[0027] Refer to Figures 1-5, A turnover bag with adjustable internal storage space, comprising: a main bag body 1 and a movable bag body 2. A plurality of mounting grooves are longitudinally and equidistantly formed at both the front and rear ends of the movable bag body 2. A first threaded ring 5 is arranged in each mounting groove. Two jacks 6 are provided at both ends of the main bag body 1. A first bolt 7 can be connected in the jacks 6. The main bag body 1 and the movable bag body 2 can adopt common materials for turnover bags on the market, such as canvas, polyester fiber, etc. In terms of design, the internal spaces of the main bag body 1 and the movable bag body 2 can be communicated. The main reason is that the bottom of the movable bag body 2 is designed with a hollow and can be fitted and inserted into the main bag body 1. The first threaded rings 5 in the mounting grooves at both the front and rear ends of the movable bag body 2 can be used as positioning points. When the movable bag body 2 is longitudinally moved, after the jacks 6 at both ends of the main bag body 1 are aligned with the corresponding first threaded rings 5, the position of the movable bag body 2 can be fixed by connecting the first bolt 7 to the inside of the corresponding first threaded ring 5. The operation is simple, and the purpose of adjusting the internal storage space is achieved by increasing the longitudinal space.

[0028] At the same time, when the movable bag body 2 is longitudinally moved, the movable bag body 2 can pull the movable belts 13 fixed at both the front and rear ends to move. The movable belts 13 are all inserted into the inner grooves of the elastic belts 4 and then move in the inner grooves. After the position of the movable bag body 2 is fixed, the position of the movable belts 13 can be fixed at this time.

[0029] Furthermore, when the movable belts 13 are fixed, first, it is necessary to ensure that the second threaded rings 14 on the surfaces of the movable belts 13 are aligned with the second bolts 15 connected to the surfaces of the elastic belts 4, and then the second bolts 15 can be connected to the corresponding second threaded rings 14 to complete the fixing of the movable belts 13.

[0030] And, the second threaded rings 14 are used as positioning points. When the second threaded rings 14 and the second bolts 15 cannot be just aligned, the elastic belts 4 can be pulled to align the second bolts 15 with the second threaded rings 14.

[0031] Specifically, after items are placed inside the turnover bag, a sealing sleeve 3 can be connected above. A first hook surface of Velcro 9 is connected to the inner side of the sealing sleeve 3, and a first loop surface of Velcro 8 is connected to the uppermost outer side of the movable bag body 2. The sealing treatment above the turnover bag can be quickly completed through the adhesion of the first loop surface of Velcro 8 and the first hook surface of Velcro 9.

[0032] Optionally, reference can be made to Figure 4 , when further improving the sealing performance inside the turnover bag, a sealing patch 10 can be adhered. The connection of the sealing patch 10 is mainly achieved by adhering the second hook surface of Velcro 11 on the surface to a plurality of second loop surfaces of Velcro 12 on the inner side of the movable bag body 2. The second loop surfaces of Velcro 12 are all distributed at both ends of the first threaded ring 5, mainly to block the first threaded ring 5 and effectively improve the sealing performance of the turnover bag.

[0033] Working principle: When using the present utility model, the turnover bag can adjust the internal storage space of the turnover bag by longitudinally adjusting the position of the movable bag body 2 in the main bag body 1. After the first thread ring 5 on the surface of the movable bag body 2 is aligned with the jack 6 on the surface of the main bag body 1, insert the first bolt 7 to fix the position of the movable bag body 2. It can be flexibly adjusted according to the actual volume of the item. At the same time, when the movable bag body 2 moves longitudinally, the movable bag body 2 can pull the movable belts 13 fixed at both ends to move. The movable belts 13 are inserted into the inner grooves of the elastic belts 4 and then move in the inner grooves. After the position of the movable bag body 2 is fixed, then connect the second bolt 15 to the corresponding second thread ring 14 to complete the fixation of the movable belts 13.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
