the right supporting leg 3, so that they cannot be deformed, but also when the second rotating cylinder 33 and the first rotating cylinder rotate, the first telescopic rod 21 and the second telescopic rod 31 will not rotate with them, so as to ensure that the left supporting leg 2 and the right supporting leg 3 can be adjusted upward or downward at the same time.

[0028] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the protection scope of the present invention.
