[0001] The utility model relates to the technical field of suitcase accessories, in particular to a folding connection structure for a box body. Background Art

[0002] With the development of road traffic, people's travel has become more convenient and frequent. To meet the travel needs, suitcases have gradually become an essential travel item. Among them, zipper suitcases are usually made of lightweight materials, with a light weight and convenient to carry, becoming the choice of most consumers.

[0003] The utility model with the publication number CN215225283U discloses a suitcase buckle, a suitcase zipper combination mechanism and a suitcase. The suitcase buckle includes a first buckle component and a second buckle component that cooperates with the first buckle component. The first buckle component has a first side portion and a second side portion opposite to the first side portion. The first buckle component is provided with a first accommodation groove corresponding to the first side portion and a first card slot corresponding to the second side portion. The positions of the first accommodation groove and the first card slot are offset from each other. The second buckle component has a third side portion and a fourth side portion opposite to the third side portion. The third side portion is close to the second side portion. The second buckle component is provided with a second accommodation groove corresponding to the fourth side portion and a second card slot corresponding to the third side portion. The positions of the second accommodation groove and the second card slot are offset from each other.

[0004] In the above technical solution, the installation of the buckle is completed through the insertion and cooperation between the card slot and the box body. However, it only inserts the buckle onto the shell and does not have any limiting structure. During subsequent use, the box body being hit or the zipper being pulled forcefully is likely to cause the buckle to fall off the shell, resulting in poor durability of the suitcase. Summary of the Utility Model

[0005] In order to improve the durability of the suitcase, the present application provides a folding connection structure for a box body.

[0006] The folding connection structure for a box body provided by the present application adopts the following technical solution:

[0007] A folding connection structure for a box body includes a box body, a connecting piece and a zipper tape. The zipper tape is arranged on the connecting piece. An installation part is provided on the box body. An installation groove that can be inserted and cooperated with the installation part is opened on the connecting piece. A limiting part is rotatably connected to the connecting piece along the length direction of the connecting piece. A "C"-shaped deformation part is provided on the connecting piece. Two ends of the "C"-shaped deformation part are respectively fixedly connected to the connecting piece and the limiting part. When the connecting piece is installed on the box body, the installation groove is inserted and cooperated with the installation part, the "C"-shaped deformation part is deformed until its two ends are in abutment, the limiting part and the installation groove jointly surround the installation part and the limiting part abuts against the installation part.

[0008] By adopting the above technical solution, the installation of the connecting piece on the box body is completed by plugging and fitting the installation groove with the installation portion, and the deformation of the "C"-shaped deformation portion causes the abutment portion to abut against the installation portion, so that the installation groove and the abutment portion together cover the installation portion, and the position of the installation portion in the installation groove is limited, thereby reducing the possibility of the installation portion detaching from the installation groove, thereby improving the durability of the suitcase.

[0009] Preferably, an abutment portion is provided at one end of the limiting portion away from the “C”-shaped deformation portion, and when the connecting member is mounted on the mounting portion, the abutment portion abuts against the box body.

[0010] By adopting the above technical solution, when the connecting piece is installed, the abutting portion abuts against the box body, and the friction between the box body and the abutting portion reduces the possibility of the mounting portion detaching from the mounting groove, thereby improving the durability of the suitcase.

[0011] Preferably, the contact area between the abutting portion and the box body is much larger than the contact area between the limiting portion and the mounting portion.

[0012] By adopting the above technical solution, when installing the connecting piece, the abutting part can be bent to cause the "C"-shaped deformation part to deform, so as to facilitate the installation of the connecting piece on the box body; and through the friction between the box body and the abutting part, the possibility of the installation part being separated from the installation groove is reduced, thereby improving the durability of the suitcase.

[0013] Preferably, a deformation groove is provided on the connecting member, and the deformation groove is located beside the connection between the “C”-shaped deformation portion and the connecting member.

[0014] By adopting the above technical solution, the stress concentration at the connection between the "C"-shaped deformation part and the connecting piece is reduced, thereby reducing the possibility of the "C"-shaped deformation part breaking, thereby improving the durability of the suitcase.

