Description

Technical Field

[0001] This utility model relates to the field of schoolbag technology, and in particular to a durable schoolbag with a reinforced anti-breakage structure for the shoulder strap. Background Technology

[0002] In students' daily lives, schoolbags play a crucial role as essential tools for carrying various school supplies. The schoolbag straps are the key component connecting the schoolbag to the user, bearing the heavy responsibility of evenly distributing and stably supporting the weight of the schoolbag. With the popularization of education and the increasing academic burden on students, the number and weight of books, stationery, and other items carried in schoolbags have increased. According to relevant surveys, the average weight of schoolbags for primary and secondary school students has reached 4-6 kilograms, and the weight of some older students' schoolbags even exceeds 8 kilograms. Under such a heavy burden, extremely high demands are placed on the durability and breakage resistance of schoolbag straps.

[0003] In the existing technology, traditional schoolbag straps are mostly made of ordinary textile materials, such as cotton or ordinary chemical fibers. These materials can meet the needs of daily use. However, for students, schoolbags need to carry a lot of items every day, which causes the schoolbag straps to be subjected to great tension for a long time. In addition, the schoolbag straps will rub against the user's body during use, causing wear and tear. This can lead to the schoolbag straps breaking after frequent use, which will cause the items inside the schoolbag to fall out and damage them. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the backpack straps of the above-mentioned equipment break when subjected to large tensile forces because most backpack straps are made of ordinary textile materials. Therefore, this invention proposes a durable backpack with a reinforced anti-breakage structure for the straps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a durable backpack with a reinforced anti-breakage structure for the shoulder straps, including a backpack mechanism, wherein the outer wall of the backpack mechanism is provided with a shoulder strap mechanism;

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-4As shown, this utility model provides a durable backpack with a reinforced anti-breakage structure for the shoulder strap, including a backpack mechanism 1, and a shoulder strap mechanism 2 is provided on the outer wall of the backpack mechanism 1;

[0026] Backpack mechanism 1 includes a backpack body 11. Two first connecting boxes 12 are fixedly installed on one side of the outer wall of the backpack body 11. Each of the two first connecting boxes 12 is provided with multiple first rivets 121. Each of the two first connecting boxes 12 has an insertion slot 122 on one side of its outer wall. Two second connecting boxes 13 are fixedly installed on one side of the outer wall of the backpack body 11. Each of the two second connecting boxes 13 is provided with multiple second rivets 131. Each of the two second connecting boxes 13 has an installation slot 132 on one side of its outer wall. The shoulder strap mechanism 2 includes two first shoulder strap bodies 21 and two second shoulder strap bodies 24. Both the first shoulder strap bodies 21 and the second shoulder strap bodies 24 are composed of a core layer 25, two reinforcing layers 26, two buffer layers 27 and two surface layers 28. The first shoulder strap bodies 21 are installed inside the two insertion slots 122, and the first shoulder strap bodies 21, the first connecting box 12 and the backpack body 11 are fixed together by the first rivet 121 and high-strength nylon thread. The second shoulder strap bodies 24 are installed inside the two mounting slots 132, and the second shoulder strap bodies 24, the second connecting box 13 and the backpack body 11 are fixed together by the second rivet 131 and high-strength nylon thread.

[0027] The overall effect of Embodiment 1 is that when the backpack is subjected to a large amount of tension during use, the first connecting box 12, the first rivet 121, the second connecting box 13, the second rivet 131, and the high-strength nylon thread can fix the first shoulder strap body 21 and the second shoulder strap body 24 to the backpack. This prevents the shoulder straps from breaking or being damaged at the connection point when the backpack is loaded with heavy items, thereby extending the service life of the backpack and the backpack straps. Furthermore, under the action of the core layer 25 and the reinforcing layer 26, the core layer 25, which is made of high-strength nylon or polyester fiber woven tape, can provide strong load-bearing capacity for the backpack straps. The reinforcing layer 26, which is made of carbon fiber or Kevlar fiber cloth, enhances tensile strength and tear resistance, preventing the backpack straps from easily breaking or being damaged, and greatly improving the practicality of the straps.

[0028] Example 2: As Figures 2-4As shown, the outer wall of the core layer 25 is provided with two reinforcing layers 26, and the outer wall of each of the two reinforcing layers 26 is provided with a cushioning layer 27. The outer wall of each of the two cushioning layers 27 is provided with a surface layer 28. The core layer 25 is made of high-strength nylon or polyester fiber woven tape, and the thickness of the core layer 25 is 2-5mm. The two reinforcing layers 26 are both made of carbon fiber or Kevlar fiber cloth, and the thickness of the reinforcing layers 26 is 2-5mm. The two cushioning layers 27 are both made of three-dimensional mesh sponge or memory foam, and the thickness of the cushioning layers 27 is 4-7mm. The two surface layers 28 are both made of Oxford cloth or coated fabric, and the thickness of the surface layers 28 is 1-4mm. The outer wall of the backpack body 11 is provided with two mesh pockets 111. The outer walls of the two first shoulder strap bodies 21 are fixedly fitted with main buckles 22, and the outer walls of the two second shoulder strap bodies 24 are fixedly fitted with secondary buckles 23, and the outer walls of the secondary buckles 23 are movably inserted into the inside of the main buckles 22.

[0029] The overall effect of Embodiment 2 is that, during use, the mesh pocket 111 enhances the backpack's carrying capacity. The main buckle 22 and secondary buckle 23 facilitate faster disassembly and securing of the first shoulder strap body 21 and the second shoulder strap body 24, improving efficiency and ease of use. Furthermore, the cushioning layer 27, made of three-dimensional mesh sponge or memory foam, effectively disperses the pulling force exerted on the user's shoulders by the backpack's contents, enhancing comfort. The surface layer 28, made of Oxford cloth or coated fabric, significantly improves the shoulder straps' abrasion resistance and water penetration prevention, extending the lifespan of the backpack straps and further preventing breakage.

[0030] Working principle: When carrying heavy items in the backpack, the items inside exert significant tension on the backpack straps. At this time, the first connecting box 12, the first rivet 121, the second connecting box 13, the second rivet 131, and the high-strength nylon thread secure the first strap body 21 and the second strap body 24 to the backpack. This prevents the straps from breaking at the connection points due to excessive tension when the backpack is loaded with heavy items, thus extending the lifespan of the backpack and its straps. The first strap body 21 and the second strap body 24 consist of a core layer 25, a reinforcing layer 26, a cushioning layer 27, and a surface layer 28, from the innermost to the outermost layer. During use, the core layer 25 and the reinforcing layer 26 provide strong load-bearing capacity for the backpack straps. Since the core layer 25 is made of high-strength nylon or polyester fiber woven straps, it provides strong load-bearing capacity for the backpack straps. The reinforcing layer 26 is made of carbon fiber or Kevlar fiber cloth, which enhances tensile strength and tear resistance, preventing the backpack straps from easily breaking and damaging, and greatly improving the practicality of the straps. Under the action of the cushioning layer 27, which is made of three-dimensional mesh sponge or memory foam, the pulling force of the backpack items on the user's shoulders can be greatly dispersed, improving the comfort of use. Under the action of the surface layer 28, which is made of Oxford cloth or coated fabric, the abrasion resistance and water penetration resistance of the straps can be greatly improved, extending the service life of the backpack straps. When it is necessary to remove the backpack from the user, the first strap body 21 and the second strap body 24 can be quickly disassembled through the action of the main buckle 22 and the secondary buckle 23, making it more convenient to remove the backpack from the user.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
