Description

Technical Field

[0001] This utility model relates to the field of footwear, specifically to an anti-friction ankle protection structure for footwear. Background Technology

[0002] Ankle protection structures are specifically designed to protect the ankles of everyday footwear such as leather shoes and casual shoes. They are mainly used to optimize the protective performance of the area where the shoe upper contacts the ankle, solve the discomfort caused by the interaction between the ankle and the shoe body when wearing these types of shoes, and improve the overall comfort and safety of wearing them.

[0003] Traditional leather shoes or casual shoes have significant shortcomings in ankle protection design. On the one hand, the inner side of the upper that contacts the ankle is often made of a single material, lacking a dedicated breathable structure. This leads to stuffiness and heat in the ankle contact area due to poor ventilation. Furthermore, they lack a design that can effectively cushion, reduce friction, and distribute pressure, making the ankle prone to discomfort due to excessive local pressure or friction during wear. On the other hand, existing ankle protection components are mostly fixed to the upper, making them difficult to detach and replace. They cannot be replaced with different sizes of protection components according to different users' ankle circumference or actual usage needs, failing to meet personalized adaptation requirements. Moreover, during activities such as walking, these fixed protection components are prone to displacement or dislocation, failing to provide continuous and stable ankle protection. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a shoe body anti-friction ankle protection structure. The double-ring silicone sleeve is made of memory foam and liquid silicone through hot melt adhesive, which improves breathability and reduces friction. It solves the technical problem that the ankle contact area is prone to stuffiness due to poor ventilation, which makes the ankle prone to discomfort due to excessive local pressure or excessive friction.

[0005] The objective of this utility model is achieved through the following means:

[0006] An anti-abrasion ankle protection structure for a shoe includes a shoe body, which comprises an upper and a sole. The upper is located around the upper surface of the sole. A double-ring silicone sleeve is added to the inner side of the upper. The double-ring silicone sleeve is composed of memory foam and liquid silicone. Hot melt adhesive is added between the memory foam and the liquid silicone. The surface of the liquid silicone has a microporous breathable texture. An elastic slot is formed at the center of the back of the memory foam. A nylon slide rail is slidably connected to the inner cavity of the elastic slot. The nylon slide rail is embedded in the inner side of the upper. Elastic clips are installed on the inner ends of the upper and lower surfaces of the nylon slide rail. A slot is formed at the top and bottom of the inner cavity of the elastic slot. The elastic clips are engaged with the slots. Both the nylon slide rail and the elastic slot are T-shaped. A gradient cushioning layer is installed at the heel of the upper. The gradient cushioning layer includes a 3D printed mesh cushioning layer.

[0007] The double-ring silicone sleeve is made of memory foam and liquid silicone through hot melt adhesive. The liquid silicone is soft and can closely conform to the skin of the ankle, while the memory foam has good elastic cushioning performance. The combination of the two can effectively distribute the local pressure between the ankle and the shoe upper, reducing the friction between the shoe upper and the ankle. At the same time, the gradient cushioning layer in the heel area of ​​the shoe upper includes a 3D printed mesh cushioning layer, which can specifically absorb the impact on the heel and Achilles tendon area during walking, further reducing the risk of ankle wear and discomfort.

[0008] The surface of the liquid silicone has microporous breathable textures, which can promote air circulation between the ankle skin and the double-ring silicone sleeve, avoiding stuffiness and dampness caused by poor air circulation during long-term wear, and significantly improving the wearing comfort of the ankle area.

[0009] The nylon slide rail and elastic slot adopt a T-shaped design, which can effectively prevent the two from shifting or falling off when sliding together, ensuring assembly stability. The locking connection between the elastic head and the slot can firmly fix the double-ring silicone sleeve to the inside of the shoe upper, preventing the double-ring silicone sleeve from falling off during walking or sports. When it is necessary to clean or replace the double-ring silicone sleeve, simply apply external force to disengage the elastic head from the slot, and slide it along the nylon slide rail to remove it. The operation is convenient and efficient.

[0010] The double-ring silicone sleeve features a detachable design via nylon slide rails and elastic slots. Users can replace the double-ring silicone sleeve with different sizes according to their own ankle circumference, ankle bone shape, etc., ensuring that different people can get a suitable fit when wearing it, achieving personalized ankle protection and improving the adaptability of the protective structure.

