[0033] When working, the motor 11 is started. Since the front end of the transmission shaft 13 is fixedly connected to the rear end of the primary screw rod 16 through the connecting component 7, the rear end of the transmission shaft 13 is fixedly connected to the output shaft of the motor 11 through the connecting component 7, thereby driving the primary screw rod 16 to rotate. The primary screw rod 16 provides driving force for the knee flexion mechanism 2, thereby driving the knee flexion mechanism 2 to arch upward, and then driving the patient's knee joint to bend upward, so that the patient's knee joint can be flexed and extended.

[0034] As an embodiment of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the knee flexion mechanism 2 includes a front frame plate 21, a rear frame plate 22, a primary hinge rod 23, a primary hinge shaft 24, a secondary hinge rod 25, a secondary hinge seat 26, a bracket 27 and a threaded sleeve 28. The front frame plate 21 is arranged above the front side of the primary screw rod 16, and the rear frame plate 22 is arranged above the rear side of the primary screw rod 16. The bracket 27 is fixedly connected to the upper end surfaces of the front frame plate 21 and the rear frame plate 22, respectively, and the bracket 27 is a semi-cylindrical structure. The primary hinge rod 23 is arranged between the front frame plate 21 and the rear frame plate 22 in a V-shaped structure. The lower ends of the two primary hinge rods 23 are hinged through the primary hinge shaft 24, and the upper end of the front primary hinge rod 23 is connected to the lower end of the front frame plate 21. The rear center position of the face is fixedly connected, and the upper end of the rear primary hinged rod 23 is fixedly connected to the front center position of the lower end face of the rear frame plate 22. Three secondary hinged seats 26 are fixedly connected at equal distances on the upper end face of the front fixed plate 12, and three secondary hinged rods 25 are correspondingly fixedly connected to the front side of the lower end face of the front frame plate 21, and the lower ends of the secondary hinged rods 25 are respectively hinged to the secondary hinged seats 26. The rear center position of the lower end face of the rear frame plate 22 is also symmetrically fixedly connected with a combination structure of the secondary hinged rod 25 and the secondary hinged seat 26. The lower end of the secondary hinged seat 26 in the middle position of the rear side is fixedly connected with a threaded sleeve 28 of a semicircular ring structure, and the threaded sleeve 28 is threadedly connected to the primary screw rod 16.

[0035] During operation, the patient's upper body is padded to the same height as the front frame plate 21, and then the patient's thigh and calf are placed in the brackets 27 on the front frame plate 21 and the rear frame plate 22 respectively. The bracket 27 with a semi-cylindrical structure can prevent the patient's thigh and calf from sliding off the bracket 27 during flexion and extension. Since the threaded sleeve 28 is threadedly connected to the primary screw rod 16, when the primary screw rod 16 rotates, the threaded sleeve 28 will move forward along the primary screw rod 16. In addition, because the front frame plate 21 is hinged to the secondary hinge seat 26 on the front side fixing plate 12 through the secondary hinge rod 25, the primary hinge rod 23 under the front frame plate 21 and the rear frame plate 22 is hinged through the primary hinge shaft 24, and the rear frame The secondary hinge rod 25 at the rear center position of the lower end surface of the plate 22 is hinged to the secondary hinge seat 26 on the threaded sleeve 28, so that the threaded sleeve 28 will arch the front end of the rear frame plate 22 upward during the forward movement, and the rear frame plate 22 drives the rear end of the front frame plate 21 to arch upward, thereby driving the patient's knee joint to arch upward, and then the output shaft of the control motor 11 is reversed to drive the threaded sleeve 28 to move backward, thereby driving the front frame plate 21 and the rear frame plate 22 to fall back, and then driving the patient's knee joint to fall back, so that the patient's knee joint can be flexed and extended. The arching amplitude of the front frame plate 21 and the rear frame plate 22 can be adjusted according to the patient's condition, thereby improving the rehabilitation treatment effect on the patient.

[0036] As an embodiment of the present invention, Figure 4 As shown, the threaded sleeve 28 is symmetrically provided with a combination structure of a secondary hinged rod 25 and a secondary hinged seat 26 on the left and right sides. The lower ends of the secondary hinged seats 26 are fixedly connected with primary collars 19, and the primary collars 19 are slidably sleeved on the primary guide rod 18.

[0037] During operation, the front end of the rear frame plate 22 will drive the primary ring 19 to slide back and forth on the primary guide rod 18 during the process of arching upward and then falling back downward. The cooperation between the primary ring 19 and the primary guide rod 18 can guide the rear frame plate 22 and improve the stability, thereby preventing the rear frame plate 22 from shaking during movement.

[0041] During operation, the front end of the rubber sleeve 8 is fixedly sleeved on the rear end of the front frame plate 21, and the rear end of the rubber sleeve 8 is fixedly sleeved on the front end of the rear frame plate 22, so that when the front frame plate 21 and the rear frame plate 22 are arched upward, the patient's knee joint can be protected by the rubber sleeve 8. Since the upper limit plate 81 is mounted on the upper end surface of the lower limit plate 82, the rear end of the rear frame plate 22 cannot be lifted upward, and the rear end of the front frame plate 21 cannot be bent downward, so that the rear frame plate 22 and the front frame plate 21 can be kept in a straight line, ensuring that the subsequent lifting movement can be carried out normally.

[0042] As an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the connecting component 7 includes a connecting sleeve 71, a clamping block 72 and a clamping groove 73.

