The utility model provides an ankle joint trainer please combine and refer to fig. 1 and fig. 2, and ankle joint trainer includes:

a mounting frame 10;

a driving device 20 fixed on the mounting frame 10;

a screw assembly (not shown) including a screw 31, the screw 31 being disposed across a driving shaft of the driving device 20, the screw assembly being fixed to the driving shaft of the driving device 20;

the nut assembly 40 comprises a nut 41, and the nut 41 is sleeved on the screw rod 31; and

the sole fixing component 50 is used for fixing a sole, one end of the sole fixing component 50 is rotatably connected with the mounting rack 10, and the other end of the sole fixing component 50 opposite to the nut component 40 is rotatably connected with the nut component 40.

In the embodiment of the present invention, the mounting frame 10 is substantially i-shaped for mounting other components. Of course, in other embodiments, the mounting frame 10 may have other shapes, such as a square frame shape.

The drive device 20 is fixed to the mounting frame 10, the drive device 20 has a drive shaft which can be rotated by the drive device 20 and which has an axis of rotation. The screw assembly is fixed on the driving shaft of the driving device 20, and the driving shaft of the driving device 20 rotates, so that the screw assembly is driven to rotate.

In one embodiment, the screw assembly further comprises a connecting structure, which connects the screw 31 and the driving device 20, respectively. In one embodiment, the screw 31 is directly fixed to the driving device 20. Likewise, in one embodiment, the nut assembly 40 includes mounting structures that respectively couple the nut 41 and the ball securing assembly 50. In one embodiment, the nut 41 is directly connected to the sole securing assembly 50.

The screw 31 is elongated and the length direction thereof intersects with the driving shaft of the driving device 20, i.e. the axial direction of the screw 31 is not parallel to the rotation axis of the driving device 20, so that when the position of the nut 41 on the screw 31 is changed, the radial distance between the nut 41 and the rotation axis of the driving device 20 is changed, i.e. the rotation radius of the nut 41 is changed, and thus the rotation radius of the sole fixing component 50 is changed, and the rotation amplitude of the sole fixing component 50 is changed. In the present embodiment, the radial distance between the nut 41 and the rotation axis of the driving device 20 refers to a distance in the radial direction along the rotation axis of the driving device 20.

The radial distance between the nut 41 and the rotation axis of the driving device 20 can be changed in various ways, for example, in an embodiment, when the screw 31 is rotated, the axial direction of the screw 31 is not displaced, and when the nut 41 is limited from rotating in the circumferential direction, the nut 41 is displaced along the axial direction of the screw 31, and the radial distance between the nut assembly 40 and the rotation axis of the driving device 20 is changed, so as to change the rotation amplitude of the sole fixing assembly 50. In one embodiment, the screw 31 is fixed, the screw 31 is not displaced in the circumferential direction and the axial direction, and the nut 41 can rotate along the circumferential direction of the screw 31, so as to change the position of the screw on the screw 31, and further change the rotation amplitude of the sole fixing component 50. In an embodiment, the screw 31 slides relative to the driving device 20, and the screw 31 moves along its own axis, which also moves the nut 41, changing the radial distance between the nut 41 and the rotation axis of the driving device 20.

The sole fixing component 50 is elongated and extends in a substantially transverse direction, and optionally, an end of the sole fixing component 50 away from the driving device 20 is at a height equal to the rotation axis of the driving device 20. As such, when the nut 41 is coaxial with the rotational axis of the drive device 20, the sole fixing assembly 50 extends in a horizontal direction; when the nut 41 is misaligned with the rotational axis of the driving device 20, the ball fixing assembly 50 is inclined at a certain angle in the lateral direction. Of course, in other embodiments, the end of the sole fixing component 50 away from the driving device 20 may be lower or higher than the rotation axis of the driving device 20.

Specifically, the sole is placed on the sole fixing member 50 and fixed to the sole fixing member 50. The drive device 20 drives the screw assembly to rotate with the nut assembly 40. since the nut assembly 40 is eccentrically disposed with respect to the rotational axis of the drive device 20, the sole fixing assembly 50 necessarily follows the rotation of the nut assembly 40. Since one end of the sole fixing member 50 is rotatably connected to the mounting frame 10 and the other end is rotatably connected to the nut member 40, the sole fixing member 50 itself does not turn over, and the patient's sole can basically keep the shape of the patient's sole facing upward, i.e., the sole fixing member 50 performs a plate motion about the patient's heel as an axis, thereby preventing the ankle of the patient from being sprained. In addition, as the position of the nut component 40 in the axial direction of the screw component is adjustable, the radial distance between the nut component 40 and the rotation axis of the driving device 20 can be changed, so that the swing amplitude of the sole fixing component 50 is changed along with the eccentric degree of the nut component 40, the farther the nut component 40 is laterally deviated from the rotation axis of the driving device 20, the larger the swing amplitude of the sole fixing component 50 is, the closer the nut component 40 is laterally deviated from the rotation axis of the driving device 20, and the smaller the swing amplitude of the sole fixing component 50 is, thereby meeting the requirements of training intensity of different patients. Because the sole fixing component is driven by the driving device when rotating, the sole fixing component has the effect of force balance compared with a manual mode.

