Description
Technical Field
[0001] This utility model relates to the field of bags, and more specifically, to a bag with a hidden clasp. Background Technology
[0002] Handbags are a common household item, used to carry small items. Depending on the occasion and the contents, people choose different types of bags, such as shoulder bags with long straps or handbags. While some handbags on the market can switch between shoulder bags and handbags, the process is cumbersome and inconvenient, and the clasps on the sides can detract from the bag's overall aesthetic appeal. Utility Model Content
[0003] This utility model provides a bag with a hidden clasp, which aims to improve the existing handbags that, although they can switch between a shoulder bag with a long strap and a handbag, are cumbersome to operate and inconvenient to use, and the clasps on both sides of the handbag affect the overall aesthetics of the bag.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a concealed clasp bag, comprising a bag body and a bag chain. The bag body includes two symmetrical first shells and second shells, which are hinged together on one side edge. The first shell and the second shell have handle holes. A rotatable first connecting part is installed on the inner side wall of the first shell near the handle hole, and a rotatable second connecting part is installed on the inner side of the second shell near the handle hole. The first connecting part and the second connecting part are offset. One end of the bag chain is detachably connected to the first connecting part, and the other end is detachably connected to the second connecting part. Magnets are provided on one side of the first shell and the second shell around the handle hole.
[0005] Furthermore, a hemispherical fixing block is installed on the first housing at the position of the handle hole, the fixing block extends toward one side of the second housing, a positioning groove is opened at the bottom of the fixing block, and a spherical protrusion is installed on the second housing at the position of the handle hole.
[0006] Furthermore, the first connecting part includes a first base plate and a first connecting ring. The first base plate is locked to the inner side wall of the first housing by screws, and the first connecting ring is hinged to the first base plate by a thin sheet.
[0007] Furthermore, the second connecting part includes a second base plate and a second connecting ring. The second base plate is locked to the inner side wall of the second housing by screws, and the second connecting ring is hinged to the second base plate by a thin sheet.
[0008] Furthermore, connecting fabric is provided on the inner sides of both ends of the first housing and the second housing.
[0009] Furthermore, strips of fabric are installed at the hinge connection points of the first housing and the second housing.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model relates to a bag with an adjustable shoulder strap, comprising a bag body and a chain. The bag body includes two symmetrical first and second shells, hinged together at one edge. Both shells have handle holes. A rotatable first connecting part is installed on the inner sidewall of the first shell near the handle hole, and a rotatable second connecting part is installed on the inner side of the second shell near the handle hole. The first and second connecting parts are staggered. One end of the chain is detachably connected to the first connecting part, and the other end is detachably connected to the second connecting part. Magnets are disposed around one side of the first and second shells near the handle holes. When the first and second shells are closed, they form a handbag. The first and second connecting parts are placed inside the first and second shells, with the handle hole serving as the handle. When switching to a shoulder bag with a long strap, the first and second connecting parts are rotated out of the bag, and connected by the chain to form the shoulder bag. The structure is simple, and switching between the two different types of bags is easy, practical, and convenient. The hidden chain enhances the aesthetics. Attached Figure Description

[0025] Example
[0026] like Figure 1-3 As shown, this utility model provides a concealed clasp bag, including a bag body and a clasp. The bag body includes two symmetrical first shells 10 and second shells 20, which are hinged together on one side edge. Each shell has a handle hole 30. When the first shells 10 and 20 are closed, they form a handbag, with the handle hole 30 serving as the handle. In this embodiment, strips of fabric are installed on the first shells 10 and 20 at the hinge connection point, covering the hinge for both aesthetic purposes and to prevent the hinge from being exposed and causing injury. Magnets 40 are arranged around one side of the handle hole 30 on the first shells 10 and 20. When closed, the magnets 40 attract each other, effectively closing the opening.
[0027] like Figure 1-3 As shown, a hemispherical fixing block 101 is installed at the handle hole 30 of the first housing 10. The fixing block 101 extends towards the second housing 20, and a positioning groove 1011 is formed at the bottom of the fixing block 101. A spherical protrusion 201 is installed at the handle hole 30 of the second housing 20. Specifically, when the first housing 10 and the second housing 20 are closed, the spherical protrusion 201 of the second housing 20 is engaged with the positioning groove 1011 at the bottom of the fixing block, which locks the first housing 10 and the second housing 20. When it is necessary to open, the handle hole 30 of the second housing 20 is pressed, causing the spherical protrusion 201 to disengage from the positioning groove 1011, thereby opening the first housing 10 and the second housing 20, and further closing the opening of the handbag.
[0028] like Figure 1-3As shown, a rotatable first connecting part is installed on the inner wall of the first housing 10 near the handle hole 30, and a rotatable second connecting part is installed on the inner wall of the second housing 20 near the handle hole 30. The first and second connecting parts are staggered. One end of the chain is detachably connected to the first connecting part, and the other end is detachably connected to the second connecting part. Specifically, the first connecting part includes a first base plate 103 and a first connecting ring 102. The first base plate 103 is locked to the inner wall of the first housing 10 by screws. The first connecting ring 102 is hinged to the first base plate 103 by a thin sheet. The first connecting ring 102 is rotatably connected to the first base plate 103 by the thin sheet. The first connecting ring 102 rotates around the hinge point to switch between two states: the first connecting ring 102 is inside or outside the first housing 10. The second connecting part includes a second base plate 203 and a second connecting ring 202. The connecting ring 202 and the second base plate 203 are locked to the inner wall of the second housing 20 by screws. The second connecting ring 202 is hinged to the second base plate 203 by a thin sheet. The second connecting ring 202 is rotatably connected to the second base plate 203 by the thin sheet. The second connecting ring 202 rotates around the hinge point, realizing the switching between two states: the second connecting ring 202 is placed inside or outside the second housing 20. When used as a handbag, the first connecting ring 102 and the second connecting ring 202 are rotated into the bag. When switching to the long bag strap, the first connecting ring 102 and the second connecting ring 202 are rotated out of the bag. The two ends of the chain are connected to the first connecting ring 102 and the second connecting ring 202, thus forming a shoulder strap that can be carried on the back or across the body. The switching between the two states is simple and convenient.
[0029] In addition, connecting fabric 50 is provided on the inner sides of both ends of the first housing 10 and the second housing 20. The connecting fabric 50 facilitates the formation of a space for holding items with the first housing 10 and the second housing 20, and also serves as a limit to prevent damage caused by large-angle rotation of the first housing 10 and the second housing 20 around the hinge point.
[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
