[0031] like Figures 1 to 4 As shown, the utility model provides a joint rehabilitation device.

[0032] Specifically, by Figure 1-Figure 4 Given, including:

[0033] Support leg 1;

[0034] A support plate 2 mounted on the top surface of the support leg 1;

[0035] A backrest 3 mounted behind the support plate 2;

[0036] An adjustment assembly for adjusting the flexion and extension position;

[0037] The adjustment assembly includes a seat plate 4 installed on the top surface of the support plate 2, a rotatable first screw 14 installed on one side of the seat plate 4, a slidable mounting plate 5 installed on the top surface of the support plate 2, and a second docking column 20 fixedly installed on one side of the mounting plate 5. The first screw 14 is threadedly connected to the second docking column 20.

[0038] In the utility model, when in use, first let the patient sit on the seat plate 4, and then straighten the legs. At this time, the user needs to observe the position of the connection between the first folding plate 7 and the second folding plate 8. If it is not directly below the patient's knee, turn the knob 15. During the rotation of the knob 15, the first screw 14 will be driven to rotate. After the first screw 14 is rotated, the second docking column 20 will be driven away from or close to the seat plate 4, and the second docking column 20 is fixedly connected to one side of the mounting plate 5, and the first folding plate 7 and the second folding plate 8 are simultaneously above the mounting plate 5. Therefore, after turning the knob 15, the first folding plate 7 and the second folding plate 8 will move closer to or away from the seat plate 4 together with the mounting plate 5. The user needs to observe during the process until the connection between the first folding plate 7 and the second folding plate 8 is directly below the patient's knee, and then stop adjusting.

[0039] Furthermore, as a specific implementation of the present invention, the present invention provides a joint rehabilitation device.

[0040] Specifically, Figure 1-Figure 3 As shown, it also includes a flexion and extension component, which includes a docking plate 6 fixedly mounted on the top surface of the mounting plate 5, a first folding plate 7 rotatably connected to the front end of the docking plate 6, a second folding plate 8 rotatably connected to the front end of the first folding plate 7, a driving motor 11 installed on the top surface of the mounting plate 5, a rotatable reciprocating screw 10 connected to one end of the driving motor 11, a docking sleeve 9 threadedly connected on the outer wall of the reciprocating screw 10, and an outer wall of the docking sleeve 9 rotatably connected to the bottom end of the second folding plate 8.

[0041] In the utility model, the driving motor 11 is started first, and the driving motor 11 will drive the reciprocating screw 10 to rotate after it is started, and the docking sleeve 9 is threadedly connected to the outer wall of the reciprocating screw 10, so the reciprocating screw 10 will drive the docking sleeve 9 to move after it rotates. Because the unique thread on the surface of the reciprocating screw 10 will drive the docking sleeve 9 to reciprocate within the range of the reciprocating screw 10, and because the bottom end of the second folding plate 8 is rotatably connected to the outer wall of the docking sleeve 9, the docking sleeve 9 will resist the second folding plate 8 during the movement, thereby changing the angle of the second folding plate 8 itself, and the other end of the second folding plate 8 The first folding plate 7 is rotatably connected, so after the angle of the second folding plate 8 is changed, the first folding plate 7 will move together with the second folding plate 8, thereby lifting the connection between the first folding plate 7 and the second folding plate 8, and the docking sleeve 9 that reciprocates on the outer wall of the reciprocating screw 10 will continuously lift and lower the connection between the first folding plate 7 and the second folding plate 8. During the process, the patient's knee position is above the connection between the first folding plate 7 and the second folding plate 8, so in the process of lifting and lowering the connection between the first folding plate 7 and the second folding plate 8, the patient's knee also completes the leg flexion and extension action, which can help the patient rehabilitate the knee.

[0042] Furthermore, as another specific implementation of the present invention, the present invention provides a joint rehabilitation device.

[0043] Specifically, Figure 1-Figure 3 As shown, a second guide rod 13 is fixedly installed on the other side of the seat plate 4, and a sleeve adapted to the second guide rod 13 is fixedly installed on the other side of the mounting plate 5. The second guide rod 13 is slidable in the sleeve, and a knob 15 is connected to the top end of the first screw rod 14.

[0044] In the present invention, in order to make the movement of the mounting plate 5 more stable, a second guide rod 13 and a sleeve are provided so that the mounting plate 5 is limited by the second guide rod 13 in the process of moving away from or approaching the seat plate 4, and will not shake easily. It should be noted that a slide groove 21 is provided on the top surface of the support plate 2, and a slider is fixedly connected to the bottom of the mounting plate 5, and the slider slides in the slide groove 21. The cooperation of the slider and the slide groove 21 also makes the movement of the mounting plate 5 more stable.

[0045] Furthermore, as another specific implementation of the present invention, the present invention provides a joint rehabilitation device.

