Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an elastic ankle joint protection device for preventing training injuries. Background Technology

[0002] Training injuries refer to acute or chronic injuries caused by factors such as the body bearing loads exceeding its adaptability, improper movements, environmental factors, or equipment problems during military training, sports training, or high-intensity physical activities. During training, elastic ankle support devices, such as elastic ankle braces, are important equipment for preventing training injuries. They effectively reduce the risk of ankle injury by limiting the range of motion of the foot and ankle, reducing the peak stress of the internal tissues of the joint, buffering vertical impact forces, and reducing ligament tensile loads.

[0003] The prior art, patent number CN214181744U, describes a second fixing strap for a training injury prevention elastic ankle joint protection device. The second strap has a snap-fastener elastic band on one side, and the snap-fastener elastic band is a long rectangular strip. A first hook-and-loop fastener is located at the right end of the snap-fastener elastic band. A second hook-and-loop fastener is located at the left end of the snap-fastener elastic band, and the second hook-and-loop fastener is also a long rectangular strip. The first hook-and-loop fastener is shorter than the second hook-and-loop fastener. Although this allows for adjustment of tightness, repeated pasting of the hook and loop sides of the fastener can cause dust, hair, or dander to become embedded in the fiber gaps, reducing the contact area between the hook and loop and decreasing adhesion. Long-term sweat penetration or ultraviolet radiation may cause the polyester fibers of the fastener to harden, and the loops to straighten and deform, further reducing adhesion. During outdoor sports, sand, mud, and other particles may directly contaminate the surface of the fastener, accelerating its failure. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: An elastic ankle support device for preventing training injuries includes a rearfoot support base, which is a three-dimensional box shape adapted to the heel. A heel-limiting groove is formed on the inner wall surface of one end of the rearfoot support base. A rear ankle support assembly is fixedly installed between the two sides of the rearfoot support base. The rear ankle support assembly includes an Achilles tendon support band, a sponge pad, and a calf support arc plate. The outer walls of the Achilles tendon support band are fixedly installed on both sides of the inner walls of the rearfoot support base. The sponge pad is sewn onto the inner wall surface of the sponge pad. The bottom end of the calf support arc plate is symmetrically fixedly installed on both sides of the outer walls of the Achilles tendon support band. A rubber band for the instep is movably installed at the other end of the rearfoot support base.

[0005] As an improvement to the above technical solution, an arch support pad is fixedly installed on one side of the upper surface of the hindfoot support, and several sets of positioning grooves are opened on the other side of the upper surface of the hindfoot support. One end of the foot rubber band is fixedly installed to the side wall of the hindfoot support, and several sets of inserts are fixedly installed on the other end of the foot rubber band. The inserts can be tightly and movably inserted into the positioning groove.

[0006] As an improvement to the above technical solution, a fixing post is fixedly installed at the bottom end of the calf support arc plate, and the fixing post is inserted and fixedly installed with the side wall of the Achilles tendon support band. An elastic band is cross-fixed between the two sets of calf support arc plates.

[0007] As an improvement to the above technical solution, fixing nails are fixedly installed on both sides of the bottom end of the Achilles tendon support band.

[0008] As an improvement to the above technical solution, a cotton pad is provided on the inner wall of the calf support arc plate.

[0009] The beneficial effects of this utility model are: 1. This utility model reduces the inversion or eversion angle of the ankle joint by physically restraining the heel limiting groove, thereby reducing the risk of ligament tearing. The Achilles tendon support band of the posterior ankle support component is made of elastic nylon and is fixed to the inner walls of both sides of the posterior foot support seat by rivets. The Achilles tendon support band needs to achieve longitudinal stretching restriction during exercise to prevent excessive stretching of the Achilles tendon and inhibit lateral swing, thereby avoiding friction between the Achilles tendon and surrounding tissues. The calf support arc plate disperses the vertical impact force to the calf muscles to reduce talus damage. The material is made of nylon and spandex blend, which is not easy to loosen after long-term use. The antibacterial sponge pad inhibits the growth of Staphylococcus aureus and Escherichia coli.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0013] Please see Figure 1-4 This utility model provides a technical solution: An elastic ankle support device for preventing training injuries includes a rearfoot support seat 1, which is a three-dimensional box shape adapted to the heel. A heel limiting groove 11 is formed on the inner wall surface of one end of the rearfoot support seat 1. A rear ankle support component 2 is fixedly installed between the two sides of the rearfoot support seat 1. The rear ankle support component 2 includes an Achilles tendon support band 21, a sponge pad 22, and a calf support arc plate 23. The outer walls of the Achilles tendon support band 21 are fixedly installed on both sides of the inner walls of the rearfoot support seat 1. The sponge pad 22 is sewn onto the inner wall surface of the sponge pad 22. The bottom end of the calf support arc plate 23 is symmetrically fixedly installed on both sides of the outer walls of the Achilles tendon support band 21. A foot rubber band 3 is movably installed at the other end of the rearfoot support seat 1.

