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 transmission assembly (not shown) fixed to a drive shaft of the drive device 20; and

the sole fixing assembly 50 is used for fixing a sole, one end of the sole fixing assembly 50 is connected with the transmission assembly through a first universal joint 71, and the other end of the sole fixing assembly 50 is rotatably connected with the mounting rack 10 through a second universal joint 72.

In the embodiment of the present invention, the mounting frame 10 is substantially a frame structure for mounting other components. For example, the mounting bracket 10 is generally i-shaped, etc., although in other embodiments, the mounting bracket 10 may have other shapes, such as square, etc.

The driving device 20 is fixed to the mounting frame 10, specifically by means of screws. For example, the mounting frame 10 is formed with a transverse support plane on which the drive means 20 rest directly. Alternatively, the driving device 20 is fixed to a side of the mounting frame 10.

The drive device 20 has a drive shaft which can be rotated by the drive device 20, the drive shaft having an axis of rotation. The transmission assembly is fixed on the driving shaft of the driving device 20, and the driving shaft of the driving device 20 rotates to drive the transmission assembly to rotate.

At least, one end of the sole fixing component 50 close to the driving device 20 is offset from the axis of the driving shaft, so that when the driving shaft rotates, the sole fixing component 50 can move along with the driving shaft and can generate displacement in the up-down, left-right directions. Specifically, one end of the sole fixing assembly 50 close to the driving device 20 is always staggered from the axis of the driving shaft; alternatively, where a radial adjustment mechanism is provided, the radial adjustment mechanism may adjust the sole securing assembly 50 to be offset from the drive shaft, and the radial adjustment mechanism may also adjust the sole securing assembly 50 to be aligned with the drive shaft.

Specifically, the sole is placed on the sole fixing member 50 and fixed to the sole fixing member 50. The driving device 20 drives the transmission assembly to rotate, and the sole fixing assembly 50 also rotates along with the transmission assembly. Because one end of the sole fixing component 50 is connected with the transmission component through the first universal joint 71, and the other end is rotatably connected with the mounting rack 10 through the second universal joint 72, when the sole fixing component 50 rotates, the sole fixing component 50 does not turn over, and the sole of the patient can basically keep the shape of the upward sole surface, so that the sole fixing component 50 moves stably, the stress of the patient is balanced, and the treatment effect is better.

In one embodiment, the transmission assembly comprises a radial adjustment mechanism and a connecting member 423, the radial adjustment mechanism connects the driving device 20 and the connecting member 423 respectively, the connecting member 423 connects the first universal joint 71, and the radial adjustment mechanism can adjust the position of the connecting member 423 in the radial direction of the driving shaft. Specifically, since the radial distance of the connecting element 423 relative to the driving shaft is adjustable, the swing amplitude of the sole fixing component 50 connected to the connecting element 423 can be changed, so that the swing amplitude of the sole fixing component 50 changes along with the eccentricity degree (referred to as the deviation from the axis of the driving shaft) of the connecting element 423, the farther the connecting element 423 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 connecting element 423 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.

In one embodiment, the radial adjustment mechanism is provided with a connection hole 4211 (as shown in fig. 4), the connection member 423 is in an elongated shape, a limit shoulder 4231 is arranged on the outer periphery of the connection member 423, the connection member 423 penetrates through the connection hole 4211, one side of the limit shoulder 4231, which is away from the driving device 20, abuts against the radial adjustment mechanism to limit the connection member 423 from moving in a direction away from the driving device 20, and one end of the connection member 423, which is away from the driving device 20, is provided with the first universal joint 71. The attachment of the connecting member 423 has a simple and reliable effect.

In the embodiment of the present invention, the form of the radial adjusting mechanism has multiple types, and the following is specifically described with respect to several types thereof, but not limited thereto:

in the first embodiment, the radial adjusting mechanism includes a screw 31 assembly and a nut assembly 40, the screw 31 assembly is fixed to the driving shaft, the screw 31 assembly includes the screw 31, the nut assembly 40 is connected to the connecting member 423, the nut assembly 40 includes a nut 41, and the nut 41 is sleeved on the screw 31.

The screw 31 is elongated and the length direction thereof is arranged crosswise relative to 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 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 driving device 20 drives the screw assembly 31 and the nut assembly 40 to rotate together, and the sole fixing assembly 50 necessarily follows the nut assembly 40 to rotate because the nut assembly 40 is eccentrically arranged relative to the rotation axis of the driving device 20. 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 axial position of the nut component 40 relative to the screw rod 31 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 swinging 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 swinging 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 swinging amplitude of the sole fixing component 50 is, thereby meeting the requirements of training intensity of different patients.

In one embodiment, the screw 31 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.

In order to prevent the screw 31 from moving along its own axis, in an embodiment, the screw 31 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 31 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 one embodiment, the adjusting member 32 is fixed to the rotating disc 35 by screws. In addition, the adjusting member 32 and the rotating disk 35 may be fixed by welding or the like.

Referring to fig. 4, in an embodiment, the nut assembly 40 further includes a nut frame 42, the nut 41 is fixed on the nut frame 42, the nut frame 42 is provided with a relief hole 4221, the screw 31 passes through the relief hole 4221, and the nut frame 42 is connected to the sole fixing assembly 50. 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.

In one embodiment, the nut holder 42 includes a first fixing plate 421 and two second fixing plates 422, the two second fixing plates 422 are arranged at intervals along an axial direction of the nut 41, the two second fixing plates 422 are respectively connected to the first fixing plate 421, the nut 41 is located between the two second fixing plates 422 and fixed to one of the second fixing plates 422, the two second fixing plates 422 are both provided with the abdicating hole 4221, and the first fixing plate 421 is connected to the sole fixing component 50.

In one embodiment, a connection hole 4211 is formed in the first fixing plate 421, the connection member 423 extends between the two second fixing plates 422, the connection member 423 passes through the connection hole 4211 to be fixed to the first universal joint 71, and the limiting shoulder 4231 abuts against a surface of the first fixing plate 421, which is away from the sole fixing component 50, so as to limit the connection member 423 from moving toward the sole fixing component 50. And since the sole fixing assembly 50 is connected to the connection member 423, it is apparent that the sole fixing assembly 50 is necessarily larger than the connection hole 4211, so that the connection member 423 is restricted from moving in a direction away from the sole fixing assembly 50. The sole fixing assembly 50 is connected by the connecting piece 423, which has a simple structure.

Alternatively, in other embodiments, the connecting member 423 can be integrally formed with the nut bracket 42, and the connecting member 423 can be a part of the nut bracket 42 and directly rotatably connected to the sole plate fixing component 50. In addition, in other embodiments, the nut bracket 42 may be provided with a rotation hole for rotatably connecting with the rotation shaft of the sole fixing component 50.

Alternatively, the axial direction of the coupling hole 4211 is along the axial direction of the driving shaft, which may improve the driving effect.

The sole support 52 and the sole connecting support 51 can be fixed by means of adhesion, clamping, hook and loop fasteners, or a bandage. Typically, the sole support 52 is a soft or elastic member to enhance cushioning. The patient's sole may be attached to the sole support 52 by a strap.

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. In other embodiments, the rotation direction of the sole support frame 12 may also coincide with the rotation direction of the driving shaft of the driving device 20.

In one embodiment, the bottom frame 11 is provided with two mounting plates, the two mounting plates are arranged at a distance along the transverse direction, the two mounting plates are provided with rotating shafts, and the sole support 12 extends between the two mounting plates and is connected with the rotating shafts so as to realize relative rotation with the bottom frame 11.
