Description

Technical Field

[0001] This invention relates to the field of footwear technology, and more specifically to a puncture-resistant safety work shoe. Background Technology

[0002] Safety shoes are a type of footwear that provides safety protection for the feet. There are many types, such as those that protect the toes, prevent punctures, provide insulation, and are resistant to acids and alkalis. The puncture-proof function of safety shoes is mainly achieved through puncture-proof structures (such as steel plates, Kevlar fibers, etc.) set inside the sole, which can effectively resist the penetration of sharp objects such as nails, metal fragments, and glass, ensuring that workers can work safely in environments where there is a risk of sharp objects.

[0003] The outer layer of the sole is usually made of abrasion-resistant rubber or polyurethane, providing grip and oil resistance. The midsole is embedded with a steel midsole or Kevlar fiber layer as a puncture-resistant core. The inner layer of the sole is filled with soft materials (such as microfiber leather or wool) to improve comfort and reduce stuffiness. Due to the characteristics of the materials used in work shoes, the soles of work shoes have poor breathability. To effectively promote the evaporation of foot sweat and reduce stuffiness, ventilation holes are often set at the bottom of the upper. This is because foot sweat mainly concentrates on the soles of the feet, and the bottom of the upper is close to the soles of the feet. Therefore, placing ventilation holes here can more directly and effectively expel sweat and heat generated on the soles of the feet, keeping the soles of the feet dry in time.

[0004] Currently, when workers wear these safety shoes and walk on wet surfaces, the ventilation holes are located at the bottom of the shoe upper, which is quite low. When the sole contacts the ground, the water is squeezed and splashes outwards. Some water droplets can easily enter the shoe through the low ventilation holes. The damp environment inside the shoe makes the feet sticky and cold, affecting the worker's endurance for standing and walking for long periods. Furthermore, the damp environment provides a breeding ground for fungi such as Trichophyton rubrum, causing peeling between the toes, blisters, and itching, increasing the worker's discomfort. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a puncture-resistant safety work shoe that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a puncture-resistant safety work shoe, comprising: The shoe body has a shoe frame fixedly connected to its bottom, and a shoe sole is fixedly connected to its bottom. The shoe frame includes an outer frame, an inner frame, an outer partition, and an inner partition. The bottoms of the outer frame, inner frame, outer partition, and inner partition are fixedly connected to the upper surface of the sole. The outer frame, outer partition, inner partition, and inner frame are distributed sequentially from the outside to the inside on the upper surface of the sole. The outer surface of the outer frame has a breathable outer hole, the outer surface of the inner frame has a breathable inner hole, the outer and inner partitions have a breathable middle hole on their outer surfaces, a sliding strip is slidably connected between the outer frame and the outer partition, and breathable mesh strips and waterproof sealing sheets are evenly distributed on the outer surface of the sliding strip.

[0007] Furthermore, the outer surface of the outer frame is provided with a dust outlet hole, the outer surface of the outer partition is provided with a perforation, the outer surface of the inner partition is provided with a through groove, a compression piece is slidably connected inside the through groove, and a puncture is fixedly connected to the side of the compression piece near the perforation, the puncture being located inside the perforation.

[0008] Furthermore, an elastic block is fixedly connected to the side of the extrusion piece away from the puncture, and the end of the elastic block away from the extrusion piece is fixedly connected to the inner frame.

[0009] Furthermore, a sliding upper strip is slidably connected between the inner partition and the inner frame, and an arc-shaped patch is fixedly connected to the side of the sliding upper strip away from the inner frame.

[0010] Furthermore, two pull plates are fixedly connected to the outer surface of the shoe body. Each pull plate has an outer pull strip and an inner pull strip slidably connected to its inner wall. A pull line is slidably connected between the outer pull strip and the inner pull strip. An outer pull line is fixedly connected to the bottom end of each of the two outer pull strips. An inner pull line is fixedly connected to the bottom end of each of the two inner pull strips. The end of the outer pull line away from the outer pull strip passes through the outer frame and is fixedly connected to one end of the sliding strip. The end of the inner pull line away from the inner pull strip passes through the outer frame, the outer partition, and the inner partition in sequence and is fixedly connected to one end of the sliding upper strip. A middle pull line is fixedly connected between the bottom ends of the two pull lines. A pull ring is fixedly connected to the top end of each of the two pull lines.

