[0024] 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 making creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a large - capacity document bag, including a front plate 1 and a back plate 2. The front plate 1 and the back plate 2 are in a separated structure. By moving the front plate 1, the front plate 1 and the back plate 2 can be separated. A folding page 3 is provided between the front plate 1 and the back plate 2. After the front plate 1 and the back plate 2 are separated, the folding page 3 is in an open state so as to put the required documents into the folding page 3. The material of the folding page 3 is a waterproof material. The waterproof folding page 3 will not be penetrated by water, so it can prevent the internal documents from contacting water, thus playing a certain moisture - proof role. A magnetic strip 12 is built into the front plate 1, and an iron sheet 14 that cooperates with the magnetic strip 12 is provided on one side of the folding page 3. Since the front plate 1 is fixed by the cooperation of the magnetic strip 12 inside it and the iron sheet 14 on the folding page 3, when loading more documents into the folding page 3, the front plate 1 can be removed to obtain a larger storage space.

[0026] Please refer to Figures 1 to 3 , one side of the back plate 2 is fixed with an elastic band 4. The end face structure of the elastic band 4 is in a U - shaped structure. A first rivet 8 for fixing is provided at one end of the elastic band 4 close to the back plate 2. At least three elastic bands 4 are arranged in a central symmetry along the center point of the back plate 2. The three elastic bands 4 in central symmetry can make the elastic band 4 receive force more evenly and can fix the front plate 1, the back plate 2 and the folding page 3 more stably. The elastic band 4 at the bottom can also support the folding page 3 to play a protective role. A magic tape 5 is provided on the elastic band 4, and the magic tape 5 on the elastic band 4 is attached to the sub - sticker 11 on the front plate 1. By tightening the folding page 3 between the front plate 1 and the back plate 2 through the provided elastic band 4, the documents in the folding page 3 are fixed to prevent the documents from sliding and slipping out.

[0027] Please refer to Figures 1 to 3, a cover plate 13 is provided at the top of the back plate 2. The cover plate 13 and the back plate 2 are of an integral structure. The cover plate 13 and the front plate 1 are provided with corresponding connecting devices. The connecting device includes a plastic sheet 6. The plastic sheet 6 is arranged on the front plate 1. A second rivet 10 for fixing the plastic sheet 6 is arranged on the front plate 1. One end of the cover plate 13 is provided with a cord 7, and a ring 9 is arranged at the end of the cord 7. By folding the cover plate 13, the cover plate 13 can cover and seal the opening of the folding hinge 3. Through the cooperation of the cord 7 and the plastic sheet 6, the cover plate 13 can be fixed, ensuring the stability of the seal and preventing the separation of the front plate 1 and the cover plate 13. The connection between the cover plate 13 and the back plate 2 can rotate. The cover plate 13 is foldable and needs to fit with the front plate 1 after folding. The distance between the front plate 1 and the back plate 2 will change, and the opening of the folding hinge 3 will also change. Because the cover plate 13 is foldable, after the opening of the folding hinge 3 changes, the cover plate 13 can perfectly seal the folding hinge 3.

[0028] Please refer to Figures 1 to 7 , the end face structures of the front plate 1 and the back plate 2 are the same. The same structure can ensure stable placement during storage, not easy to tilt, and can also ensure that the cover plate 13 better seals the folding hinge 3. The materials of the front plate 1 and the back plate 2 are both plastic materials. The plastic front plate 1 and back plate 2 have good wear resistance and waterproofness, effectively preventing the document bag from being damaged and extending the service life.

[0029] The working principle and usage process of the present utility model: When there are documents inside the folding hinge 3, since elastic bands 4 for clamping the document bag are provided at both ends and the bottom of the back plate 2, the elastic bands 4 can be stretched and the magic tape 5 provided at its end can be attached to the sub-patch 11 provided on the front plate 1, so that the front plate 1 and the back plate 2 clamp the documents to prevent the documents from sliding and slipping out inside the document bag;

[0030] According to the distance between the front plate 1 and the back plate 2, fold the cover plate 13 so that it can close the folding hinge 3 and wind the cord 7 at its top under the plastic sheet 6 fixed by the second rivet 10, thereby fixing the cover plate 13;

[0031] During use, the front plate 1 of the document bag can be separated from the folding hinge 3, and the elastic band 4 itself has elasticity and can be stretched. Therefore, when there are more documents, the distance between the front plate 1 and the back plate 2 can be increased through the elastic band 4 to place more documents.

[0032] Finally, it should be noted that the above are only preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
