Detailed implementation manners
[0022] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.
[0023] Referring to Figures 1-2 , the present utility model provides a knitted waterproof cross-body bag, including a knitted bag body 1, a three-dimensional pleated decorative pattern 2 is arranged on the outer surface of the knitted bag body 1, and a storage bag 3 is arranged inside the knitted bag body 1;
[0024] The knitted bag body 1 is composed of a composite of an outer high-performance waterproof and breathable film 11, an intermediate reinforced knitted layer 12, and an inner functional fiber layer 13. The outer high-performance waterproof and breathable film 11 is composed of a composite of a polytetrafluoroethylene film with a microporous structure and a polyurethane coating;
[0025] The surfaces of both the three-dimensional pleated decorative pattern 2 and the storage bag 3 are coated with a waterproof coating, and the waterproof coating is a polyurethane PU coating.
[0026] Referring to Figure 3 , the intermediate reinforced knitted layer 12 is knitted by a three-dimensional knitting technique. This structure not only enhances the tear resistance and wear resistance of the fabric but also endows it with good elastic recovery ability.
[0027] Referring to Figure 3 , the inner functional fiber layer 13 evenly distributes nano silver ions on the fiber surface through an electrospinning technique, so that the inner functional fiber layer 13 has a good antibacterial protection effect. When the cross-body bag stores clean items such as tissues, food, or personal items, it can provide a strong antibacterial protection effect.
[0028] Referring to Figures 2-3 , the surfaces of both the outer high-performance waterproof and breathable film 11 and the waterproof coating of the three-dimensional pleated decorative pattern 2 are covered with an anti-ultraviolet aging coating to enhance the weather resistance of the knitted bag body 1 and the fabric of the three-dimensional pleated decorative pattern 2.
[0029] Referring to Figure 3 , the outer high-performance waterproof and breathable film 11, the intermediate reinforced knitted layer 12, and the inner functional fiber layer 13 are all tightly connected by a combination of an environment-friendly hot melt adhesive and a high-frequency hot pressing technique. After the layers are tightly connected, they have relatively good washability, ensuring that the product is not easily detached or damaged during use and has good environmental performance.
[0030] Referring to Figure 2 、4 5. The storage bag 3 is provided with a plurality of compartments, and a wire rack 4 is installed inside the storage bag 3. The wire rack 4 includes a mounting plate 41. The mounting plate 41 is provided with symmetrical notches on the front side, and wire winding arms 42 are installed in the notches. Both ends of the two wire winding arms 42 are provided with V-shaped wire clamping grooves 421. The messenger bag places items through the storage bag 3, and the compartments are provided to facilitate the classification and placement of the placed items, so that the items are more regular. However, it is difficult to arrange special items such as data cables, headphones and other wire items in an orderly manner. In order to avoid knotting when storing wire items, the wire rack 4 is provided to store the wire items. When in use, the wire ends are inserted into the V-shaped wire clamping grooves 421 to achieve a fixing effect. Then, the wire items can be wound around the two wire winding arms 42 to achieve a regular storage effect of the wire items, thereby improving the practicality of the messenger bag.
[0031] Reference Figure 4 , 5 The top and bottom of the winding arm 42 are both provided with a convex column 43, and the inner wall of the slot of the mounting plate 41 is provided with two rotating holes. The two convex columns 43 are movably sleeved in the two rotating holes respectively. When the wire rack 4 is not used to store wire items, the two winding arms 42 are convex outward and occupy the storage space of the messenger bag. By setting the convex column 43 and the rotating hole design in the slot, the winding arm 42 has a flipping effect, so that the two winding arms 42 can be flipped outward and hidden in the slot of the mounting plate 41, thereby avoiding the problem of the winding arm 42 occupying the storage space.
[0032] Reference Figure 4 , 5 The fixed end of the protruding column 43 is transmission-connected to the inner wall of the slot of the mounting plate 41 through a torsion spring 44. The front side of the mounting plate 41 is movably connected with a knob 45 located outside the two slots. The side wall of the knob 45 is fixedly connected with a convex plate 46. By arranging the torsion spring 44, the winding arm 42 can automatically flip over to present an outward convex effect under the effect of its torque. When the winding arm 42 is hidden in the slot, the convex plate 46 is driven to flip toward the slot by rotating the knob 45, so that the convex plate 46 can cover the winding arm 42 in the slot, thereby locking the winding arm 42 in the slot.
