Description

Technical Field

[0001] This utility model relates to the field of hard or semi-hard luggage technology, and in particular to a luggage elastic connection structure and its application. Background Technology

[0002] Existing suitcases consist of an upper shell, a lower shell, and a connecting hinge between the upper and lower shells. The length of the existing connecting hinge is fixed and it is relatively rigid. It is generally required to be sewn between the upper and lower shells. On the one hand, it is inconvenient to install and reduces processing efficiency to some extent. On the other hand, the distance between the upper and lower shells remains unchanged during the packing process (because the connecting hinge cannot be retracted), which takes up a lot of space. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a flexible connection structure for luggage and its application in luggage.

[0004] This utility model proposes an elastic connection structure for bags and luggage, including an elastic deformation part, a first snap-fit ​​part installed on a first side of the elastic deformation part, and the hardness of the first snap-fit ​​part being greater than the hardness of the elastic deformation part; and / or:

[0005] A second snap-fit ​​portion is installed on the second side of the elastic deformation portion, and the hardness of the second snap-fit ​​portion is greater than the hardness of the elastic deformation portion.

[0006] In actual use, the first locking part is locked to the upper shell of the suitcase, and / or the second locking part is locked to the lower shell of the suitcase, which facilitates the installation of the connecting mechanism. Since the elastic deformation part can deform, the sides of the upper and lower shells can come into contact during the user's packing process, thereby reducing the footprint to a certain extent. The suitcase can still be laid flat and used in a small space.

[0007] As a further optimization of this utility model, the first snap-fit ​​portion and / or the second snap-fit ​​portion includes a snap-fit ​​plate.

[0008] As a further optimization of this utility model, the elastically deformable part is provided with a first through-hole limiting member, the first through-hole limiting member contacts the first snap-fit ​​part so that the first snap-fit ​​part is perpendicular to the elastically deformable part, and the end of the first through-hole limiting member away from the first snap-fit ​​part has a first extended limiting part; and / or:

[0009] The elastic deformation part is covered with a second through-limiting member. The second through-limiting member contacts the second snap-fit ​​part so that the second snap-fit ​​part is perpendicular to the elastic deformation part. The end of the second through-limiting member away from the second snap-fit ​​part has a second extended limiting part.

[0010] As a further optimization of this utility model, a first limiting ring is provided on the end of the first through-hole limiting member away from the first extended limiting portion, and the first limiting ring contacts the first snap-fit ​​portion; and / or:

[0011] The second through-type limiting member has a second limiting ring on one end away from the second extended limiting portion, and the second limiting ring contacts the second snap-fit ​​portion.

[0014] As a further optimization of this utility model, the first limiting ring is engaged with the first through-hole limiting member; and / or:

[0015] The second limiting ring is engaged with the second through-limiting component.

[0016] As a further optimization of this utility model, the elastic deformation part is an elastic band.

[0017] As a further optimization of this utility model, the elastic band is connected to the first snap-fit ​​part and / or the second snap-fit ​​part by sewing.

[0018] A suitcase includes an upper shell and a lower shell, wherein the upper shell and the lower shell are further provided with the aforementioned elastic connection structure for luggage, the upper shell has a first mounting through hole, a first snap-fit ​​portion passes through the first mounting through hole and has a portion that abuts against the inner wall of the upper shell, and / or:

[0019] The lower housing has a second mounting through hole, and the second snap-fit ​​part passes through the second mounting through hole and has a portion that abuts against the inner wall of the upper housing.

[0020] As a further optimization of this utility model, a zipper is provided between the upper shell and the lower shell, the elastic deformation part is located on the outside of the zipper, and when the zipper is in the pulled state, the elastic deformation part is in the original length state.

[0021] The proposed elastic connection structure for luggage and its application in luggage facilitates the assembly of luggage and increases assembly efficiency. Furthermore, the elastic deformation part can change the distance between the upper and lower shells when the luggage is in the open state. Moreover, if either the upper or lower shell of the luggage is damaged, it is easy to replace the damaged upper or lower shell.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-5 The elastic connection structure of the bag shown includes an elastic deformation part 1. In this embodiment, the elastic deformation part 1 is an elastic band with a width of 5cm-20cm. A first snap-fit ​​part 2 is installed on the first side of the elastic deformation part 1. The first snap-fit ​​part 2 is made of plastic material and the hardness of the first snap-fit ​​part 2 is greater than that of the elastic deformation part 1.