In one embodiment, the screw assembly further comprises an adjusting member 32, the adjusting member 32 is connected to the driving device 20, and the screw 31 is rotatably connected to the adjusting member 32 so that the nut 41 moves along the screw 31 when rotating relative to the adjusting member 32. In this embodiment, the screw 31 is fixed to the driving device 20 through the adjusting member 32, so as to facilitate the installation of the screw 31. The adjusting member 32 axially limits the screw 31 and limits the screw 31 from moving axially. When the screw 31 rotates relative to the adjusting member 32, the nut 41 moves along the screw 31, thereby changing the swing amplitude of the sole fixing component 50.

Alternatively, the adjusting member 32 may be in the form of a plate, a block, or a disk, and one end of the screw 31 abuts against the adjusting member 32, so as to axially limit the screw 31. The adjusting member 32 may have a frame shape, a box shape, or the like, and the screw 31 is disposed inside the adjusting member 32, and both ends of the screw 31 are rotatably connected to the adjusting member 32.

Referring to fig. 3, in order to prevent the nut 41 from rotating, in an embodiment, the adjusting member 32 is formed with a limiting opening 323, the limiting opening 323 extends along the axial direction of the screw 31, the nut component 40 extends from the limiting opening 323, and a side edge of the limiting opening 323 (referring to a side edge extending along the length direction of the screw 31) is used to limit the rotation of the nut component 40. Specifically, the nut component 40 is in close clearance fit with the side edges of the limiting opening 323, or the nut component 40 is in transition fit with the side edges of the limiting opening 323, when the screw 31 rotates, the nut component 40 abuts against at least one side edge of the limiting opening 323, so that the rotation of the nut component 40 is limited, and the nut component 40 only performs the translational motion along the axial direction of the screw 31. In addition, since the nut assembly 40 passes through the limiting opening 323, the screw 31 is obviously disposed corresponding to the limiting opening 323.

In the embodiment of the present invention, the form of the limiting opening 323 formed on the adjusting member 32 has a plurality of forms, and the following simple examples are illustrated:

in an embodiment, the adjusting member 32 includes two connecting plates 321 and two limiting plates 322, the limiting plates 322 extend along the axial direction of the screw 31, the two limiting plates 322 are arranged at intervals along the circumferential direction of the screw 31, the connecting plates 321 are respectively connected to the two limiting plates 322, the two connecting plates 321 are respectively disposed at two ends of the limiting plates 322, and thus the two connecting plates 321 and the two limiting plates 322 are connected to form a similar square frame shape. In this embodiment, the screw 31 is located between the two limit plates 322 and is rotatably connected to the connecting plate 321. The spacing between the two limiting plates 322 forms the limiting opening 323, when the screw 31 rotates, the nut assembly 40 can abut against the limiting plates 322, and the limiting plates 322 limit the rotation of the nut assembly 40.

In one embodiment, the limiting opening 323 extends through two opposite sides of the adjusting member 32, the screw 31 is disposed on one side of the adjusting member 32, and the screw 31 is opposite to the limiting opening 323, i.e., the limiting opening 323 is viewed from the other side of the adjusting member 32, and the screw 31 can be exposed in the limiting opening 323.

In one embodiment, the adjusting member 32 has a long groove formed therein, the long groove extends along the axial direction of the screw 31, the screw 31 is disposed in the long groove, the long groove has a lateral opening, the lateral opening is located on the peripheral side of the screw 31, and the lateral opening forms the limiting opening 323. In one embodiment, the adjusting member 32 is provided with two positioning plates, the two positioning plates are spaced apart from each other, and the spacing between the two positioning plates forms the limiting opening 323.

Referring to fig. 1 and fig. 2 again, in order to prevent the screw 31 from moving along its own axial direction, in an embodiment, the screw assembly further includes two bearings 33, the screw 31 is fixed to an inner ring of the bearing 33, the two bearings 33 are respectively disposed at two ends of the screw 31, and an outer ring of the bearing 33 is fixed to the adjusting member 32. Specifically, two of the connecting plates 321 are respectively provided with a bearing 33, the screw 31 is fixed with an inner ring of the bearing 33, and the inner ring of the bearing 33 is tightly matched with the screw 31, so that the screw 31 can be limited from moving along the axial direction of the screw. In addition, the form of the bearing 33 can avoid abrasion to the connecting plate 321 as opposed to directly rotationally connecting the screw 31 to the connecting plate 321.

