Description

Technical Field

[0001] This utility model belongs to the field of shoe sole technology, and particularly relates to an embedded replaceable shock-absorbing and anti-slip device, outsole and shoe sole. Background Technology

[0002] As the core component in contact between the human body and the ground, shoe soles are widely used in outdoor sports equipment, industrial protective footwear, and special-operation equipment, providing users with grip, stability, and protection. In extreme environments such as mountaineering, trail running, and snow exploration, the anti-slip performance of shoe soles directly affects the safety and work efficiency of athletes. In these outdoor scenarios, shoe soles must simultaneously cope with various complex terrains such as ice and snow, slippery rocks, and muddy mountain paths, which places higher demands on anti-slip technology.

[0003] While existing climbing shoes enhance grip on icy and snowy terrain through designs such as embedded steel spikes and serrated patterns, they still have technical shortcomings. Although fixed steel spikes can temporarily embed themselves into the ice, they produce rigid impacts when in contact with hard surfaces (such as exposed rocks and frozen soil), making them unsuitable for various terrain features. This not only leads to strong tremors while walking but also causes foot fatigue with prolonged use. Furthermore, when some steel spike components are damaged, replacement is complicated because the spikes are fixed to the sole. In extreme environments where energy needs to be conserved to cope with the challenges, quick disassembly and adjustment are not possible, resulting in a poor user experience.

[0004] As in the prior art, the shoe with anti-slip accessories is also disclosed in the publication number TW200608911A. However, it requires manual adjustment of the sole's extension and retraction to control the friction with the ground, which is extremely inconvenient. Therefore, it is particularly important to design a sole with an embedded replaceable shock-absorbing and anti-slip device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the aforementioned problems in the prior art, this utility model provides an embedded, replaceable shock-absorbing and anti-slip device that adapts to shock absorption through elastic deformation, facilitating human movement.

[0007] This utility model also provides a rubber outsole, which can be equipped with an embedded replaceable shock-absorbing and anti-slip device to cope with different sports scenarios, making it easy to replace and disassemble, and improving the anti-slip and shock-absorbing capabilities.

[0008] This utility model also provides a shoe sole, which can adaptively absorb shock in response to uneven conditions in different sports scenarios by using a rubber outsole with an embedded replaceable shock-absorbing and anti-slip device. It is easy to replace and disassemble, improves anti-slip and shock-absorbing capabilities, and is easy to process.

[0009] This invention also provides an application of an embedded replaceable shock-absorbing and anti-slip device, which provides additional grip to the main body of the application and prevents slippage.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0012] An embedded, replaceable shock-absorbing and anti-slip device includes an embedded pin assembly for shock absorption and anti-slip purposes, the embedded pin assembly comprising:

[0013] The device includes a guide member and a fixed base that are movable up and down, as well as an anti-slip part located between the guide member and the fixed base. The guide member is used to guide and engage the shock-absorbing and anti-slip device, the fixed base is used to prevent the shock-absorbing and anti-slip device from slipping out, and the anti-slip part is used to prevent slipping and gripping the ground when in contact with the ground.

[0014] Furthermore, the guide includes a first contact portion and a first connecting portion disposed at the bottom of the first contact portion, wherein a first receiving groove is formed in the first connecting portion;

The bottom of the second receiving groove is coaxially provided with a positioning groove, and the bottom surface of the seat body is provided with a through hole.

[0016] The first connecting part is movably disposed in the second receiving groove, and the through hole and the positioning groove are axially connected, so that the fixed base forms a structure that is connected from top to bottom, thereby improving the stability of anti-slip grip.

[0017] Furthermore, the outer wall of the first connecting part is provided with an external thread, and the inner wall of the second receiving groove is provided with an internal thread that mates with the thread on the outer wall of the first connecting part, which facilitates installation and connection.

[0018] Furthermore, the diameter of the second receiving groove is larger than that of the positioning groove, and the diameter of the positioning groove is larger than that of the through hole, thereby improving structural stability.

[0019] Furthermore, the anti-slip part includes an anti-slip pin, and the outer wall of the anti-slip pin is provided with a limiting flange that is adapted to the positioning groove along the radial direction;

[0020] The anti-slip pin is fixedly embedded in the positioning groove, with one end penetrating through the through hole and the other end extending into the first receiving groove and abutting against the top wall of the first receiving groove to prevent loosening.

[0021] Furthermore, the anti-slip part includes an anti-slip pin, the outer wall of which extends radially and is provided with a limiting flange adapted to the positioning groove. The anti-slip part also includes a spring, one end of which is embedded in the first receiving groove, and the other end is sleeved on the anti-slip pin and abuts against the top surface of the limiting flange.