[0011] Furthermore, the surface of the liquid silicone is uniformly provided with air-permeable channels, and the air-permeable channels are spiral in shape.

[0012] First, the uniform arrangement of spiral-shaped breathable channels significantly improves the breathability of the liquid silicone surface, effectively solving the risk of moisture and corrosion on the liquid silicone surface caused by gas accumulation, and ensuring the stability of the physical and chemical properties of the liquid silicone. Second, compared with straight channels, the spiral structure can extend the flow path with the same surface area, further improving the thoroughness of gas discharge and reducing residue. The spiral-shaped breathable channels utilize the compression deformation during ankle movement, such as when the ankle bends while walking, to create a "pumping effect." When compressed, air in the channel is discharged from the micropores, and when relaxed, external air is replenished along the spiral channel, actively accelerating air circulation.

[0013] Furthermore, the inner side of the nylon slide rail is provided with an elastic compensation piece, which is a three-layer stacked design, and micro rivets connect the nylon slide rail and the elastic compensation piece.

[0014] The three-layer composite design significantly enhances the elastic recovery capability and service life of the elastic compensation plate compared to a single-layer structure. This avoids permanent damage caused by excessive single deformation and extends the effective cycle of the compensation function. The micro-rivet connection method ensures the firmness of the connection between the nylon slide rail and the elastic compensation plate, preventing slide rail guide failure caused by the elastic compensation plate detaching and ensuring the stability of the device operation. The gap compensation function of the elastic compensation plate reduces frictional loss between the sliding parts and the nylon slide rail, improves the accuracy of slide rail guidance, and avoids wobbling of the sliding parts caused by excessive gap.

[0015] Furthermore, an elastic interlayer is added to the bonding surface between the memory foam and the liquid silicone. The elastic interlayer has an overall ring design, and V-shaped elastic folds are evenly distributed on the surface of the elastic interlayer along the circumference.

[0016] The annular elastic interlayer fills the tiny gaps between the memory foam and liquid silicone bonding surfaces, improving the tightness of the bond and avoiding problems such as decreased cushioning performance and sealing failure caused by gaps. The V-shaped elastic pleats expand the elastic deformation range of the interlayer, enabling it to adapt to different degrees of pressure changes and displacements, enhancing the overall structure's cushioning and shock absorption effect, and reducing damage to the memory foam and liquid silicone from external pressure. In addition, the elastic resilience of the interlayer reduces the risk of permanent deformation of the memory foam and liquid silicone due to long-term bonding pressure, extending their service life and ensuring the overall stability of the device's function.

[0017] Furthermore, the upper and lower surfaces of the nylon slide rail are provided with guide positioning grooves, and the top and bottom of the inner cavity of the elastic slot are provided with guide positioning blocks, which are slidably connected to the guide positioning grooves.

[0018] The symmetrical design of the guide positioning groove and guide positioning block ensures uniform force distribution during the sliding of the nylon slide rail, avoiding structural imbalance caused by unilateral positioning and improving the stability of the overall mating structure. The sliding connection method ensures smooth relative movement between the two, without adding extra frictional resistance due to the positioning structure, thus guaranteeing the efficient realization of the slide rail's guiding function. This positioning structure significantly improves the accuracy of the relative sliding between the nylon slide rail and the elastic slot, preventing component jamming and collision damage caused by misalignment, reducing the risk of device failure, and extending the service life of both.

[0019] Furthermore, the grid density of the 3D printed mesh buffer layer in the gradient buffer layer decreases from the inside to the outside, and micro hexagonal honeycomb units are embedded in the high-density area of ​​the inner grid of the 3D printed mesh buffer layer.

[0020] The gradient density decreasing design enables the gradient buffer layer to achieve hierarchical buffering. Compared with a single-density grid layer, it can more efficiently adapt to external forces of different magnitudes, improve buffering efficiency, and avoid buffer failure caused by force concentration. The micro hexagonal honeycomb cells have excellent structural stability and load-bearing capacity. Their embedding enhances the strength of the inner grid layer without significantly increasing the overall weight of the gradient buffer layer, achieving a balance between lightweight and high strength. The combination of layered buffering and the supporting role of honeycomb cells can effectively reduce the impact of external forces on the components protected by the gradient buffer layer, reduce the risk of component damage, and extend the overall service life of the device.