[0033] A second snap-fit ​​part 3 is installed on the second side of the elastic deformation part 1. The second side is opposite to the first side. The second snap-fit ​​part 3 is made of plastic material. The hardness of the second snap-fit ​​part 3 is greater than that of the elastic deformation part 1. The elastic deformation part 1 is connected to the first snap-fit ​​part 2 and the second snap-fit ​​part 3 by sewing.

[0034] In actual use, the first snap-fit ​​part 2 snaps into the upper shell 9 of the suitcase, and the second snap-fit ​​part snaps into the lower shell 10 of the suitcase, which facilitates the installation of the connecting mechanism. Since the elastic deformation part 1 can deform, the sides of the upper shell 9 and the lower shell 10 can come into contact during the user's packing process, thereby reducing the footprint to a certain extent. The suitcase can still be used in a small space. Moreover, if the upper shell 9 or the lower shell 10 of the suitcase is damaged, it is easy to replace the damaged upper shell 9 or the lower shell 10.

[0035] Preferably, both the first snap-fit ​​part 2 and the second snap-fit ​​part 3 include snap-fit ​​plates. The middle part of the snap-fit ​​plate is connected to the elastic deformation part 1 by sewing. When passing through the through hole on the luggage box, the snap-fit ​​plate is parallel to the elastic deformation part 1. Then, the snap-fit ​​plate is adjusted so that the snap-fit ​​plate is perpendicular to the elastic rod deformation part, thereby completing the connection between the snap-fit ​​plate and the luggage box.

[0036] To facilitate the installation of the connection structure, preferably, the elastic deformation part 1 is fitted with a first through-hole limiting member 4. The first through-hole limiting member 4 contacts the first snap-fit ​​part 2 so that the first snap-fit ​​part 2 is perpendicular to the elastic deformation part 1. The end of the first through-hole limiting member 4 away from the first snap-fit ​​part 2 has a first extended limiting part 40. It should be noted that the thickness of the through hole of the first through-hole limiting member 4 is greater than the thickness of the elastic deformation part 1 and less than the sum of the thicknesses of the elastic rod deformation part and the first snap-fit ​​part 2. Thus, after the first snap-fit ​​part 2 is sewn on, the first through-hole limiting member 4 can be positioned.

[0037] The elastic deformation part 1 is covered with a second through-hole limiting member 5. The second through-hole limiting member 5 contacts the second snap-fit ​​part 3 so that the second snap-fit ​​part 3 is perpendicular to the elastic deformation part 1. The end of the second through-hole limiting member 5 away from the second snap-fit ​​part 3 has a second extended limiting part 50. It should be noted that the thickness of the through hole of the second through-hole limiting member 5 is greater than the thickness of the elastic deformation part 1 and less than the sum of the thicknesses of the elastic rod deformation part and the second snap-fit ​​part 3. Thus, after the second snap-fit ​​part 3 is sewn on, the second through-hole limiting member 5 can be positioned.

[0038] In order to further ensure the stability of the connection between the first through-limiting member 4 and the second through-limiting member 5, preferably, the first through-limiting member 4 is provided with a first limiting ring 6 at the end away from the first extended limiting part 40, and the first limiting ring 6 contacts the first snap-fit ​​part 2.

[0039] A second limiting ring 7 is provided on the end of the second through-type limiting member 5 away from the end of the second extended limiting portion 50, and the second limiting ring 7 contacts the second engaging portion 3. Preferably, the first limiting ring 6 engages with the first through-type limiting member 4, and the second limiting ring 7 engages with the second through-type limiting member 5;

[0040] To further ensure the stability of the connection between the first through-hole limiting member 4 and the second through-hole limiting member 5, preferably, the hardness of the first limiting ring 6 is greater than the hardness of the first through-hole limiting member 4; and the hardness of the second limiting ring 7 is greater than the hardness of the second through-hole limiting member 5.

