Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of security products, and in particular relates to a stab-proof liner and a stab-proof clothing. Background Art
[0002] The importance of stab-proof clothing to law enforcement officers cannot be ignored. Law enforcement officers often face various potential threats and dangers in their daily work, especially when dealing with violent crimes, maintaining public order, and conducting searches and arrests. In these tasks, law enforcement officers may encounter attackers with knives or sharp objects, or even premeditated attacks. In this case, stab-proof clothing, as a kind of protective equipment, is particularly important. As an important part of law enforcement equipment, stab-proof clothing not only improves the self-protection ability of law enforcement officers, but also enhances their ability to respond in dangerous environments. By providing effective protection, stab-proof clothing not only protects the lives of law enforcement officers, but also indirectly protects the safety of the public and social stability. Therefore, the importance of stab-proof clothing to law enforcement officers is self-evident and is an indispensable part of modern law enforcement work.
[0003] Although stab-proof clothing plays an important role in protecting the safety of law enforcement personnel, its disadvantages such as heavy weight, high price and complex maintenance have significantly limited its promotion and popularization in practice. Therefore, improving the design and materials of stab-proof clothing, reducing its weight and cost, and improving wearing comfort and convenience are important directions for the development of protective equipment in the future. Utility Model Content
[0004] In view of the problems existing in the prior art, the utility model provides a stab-proof liner and a stab-proof garment which solve the problems that the current stab-proof garments generally have the disadvantages of being heavy, thick and expensive.
[0005] The utility model is realized in this way: a stab-proof liner is characterized in that a stab-proof felt layer, a manganese steel layer, a stab-proof felt layer, a rubber-impregnated sheet, a stab-proof felt layer and an EVA layer are sequentially arranged on a stab-facing surface.
[0006] In the above technical scheme, preferably, the stab-proof liner is provided with a stab-proof felt layer, two 0.3 mm manganese steel layers, two stab-proof felt layers, two rubber-impregnated sheets, two stab-proof felt layers and a 5 mm EVA layer in sequence from the stab-facing surface.
[0007] In the above technical solution, preferably, the outer side of the stab-proof liner is covered with a waterproof cover.
[0008] The utility model proposes a stab-proof liner, which is a layered design formed by stab-proof felt as the main material, combined with manganese steel, and has many advantages of light weight, thin thickness and low cost. First of all, this stab-proof liner adopts a combination of stab-proof felt and manganese steel, which achieves a significant weight reduction effect in material selection and structural design. Stab-proof felt is a high-strength fiber material with excellent protective properties and relatively light weight. Manganese steel is known for its high hardness and durability. Through fine design and reasonable layout, the overall weight is effectively controlled, so that the stab-proof liner can provide strong protection while maintaining a low weight, reducing the burden on the wearer.
[0009] Secondly, the thin thickness of the stab-proof liner is particularly prominent. The layered design of the stab-proof felt allows it to maintain a relatively thin thickness without sacrificing protective performance. The high strength of manganese steel allows reliable stab protection at a relatively thin thickness. This design not only improves wearing comfort, but also maintains good flexibility, allowing law enforcement officers to be more flexible and at ease when performing their tasks without being restricted by heavy equipment.
[0010] In addition, the low cost of the stab-proof liner is also a major advantage. The material cost of stab-proof felt and manganese steel is relatively low, and the manufacturing process is relatively simple, which makes the overall production cost of the stab-proof liner controllable. Compared with traditional stab-proof clothing, this stab-proof liner has obvious advantages in terms of economy and is easier to mass produce and promote, so that more law enforcement personnel can be effectively protected.
[0011] In short, this stab-proof liner successfully achieves many advantages of light weight, thin thickness and low cost through clever material selection and innovative layered design. It not only improves the comfort and flexibility of the wearer, but also reduces the production and use costs, providing law enforcement personnel with an efficient and economical protective equipment.
[0012] The second purpose of the present invention is to provide a stab-proof clothing, which comprises a clothing body, and the above-mentioned stab-proof liner is installed inside the clothing body.
[0013] In the above technical solution, preferably, an interlayer is provided inside the clothing body, and the stab-proof liner is installed in the interlayer. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0017] In order to solve the disadvantages of the current stab-proof clothing, which are heavy, thick and expensive, the utility model provides a stab-proof liner and a stab-proof clothing, which have the advantages of light weight, thin thickness and low cost. In order to further illustrate the structure of the utility model, the detailed description is as follows in conjunction with the attached drawings:
[0018] Embodiment 1
[0019] See also Figure 1 and Figure 2 A stab-proof liner is provided with a stab-proof felt layer 1, a manganese steel layer 2, an stab-proof felt layer, a rubber-impregnated sheet 3, an stab-proof felt layer and an EVA layer 4 in order from the stab-facing surface.
[0020] Stab-proof felt is a high-performance material designed for personal and industrial protection. It is mainly used to prevent injuries caused by sharp objects. It is made of high-strength fibers such as aramid fiber, ultra-high molecular weight polyethylene fiber (UHMWPE) and glass fiber. After multi-layer stacking and high-temperature and high-pressure pressing, it forms a composite material with excellent puncture resistance. Stab-proof felt not only has extremely high strength and durability, but also has the characteristics of light weight, portability and good flexibility, which is convenient for making various protective clothing and equipment. It is widely used in security, military, police equipment and industrial safety protection and other fields. It can effectively resist the penetration of sharp objects such as knives and nails, and provide reliable safety protection.
[0021] Manganese steel is a high-strength steel with manganese as the main alloying element, usually containing about 12% to 14% manganese. It is known for its excellent wear resistance and toughness, and is widely used in situations that require high strength and impact resistance. Manganese steel has excellent hardness and wear resistance. When it is impacted, it will produce work hardening, which further increases its surface hardness and thus enhances its wear resistance.
[0022] Dipped sheets are high-performance composite materials that have been specially processed and are widely used in industry and manufacturing. They are made by immersing the substrate in a specific adhesive solution, which allows the adhesive solution to evenly penetrate and cover the surface of the substrate, forming a tough protective film. Dipped sheets are usually made of fiber fabrics, paper or other materials as the substrate. After being treated with adhesive, they have excellent waterproof, oil-proof, chemical corrosion and wear resistance. Due to its enhanced mechanical strength and durability, dipped sheets are often used in the manufacture of protective clothing, conveyor belts, seals, gaskets and gasketing materials for various industrial equipment. They are an important material choice to improve product life and performance.
[0023] EVA material, or ethylene-vinyl acetate copolymer, is a polymer material that is both soft and elastic. It has excellent impact resistance, chemical corrosion resistance and good transparency, while maintaining flexibility over a wide temperature range. EVA material is often used to make products such as soles, sports equipment, toys, packaging materials, and pads for medical equipment. It is highly favored for its lightweight, wear-resistant, waterproof and environmentally friendly properties.
