Description

Technical Field

[0001] This utility model belongs to the field of joint rehabilitation training technology, and in particular relates to an auxiliary device for joint rehabilitation training. Background Technology

[0002] Joint rehabilitation training is an important means to help restore joint function, reduce pain, and enhance joint stability. It is applicable to various conditions such as arthritis, sports injuries, and postoperative recovery. A variety of assistive devices are commonly used in joint rehabilitation training to help patients better perform rehabilitation exercises and improve rehabilitation outcomes. The seated ankle trainer plays a crucial role in joint rehabilitation training, primarily for the rehabilitation of ankle flexion and extension dysfunction. Patients can selectively perform active and passive exercises, gradually increasing ankle flexion and extension capabilities by adjusting the resistance and angle of the trainer. Training with a seated ankle trainer can stimulate the contraction and relaxation of the muscles around the ankle joint, providing comprehensive muscle stimulation and thus enhancing ankle strength and stability. This is of great significance for preventing sports injuries and improving athletic performance.

[0003] The problem with existing technologies is that ankle training requires proper biomechanical alignment to ensure effective muscle and joint engagement. A fixed distance may prevent patients from maintaining the correct posture during training, thus affecting the training effect. Utility Model Content

The driven gear 804 and the drive gear 803 are meshed together.

[0027] The above solution is adopted: by setting the drive structure 8, the screw 10 can be driven to rotate, and the screw 10 can be driven to move the threaded moving block 11.

[0028] refer to Figure 2 The screw 10 is threadedly connected to the moving block 11, and the moving block 11 is slidably connected to the inside of the groove 9. The top of the moving block 11 is fixedly connected to the drive box 12. The front and rear sides of the drive box 12 are rotatably connected to the rotating rod 13. The surface of the rotating rod 13 is fixedly connected to the connecting block 13. The top of the connecting block 14 is fixedly connected to the rear foot pad 15.

A compression spring 2105 is sleeved on the surface of the limiting rod 2104, and the two ends of the compression spring 2105 are fixedly connected to the surface of the connecting rod 2102 and the surface of the cross frame 6, respectively. A protective cover 2106 is fixedly connected to the left side of the drive box 12, and the protective cover 2106 covers the plug-in structure 21.

[0037] The above solution is adopted: by setting the plug-in structure 21, the limiting hole 20 can be plugged in, thereby improving the stability of the drive box 12 in the cross frame 6.

[0038] The working principle of this utility model:

[0039] In use, the motor 802 is started, which drives the drive gear 803 to rotate. The drive gear 803 drives the meshing driven gear 804 to rotate, which in turn drives the screw 10 to move. When the screw 10 rotates, it drives the threaded moving block 11 to move. Then, the moving block 11 drives the drive box 12 to adjust its position. After adjusting to the appropriate position, the electric cylinder 2101 is started. The electric cylinder 2101 drives the connecting rod 2102 to move downward. The connecting rod 2102 drives the insert 2103 to move downward and insert into the limiting hole 20. At this time, the position of the drive box 12 can be positioned. Then, the knob 18 can be rotated. The rotation of the knob 18 drives the transmission rod 1603 to rotate, which adjusts the position of the first positioning block 1602. This allows the position of the front foot pad 17 to be adjusted until it is adjusted to the size suitable for the patient's foot. At this time, the user can make circular motions on the rear foot pad 15 and the front foot pad 17.

[0040] In summary, this auxiliary device for joint rehabilitation training, through the coordinated use of a power box 1, extension frame 2, crossbar 3, round rod 4, seat 5, cross frame 6, cavity 7, drive structure 8, groove 9, screw 10, moving block 11, drive box 12, rotating rod 13, connecting block 14, rear foot pad 15, connecting structure 16, front foot pad 17, knob 18, limiting plate 19, limiting hole 20, and plug-in structure 21, solves the problem that ankle joint training requires proper biomechanical alignment to ensure effective muscle and joint participation, and that a fixed distance may prevent patients from maintaining the correct posture during training, thus affecting the training effect.
