The mother-and-child suitcase has two suitcases of different sizes, and is favored by consumers for its strong storage function and flexibility.

[0003] Currently, the large suitcase of the mother-and-child suitcase is attached with wheels and a handle. Usually, the small suitcase is tied to the large suitcase and dragged together when walking. However, when used separately, the small suitcase can only be carried by hand. Among the consumer groups of mother-and-child suitcases, women often account for the majority. They are used to putting important things and daily necessities in their small handbags, so the small suitcase of the mother-and-child suitcase will be left unused. When the large and small suitcases must be used separately in some occasions, the small suitcase can only be held in the hand, which is very inconvenient to have an extra bag in the hand.

[0004] In view of this, designing a carry-on suitcase with a simple structure and a wide customer group is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide a carry-on suitcase. The carry-on suitcase realizes the carry-on use of two suitcases by horizontally installing the second box body on the first box body through buckling of a sub-buckle and a mother-buckle. When the sub-buckle and the mother-buckle are disassembled, the first suitcase and the second suitcase can become two independent suitcases for separate use. The structure is simple and more suitable for the needs of the male consumer group, and has a wider customer group than the existing mother-and-child suitcase.

Specific embodiments

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] As Figures 1 to 7 shown, a carrier-type suitcase includes a first suitcase 1 and a second suitcase 2. The first suitcase 1 includes a first box body 11, a first roller 12 provided at the bottom of the first box body 11, a first pull rod 13 provided on the side of the first box body 11, and a female buckle 14. When the first pull rod 13 is stretched, it can extend to the upper part of the first box body 11. The second suitcase 2 includes a second box body 21 and a male buckle 24, a second roller 22 provided at the bottom of the second box body 21, a second pull rod 23 provided on the same side of the second box body 21, and a pull rod lock 25. When the second pull rod 23 is stretched, it can extend to the upper part of the second box body 21. When the second pull rod 23 is retracted, it can be locked by the pull rod lock 25 to form a closed cavity with the second box body 21. The male buckle 24 is provided on the side of the second box body 21 and matches the female buckle 14. The second suitcase 2 can be horizontally installed on the first suitcase 1 by matching and fastening the female buckle 14 and the male buckle 24. At this time, when the first pull rod 13 is stretched, it can pass through the formed closed cavity and extend to the upper part of the second box body 21.

[0027] In this embodiment, the portable suitcase is horizontally mounted on the first suitcase body 11 by matching and fastening the male buckle 14 and the female buckle 24. When two suitcases are used in a mounted manner simultaneously, the second pull rod 23 and the pull rod lock 25, which are both provided on the same side of the second suitcase body 21, form a closed cavity for the first pull rod 13 to pass through after being locked, so as to ensure that the second suitcase 2 can be stably mounted on the first suitcase 1. When the two suitcases do not need to be used in a mounted manner, the matching male buckle 24 and female buckle 14 are loosened, and the second pull rod 23 on the second suitcase 2 is stretched at the same time, thus realizing the independent use of the first suitcase 1 and the second suitcase 2. It has a simple structure and can meet the needs of male consumer groups, and has a wider customer group than the existing alphabet suitcases. In this embodiment, when the first suitcase 1 and the second suitcase 2 are used in a mounted manner, the second pull rod 23 on the second suitcase 2 is in a retracted state, and the bottom end of the second pull rod 23 is locked with the pull rod lock 25 and forms a closed cavity for the first pull rod 13 to pass through with the second suitcase body 21.

[0028] In this embodiment, the first pull rod 13 and the female buckle 14 are respectively provided on two sides of the first suitcase body 11, and the second pull rod 23 and the pull rod lock 25 are both provided on the same side of the second suitcase body 21. When the second suitcase body 21 is installed on the first suitcase body 11, the female buckle 14 and the male buckle 24 are on the same side and can be matched and fastened. At this time, the second pull rod 23 contracts to the side of the second suitcase body 21. When the second suitcase 2 is used independently, the second pull rod 23 can be stretched from the side of the second suitcase body 21 to the upper part of the second suitcase body 21 to drag the whole suitcase forward. In other embodiments, the first pull rod 13 and the female buckle 14 can be provided on the same side of the first suitcase body 11.

[0029] As Figures 1 to 4 shown, the first pull rod 13 is provided at the rear side of the first suitcase body 11, and the female buckle 14 is provided on the left side or (and) the right side of the first suitcase body 11.

[0030] As Figure 5 、 Figure 6 、 Figure 7 shown, the second pull rod 23 is provided at the rear side of the second suitcase body 21, and the male buckle 24 is provided on the upper side or (and) the lower side of the second suitcase body 21 and is matched with the female buckle 14.

