Description

Technical Field

[0001] This utility model relates to the field of joint exercise instruments, specifically to an orthopedic joint exercise instrument. Background Technology

[0002] For patients with muscle atrophy or joint injuries, appropriate rehabilitation training is needed to strengthen the joints and improve the rehabilitation effect.

[0003] Currently, existing rehabilitation training technologies require manual stretching of the corresponding joints or the use of medical joint rotation exercise rehabilitation devices. While these devices can provide medical assistance to patients, they are complex to operate, have intricate structures, and require time and effort for manual rehabilitation. Furthermore, the intensity of the training is difficult to control, resulting in a significant workload for medical staff. This is a shortcoming of existing technologies. Utility Model Content

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0017] This invention utilizes a combination structure of a drive assembly, a leg-side assembly, an adjustment assembly, and a thigh-side assembly. The user can lie between the mounting frames, with their waist in contact with the thigh-side assembly and their legs aligned with it. The front and rear sleeves provide positioning. By cranking the eccentric handle, the front wheel rotates, which in turn drives the rear wheel via a belt. The connecting shaft and drive gear rotate, and the meshing of the drive and driven gears moves the sleeve block along the threaded rod. A hinge support drives the top bottom rod (rear bottom rod) to deflect. During movement, the top of the rear bottom rod is movable relative to the telescopic rod via a hinge support and a pin. Since both ends of the front bottom rod are also movable, the thigh-side assembly can deflect around the front shaft and lie flat during the movement of the bottom structure. Therefore, the user can adjust the exercise angle according to their own needs. The entire process is manually belt-driven, making it convenient for single-person use.

[0018] In this device, when the outer driving tooth rotates, it can drive the threaded rod to rotate through its meshing with the driven tooth, thereby driving the sleeve block structure that meshes with it to move back and forth on the threaded rod, realizing the functions of position adjustment and angle adjustment.

[0019] In this device, the front base rod structure is connected by a pin and a telescopic rod. The telescopic rod structure can be locked in different positioning holes by the pin, allowing the user to adjust it according to their own body shape, meeting the usage requirements of different people and expanding the applicability of this device.

[0020] In this device, the user can fix the mounting bracket to the ground, or to a wall or a slope at a specified angle. The user can exercise while lying down or while standing. Attached Figure Description

The bottom end of the telescopic rod 34 is fixed with a pin 321, and the telescopic rod 34 is locked in the positioning hole 311 by the pin 321. In this device, when the outer active tooth 361 rotates, it can drive the threaded rod 52 to rotate through its meshing with the driven tooth 521, thereby driving the sleeve block 53 structure that meshes with it to move back and forth on the threaded rod 52, realizing the functions of position adjustment and angle adjustment.

[0034] The leg-side assembly 4 includes a rear base rod 41, a rear top rod 42 fixed to the top of the rear base rod 41, and a bottom rod 44 fixed to the bottom of the rear base rod 41. A hinge support 47 is fixed to the bottom end of the bottom rod 44. The rear end of the rear base rod 41 is fixedly connected to the foot plate 46 through a connecting plate 45. The bottom end of the bottom rod 44 is connected to the drive assembly 2 through an adjustment assembly 5. A front sleeve 33 and a rear sleeve 43 are respectively sleeved between the rear top rods 42 and between the front top rods 32. The hinge support 47 is connected to another set of structures through a pin 321 and a nut. In this device, the front base rod 31 is sleeved and connected to the telescopic rod 34 through a pin 321. The telescopic rod 34 can be locked in different positioning holes 311 through the pin 321. Users can adjust it according to their own body shape to meet the usage requirements of different people and expand the applicability of this device.

[0035] The adjustment assembly 5 includes two sets of bearing seats 51 and threaded rods 52. The top ends of the mounting frame 1 and the crossbar 11 are both fixed with bearing seats 51.
