Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an adjustable structure for an ankle brace. Background Art

[0002] An ankle brace is a medical device used to support and protect the ankle area, and is commonly used for treating and preventing ankle injuries. It is usually made of a sturdy material, such as plastic or metal, which can effectively limit the excessive movement of the ankle, help relieve pain and promote recovery. Ankle braces are widely used in the rehabilitation treatment after sprains, strains, fractures, and for the protection of athletes. According to needs, the brace can be adjustable to fit different foot shapes and treatment requirements.

[0003] Chinese Patent with Publication No. CN211409603U discloses an ankle brace for orthopedics, including a footrest and a calf clamp. The middle parts of the front and rear sides of the footrest and the middle parts of the front and rear sides of the calf clamp are both penetrated by a rotating shaft A. A threaded rod is welded on the rotating shaft A of the footrest and the rotating shaft A of the calf clamp. Both groups of threaded rods are inserted into an internal threaded cylinder, and the inner wall of the internal threaded cylinder is threadedly connected to the outer wall of the threaded rod. A fixing buckle A is welded on the front side of the top of the footrest and the front side of the calf clamp facing the footrest. Through the setting of the internal threaded cylinder and the threaded rod, by rotating the internal threaded cylinder, the internal threaded cylinder makes the two groups of threaded rods move along the inner cavity of the internal threaded cylinder through rotation, so that the footrest rotates around the rotating shaft B, and thus the angle between the footrest and the calf clamp can be adjusted, so that the device can be suitable for the use of people with different foot shapes, and at the same time the device can be suitable for the fixation of the ankle at various angles, and thus the device is more suitable for the fixation and support work of the ankle.

[0004] However, the current ankle brace has the following problems: During the use of the ankle brace, at the beginning, the patient needs a higher insole to relieve pressure. As the rehabilitation process progresses, the height of the insole needs to be gradually reduced to restore normal gait and range of motion. However, the insole of this ankle brace is not convenient to adjust the height of the foot during use according to the patient's condition, so it cannot flexibly adjust the support and comfort according to this change, thus affecting the patient's rehabilitation process. Therefore, we propose an adjustable structure for an ankle brace. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an adjustable structure for an ankle brace, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An ankle brace adjustment structure includes a footrest. An L-shaped inner pad is provided inside the footrest. A number of magic tapes are fixed to the outside of the footrest. An adjustment device is provided on the side of the footrest away from the magic tapes. The adjustment device includes a sealed box. The sealed box is fixed to the outer wall of the footrest. A push plate is slidably installed on the inner wall of the sealed box. A first screw block is fixed to the top of the sealed box. A first screw rod is threadedly connected inside the first screw block. The first screw rod penetrates through the top of the sealed box, and the bottom of the first screw rod is rotatably connected to the top of the push plate. A heightening airbag is fixed to the bottom of the inner wall of the footrest, and the footrest is located between the heightening airbag and the L-shaped inner pad. A connecting pipe is fixed to the bottom of the sealed box. One end of the connecting pipe away from the sealed box is fixed to the outer wall of the heightening airbag. The inside of the heightening airbag is communicated with the inside of the sealed box through the connecting pipe. The top of the heightening airbag is provided with an inclined surface that decreases from the heel to the toe. The design of the inclined surface of the heightening airbag can ensure that the patient's heel will be lifted first when the heightening airbag raises the foot. Under the threaded action of the first screw block on the first screw rod, the first screw rod will move downward. The first screw rod pushes the push plate to move downward along the inside of the sealed box. At this time, the air inside the sealed box is input into the heightening airbag through the connecting pipe, and the heightening airbag expands, so as to realize that the heightening airbag adjusts the height of the insole to lift the foot according to the patient's condition.

[0007] According to the above technical solution, an auxiliary device is provided at the adjustment device. The auxiliary device includes a rotating rod. The rotating rod is rotatably installed on the outer wall of the footrest through a bracket. Moving wheels are fixed to both sides of the rotating rod. When the patient uses this ankle brace, the patient can use the moving wheels for auxiliary movement.

