[0030] 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.
[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an embossed woven shoulder bag with an anti-deformation structure, including a carbon fiber composite strip 1. The carbon fiber composite strip 1 is existing technology. The carbon fiber composite strip 1 can support the overall shape, thereby preventing it from being squeezed by external forces and thus deforming. The surface of the carbon fiber composite strip 1 is fixedly connected to the bag body 3. The top of the carbon fiber composite strip 1 is fixedly connected to the handle 2. The surface of the handle 2 is detachably mounted with a shoulder strap 4. Positioning buckles 5 are fixedly connected to both sides of the shoulder strap 4. Positioning grooves are opened at the ends of both sides of the shoulder strap 4. The outer wall of the positioning buckle 5 fits the inner wall of the positioning groove. The two sides of the shoulder strap 4 pass through the handle 2 respectively and are folded, so that the positioning groove at the end of the shoulder strap 4 can be positioned and pressed tightly with the positioning buckle 5 on the surface, thereby increasing the overall aesthetics. The outer wall of the shoulder strap 4 contacts the limiting ring 6. By setting the limiting ring 6, the shoulder strap 4 is bound and pressed tightly after being folded, preventing the positioning groove of the shoulder strap 4 from loosening after being positioned and pressed with the positioning buckle 5.
[0032] Reference Figure 2 - Figure 4The bag body 3 includes an inner layer 31. A textured layer 32 is fixedly connected to the bottom of the outer wall of the inner layer 31. The textured layer 32 is made of bamboo fiber embossed material, which not only gives the bag a unique and beautiful appearance, but also increases surface friction for easy handling. After vacuum penetration of a beeswax mixture solution, the bamboo fiber has natural antibacterial properties, which can inhibit bacterial growth and reduce odor. At the same time, the surface friction coefficient is 0.65, which ensures a comfortable feel and prevents items from slipping to a certain extent. A functional layer 33 is fixedly connected to the bottom of the outer wall of the textured layer 32. A surface protective layer 34 is fixedly connected to the bottom of the outer wall of the functional layer 33. The surface protective layer 34 is made of beeswax. Natural white beeswax and palm wax are mixed in a 7:3 ratio and vacuum-penetrated into the leather surface at 60℃ / -0.1MPa, which enhances wear resistance and reduces the friction coefficient by 40%, reducing damage to the leather surface from daily friction. It also has self-healing properties, with minor scratches automatically healing within 48 hours, maintaining the integrity of the bag's appearance and extending its service life.
[0033] Reference Figure 3 and Figure 5 The inner layer 31 also includes a base layer 311, which is made of Kevlar blended base. Kevlar fiber has the characteristics of high strength and high toughness. When blended with nylon, it can effectively enhance the deformation resistance of the entire base while providing basic tear resistance. The plain weave and high warp and weft density make the fabric structure tight and not easily deformed under external force, providing stable support for the package. The bottom of the outer wall of the base layer 311 is fixedly connected to the reinforcing layer 312. The reinforcing layer 312 is designed with the aramid fiber itself having extremely high strength. The 0.3mm thickness of Nomex III A aramid nonwoven fabric significantly improves the single-point puncture resistance by 400%, effectively preventing damage to this area due to excessive force or puncture by sharp objects, and enhancing the reliability and durability of key parts of the package. The reinforcing layer 312 is composed of two groups of aramid fibers, one of which is mesh-like from top to bottom, and the other is curved. The combination of mesh and curved shape makes the overall strength higher, and can effectively protect the whole from damage when subjected to external pulling force.
[0034] Reference Figure 4 The functional layer 33 also includes a protective layer 331, which is made of a nano-polyurethane film. This nano-polyurethane film is uniformly sprayed and UV-cured onto the outside of the bamboo fiber embossed layer. The 15μm thick water-based PU nano-coating provides excellent waterproof performance, withstanding water pressure up to 8000mm, effectively preventing rainwater and splashes from penetrating the interior of the package; its moisture permeability is 5000g / m³. 2The 24hr breathability ensures excellent ventilation, preventing moisture buildup inside the bag. A QUV accelerated aging test shows a yellowing index of <2 after 500 hours, demonstrating excellent anti-aging capabilities and maintaining the bag's vibrant color for a long time. A silicone anti-slip dot matrix layer 332 is fixedly connected to the bottom of the outer wall of the protective layer 331. This layer is formed on the surface of the nano-polyurethane film through laser engraving and dispensing printing. The food-grade liquid silicone has a Shore hardness of 50A, with 2mm diameter hemispherical protrusions spaced 5mm apart and covering 35% of the surface. In a humid environment, it can increase the coefficient of friction to 1.2, greatly enhancing the anti-slip effect of the bag surface. Whether carried by hand or over the shoulder, it ensures the bag's stability and prevents it from slipping.
[0035] Working principle: This embossed woven shoulder bag with an anti-deformation structure uses carbon fiber composite strip 1 as the skeleton to support the overall shape and avoid deformation due to external pressure. The top of the carbon fiber composite strip 1 is fixed with a handle 2, and a shoulder strap 4 can be detachably installed at the handle 2. There are positioning buckles 5 on both sides of the shoulder strap 4 and positioning grooves at the end. After passing through the handle 2 and folding, the positioning buckles 5 fit into the positioning grooves and are pressed tightly. The folded part is then restrained by the limiting ring 6 to prevent loosening.
[0036] The bag body 3 consists of an inner layer 31, a textured layer 32, a functional layer 33, and a surface protective layer 34. The base layer 311 of the inner layer 31 is a Kevlar blended base with a plain weave and high warp and weft density, which enhances tear resistance and deformation resistance. The reinforcing layer 312 uses aramid fiber non-woven fabric to improve single-point puncture resistance. The textured layer 32 is a bamboo fiber embossed layer, which gives it a beautiful appearance, increases friction, and has natural antibacterial properties. In the functional layer 33, the protective layer 331 is a nano-polyurethane film, which is waterproof, breathable, and anti-aging. The silicone anti-slip dot matrix layer 332 is made of food-grade liquid silicone, which enhances the anti-slip effect. The surface protective layer 34 is made of beeswax infiltrated into the leather surface in a specific ratio, which is wear-resistant and has self-healing properties. All parts work together to achieve the bag's functions of deformation resistance, wear resistance, waterproofing, and anti-slip.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
