The main zipper 104 is used to connect the front shell 102 and the rear shell 103 to facilitate the closure of the bag body 101 and prevent the items stored in the bag body 101 from falling. A rubber sleeve 105 is installed on the outer wall of the front shell 102. The rubber sleeve 105 is used to cooperate with the rear shell 103 to close the outer area of the main zipper 104, further improving the waterproof ability of the backpack and reducing the possibility of water penetrating into the backpack from the main zipper 104 area.
[0032] Specifically, a cushion 106 is bonded to the inner wall of the rear shell 103, and an anti-slip stripe structure is opened in the middle of the cushion 106. The arc-shaped edge of the side wall of the cushion 106 extends to the side wall of the rear shell 103. The cushion 106 is added in the middle of the rear shell 103 and contacts the back of the user, so that the back of the user is in better contact with the side wall of the rear shell 103, which can disperse the weight of the backpack and improve the comfort of using the backpack.
[0033] Furthermore, a shell 107 is bonded to the inside of the rear shell 103, and a main shaft 108 is connected to the inside of the shell 107 through a bearing. An upper shoulder strap 109 is wound in the middle of one group of main shafts 108, and a lower shoulder strap 110 is wound in the middle of another group of main shafts 108.
