Technical Field
[0001] This utility model relates to the field of safety shoe technology, specifically a safety shoe with a nanocomposite toe. Background Technology
[0002] Safety shoes are a type of footwear with special protective functions, primarily used to protect the feet from various potential injuries in work or other specific environments. They are widely used in various industrial fields and special working environments where workers face various hazards that can injure their feet. As an important component of personal protective equipment, safety shoes can effectively protect foot safety and reduce the occurrence of workplace accidents. However, existing safety shoes have drawbacks: they use relatively hard soles, which generate significant impact during use, potentially leading to occupational injuries after prolonged use. Furthermore, existing safety shoes are available in low-cut and high-cut versions, requiring workers to carry two pairs for frequent changes in different work environments, which is inconvenient. Existing safety shoes have limited functionality and are difficult to locate in dark environments. To address these shortcomings, existing technology (Chinese patent application number: 201920376848.2, authorized on 2019-12-13) addresses this by creating an installation groove at the top of the sole. A puncture-resistant steel plate is fixedly connected to the bottom of the groove's inner wall, a fastening pad is fixedly connected to the top of the steel plate, and an elastic pad is fixedly connected to the top of the fastening pad. The elastic pad contains elastic rubber particles. This structural design effectively protects the worker's feet, and thanks to the elastic pad and rubber particles, even prolonged wear will not cause occupational injuries, making the shoes comfortable to use.
[0003] Existing technology protects workers' insteps with puncture-resistant steel plates, but the strength and impact resistance of the toe area are relatively limited. This makes ordinary toe areas prone to deformation and cracking when subjected to external impacts or compression, failing to provide sufficient protection for the toes. Furthermore, the soles, in prolonged contact with the ground, are prone to wear, thinning, and even perforation, which damages the overall structure of the safety shoes and significantly shortens their lifespan. Therefore, we propose safety shoes with nanocomposite toe caps that can effectively solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a safety shoe with a nanocomposite toe, in order to solve the problems mentioned in the background art, where the strength and impact resistance of the toe area are relatively limited, making it easy for ordinary toe areas to deform or crack when subjected to external impact or compression, failing to provide sufficient protection for the toes. Furthermore, the sole is in contact with the ground for a long time, which can easily lead to wear, thinning, or even perforation, thus damaging the overall structure of the safety shoe and greatly shortening its service life.
[0005] To achieve the above object, the present utility model provides the following technical solutions: A safety shoe with a nano-composite toe cap, including a sole, the top of the sole is stitched and connected to a shoe upper, and a toe cap is provided at the front end of the shoe upper; further comprising: An energy absorption layer is stitched and connected to the inner side of the toe cap, the bottom of the sole is connected with a wear-resistant layer, and blocks are evenly fixed on the upper surface of the wear-resistant layer, grooves are evenly opened on the lower surface of the sole, limiting plates are evenly arranged inside the sole, grooves are opened on the side surfaces of the limiting plates, and a first spring is installed between the end of the limiting plate and the inner wall of the sole. On both the front and rear sides inside the sole, driving rods are slidably connected, and a second spring is installed between the outer side of the driving rod and the inner wall of the sole.
[0006] Preferably, the toe cap is composed of an inner layer, an intermediate layer and an outer layer. The upper surface of the inner layer is heat-sealed and connected to the intermediate layer, and the outer layer is heat-sealed and connected to the side of the intermediate layer away from the inner layer.
[0007] Preferably, the inner layer is a buffer layer, the intermediate layer is a nano-composite protection layer, and the outer layer is a waterproof and oil-proof coating.
[0008] Preferably, the energy absorption layer is made of polyurethane foam material, which can further reduce the impact force on the toes.
[0009] Preferably, a shock-absorbing layer is provided above the inside of the sole, and the shock-absorbing layer is made of EVA material.
[0010] Preferably, anti-slip patterns are provided on the lower surface of the wear-resistant layer. The blocks and the grooves are in snap-fit connection. The limiting plates are slidably arranged inside the sole, and the positions of the limiting plates and the limiting grooves correspond to each other.
[0011] Preferably, the grooves on the limiting plates are inclined, the end of the driving rod is in contact with the inner wall of the groove, the driving rod is arranged in a "匚" shape, and the side surface of the driving rod extends out of the outer surface of the sole.
[0012] Compared with the prior art, the beneficial effects of the present utility model are: The safety shoe with a nano-composite toe cap adopts a novel structural design, and the specific content is as follows:
[0013] (1) The toe area adopts a multi-layer composite structure design, in which the outer layer is a waterproof and oil-proof coating, the middle layer is a nano-composite protective layer, and the inner layer is a soft cushioning layer. This allows the toe to have good protective performance while also being waterproof, oil-proof, and comfortable to wear. Furthermore, an energy absorption layer made of polyurethane foam or gel is set inside the toe near the toes. When the toe is impacted, this material can absorb and dissipate energy through its own deformation, further reducing the impact on the toes and improving the protective effect.
[0014] (2) By setting the shock-absorbing layer inside the sole, the reaction force generated by the ground when walking, standing or exercising can be effectively buffered, reducing the vibration and impact on the feet, making the wearer feel more comfortable.
[0015] (3) The wear-resistant layer on the sole can withstand the friction of the ground and the wear of various complex working environments, greatly extending the service life of the sole. At the same time, the bottom of the wear-resistant layer is designed with anti-slip patterns, thereby providing reliable friction, reducing the risk of slipping, and ensuring the safety of the wearer.
