Technical Field

[0001] The utility model relates to the technical field of water exercise rehabilitation, in particular to an water ankle joint trainer capable of adjusting the range of movable angles. Background Art

[0002] The Balance Board is a simple yet effective balance training device. Exercises such as standing and squatting on the board strengthen core muscles and calf and hind legs. Supported by two or one foot, the trainee coordinates their torso and limbs, completing various stability exercises to improve athletic ability.

[0003] Existing balance board training on land requires patients to fully weight-bear on both or one leg. Conventional balance boards place high demands on ankle, hip, and knee joint flexibility, while offering no limits on the range of motion of the lower limb joints. However, patients' joint function often cannot adapt quickly enough to complete such training. Training on existing balance boards can cause pain, which can inhibit training effectiveness. Summary of the Invention

[0031] Below, the embodiments of the present utility model are described in detail with reference to the accompanying drawings.

[0032] Example

[0033] Please refer to Figures 1 to 2 The present embodiment provides an underwater ankle joint trainer with an adjustable range of motion angle, comprising a base 1, a connecting rod 2, a limit pin 3, and a support base 4:

[0034] Side panels 5 are symmetrically provided on both sides of the base 1, and a fixed shaft 6 is provided between the two side panels 5; a plurality of limiting holes 7 are provided at relative positions of the two side panels 5, and the plurality of limiting holes 7 are distributed along an arc;

[0035] One end of the connecting rod 2 is provided with an axial hole, which is rotatably connected to the fixed shaft 6;

[0036] The limit pins 3 are inserted into the corresponding limit holes 7 of the two side plates 5, and the limit pins 3 are used to limit the rotation range of the connecting rod 2;

[0037] The bottom of the support seat 4 is connected to the top of the connecting rod 2, and the support seat 4 is used to support the sole of the patient's foot.

[0038] In a specific application, the base 1 is a rectangular flat plate, and the side plates 5 are semicircular plates. The base 1 and the side plates 5 can be made of aluminum, which has good strength and is not easily corroded in water. The base 1 and the side plates 5 can be manufactured in one process.

[0039] The plurality of limiting holes 7 are distributed along the arc and symmetrically on both sides. The distance between two adjacent limiting holes 7 is set according to the needs of rehabilitation training.

[0040] There are two limit pins 3 , which can be respectively inserted into the limit holes 7 on both sides of the connecting rod 2 , thereby limiting the forward and backward rotation angle range of the connecting rod 2 .

[0041] The connecting rod 2 is located at the bottom center of the support base 4, and the support base 4 and the connecting rod 2 are fixedly connected by welding.

[0042] The connecting rod 2, the limiting pin 3, the supporting seat 4 and the fixed shaft 6 are all made of rust-proof metal materials.

[0043] In this embodiment, the plurality of limiting holes 7 are distributed at uniform angular intervals along the arc.

[0044] In a specific application, the limiting holes 7 are evenly spaced along the arc, and when the rotation range of the connecting rod 2 is adjusted by the limiting pin 3 , the rotation angle range thereof can be well controlled.

[0045] In this embodiment, angle scale lines can be engraved above the upper limit hole 7 on the side plate 5, the zero position scale is located at the vertical center, and the positive and negative angles on both sides are symmetrical. The rotation range of the connecting rod 2 can be clearly known through the angle scale lines.

[0046] In this embodiment, a damper is provided between the fixed shaft 6 and the shaft hole.

[0047] In specific applications, the damper can be an existing product, such as a rotary damper. The damper is mounted on the fixed shaft 6, with the shaft hole connected to the damper's exterior. The damper's specifications are selected based on actual needs. The damper provides resistance. During exercise, the patient's foot rotates around the fixed shaft 6 along with the connecting rod 2. Due to the presence of the damper, a certain amount of force is required to rotate the foot back and forth around the fixed shaft 6, thereby improving the training effect.

[0048] In this embodiment, the support base 4 includes a bottom plate 401 , and a front baffle 402 and a rear baffle 403 are provided at the front and rear ends of the bottom plate 401 .

[0049] In a specific application, the height of the front baffle 402 is lower than that of the rear baffle 403. When the patient's foot steps on the base plate 401, the front baffle 402 can support the toes and the rear baffle 403 can support the heel, thereby preventing the foot from sliding off the support seat 4.

[0050] In this embodiment, a foam board 404 is provided on the base plate 401. The foam board 404 can provide buoyancy in the water. After the support base 4 is tilted, the buoyancy can be used to increase the difficulty of the balance training and assist the support base 4 in returning to the middle position of the trainer. The foam board 404 can be fixed to the base plate 401 by a belt with a buckle. In addition, the foam board 404 of different thicknesses can be replaced as needed to generate different buoyancy levels, thereby creating balance training of different difficulty levels. In this embodiment, the upper surface of the base plate 401 is provided with anti-slip grooves to increase the friction between the sole of the foot and the base plate 401.

[0051] In this embodiment, silicone pads are provided on the upper surface of the bottom plate 401 , the inner side of the front baffle 402 , and the inner side of the rear baffle 403 .

[0052] In specific applications, the silicone pad is soft and can provide comfort for the sole of the foot on the support base 4, while protecting the sole of the foot from damage by the support base 4. The silicone pad on the upper surface of the bottom plate 401 can also be provided with anti-slip grooves.

[0053] In this embodiment, straps are provided on both sides of the bottom plate 401 .

[0054] In a specific application, strap holes are opened on both sides of the bottom plate 401 , and one end of the strap is fixed in the strap hole. The strap can better fix the patient's feet in the support seat 4 .

[0055] The strap can be a magic belt, with a male buckle on one side and a female buckle on the other side. The two are bonded together during use and are easy to disassemble and use.

[0056] Please refer to Figure 3As shown, when the underwater ankle joint trainer with adjustable range of motion angle of this embodiment is used, the rotation angle range of the connecting rod 2 can be adjusted according to the patient's training activity angle by using two limit pins 3; or the patient can make adjustments by cooperating with the limit pins 3 and the limit holes 7 after trying to determine the range of motion angle in a painless state. During training, the trainer is placed in water, the patient's foot to be trained is stepped on the support seat 4, and the other foot stands on a stable surface in the water. The patient exerts force to rotate the foot to be trained back and forth around the fixed axis 6 to perform rehabilitation training. The underwater ankle joint trainer with adjustable range of motion angle of this embodiment is easy to use, can adjust the range of ankle joint motion angles as needed, and can limit the motion angles, allowing patients to train in a painless state and improving the training effect.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