[0011] Furthermore, the outer surface of the outer strip of the pull wire is fixedly connected with a first push bar and a second push bar, the outer surface of the inner strip of the pull wire is fixedly connected with a third push bar and a fourth push bar, and the outer surface of the pull wire plate is fixedly connected with a first stop bar, a second stop bar, a third stop bar, and a fourth stop bar.

[0012] Furthermore, two adjusting blocks are rotatably connected to the outer surface of the pull line. An adjusting outer strip and an adjusting inner strip are fixedly connected to the outer circumference of each adjusting block. The adjusting outer strip is used to push the first or second pushing strip to drive the outer strip of the pull line to slide, and the adjusting inner strip is used to push the third or fourth pushing strip to drive the inner strip of the pull line to slide.

[0013] Furthermore, the end of the adjusting block is rotatably connected to a turntable wheel, the outer surface of the pull plate is fixedly connected to an adjusting slide rail, and the turntable wheel is slidably connected inside the adjusting slide rail.

[0014] Furthermore, the adjusting slide rail includes a first straight rail, a second straight rail, a third straight rail, a first inclined rail, a second inclined rail, and a third inclined rail. The top end of the first straight rail is fixedly connected to the bottom end of the first inclined rail, the top end of the first inclined rail is fixedly connected to the bottom end of the second straight rail, the top end of the second straight rail is fixedly connected to the bottom end of the second inclined rail, the top end of the second inclined rail is fixedly connected to the bottom end of the third straight rail, and the top end of the third straight rail is fixedly connected to the bottom end of the third inclined rail.

[0015] Furthermore, two sets of retaining strips are fixedly connected to the outer surface of the pull wire plate, and an inner U-shaped strip and an outer U-shaped strip are slidably connected to the outer surfaces of both the outer and inner pull wire strips. Elastic elements are fixedly connected to the outer surfaces of both the outer and inner pull wire strips, and the telescopic ends of the elastic elements are fixedly connected to the inner U-shaped strips. Gears are rotatably connected to the outer surfaces of both the outer and inner pull wire strips, and teeth are provided on the outer side of the inner U-shaped strip and the inner side of the outer U-shaped strip.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention embeds high-strength protective materials inside the sole of the shoe. These materials combine the toughness of metal with the high strength and lightweight properties of fibers to form a protective structure that is puncture-resistant, wear-resistant, shock-absorbing, and has a controllable weight. The puncture-resistant sole can block nails and steel fragments on the ground, protecting the worker's foot safety, while the lightweight design reduces the burden on the worker's walking.

[0017] 2. This invention incorporates breathable inner holes, breathable middle holes, breathable mesh strips, and breathable outer holes in the shoes. When workers walk, the alternating lifting and stomping of the feet creates a pressure difference between the inside and outside of the shoe. The breathable inner holes, middle holes, mesh strips, and outer holes act as air channels, allowing cold air from outside to be drawn into the shoe when the foot is lifted and hot air to be squeezed out when the foot is stomped, thus creating a continuous air circulation. The breathable holes also introduce dry air from outside, promoting the diffusion of sweat from the skin surface into the air and reducing the stuffiness of the workers' feet.

[0018] 3. This invention features multiple waterproof seals on both sides of the shoe body. These seals block the ventilation holes on the shoe frame, preventing rainwater from entering the shoe through the lower ventilation holes. This effectively prevents rainwater from contacting the skin, reduces the stickiness and discomfort caused by wet feet, enhances the waterproof performance of the shoe body, keeps feet dry, and significantly improves the wearing comfort and foot health of the shoe body.

