[0012] Technical effects and advantages of the present invention:
[0013] 1. The present invention is provided with a support assembly for adjusting the sitting and lying postures. The support assembly is divided into three parts, namely a base support, a back support and a leg support, so that it can better fit the human body structure. The angles of the back support and the leg support can be adjusted according to the specific conditions of the orthopedic patients. The sitting height and angle of the patient can be adjusted by the back support, and the patient's legs can be bent by the leg support. At the same time, the angle can be adjusted according to the specific conditions to avoid the patient's legs being unable to bend and move for a long time, resulting in leg discomfort. At the same time, the patient's sitting posture is made more comfortable. Since a soft cushion is provided on the top of the support assembly, the comfort of the patient during long-term bed rest is effectively increased.
[0014] 2. The present invention supports the hand position of orthopedic patients by providing a support assembly. When the patient is in a lying position, the guardrails in the support assembly are located on both sides of the bed frame to play a protective role. When the lying position is adjusted to a sitting position, as the angle of the support assembly changes, the guide rails slide on the top of the support frame, driving the top rods on both sides to move in the inner cavity of the fixed frame. As the top rods move, the fixed frame is pushed to rotate to one side through the limiting shaft, so that the guardrail rotates downward, and at the same time drives the armrest on one side to rotate to a horizontal state, replacing the position of the guardrail, which is located on both sides of the bed frame. When the patient is converted to a sitting position, the patient's hands can be placed on the top of the armrest to support the patient's hands, thereby avoiding the hands being squeezed and bent during the adjustment of the sitting or lying position.
[0015] 3. The present invention adjusts various parts of the bracket assembly by providing a first hydraulic cylinder and a second hydraulic cylinder. There is no need to manually adjust the angle of the equipment. When the angle needs to be adjusted, the first hydraulic cylinder pushes the back panel bracket to tilt upward, and at the same time the slide rail drives the base bracket to slide on the top of the support frame, so that the third rotating block rotates on the surface of the connecting rod, and the angle between the back panel bracket and the base bracket is adjusted as needed. As the guide rail moves, the second hydraulic cylinder pulls the leg bracket to rotate downward, and the leg bracket and the base bracket rotate through the first rotating block and the second rotating block to adjust the bending angle of the leg. During the movement of the guide rail, the top rod is driven to push the fixed frame to complete the conversion between the guardrail and the handrail, which is more convenient and quick to use.

[0027] Further, such as Figure 5 and Figure 6 As shown, one side of the bottom end of the leg support 44 is fixedly connected to a second connecting block 48, one side of the bottom end of the guide rail 3 is fixedly connected to a second mounting frame 12, one end of the second mounting frame 12 is fixedly connected to a second rotating connecting member 13, one end of the second rotating connecting member 13 is rotatably connected to a second hydraulic cylinder 14, and the protruding end of the second hydraulic cylinder 14 is rotatably connected to the second connecting block 48. The leg support 44 is pulled downward by the second hydraulic cylinder 14 to rotate. When the leg support 44 rotates downward, the first rotating block 42 and the second rotating block 45 will also rotate with each other. According to the specific situation of the patient, the rotation angle of the leg support 44 is adjusted so that the patient's legs can be bent, thereby avoiding the patient's legs being unable to bend and move for a long time, resulting in discomfort in the legs, and at the same time increasing the comfort of the patient's sitting posture.
[0028] Further, such as Figure 3 and Figure 5 As shown, three first rotating blocks 42 are fixedly connected to one end of the base bracket 41 close to the leg bracket 44, three second rotating blocks 45 are fixedly connected to one end of the leg bracket 44 close to the base bracket 41, and a third rotating block 46 is fixedly connected to one side of the bottom end of the back bracket 43.
[0029] Further, such as Figure 3 and Figure 5As shown, three first rotating blocks 42 and second rotating blocks 45 are arranged at equal distances, the positions of the first rotating blocks 42 and the second rotating blocks 45 correspond, the first rotating blocks 42 and the second rotating blocks 45 are rotatably connected, the leg support 44 and the base support 41 are rotated relative to each other through the first rotating blocks 42 and the second rotating blocks 45, one end of the inner wall of the guide rail 3 close to the back support 43 is fixedly connected with a connecting rod 8, the third rotating block 46 is rotatably connected to the middle part of the outer surface of the connecting rod 8, the back support 43 and the base support 41 are rotated relative to each other through the third rotating block 46 and the connecting rod 8, and the angles of the back support 43 and the leg support 44 are adjusted according to the specific conditions of the patient to adjust the patient's sitting or lying posture.
[0030] In this embodiment, if Figure 4 As shown, the support assembly 7 includes a limiting shaft 71 fixedly connected to both ends of the bed frame 1, the rotation angle of the limiting shaft 71 is between 0°-90°, the outer surface of the limiting shaft 71 is rotatably connected to a fixing frame 72, and the fixing frame 72 is rotated at both ends of the bed frame 1 through the limiting shaft 71, so that the rotation angle of the fixing frame 72 is between 0°-90°, and one end of the fixing frame 72 is fixedly connected to an armrest 74.