[0008] According to the above technical solution, the auxiliary device further includes a hollow plate, a cavity plate, and an annular inclined groove cylinder. The hollow plate is fixed on one side of the L-shaped inner pad close to the inner wall of the footrest. A plurality of air nozzles are evenly and equidistantly fixed on the side of the hollow plate away from the inner wall of the footrest, and the air nozzles penetrate through the L-shaped inner pad. The cavity plate is fixed on the outer wall of the footrest. A hose is fixed on the top of the cavity plate, and one end of the hose away from the cavity plate is fixed on the outer wall of the hollow plate. A folding bladder is fixed on the outer wall of the cavity plate. One end of the folding bladder away from the cavity plate is fixed with a pressing plate, and one end of the pressing plate away from the folding bladder is fixed with a one-way air inlet nozzle. The annular inclined groove cylinder is fixed on the outer wall of the rotating rod. An annular inclined groove is formed on the outside of the annular inclined groove cylinder. A sliding column is fixed on the bottom of the pressing plate, and one end of the sliding column away from the pressing plate is slidably installed in the annular inclined groove of the annular inclined groove cylinder. The inside of the folding bladder is communicated with the inside of the hollow plate through the cavity plate and the hose. The one-way air inlet nozzle is used to control the one-way air intake of the folding bladder. An air outlet valve for controlling the one-way air outlet of the folding bladder is arranged inside the cavity plate. During the movement of the moving wheel, the rotating rod will be driven to rotate, and the rotating rod drives the annular inclined groove cylinder to rotate. Under the restriction of the annular inclined groove of the annular inclined groove cylinder, the annular inclined groove of the annular inclined groove cylinder pushes the sliding column to drive the pressing plate to reciprocally squeeze the folding bladder. The air in the folding bladder is transmitted to the hollow plate through the cavity plate and the hose, and the hollow plate transmits the air to the air nozzles for spraying. The air is sprayed through the air nozzles.

[0009] According to the above technical solution, the auxiliary device further includes a U-shaped frame. The U-shaped frame is fixed on the side of the cavity plate away from the folding bladder. A second screw rod horizontally penetrates and is threadedly connected to the outer wall of the U-shaped frame. A plug disk is fixed on the side of the second screw rod close to the cavity plate. An exhaust hole for accommodating the plug disk is formed on the outer wall of the cavity plate. When the patient does not need the lower legs and feet to be ventilated, rotate the second screw rod. Due to the threaded action between the second screw rod and the U-shaped frame, the second screw rod drives the plug disk to move away from the cavity plate, and the plug disk no longer blocks the exhaust hole of the cavity plate.

[0010] According to the above technical solution, a massage device is provided at the footrest. The massage device includes two oval groove plates, two L-shaped sliding rods, two push rods, a push column, two bump plates, and two T-shaped rods. The two oval groove plates are respectively fixed on both sides of the outer wall of the rotating rod. An oval groove is provided on one side of the two oval groove plates away from each other. One end of the two L-shaped sliding rods is slidably installed on the outer wall of the footrest, and the other end of the two L-shaped sliding rods is slidably installed inside the oval groove of the oval groove plate. The two push rods are respectively fixed on the tops of the two L-shaped sliding rods. The push column is fixed between the tops of the two push rods. The two bump plates are respectively fixed on one side of the L-shaped inner pad close to the inner wall of the footrest. A receiving groove for receiving the bump plate is provided on the outer wall of the footrest. The two T-shaped rods respectively penetrate through both sides of the outer wall of the footrest. A spring is provided between the T-shaped rod and the outer wall of the footrest. The two T-shaped rods are respectively fixed on both sides of one side of the L-shaped inner pad close to the inner wall of the footrest. A semi-circular bump is fixed on the side of the bump plate away from the L-shaped inner pad. The semi-circular bump of the bump plate is located on the movement track of the semi-circular surface of the push column. During the rotation of the rotating rod, the oval groove plate will be driven to rotate. The oval groove of the oval groove plate pushes the L-shaped sliding rod to reciprocate up and down along the outer wall of the footrest. Each time the L-shaped sliding rod moves upward, the L-shaped sliding rod pushes the push rod to drive the push column to reciprocate up and down. Each time the push rod drives the push column to move upward, the push column pushes the semi-circular bump of the bump plate to drive the bump plate to move towards the L-shaped inner pad. The bump plate pushes the L-shaped inner pad to press the patient's calf.

