Description

Technical Field

[0001] This utility model relates to the field of bags and luggage, and in particular to a backpack. Background Technology

[0002] Most backpacks on the market today use zippers or elastic cords to seal the openings, thus protecting the items inside. While this provides good anti-theft protection, it is not convenient or quick for users to open the backpack. Summary of the Invention

[0003] The problem this utility model aims to solve is to provide a backpack that, while ensuring anti-theft protection, is easy for users to open.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a backpack, including a bag body and shoulder straps provided on the bag body. The bag body includes a front panel and a back panel. The top of the bag body has an opening, and the back panel has a limiting hole. One end of the shoulder strap is connected to the front panel, and the other end of the shoulder strap passes through the opening and the limiting hole to connect to the lower part of the bag body. The principle of this utility model is: the opening is controlled by adjusting the length of the shoulder strap above the opening, making the opening and closing simple and quick, thus optimizing the user experience.

[0005] As an improvement, the upper part of the package body is provided with a suture band, which is sewn onto the outer wall of the package body. The suture band includes a suture portion and a limiting portion. The suture band is sewn to the package body to form the suture portion, and the area of ​​the suture band not connected to the package body forms the limiting portion. A limiting hole is formed between the limiting portion and the package body.

[0006] As an improvement, the bag body is provided with two shoulder straps, and the two shoulder straps correspond to two limiting holes.

[0007] As an improvement, one end of the shoulder strap is sewn to the top of the front panel.

[0008] The beneficial effects of this utility model are as follows: The shoulder strap can be divided into a first part and a second part. The first part is the shoulder strap located above the opening, and the second part is the shoulder strap located on the outer side of the back panel. When closing the backpack: fix the second part and push the back panel towards the front panel. The opening decreases as the distance between the back panel and the front panel decreases until the opening is closed. At this time, the shoulder strap of the first part passes through the limiting hole to become the second part; or fix the back panel and pull the second part to close the opening and close the backpack. When opening the backpack: simply pry open the opening. At this time, the shoulder strap of the second part passes through the limiting hole to reach the top of the opening to become the first part. This utility model has a simple and quick opening and closing method, optimizing the user experience. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] like Figure 1 and Figure 2 As shown, a backpack includes a bag body 1 and two shoulder straps 2 attached to the bag body 1. The two shoulder straps 2 are symmetrical and adjustable in length. The bag body 1 includes a front panel 11 and a back panel 12. The top of the bag body 1 has an opening through which a user places items into the bag body 1. The top of the bag body 1 has a sewing strap 3, which is connected end to end and surrounds the outer wall of the bag body 1. The sewing strap 3 includes a sewing part 31 and a limiting part 32. The sewing strap 3 is sewn to the bag body 1 to form a sewing part. 31. The area where the stitching tape 3 is not connected to the bag body 1 forms a limiting part 32, and a certain gap is created between the limiting part 32 and the bag body 1, the gap forming a limiting hole 321; one end of the shoulder strap 2 is sewn to the top of the front panel 11, at this time to avoid the shoulder strap 2 affecting the internal capacity of the bag body 1 or the surface appearance of the front panel 11; the other end of the shoulder strap 2 first crosses the opening at the top of the bag body 1, then passes through the limiting hole 321 and connects to the lower part of the bag body 1; the two shoulder straps 2 correspond to two limiting holes 321. The manufacturer may also open a through hole in the upper area of ​​the rear panel 12, which serves as a limiting hole 321.

[0014] The working principle of this utility model is as follows: The shoulder strap 2 can be divided into a first part and a second part. The first part is the shoulder strap 2 located above the opening, and the second part is the shoulder strap 2 located on the outside of the back panel 12. When closing the backpack: fix the second part and push the back panel 12 towards the front panel 11. The opening decreases as the distance between the back panel 12 and the front panel 11 decreases until the opening is closed. At this time, the shoulder strap 2 of the first part passes through the limiting hole 321 to become the second part; or fix the back panel 12 and pull the second part to close the opening and close the backpack. When opening the backpack: simply pry open the opening. At this time, the shoulder strap 2 of the second part passes through the limiting hole 321 to reach the top of the opening and becomes the first part. This utility model has a simple and quick opening and closing method, optimizing the user experience.