[0031] In this embodiment, the first pull rod 13 is arranged at the rear side of the first box body 11, the second pull rod 23 is arranged at the rear side of the second box body 21, the female buckle 14 is arranged on the left and right sides of the first box body 11, and the male buckle 24 is arranged on the upper and lower sides of the second box body 21 and matches with the female buckle 14. When the first suitcase 1 and the second suitcase 2 are used in combination, the second pull rod 23 is retracted and the male buckle 24 arranged on the upper and lower sides of the second box body 21 matches and fastens with the female buckle 14 arranged on the left and right sides of the first box body 11, realizing the horizontal placement of the second suitcase 2 on the upper side of the first suitcase 1. In other embodiments, the male buckle 24 can be arranged only on the upper side or the lower side of the second box body 21, and the female buckle 14 is correspondingly arranged on the left side or the right side of the first box body 11, as long as it is ensured that the second suitcase 2 can be stably horizontally placed on the first suitcase 1 when used in combination.

[0032] As Figure 3 , Figure 4 shown, the first pull rod 13 includes a first telescopic rod 131 and a second telescopic rod 132. The first telescopic rod 131 can be stretched to the upper part of the first box body 11, and the second telescopic rod 132 can be stretched to the upper part of the second box body 21 installed on the first box body 11.

[0033] As Figure 3 , Figure 4 shown, the first telescopic rod 131 is sleeved on the second telescopic rod 132.

[0034] In this embodiment, the first pull rod 13 includes a first telescopic rod 131 and a second telescopic rod 132. The first telescopic rod 131 can be stretched to the upper part of the first box body 11, and the second telescopic rod 132 can be stretched to the upper part of the second box body 21 installed on the first box body 11. The first telescopic rod 131 is sleeved on the second telescopic rod 132. When the first suitcase 1 is used alone, the first telescopic rod 131 can be stretched to the upper part of the first box body 11; when the second suitcase 2 is used in combination with the first suitcase 1, the second telescopic rod 132 can be stretched to the upper part of the second box body 21; at the same time, when the first telescopic rod 131 is sleeved on the second telescopic rod 132, the installation space of the first pull rod 13 is reduced to a certain extent, and the structure is simpler and more beautiful.

[0035] As Figure 6 , Figure 7 shown, a U-shaped groove 26 is arranged at the rear side of the second box body 21, and a pull rod lock 25 is arranged at the lower side of the U-shaped groove 26. When the second pull rod 23 is retracted, the bottom end of the second pull rod 23 can be locked with the pull rod lock 25 and form a closed cavity with the second box body 21. In this embodiment, by arranging the U-shaped groove 26 at the rear side of the second box body 21, when the second suitcase 2 is horizontally placed on the first suitcase 1, the first pull rod 13 can quickly pass through the closed cavity formed by the second pull rod 23 and the second box body 21, improving the combination efficiency of the user.

[0036] As Figures 1 to 7 shown, there are four first rollers 12 and four second rollers 22. The four first rollers 12 are respectively arranged at the four corners of the bottom of the first box body 11, and the four second rollers 22 are respectively arranged at the four corners of the bottom of the second box body 21. In this embodiment, by respectively arranging the corresponding first rollers 12 and second rollers 22 at the four corners of the bottom of the first box body 11 and the second box body 21, it can effectively ensure that the first suitcase 1 and the second suitcase 2 can be stably placed on the horizontal ground whether they are used in a carried mode or alone, reducing the time for consumers to support the box and improving the consumer experience.

[0037] As Figures 1 to 7 shown, the first rollers 12 and the second rollers 22 are 360° rotatable universal casters. In this embodiment, the first rollers 12 and the second rollers 22 are both 360° rotatable universal casters. By setting 360° rotatable universal casters, it is ensured that the first suitcase 1 and the second suitcase 2 can turn in any direction whether they are used in a carried mode or alone, greatly improving the consumer experience.

[0038] As Figures 1 to 7 shown, the first pull rod 13 and the second pull rod 23 are aluminum alloy telescopic rods. In this embodiment, the first pull rod 13 and the second pull rod 23 are both aluminum alloy telescopic rods, effectively ensuring the usage experience and service life of the first pull rod 13 and the second pull rod 23.

[0039] As Figure 1 、 Figure 2 shown, the first suitcase 1 and the second suitcase 2 are of the same size. In this embodiment, the first suitcase 1 and the second suitcase 2 are of the same volume, effectively avoiding the embarrassing situation where when one of the suitcases is idle, one can only hold the idle suitcase in hand. The idle suitcase can be used alone by setting the pull rod and rollers on it.
