The output end of the electric telescopic rod 13 is rotatably connected with a connecting frame 14, the connecting frame 14 plays a role of transition connection and force transmission between the electric telescopic rod 13 and the rotating shaft 2. The rotatable connection of the connecting frame 14 makes the linear motion output by the electric telescopic rod 13 be smoothly converted into the rotary motion of the connecting frame 14, thereby driving the rotating shaft 2 to rotate, one end of the connecting frame 14 away from the electric telescopic rod 13 is fixedly connected to the outer wall of one of the rotating shafts 2, so that the power of the electric telescopic rod 13 can be accurately and accurately transmitted to the rotating shaft 2, and the rotating shaft 2 can rotate in the expected direction and speed, the two rotating frames 10 are fixedly connected to the outer wall of the rotating shaft 2, and the rotating frame 10 is part of the transmission structure, and the fixed connection with the rotating shaft 2 enables it to rotate with the rotating shaft 2. The second connecting rod 11 is rotatably connected between the two rotating frames 10, through the rotatable connection of the second connecting rod 11, the motion of the two rotating frames 10 can be associated with each other, so that the motion of the whole transmission system is more coordinated and consistent, and the situation of local uneven stress or motion interference is avoided.

[0030] With reference to Figure 2 , the jacking assembly includes a plurality of rotating plates 3, the rotating plates 3 are fixedly connected to the outer wall of the rotating shaft 2, and under the rotating action of the rotating shaft 2, the rotating plates 3 can rotate around the rotating shaft 2, thereby driving the connected connecting plates 4 to move correspondingly, realizing the function of converting the rotary motion of the rotating shaft 2 into vertical lifting motion. The connecting plates 4 are rotatably connected to the side away from the rotating shaft 2 of the rotating plates 3, and the rotatable connection between the rotating plates 3 and the connecting plates 4 forms an movable joint structure, so that the connecting plates 4 can move relatively under the driving of the rotating plates 3, the mounting plates 5 are rotatably connected to the top of the connecting plates 4, during the lifting process of the nursing bed surface, the mounting plates 5 can rotate and displace correspondingly with the movement of the connecting plates 4, thereby realizing the stable support and vertical lifting of the bed frame 6, the bed frame 6 is fixedly connected between the tops of the two mounting plates 5, and the fixed connection between the mounting plates 5 and the bed frame 6 ensures that the bed frame 6 can be stably installed on the jacking assembly and vertically move with the lifting of the jacking assembly.

[0031] With reference to Figures 1-3The limiting assembly includes four fixed plates 8 fixedly connected to the inner wall of the chassis 1, which are evenly distributed on the inner wall of the chassis 1 to form a stable frame structure and provide a reliable basis for the installation of the first connecting rod 9. The opposite side edges of adjacent two fixed plates 8 are both rotationally connected with the first connecting rod 9. The rotational connection between the first connecting rod 9 and the fixed plate 8 allows the first connecting rod 9 to rotate flexibly within a certain range, and cooperates with other components in the jacking assembly to effectively limit the movement of the jacking assembly.

[0032] With reference to Figure 1 and Figure 3 , a plurality of bed plates 7 are installed inside the bed frame 6, which are combined together to form the bed surface of the nursing bed and can provide a comfortable lying surface for the user.

[0033] With reference to Figure 2 , the first connecting rod 9 is rotationally connected to the middle part of the connecting plate 4 on the side away from the fixed plate 8. The rotational connection allows the first connecting rod 9 to accurately limit and guide the movement of the connecting plate 4 during the lifting of the nursing bed. When the jacking assembly drives the connecting plate 4 to move vertically, the first connecting rod 9 forms a stable triangular structure through the rotational connection with the fixed plate 8 and the connecting plate 4, which limits the horizontal displacement of the connecting plate 4 and ensures that it can only move vertically, thereby ensuring the stability and accuracy of the lifting of the bed surface of the nursing bed.

[0034] With reference to Figures 1-3 , universal wheels 15 are fixedly connected to the four corners of the bottom of the chassis 1. The universal wheels 15 make the nursing bed have good mobility and flexibility, which facilitates the movement and use of the nursing bed in different places.

[0035] With reference to Figures 1-3 , the plurality of rotational connections are all damping shafts. During the lifting of the bed surface, the damping shafts can provide certain resistance to make the movement of the rotating components more stable and slow, avoiding the impact force caused by rapid rotation to cause discomfort to the user or damage to the components of the nursing bed.

[0036] Working principle: When the electric telescopic rod 13 receives a control signal to start working, its output end performs telescopic movement. Since the output end of the electric telescopic rod 13 is rotationally connected with the connecting frame 14, which is fixedly connected to the outer wall of one of the rotating shafts 2, the telescopic movement of the electric telescopic rod 13 will drive one of the rotating shafts 2 to rotate. The rotation of the rotating shaft 2 drives the rotating frame 10 to rotate, and through the second connecting rod 11, the other rotating frame 10 is driven to rotate, further driving the other rotating shaft 2 to rotate synchronously.

[0037] With the rotation of the rotating shaft 2, the rotating plate 3 fixed on the outer wall thereof rotates synchronously. The side of the rotating plate 3 away from the rotating shaft 2 is rotationally connected with the connecting plate 4, so that the rotation of the rotating plate 3 will cause the connecting plate 4 to move correspondingly. The top of the connecting plate 4 is rotationally connected with the mounting plate 5, and the top of the two mounting plates 5 is fixedly connected with the bed frame 6. In this linkage process, the bed frame 6 will realize the lifting in the vertical direction.

[0038] In the lifting process of the bed frame 6, the limiting assembly plays a key role in limiting and stabilizing. The four fixed plates 8 are fixed on the inner wall of the bottom frame 1, and the first connecting rod 9 is rotationally connected to the side edge of the adjacent two fixed plates 8. The side of the first connecting rod 9 away from the fixed plate 8 is rotationally connected to the middle of the connecting plate 4. Through the specific structure formed by the first connecting rod 9, the fixed plate 8 and the connecting plate 4, the displacement of the connecting plate 4 in the horizontal direction is limited, so that the bed frame 6 can only stably lift along the vertical direction, avoiding unstable conditions such as deviation or shaking.

[0039] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
