Technical Field

[0001] This utility model belongs to the field of backpack technology, specifically relating to a backpack with a multifunctional accommodating cavity structure. Background Technology

[0002] Backpacks, as a convenient tool for carrying belongings, play an indispensable role in people's daily lives, work, study, and various outdoor activities. From students carrying schoolbags to commuting to office workers using backpacks, to outdoor sports enthusiasts relying on backpacks to carry their equipment, backpacks are ubiquitous. With the accelerating pace of life and the diversification of lifestyles, increasingly higher demands are being placed on the functionality and practicality of backpacks.

[0003] Traditional backpacks have ample internal space, but when carrying only a few items, the lack of effective securing and restraint causes these items to swing around freely as the user moves. This movement not only leads to items colliding with each other, increasing the risk of damage (e.g., fragile electronic products or glass items may break), but also makes the items inside the bag messy and disorganized. When a user needs to retrieve a particular item, they often have to spend a lot of time searching through the cluttered bag, greatly increasing the time spent organizing and causing considerable inconvenience.

The first functional package is fixedly connected to the front of the main package, and the two second functional packages are fixedly connected to the bottom of the left and right sides of the main package.

[0007] Furthermore, the main bag body has an opening connected to the main receiving cavity via a first zipper, the auxiliary bag body has an opening connected to the auxiliary receiving cavity via a second zipper, and a double shoulder strap is installed on the side of the main bag body away from the first functional bag.

[0008] Furthermore, the fixing plate has a cavity inside, and two vertical rods are fixedly connected between the upper and lower inner walls of the cavity. The fixing plate is fixedly connected to the inner wall on the side away from the shoulder straps.

[0009] Furthermore, the movable component includes a movable rod, a guide shaft, and a pull rope. The movable rod is slidably sleeved on the outer surface of the two vertical rods. The guide shaft is rotatably connected to the inner bottom wall of the cavity. One end of the pull rope is fixedly connected to the bottom end of the movable rod, and the other end of the pull rope passes around the guide shaft and extends to the outer side of the top of the fixed plate. A handle is fixedly connected to the top of the fixed plate.

[0023] This specific embodiment is a backpack with a multifunctional accommodating cavity structure, and its structural schematic diagram is shown below. Figures 1-7 As shown, the package includes a main package 1, a main receiving cavity 2 inside the main package 1, an auxiliary package 3 outside the main package 1, an auxiliary receiving cavity 4 inside the auxiliary package 3, a limiting component 5 inside the main receiving cavity 2, the limiting component 5 including a fixed plate 6 fixedly connected along the height direction of the main receiving cavity 2, a movable part 7 adjustablely provided inside the fixed plate 6, a limiting band 8 fixedly connected to the movable part 7, a female buckle 9 fixedly connected to the other end of the limiting band 8, and a male buckle 10 corresponding to the female buckle 9 fixedly connected to the inner wall of the main receiving cavity 2, the male buckle 10 being located at one-third of the inner wall of the main receiving cavity 2.

[0024] like Figure 1As shown: In this embodiment, the auxiliary bag 3 includes a first functional bag 301 and two second functional bags 302. The first functional bag 301 is fixedly connected to the front of the main bag 1, and the two second functional bags 302 are fixedly connected to the bottom of the left and right sides of the main bag 1. By setting the first functional bag 301 and the two second functional bags 302 on the outside of the main bag 1, the classification and storage of items can be assisted. These functional bags can be specially designed according to the type and purpose of the items, and are specifically used to place water cups, store umbrellas, store small items, etc., so that the items can be stored more orderly and convenient for users to quickly access them.

[0025] like Figure 1 As shown: In this embodiment, the main bag body 1 has an opening communicating with the main receiving cavity 2 via a first zipper 101, and the auxiliary bag body 3 has an opening communicating with the auxiliary receiving cavity 4 via a second zipper 303. A double shoulder strap 102 is installed on the side of the main bag body 1 away from the first functional bag 301. Items in the main receiving cavity 2 can be quickly accessed via the first zipper 101, and items in the auxiliary receiving cavity 4 can be quickly accessed via the second zipper 303.

[0026] In order to reduce the overall weight, such as Figure 2 and Figure 6 As shown: In this embodiment, a cavity 601 is provided inside the fixing plate 6. Two vertical rods 602 are fixedly connected between the upper and lower inner walls of the cavity 601. The fixing plate 6 is fixedly connected to the inner wall on the side away from the shoulder strap 102. The fixing plate 6 is made of lightweight plastic, and the shoulder strap 102 is an existing adjustable shoulder strap structure.

[0027] like Figure 3 and Figure 6 As shown: In this embodiment, the movable component 7 includes a movable rod 701, a guide shaft 702, and a pull rope 703. The movable rod 701 is slidably sleeved on the outer surface of the two vertical rods 602. The guide shaft 702 is rotatably connected to the inner bottom wall of the cavity 601. One end of the pull rope 703 is fixedly connected to the bottom end of the movable rod 701, and the other end of the pull rope 703 passes around the guide shaft 702 and extends to the outer side of the top of the fixed plate 6. A handle 704 is fixedly connected to the top of the fixed plate 6. The handle 704 is used to bind the pull rope 703. After the item is put into the main receiving cavity 2 of the main package 1, the pull rope 703 is pulled to move upward. At this time, the pull rope 703 causes the movable rod 701 to slide downward along the vertical rod 602 through the guide shaft 702. During the movement, the movable rod 701 can drive the left end of the connecting rope 801 and the limiting band 8 to move downward, thereby fixing the put-in item through the limiting band 8.

[0028] To prevent the pull rope 703 from coming off, such as Figure 6 and Figure 7As shown: In this embodiment, the top of the fixing plate 6 is provided with a circular hole corresponding to the pull rope 703. The top of the pull rope 703 is fixedly connected to a limiting block 705. The limiting block 705 is larger than the size of the circular hole and will not fall into the interior of the fixing plate 6.

[0029] like Figure 7 and Figure 8 As shown: In this embodiment, two connecting ropes 801 are fixedly connected to one end of the limiting band 8 near the fixing plate 6. Two elongated holes 802 are opened on the right side of the fixing plate 6. The other end of the connecting rope 801 passes through the elongated holes 802 and is fixedly connected to the movable rod 701. The limiting band 8 is an elastic mesh belt, generally made of elastic rubber or nylon material. There are two female buckles 9. The two female buckles 9 are fixedly connected to the two ends of the right side of the limiting band 8. The limiting band 8 can be fixed by the two female buckles 9 to firmly prevent it from falling off.

[0030] Working principle: When in use, separate the limiting strap 8 from the female buckle 9 and male buckle 10, then put the item into the main receiving cavity 2 of the main package 1, and then fasten the female buckle 9 and male buckle 10 of the limiting strap 8 together for initial fixation. Then pull the pull rope 703 to move it upward. At this time, the pull rope 703 causes the movable rod 701 to slide downward along the vertical rod 602 through the guide shaft 702. During the movement, the movable rod 701 can drive the connecting rope 801 and the left end of the limiting strap 8 to move downward. Since the right side of the limiting strap 8 is fixed, the pulling rope 703 can fix the inserted item by the limiting strap 8. Then tie the pull rope 703 to the handle 704 to fix it. In this way, the elastic contraction force of the limiting strap 8 is used to tightly bind the item in a specific position, preventing the item from shaking in the main receiving cavity 2 and effectively avoiding the item from being messy or damaged due to shaking.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
