Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to an explosion-proof luggage frame structure. Background Technology

[0002] A suitcase, also known as a travel case or rolling suitcase, is a box carried when traveling to store belongings; it is a type of luggage. Suitcases are commonly used by travelers to transport items. Among various types of suitcases, hard-sided suitcases have become increasingly popular. Hard-sided suitcases typically consist of two opposing shells, a closure and / or locking mechanism attached to said shells, carrying handles, a telescopic handle, and wheels.

[0003] Suitcases typically have side frames. When in use, the two shells are closed, with their respective side frames fitting together. If the suitcase is overloaded, although the shells can be forced closed by pressing down, the items will subsequently expand to return to their original volume. This causes a significant outward force on both shells, preventing the side frames from maintaining their fit and leading to the suitcase bursting open. Furthermore, since suitcase handles are usually connected to one of the side frames, when a user grips the handle and lifts the suitcase upwards, the side frames bear a tremendous force, causing them to break apart and resulting in the suitcase bursting open. Therefore, it is necessary to improve the existing suitcase side frame structure. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an explosion-proof box frame structure, which can effectively solve the problem that the existing box frame structure cannot maintain a continuous fit when subjected to a large outward force, thus causing the box to burst open.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An explosion-proof box frame structure includes a first frame and a second frame that can be mated with each other; the first frame is annular and adapted to one of the boxes of a suitcase, the first frame having a first explosion-proof part and a second explosion-proof part, a first groove being formed between the first explosion-proof part and the second explosion-proof part; the second frame is annular and adapted to the other box of the suitcase, the second frame having a third explosion-proof part and a fourth explosion-proof part, the third explosion-proof part extending into the first groove, the third explosion-proof part being adapted to the first explosion-proof part, the fourth explosion-proof part being adapted to the second explosion-proof part, a second groove being formed between the third explosion-proof part and the fourth explosion-proof part, the aforementioned second explosion-proof part extending into the second groove.

[0006] As a preferred embodiment, the end of the first explosion-proof part has a first hook, and the end of the third explosion-proof part has a second hook, which is adapted to the first hook.

[0007] As a preferred embodiment, the end of the second explosion-proof part has a third hook, and the end of the fourth explosion-proof part has a fourth hook, the third hook and the fourth hook being adapted to each other.

[0008] As a preferred embodiment, the first frame is provided with a first insertion hole for mounting with a hinge.

[0009] As a preferred embodiment, a first notch is provided around the periphery of the first socket.

[0010] As a preferred embodiment, the second frame has a second insertion hole for mounting with a hinge.

[0011] As a preferred embodiment, a second notch is provided around the periphery of the second socket.

[0012] As a preferred embodiment, the first frame extends outward with a first extension portion. After the first frame is assembled and fixed to one of the boxes of the suitcase, the first extension portion fits against the inner wall of one of the boxes of the suitcase.

[0013] As a preferred embodiment, the second frame extends outward with a second extension portion. After the second frame is assembled and fixed to the other box of the suitcase, the second extension portion fits against the inner wall of the other box of the suitcase.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: When the first and second frames are engaged, the third explosion-proof part extends into the first slot, and the second explosion-proof part extends into the second slot. Furthermore, the third explosion-proof part is adapted to the first explosion-proof part, and the fourth explosion-proof part is adapted to the second explosion-proof part. This ensures that when the luggage frame structure is subjected to a large outward force, the first and third explosion-proof parts interfere with each other, maintaining the engagement of the first and second frames. If the first and third explosion-proof parts are damaged, the second and fourth explosion-proof parts interfere with each other, continuing to maintain the engagement of the first and second frames, effectively preventing the luggage from bursting open.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments: Attached Figure Description Figure 1 This is a cross-sectional view of a preferred embodiment of the present invention.

[0017] Please refer to Figure 1 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a first frame 10 and a second frame 20 that can cooperate with each other.

[0018] The first frame 10 is annular and fits into one of the compartments of the suitcase. The first frame 10 has a first explosion-proof part 11 and a second explosion-proof part 12, with a first groove 101 formed between the first explosion-proof part 11 and the second explosion-proof part 12. In this embodiment, the end of the first explosion-proof part 11 has a first hook 111, and the end of the second explosion-proof part 12 has a third hook 121. Additionally, the first frame 10 has a first insertion hole 13 for mounting with a hinge. A first notch 131 is provided around the periphery of the hole 13. Specifically, one end of the hinge is inserted into the first hole 13 for fixation, and the other end of the hinge is connected and fixed with the hinge of the inner lining of the suitcase, which effectively prevents the lining from falling off and solves the problem that the lining is not firmly attached with double-sided tape and the lining is easy to fall off. In addition, the first frame 10 extends outward with a first extension 14. After the first frame 10 is assembled and fixed to one of the suitcases, the first extension 14 fits against the inner wall of one of the suitcases.

[0019] The second frame 20 is annular and fits into another compartment of the suitcase. The second frame 20 has a third explosion-proof part 21 and a fourth explosion-proof part 22. The third explosion-proof part 21 extends into the first slot 101 and is fitted with the first explosion-proof part 11. The fourth explosion-proof part 22 is fitted with the second explosion-proof part 12. A second slot 201 is formed between the third explosion-proof part 21 and the fourth explosion-proof part 22. The aforementioned second explosion-proof part 12 extends into the second slot 201. In this embodiment, the end of the third explosion-proof part 21 has a second hook 211, which is adapted to the first hook 111; the end of the fourth explosion-proof part 22 has a fourth hook 221, which is adapted to the third hook 121; in addition, the second frame 20 is provided with a second insertion hole 23 for mounting with a hinge, and a second notch 231 is provided around the second insertion hole 23. Specifically, one end of the hinge is inserted into the second insertion hole 23 for fixation, and the other end of the hinge is connected and fixed to the hinge of the inner lining of the suitcase, which effectively prevents the lining from falling off and solves the problem of the lining falling off due to the unreliable double-sided adhesive used in the past; and the second frame 20 extends outward with a second extension 23. After the second frame 20 is assembled and fixed to the other box of the suitcase, the second extension 23 fits against the inner wall of the other box of the suitcase.

[0020] The key design feature of this utility model is: When the first and second frames are engaged, the third explosion-proof part extends into the first slot, and the second explosion-proof part extends into the second slot. Furthermore, the third explosion-proof part is adapted to the first explosion-proof part, and the fourth explosion-proof part is adapted to the second explosion-proof part. This ensures that when the luggage frame structure is subjected to a large outward force, the first and third explosion-proof parts interfere with each other, maintaining the engagement of the first and second frames. If the first and third explosion-proof parts are damaged, the second and fourth explosion-proof parts interfere with each other, continuing to maintain the engagement of the first and second frames, effectively preventing the luggage from bursting open.

[0021] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
