Description

Technical Field

[0001] The utility model relates to a box body connection structure, in particular to a box body elastic sheet type connection structure. Background Art

[0002] At present, the Chinese patent with the publication number CN220587679U discloses a zipper installation structure for a seamless travel suitcase, which includes an upper suitcase shell, a lower suitcase shell and a zipper installation component. The zipper installation component includes a frame profile and a zipper component. The frame profile is provided with a box body installation slot. Protrusions are provided on both the upper suitcase shell and the lower suitcase shell. A recess is provided in the installation slot. The frame profile and the suitcase shell are connected through the cooperation of the recess and the protrusion.

[0003] The above patent still has deficiencies. The above-mentioned profile frame and the suitcase shell need to be pressed together during the assembly process. During the assembly process, the protrusion will expand the installation slot. After continuing to press the profile frame, the protrusion enters the recess. At this time, the installation slot will return to its original size, so that the protrusion and the recess will not be easily separated. The structural size of the protrusion and the recess is related to the elastic limit of the profile frame. Therefore, when the protrusion is designed to be larger, the higher the elastic limit requirement for the profile frame, and at the same time, it will increase the difficulty of installing the profile frame. When the protrusion is designed to be smaller, the connection strength between the profile frame and the suitcase shell is lower. When more clothes are placed in the suitcase, a certain pulling force will be generated between the profile frame and the suitcase shell. The suitcase is also prone to bumps during use. Therefore, wear is likely to occur between the protrusion and the recess, resulting in the profile frame being easily separated from the suitcase shell. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a box body elastic sheet type connection structure, which has the advantages of small installation difficulty and high connection strength.

[0005] To solve the above technical problems, the technical solution of the utility model is: a box body elastic sheet type connection structure, which includes a suitcase shell and a connection frame, and further includes a clamping barb. The clamping barb is inclined on the suitcase shell. A clamping groove is provided on the connection frame. An abutting groove is provided in the clamping groove. During the process of the end of the suitcase shell being inserted into the clamping groove, the connection frame abuts against the clamping barb and causes it to elastically deform. When the end of the suitcase shell completely enters the clamping groove, the clamping barb abuts against the abutting groove.

[0006] Through the above-mentioned technical means, by setting the snap-fitting barb and the abutment groove, when the end of the luggage case shell is snapped into the connecting frame, the snap-fitting barb abuts the abutment groove, thereby achieving the purpose of fixing the luggage case shell and the connecting frame, and by increasing the material strength of the snap-fitting barb, the connection strength of the luggage case shell and the connecting frame can be increased. By the connecting frame abutting the snap-fitting barb, the snap-fitting barb is elastically deformed toward the direction of the luggage case shell, thereby reducing its installation difficulty.

[0012] Through the above technical means, by providing a folded edge, the snap-fitting hook is directly inserted into the installation groove and fixed, and at the same time, the elastic snap-fitting part is more likely to be elastically deformed.

[0013] Preferably, the mounting portion further comprises a second folded edge, and the second folded edge is arranged on a side of the first folded edge away from the elastic clamping portion and abuts against the luggage case shell.

[0014] Through the above technical means, by setting the second folded edge, the snap-on hook is not easy to fall off when installed in the installation groove, and plays a role in limiting the position of the elastic snap-on part when the end of the luggage case shell is snapped into the snap-on groove.

[0015] Preferably, the mounting portion further comprises a folded edge three, wherein the folded edge three is arranged at one end of the folded edge two, the folded edge three abuts against the top surface of the luggage case shell, and an arc transition angle is formed between the folded edge two and the folded edge three.

[0016] Through the above technical means, by forming an arc transition angle between the third fold edge and the second fold edge, a certain guiding effect is played when the end of the luggage case shell is inserted into the snap-in groove, and the elastic snap-in portion is further fixed.

[0017] Preferably, a plurality of mounting grooves are formed in the trunk shell, and a plurality of first flanges and second flanges are provided on the elastic clamping portion, and the first flanges and the second flanges pass through the corresponding mounting grooves.

[0018] By the above technical means, by providing a plurality of mounting grooves and providing a plurality of first flanges and second flanges that cooperate with the elastic clamping portion, the connection strength between the elastic clamping portion and the trunk shell is increased, and a certain elastic deformation is ensured between the elastic clamping portion and the first flange.

Detailed implementation manners

[0031] The following further details the specific implementation manners of the present utility model in conjunction with the accompanying drawings, so that the technical solutions of the present utility model are easier to understand and master. Embodiment

[0032] A box body elastic sheet type connection structure, as Figure 1 , Figure 2 shown, includes a trunk housing 1 and a connecting frame 2. The trunk housing 1 includes an upper trunk housing 3 and a lower trunk housing 4. The connecting frame 2 includes an upper frame 5 and a lower frame 6. The upper frame 5 and the lower frame 6 are both provided with clamping grooves 7. The upper frame 5 and the lower frame 6 are respectively provided with a mutually cooperating clamping block 8 and a clamping slot 9, which play a guiding role when the trunks are combined and are applicable to snap-type trunks. It also includes a clamping barb 10. The clamping barb 10 is inclined and is detachably arranged on the trunk housing 1. An abutting groove 11 is arranged in the clamping groove 7. During the process of the end of the trunk housing 1 being inserted into the clamping groove 7, the connecting frame 2 abuts against the clamping barb 10 and causes it to elastically deform. When the end of the trunk housing 1 completely enters the clamping groove 7, the clamping barb 10 abuts against the abutting groove 11.

