Description

Technical Field

[0001] This utility model relates to the field of Achilles tendon protection devices, and more specifically, to wearable devices with Achilles tendon protection function. Background Technology

[0002] When a person stands on their toes with their heels off the ground, there is a thick, strong, and taut tendon between the heel and the lower leg—this is the Achilles tendon. It is formed by the tendon of the soleus muscle, which originates from the back of the tibia, and the gastrocnemius muscle, which originates from the medial and lateral condyles of the femur. It is one of the strongest tendons in the human body. Walking, running, and jumping all rely on this powerful tendon. If the Achilles tendon is completely ruptured, walking becomes impossible. The Achilles tendon is about 15cm long and is the thickest tendon in the human body. Its main functions are flexion of the lower leg and plantar flexion of the foot; it is what enables a person to jump and run. Furthermore, the Achilles tendon also affects upright posture. During daily exercise, due to improper force application or other improper exercise factors, Achilles tendon injuries frequently occur, and in severe cases, Achilles tendon rupture can even occur. Achilles tendon rupture is a common tendon injury, and once it occurs, it can significantly impact a person's quality of life and daily work.

[0003] Nowadays, most people protect their Achilles tendons by wearing protective sleeves during exercise. However, for people who have already injured their Achilles tendons, wearing these sleeves still allows for a wide range of plantar flexion and dorsiflexion of the foot, making it difficult to control the angles of plantar flexion and dorsiflexion. If people bend their feet too much, it can easily stretch the Achilles tendon excessively, leading to secondary damage to the Achilles tendon and resulting in poor protection of the tendon, thus reducing its practicality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the problems existing in the prior art, this utility model provides a wearable device with Achilles tendon protection function. This solves the technical problem mentioned in the background art that, when worn by people with Achilles tendon injuries, their feet can still bend to a large extent, making it difficult to control the angle of foot flexion. If people bend their feet to a large extent, it is easy to overstretch the Achilles tendon, leading to secondary damage to the Achilles tendon. As a result, the device has a poor effect on protecting the Achilles tendon, reducing its practicality.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wearable device with Achilles tendon protection function, including a foot pad. Two fixed ears are fixedly connected to the two sides of the heel portion of the foot pad. Vertical plates are rotatably connected to the two fixed ears.

A square tube is fixedly connected to the sides of the two vertical plates. A square column is slidably disposed in the middle of the interior of the square tube. Top columns are fixedly connected to the top and bottom of the square column. Limiting mechanisms are slidably disposed on the upper and lower sides of the interior of the square tube. A first connecting ear is fixedly connected to the side of the square column. A connecting plate is rotatably connected to the first connecting ear. A second connecting ear is rotatably connected to the other end of the connecting plate. The second connecting ear is fixedly connected to the corresponding fixed ear, which facilitates limiting the angle of foot flexion, avoiding excessive tensile stress on the Achilles tendon, preventing secondary injury to the Achilles tendon, facilitating the recovery of the injured Achilles tendon, improving the effectiveness of Achilles tendon protection, and enhancing its practicality.

[0008] The present invention is further configured such that the limiting mechanism includes an adjusting seat, a square groove is provided at the end of the adjusting seat away from the square column, a first square plate and a second square plate are slidably arranged inside the square groove, a compression spring is provided between the first square plate and the second square plate, a first screw is rotatably connected to the side end of the second square plate, a sealing plate is installed on the adjusting seat, the first screw is rotatably connected to the sealing plate, and a circular groove is provided at the end of the adjusting seat near the square column to facilitate limiting the stroke of the square column.

[0009] The present invention is further configured such that the diameter of the circular groove is larger than the diameter of the top column, so that the top column can be inserted into the interior of the square groove through the circular groove.

[0010] The present invention is further configured such that a first throttle is fixedly connected to the side end of the first screw, which facilitates the rotation of the first screw.