[0021] The beneficial effects of this utility model are as follows: the double-ring silicone sleeve is made of memory foam and liquid silicone through hot melt adhesive. The microporous breathable texture on the surface of the liquid silicone can improve the breathability of the part of the ankle that contacts the sleeve. The combination of memory foam and liquid silicone can effectively cushion the ankle, reduce the friction between the ankle and the inner side of the shoe, and at the same time disperse the local pressure on the ankle, avoiding ankle discomfort caused by excessive local pressure or excessive friction.

[0022] The elastic slot at the center of the back of the memory foam slides into the nylon slide rail embedded on the inner side of the shoe upper. Both the nylon slide rail and the elastic slot are T-shaped. With the locking connection of the elastic head and the slot, it can not only make the double-ring silicone sleeve easy to install and remove, but also ensure that the double-ring silicone sleeve is not easy to fall off during use, even when walking or exercising. At the same time, different sizes of double-ring silicone sleeves can be replaced according to different users' ankle circumference or usage needs to achieve personalized adaptation for different people.

[0023] The gradient cushioning layer with a 3D-printed mesh buffer layer installed in the heel area of ​​the shoe upper can absorb the impact on the Achilles tendon area during walking, reduce the repeated impact on the Achilles tendon area during walking, further protect the ankle area, reduce discomfort such as redness and swelling of the ankle after walking for a long time, and improve the overall wearing comfort.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The specific implementation of this anti-abrasion ankle protection structure for a shoe includes a shoe body part 1, which comprises an upper 2 and a sole 3. The upper 2 is located around the upper surface of the sole 3. A double-ring silicone sleeve 17 is added to the inner side of the upper 2. The double-ring silicone sleeve 17 is composed of memory foam 4 and liquid silicone 5. Hot melt adhesive is added between the memory foam 4 and the liquid silicone 5. The surface of the liquid silicone 5 has microporous breathable texture 6. An elastic slot 9 is provided at the center of the back of the memory foam 4. The inner cavity of the elastic slot 9 is slidably connected to a nylon slide rail 10. The nylon slide rail 10 is embedded in the inner side of the shoe upper 2. The upper and lower inner surfaces of the nylon slide rail 10 are equipped with elastic clips 11. The top and bottom inner ends of the inner cavity of the elastic slot 9 are provided with slots 14. The elastic clips 11 and slots 14 are connected by a snap-fit. Both the nylon slide rail 10 and the elastic slot 9 are T-shaped designs. The heel area of ​​the shoe upper 2 is equipped with a gradient cushioning layer 16, which includes a 3D printed mesh cushioning layer.

[0033] The shoe body 1 includes the upper 2 and the sole 3. The upper 2 is fixedly set on the upper surface of the sole 3 around the edges to form the main frame of the shoe body, providing basic support for the subsequent installation of the anti-friction ankle protection structure.

[0034] The double-ring silicone sleeve 17 is composed of memory foam 4 and liquid silicone 5. Hot melt adhesive is added between memory foam 4 and liquid silicone 5. The adhesive effect of hot melt adhesive makes memory foam 4 and liquid silicone 5 tightly bonded together. At the same time, microporous breathable texture 6 is opened on the surface of liquid silicone 5 to complete the pre-fabrication of double-ring silicone sleeve 17.

[0035] Since the nylon slide rail 10 is pre-embedded on the inner side of the shoe upper 2, and the memory foam 4 has an elastic slot 9 at the center of the back, and both the nylon slide rail 10 and the elastic slot 9 are T-shaped, the opening end of the elastic slot 9 is aligned with one end of the nylon slide rail 10, and the double-ring silicone sleeve 17 is pushed along the extension direction of the nylon slide rail 10, so that the nylon slide rail 10 slides into the inner cavity of the elastic slot 9; during the sliding process, the elastic locking heads 11 installed on the inner ends of the upper and lower surfaces of the nylon slide rail 10 will gradually approach the slots 14 opened at the top and bottom of the inner cavity of the elastic slot 9 as the nylon slide rail 10 slides. When the nylon slide rail 10 slides to the preset position, the elastic locking heads 11 and slots 14 are precisely aligned and locked together, thereby stably fixing the double-ring silicone sleeve 17 to the inner side of the shoe upper 2;

[0036] The gradient buffer layer 16, which includes a 3D-printed mesh buffer layer, is installed on the heel of the shoe upper 2, thus completing the assembly of the anti-abrasion ankle protection structure of the entire shoe body. In actual wear and use, the double-ring silicone sleeve 17 directly fits the ankle skin, and the gradient buffer layer 16 corresponds to the heel and Achilles tendon area, continuously playing an anti-abrasion and buffer protection role.