[0022] The anti-slip pin is embedded in the positioning groove, with one end penetrating through the through hole, and the other end is telescopically set in the second receiving groove through the spring, thereby improving the anti-slip force when in contact with the ground.

[0023] Furthermore, the first contact portion is hemispherical in shape, which facilitates quick guidance during installation.

[0024] Furthermore, the base is a polygonal frustum structure with equal upper and lower sides to prevent horizontal rotational movement.

[0025] Furthermore, a portion of the first connecting part is installed in the second receiving groove, and another portion is exposed outside the opening of the second receiving groove, forming an annular limiting groove together with the bottom surface of the first contact part and the top surface of the seat, which is used to prevent it from coming off vertically and improve stability.

[0026] Furthermore, the anti-slip part is made of any one of steel, plastic, or carbon fiber to improve its applicability and reliability.

[0027] As another aspect of this utility model, a rubber outsole is provided, wherein the rubber outsole includes an outsole body, the outsole body includes a first surface for contacting the ground and a second surface attached to the midsole of the shoe sole, and at least one embedded replaceable shock-absorbing and anti-slip device as described above is detachably provided on the first surface of the outsole body.

[0028] The first surface includes an anti-slip unit extending from the outsole body of the rubber outsole toward the ground to a first height H1, which is used to provide a first anti-slip force and improve the basic anti-slip capability.

[0029] At least one anti-slip unit includes an anti-slip block, which has a fitting groove for detachably installing an embedded stud assembly. When the embedded stud assembly is installed in the fitting groove, the embedded stud assembly extends from the outsole body of the rubber outsole toward the ground to a second height H2 to provide a second anti-slip force and provide stronger anti-slip capability.

[0030] Furthermore, the rubber outsole includes an outsole body, which includes a first surface for contacting the ground and a second surface attached to the midsole of the shoe sole. On the first surface of the outsole body, at least one embedded replaceable shock-absorbing and anti-slip device as described above is detachably provided.

[0031] The first surface includes an anti-slip unit extending from the outsole body of the rubber outsole toward the ground to a first height H1, which is used to provide a first anti-slip force and improve the basic anti-slip capability.

[0032] At least one anti-slip unit includes an anti-slip block, which has a fitting groove for detachably installing an embedded stud assembly. When the embedded stud assembly is installed in the fitting groove, the embedded stud assembly extends from the outsole body of the rubber outsole toward the ground to a height between a first height H1 and a second height H2, providing an adaptive second anti-slip force, providing stronger anti-slip capability while also having dynamic shock absorption capability.

[0033] Furthermore, during the walking process, when the rubber outsole contacts the ground, the spring of the embedded stud assembly adaptively deforms elastically to the changes in the center of gravity during walking, so as to provide a height between the first height H1 and the second height H2, thereby improving the dynamic shock absorption capability.

[0034] Furthermore, the fitting groove has a multi-layer structure, and a limiting block adapted to the limiting groove is provided between the upper and lower layers of the fitting groove. The limiting block divides the fitting groove into an upper groove and a lower groove, and the shapes of the upper and lower layers are adapted to the first connecting part and the base respectively, thereby improving the stability during assembly.

[0035] Furthermore, when the embedded pin assembly engages with the fitting groove, its first contact portion is guided into the upper groove, and the limiting block engages with the limiting groove to restrict the axial movement of the embedded pin assembly and prevent slippage.

[0036] Furthermore, when the embedded nail assembly engages with the fitting groove, its base engages with the lower groove, which is a polygonal groove adapted to the base, forming a geometric constraint on the nail assembly, improving stability, limiting the horizontal rotational movement of the nail assembly, and enhancing the anti-detachment effect.

[0037] Furthermore, the bottom wall of the fitting groove protrudes upward, forming a spherical protrusion on the top surface of the base body, which provides space to accommodate the embedded nail assembly. The depth of this space is related to the height of the embedded nail assembly, thereby improving shock absorption.

[0038] Furthermore, a prying groove is provided on the inner wall of any side of the fitting groove to facilitate disassembly.

[0039] Furthermore, it also includes an installation and removal auxiliary tool for installing and removing the embedded nail assembly. The installation and removal auxiliary tool includes a prying part and a holding part. The bottom of the holding part is provided with a positioning hole for assisting installation, which facilitates installation.

[0040] Furthermore, the anti-slip units are distributed in a fractal geometry on the forefoot and heel of the outsole body, respectively, to disperse foot pressure and improve comfort.