Since the threaded sleeve 28 is threadedly connected to the primary screw rod 16, when the primary screw rod 16 rotates, the threaded sleeve 28 will move forward along the primary screw rod 16. In addition, because the front frame plate 21 is hinged to the secondary hinge seat 26 on the front side fixing plate 12 through the secondary hinge rod 25, the primary hinge rod 23 below the front frame plate 21 and the rear frame plate 22 is hinged through the primary hinge shaft 24, and the secondary hinge rod 25 at the rear center position of the lower end surface of the rear frame plate 22 is hinged to the secondary hinge seat 26 on the threaded sleeve 28, so that the threaded sleeve 28 will arch the front end of the rear frame plate 22 upward during the forward movement, and the rear frame plate 22 drives the rear end of the front frame plate 21 to arch upward, thereby driving the patient's knee joint upward. The front frame plate 21 and the rear frame plate 22 are arched upward, and then the output shaft of the motor 11 is controlled to reverse and drive the threaded sleeve 28 to move backward, thereby driving the front frame plate 21 and the rear frame plate 22 to fall back, and then driving the patient's knee joint to fall back, so that the patient's knee joint can be flexed and extended. The arching amplitude of the front frame plate 21 and the rear frame plate 22 can be adjusted according to the patient's condition, thereby improving the rehabilitation effect on the patient. The front end of the rear frame plate 22 will drive the primary collar 19 to slide back and forth on the primary guide rod 18 during the process of arching upward and then falling back downward. The cooperation of the primary collar 19 and the primary guide rod 18 can guide the rear frame plate 22 and improve the stability, thereby preventing the rear frame plate 22 from shaking during the movement. The support 17 provides bearing capacity for the primary screw rod 16 to avoid the primary screw rod 16 The rear end is bent by excessive force, and the ceramic gasket reduces the friction loss between the primary screw 16 and the support 17, thereby increasing the service life of the primary screw 16. The front end of the rubber sleeve 8 is fixedly sleeved on the rear end of the front frame plate 21, and the rear end of the rubber sleeve 8 is fixedly sleeved on the front end of the rear frame plate 22, so that the patient's knee joint can be protected by the rubber sleeve 8 when the front frame plate 21 and the rear frame plate 22 are arched upward. When lifting exercises are required, the transmission shaft 13 is pulled forward to engage the primary bevel gear 41 and the secondary bevel gear 42, and then the connecting sleeve 71 at the front end of the output shaft of the motor 11 is slid forward so that the block 72 at the rear end of the transmission shaft 13 is stuck in the slot 73 of the connecting sleeve 71, thereby completing the fixed connection between the output shaft of the motor 11 and the transmission shaft 13.Then, the connecting sleeve 71 at the rear end of the primary screw rod 16 is slid forward to disengage the connecting sleeve 71 from the block 72 at the front end of the transmission shaft 13, thereby completing the disengagement of the primary screw rod 16 from the transmission shaft 13. Then, the air starter motor 11 drives the transmission shaft 13 to rotate, thereby driving the secondary screw rod 43 to rotate. Since the movable block 44 is threadedly connected to the secondary screw rod 43, the movable block 44 is driven to move upward. During the upward movement of the movable block 44, the rear third-stage hinged rod 31 is first driven to rise, and then the front third-stage hinged rod 31 is driven to rise. Due to the upper limit plate 81 The frame is mounted on the upper end surface of the lower limit plate 82, so that the rear end of the rear frame plate 22 cannot be lifted upward, and the rear end of the front frame plate 21 cannot be bent downward, so that the rear frame plate 22 and the front frame plate 21 can be kept in a straight line, thereby driving the front end of the front frame plate 21 to rotate upward around the secondary hinge seat 26 on the front side fixing plate 12 of the bottom plate 1, thereby driving the patient's thigh and calf to do lifting exercises to improve the rehabilitation effect. In addition, when performing knee flexion exercises, the patient's heel is on the rubber pad 9, and the sole of the foot contacts the front of the movable block 44. The third-level hinged rod 31 is hinged on the third-level hinged seat 3 at the rear side, and the third-level hinged rod 31 is also hinged on the third-level hinged seat 3 at the rear side, and the lower ends of the third-level hinged rods 31 at the front and rear sides are hinged through the third-level hinged shaft 32, and the lower ends of the second-level guide rods 46 are fixedly connected to the second-level collars 47 slidably sleeved on the first-level guide rods 18, so that the rear end of the rear frame plate 22 will drive the movable block 44 to move together when moving forward, and the movable block 44 always keeps a vertical state. After the rear frame plate 22 arches upward, it will form an angle with the movable block 44, so as to flex and extend the ankle joint of the patient, so that The patient can perform ankle flexion and extension exercises while performing knee flexion and extension exercises, thereby improving the effect of rehabilitation exercises. The movable block 44 moves upward along the insert plate 5. Since the cylindrical hole 6 at the lower end of the front side of the insert plate 5 penetrates to the front side of the movable block 44, and there is a gap between the cylindrical holes 6 in the vertical direction, the protrusion 61 in the cylindrical hole 6 is pressed into the cylindrical hole 6 under the action of the spring 62 and then pops out through the cylindrical hole 6 on the front side of the movable block 44, thereby continuously tapping the sole of the patient's foot, achieving the purpose of stimulating acupuncture points, thereby improving the effect of rehabilitation treatment.
