[0007] As a large-capacity portable backpack of the utility model, preferably, a left limit strap is fixedly provided at the left end of the backpack body, and a right limit strap is fixed at the right end of the backpack body.

[0008] As a large-capacity portable backpack of the utility model, preferably, a limit strap buckle is installed on the left limit strap, and a limit strap clip is installed on the right limit strap.

[0009] As a large-capacity portable backpack of the present utility model, preferably, the limit belt buckle is matched with the limit belt clip, and the limit belt buckle is clamped inside the limit belt clip.

[0010] As a large-capacity portable backpack of the present utility model, preferably, left through holes and right through holes are respectively formed at the left and right ends of the bottom baffle.

[0011] As a large-capacity portable backpack of the present utility model, preferably, the left through hole is matched with the left limit belt, and the left limit belt passes through the left through hole, the right through hole is matched with the right limit belt, and the right limit belt passes through the right through hole.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] By the installation positions of the left limit belt on the limit belt buckle and the right limit belt on the limit belt clip, the length after the connection of the left limit belt and the right limit belt is controlled, and then the height of the bottom baffle moving downward from the bottom of the backpack body is adjusted, and then the telescopic length of the cloth tube is adjusted. Through the telescoping of the cloth tube by the bottom baffle, the backpack body is expanded, and different heights of the cloth tube are adjusted, and then different volumes of the backpack are adjusted, with strong flexibility and convenient for consumers to use.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] As Figure 1 shown;

[0028] A large-capacity portable backpack includes a backpack body 1 and a bottom baffle 2 provided at the bottom of the backpack body 1.

[0029] In this implementation scheme: CN 220675409 U, a large-capacity portable backpack, for details, refer to the publicly disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background art above, "Although this design realizes the function of expanding the backpack capacity, in the actual use process, the expansion of the backpack capacity can only be adjusted between the original capacity and the maximum capacity, and for the use requirements, it is impossible to adjust the capacity of different sizes according to the required capacity, and the flexibility is poor". In combination with the actual use, this problem is obviously a real and difficult problem to solve. In view of this, to solve this technical problem, a large-capacity portable backpack is provided here.

[0030] As Figures 1-4 shown in the figure;

[0031] Combined with the above content, a pair of shoulder straps 3 are provided on the backpack body 1, a handle 4 is provided at the top of the backpack body 1, and the bottom of the backpack body 1 is set as a bottom-opening structure.

[0032] In an optional embodiment, the backpack body 1 is connected to the bottom baffle 2 through a cloth tube 5, and the cloth tube 5 communicates with the backpack body 1.

[0033] In this embodiment: the backpack body 1 is expanded by the telescopic movement of the cloth tube 5 by the bottom baffle 2, and the height of the cloth tube 5 is adjusted, so as to adjust the different volumes of the backpack.

[0034] In an optional embodiment, a left limit strap 11 is fixedly provided at the left end of the backpack body 1, and a right limit strap 12 is fixed at the right end of the backpack body 1.

[0035] In an alternative embodiment, a limit belt buckle 13 is installed on the left limit belt 11, and a limit belt clip 14 is installed on the right limit belt 12.

[0036] In an alternative embodiment, the limit belt buckle 13 matches the limit belt clip 14, and the limit belt buckle 13 is snap-fitted inside the limit belt clip 14.

[0037] In an alternative embodiment, left through holes 21 and right through holes 22 are respectively formed at the left and right ends of the bottom baffle 2.

[0038] In an alternative embodiment, the left through hole 21 matches the left limit belt 11, and the left limit belt 11 passes through the inside of the left through hole 21. The right through hole 22 matches the right limit belt 12, and the right limit belt 12 passes through the inside of the right through hole 22.

[0039] In this embodiment: By the installation positions of the left limit belt 11 on the limit belt buckle 13 and the right limit belt 12 on the limit belt clip 14, the length after the connection of the left limit belt 11 and the right limit belt 12 is controlled.

[0040] The working principle of the present utility model:

[0041] By the installation positions of the left limit belt 11 on the limit belt buckle 13 and the right limit belt 12 on the limit belt clip 14, the length after the connection of the left limit belt 11 and the right limit belt 12 is controlled, thereby adjusting the height of the downward movement of the bottom baffle 2 from the bottom of the backpack body 1, thereby adjusting the telescopic length of the cloth cylinder 5. Through the telescoping of the cloth cylinder 5 by the bottom baffle 2, the backpack body 1 is expanded. By adjusting different heights of the cloth cylinder 5, different volumes of the backpack are adjusted, with strong flexibility and convenience for consumers to use.
