[0004] In the above-mentioned prior art, in order to facilitate critically ill patients to get on and off the bed, an auxiliary device is set up, which drives the gear to rotate through a motor, and meshing tooth plates are set on both sides of the gear. When the tooth plate moves to both sides, one end pushes the linkage block to move horizontally, thereby controlling the inclined hinge rod at the upper end to lift or drag down the connecting plate from the lower side. The lifting and lowering of the connecting plate corresponds to the height of the bed. However, since the maintenance of the height of the bed depends on the motor, there is a large load at the connection between the motor output shaft and the motor during long-term use. Moreover, for doctors working in fixed places, the height required for inspection of each bed set at each inspection equipment will not change much. In order to eliminate the defects in the prior art and improve the efficiency of bed height adjustment, we propose a medical inspection auxiliary device. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The figure shows a preferred embodiment of the utility model, a medical examination auxiliary device, including a base 1, a bed 2 is arranged on the upper side of the base 1; a lifting mechanism 3 for changing the height of the bed 2 is arranged between the base 1 and the bed 2, and one end of the lifting mechanism 3 is connected to a control mechanism 4, a positioning mechanism 5 and a reset mechanism 6.

[0022] Specifically, the lifting mechanism 3 includes a threaded barrel 7, which is rotatably connected to the inside of the base 1, and a threaded column 8 is threadedly connected to the inner wall of the threaded barrel 7 near the upper end, and a gear 9 is fixedly connected to the bottom of the threaded barrel 7. The outer wall of the gear 9 is meshed with a toothed plate 10, and the toothed plate 10 is slidably connected to the bottom of the inner wall of the base 1; after the toothed plate 10 moves, it drives the gear 9 and the threaded barrel 7 to rotate in a meshing manner, so that the bed 2 is constrained by the guide barrel 21 and controlled by the threaded column 8 to change the height vertically. It should be noted that by controlling the gear ratio of the gear teeth between the gear 9 and the toothed plate 10, the toothed plate 10 can complete a large adjustment of the height of the bed 2 without moving it too long.

[0023] On the basis of the above scheme, the control mechanism 4 includes a support shaft 11, which is fixedly connected to the bottom of the base 1. The outer wall of the support shaft 11 is rotatably connected to a push handle 12. The push handle 12 is slidably connected to a movable rod 13 on the side close to the tooth plate 10. One end of the movable rod 13 is rotatably connected to the bottom of the tooth plate 10. It can be understood that the support shaft 11 is close to the tooth plate 10. In this way, the tooth plate 10 can be pushed to move in the base 1 with the help of the movable rod 13 by gently pushing the push handle 12. The push handle 12 is arranged at the bottom of the base 1, which reduces the risk of being touched without reason to avoid affecting the inspection.

[0024] Among them, the positioning mechanism 5 includes a screw barrel 14, which is rotatably connected to the outer wall of the base 1, and the inner wall of the screw barrel 14 is threadedly connected to a screw rod 15, and one end of the screw rod 15 is fixedly connected to a stop block 16; after rotating the screw barrel 14, the screw rod 15 is controlled to move laterally in the base 1, and then the moving distance of the tooth plate 10 is limited by the stop block 16, and the maximum rising height of the bed 2 is limited, so that the bed set at different locations can be quickly adjusted to the required height without excessive movement, and by changing the position of the stop block 16, the bed height can be adapted to the bed height required by the physician for the examination item.

[0025] On the basis of the above scheme, the reset mechanism 6 includes a positioning plate 17, which is installed on the bottom of the inner wall of the base 1 by bolts. The outer wall of the positioning plate 17 is fixedly connected with a spring 18, and the other end of the spring 18 is fixedly connected with a tooth plate 10. A plurality of rows of positioning holes 19 are provided at the bottom of the inner wall of the base 1; the spring 18 can push the tooth plate 10 to move toward the side close to the stop block 16. When the patient comes, just gently push the push handle 12 to control the bed 2 to descend. After releasing the push handle 12, the spring 18 pushes the bed 2 to quickly reset to the required height for the examination item. It should be added that when the positioning plate 17 is installed at different positioning holes 19, the thrust can be adjusted when the spring 18 pushes the tooth plate 10 to stop at the stop block 16 to extend the service life of the spring 18.

[0026] The bottom of the inner wall of the base 1 is provided with a through opening 20 , and the length of the opening 20 is adapted to the movable path of the connection between the tooth plate 10 and the movable rod 13 .

[0027] To make the structure more stable, guide cylinders 21 are fixedly installed at both ends of the inner wall of the base 1 to prevent the bed 2 from rotating under the action of the threaded column 8 , and the movable ends of the guide cylinders 21 are fixedly connected to the bottom of the bed 2 .

[0028] In this embodiment, when the patient comes, it is only necessary to gently push the push handle 12 to push the toothed plate 10 to move in the base 1 with the help of the movable rod 13. After the toothed plate 10 moves, it drives the gear 9 and the threaded cylinder 7 to rotate in a meshing manner, so that the bed 2 is constrained by the guide cylinder 21 and is controlled by the threaded column 8 to move vertically to lower the height. After loosening the push handle 12, the toothed plate 10 moves toward the side close to the stop block 16 under the push of the spring 18, and controls the threaded column 8 to rise in the threaded cylinder 7, so that the bed 2 can quickly rise with the patient. During the process, the moving distance of the toothed plate 10 is limited by the stop block 16, and the maximum rising height of the bed 2 is limited. After rotating the screw cylinder 14, the control screw 15 moves horizontally in the base 1, and the position of the stop block 16 is changed, so that the bed height can be adapted to the bed height required by the physician for the examination item.