[0037] The double-ring silicone sleeve 17 is made of memory foam 4 and liquid silicone 5 through hot melt adhesive. Liquid silicone 5 is soft and can closely conform to the skin of the ankle, while memory foam 4 has good elastic cushioning performance. The combination of the two can effectively disperse the local pressure between the ankle and the shoe upper 2, and reduce the friction of the shoe upper 2 on the ankle. At the same time, the gradient cushioning layer 16 in the heel area of ​​the shoe upper 2 includes a 3D printed mesh cushioning layer, which can specifically absorb the impact on the heel and Achilles tendon area during walking, further reducing the risk of ankle wear and discomfort.

[0038] The surface of the liquid silicone 5 has microporous breathable texture 6, which can promote air circulation between the ankle skin and the double-ring silicone sleeve 17, avoiding stuffiness and dampness caused by poor air circulation during long-term wear, and significantly improving the wearing comfort of the ankle area.

[0039] The nylon slide rail 10 and the elastic slot 9 adopt a T-shaped design, which can effectively prevent the two from shifting or falling off when sliding together, ensuring assembly stability. The locking connection between the elastic clip 11 and the slot 14 can firmly fix the double-ring silicone sleeve 17 to the inner side of the shoe upper 2, preventing the double-ring silicone sleeve 17 from falling off during walking or exercise. When it is necessary to clean or replace the double-ring silicone sleeve 17, simply apply external force to make the elastic clip 11 disengage from the slot 14, and slide it along the nylon slide rail 10 to remove it. The operation is convenient and efficient.

[0040] The double-ring silicone sleeve 17 is designed to be detachable through the nylon slide rail 10 and the elastic slot 9. Users can replace the double-ring silicone sleeve 17 with different sizes according to their own ankle circumference, ankle bone shape and other conditions, to ensure that different people can get a suitable fit when wearing it, achieve personalized ankle protection and improve the adaptability of the protective structure.

[0041] like Figure 3 and Figure 4 As shown, the surface of the liquid silicone 5 is uniformly provided with air-permeable guide grooves 7, and the air-permeable guide grooves 7 are spiral in shape.

[0042] The liquid silicone 5 comes into direct contact with the skin of the foot. When gas is generated inside the shoe body 1, the evenly distributed spiral-shaped breathable channels 7 on the surface of the liquid silicone 5 come into play: the gas can enter the channels 7. Because the breathable channels 7 are spiral in shape, their channel paths are continuous and directional, which can guide the gas or trace amounts of liquid to flow in an orderly manner along the spiral trajectory, avoiding local accumulation on the surface of the liquid silicone 5; at the same time, the spiral structure can keep the flow resistance in the channels stable, without significant obstruction due to path turns, ensuring that the gas is continuously discharged outward or guided to a designated area; firstly, the spiral breathable... The uniform opening of the air guide groove 7 can significantly improve the air permeability of the liquid silicone 5 surface, effectively solve the risk of moisture and corrosion on the surface of liquid silicone 5 caused by gas accumulation, and ensure the stability of the physical and chemical properties of liquid silicone 5. Secondly, compared with the straight channel, the spiral structure can extend the guide path with the same surface area, further improving the thoroughness of gas discharge and reducing residue. The spiral air permeable guide groove 7 utilizes the compression deformation during ankle movement, such as when the ankle bends during walking, to form a "pumping effect". When squeezed, the air in the groove is discharged from the micropores, and when relaxed, the external air is replenished along the spiral groove, actively accelerating the air circulation.

[0043] like Figure 4 and Figure 5 As shown, an elastic compensation piece 13 is added to the inner side of the nylon slide rail 10. The elastic compensation piece 13 has a three-layer stacked design, and micro rivets connect the nylon slide rail 10 and the elastic compensation piece 13.