[0011] According to the above technical solution, the push rod includes a telescopic rod, a threaded rod, and a threaded block. The fixed end of the telescopic rod is fixed on the top of the L-shaped sliding rod. The threaded block is fixed outside the fixed end of the telescopic rod. The threaded rod is threadedly connected inside the threaded block. A sleeve plate for restricting the position of the threaded rod is provided on the outer wall of the telescopic end of the telescopic rod. And there is a clearance fit between the threaded rod and the sleeve plate of the telescopic rod. When the patient does not need calf pressing, rotate the threaded rod. Due to the threaded action of the threaded block on the threaded rod, the threaded rod will separate from the threaded block. At this time, the threaded rod no longer restricts the position of the telescopic rod through the threaded block. At this time, the push rod becomes a telescopic state.

[0012] The present invention provides an adjustment structure for an ankle brace. It has the following beneficial effects: (1) Through the setting of the adjustment device in the present invention, the screw rod one, the screw block one, the push plate, and the sealed box cooperate to drive the connecting pipe to input air into the heightening airbag. The heightening airbag expands, so as to realize that the heightening airbag adjusts the insole to heighten the foot according to the patient's situation. Furthermore, it can help the patient maintain a more natural standing posture, reduce the imbalance of the body, and relieve the pressure on the feet and knees.

[0013] (2) Through the setting of the auxiliary device in the present invention, the patient can use the moving wheels for assisted movement. The moving wheels can reduce the gait burden of the patient when using the ankle-foot orthosis, especially when the patient has weak or unstable ankles. At the same time, the moving wheels can also reduce friction and resistance during walking, helping the patient to maintain a more relaxed movement when walking, reducing the pressure on the feet and other joints of the lower limbs, thereby reducing discomfort and pain. At the same time, the moving wheels, rotating rods, annular inclined groove cylinders, sliding columns, and pressing plates cooperate to squeeze the folding bladder. The air in the folding bladder is transmitted to the hollow plate through the cavity plate and the hose. The hollow plate transmits the air to the jet nozzle and sprays it out. By spraying air through the jet nozzle, the air flow around the leg skin can be increased, helping the sweat to evaporate and reducing the probability of sweat accumulating on the leg surface, which can effectively reduce the discomfort caused by sweat accumulation. When the patient does not need ventilation for the lower leg and feet, the air in the folding bladder driven by the screw rod two, U-shaped frame, plug disk, and cavity plate will directly discharge from the exhaust holes of the cavity plate, thus meeting the patient's need for no ventilation for the lower leg and feet.