[0019] 4. This invention incorporates punctures inside the perforations. These punctures "pierce" the breathable mesh strips, allowing multiple punctures to clear dust and impurities adhering to the breathable mesh strips on both sides of the shoe, thereby increasing the airflow area on the breathable mesh strips and enhancing their breathability.

[0020] 5. This application incorporates locking strips on both sides of the pull tab. During the transition from waterproof to breathable mode, the locking strips and inner U-shaped strips on one side of the pull tab are unlocked first, followed by the locking strips and inner U-shaped strips on the other side. The inner pull tab, inner pull line, and upper sliding strip are pulled first, followed by the outer pull tab, outer pull line, and sliding strip. This orderly repositioning of the puncture and breathable mesh strips is achieved by pulling the pull ring once. The locking strips and inner U-shaped strips on both sides of the pull tab are unlocked sequentially, ensuring the orderly repositioning of the puncture and breathable mesh strips. This prevents tearing damage to the breathable mesh strips caused by punctures and further improves the protective effect of the breathable mesh strips. Attached Figure Description

[0032] Two adjusting blocks 6 are rotatably connected to the outer surface of the pull wire 43. An adjusting outer strip 61 and an adjusting inner strip 62 are fixedly connected to the outer circumference of the adjusting blocks 6 respectively. The adjusting outer strip 61 is used to push the first pushing strip 5 or the second pushing strip 51 to drive the pull wire outer strip 41 to slide.

The top end of the first straight rail 711 is fixedly connected to the bottom end of the first inclined rail 714, the top end of the first inclined rail 714 is fixedly connected to the bottom end of the second straight rail 712, the top end of the second straight rail 712 is fixedly connected to the bottom end of the second inclined rail 715, the top end of the second inclined rail 715 is fixedly connected to the bottom end of the third straight rail 713, and the top end of the third straight rail 713 is fixedly connected to the bottom end of the third inclined rail 716.

The outer side of the inner U-shaped strip 81 and the inner side of the outer U-shaped strip 82 are provided with teeth 85.

[0036] Working principle: The puncture resistance of sole 1: In practical applications, sharp objects such as nails, steel rebar fragments, and glass shards are often scattered on the ground at construction sites. When workers wear ordinary shoes and walk on the ground where sharp objects are scattered, the sharp objects can easily pierce the soles of their shoes, causing serious foot injuries. Foot puncture wounds are not only extremely painful, but can also easily lead to complications such as infection and tetanus, affecting the health and work efficiency of workers.

[0037] To overcome the above difficulties, this application adopts the following technical solution: This application embeds a high-strength protective material inside the sole 1. This high-strength protective material is a composite material formed by embedding high-strength fibers (such as carbon fiber and glass fiber) into a metal (such as aluminum or titanium alloy) matrix. This type of material combines the toughness of the metal with the high strength and lightweight properties of the fibers to form a protective structure that is puncture-resistant, wear-resistant, shock-absorbing, and has a controllable weight. The puncture-resistant sole 1 can block nails and steel fragments on the ground, protecting the worker's foot safety, while the lightweight design reduces the burden on the worker's walking.

[0038] The breathability of sole 1: In practical applications, in dry working environments such as indoor decoration, dry concrete pouring sites, and carpentry workshops, when workers wear the shoe body 12 and walk on dry ground, in order to effectively promote the evaporation of foot sweat and reduce stuffiness, this application adopts the following technical solution: like Figure 1 , Figure 2 and Figure 10 As shown, this application controls the position of the sliding strip 27 between the outer frame 2 and the outer partition 22, so that the breathable mesh strip 28 is located between the outer breathable hole 24 and the middle breathable hole 26. At this time, the gas inside the shoe body 12 can exchange with the outside air through the inner breathable hole 25, the middle breathable hole 26, the breathable mesh strip 28 and the outer breathable hole 24 in sequence. Especially when the worker walks, the alternating lifting and stepping of the foot will create a pressure difference between the inside and outside of the shoe body 12. The inner breathable hole 25, the middle breathable hole 26, the breathable mesh strip 28 and the outer breathable hole 24 act as air channels, so that the cold air outside is drawn into the shoe body 12 when the foot is lifted, and the hot air inside the shoe body 12 is squeezed out when stepping, forming a continuous air circulation. The vents introduce dry air from the outside, promote the diffusion speed of sweat from the skin surface to the air, and reduce the stuffiness of the worker's feet.