[0041] Furthermore, the bottom of the outsole body is also provided with several anti-slip patterns to enhance grip and improve the anti-slip effect.

[0042] Furthermore, the rubber outsole is mainly made of rare earth butadiene rubber and nitrile rubber to improve the tear strength, tensile strength and wear resistance of the rubber outsole.

[0043] As another aspect of this utility model, a shoe sole is provided, which further includes a midsole having a first surface for contacting the instep and a second surface for contacting the rubber outsole;

[0044] The second contact surface is made of rubber outsole according to any one of the above-mentioned features, which is used to improve the anti-slip force of the sole.

[0045] The second surface of the midsole has at least one groove that adapts to the protrusion to provide mounting space.

[0046] Furthermore, the groove is used to provide space to accommodate the protrusion, the depth of which is positively correlated with the height of the protrusion accommodating the embedded pin assembly, thereby improving the stability of the assembly and preventing slippage.

[0047] Furthermore, the outsole body and the midsole are bonded together using one of the following methods: adhesive bonding, hot melting, or stitching, which improves the durability and production efficiency of the shoes.

[0048] Furthermore, the embedded stud assembly is arranged in a fractal geometric pattern in the forefoot of the sole, with at least two embedded stud assemblies as the center, and the embedded stud assembly is arranged in a fractal geometric pattern in the heel of the sole, with at least one embedded stud assembly as the center, so that the force distribution on the sole is even.

[0049] Furthermore, the outsole body, midsole, and embedded stud assembly are processed in layers, which improves yield, reduces cost, and facilitates processing.

[0050] (III) Beneficial Effects

[0051] The beneficial effects of this invention are as follows: The embedded stud assembly can adaptively adjust according to ground conditions. When dealing with complex and diverse extreme outdoor terrains, such as exposed rocks, icy roads, slippery rocks, muddy mountain paths, or frozen ground, the springs in the embedded stud assembly will elastically deform according to the changes in the center of gravity during walking. Furthermore, the springs effectively absorb impact force and improve shock absorption performance through their cushioning effect. This significantly improves walking comfort, effectively reduces foot fatigue caused by prolonged walking, and the embedded stud assembly can respond quickly as the center of gravity of the foot shifts forward and backward, ensuring that the sole of the shoe maintains reliable friction with the ground at all times, effectively preventing slips and improving safety when walking on complex terrain.

[0052] When some embedded nail components are damaged, this invention allows for quick replacement and adjustment. In extreme environments, users can maintain the good performance of the sole without expending excessive physical effort on complex repairs, providing more reliable protection for users during outdoor adventures and special operations.

[0080] Example 1

[0081] Figure 1 This is a schematic diagram of an embedded replaceable shock-absorbing and anti-slip device according to an embodiment of the present utility model. Figure 1 As shown, the structure of the embedded replaceable shock-absorbing and anti-slip device according to the present invention will be described in detail.

[0082] The embedded replaceable shock-absorbing and anti-slip device according to an embodiment of the present invention includes an embedded nail assembly 1 for shock absorption and anti-slip, the embedded nail assembly 1 comprising:

[0083] The guide 11 and the fixed base 12 are movable up and down, and the anti-slip part 13 is provided between the guide 11 and the fixed base 12. The guide 11 is used to guide and engage the shock-absorbing and anti-slip device, the fixed base 12 is used to prevent the shock-absorbing and anti-slip device from slipping out, and the anti-slip part 13 is used to prevent slipping and gripping the ground when in contact with the ground.

[0084] Figure 2 This is an exploded sectional view of the embedded nail assembly according to an embodiment of the present invention, as shown below. Figure 2 As shown, the structure of the embedded nail assembly according to an embodiment of the present invention will be described in detail.

[0085] To improve the stability of anti-slip grip, the guide member 11 includes a first contact portion 111 and a first connecting portion 112 located at the bottom of the first contact portion 111. A first receiving groove 113 is provided in the first connecting portion 112. The fixed base 12 is located at the bottom of the guide member 11 and includes a seat body 121 and a second receiving groove 122 located inside the seat body 121. A positioning groove 123 is coaxially provided at the bottom of the second receiving groove 122. A through hole 124 is provided on the bottom surface of the seat body 121. The first connecting portion 112 is movably disposed in the second receiving groove 122. The through hole 124 and the positioning groove 123 are axially connected, so that the fixed base 12 forms a structure that is connected vertically.

[0086] Figure 3 An exploded view of the embedded nail assembly according to an embodiment of the present utility model is shown below. Figure 3 As shown, the connection method of the embedded nail assembly according to this utility model will be described in detail.