[0014] (3) Through the setting of the massage device in the present invention, the rotating rod, oval groove disk, L-shaped sliding rod, footrest, push rod, push column, and bump plate cooperate to drive the bump plate to push the L-shaped inner pad to press the patient's lower leg. The pressing can stimulate the muscles and soft tissues of the lower leg. For patients who need to use the ankle-foot orthosis for a long time, it can help relax the muscles and reduce discomfort, especially the fatigue during the rehabilitation process. When the patient does not need lower leg pressing, through the cooperation of the threaded rod, threaded block, and telescopic rod, the push rod becomes in a telescopic state. Thus, when the L-shaped sliding rod drives the push rod to move, the telescopic end of the telescopic rod expands and contracts, and at this time, the push rod will not push the push column upward, and thus can meet the patient's need for no lower leg pressing.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Please refer to Figure 1 - Figure 10, an embodiment of the present invention is: an ankle brace adjustment structure, including a footrest 1, an L-shaped inner pad 2 is arranged inside the footrest 1, several magic tapes 3 are fixed outside the footrest 1, and an adjustment device 4 is arranged on one side of the footrest 1 away from the magic tape 3. The adjustment device 4 includes a sealed box 41, the sealed box 41 is fixed on the outer wall of the footrest 1, a push plate 44 is slidably installed on the inner wall of the sealed box 41, a first screw block 45 is fixed on the top of the sealed box 41, a first screw rod 46 is threadedly connected inside the first screw block 45, the first screw rod 46 penetrates through the top of the sealed box 41, and the bottom of the first screw rod 46 is rotatably connected to the top of the push plate 44. A heightening airbag 43 is fixed at the bottom of the inner wall of the footrest 1, and the footrest 1 is located between the heightening airbag 43 and the L-shaped inner pad 2. A connecting pipe 42 is fixed at the bottom of the sealed box 41, and one end of the connecting pipe 42 away from the sealed box 41 is fixed on the outer wall of the heightening airbag 43. The inside of the heightening airbag 43 is communicated with the inside of the sealed box 41 through the connecting pipe 42. The top of the heightening airbag 43 is arranged as an inclined surface that decreases from the heel to the toe. The design of the inclined surface of the heightening airbag 43 can ensure that the patient's heel will be lifted first when the heightening airbag 43 raises the foot. Through the setting of the above structure, the air inside the sealed box 41 is input into the heightening airbag 43 through the connecting pipe 42, and the heightening airbag 43 expands, so as to realize that the heightening airbag 43 adjusts the height of the insole to raise the foot according to the patient's situation, and further can help the patient maintain a more natural standing posture, reduce the body imbalance, and relieve the pressure on the feet and knees.

[0019] An auxiliary device 5 is arranged at the adjustment device 4. The auxiliary device 5 includes a rotating rod 51. The rotating rod 51 is rotatably installed on the outer wall of the footrest 1 through a bracket. Moving wheels 52 are fixed on both sides of the rotating rod 51. Through the setting of the above structure, the patient can use the moving wheels 52 for auxiliary movement. The moving wheels 52 can reduce the gait burden of the patient when using the ankle brace, especially when the patient has ankle weakness or instability. At the same time, the moving wheels 52 can also reduce the friction and resistance during walking, help the patient maintain a more relaxed movement when walking, relieve the pressure on the feet and other joints of the lower limbs, and thus reduce discomfort and pain.

[0020] The auxiliary device 5 further includes a hollow plate 53, a cavity plate 55, and an annular inclined groove cylinder 57. The hollow plate 53 is fixed on one side of the L-shaped inner pad 2 close to the inner wall of the footrest 1. A plurality of jet nozzles 511 are evenly and equidistantly fixed on the side of the hollow plate 53 away from the inner wall of the footrest 1, and the jet nozzles 511 penetrate through the L-shaped inner pad 2. The cavity plate 55 is fixed on the outer wall of the footrest 1. A hose 54 is fixed to the top of the cavity plate 55. One end of the hose 54 away from the cavity plate 55 is fixed to the outer wall of the hollow plate 53. A folding bladder 56 is fixed to the outer wall of the cavity plate 55. One end of the folding bladder 56 away from the cavity plate 55 is fixed to a pressure plate 59. One end of the pressure plate 59 away from the folding bladder 56 is fixed to a one-way air inlet nozzle 510. The annular inclined groove cylinder 57 is fixed to the outer wall of the rotating rod 51. An annular inclined groove is provided on the outside of the annular inclined groove cylinder 57. A sliding column 58 is fixed to the bottom of the pressure plate 59. One end of the sliding column 58 away from the pressure plate 59 is slidably installed inside the annular inclined groove of the annular inclined groove cylinder 57. The inside of the folding bladder 56 is communicated with the inside of the hollow plate 53 through the cavity plate 55 and the hose 54. The one-way air inlet nozzle 510 is used to control the one-way intake of air into the folding bladder 56. An air outlet valve for controlling the one-way exhaust of the folding bladder 56 is provided inside the cavity plate 55. Through the setting of the above structure, the hollow plate 53 transmits air to the jet nozzles 511 for ejection. By ejecting air through the jet nozzles 511, the air flow around the leg skin can be increased, helping the sweat to evaporate and reducing the probability of sweat accumulating on the leg surface, which can effectively relieve the discomfort caused by sweat accumulation. It should be noted that every time the pressure plate 59 stretches and resets the folding bladder 56, the one-way air inlet nozzle 510 sucks in external air to supplement the air inside the folding bladder 56.