[0039] Waterproof function of sole 1: In practical applications, during rainy weather, the ground is slippery and rainwater tends to accumulate in low-lying areas. To prevent rainwater from entering the shoe body 12 through the ventilation holes when walking on wet ground, this application adopts the following technical solution: like Figure 1 , Figure 2 and Figure 3 As shown, the worker pulls one of the loops 47 on the back of the shoe body 12 upwards (this loop 47 is...). Figure 2 The pull ring 47 on the left side of the middle pull ring 47 drives the pull line 43 at its bottom to move upward between the outer pull line 41 and the inner pull line 42. At this time, if Figure 5 and Figure 6As shown, under the limiting action of the adjusting slide rail 71 (the upper actuating wheel 7 is slidably connected to the second straight rail 712, and the lower actuating wheel 7 is slidably connected to the first straight rail 711), neither of the two adjusting blocks 6 can rotate around its own axis. The upper adjusting block 6 drives the adjusting outer strip 61 on its circumferential outer surface to be located on the side of the first push bar 5 closer to the second push bar 51, and the lower adjusting block 6 drives the adjusting outer strip 61 on its circumferential outer surface to be located on the side of the second push bar 51 closer to the first push bar 5. Therefore, the upward movement of the pulling line 43 drives the two adjusting blocks 6 on its outer surface to move upward, and the upper adjusting block 6 pushes the first push bar 5 upward through the adjusting outer strip 61 on its circumferential outer surface. The first push bar 5 drives the outer pull bar 41 and the second push bar 51 to move upward. Under the connection of the middle pull bar 46, the upward-moving pull bar 43 drives the other pull bar 43 to move downward through the middle pull bar 46. At the same time as the other pull bar 43 moves downward, the technical effect brought about by the upward-moving pull bar 43 is opposite. The other downward-moving pull bar 43 drives the other pull bar 41 to move downward. Thus, the two pull bar outer bars 41 drive the sliding strip 27 to slide a certain distance between the outer frame 2 and the outer partition 22 through the outer pull bar 44 at their bottom ends. This continues until the breathable mesh strip 28 on the sliding strip 27 is aligned with the dust outlet hole 3 on the outer frame 2, and the waterproof sealing strip 29 on the sliding strip 27 is located between the breathable outer hole 24 and the breathable middle hole 26. At this time, the state of the pull bar plate 4 is as follows: Figure 6 As shown, multiple waterproof seals 29 on both sides of the shoe body 12 seal the ventilation holes on the shoe frame 11, preventing rainwater from entering the shoe through the lower ventilation holes, effectively preventing rainwater from contacting the skin, reducing the stickiness and discomfort caused by "wet feet", enhancing the waterproof performance of the shoe body 12, keeping the feet dry, and significantly improving the wearing comfort and foot health of the shoe body 12.

[0040] Dust removal function of sole 1: In practical applications, during rainy weather, the air humidity is high, and the ground dust mixes with rainwater to form mud and wet particles. These particles have increased surface tension and easily adhere to the fiber surface of the shoe upper mesh, forming a "mud film" or "scale layer," which directly blocks the mesh channels. Furthermore, when workers walk, the rainwater kicked up by the soles of the shoes splashes onto the shoe upper, re-adhering ground dirt (such as mud, oil stains, and debris) to the mesh. Even if the mesh is not completely blocked, the wet dirt will cover the fiber surface, reducing the air circulation area and thus reducing the breathability of the ventilation holes.

