[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the positionable and adjustable cardiology rehabilitation exercise and nursing bed adopts a new structural design, and its specific contents are as follows: (1) When using the positioning and adjustable cardiology rehabilitation exercise nursing bed, the device can be placed in the rehabilitation room first. When the angle of the movable bed board needs to be adjusted during use, the motor can be started to drive the vertical rod to rotate. At this time, the push plate rises in the vertical direction under the limiting action of the vertical rod and the main bed board, and then the push plate pushes the movable bed board. At this time, the movable bed board and the connecting block will rotate around the inner rod on the main bed board. After adjusting to the required position, the motor can be stopped. Thus, the device has the function of positioning and adjustment. When the movable bed board rotates, the fixed block makes the connection block and the inner rod rotate more stably. Furthermore, when the movable bed plate rotates, the rotating shaft is driven to rotate by the traction rope, and when the rotating shaft rotates, the pipe sleeve and the protrusion will be driven to rotate synchronously. At this time, the protrusion will intermittently massage the patient's back, playing a massage role and optimizing comfort; Furthermore, when the shaft rotates, the torsion spring will be stretched, and when the motor drives the vertical rod to rotate, the push plate descends, and the movable bed plate rotates, the shaft loses the pulling force of the traction rope. At this time, the shaft rotates under the action of the torsion spring. When the shaft rotates, the traction rope will be reeled in, which is convenient for the next use of the shaft. (2) When the patient needs to exercise his / her arms, the patient can first take the handle out of the outer box, and then push and pull the handle to drive the outer box to move. When the outer box is pushed, the limit rod slides inside the main bed board, and the connecting spring is squeezed. When the handle is pulled, the connecting spring and the limit rod move the outer box and the handle back, which plays an auxiliary role. The above process is repeated, and the patient can exercise his / her arms. Furthermore, when the outer box is pushed, the outer box drives the long strip and the tooth block to move synchronously. At this time, the column rotates inside the main bed board under the action of the tooth block and the gear. When the column rotates, it drives the push block to rotate synchronously. When the push block rotates to contact the lower connecting block, the push block drives the pressure plate to rotate around the connecting shaft through the lower connecting block. When the push block rotates to no longer contact the lower connecting block, the pressure plate and the connecting shaft rotate under the action of their own gravity. Repeating the above process, the pressure plate can intermittently lift the patient's legs, which plays a role in exercising the legs, and the support rod limits the maximum rotation angle of the pressure plate to ensure stability. Furthermore, when the outer box moves back, the column will rotate again under the action of the tooth block and the gear, and the leg exercise action will occur again, that is, the patient can exercise his arms and legs well, which is convenient for the rehabilitation of cardiology patients.

[0020] The vertical rod 9 is threadedly connected to the push plate 10 , and the surface of the main bed board 1 is a through structure, and the surface of the push plate 10 is in contact with the inner wall of the main bed board 1 , and the upper surface of the push plate 10 is in contact with the lower surface of the movable bed board 2 .

[0021] When in use, the device can be placed in the rehabilitation room and the ward first. During use, when the angle of the movable bed board 2 needs to be adjusted, the motor 8 can be started to drive the vertical rod 9 to rotate. At this time, the push plate 10 rises in the vertical direction under the limiting action of the vertical rod 9 and the main bed board 1, and then the push plate 10 pushes the movable bed board 2. At this time, the movable bed board 2 and the connecting block 5 will rotate on the main bed board 1 around the inner rod 15 and the fixed block 6. After adjusting to the required position, the motor 8 can be stopped, thereby having the function of positioning adjustment. When the movable bed board 2 rotates, the fixed block 6 makes the connection block 5 and the inner rod 15 rotate more stably.

[0022] Embodiment 2: Different from Embodiment 1, the convex block 14 is provided to enable the movable bed plate 2 to rotate while massaging the patient's back, thereby improving comfort. Figure 4 and Figure 5 As shown: A traction rope 11 is wrapped and fixedly connected to the surface of the rotating shaft 12, and the other side of the traction rope 11 is fixedly connected to the upper surface of the main bed board 1, and the rotating shaft 12 is evenly spaced on the surface of the main bed board 1, and the protrusions 14 are evenly distributed on the surface of the pipe sleeve 13. A torsion spring 16 that plays an elastic reset role is fixedly connected to the surface of the rotating shaft 12, and the other side of the torsion spring 16 is fixedly connected to the inner wall of the movable bed board 2.