[0021] The auxiliary device 5 further includes a U-shaped frame 512. The U-shaped frame 512 is fixed on the side of the cavity plate 55 away from the folding bladder 56. A second screw rod 513 passes through and is threadedly connected to the outer wall of the U-shaped frame 512 horizontally. A plug disk 514 is fixed to the side of the second screw rod 513 close to the cavity plate 55. An exhaust hole for accommodating the plug disk 514 is provided on the outer wall of the cavity plate 55. When the patient does not need the lower legs and feet to be ventilated, through the setting of the above structure, the plug disk 514 no longer blocks the exhaust hole of the cavity plate 55, so that when the folding bladder 56 is squeezed by the pressure plate 59, the air in the folding bladder 56 will directly be discharged from the exhaust hole of the cavity plate 55, thus meeting the patient's need for non-ventilation of the lower legs and feet.

[0022] When in use, place the patient's foot into the footrest 1, and make the L-shaped inner pad 2 pad under the foot. Fix the footrest 1 on the patient's foot through the magic tape 3. Rotate the first screw rod 46. Under the thread action of the first screw block 45, the first screw rod 46 will move downward. The first screw rod 46 pushes the push plate 44 to move downward along the inside of the sealing box 41. At this time, the air inside the sealing box 41 is input into the heightening airbag 43 through the connecting pipe 42, and the heightening airbag 43 expands, so as to realize that the heightening airbag 43 adjusts the height of the insole according to the patient's condition, and further can help the patient maintain a more natural standing posture, reduce the body imbalance, and relieve the pressure on the feet and knees.

[0023] When the patient uses this ankle-foot orthosis, the patient can use the moving wheels 52 for assisted movement. The moving wheels 52 can reduce the gait burden of the patient when using this ankle-foot orthosis, especially when the patient has ankle weakness or instability. At the same time, the moving wheels 52 can also reduce the friction and resistance during walking, help the patient maintain a more relaxed movement when walking, relieve the pressure on the feet and other joints of the lower limbs, and thus reduce discomfort and pain; during the movement of the moving wheels 52, the rotating rod 51 will be driven to rotate, and the rotating rod 51 drives the annular inclined groove cylinder 57 to rotate. Under the limitation of the annular inclined groove of the annular inclined groove cylinder 57, the annular inclined groove of the annular inclined groove cylinder 57 pushes the sliding column 58 to drive the pressing plate 59 to reciprocally squeeze the folding bladder 56. The air in the folding bladder 56 is transmitted to the hollow plate 53 through the cavity plate 55 and the hose 54. The hollow plate 53 transmits the air to the air jet nozzle 511 for spraying. By spraying air through the air jet nozzle 511, the air flow around the leg skin can be increased, which helps the evaporation of sweat and reduces the probability of sweat accumulating on the leg surface area, and can effectively relieve the discomfort caused by sweat accumulation. It should be noted that when the pressing plate 59 resets and stretches the folding bladder 56 each time, the one-way air inlet nozzle 510 sucks in external air to supplement the air inside the folding bladder 56; when the patient does not need ventilation for the lower leg and feet, rotate the second screw rod 513. Under the thread action between the second screw rod 513 and the U-shaped frame 512, the second screw rod 513 drives the plug disk 514 to move away from the cavity plate 55. The plug disk 514 no longer blocks the exhaust hole of the cavity plate 55, so that when the folding bladder 56 is squeezed by the pressing plate 59, the air in the folding bladder 56 will directly discharge from the exhaust hole of the cavity plate 55, thus meeting the patient's need for no ventilation for the lower leg and feet.