[0087] To improve stability, the outer wall of the first connecting part 112 is provided with an external thread, and the inner wall of the second receiving groove 122 is provided with an internal thread that mates with the thread on the outer wall of the first connecting part 112. The threaded connection is stable and convenient, and can be quickly replaced and disassembled, thus improving convenience.

[0088] Figure 4 This is a cross-sectional view of the fixing base of the embedded nail assembly according to an embodiment of the present utility model, as shown below. Figure 4 As shown, the structure of the seat according to an embodiment of the present invention will be described in detail.

[0089] In order to fit the anti-slip part 13, the diameter of the second receiving groove 122 is larger than that of the positioning groove 123, and the diameter of the positioning groove 123 is larger than that of the through hole 124. The positioning groove 123 is set to fit the anti-slip part 13 to improve its stability and prevent loosening.

[0090] Figure 3 This is an exploded view of the embedded nail assembly according to an embodiment of the present utility model. Figure 5 This is a combined cross-sectional view of the embedded nail assembly according to an embodiment of the present utility model, such as... Figure 3 and Figure 5 As shown, the combined structure of the embedded nail assembly according to an embodiment of the present invention will be described in detail.

[0091] To improve stability, the anti-slip part 13 includes an anti-slip pin 131. The outer wall of the anti-slip pin 131 extends radially and is provided with a limiting flange 133 that is adapted to the positioning groove 123. The anti-slip pin 131 is fixedly embedded in the positioning groove 123, with one end penetrating the through hole 124 and the other end extending into the first receiving groove 113 and abutting against the top wall of the first receiving groove 113. By providing a limiting flange 133 on the outer wall of the anti-slip pin 131 and adapting it to the positioning groove 123, the anti-slip pin 131 can be firmly embedded in the positioning groove 123, avoiding displacement or loosening due to external forces during use. This not only enhances the overall stability of the anti-slip part 13 but also effectively improves its service life.

[0092] Figure 1 This is a structural schematic diagram of the embedded nail assembly according to an embodiment of the present utility model, as shown below. Figure 1 As shown, the overall structure of the embedded nail assembly according to an embodiment of the present invention will be described in detail.

[0093] To facilitate rapid assembly and positioning of the device, the first contact part 111 is hemispherical in shape. The hemispherical arc shape not only provides guidance and facilitates locking and assembly, but also reduces frictional resistance during assembly and ensures precise alignment between components.

[0094] To prevent horizontal rotation and movement, the base 121 is a polygonal frustum structure with equal upper and lower sides. The geometric characteristics of the polygonal frustum can provide geometric constraints in the horizontal direction, effectively limiting the rotation or displacement of the component on the horizontal plane, thereby ensuring the reliability of the device in dynamic environments.

[0095] Figure 6 This is a cross-sectional view of the embedded nail assembly according to an embodiment of the present invention, as shown below. Figure 6 As shown, the overall structure of the embedded nail assembly according to an embodiment of the present invention will be described in detail.

[0096] To prevent slippage, a portion of the first connecting part 112 is installed in the second receiving groove 122, and another portion is exposed outside the opening of the second receiving groove 122. Together with the bottom surface of the first contact part 111 and the top surface of the seat 121, they form an annular limiting groove 114 to prevent vertical slippage. The limiting groove 114 forms a groove in the radial direction to limit its axial movement, prevent vibration slippage during movement, and improve stability.

[0097] To adapt to different scenario requirements, the anti-slip part 13 can be made of any one of steel, plastic, or carbon fiber, which can meet the needs of different application scenarios. Combining the advantages of various materials improves the applicability and reliability of the device and provides users with flexible selection space.

[0098] Example 2

[0099] For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus is on the structure that is different from Embodiment 1 of this utility model. The difference between Embodiment 2 and Embodiment 1 is the setting of adaptive shock absorption of the nail assembly 1.

[0100] Figure 7 This is an exploded sectional view of an embedded nail assembly according to another embodiment of the present invention. Figure 8 This is a combined cross-sectional view of the embedded nail assembly according to another embodiment of the present invention, such as... Figure 7 and Figure 8 As shown, the combined structure of the embedded nail assembly according to another embodiment of the present invention will be described in detail.

[0101] To adapt to various terrain features, the anti-slip part 13 includes an anti-slip pin 131. The outer wall of the anti-slip pin 131 extends radially and is provided with a limiting flange 133 that matches the positioning groove 123. The anti-slip part 13 also includes a spring 132. One end of the spring 132 is embedded in the first receiving groove 113, and the other end is sleeved on the anti-slip pin 131 and abuts against the top surface of the limiting flange 133. The anti-slip pin 131 is embedded in the positioning groove 123 and one end penetrates the through hole 124. The other end is telescopically disposed in the second receiving groove 122 through the spring 132. Through the elastic deformation of the spring 132, the anti-slip pin 131 achieves adaptive feedback to different terrain changes and the rise and fall of the foot's center of gravity.