[0023] When the movable bed board 2 rotates, the rotating shaft 12 is driven to rotate by the traction rope 11. When the rotating shaft 12 rotates, it will drive the sleeve 13 and the protrusion 14 to rotate synchronously. At this time, the protrusion 14 will intermittently massage the patient's back, which plays a massage role and optimizes comfort. When the rotating shaft 12 rotates, the torsion spring 16 will be stretched, and then the motor 8 drives the vertical rod 9 to rotate, the push plate 10 descends, and the movable bed board 2 rotates. The rotating shaft 12 will lose the tension of the traction rope 11. At this time, the rotating shaft 12 rotates under the action of the torsion spring 16 (when the rotating shaft 12 rotates, it will drive the sleeve 13 and the protrusion 14 to rotate again, and then the protrusion 14 will massage the patient's back again, further optimizing comfort). When the rotating shaft 12 rotates, the traction rope 11 will be reeled in to facilitate the next use of the rotating shaft 12.

[0024] Embodiment 3: Different from Embodiment 2, the patient can exercise his legs while exercising his arms, which is convenient for the patient's recovery. Figure 6-Figure 11 As shown: A limiting rod 19 is fixedly connected to the surface of the outer box 17, and the limiting rod 19 is slidably arranged inside the main bed board 1, and the outer box 17 is symmetrically distributed about the center of the main bed board 1, and a connecting spring 20 that plays an elastic reset role is fixedly connected to the surface of the limiting rod 19, and the other side of the connecting spring 20 is fixedly connected to the inner wall of the main bed board 1.

[0025] The strip 21 is an inverted "L" structure, and tooth blocks 22 are fixedly arranged at equal intervals on the surface of the strip 21, a gear 28 meshing with the tooth block 22 is fixedly connected to the surface of the column 25, a push block 27 is fixedly connected to the surface of the column 25, and a lower connecting block 26 corresponding to the push block 27 is fixedly connected to the lower surface of the pressure plate 24, and the surface of the lower connecting block 26 is inclined.

[0026] The surface of the column 25 is fixedly connected to a limit plate 29, and the limit plate 29 is a cylindrical structure. The lower surface of the main bed board 1 is fixedly connected to a support rod 30, and the upper surface of the support rod 30 is initially in contact with the lower surface of the pressure plate 24, and the pressure plate 24 is symmetrically distributed about the center of the main bed board 1.

[0027] When the patient needs to exercise his arm, he can first take the handle 18 out of the outer box 17, and then push and pull the handle 18 to drive the outer box 17 to move. When the outer box 17 is pushed, the limit rod 19 slides inside the main bed board 1. At this time, the connecting spring 20 is squeezed, and when the handle 18 is pulled, the connecting spring 20 and the limit rod 19 make the outer box 17 and the handle 18 move back, which plays an auxiliary role. By repeating the above process, the patient can exercise the muscles and joints of the arm through the outer box 17 and the handle 18. When the outer box 17 is pushed, the outer box 17 drives the long strip 21 and the tooth block 22 to move synchronously. At this time, the column 25 rotates inside the main bed board 1 under the action of the tooth block 22 and the gear 28 (the limit plate 29 makes the rotation of the column 25 more stable, so that the column 25 will not move in the vertical direction). When the column 25 rotates, it drives the push block 27 to rotate synchronously. When the push block 27 rotates to contact with the lower connecting block 26, the push block 27 drives the pressure plate 24 to rotate around the connecting shaft 23 through the lower connecting block 26. When the push block 27 rotates to no longer contact with the lower connecting block 26, the pressure plate 24 and the connecting shaft 23 rotate under the action of their own gravity. The above process is repeated, and the pressure plate 24 can intermittently lift the patient's legs to exercise the legs. The support rod 30 limits the maximum rotation angle of the pressure plate 24 to ensure stability. When the outer box 17 moves back, the column 25 will rotate again under the action of the tooth block 22 and the gear 28, and the action of exercising the leg muscles and joints will occur again, that is, the patient can exercise the muscles and joints of the arms and legs well, which is convenient for the rehabilitation of cardiology patients.

[0028] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