[0016] (4) When the wear-resistant layer needs to be replaced, simply press the two drive rods so that the ends of the drive rods are inserted into the grooves on the limiting plate, causing the limiting plate to move and separate from the limiting groove, releasing the limiting of the locking block. Then, pull down the wear-resistant layer to remove it from the sole, which makes it easy to replace the wear-resistant layer and extend the overall service life of the shoes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-6 The present invention provides the following technical solution: a safety shoe with a nanocomposite toe;
[0026] Example 1: To address the issue that the strength and impact resistance of the toe section 3 in existing technologies are relatively limited, making it prone to deformation and breakage under external impact or compression, thus failing to provide sufficient protection for the toes, and that the sole 1, in prolonged contact with the ground, is prone to wear, thinning, and even perforation, which damages the overall structure of the safety shoe and significantly shortens its lifespan, the following solution is disclosed. Please refer to the following for details. Figure 1 and Figure 3 As shown, the shoe includes a sole 1, with an upper 2 sewn to the top of the sole 1. The upper 2 has a toe cap 3 at its front end. The toe cap 3 is composed of an inner layer 301, a middle layer 302, and an outer layer 303. The upper surface of the inner layer 301 is heat-sealed with the middle layer 302, and the side of the middle layer 302 away from the inner layer 301 is heat-sealed with the outer layer 303. The inner layer 301 is a cushioning layer, the middle layer 302 is a nano-composite protective layer, and the outer layer 303 is a waterproof and oil-resistant coating. The shoe also includes an energy absorption layer 4 sewn to the inner side of the toe cap 3. The energy absorption layer 4 is made of polyurethane foam material, which can further reduce the impact on the toes. The bottom of the sole 1 is connected to a wear-resistant layer 5.
[0027] When the user wears safety shoes for work, the toe 3 is designed with a multi-layer composite structure. The outer layer 303 has a coating with waterproof and oil-proof functions, the middle layer 302 is a nano-composite protective layer, and the inner layer 301 is a soft buffer layer. Thus, the toe 3 can have good protective performance while also having a waterproof, oil-proof and comfortable wearing experience. A layer of energy-absorbing layer 4 made of materials such as polyurethane foam or gel is arranged inside the toe 3 near the toes. When the toe 3 is impacted, this layer of material can absorb and dissipate energy through its own deformation, further reducing the impact force on the toes, improving the protection effect, and through the wear-resistant layer 5 provided on the sole 1, it can withstand the friction of the ground and the wear in various complex working environments, greatly extending the service life of the sole 1. At the same time, anti-slip patterns are designed at the bottom of the wear-resistant layer 5, thus providing reliable frictional force and reducing the risk of slipping, ensuring the walking safety of the wearer.
[0028] Embodiment 2: Different from Embodiment 1, this embodiment can facilitate the replacement of the wear-resistant layer 5 and extend the overall service life of the shoes. Specifically, refer to Figures 4-6 as shown. The upper surface of the wear-resistant layer 5 is fixedly provided with blocks 8 at equal intervals, the lower surface of the sole 1 is provided with slots at equal intervals, the inside of the sole 1 is provided with limiting plates 9 at equal intervals, and grooves are provided on the sides of the limiting plates 9. A first spring 10 is installed between the end of the limiting plate 9 and the inner wall of the sole 1. Both the front and rear sides inside the sole 1 are slidably connected with driving rods 7, and a second spring 11 is installed between the outer side of the driving rod 7 and the inner wall of the sole 1. The lower surface of the wear-resistant layer 5 is provided with anti-slip patterns. The blocks 8 and the slots are in a snap-fit connection. The limiting plates 9 are slidably arranged inside the sole 1, and the positions of the limiting plates 9 correspond to the limiting slots. The grooves on the limiting plates 9 are inclined. The end of the driving rod 7 is in contact with the inner wall of the groove. The driving rod 7 is arranged in a "C" shape, and the side of the driving rod 7 extends out of the outer surface of the sole 1.
[0029] When the wear-resistant layer 5 needs to be replaced, the user only needs to press the two driving rods 7, so that the ends of the driving rods 7 are inserted into the grooves on the limiting plates 9, prompting the limiting plates 9 to move and separate from the limiting slots, releasing the limitation on the blocks 8. Subsequently, the user pulls the wear-resistant layer 5 downward, making the blocks 8 separate from the slots, and the wear-resistant layer 5 can be removed from the sole 1. Then the user snaps the new wear-resistant layer 5 into the slots at the position of the sole 1 through the blocks 8 and releases the driving rods 7, so that the driving rods 7 reset under the elastic force of the second spring 11. At the same time, the driving rods 7 separate from the grooves, and then the limiting plates 9 reset under the elastic force of the first spring 10 and are inserted into the limiting slots on the blocks 8, which can limit the blocks 8 and complete the installation of the wear-resistant layer 5, thus facilitating the replacement of the wear-resistant layer 5 and extending the overall service life of the shoes.
[0030] Example 3: Unlike Example 2, this example utilizes a shock-absorbing layer 6 to effectively buffer the reaction force generated by the ground during walking, standing, or exercise, improving wearing comfort. See details... Figure 2 As shown, a shock-absorbing layer 6 is provided on the upper part of the inside of the sole 1, and the shock-absorbing layer 6 is made of EVA material.
[0031] By setting the shock-absorbing layer 6 inside the sole 1, the reaction force generated by the ground during walking, standing or exercise can be effectively buffered, reducing the vibration and impact on the feet, making the wearer feel more comfortable.
[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