[0041] To overcome the above difficulties, this application adopts the following technical solution: like Figure 6 , Figure 7 and Figure 8As shown, by further pulling the pull ring 47, the pull ring 47 drives the pull line 43 below it to move further upward. At this time, as mentioned above, the waterproof seal 29 is located between the ventilated outer hole 24 and the ventilated middle hole 26, while the ventilated mesh strip 28 is located inside the dust outlet hole 3, and the side of the ventilated mesh strip 28 away from the dust outlet hole 3 is the perforation 31. The puncture 34 is located inside the perforation 31. The upward-moving pull line 43 drives the two adjusting blocks 6 on its outer surface to move upward, as shown. Figure 6 As shown, the upper adjusting block 6 drives the upper actuating wheel 7 to slide upward along the second inclined rail 715, and the lower adjusting block 6 drives the lower actuating wheel 7 to slide upward along the first inclined rail 714. Under the limiting action of the adjusting slide rail 71, the adjusting slide rail 71 drives the upper actuating wheel 7 and the upper adjusting block 6 to rotate around the axis of the adjusting block 6 through the second inclined rail 715, and the adjusting slide rail 71 drives the lower actuating wheel 7 and the lower adjusting block 6 to rotate around the axis of the adjusting block 6 through the first inclined rail 714. When the upper adjusting block 6 and the lower adjusting block 6 rotate 90 degrees around their own axes, as... Figure 7 As shown, at this time, the upper adjusting block 6 causes the adjusting inner strip 62 on its outer circumference to be positioned on the side of the third pushing strip 52 closer to the fourth pushing strip 53, and the lower adjusting block 6 causes the adjusting inner strip 62 on its outer circumference to be positioned on the side of the fourth pushing strip 53 closer to the third pushing strip 52. The pull line 43 continues to drive the two adjusting blocks 6 to move upward, as shown. Figure 7 and Figure 8 As shown, the upper adjusting block 6 drives the upper actuating wheel 7 to slide and connect with the third straight rail 713, and the lower adjusting block 6 drives the lower actuating wheel 7 to slide and connect with the second straight rail 712. In summary, the adjusting slide rail 71 limits the two adjusting blocks 6 through the actuating wheel 7 (neither of the two adjusting blocks 6 can rotate around its own axis). Therefore, the upward-moving pull line 43 drives the two adjusting blocks 6 on its outer surface to move upward. The upper adjusting block 6 pushes the third push bar 52 upward through the adjusting inner bar 62 on its outer circumference. The third push bar 52 drives the inner pull bar 42 and the fourth push bar 53 to move upward. Under the connection of the middle pull bar 46, the upward-moving pull bar 43 drives another pull bar 43 to move downward through the middle pull bar 46. Simultaneously, the downward movement of the other pull bar 43 has the opposite effect to the upward movement of the pull bar 43; it drives another inner pull bar 42 to move downward. This allows the two inner pull bars 42 to slide a distance between the inner partition 23 and the inner frame 21 via the inner pull bar 45 at their bottom ends. Figure 8As shown, when the upper adjusting inner strip 62 pushes the third pushing strip 52 to contact the third stop strip 56, the pull ring 47 stops being pulled. At this time, the moving sliding upper strip 36 drives the arc-shaped patch 37 on its outer surface to move to the center of the side of the extrusion piece 33 away from the puncture 34. Under the extrusion action of the arc-shaped patch 37, multiple arc-shaped patches 37 push the extrusion piece 33 along the groove 32 toward the perforation 31. The moving multiple extrusion pieces 33 drive the puncture 34 on one side to pass through the perforation 31 and into the mesh of the breathable mesh strip 28. Under the "piercing" action of the puncture 34 on the breathable mesh strip 28, multiple punctures 34 clear the dust and impurities adhering to the breathable mesh strip 28 on both sides of the shoe body 12, thereby increasing the air circulation area on the breathable mesh strip 28 and enhancing the breathability of the breathable mesh strip 28.

