[0032] The telescopic adjustment component 3 includes a telescopic rod 302. One end of the telescopic rod 302 is connected to a telescopic motor 301 and is controlled by the telescopic motor 301 for telescoping;

[0033] The rotating frame 4 includes a rotating rod 401. The other end of the telescopic rod 302 is rotatably connected to the rotating rod 401 through a lever connecting part 404;

[0034] The telescopic motor 301 controls the telescopic rod 302 to telescope towards one end of the rotating rod 401. By rotating at the lever connecting part 404 and pushing the lever connecting part 404 and the rotating rod 401 to perform a reciprocating rotational movement towards the other side of the lever connecting part 404, and driving the entire rotating frame 4 to perform a reciprocating rotational movement towards the other side of the lever connecting part 404 through the rotating member 403, so as to achieve the angle adjustment between the fixing frame 2 and the rotating frame 4.

[0035] Specifically, reset elastic members 5 are connected between the two ends of the rotating rod 401 and the fixed frame 2. The reset elastic members 5 and the lever connection part 404 are both arranged on the upper surface of the rotating rod 401. The reset elastic members 5 are arranged in parallel on both sides of the telescopic adjustment assembly 3. The elastic members 5 buffer the telescopic movement of the telescopic rod 302 and drive the rotating rod 401 to reset through the rebound of the elastic members 5, so that the rotating rod 401 is more evenly stressed and more stable to use during the rotation process.

[0036] Furthermore, the lever connection part 404 is arranged on the rotating rod 401 and is on a different horizontal plane from the telescopic rod 302. The telescopic rod 302 is inclined outward to be connected with the lever connection part 404, so as to achieve the reciprocating centrifugal rotation movement of the lever connection part 404 and the rotating rod 401 to the other side of the lever connection part 404 by the rotation of the telescopic rod 302 at the lever connection part 404.

[0037] Preferably, both ends of the reset elastic member 5 are connected to the rotating rod 401 and the fixed frame 2 through the second connecting ears 9. The second connecting ears 9 are arranged on the same side of the rotating rod 401 and the fixed frame 2 and are on the same side as the lever connection part 404.

[0038] Furthermore, the lever connection part 404 includes connecting ears 406 symmetrically arranged on both sides of the end of the telescopic rod 302. The end of the telescopic rod 302 is connected through the rotating shaft 407 passing through the connecting ears 406 on both sides and the telescopic rod 302;

[0039] Extend the telescopic rod 302. The telescopic rod 302 drives the rotating shaft 407 to rotate at the connection of the connecting ears 406, and the rotating rod 401 makes a reciprocating centrifugal rotation outward with the rotating shaft 407 as the center.

[0040] Preferably, support rods 402 are fixedly and vertically connected to both ends of the rotating rod 401. The outer sides of the upper ends of the support rods 402 are rotatably connected to the fixed frame 2 through rotating parts 403, and installation parts 405 are arranged at the lower ends of the support rods 402 to facilitate the connection between the support rods 402 and the backrest 8.

[0041] As Figure 1 and Figure 2 shown, the rotating rod 401 is preferably set as a square rod-shaped structure. The lever connection part 404 and the second connecting ears 9 are arranged on the upper side of the square-structured rotating rod 401. The telescopic rod 302 is arranged inside the rotating rod 401 and is inclined upward to be connected with the lever connection part 404 on the upper side of the rotating rod 401. The square-structured rotating rod 401 facilitates the installation of the support rods 402 at both ends of the rotating rod 401 and the connection of the lever connection part 404 and the second connecting ears 9.

[0042] As Figure 6As shown in the figure, this is the general state diagram of the adjusting device 1 in the present utility model. In the normal state, the fixed frame 2 of the adjusting device 1 rotates upward, the rotating frame 4 rotates downward and is vertically installed in the bed backrest 6. The fixed frame 2 is fixedly installed at the headrest part 7. The lower end of the rotating frame 4 is fixedly connected to the backrest part 8. During the installation process, one side of the lever connection part 404 of the telescopic rod 302 is installed inside the bed backrest 6. At this time, the included angle between the fixed frame 2 and the rotating frame 4 is close to 180 degrees. At this time, the whole adjusting device 1 is in a straight line, and the telescopic rod 302 is in the shortest state.

[0043] As Figure 5 shown, when it is necessary to adjust the backrest part 8, the telescopic motor 301 is connected through a wire. The telescopic rod 302 is controlled by the telescopic motor 301 to extend. At this time, the telescopic rod 302 rotates at the lever connection part 404 and pushes the lever connection part 404 and the rotating rod 401 to rotate centrifugally to the other side of the lever connection part 404, that is, the bed tail side, thereby driving the two side support rods 402 to rotate to the bed tail side with the rotating part 403 as the center, adjusting the angle between the fixed frame 2 and the rotating frame 4. Then, it is connected to the backrest part 8 through the installation part 405. At this time, the backrest part 8 also rotates synchronously with the rotating frame 4. The backrest part 8 rotates upward toward the bed tail side, thus forming an inclined plane for people to lean back. By controlling the length of the telescopic rod 302 through the telescopic motor 301, the inclination angle of the backrest part 8 can be adjusted according to different needs of people. The operation and use are fast, flexible and free.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