[0102] [Rubber outsole according to an embodiment of this utility model]

[0103] Example 1

[0104] Figure 9 This is a schematic diagram of the structure of the rubber outsole according to an embodiment of the present utility model. Figure 10 This is a partial cross-sectional view of the rubber outsole according to an embodiment of the present invention, such as... Figure 9 and Figure 10 As shown, the overall structure of the rubber outsole according to an embodiment of the present invention will be described in detail.

[0105] As another aspect of this utility model, a rubber outsole is provided. The rubber outsole includes an outsole body 2, which includes a first surface for contacting the ground and a second surface attached to the midsole of the shoe. On the first surface of the outsole body 2, at least one embedded replaceable shock-absorbing and anti-slip device as described above is detachably provided. The device is provided on the rubber outsole to improve the anti-slip performance of the rubber outsole.

[0106] The first surface includes an anti-slip unit 21 extending from the outsole body 2 of the rubber outsole toward the ground to a first height H1, which is used to provide a first anti-slip force. When the foot contacts the ground, the anti-slip unit 21 can contact the ground first, increasing the contact area with the ground and closely conforming to the uneven structure of the ground, thereby increasing the friction of the first surface of the rubber outsole that contacts the ground and preventing slipping.

[0107] At least one anti-slip unit 21 includes an anti-slip block 211, which has a fitting groove 212 for detachably installing an embedded stud assembly 1. When the embedded stud assembly 1 is installed in the fitting groove 212, the stud assembly 1 extends from the outsole body 2 of the rubber outsole towards the ground to a second height H2 to provide a second anti-slip force. When the foot contacts the ground, the stud assembly 1 first contacts the ground to provide the second anti-slip force, increasing the contact depth with the ground. The stud assembly 1 can penetrate the surface layer of the ground (such as snow, mud, or ice) to directly contact the lower layer of the ground to provide a stronger anti-slip force. Then, the anti-slip unit 21 contacts the ground to provide the first anti-slip force, providing more contact area with the ground. This double anti-slip is suitable for contacting hard surfaces (such as exposed rocks or frozen soil) in some extreme environments, providing a reliable anti-slip effect.

[0108] Figure 11 This is a cross-sectional view of the fitting groove according to an embodiment of the present utility model, as shown below. Figure 11 As shown, the overall structure of the fitting groove according to an embodiment of the present utility model will be described in detail.

[0109] To improve the stability of the rubber outsole, the fitting groove 212 has a multi-layer structure. A limiting block 215 adapted to the limiting groove 114 is provided between the upper and lower layers of the fitting groove 212. The limiting block 215 divides the fitting groove 212 into an upper groove 2121 and a lower groove 2122, which are respectively adapted to the first connecting part 112 and the seat 121, providing double-layer fixed protection in both longitudinal and transverse directions. This effectively improves the stability during movement, prevents slippage, and allows the rubber outsole to maintain good grip under various ground conditions, such as wet, slippery, or oily conditions. This effectively prevents slippage and improves the safety and comfort of the user. At the same time, the nail assembly 1 can be quickly removed from the fitting groove 212 if it is damaged.

[0110] To improve axial stability, when the nail assembly 1 engages with the fitting groove 212, its first contact portion 111 is guided into the upper groove 2121. The limiting block 215 engages with the limiting groove 114 to restrict the axial movement of the nail assembly 1 and prevent slippage during movement.

[0111] To improve horizontal stability, when the nail assembly 1 engages with the fitting groove 212, its base 121 engages with the lower groove 2122. The lower groove 2122 is a polygonal groove that matches the base 121, forming a geometric constraint on the nail assembly 1 to limit the horizontal rotational movement of the nail assembly 1 and enhance the anti-loosening effect.

[0112] Figure 10 This is a partial cross-sectional view of the rubber outsole according to an embodiment of the present invention, such as... Figure 10As shown, the protrusion structure of the rubber outsole according to an embodiment of the present invention will be described in detail.

[0113] In order to provide space for the nail assembly 1, the bottom wall of the fitting groove 212 protrudes upward, forming a spherical protrusion 213 on the top surface of the base body 2, which provides space for accommodating the nail assembly 1, the depth of which is related to the height of the nail assembly 1.