[0046] Specifically, Figure 1-Figure 3 As shown, a first guide rod 12 is fixedly installed on the top surface of the mounting plate 5 at a position symmetrical to the reciprocating screw 10, and a ring is slidably sleeved on the outer wall of the first guide rod 12. While the ring is on the outer wall of the first guide rod 12, the support leg 1 can also be rotatably connected to the bottom end of the second folding plate 8.

[0047] In the present invention, in order to limit the second folding plate 8 by the first guide rod 12 during the movement, the movement of the second folding plate 8 is made more stable, thereby reducing the pain of the patient.

[0048] Furthermore, as another specific implementation of the present invention, the present invention provides a joint rehabilitation device.

[0049] Specifically, Figure 4 As shown, a rotatable second screw 16 is installed at the bottom of the support plate 2, and a first docking column 17 is threadedly connected to the outer wall of the second screw 16. The front end of the first docking column 17 is rotatably connected to a connecting rod 19, and the other end of the connecting rod 19 is rotatably connected to the bottom of the backrest 3.

[0050] In the present invention, in order to allow patients to have a better experience when using the device, the first docking column 17 can be moved away from or close to the second screw 16 body by rotating the second screw 16, and the first docking column 17 will contact the connecting rod 19 during the movement, thereby driving the backrest 3 to rotate, so that the angle of the backrest 3 can be adjusted, so that the user can lie on the device more comfortably.

[0051] Furthermore, as another specific implementation of the present invention, the present invention provides a joint rehabilitation device.

[0052] Specifically, Figure 4 As shown, a retaining block 18 is fixedly installed on the bottom surface of the support plate 2, and a through hole compatible with the first docking column 17 is opened inside the retaining block 18. The first docking column 17 can be slidably located in the through hole opened in the retaining block 18, and a rotating handle is installed at the front end of the second screw rod 16.

[0053] In the present invention, in order to make the movement of the first docking column 17 more stable, a retaining block 18 is provided so that the first docking column 17 is effectively supported during the movement, so that the first docking column 17 is not easily damaged, thereby increasing the service life of the device.

[0054] Working principle: When in use, first let the patient sit on the seat plate 4, and then straighten the legs. At this time, the user needs to observe the position of the connection between the first folding plate 7 and the second folding plate 8. If it is not directly below the patient's knee, turn the knob 15. During the rotation of the knob 15, the first screw 14 will be driven to rotate. After the first screw 14 is rotated, the second docking column 20 will be driven away from or close to the seat plate 4, and the second docking column 20 is fixedly connected to one side of the mounting plate 5, and the first folding plate 7 and the second folding plate 8 are both above the mounting plate 5. Therefore, after turning the knob 15, the first folding plate 7 and the second folding plate 8 will move closer to or away from the seat plate 4 together with the mounting plate 5. The user needs to observe during the process until the connection between the first folding plate 7 and the second folding plate 8 is directly below the patient's knee before stopping the adjustment.

[0055] After the adjustment is completed, the driving motor 11 can be started. After the driving motor 11 is started, the reciprocating screw 10 will be driven to rotate, and the docking sleeve 9 is threadedly connected to the outer wall of the reciprocating screw 10, so the reciprocating screw 10 will drive the docking sleeve 9 to move after it rotates. Because the unique thread on the surface of the reciprocating screw 10 will drive the docking sleeve 9 to reciprocate within the range of the reciprocating screw 10, and because the bottom end of the second folding plate 8 is rotatably connected to the outer wall of the docking sleeve 9, the docking sleeve 9 will resist the second folding plate 8 during the movement, thereby changing the angle of the second folding plate 8 itself, and the other end of the second folding plate 8 can be The first folding plate 7 is connected by rotation, so after the angle of the second folding plate 8 is changed, the first folding plate 7 will move together with the second folding plate 8, thereby lifting the connection between the first folding plate 7 and the second folding plate 8, and the docking sleeve 9 that moves back and forth on the outer wall of the reciprocating screw 10 will continuously lift and lower the connection between the first folding plate 7 and the second folding plate 8. During the process, the patient's knee position is above the connection between the first folding plate 7 and the second folding plate 8, so in the process of lifting and lowering the connection between the first folding plate 7 and the second folding plate 8, the patient's knee also completes the leg flexion and extension action, which can help the patient rehabilitate the knee.

[0056] By setting up the adjustment component, the device can adapt to the knee positions of different patients. Each person's physical condition is different, and the knee position is also different. The adjustment component can accurately position the protrusion of the flexion and extension component at the patient's knee position, so as to carry out targeted rehabilitation training and accelerate the recovery of the knee.

[0057] By setting up the flexion and extension component, after completing the adjustment of the device, the device only needs to start the drive motor 11 to make the patient's legs flex and extend continuously, which can avoid adhesion of soft tissue around the knee joint and prevent muscle atrophy around the knee. At the same time, it reduces manpower consumption and speeds up the patient's recovery.

[0058] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