[0033] By increasing the material strength of the clamping barb 10 to prevent its deformation, the connection strength between the trunk housing 1 and the connecting frame 2 can be increased. At the same time, by the connecting frame 2 abutting against the clamping barb 10, a certain elastic deformation occurs at the bottom of the clamping barb 10, so that the clamping barb 10 can abut against the abutting groove 11, reducing its installation difficulty. At the same time, when the clamping barb 10 is deformed or damaged, only the clamping barb 10 needs to be replaced, thereby reducing the maintenance cost.

[0034] As Figure 2 , Figure 4As shown in the figure, an installation groove 12 is formed on the trunk shell 1. The snap hook 10 includes an elastic snap portion 13 and an installation portion 14. The installation portion 14 is connected to the installation groove 12. The installation portion 14 includes a first flange 15, a second flange 16, and a third flange 17. The elastic snap portion 13, the first flange 15, the second flange 16, and the third flange 17 are integrally bent. The first flange 15, the second flange 16, and the third flange 17 form a clamping groove 18, which clamps the trunk shell 1 through the clamping groove 18, thereby ensuring the installation stability of the snap hook 10. The elastic snap portion 13 is arranged at the side end of the first flange 15. The elastic snap portion 13 is inclined and abuts against the abutting groove 11 at the inner end face of the trunk shell 1. When the end of the trunk shell 1 is inserted into the snap groove 7, a certain elastic deformation occurs between the elastic snap portion 13 and the first flange 15.

[0035] The first flange 15 is arranged in the installation groove 12. The second flange 16 is arranged on the side of the first flange 15 away from the elastic snap portion 13. The second flange 16 abuts against the outer end face of the trunk shell 1. The third flange 17 is arranged at one end of the second flange 16. The third flange 17 abuts against the top surface of the trunk shell 1. An arc transition angle 19 is formed between the second flange 16 and the third flange 17. By arranging the second flange 16 and the third flange 17, the snap hook 10 is not easily detached when installed in the installation groove 12, and plays a role in restricting the position of the elastic snap portion 13 when the end of the trunk shell 1 is inserted into the snap groove 7. By forming an arc transition angle 19 between the third flange 17 and the second flange 16, it plays a certain guiding role when the end of the trunk shell 1 is inserted into the snap groove 7. The width of the snap groove 7 is sufficient for the first flange 15, the second flange 16, and the third flange 17 to pass through. By the third flange abutting against the top surface of the trunk shell 1, it prevents the snap hook 10 from moving when the end of the trunk shell 1 is inserted into the snap groove 7.

[0036] As Figure 3 、 Figure 4 shown in the figure, a plurality of installation grooves 12 are formed on the trunk shell 1. The elastic snap portion 13 is an integral long plate. The elastic snap portion 13 is provided with a plurality of first flanges 15, second flanges 16, and third flanges 17. The first flanges 15, the second flanges 16, and the third flanges 17 pass through the corresponding installation grooves 12, reducing the connection area between the first flange 15 and the elastic snap portion 13 to a certain extent, thereby reducing the force of elastic deformation between the elastic snap portion 13 and the first flange 15 and lowering the installation difficulty.

[0037] The clamping groove 7 is also provided with a convex block 20. An avoidance groove 21 is formed between the convex block 20 and the clamping groove 7. When the end of the luggage case body 1 completely enters the clamping groove 7, the convex block 20 abuts against the outer end face of the luggage case body 1. When the end of the luggage case body 1 enters the clamping groove 7 through the convex block 20 and the avoidance groove 21, the connecting frame 2 can swing by a certain amplitude, thereby preventing hard connection between the connecting frame 2 and the luggage case body 1, and avoiding easy damage to the luggage when it is impacted. Embodiment

[0038] The difference between the second embodiment and the first embodiment is that, as Figure 5 、 Figure 6 shown, the connecting frame 2 is replaced by a pair of rigid mounting strips 22. A zipper 30 mounting strip one 23 is provided on the rigid mounting strip 22. The rigid mounting strip 22 is formed by extrusion of aluminum alloy. The rigid mounting strip 22 is also provided with a clamping groove 7. An abutting groove 11 is provided in the clamping groove 7. A connecting groove one 24 is also provided on the mounting strip. Limit posts one 25 are provided at both ends of the side wall of the connecting groove one 24. The two limit posts one 25 and the connecting groove one 24 form an inner groove one 26. The inner groove one 26 is square. A clamping groove 9 one is formed between the two limit posts one 25. The clamping groove 9 one and the inner groove one 26 form a T-shaped groove.

[0039] The zipper 30 mounting strip one 23 includes a zipper 30 sewing part one 28 and a clamping part one 29. The clamping part one 29 and the zipper 30 sewing part one 28 form a T-shaped block. Through the cooperation of the T-shaped block and the T-shaped groove, the zipper 30 sewing part one 28 is detachably arranged on the rigid mounting strip 22. The right chain teeth and the left chain teeth of the zipper 30 are respectively sewn on the two zipper 30 sewing parts one 28. The above-mentioned rigid mounting strip is applicable to a zipper-type luggage.

[0040] Of course, the above are only typical examples of the present invention. In addition, the present invention 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 the present invention.
