Description
Technical Field
[0001] The utility model relates to the technical field of bags, in particular to a messenger bag with expandable volume. Background Art
[0002] According to different occasions and uses, existing backpacks can be divided into different types such as backpacks, shoulder bags, and messenger bags. However, due to design limitations, the bag products currently available in the market can only fulfill one purpose, so they can only focus on one purpose and fail to meet the needs of users in different scenarios, which brings many inconveniences to use. For example, most existing messenger bags have limited capacity and cannot flexibly adapt to different load requirements. At the same time, when the bag is empty, the bag is too large and inconvenient to store or carry. Utility Model Content
[0003] In order to solve the above technical problems, the utility model designs a messenger bag with expandable volume.
[0004] The utility model adopts the following technical solutions:
[0005] A crossbody bag with expandable volume comprises a bag body, the bag body comprises an upper part, a bottom part, a side part, a front part and a rear part, an inner cavity is formed in the bag body, a bag opening is arranged on the upper part of the bag body, folds are arranged on the bottom part and the side part of the bag body respectively, a folding part that can be retracted and folded and expanded is formed between the front part and the rear part of the bag body through the folds, a side sliding male buckle and a side sliding female buckle are respectively installed on the front side and the rear side of the bottom of the bag body, and the side sliding male buckle and the side sliding female buckle are matched and buckled to be connected. After the bag body is folded and expanded in volume, the folded state is maintained by the buckling of the side sliding male buckle and the side sliding female buckle, and when it is necessary to unfold and expand the volume, it only needs to open the connection between the side sliding male buckle and the side sliding female buckle.
[0006] Preferably, a zipper is installed at the bag opening.
[0007] Preferably, the side of the package body is arranged in a triangular shape as a whole.
[0008] Preferably, the fold is formed by a seam mark on the package body.
[0009] Preferably, two pairs of side-sliding male buckles and side-sliding female buckles are installed on the front side and the rear side of the bottom, respectively.
[0010] The beneficial effects of the utility model are: (1) Additional storage: the messenger bag has built-in expansion, and the adjustable and retractable expansion function of the bottom and sides of the bag body provides additional internal storage space, which can be used to place more items; (2) Convenient expansion: the internal storage capacity can be expanded by simply opening the buckle at the bottom of the bag body.
