The use principle of the utility model: the items in the storage cavity are pulled by the pull belt, which is convenient for users to take out the items in the storage cavity and optimizes the user experience.
[0005] As an improvement, a drawstring connected to the free end of the lifting strap is provided.
[0006] As an improvement, the lifting strap is a webbing.
[0007] As an improvement, a limiting belt is provided on the main bag body, both ends of the limiting belt are fixed on the main bag body, a movable opening is formed between the middle area of the limiting belt and the main bag body, and the pull rope passes through the movable opening from bottom to top.
[0008] As an improvement, an expansion bag connected to the side pocket is provided in the main bag body, and the expansion bag includes a baffle and a flexible fabric; one side of the baffle is sewn to the main bag body, and the other side of the baffle is connected to the main bag body through a quick connection mechanism; one end of the flexible fabric is connected to the main bag body, and the other end of the flexible fabric is connected to the baffle.
[0009] As an improvement, the baffle forms a cavity with the flexible fabric after being unfolded, and the cross-sectional shape of the cavity is a triangle.
[0010] As an improvement, the flexible fabric is a soft waterproof material.
[0011] As an improvement, the quick connection mechanism includes a first magnet disposed on the baffle and a second magnet disposed on the main package, and the first magnet and the second magnet attract each other.
[0012] The beneficial effects of the utility model are: water cups, umbrellas and other items in the side pockets can be taken out by pulling the drawstring, thereby optimizing the user experience; the expansion bag can be opened and closed, and will not occupy the internal volume of the main bag body when not in use. When in use, the volume of the accommodating cavity can be expanded, and it is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings of the specification:
[0020] like Figure 1 , 2As shown in Figure 3, a backpack with a pullable storage bag comprises a main bag body 1, and side pockets 2 for placing items such as water cups and umbrellas are arranged on both sides of the main bag body 1. A pull strap 22 for adjusting the height of the items in the bag is arranged in the side pocket 2. The pull strap 22 is a webbing, which can ensure a certain bearing strength, and the material is easy to obtain; the pull strap 22 is U-shaped, one end of the pull strap 22 is a fixed end, and the other end of the pull strap 22 is a free end. The fixed end of the pull strap 22 is fixed to the inner wall of the side pocket 2 by sewing, and a drawstring 21 is arranged on the free end of the pull strap 22, and the free end of the pull strap 22 extends out of the side pocket 2 through the drawstring 21. The user can make the water cup, umbrella and other items on the pull strap 22 extend out of the side pocket 2 by pulling the drawstring 21, which optimizes the user's experience. The main bag body 1 is provided with a limiting belt 23, both ends of which are fixed on the main bag body 1, and a movable opening 231 is formed between the middle area of the limiting belt 23 and the main bag body 1, and the drawstring 21 passes through the movable opening 231 from bottom to top; the movable opening 231 prevents the drawstring 21 from falling crookedly into the side pocket 2 under normal circumstances, and the user does not need to search for it in the side pocket 2 when using it.
[0021] like Figure 4 , 5 As shown, the main bag 1 is provided with an expansion bag 3 connected to the side bag 2, and the expansion bag 3 includes a baffle 31 and a flexible fabric; one side of the baffle 31 is sutured and connected to the main bag 1, and the baffle 31 can swing with the suture area as the axis; the other side of the baffle 31 is connected to the main bag 1 through a quick connection mechanism, and the quick connection mechanism includes a first magnet 32 arranged on the baffle 31 and a second magnet arranged in the main bag 1, and the first magnet 32 and the second magnet attract each other; the baffle 31 can close the expansion bag 3 by the magnetic attraction of the first magnet and the second magnet, and when in use, the expansion bag 3 is opened to expand the accommodating cavity. The flexible fabric is a soft waterproof material to prevent the water in the side bag 2 from entering the main bag 1 and wetting the items in the bag; one end of the flexible fabric is connected to the main bag 1, and the other end of the flexible fabric is connected to the baffle 31. After the baffle 31 is unfolded, it forms a cavity with the flexible fabric, and the cross-sectional shape of the cavity is a triangle.
[0022] The use principle of the utility model is: put objects such as water cups and umbrellas in the side pocket 2, lift the drawstring 21, so as to drag the objects on the pull strap 22 out of the side pocket 2, so that the user can take the objects in the side pocket 2 conveniently and optimize the user experience; the expansion bag 3 is closed by the magnetic effect. When in use, the baffle 31 is opened and the expansion bag 3 is unfolded, so that more objects can be placed in the side pocket 2, which is highly practical.