[0015] Preferably, the zipper tape is provided with a connecting strip, and the connecting piece is provided with a connecting groove which can cooperate with the connecting strip. When the zipper tape is installed on the connecting piece, the connecting strip cooperates with the connecting groove.

[0016] By adopting the above technical solution, the installation of the zipper tape is facilitated through the cooperation between the connecting strip and the connecting groove.

[0017] Preferably, first limiting protrusions are respectively provided on both side surfaces in the width direction of the connecting groove, and limiting grooves that can cooperate with the first limiting protrusions are respectively opened on both sides in the width direction of the connecting strip. When the zipper tape is installed on the connecting piece, the first limiting protrusion cooperates with the limiting groove.

[0018] By adopting the above technical solution, the position of the connecting strip in the connecting groove is limited through the cooperation between the first limiting convex part and the limiting groove, reducing the possibility of the connecting strip disengaging from the connecting groove, thereby reducing the possibility of the zipper tape disengaging from the connecting piece, so as to improve the durability of the luggage.

[0019] Preferably, a second limiting convex part is provided on one side of the notch of the connecting groove. When the zipper tape is installed on the connecting piece, the second limiting convex part abuts against the side surface of the connecting strip away from the bottom wall of the connecting groove.

[0020] By adopting the above technical solution, by making the second limiting convex part abut against the connecting strip, the position of the connecting strip in the connecting groove is further limited, further reducing the possibility of the connecting strip disengaging from the connecting groove, and further reducing the possibility of the zipper tape disengaging from the connecting piece, so as to improve the durability of the luggage.

[0021] The technical effects of the present utility model are mainly reflected in the following aspects:

[0022] 1. By providing a "C"-shaped deformation part and a limiting part, the present utility model completes the installation of the connecting piece on the box body through the insertion and cooperation of the installation groove and the installation part, and makes the abutting part abut against the installation part through the deformation of the "C"-shaped deformation part, so as to wrap the installation part with the installation groove and the abutting part together, limit the position of the installation part in the installation groove, reduce the possibility of the installation part disengaging from the installation groove, and thus improve the durability of the luggage;

[0023] 2. By providing an abutting part, after the connecting piece is installed, the abutting part abuts against the box body, and through the frictional force between the box body and the abutting part, the possibility of the installation part disengaging from the installation groove is reduced, thereby improving the durability of the luggage;

[0024] 3. By providing a deformation groove, the stress concentration at the connection between the "C"-shaped deformation part and the connecting piece is reduced, thereby reducing the possibility of the "C"-shaped deformation part breaking, so as to improve the durability of the luggage.

Detailed implementation manners

[0030] The following is further described in detail with reference to the attached Figures 1-4 drawings to make the technical solutions of the present application easier to understand and master.

[0031] An embodiment of the present application discloses a folding connection structure for a box body.

[0032] Referring to Figures 1-4 , a folding connection structure for a box body in this embodiment includes a box body 2, a connecting piece 1 and a zipper tape 3. The zipper tape 3 is installed on the connecting piece 1. An installation part 21 is fixedly connected to the edge part of the box body 2. An installation groove 11 that can be inserted and matched with the installation part 21 is provided on the connecting piece 1. A limiting part 13 is rotatably connected to the connecting piece 1 along the length direction of the connecting piece 1. A "C"-shaped deformation part 12 is fixedly connected to the connecting piece 1. Two ends of the "C"-shaped deformation part 12 are respectively fixedly connected to the connecting piece 1 and the limiting part 13. An abutting part 14 is fixedly connected to the end of the limiting part 13 away from the "C"-shaped deformation part 12. The connecting piece 1, the "C"-shaped deformation part 12, the limiting part 13 and the abutting part 14 are integrally formed. When the connecting piece 1 is installed on the box body 2, the installation groove 11 is inserted and matched with the installation part 21. The "C"-shaped deformation part 12 is deformed until its two ends abut against each other. The limiting part 13 is parallel to the bottom surface of the installation groove 11. The limiting part 13 abuts against the end of the installation part 21 away from the bottom of the installation groove 11, so that the limiting part 13 and the installation groove 11 jointly surround the installation part 21, and the abutting part 14 abuts against the box body 2.

