[0023] Example

[0024] Please see Figures 1-4 This embodiment provides a backpack with a weight-reducing function, including a backpack body 1. The top of the backpack body 1 is provided with a rubber handle 2 and a webbing handle 3, both of which serve to facilitate carrying the backpack and can be used to lift the backpack. The rubber handle 2 is located in front of the webbing handle 3, which is made of nylon and leather film. The front and sides of the backpack body 1 are made of waterproof fabric 4, which makes the backpack waterproof and protects the items inside the backpack. The middle of the front of the backpack body 1 is provided with a middle storage pocket 5, and the lower side of the middle storage pocket 5 is provided with a bottom storage pocket 6. Waterproof zippers 7 are installed at the entrances of both the middle storage pocket 5 and the bottom storage pocket 6. The waterproof zippers 7 serve to seal and also have a certain waterproof effect, preventing external water from entering the backpack through the seal.

[0025] The backpack body 1 is also equipped with an expansion layer 8 around its perimeter. An expansion layer zipper 9 is installed on the outside of the expansion layer 8. When the expansion layer zipper 9 is opened, the expansion layer 8 can be expanded when the backpack is carrying more items, thereby increasing the internal volume of the backpack. When not in use, the expansion layer zipper 9 can be closed. At the same time, two pairs of buckles 10 are symmetrically connected on the front and back of the backpack body 1. After the buckles 10 are connected, the thickness between the front and back of the backpack can be reduced. At the same time, when it is filled with items, the buckles 10 can also play a certain role in limiting the items and preventing them from shaking inside the backpack. A customs lock 11 is also installed on one side of the backpack body 1, which can increase security.

[0026] The back of the backpack body 1 is provided with a breathable mesh layer 12, and a pull rod webbing 13 is provided below the breathable mesh layer 12. A bottom storage pocket 14 is provided below the pull rod webbing 13. When the user carries the backpack, the breathable mesh layer 12 can achieve the function of ventilation and improve the user experience, while the bottom storage pocket 14 increases the storage space.

[0027] The back of the backpack body 1 is provided with two symmetrical shoulder straps 15. The shoulder straps 15 have the function of cushioning and reducing the burden, which can reduce pressure when the user uses it. The shoulder straps 15 include an upper shoulder strap 151 and a lower shoulder strap 152. One end of the upper shoulder strap 151 is connected to the backpack body 1, and a shoulder strap webbing 153 is installed on it. The bottom of the shoulder strap webbing 153 is inserted into the webbing adjustment buckle 154, and the webbing adjustment buckle 154 is installed at the end of the lower shoulder strap 152. The other end of the lower shoulder strap 152 is fixed to the backpack body 1. The length of the shoulder strap webbing 153 can be adjusted by the webbing adjustment buckle 154, thereby realizing the length adjustment of the entire shoulder strap 15 to adapt to different users.

[0028] A breathable mesh layer 12 is also provided on the inside of the upper shoulder strap 151 to improve the comfort of the shoulder strap 15 when carrying it. A chest strap 155 is provided between the two shoulder strap webbing 153 on the left and right sides. The chest strap 155 has an openable chest buckle in the middle, and loop buckles are provided at both ends of the chest strap 155. These loops are fitted onto the shoulder strap webbing 153 to adjust the position of the chest strap 155 on the shoulder strap webbing 153. The chest buckle can separate the chest strap 155, and then after the backpack is worn, it can be fastened in front of the chest to increase stability.

[0029] The upper shoulder strap 151 includes a main fabric 1515 and a strap body 1511. The main fabric 1515 is spliced ​​on the back of the backpack body 1, and two vertical webbing straps 1513 are symmetrically arranged on it. The upper and lower ends of the vertical webbing straps 1513 are fixed to the main fabric 1515, and the horizontal webbing strap 1514 is fixed to the back of the strap body 1511. The vertical webbing straps 1513 are fixed on both sides of the horizontal webbing strap 1514 by bar-tying through the width of the vertical webbing straps 1513. The vertical webbing straps 1513 can slide on the horizontal webbing strap 1514. The horizontal webbing strap 1514 and the vertical webbing strap 1513 form a cross structure.

[0030] A horizontal webbing 1514 is fixed to the strap body 1511. The bottom of the strap body 1511 is provided with a weight-reducing strap 1512. The bottom of the weight-reducing strap 1512 is fixed to the back of the backpack body 1. The innermost side of the weight-reducing strap 1512 is set as an inner webbing 15121, which is a conventional webbing material. On the outside of the inner webbing 15121, there are multiple layers of upper elastic webbing 15122, which are elastic. Furthermore, the inner webbing 15121 is longer than the upper elastic webbing 15122. In this way, when the upper shoulder strap 151 is subjected to force, the upper elastic webbing 15122 can be pulled, which plays a buffering role. That is, the inner webbing 15121 leaves a margin for the stretching of the upper elastic webbing 15122. The extra length of the inner webbing 15121 is the longest length of the upper elastic webbing 15122.

[0031] The lower shoulder strap 152 has two leather patch loops 1523. Between the two leather patch loops 1523, there is a lower elastic webbing 1521 and an outer webbing 1522. There are multiple lower elastic webbing 1521, which are located inside the outer webbing 1522. Similarly, the outer webbing 1522 also has a margin. The margin of the outer webbing 1522 is the longest length of the lower elastic webbing 1521, so that the lower elastic webbing 1521 can be stretched. The total length of the inner webbing 15121 and the outer webbing 1522 is the total length of the upper elastic webbing 15122 and the lower elastic webbing 1521 when stretched, respectively.

[0032] This invention achieves a load-bearing function in the upper part of the shoulder strap 15 by combining vertical webbing 1513, horizontal webbing 1514, and a fixed-length inner webbing 15121 with multiple upper elastic webbing 15122. Simultaneously, in the lower part of the shoulder strap 15, multiple lower elastic webbing 1521 are combined with outer webbing 1522 to further reduce the load. Furthermore, in the upper part, horizontal webbing 1514 and vertical webbing 1513 form a cross-webbing structure, maximizing the function of the elastic webbing. This combination of upper and lower elastic structures achieves a load-bearing effect, allowing users to cushion and reduce the load when carrying heavy loads through elastic stretching, providing comfortable travel and relieving shoulder pressure.
