[0002] Existing waterproof packaging bags are mainly composed of a bag body, a bag cap, a waterproof zipper, and a shoulder strap, which are connected and fixed by sewing. The seams are sealed with sealant or sealing strips. During use, the bag body, bag cap, waterproof zipper, and shoulder strap are simultaneously subjected to the weight of the packaged product and the overload during carrying, which causes the seams to not be sealed and cannot meet the requirements for waterproof sealing during swimming.

[0003] Based on the aforementioned technical problems, CN205757943U discloses a portable sealed waterproof packaging bag, including a bag body and a bag bottom, and a waterproof zipper located on the bag body; the bag body, bag bottom, and waterproof zipper are bonded together with an adhesive; and a carrying strap device is provided on the bag body, which can be used for backpack carrying, single-shoulder carrying, and lifting. The carrying strap device includes fastening adjustment parts located at both ends of the bag body, the fastening adjustment parts including a bag body tightening strap and a backpack strap. The waterproof zipper is circumferentially located at one end of the bag body, and zipper covers are provided on both sides of the waterproof zipper, the zipper covers are bonded to the bag body with an adhesive, and the zipper covers are provided with leverage holes. Although this portable sealed waterproof packaging bag has a certain degree of sealing and waterproof performance, its sealing and waterproof performance when carrying items needs further improvement.

[0004] Existing patents have the following drawbacks:

[0005] (1) The device in the existing patent adopts a split structure, and the two adjacent structures are sewn together. However, the sewing method is not enough to achieve a seal. In rainy weather, there is a possibility of water leakage, which is detrimental to the items stored in the packaging bag.

[0006] (2) Existing patents mostly use adhesive bonding to fix the buckle to the back wall of the packaging bag, and then connect the strap directly to the buckle. The specific implementation method is to pass one end of the strap through the inner hole of the buckle, and then overlap it with the strap and sew it together. This achieves a fixed fixation, and the strap cannot be changed according to the user's personal preference. Utility Model Content
