An adjusting buckle 11 is arranged on the tightening rope 9, and the adjusting buckle 11 is movably connected to the tightening rope 9. The tightening rope 9 can be tightened or loosened through the adjusting buckle 11. When the divider pad one 2, the divider pad two 3, the divider pad three 4 and the divider pad four 5 are rolled up, the tightening rope 9 can be tightened through the adjusting buckle 11 to limit and tightly wrap the rolled-up divider pad one 2, divider pad two 3, divider pad three 4 and divider pad four 5.

The rolled-up partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 can be used when the user uses the backpack to separate the user's back from the bag body 1, so as to ensure the air flow between the bag body 1 and the user's back, and improve the use experience of the backpack.

[0027] The working principle of the utility model: when using the backpack, the user carries the bag body 1 on the back through two bag belts, pulls the opening zipper 8 between the partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 and the bag body 1, and four independent closed spaces can be formed between the partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 and the bag body 1 for the user to store items. When the user's back contacts the bag body 1, the detachable cloth 6 on the partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 can be attached to the user's back to absorb part of the sweat on the user's back.

[0028] When the weather is hot and easy to sweat, the user can pull open the opening zipper 8 for connecting the bag body 1 and the corresponding partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 and ensure that the two sides of the opening zipper 8 are not completely pulled apart. At this time, the partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 are still connected to the bag body 1 respectively, then the four position partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 are rolled up to four sides, when the partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 are rolled up in place, the length of the tightening rope 9 is adjusted by the adjusting buckle 11 to wrap the rolled-up partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5, at the same time, the extension cloth strip 13 arranged on the side of the partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 close to the bag body 1 is pulled to the opposite position of the public buckle 14 and the female buckle 12, and the female buckle 12 and the public buckle 14 are pressed to be embedded to position the rolled-up partition pad one 2, partition pad two 3, partition pad three 4 and partition pad four 5 by the extension cloth strip 13, the public buckle 14 and the female buckle 12 (wherein the state diagram of the partition pad one 2 when rolling up is shown in Figure 6 .

[0029] The rolled-up partition pad 2, partition pad 3, partition pad 4 and partition pad 5 can make the bag body 1 not adhere to the back of the user when the user uses the backpack, so as to ensure the normal air flow between the back of the user and the bag body 1.