[0114] Figure 12 This is a partial enlarged view of the rubber outsole according to an embodiment of the present invention, such as... Figure 12 As shown, the structure of the pry groove of the rubber outsole according to an embodiment of the present invention will be described in detail.

[0115] To facilitate disassembly and replacement, a prying groove 214 is provided on the inner wall of any side of the fitting groove 212, which is used for quick disassembly and replacement of the nail assembly 1. When the nail assembly 1 is damaged, it can be quickly removed and replaced through the prying groove 214, thus improving convenience.

Figure 13 As shown, the structure of the loading and unloading auxiliary tool according to an embodiment of the present utility model will be described in detail.

[0117] For ease of disassembly and replacement, an auxiliary tool 3 for installing and removing the embedded nail assembly 1 is also included. The auxiliary tool 3 includes a prying part 31 and a holding part 32. The bottom of the holding part 32 is provided with a positioning hole 33 for assisting installation.

[0118] Figure 9 This is a schematic diagram of the structure of the rubber outsole according to an embodiment of the present utility model, as shown below. Figure 9 As shown, the shock absorption and anti-slip effect of the rubber outsole according to the embodiments of the present invention will be described in detail.

[0119] To improve comfort and shock absorption, the anti-slip units 21 are arranged in a fractal geometric distribution on the forefoot and heel of the outsole body 2, respectively, to disperse the pressure on the sole and improve comfort. The fractal geometric distribution of the anti-slip units 21 can ensure that the pressure in each area of ​​the sole is evenly distributed, thereby reducing the situation of excessive local pressure and improving wearing comfort. At the same time, it can fully absorb and disperse the impact force when the foot contacts the ground, so that each anti-slip unit 21 can independently buffer the impact force, thereby reducing the vibration of the foot and providing a better shock absorption effect.

[0120] To enhance the anti-slip effect, the bottom of the outsole body 2 is also provided with several anti-slip patterns 22 to enhance anti-slip grip, which fully considers the usage needs under different ground conditions. The additional anti-slip patterns 22 further increase the contact area between the rubber outsole and the ground.

[0121] To ensure the stud assembly is securely fitted onto the rubber outsole, the outsole is primarily made of rare-earth cis-butadiene rubber and nitrile rubber. Rare-earth cis-butadiene rubber possesses extremely high elasticity and crystallization speed, good molecular chain flexibility, outstanding abrasion resistance, and low abrasion rate, making it particularly suitable for high-frequency friction scenarios where the sole is in long-term contact with the ground. Nitrile rubber, on the other hand, has high tear strength and tensile strength, enhancing the resistance to damage at the edges and bending points of the outsole and extending its service life. The complementary properties of these two materials result in a significant increase in the tear strength, tensile strength, elongation, and abrasion resistance of the rubber outsole. The specific properties of this rubber outsole are as follows:

[0122] Tear strength > 8kN / m

[0123] Tensile strength > 180 kg / cm²

[0124] Elongation > 600%

[0125] Abrasion resistance DIN<90mm³.

[0126] Example 2

[0127] For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus now is on the structure that is different from Embodiment 1 of this utility model. The difference between Embodiment 2 and Embodiment 1 is the adaptive shock absorption setting of the rubber outsole.

[0128] Figure 14 This is a partial cross-sectional view of a rubber outsole according to another embodiment of the present invention, as shown below. Figure 14 As shown, the shock absorption and anti-slip effect according to another embodiment of the present invention will be described in detail.

[0129] According to the present invention, a rubber outsole is provided, wherein the rubber outsole includes an outsole body 2, the outsole body 2 includes a first surface for contacting the ground and a second surface attached to the midsole of the shoe sole, and at least one embedded replaceable shock-absorbing and anti-slip device as described above is detachably provided on the first surface of the outsole body 2.

[0130] The first surface includes an anti-slip unit 21 extending from the outsole body 2 of the rubber outsole toward the ground to a first height H1, which is used to provide a first anti-slip force. When the foot contacts the ground, the anti-slip unit 21 can contact the ground first, increasing the contact area with the ground and closely conforming to the uneven structure of the ground, thereby increasing the friction of the first surface of the rubber outsole that contacts the ground and preventing slipping.