[0042] As a further embodiment of the present invention, when a worker wears the shoe body 12 and walks, it is necessary to switch between the waterproof mode and the breathable mode on the shoe body 12. During the switching process from the breathable mode to the waterproof mode, such as Figure 5 As shown, the upper outer U-shaped strip 82 is not squeezed by the adjusting inner strip 62. At this time, the upper inner U-shaped strip 81 is pulled by the elastic element 83 under the elastic action of the elastic element 83 so that its two ends contact the pull plate 4 (the upper inner U-shaped strip 81 is in an extended state). However, the lower outer U-shaped strip 82 is squeezed by the adjusting outer strip 61, which limits the lower inner U-shaped strip 81 so that its two ends do not contact the pull plate 4 (the lower inner U-shaped strip 81 is in a contracted state). As the adjusting block 6 moves upward, the adjusting block 6 drives the pull outer strip 41 to move upward through the adjusting outer strip 61. The inner U-shaped strip 81 on the pull outer strip 41 moves upward in a contracted state, as shown. Figure 6 and Figure 7 As shown, during the sliding of the actuating wheel 7 along the second inclined rail 715, the adjusting block 6 drives the adjusting outer strip 61 and the adjusting inner strip 62 to rotate around the axis of the adjusting block 6. During this process, the adjusting outer strip 61 releases the squeezing action on the left outer U-shaped strip 82 and releases the restriction on the left inner U-shaped strip 81. Under the elastic action of the left elastic element 83, the left elastic element 83 pulls the left inner U-shaped strip 81 so that its two ends enter the interior of the left retaining strip 8, thus restricting the outer strip 41 of the pull wire. Positioned with the outer bar 41 of the pull cable fixed on the pull plate 4, the inner bar 62 gradually presses against the right outer U-shaped bar 82. The right outer U-shaped bar 82, through its inner teeth 85, drives the right gear 84 to rotate on the inner bar 42. The rotating gear 84, through the outer teeth 85 of the inner U-shaped bar 81, drives the inner U-shaped bar 81 to overcome the elastic force of the elastic element 83 and slide on the inner bar 42, causing the right inner U-shaped bar 81 to be in a contracted state. The adjusting block 6 continues to move upwards. Figure 8 and Figure 9As shown, after the right inner U-shaped strip 81 and the right locking strip 8 are "aligned", the adjusting block 6 continues to move upward. The adjusting block 6 drives the actuating wheel 7 to slide upward along the third inclined rail 716. At this time, under the limiting action of the third inclined rail 716, the actuating wheel 7 drives the adjusting block 6 to rotate around its own axis. The adjusting block 6 drives the adjusting inner strip 62 to rotate around the axis of the adjusting block 6, releasing the squeezing action of the adjusting inner strip 62 on the right outer U-shaped strip 82 and releasing the limiting action on the right inner U-shaped strip 81. Under the elastic action of the right elastic element 83, the right elastic element 83 pulls the right inner U-shaped strip 81 so that its two ends enter the interior of the right locking strip 8, limiting the inner strip 42 of the pull wire. The position of the inner strip 42 of the pull wire on the pull wire plate 4 remains fixed. This application achieves this by "inserting" the left locking strip into the left inner U-shaped strip 81. Between 8, the outer strip 41 of the pull cord is fixed to the pull cord plate 4. The inner U-shaped strip 81 on the right is "inserted" between the right-side clips 8, thereby fixing the inner strip 42 of the pull cord to the pull cord plate 4. Then, the breathable mesh strip 28 is moved to the piercing position and fixed. Then, the piercing 34 pierces and clears the mesh on the breathable mesh strip 28. Conversely, when switching from waterproof mode to breathable mode, the left clips 8 and inner U-shaped strip 81 are unlocked first, and then the right clips 8 and inner U-shaped strip 81 are unlocked. The inner strip 42 of the pull cord 45, the inner pull cord 45 and the sliding upper strip 36 are pulled first, and then the outer strip 41 of the pull cord 44, the outer pull cord 44 and the sliding strip 27 are pulled. This orderly resets the piercing 34 and the breathable mesh strip 28. By pulling the pull ring 47 once (this pull ring 47 is... Figure 2 The pull ring 47 on the right side of the middle can be used to unlock the locking strip 8 and the inner U-shaped strip 81 on both sides of the pull plate 4, thereby completing the orderly reset of the puncture 34 and the breathable mesh strip 28, preventing the puncture 34 from tearing the breathable mesh strip 28, and further improving the protective effect of the breathable mesh strip 28.