[0014] In this embodiment, the rearfoot support seat 1 is a three-dimensional box-shaped structure, ergonomically designed to fit the contour of the heel. An internal heel limiting groove 11 is provided, 1.5cm deep and matching the width of the heel to restrict heel displacement. The outer wall is made of high-strength polycarbonate (PC), providing strong impact resistance. The inner wall is covered with breathable mesh fabric and a 2mm thick silicone pad. The Achilles tendon support band 21 of the rear ankle support component 2 is an elastic nylon band, fixed at both ends to the inner walls of the rearfoot support seat 1 by rivets. The outer layer is a nylon-spandex blend, and the inner... The layered sewn sponge pad 22 is made of 8mm thick slow-rebound memory foam, with an antibacterial polyester fabric covering the surface to prevent bacteria growth from sweat. It uses double-thread chain stitching to ensure a firm connection with the Achilles tendon support band 21. The calf support arc plate 23 is symmetrically fixed to both sides of the outer wall of the Achilles tendon support band 21, with a curvature radius matching the back of the calf. It is made of glass fiber reinforced plastic (GFRP). The instep rubber band 3 is made of natural rubber. One end is glued to the side wall of the rear foot support seat 1 through an adhesive strip, and the other end is movably inserted into the rear foot support seat 1.

[0015] Beneficial effects: The heel limiting groove 11 physically restricts the inversion or eversion angle of the ankle joint, reducing the risk of ligament tearing. The Achilles tendon support band 21 of the posterior ankle support component 2 is an elastic nylon band, which is fixed to the inner walls of both sides of the posterior foot support seat 1 by rivets. The Achilles tendon support band 21 needs to achieve longitudinal stretching restriction during exercise to prevent excessive stretching of the Achilles tendon and inhibition of lateral swing, and avoid friction between the Achilles tendon and surrounding tissues. The calf support arc plate 23 disperses the vertical impact force to the calf muscles to reduce talus damage. The material is a nylon-spandex blend, which is not easy to loosen after long-term use. The antibacterial sponge pad 22 inhibits the growth of Staphylococcus aureus and Escherichia coli.

[0016] Instructions for use: Align your heel with the heel limiting groove 11 of the heel support seat 1, ensuring that the heel is fully embedded without any gaps. Tighten the Achilles tendon support band 21 so that the sponge pad 22 fits the Achilles tendon but is not too tight. Wrap the instep rubber band 3 around the instep and adjust the length using the instep rubber band 3 to ensure that the protective gear is wrinkle-free and securely fixed.

[0017] Specifically, an arch support 12 is fixedly installed on one side of the upper surface of the rear foot support 1, and several sets of positioning grooves 13 are opened on the other side of the upper surface of the rear foot support 1. One end of the foot rubber band 3 is fixedly installed to the side wall of the rear foot support 1, and several sets of inserts 31 are fixedly installed on the other end of the foot rubber band 3. The inserts 31 can be tightly and movably inserted into the inside of the positioning grooves 13.

[0018] In this embodiment, the arch support 12 is located on the inner side of the upper surface of the hindfoot support 1, conforming to the natural curve of the arch, distributing the pressure of the sole to the heel and forefoot, and reducing fatigue damage caused by single-point force. The positioning grooves 13 are opened on the outer side of the upper surface of the hindfoot support 1, forming a transverse U-shaped groove, with a total of 4 sets. The insert 31 is a TPE elastic post with a diameter of 6mm and a length of 7mm, which can be tightly inserted into the positioning grooves 13 to achieve stepless fixation of the instep rubber band 3. By adjusting the position of the insert 31 inserted into different positioning grooves 13, the fixing angle range of the instep rubber band 3 can be changed by ±15°, thereby adjusting the dorsiflexion or plantarflexion limitation range of the ankle joint. The positioning grooves 13 are made of alloy plastic, and the insert 31 is made of thermoplastic elastomer.

[0019] Specifically, a fixing post 231 is fixedly installed at the bottom of the calf support arc plate 23. The fixing post 231 is inserted and fixedly installed into the side wall of the Achilles tendon support band 21. An elastic band 232 is cross-fixed between the two sets of calf support arc plates 23.

[0020] In this embodiment, the calf support arc plate 23 adopts a double arc plate structure, which conforms to the natural contraction trajectory of the calf muscle group. When walking or running, the arc deformation disperses the muscle vibration energy and reduces muscle fatigue. The two sets of calf support arc plates 23 are cross-connected by elastic bands 232 to form an "X"-shaped dynamic pressure system. The elastic bands 232 are made of silicone coated polyester fiber. The fixing post 231 adopts a double frustum shape with a thicker top and a thinner bottom, which forms an interference fit with the insertion hole of the Achilles tendon support band 21.

[0021] Specifically, the bottom two sides of the Achilles tendon support band 21 are fixedly installed with fixing nails 211.

[0022] In this embodiment, the fixing nail 211 serves as a connector of the Achilles tendon support band 21 protective body. Through rigid fixation, the mechanical force of the support band is accurately transmitted to the target area, forming a stable "point-line-surface" system. The fixing nail 211 adopts a frustum-shaped cone shape, with a hemispherical nail head and a chamfered transition to avoid piercing the support band material and reduce friction with the skin.

[0023] Specifically, the inner wall of the calf support arc plate 23 is padded with cotton.

[0024] In this embodiment, a hot-press molding process is used to form a curved surface on the cotton pad that matches the contour of the calf, and the actual contact area with the skin is measured to reduce the displacement of the cotton layer during exercise.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
