Detailed Implementation Methods
[0031] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] Example 1
[0033] Please see Figures 2 to 4 As shown, this embodiment provides a backpack connector 100 connecting the bag body 200 and the shoulder strap 300. It includes a sheet-like plate 1 with a first wrapping hole 2 for the shoulder strap 300 to pass through and a second wrapping hole 3 for the webbing 400 to pass through. The first wrapping hole 2 and the second wrapping hole 3 are not connected and are set at an angle. The first wrapping hole 2 allows the shoulder strap 300 to pass directly through and adjusts its length. The second wrapping hole 3 allows the webbing 400 to pass directly through, after which the webbing 400 is sewn and fixed to the bag body 200. By setting the first wrapping hole 2 and the second wrapping hole 3 to be non-connected and at an angle, the shoulder strap 300 and the webbing 400 can pass through separately. This design is simple in structure, easy to install, avoids the multiple stitching required for traditional triangular fabric straps 400, and improves connection efficiency and consistency.
[0034] In this embodiment, the first wrapping hole 2 is a first strip-shaped wrapping hole; the second wrapping hole 3 is a second strip-shaped wrapping hole. Designing the wrapping hole as a strip shape facilitates the smooth passage and adjustment of the back strap 300 and webbing 400, avoids twisting or jamming, and improves the user experience and assembly efficiency.
[0035] In this embodiment, the included angle between the first wrapping hole 2 and the second wrapping hole 3 is an acute angle. Setting the included angle between the first wrapping hole 2 and the second wrapping hole 3 to an acute angle is more ergonomic, making the connection between the shoulder strap 300 and the bag body 200 more natural and improving carrying comfort.
[0036] In this embodiment, the included angle between the first wrapping hole 2 and the second wrapping hole 3 is 30-45°, which achieves the best balance between comfort and structural strength, and avoids stress concentration or inconvenience caused by excessively large or small angles.
[0037] In this embodiment, the sheet-like plate 1 includes a first plate surface 11 and a second plate surface 12. The first wrapping hole 2 has a first chamfer 21 formed at the opening of the first plate surface 11 and the second plate surface 12. The second wrapping hole 3 has a second chamfer 31 formed at the opening of the first plate surface 11 and the second plate surface 12. The chamfers at the openings of the first wrapping hole 2 and the second wrapping hole 3 reduce the wear of the strap during wearing, taking off and use, and extend the service life of the shoulder strap 300, webbing 400 and backpack connector 100.
[0038] In this embodiment, the sheet-like plate 1 is a plastic sheet-like plate 1. Made of plastic, the sheet-like plate 1 can be molded in one piece using injection molding or other methods, resulting in high consistency and low cost in mass production. The plastic sheet-like plate 1 replaces the traditional triangular fabric tape 400, avoiding deviations, wrinkles, or loose threads that easily occur during fabric cutting and sewing. The plastic sheet-like plate 1 provides higher tensile strength and abrasion resistance, avoiding the risk of cracking at seams and extending product lifespan. The plastic sheet-like plate 1 allows for a seamless, integrated design with smooth, burr-free edges, supporting various colors and surface treatments (such as matte and glossy), enhancing product texture. Preferably, the plastic is nylon, polypropylene, or reinforced engineering plastic.
[0039] In this embodiment, the plastic sheet 1 is an approximately trapezoidal plastic sheet 1. Designing the sheet 1 as an approximately trapezoidal shape makes it fit the structural shape of the bottom side of the backpack better, making the installation more stable and the appearance more harmonious. At the same time, it facilitates mold forming, improves production efficiency and product consistency.
[0040] In this embodiment, the sheet-like plate 1 has a third chamfer 13 formed at the edges of the first plate surface 11 and the second plate surface 12, which further reduces the sharpness of the edges and avoids scratches or wear to the user or the bag 200, shoulder strap 300 and webbing 400 during use, thereby improving safety and durability.
[0041] This utility model designs a simple and easy-to-manufacture plastic backpack connector 100 to replace the triangular fabric strap 400 used in traditional backpacks to connect the shoulder strap 300 and the bag body 200, and has the following overall beneficial effects:
[0042] 1. Improve production efficiency: Eliminate complex processes such as fabric cutting, multiple sewing, and turning, simplify the process flow, and reduce labor costs.
[0043] 2. Improve product consistency: Plastic backpack connectors 100 can be mass-produced using molds, ensuring precise dimensions and avoiding common issues such as deviations, wrinkles, and loose threads that are common in fabric sewing.
[0044] 3. Enhanced structural strength: The plastic backpack connector 100 (especially reinforced engineering plastic) has higher tensile strength and wear resistance, avoiding the risk of cracking at the seams.
[0045] 4. Optimize aesthetics and functionality: The plastic backpack connector supports a variety of colors and surface treatments, with a clean appearance and no rough edges. The angled design of the double strip holes is more ergonomic and improves the comfort of use.
[0046] Example 2
[0047] This embodiment provides a backpack, including a bag body 200, a shoulder strap 300, a webbing 400, and a backpack connector 100 as described in Embodiment 1; the upper end of the shoulder strap 300 is connected to the top of the bag body 200, the lower end of the shoulder strap 300 is wrapped around the first wrapping hole 2, one end of the webbing 400 is sewn to the bottom side of the bottom of the bag body 200, and the other end is wrapped around the second wrapping hole 3.
[0048] In this embodiment, a backpack uses a webbing 400 to pass through the second wrapping hole 3 of the backpack connector 100 and is sewn together with the bag body 200. Then, the shoulder strap 300 passes through the first wrapping hole 2 of the backpack connector 100. This means that the backpack connector 100 and the shoulder strap 300 no longer need to be sewn together, but can be directly passed through and wrapped. The shoulder strap 300 and the bag body 200 are connected by a single sewing. The backpack has the advantages of high production efficiency and good product quality.
[0049] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