[0044] The nylon slide rail 10 is mainly used in the device to guide the sliding of components. Its inner surface corresponds to the contact area of ​​the sliding component. When the sliding component slides along the inner side of the nylon slide rail 10, if the gap between the sliding component and the inner wall of the nylon slide rail 10 increases due to long-term wear, assembly errors, or temperature changes, the three-layer composite elastic compensation plate 13 added to the inner surface of the nylon slide rail 10 will fill the gap through its own elastic deformation. The three-layer composite structure of the elastic compensation plate 13 provides sufficient elastic deformation space. The outer thin plate deforms first, and the inner thin plate further assists in compensation, ensuring that the gap is stably filled and maintaining close contact between the sliding component and the nylon slide rail 10. At the same time, the micro rivets connecting the nylon slide rail 10 and the elastic compensation plate 13... The elastic compensation piece 13 can be firmly fixed to the inner side of the nylon slide rail 10, preventing displacement or detachment of the elastic compensation piece 13 during long-term deformation or sliding friction. The three-layer composite design makes the elastic recovery capability and service life of the elastic compensation piece 13 significantly better than that of a single-layer structure, avoiding permanent damage caused by excessive single deformation and extending the effective cycle of the compensation function. The connection method of micro rivets ensures the firmness of the connection between the nylon slide rail 10 and the elastic compensation piece 13, preventing slide rail guide failure caused by the detachment of the elastic compensation piece 13 and ensuring the stability of the device operation. The gap compensation function of the elastic compensation piece 13 can reduce the frictional loss between the sliding parts and the nylon slide rail 10, improve the accuracy of slide rail guidance, and avoid the shaking of the sliding parts caused by excessive gap.

[0045] like Figure 4 As shown, an elastic interlayer 8 is added to the bonding surface of the memory foam 4 and the liquid silicone 5. The elastic interlayer 8 is a ring-shaped design, and V-shaped elastic folds are evenly distributed on the surface of the elastic interlayer 8 along the circumference.

[0046] After assembly, the memory foam 4 and liquid silicone 5 need to maintain a stable fit to achieve functions such as cushioning and sealing. When the two are subjected to external pressure or undergo slight relative displacement during device operation, the annular elastic interlayer 8 added to the bonding surface will undergo elastic deformation with changes in pressure or displacement. The annular structure ensures that the deformation is evenly distributed in the circumferential direction, avoiding uneven stress on the bonding surface caused by excessive local deformation. At the same time, the V-shaped elastic pleats evenly distributed in the circumferential direction on the surface of the elastic interlayer 8 can further enhance the deformation capacity. When compressed, the V-shaped pleats are compressed and deformed, absorbing pressure energy. When the pressure is released or the displacement is restored, the V-shaped elastic pleats quickly rebound, causing the elastic interlayer 8 to return to its initial shape, thereby maintaining the memory foam. The tight fit between the memory foam 4 and the liquid silicone 5 prevents gaps from forming on the bonding surface. The annular elastic interlayer 8 fills the tiny gaps between the memory foam 4 and the liquid silicone 5, improving the tightness of the fit and avoiding problems such as decreased cushioning performance and sealing failure caused by gaps. The V-shaped elastic pleats expand the elastic deformation range of the elastic interlayer 8, enabling it to adapt to different degrees of pressure changes and displacements, enhancing the overall cushioning and shock absorption effect of the structure, and reducing damage to the memory foam 4 and liquid silicone 5 from external pressure. In addition, the elastic resilience of the elastic interlayer 8 can reduce the risk of permanent deformation of the memory foam 4 and liquid silicone 5 due to long-term bonding pressure, extend their service life, and ensure the overall stability of the device.

[0047] like Figure 5 and Figure 6 As shown, the upper and lower surfaces of the nylon slide rail 10 are provided with guide positioning grooves 12, and the top and bottom of the inner cavity of the elastic slot 9 are provided with guide positioning blocks 15. The guide positioning blocks 15 and the guide positioning grooves 12 are slidably connected.

[0048] When assembling the nylon slide rail 10 with the elastic slot 9, the guide positioning blocks 15 at the top and bottom outer ends of the inner cavity of the elastic slot 9 must first be aligned with the guide positioning grooves 12 at the outer ends of the upper and lower surfaces of the nylon slide rail 10, so that the guide positioning blocks 15 are embedded in the guide positioning grooves 12. During the operation of the device, when the nylon slide rail 10 and the elastic slot 9 slide relative to each other, the guide positioning blocks 15 will slide synchronously along the groove direction of the guide positioning groove 12. Through the sliding cooperation between the two, the sliding trajectory of the nylon slide rail 10 is restricted, preventing it from shifting vertically or horizontally during the sliding process, ensuring that the nylon slide rail 10 always remains within the groove. The elastic slot 9 slides stably in a specified direction; the symmetrical design of the guide positioning groove 12 and the guide positioning block 15 ensures that the nylon slide rail 10 is subjected to uniform force when sliding, avoiding structural force imbalance caused by unilateral positioning and improving the stability of the overall mating structure; the sliding connection method ensures the smoothness of the relative movement between the two, and will not increase the additional frictional resistance due to the positioning structure, ensuring the efficient realization of the slide rail guiding function; this positioning structure can significantly improve the accuracy of the relative sliding between the nylon slide rail 10 and the elastic slot 9, prevent component jamming and collision damage caused by offset, reduce the risk of device failure, and extend the service life of both.