In one embodiment, a limiting flange is disposed on the periphery of the screw 31 near each of the two ends, and the limiting flange abuts against the inner surface of the connecting plate 321, so as to limit the axial movement of the screw 31. In the embodiment in which the screw 31 penetrates the connection plate 321, the stopper flange may abut against the outer surface of the connection plate 321. In this embodiment, the inner surface of the connecting plate 321 refers to the surface of the two connecting plates 321 facing each other.

In order to facilitate the adjustment of the screw 31, the screw 31 is extended out of the adjusting member 32, and specifically, in one embodiment, the screw 31 is extended out of the two connecting plates 321, so that the screw 31 can be exposed out of the connecting plates 321 for the user to hold. In addition, one end of the screw 31 can be provided with an adjusting knob 34, the adjusting knob 34 is fixed with the screw 31, and a user can drive the screw 31 to rotate by rotating the adjusting knob 34. Alternatively, the screw 31 may be located in the two connecting plates 321.

In one embodiment, the screw 31 is perpendicular to the driving shaft of the driving device 20, so as to avoid the phenomenon that the nut 41 is always concentric with the rotation axis of the driving device 20 due to the fact that the screw 31 is concentric with the rotation axis of the driving device 20. Alternatively, the screw 31 extends in a radial direction of the rotation axis of the driving device 20, and after the screw 31 is rotated once, the displacement of the nut 41 in the radial direction of the rotation axis of the driving device 20 is maximum, so that the purpose of quick adjustment can be achieved. Of course, the axial direction of the screw 31 may also be arranged crosswise to the radial direction of the rotation axis of the drive means 20.

Further, the screw assembly further comprises a rotating disc 35, and the rotating disc 35 is fixed with the driving device 20. In this embodiment, the turntable 35 is substantially circular and concentric with the rotation axis of the driving device 20, so that the turntable 35 rotates more stably and the shaking of the turntable 35 during rotation can be reduced. The tight fit between the turntable 35 and the drive shaft of the drive device 20 prevents relative rotation between the turntable 35 and the drive shaft of the drive device 20. Optionally, the adjusting member 32 is fixed on a surface of the rotating disc 35 facing away from the driving device 20, so that the rotating disc 35 plays a certain role in supporting and fixing the adjusting member 32, and the shaking of the adjusting member 32 can be greatly reduced when the driving shaft of the driving device 20 rotates. Optionally, the adjusting member 32 is attached to the rotating disc 35 and extends along the disc surface of the rotating disc 35, so that the stability of the adjusting member 32 during rotation can be further enhanced.

In the above embodiment, the ankle joint training device further includes a kit 36, a via hole is provided on the kit 36, a circle of convex ring is provided on the periphery of the via hole, the convex ring extends into the central hole of the rotating shaft and is tightly matched with the central hole to prevent relative rotation between the two.

In this embodiment, the nut frame 42 is provided to facilitate the connection between the nut assembly 40 and the sole fixing assembly 50. In addition, since the nut holder 42 is provided with the relief hole 4221 for the screw rod 31 to penetrate through, the nut holder 42 is well prevented from separating from the screw rod 31. Specifically, the nut 41 and the nut holder 42 may be fixed by welding, and the nut 41 and the nut holder 42 may be engaged with each other, for example, a groove is formed in the nut holder 42, the opening of the groove is directed toward the peripheral side of the screw rod 31, and the nut 41 is fitted into the groove.

And since the connecting shaft 423 is connected with the sole fixing component 50, obviously, the sole fixing component 50 is necessarily larger than the connecting hole 4211, so that the connecting shaft 423 can be limited to move in a direction away from the sole fixing component 50. In this embodiment, the connecting shaft 423 is connected to the first gimbal 71 and is connected to the sole fixing unit 50. The sole fixing assembly 50 is connected by the connection shaft 423, which has a simple structure.

After the sole support frame 12 is provided, when the eccentric distance of the nut assembly 40 relative to the rotation axis of the driving device 20 is adjusted, the sole support frame 12 can adapt to the change of the eccentric distance through swinging, so that the sole fixing assembly 50 can move stably, and the sole support frame 12 can be kept in a stable upward state because both ends of the sole fixing assembly 50 are rotatably connected with other components. When training, the patient's sole uses the heel to carry out about the axle direction wobbling about, stretches the ankle at the swing in-process, prevents the ankle upset, realizes the rehabilitation training effect.