[0011] The present invention is further configured such that a plurality of threaded holes are evenly provided on the square tube, a fixing groove is provided on the side end of the adjusting seat, a second screw is threadedly connected to the internal thread of the threaded hole corresponding to the fixing groove, and a fixing post adapted to the fixing groove is fixedly connected to the side end of the second screw, so as to facilitate the fixing of the adjusting seat.

[0012] The present invention is further configured such that a second throttle is fixedly connected to the side end of the second screw, which facilitates the rotation of the second screw.

[0013] The present invention is further configured such that a strip groove is provided on the side end of the square tube, and the first connecting ear is located inside the strip groove to ensure that the first connecting ear slides up and down.

[0014] The present invention is further configured such that the heel part of the foot pad and the part connected to the multiple fixing straps are made of hard board, and the forefoot position of the foot pad is made of soft pad, which makes it easier for people to bend their forefoot and walk.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a wearable device with Achilles tendon protection function, which has the following beneficial effects:

[0017] 1. During walking, the foot causes the footpad to rotate. The footpad, through the fixed ear and connecting plate, causes the first connecting ear, square post, and two top posts to slide up and down inside the square tube. It slides inside the square tube through the limiting mechanism. According to the usage requirements, the limiting mechanism can be adjusted to a suitable position inside the square tube. The limiting mechanism limits the position of the square post, thereby controlling the range of foot flexion angle. This avoids excessive stretching of the Achilles tendon during plantar flexion and dorsiflexion, prevents secondary injury to the Achilles tendon, facilitates the recovery of the injured Achilles tendon, improves the protection effect of the Achilles tendon, and enhances its practicality.

[0018] 2. By rotating the first screw, the first screw drives the second square plate to move, adjusting the distance between the first and second square plates, adjusting the degree of compression of the compression spring, and adjusting the force of the compression spring on the first square plate. When the top column contacts the first square plate, the compression spring causes the top column and square column to stop slowly, avoiding the square column and top column being stopped abruptly, and at the same time providing a certain degree of protection for the Achilles tendon area.

[0019] 3. By screwing the second screw into the threaded hole corresponding to the fixing groove, and then tightening the second screw, the fixing post is inserted into the fixing groove, so that the adjusting seat is stably fixed in the corresponding position inside the square tube.

[0029] Please see Figures 1-5The wearable device with Achilles tendon protection function includes a foot pad 1. The heel part of the foot pad 1 and the part connected to multiple fixing straps 5 are made of hard board. The forefoot part of the foot pad 1 is made of soft pad to facilitate bending of the forefoot and walking. Both sides of the heel part of the foot pad 1 are fixedly connected to fixing ears 2. Vertical plates 3 are rotatably connected to both fixing ears 2. The rotation axis of the fixing ears 2 and the vertical plates 3 corresponds to the position of the ankle. Multiple curved plates 4 are fixedly connected to the sides of the two vertical plates 3. Fixing straps 5 are fixedly connected to both vertical plates 3 and the foot pad 1. The fixing straps 5 are connected together by Velcro. Two vertical plates 3 are fixedly connected to square tubes 6 at their side ends. A square column 7 is slidably arranged in the middle of the inside of the square tube 6. A top column 8 is fixedly connected to the top and bottom of the square column 7. A limit mechanism is slidably arranged on the upper and lower sides of the inside of the square tube 6. A first connecting ear 9 is fixedly connected to the side end of the square column 7. A strip groove 26 is provided on the side end of the square tube 6. The first connecting ear 9 is located inside the strip groove 26 to ensure that the first connecting ear 9 slides up and down. A connecting plate 10 is rotatably connected to the first connecting ear 9. A second connecting ear 11 is rotatably connected to the other end of the connecting plate 10. The second connecting ear 11 is fixedly connected to the corresponding fixed ear 2.