[0043] As a further embodiment of the present invention, when the weather is sunny and the water on the ground has completely evaporated, another pull ring 47 is pulled upwards (this pull ring 47 is...). Figure 2 As mentioned above, the pull ring 47 on the right side of the center, under the connection of the center pull line 46, Figure 2The pull line 43 on the left side of the middle will move downward. At this time, the downward movement of the pull line 43 will drive the two adjusting blocks 6 on its outer surface to move downward. Under the limiting action of the third straight rail 713 and the second straight rail 712, the two downward moving adjusting blocks 6 still cannot rotate around their own axis. The lower adjusting block 6 pushes the fourth pushing bar 53 downward through the lower adjusting inner bar 62. The fourth pushing bar 53 drives the inner bar 42 and the third pushing bar 52 downward. At this time, as mentioned above, the two inner bars 42 pull the sliding upper bar 36 in the opposite direction through the inner pull line 45 to slide a distance between the inner partition 23 and the inner frame 21, so that the sliding upper bar 36... 6. "Reset": Release the limiting effect of the arc-angle patch 37 on the extrusion piece 33. Under the elastic action of the elastic block 35 itself, the elastic block 35 drives the extrusion piece 33 and the puncture 34 to move closer to the inner frame 21. The puncture 34 re-enters the interior of the perforation 31 (the puncture 34 separates from the breathable mesh strip 28), releasing the obstruction of the puncture 34 on the breathable mesh strip 28 (the sliding strip 27 can drive the breathable mesh strip 28 to slide between the outer frame 2 and the outer partition 22). When the two adjusting blocks 6 drive the upper actuating wheel 7 to slide down along the second inclined rail 715 and the lower actuating wheel 7 to slide down along the first inclined rail 714, as described above, the two adjusting blocks 6 begin to rotate around their own axes, making the adjustment... The upper adjusting ring 61 rotates to the side of the first pushing ring 5 closest to the second pushing ring 51, and the lower adjusting ring 61 rotates to the side of the second pushing ring 51 closest to the first pushing ring 5. Then, the two adjusting rings 6 continue to move downwards. The upper actuating wheel 7 slides downwards along the second straight rail 712, and the lower actuating wheel 7 slides downwards along the first straight rail 711. The two adjusting rings 6 cannot rotate around their own axes. At this time, the lower adjusting ring 6 drives the second pushing ring 51 downwards via the lower adjusting ring 61. The second pushing ring 51 drives the pull wire outer ring 41 and the first pushing ring 5 downwards. As described above, this completes the sliding action. When the moving strap 27 is pulled in the opposite direction, the sliding strap 27 causes the breathable mesh strip 28 to reposition itself between the outer breathable hole 24 and the middle breathable hole 26. This allows for a single pull, enabling the double unlocking of the locking strip 8 and the inner U-shaped strip 81 located on both sides of the pull plate 4. This, in turn, completes the orderly reset of the puncture 34 and the breathable mesh strip 28, preventing the puncture 34 from causing tearing damage to the breathable mesh strip 28 and further improving the protective effect of the breathable mesh strip 28. At this time, the gas inside the shoe body 12 can exchange with the outside air in sequence through the inner breathable hole 25, the middle breathable hole 26, the breathable mesh strip 28, and the outer breathable hole 24, thus enabling the free switching between the waterproof mode and the breathable mode on the shoe body 12.
