Description
Technical Field
[0001] The invention relates to the field of document bags, and in particular to a document bag with moisture-proof effect. Background Art
[0002] Document bags are used to store personal belongings or identity documents, information bags, and blank files. The styles are divided into buckle type and document sleeve type. Document bags are used to store personal belongings or identity documents, and are more durable and safer than document bags.
[0003] The existing document bag consists of a single-layer bag body and a handle. Although it has a simple structure and has good waterproof and wear-resistant effects, there are still other problems in use, such as poor portability and restraint effects. The document bag can be carried in two ways: held by a person or hung on a non-motor vehicle. When the document bag is hung, the handle is long and loose. When the non-motor vehicle shakes when passing through a bumpy road section, the paper documents in the bag are light in weight. When it is bumped and bounces and falls, it is easy to cause loss if the person does not find it in time. The safety is poor, and the documents in the bag cannot be flattened and limited. After the documents are placed in the bag, the space is relatively large, and the documents will slide in the bag. During the sliding process, the documents will be deformed and wrinkled due to bending and squeezing, which will have a certain impact on the quality of the documents and have low practicality. In order to solve the above-mentioned problems, we propose a document bag with a moisture-proof effect. Summary of the invention

After the water-shielding barrier layer is locked, the hand is placed on the top of the outer layer to press it. When the outer layer is pressed, it will not only reduce the internal free space to shrink, but also drive the second fixing plate to move toward the first fixing plate. After the top of the outer layer is pressed to fit the paper documents, the nut is grasped by hand and rotated. When the nut is rotated, it will fix the first fixing plate and the second fixing plate with the cooperation of the fixing screw, so that the documents in the bag can be limited and flattened, and the excess movable space in the bag can be removed to avoid the documents from being folded and wrinkled, thereby ensuring the storage quality of the documents in the bag. 2.