[0041] Specifically, the first limiting ring 6 engages with the first through-hole limiting member 4, and the second limiting ring 7 engages with the second through-hole limiting member 5. Multiple sets of engaging holes 8 are provided on both the first through-hole limiting member 4 and the second through-hole limiting member 5. Each engaging hole 8 has through holes and blind holes, and the multiple sets of engaging holes 8 are circumferentially distributed on the first through-hole limiting member 4 and the second through-hole limiting member 5. Engaging members are located within the first limiting ring 6 and the second limiting ring 7, and these engaging members match the engaging holes 8. When passing through a through-hole engaging hole 8, the engaging member contacts the elastically deformable part 1. This facilitates the disassembly and installation of the first limiting ring 6 and the second limiting ring 7. It should be noted that the first limiting ring 6 has the function of limiting the first through-limiting member 4 and clamping the elastic deformation part 1 inside the first through-limiting member 4, thereby preventing the elastic deformation part 1 from sliding relative to the first through-limiting member 4 under a small external force. Similarly, the second limiting ring 7 has the function of limiting the second through-limiting member 5 and clamping the elastic deformation part 1 inside the second through-limiting member 5.

[0042] like Figures 6-7 The suitcase shown includes an upper shell 9 and a lower shell 10. Similar to existing technologies, a zipper (not shown) connects the upper shell 9 and the lower shell 10. However, unlike existing technologies, the upper shell 9 and the lower shell 10 also feature the aforementioned elastic connection structure. The upper shell 9 has a first mounting hole 90, and a first latching part 2 passes through the first mounting hole 90, with the first latching part 2 having a portion that abuts against the inner wall of the upper shell 9. The lower shell 10 has a second mounting hole 100, and a second latching part 3 passes through the second mounting hole 100, with the second latching part 3 having a portion that abuts against the inner wall of the upper shell 9. The first mounting hole 90 and the second mounting hole 100 are located above or below the zipper.

[0043] Specifically, the first through-limiting member 4 and the second through-limiting member 5 are first sleeved on the outside of the elastic deformation part 1, and then the plastic and plate-shaped first snap-fit ​​part 2 and the second snap-fit ​​part 3 are installed by sewing.

[0044] Then, adjust the first snap-fit ​​part 2 to be parallel to the elastic deformation part 1 and insert it into the first mounting through hole 90. Then, the first limiting ring 6 passes through the first snap-fit ​​part 2 and adjust the first snap-fit ​​part 2 to be perpendicular to the elastic deformation part 1. Pull the elastic adjustment part to the outside of the upper housing 9 by external force so that the first limiting ring 6 abuts against the inner wall of the upper housing 9. Then, under the action of external force, the first through limiting member 4 is snapped into the first mounting through hole 90 and the first through limiting member 4 is snapped into the first limiting ring 6. At the same time, the first extension limiting part 40 abuts against the outside of the upper housing 9. The first limiting ring 6 has the function of limiting the first through limiting member 4 and clamping the elastic deformation part 1 inside the first through limiting member 4, thereby preventing the elastic deformation part 1 from sliding relative to the first through limiting member 4 under the action of a small external force. Through the above installation steps, the first through limiting member 4 and the upper housing 9 can be fixed at the same time, and the elastic limiting part 1 can be prevented from sliding relative to the upper housing 9 under the action of a small force.

[0045] Then, adjust the second snap-fit ​​part 3 to be parallel to the elastic deformation part 1 and insert it into the second mounting through hole 100. Then, the second limiting ring 7 passes through the second snap-fit ​​part 3 and adjust the second snap-fit ​​part 3 to be perpendicular to the elastic deformation part 1. Pull the elastic adjustment part to the outside of the lower housing 10 by external force so that the second limiting ring 7 abuts against the inner wall of the lower housing 10. Then, under the action of external force, the second through limiting member 5 is snapped into the second mounting through hole 100 and the second through limiting member 5 is snapped into the second limiting ring 7. At the same time, the second extension limiting part 50 abuts against the outside of the lower housing 10. The second limiting ring 7 has the function of limiting the second through limiting member 5 and clamping the elastic deformation part 1 inside the second through limiting member 5, thereby preventing the elastic deformation part 1 from sliding relative to the second through limiting member 5 under the action of a small external force. Through the above installation steps, the second through limiting member 5 and the upper housing 10 can be fixed at the same time, and the elastic limiting part 1 can be prevented from sliding relative to the upper housing 10 under the action of a small force.

[0046] Preferably, a zipper is provided between the upper housing 9 and the lower housing 10, the elastic deformation part is located on the outside of the zipper, and when the zipper is in the pulled state, the elastic deformation part is in the original length state.