[0024] Please refer to Figure 1 - Figure 10, on the basis of the above embodiments, in another embodiment of the present invention, a massage device 6 is provided at the footrest 1. The massage device 6 includes two oval groove plates 61, two L-shaped sliding rods 62, two push rods 63, a push column 64, two convex plate blocks 65, and two T-shaped rods 66. The two oval groove plates 61 are respectively fixed on both sides of the outer wall of the rotating rod 51. An oval groove is provided on one side of the two oval groove plates 61 away from each other. One end of each of the two L-shaped sliding rods 62 is slidably installed on the outer wall of the footrest 1, and the other end of each of the two L-shaped sliding rods 62 is slidably installed inside the oval groove of the oval groove plate 61. The two push rods 63 are respectively fixed on the tops of the two L-shaped sliding rods 62. The push column 64 is fixed between the tops of the two push rods 63. The two convex plate blocks 65 are respectively fixed on one side of the L-shaped inner pad 2 close to the inner wall of the footrest 1. A receiving groove for receiving the convex plate block 65 is provided on the outer wall of the footrest 1. The two T-shaped rods 66 respectively penetrate through both sides of the outer wall of the footrest 1. A spring is provided between the T-shaped rod 66 and the outer wall of the footrest 1. The two T-shaped rods 66 are respectively fixed on both sides of one side of the L-shaped inner pad 2 close to the inner wall of the footrest 1. A semi-circular convex block is fixed on the side of the convex plate block 65 away from the L-shaped inner pad 2. The semi-circular convex block of the convex plate block 65 is located on the movement track of the semi-circular surface of the push column 64. Through the setting of the above structure, the convex plate block 65 is enabled to push the L-shaped inner pad 2 to press the calf of the patient. The pressing can stimulate the muscles and soft tissues of the calf. For patients who need to use this ankle-foot orthosis for a long time, it can help relax the muscles and reduce discomfort, especially the fatigue during the rehabilitation process.

[0025] The push rod 63 includes a telescopic rod 631, a threaded rod 632, and a threaded block 633. The fixed end of the telescopic rod 631 is fixed on the top of the L-shaped sliding rod 62. The threaded block 633 is fixed outside the fixed end of the telescopic rod 631. The threaded rod 632 is threadedly connected inside the threaded block 633. A sleeve plate for restricting the position of the threaded rod 632 is provided on the outer wall of the telescopic end of the telescopic rod 631, and there is a clearance fit between the threaded rod 632 and the sleeve plate of the telescopic rod 631. When the patient does not need calf pressing, through the setting of the above structure, the push rod 63 is made to be in a telescopic state. Thus, when the L-shaped sliding rod 62 pushes the push rod 63 to move, the telescopic end of the telescopic rod 631 expands and contracts. At this time, the push rod 63 will not push the push column 64 to move upward, and thus the need of the patient not to have calf pressing can be met.

[0026] During use, the rotation of the rotating rod 51 will drive the elliptical groove disk 61 to rotate during the rotation process. The elliptical groove of the elliptical groove disk 61 pushes the L-shaped slide rod 62 to reciprocate up and down along the outer wall of the footrest 1. Each time the L-shaped slide rod 62 moves upward, the L-shaped slide rod 62 pushes the push rod 63 to drive the push column 64 to reciprocate up and down. Each time the push rod 63 drives the push column 64 to move upward, the push column 64 pushes the semi-circular convex block of the convex block plate 65 to drive the convex block plate 65 to move towards the L-shaped inner pad 2. The convex block plate 65 pushes the L-shaped inner pad 2 to press on the patient's calf. The pressing can stimulate the muscles and soft tissues of the calf. For patients who need to use this ankle brace for a long time, it can help relax the muscles and reduce discomfort, especially the fatigue during the rehabilitation process. When the patient does not need calf pressing, rotate the threaded rod 632. Due to the thread action of the threaded block 633 on the threaded rod 632, the threaded rod 632 will separate from the threaded block 633. At this time, the threaded rod 632 no longer restricts the position of the telescopic rod 631 through the threaded block 633. At this time, the push rod 63 becomes in a telescopic state. Therefore, when the L-shaped slide rod 62 pushes the push rod 63 to move, the telescopic end of the telescopic rod 631 expands and contracts. At this time, the push rod 63 does not push the push column 64 upward, and thus the need of the patient not to have calf pressing can be satisfied.

[0027] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