[0031] Further, such as Figure 4 and Figure 7 As shown, one end of the fixing frame 72 close to the handrail 74 is fixedly connected with a block 73, and the push rod 6 is located between the fixing frame 72 and the block 73. When the first hydraulic cylinder 11 pushes the back support 43 to rotate upward, the guide rail 3 will slide at the top of the support frame 2, driving the base support 41 to move toward the back support 43, so that the leg support 44 has enough rotation space. When the guide rail 3 moves, it will drive the push rods 6 on both sides to move. The end of the push rod 6 away from the guide rail 3 moves in the inner cavity of the fixing frame 72. As the push rod 6 moves, it pushes the fixing frame 72, and the fixing frame 72 rotates to one side through the limiting shaft 71. When the fixing frame 72 is in the initial state, the guardrail 75 is located at the top, and the handrail 74 is in a vertical state. After the fixing frame 72 is pushed, it can achieve 90° rotation through the limiting shaft 71, and the fixing frame After 72 rotates 90°, guide rail 3 stops moving, so that armrest 74 is rotated to a horizontal state, replacing the position of guardrail 75. When the patient is converted to a sitting position, the patient's hands can be placed on the top of armrest 74 to support the patient's hands, thereby avoiding the hands from being squeezed and bent during the adjustment of the sitting or lying position. When the sitting position is adjusted back to the lying position, guide rail 3 slides in the opposite direction, driving push rod 6 to move to the other side. When the fixed frame 72 is in the initial state, block 73 is located below push rod 6 and parallel to armrest 74. When the fixed frame 72 is rotated 90°, block 73 also rotates upward to be vertical and is located on the other side of push rod 6, so that when push rod 6 moves in the opposite direction, it can push block 73, driving the fixed frame 72 to rotate 90° in the opposite direction, so that the armrest 74 and guardrail 75 return to their initial positions.
[0032] Further, such as Figure 1 , Figure 4 and Figure 5 As shown, the other end of the fixing frame 72 is fixedly connected with a guardrail 75, and the end of the guardrail 75 away from the fixing frame 72 is fixedly connected to the armrest 74, and the position of the guardrail 75 is perpendicular to the position of the armrest 74. The two armrests 74 and the guardrail 75 are respectively located on both sides of the cushion 5, and the end of the armrest 74 away from the fixing frame 72 is provided with an arc-shaped groove, which increases the comfort of the patient's hands. When the patient is in a lying position, the fixing frame 72 is in an initial state, and the guardrail 75 is located on both sides of the cushion 5 to protect the patient. When the patient is adjusted to a sitting position, the fixing frame 72 rotates so that the armrest 74 replaces the guardrail 75 to support the patient's hands, making the device more convenient and quick to use.
[0033] The working principle of the present invention is as follows: first, the orthopedic patient lies on the cushion 5. When the patient needs to adjust his sitting posture, the first hydraulic cylinder 11 and the second hydraulic cylinder 14 are started, and the back support 43 is pushed to tilt upward through the extended end of the first hydraulic cylinder 11. At the same time, the back support 43 rotates on the surface of the connecting rod 8 through the third rotating block 46. When the back support 43 rotates, the guide rail 3 is started at the same time, sliding on the top of the support frame 2, driving the base support 41 to move toward the back support 43, so that the leg support 44 has enough rotation space. As the back support 43 continues to rotate and tilt upward, the first connecting block 47 will be connected with the first hydraulic cylinder 11. The extended ends of the cylinders 11 rotate with each other, and the first hydraulic cylinder 11 also rotates with the first rotating connector 10. The height and angle of the patient's sitting up are adjusted by the rotation of the back support 43. Then, the extended end of the second hydraulic cylinder 14 pulls the leg support 44 to rotate downward. When the leg support 44 rotates downward, the first rotating block 42 and the second rotating block 45 also rotate with each other. According to the specific situation of the patient, the rotation angle of the leg support 44 is adjusted so that the patient's legs can be bent, so as to avoid the patient's legs being unable to bend and move for a long time, resulting in discomfort in the legs, and at the same time increase the comfort of the patient's sitting posture;
[0034] When the guide rail 3 moves, it will drive the push rods 6 on both sides to move. The end of the push rod 6 away from the guide rail 3 moves in the inner cavity of the fixing frame 72. As the push rod 6 moves, it pushes the fixing frame 72, and the fixing frame 72 rotates to one side through the limit shaft 71. When the fixing frame 72 is in the initial state, the guardrail 75 is located at the top, and the armrest 74 is in a vertical state. After the fixing frame 72 is pushed, it realizes a 90° rotation through the limit shaft 71. After the fixing frame 72 rotates 90°, the guide rail 3 stops moving, so that the armrest 74 is rotated to a horizontal state, and the block 73 is rotated to a vertical state with the rotation of the fixing frame 72. When the patient is converted to a sitting position, the patient's hand can be placed on the top of the armrest 74 to support the patient's hand, so as to avoid the hand being squeezed and bent during the adjustment of the sitting or lying position;
[0035] When the patient is adjusted from a sitting position to a lying position, the guide rail 3 slides in the opposite direction, and the extended ends of the first hydraulic cylinder 11 and the second hydraulic cylinder 14 also begin to contract, driving the push rod 6 to move to the other side. The block 73 is in a vertical state at this time and is located on the other side of the push rod 6, so that the push rod 6 can push the block 73 when it moves in the opposite direction, driving the fixing frame 72 to rotate 90° in the opposite direction and return to the initial position. At the same time, the armrest 74 and the guardrail 75 also return to the initial position, so that the guardrail 75 is reset to the two sides of the cushion 5, which plays a protective role for the patient.