[0033] Referring to Figures 1-4 , through the insertion and matching of the installation groove 11 and the installation part 21, and by deforming the "C"-shaped deformation part 12 to make the abutting part 14 abut against the installation part 21, the installation of the connecting piece 1 on the box body 2 is completed, so that the installation groove 11 and the abutting part 14 jointly enclose the installation part 21, limit the position of the installation part 21 in the installation groove 11, and reduce the possibility of the installation part 21 disengaging from the installation groove 11, thereby improving the durability of the luggage. After the connecting piece 1 is installed, the abutting part 14 abuts against the box body 2. Through the frictional force between the box body 2 and the abutting part 14, the possibility of the installation part 21 disengaging from the installation groove 11 is reduced, thereby improving the durability of the luggage.

[0034] Referring to Figures 1-4The contact area between the abutment portion 14 and the box body 2 is much larger than the contact area between the limiting portion 13 and the mounting portion 21. When installing the connector 1, the abutment portion 14 can be bent to deform the "C"-shaped deformation portion 12, which is convenient for installing the connector 1 on the box body 2; and the friction between the box body 2 and the abutment portion 14 reduces the possibility of the mounting portion 21 being separated from the mounting groove 11, thereby improving the durability of the suitcase.

[0035] Reference Figures 1-4 A deformation groove 15 is provided on the connecting member 1, and the deformation groove 15 is located beside the connection between the "C"-shaped deformation portion 12 and the connecting member 1. The stress concentration at the connection between the "C"-shaped deformation portion 12 and the connecting member 1 is reduced, thereby reducing the possibility of the "C"-shaped deformation portion 12 breaking, thereby improving the durability of the suitcase.

[0036] Reference Figure 4 The two side shells of the suitcase are respectively fixedly connected with mounting parts 21, and are respectively connected to the connecting parts 1 with zipper strips installed. The zipper strips on the two connecting parts 1 can merge the two side shells of the suitcase.

[0037] Reference Figures 2-4 The zipper tape 3 is fixedly connected with a connecting strip 31, and the connecting member 1 is provided with a connecting groove 16 that can match with the connecting strip 31. When the zipper tape 3 is installed on the connecting member 1, the connecting strip 31 matches with the connecting groove 16. The matching between the connecting strip 31 and the connecting groove 16 facilitates the installation of the zipper tape 3. The two side surfaces in the width direction of the connecting groove 16 are respectively fixedly connected with a first limiting protrusion 161, and the two sides in the width direction of the connecting strip 31 are respectively provided with a limiting groove 311 that can match with the first limiting protrusion 161. When the zipper tape 3 is installed on the connecting member 1, the first limiting protrusion 161 matches with the limiting groove 311. A second limiting protrusion 162 is fixedly connected to one side of the notch of the connecting groove 16. When the zipper tape 3 is installed on the connecting member 1, the second limiting protrusion 162 abuts against the side surface of the connecting strip 31 away from the bottom wall of the connecting groove 16.

[0038] Reference Figures 2-4 The first limiting protrusion 161 cooperates with the limiting groove 311 to limit the position of the connecting strip 31 in the connecting groove 16, thereby reducing the possibility of the connecting strip 31 being separated from the connecting groove 16, thereby reducing the possibility of the zipper tape 3 being separated from the connecting member 1, thereby improving the durability of the suitcase. The second limiting protrusion 162 abuts against the connecting strip 31, thereby further limiting the position of the connecting strip 31 in the connecting groove 16, thereby further reducing the possibility of the connecting strip 31 being separated from the connecting groove 16, thereby further reducing the possibility of the zipper tape 3 being separated from the connecting member 1, thereby improving the durability of the suitcase.

[0039] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