[0131] At least one anti-slip unit 21 includes an anti-slip block 211, which has a fitting groove 212 for detachably installing an embedded stud assembly 1. When the embedded stud assembly 1 is installed in the fitting groove 212, the stud assembly 1 extends from the outsole body 2 of the rubber outsole toward the ground to a height between a first height H1 and a second height H2, providing an adaptive second anti-slip force. When the foot contacts the ground, the stud assembly 1 makes contact with the ground first, providing the second anti-slip force. When the stud assembly 1 contacts various uneven ground surfaces (such as snow, dirt roads, rocky roads, or ice), the retractable anti-slip part 13 inside the stud assembly 1 can adapt to the unevenness of different ground surfaces to provide a stronger anti-slip force. Then, the anti-slip unit 21 contacts the ground to provide the first anti-slip force, providing more contact area with the ground, providing double anti-slip, suitable for contacting uneven ground surfaces (such as snow, dirt roads, rocky roads) in some extreme environments, providing a reliable anti-slip effect.

[0132] To achieve adaptive shock absorption, during walking, when the rubber outsole contacts the ground, the spring 132 of the stud assembly 1 adapts to the change in the center of gravity during walking, providing a height between the first height H1 and the second height H2. When walking on surfaces such as snow, dirt roads, or rocky roads, the center of gravity of the foot first concentrates on the heel. At this time, the stud assembly 1 located on the heel first contacts the ground. Due to the pressure, the anti-slip stud 131 retracts into the second receiving groove 122 through the elastic deformation of the spring 132. When the center of gravity of the foot transitions to the forefoot, the stud assembly 1 on the forefoot responds to the pressure, and the anti-slip stud 131 retracts into the second receiving groove 122 through the elastic deformation of the spring 132.

[0133] During this process, due to the different unevenness of the ground, when any anti-slip stud 131 of the stud assembly 1 protrudes relative to the ground, the elastic deformation of its spring 132 is relatively large, and the amount of spring 132 retraction is also relatively large, thus providing a height H3 between the first height H1 and the second height H2; when any other anti-slip stud 131 of the stud assembly 1 is concave relative to the ground, the elastic deformation of its spring 132 is relatively small, and the amount of spring 132 retraction is also relatively small, thus providing a height H4 between the first height H1 and the second height H2. At this time, the self-adaptation of any two stud assemblies 1 on the ground is manifested as heights H3 and H4 (H4 is greater than H3) between the first height H1 and the second height H2, thus completing the self-adaptation to different unevenness of the ground (when walking on any uneven ground, any stud assembly 1 will self-adapt to the ground through spring 132 and provide a height Hn between the first height H1 and the second height H2, where Hn satisfies H1≤Hn≤H1+H2).

[0134] The shock absorption effect is dynamically adjusted according to different walking conditions (such as heel strike or forefoot strike) to reduce the direct transmission of impact force to the feet. The spring 132 continuously makes elastic deformation in response to changes in the center of gravity, effectively cushioning the impact force of the ground on the soles of the feet during walking, greatly reducing the burden on joints such as knees and ankles during walking. On complex terrains such as snow, dirt roads, and rocky roads, it can also adjust in real time according to changes in the center of gravity to prevent slipping, thereby improving walking comfort and stability. It can provide reliable anti-slip protection whether starting, accelerating, decelerating or turning during movement.

[0135] [Shoe sole according to an embodiment of this utility model]

[0136] Example 1

[0137] Figure 15 This is a side view of the sole of a shoe according to an embodiment of the present invention. Figure 16 This is a top view of the midsole according to an embodiment of the present utility model, as shown below. Figure 15 and Figure 16 As shown, the midsole structure according to an embodiment of the present invention will be described in detail.

[0138] As another aspect of the present invention, a shoe sole is provided, further comprising a midsole 4 having a first surface for contacting the instep and a second surface for contacting a rubber outsole, wherein the second surface contacts the rubber outsole as described above, wherein the second surface of the midsole 4 has at least one groove 411 adapted to a protrusion 213 for receiving the protrusion 213.

[0139] Figure 17 This is a top view of the midsole according to an embodiment of the present utility model, as shown below. Figure 17 As shown, the groove structure according to an embodiment of the present invention will be described in detail.

[0140] To provide sufficient space, the groove 411 is used to provide space to accommodate the protrusion 213. The depth of this space is positively correlated with the height of the protrusion 213 of the tack assembly 1. The higher the height of the embedded tack assembly 1, the higher the protrusion 213 protrudes, and the deeper the groove 411 becomes. At the same time, the cooperation between the groove 411 and the protrusion 213 can increase the friction of the contact surface, ensuring that the protrusion 213 can be firmly embedded in the groove 411, thereby forming greater frictional resistance between the contact surfaces and preventing slippage.

[0141] To improve the durability of the sole, the outsole body 2 and the midsole 4 are bonded together using one of the following methods: adhesive bonding, hot melting, or stitching. This ensures the bonding strength and stability between the outsole body 2 and the midsole 4, while also improving the durability and production efficiency of the shoe.

