[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Example 1

[0026] Please refer to Figure 1Embodiment 1 of the present invention provides a side-by-side expandable luggage, including a first box body 1, a second box body 2, a side wall folding cloth 3, two box body expansion zippers 4 and a reinforcement ring 5. The following is a detailed description of the various components of this embodiment with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the side wall folding cloth 3 can be arranged in a square shape, one edge of the side wall folding cloth 3 is connected to the edge of the first box body 1, and the other edge of the side wall folding cloth 3 is connected to the edge of the second box body 2. The side wall folding cloth 3 can be made of various flexible fabrics or leather materials.

[0028] like Figure 1 and Figure 2 As shown, the two box expansion zippers 4 are arranged side by side between the first box body 1 and the second box body 2 and are located on the outer surface of the side wall folding cloth 3. The two box expansion zippers 4 can include a first chain tooth belt 41, a second chain tooth belt 42 and a box expansion zipper head 43. The box expansion zipper head 43 is movably installed between the first chain tooth belt 41 and the second chain tooth belt 42. The first chain tooth belt 41 and the second chain tooth belt 42 are respectively sewn to the side wall folding cloth. The head ends of the first chain tooth belt 41 and the second chain tooth belt 42 are both installed in the middle position of one side of the side wall folding cloth. The belt bodies of the first chain tooth belt 41 and the second chain tooth belt 42 are respectively arranged on the outer surface of the side wall folding cloth from the middle position of one side of the side wall folding cloth to both sides. The tail ends of the first chain tooth belt 41 and the second chain tooth belt 42 exceed the end fixed position of the head end of the first chain tooth belt 41 and the second chain tooth belt 42 or are close to the end fixed position of the head end of the first chain tooth belt 41 and the second chain tooth belt 42.

[0029] like Figure 1 and Figure 2 As shown, the reinforcement ring 5 can be installed on the outer surface or inner surface of the side wall folding cloth and located between two adjacent box expansion zippers 4. During specific manufacturing, the reinforcement ring 5 can preferably be set as a steel wire reinforcement ring. Of course, according to actual needs, the ring body made of other hard materials can also be used.

[0030] A reinforcement ring is added between two adjacent box expansion zippers, which is conducive to the installation and use of the box expansion zippers arranged side by side, and can also reinforce the side wall folding cloth.

[0031] like Figure 1 and Figure 2 As shown, when the two box expansion zippers 4 are fully opened, the first box 1 and the second box 2 are away from each other, and the side wall folding cloth 3 can be fully unfolded. At this time, the bag is in the maximum expansion state (secondary expansion).

[0032] like Figure 3 and Figure 4As shown, when one of the box body expansion zippers 4 is opened and the other box body expansion zipper 5 is closed, the bag is in a first-level expansion state, and the expansion capacity is reduced.

[0033] like Figure 5 and Figure 6 As shown, when the two box expansion zippers 4 are closed, the first box 1 and the second box 2 are brought closer to each other, and the bag is in a non-expanded state.

[0034] like Figure 1 As shown, the front of the second box body 2 is provided with a front opening communicating with the interior thereof, and a front cover 9 is provided at the position of the front opening of the second box body 2. The second box body 2 and the front cover 9 are connected via a front cover opening and closing connector. In this embodiment, the front cover opening and closing connector can preferably be configured as a front cover opening and closing zipper 10. Of course, in other embodiments, it can also be configured as a lock, buckle, combination lock, or other opening and closing connector, and the present embodiment is not limited thereto.

[0035] Example 2

[0036] The second embodiment of the present invention provides a side-by-side expandable luggage, which makes the following improvements on the basis of the above-mentioned first embodiment:

[0037] like Figure 7 and Figure 8 As shown, the inner wall of the luggage cavity formed by the first box body 1, the side wall folding cloth 3 and the second box body 2 can be covered with a lining 7, and the side of the lining 7 is connected to a surrounding lining expansion zipper 8, the lining expansion zipper 8 can include a third chain tooth belt 81, a fourth chain tooth belt 82 and a lining expansion zipper head 83, the lining expansion zipper head 83 is movably installed between the third chain tooth belt 81 and the fourth chain tooth belt 82, the third chain tooth belt 81 and the fourth chain tooth belt 82 are respectively sewn to the lining, and the heads of the third chain tooth belt 81 and the fourth chain tooth belt 82 are The ends are both installed in the middle position of one side of the lining, the belt body of the third chain tooth belt 81 is arranged in a circle on the outer surface of the lining from the middle position of one side of the lining toward the first box body, and the belt body of the fourth chain tooth belt 82 is arranged in a circle on the outer surface of the lining from the middle position of one side of the lining toward the second box body, and the tail ends of the third chain tooth belt 81 and the fourth chain tooth belt 82 exceed the end fixed position of the head end of the third chain tooth belt 81 and the fourth chain tooth belt 82 or are close to the end fixed position of the head end of the third chain tooth belt 81 and the fourth chain tooth belt 82.

[0038] When the third chain tooth tape 81 and the fourth chain tooth tape 82 of the lining expansion zipper 8 are fully closed, the lining portion located between the third chain tooth tape 81 and the fourth chain tooth tape 82 can be folded and stored, and the head ends of the third chain tooth tape 81 and the fourth chain tooth tape 82 can be buried inside the tail ends of the third chain tooth tape 81 and the fourth chain tooth tape 82.

[0039] When the third and fourth chain tooth tapes 81 and 82 of the lining expansion zipper 8 are fully opened, the lining can be expanded in the thickness direction of the bag, so that it can better cooperate with the bag body for expansion.

[0040] Of course, in other embodiments, in order to enable the lining to achieve multi-level expansion, the side of the lining 7 can also be provided with at least two lining expansion zippers 8 arranged side by side, such as Figure 9 As shown, two lining expansion zippers 8 may be preferably provided.

[0041] To sum up, the structural design of the utility model is reasonable. When the luggage needs to be expanded, different box expansion zippers can be opened to enable the luggage to achieve at least two levels of expansion. The expansion capacity of the luggage can be freely selected by the user, which is flexible and easy to use.

[0042] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