[0030] Specifically, during walking, the foot causes the footpad 1 to rotate. The footpad 1, through the fixed ear 2 and the connecting plate 10, causes the first connecting ear 9, the square post 7, and the two top posts 8 to slide up and down inside the square tube 6. It slides inside the square tube 6 through the limiting mechanism. According to the usage requirements, the limiting mechanism can be adjusted to a suitable position inside the square tube 6. The limiting mechanism limits the position of the square post 7, thereby controlling the range of foot flexion angle. This avoids excessive stress on the Achilles tendon during plantar flexion and dorsiflexion, prevents secondary injury to the Achilles tendon, facilitates the recovery of the injured Achilles tendon, improves the protection effect of the Achilles tendon, and enhances its practicality.

[0031] Please see Figure 4 The limiting mechanism includes an adjusting seat 12. A square groove 13 is provided at the end of the adjusting seat 12 away from the square column 7. A first square plate 14 and a second square plate 15 are slidably arranged inside the square groove 13. A compression spring 16 is provided between the first square plate 14 and the second square plate 15. A first screw 17 is rotatably connected to the side end of the second square plate 15. A sealing plate 18 is installed on the adjusting seat 12. The first screw 17 is rotatably connected to the sealing plate 18. A circular groove 19 is provided at the end of the adjusting seat 12 near the square column 7. The diameter of the circular groove 19 is larger than the diameter of the top column 8, so that the top column 8 can be inserted into the interior of the square groove 13 through the circular groove 19. A first throttle 20 is fixedly connected to the side end of the first screw 17, so that the first screw 17 can be rotated.

[0032] Specifically, by rotating the first screw 17, the first screw 17 drives the second square plate 15 to move, adjusting the distance between the first square plate 14 and the second square plate 15, adjusting the degree of compression of the compression spring 16, and adjusting the force of the compression spring 16 on the first square plate 14. When the top column 8 contacts the first square plate 14, the compression spring 16 causes the top column 8 and the square column 7 to stop slowly, avoiding the square column 7 and the top column 8 from being stopped abruptly, and at the same time providing a certain degree of protection for the Achilles tendon area.

[0033] Please see Figures 3-5 The square tube 6 is evenly provided with multiple threaded holes 21. The side end of the adjusting seat 12 is provided with a fixing groove 22. The threaded hole 21 corresponding to the fixing groove 22 is internally threaded with a second screw 23. The side end of the second screw 23 is fixedly connected with a fixing post 24 that matches the fixing groove 22, so as to facilitate the fixing of the adjusting seat 12. The side end of the second screw 23 is fixedly connected with a second throttle 25, so as to facilitate the rotation of the second screw 23.

[0034] Specifically, by screwing the second screw 23 into the threaded hole 21 corresponding to the fixing groove 22, and then tightening the second screw 23, the fixing post 24 is inserted into the fixing groove 22, so that the adjusting seat 12 is stably fixed in the corresponding position inside the square tube 6.

[0035] In summary, when using the overall equipment:

[0036] People step on the foot pad 1, with their lower legs in contact with multiple curved plates 4. The foot pad 1 is then secured to the foot via the fixing strap 5, and the two vertical plates 3 and multiple curved plates 4 are fixed to the lower legs. The position of the adjusting seat 12 inside the square tube 6 is adjusted according to the plantar flexion and dorsiflexion angles. Then, the second screw 23 is screwed into the threaded hole 21 corresponding to the fixing groove 22. The second screw 23 is then tightened, causing the fixing post 24 to insert into the fixing groove 22, thus stably fixing the adjusting seat 12 in the corresponding position inside the square tube 6. During movement, the soles of the feet will... When the foot pad 1 bends, the foot pad 1 drives the first connecting ear 9, the square post 7, and the two top posts 8 to slide up and down inside the square tube 6 through the fixed ear 2 and the connecting plate 10. When the top post 8 contacts the first square plate 14, the force of the compression spring 16 increases the resistance to plantar flexion and dorsiflexion of the foot, making it more difficult for the foot to continue to plantar flexion or dorsiflexion. When the foot feels resistance during plantar flexion and dorsiflexion, it prompts the foot to avoid further bending. When the compression spring 16 is compressed to a certain extent, it stops the foot from bending, preventing the foot from reaching the limit of Achilles tendon injury and avoiding secondary Achilles tendon injury.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