[0142] Figure 9 A schematic diagram of the structure of the rubber outsole according to an embodiment of the present invention is shown below. Figure 9 As shown, the overall structure of the rubber outsole according to an embodiment of the present invention will be described in detail.

[0143] To ensure even force distribution on the sole, the embedded stud assembly 1 is arranged in a fractal geometric pattern at the forefoot of the sole within the anti-slip unit 21, with at least two stud assemblies 1 centered around it. This provides the propulsive force needed for greater grip in the forefoot area during exercise (such as walking on muddy roads, mountain climbing, or walking on ice). The embedded stud assembly 1 is also arranged in a fractal geometric pattern at the heel of the sole within the anti-slip unit 21, with at least one stud assembly 1 centered around it. This provides the stability needed in the heel area during exercise (such as walking on muddy roads, mountain climbing, or walking on ice) to disperse impact force. This arrangement also conforms to the force distribution characteristics of the human body during movement, ensuring that the sole maintains good grip and stability in various sports scenarios.

[0144] To improve production efficiency, the outsole body 2, midsole 4 and stud assembly 1 are processed in layers. The outsole body 2 and midsole 4 are processed first, and then the stud assembly 1 and outsole body 2 are processed and assembled. The processing is convenient and quick during production. Each component can be processed with high precision individually, avoiding the loss caused by overall processing, thereby significantly improving the product yield, reducing material waste, and reducing production costs.

[0148] In this embodiment, the device can be specifically applied to trekking poles. The device can effectively absorb impact force when the trekking pole contacts the ground, reducing the amplitude of vibration transmitted to the user's wrist and shoulder.

[0149] It can also be applied to anti-slip gloves. On smooth ice surfaces or steep rocks, anti-slip gloves equipped with this device can provide extra grip, significantly increase friction, and prevent hands from slipping.

[0150] It can also be applied to the soles of robots. When a robot is walking, by placing this device on the soles of its feet, it can provide additional grip, significantly increase friction, prevent slipping, and avoid falling due to the slippery ground when moving.

[0151] It can also be applied to the bottom of outdoor camping boxes. When camping outdoors in icy and snowy conditions, by installing this device at the bottom of the outdoor box, it can provide extra grip, significantly increase friction, and prevent the box from sliding during movement or use.

[0152] It can also be applied to toy car tires. When players control toy cars, taking remote control cars as an example, by setting this device on the tires, the vehicle's grip and stability on various terrains can be improved, making it less likely for the vehicle to slip during remote control driving. It can better maintain the balance and control of the toy vehicle, even on wet or muddy roads.

[0153] [How to use the shoe sole with the embedded replaceable shock-absorbing and anti-slip device according to the embodiment of this utility model]

[0154] Method A of using the shoe sole with embedded replaceable shock absorption and anti-slip device

[0155] When used on ice, the spike assembly 1 installed on the outsole of the shoe provides strong anti-slip force. Specifically, the anti-slip spike 131 of the spike assembly 1 first contacts the ground, providing a second anti-slip force and increasing the contact area with the ice surface. The spike assembly 1 can penetrate the ice surface and contact the lower layer of the ice surface to provide stronger anti-slip force. Then, the anti-slip unit 21 contacts the ice surface to provide a first anti-slip force, providing more contact area with the ground. This double anti-slip effect, combined with the spring 132, can adapt to different ice surface textures and effectively improve the anti-slip effect on ice.

[0156] Method B of using shoe soles with embedded replaceable shock absorption and anti-slip devices

[0157] When used on rocky and dirt roads, the nail assembly 1 installed on the outsole of the shoe provides strong anti-slip force on these surfaces. Specifically, the anti-slip nail 131 of the nail assembly 1 first contacts the ground, providing a second anti-slip force and increasing the contact area with the rocky and dirt road to provide stronger anti-slip force. Then, the anti-slip unit 21 contacts the rocky and dirt road to provide a first anti-slip force, providing even more contact area with the ground. This double anti-slip design, combined with the spring 132, allows for self-adaptation to different uneven rock surfaces, effectively improving the anti-slip effect on rocky and dirt roads.

[0158] When walking or exercising on uneven surfaces, any nail component 1 will adapt to the ground via spring 132. Spring 132 continuously makes elastic deformation to change the center of gravity, providing a height Hn between the first height H1 and the second height H2, where Hn satisfies H1≤Hn≤H1+H2. This effectively buffers the impact force of the ground on the soles of the feet when walking, and adjusts in real time according to changes in the center of gravity and the unevenness of the ground, providing strong anti-slip force and reliable sports protection.