[0049] In the gradient buffer layer 16, the mesh density of the 3D printed mesh buffer layer decreases from the inside to the outside, and micro hexagonal honeycomb units are embedded in the high-density area of ​​the inner mesh of the 3D printed mesh buffer layer.

[0050] When the gradient buffer layer 16 is subjected to external impact or pressure, its internal 3D-printed mesh buffer layer plays a buffering role: Since the mesh density decreases from the inside to the outside, the external force first acts on the outer mesh layer with lower density. The outer mesh layer initially disperses and absorbs the force energy through the deformation of its mesh structure. The remaining force energy continues to be transmitted inward, where the inner mesh layer, with its denser mesh structure, further absorbs and buffers the force energy, achieving layered transmission and consumption of force energy. Simultaneously, the micro-hexagonal honeycomb units embedded in the high-density areas of the inner mesh layer enhance its structural strength, preventing excessive deformation or breakage due to excessive force during energy absorption, thus ensuring the gradient buffer layer's stability. The structural integrity of the buffer layer 16 ensures its continuous buffering function. The gradient design of decreasing grid density enables the gradient buffer layer 16 to achieve hierarchical buffering, which can more efficiently adapt to external forces of different magnitudes compared to a single-density grid layer, improving buffering efficiency and avoiding buffer failure caused by force concentration. The micro hexagonal honeycomb unit has excellent structural stability and load-bearing capacity. Its embedding enhances the strength of the inner grid layer without significantly increasing the overall weight of the gradient buffer layer 16, achieving a balance between lightweight and high strength. The combination of layered buffering and the supporting role of the honeycomb unit can effectively reduce the impact of external forces on the components protected by the gradient buffer layer 16, reduce the risk of component damage, and extend the overall service life of the device.

[0051] This embodiment of a shoe body provides an anti-friction ankle protection structure: a double-ring silicone sleeve 17 directly adheres to the ankle skin, liquid silicone 5 is soft and conforms to the skin, and memory foam 4 provides elastic cushioning. The two work together to disperse local pressure between the ankle and the shoe upper 2, reducing friction; the elastic interlayer 8 of the contact surface undergoes elastic deformation with ankle movement, and the V-shaped elastic pleats compress and rebound, maintaining a tight fit between the memory foam 4 and the liquid silicone 5, avoiding gaps; the microporous breathable texture 6 on the surface of the liquid silicone 5 promotes air circulation, and the spiral breathable channel 7 guides the orderly flow of gas, and forms a "pump effect" when the ankle bends, accelerating air circulation and avoiding stuffiness and dampness;

[0052] When impacted, the gradient cushioning layer 16 at the heel of the shoe upper 2 initially disperses and absorbs force energy through the outer low-density mesh layer, while the inner high-density mesh layer further cushions the impact. The micro hexagonal honeycomb units enhance the structural strength of the inner side, reducing the impact on the heel and Achilles tendon area. The elastic compensation piece 13 on the inner side of the nylon slide rail 10 fills the sliding gap caused by long-term use or temperature changes through the elastic deformation of the three-layer composite structure, maintaining the sliding stability of the double-ring silicone sleeve 17 and reducing friction loss. The cooperation between the guide positioning groove 12 and the guide positioning block 15 restricts the sliding trajectory of the nylon slide rail 10 and the elastic slot 9, preventing deviation and jamming.

[0053] When it is necessary to clean or replace the double-ring silicone sleeve 17, apply external force to disengage the elastic clip 11 from the slot 14, and slide it along the nylon slide rail 10 to remove the double-ring silicone sleeve 17. Users can replace the double-ring silicone sleeve 17 with different sizes according to their own ankle conditions to ensure fit and protection.
