Technical Field
[0001] This utility model relates to the technical field of backpack accessories, and in particular to a multifunctional layered storage student backpack. Background Technology
[0002] As we all know, backpacks are essential items for students' daily study and life. Their design needs to balance storage convenience, carrying comfort, and durability. Traditional backpacks are usually made of materials such as canvas and nylon, and their carrying function is achieved through the fixed connection between the shoulder straps and the bag body. Multifunctional layered storage student backpacks, on the other hand, further improve storage efficiency through partitioned compartments (such as main compartment, stationery compartment, and computer compartment). At the same time, in response to the diverse characteristics of student supplies, the addition of side pockets, external straps, and other functional structures has become the mainstream trend of current campus supplies.
[0003] Existing multi-functional layered storage student backpacks have been found to have shoulder straps that are mostly fixed to the bag body by sewing or rivets. During long-term daily use, the friction between the shoulder straps and the shoulders, as well as the weight of the items inside the bag, can cause fiber wear at the base of the shoulder straps (where they connect to the bag body). Once damaged, the entire backpack needs to be replaced, which reduces the convenience of the device and makes it less practical. Utility Model Content
