Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a foldable portable luggage. Background Technology

[0002] In today's fast-paced life, people travel more frequently, whether for business trips, vacations, or everyday shopping, and bags are indispensable. For travelers, a versatile and easy-to-carry bag is crucial. Foldable portable bags have emerged to meet this need, aiming to satisfy diverse needs in different scenarios and provide greater convenience for travel.

[0003] Currently, most bags on the market use simple opening and closing mechanisms, connecting various parts of the bag with zippers to store items. Their internal space layout is fixed, relying on compartments and pockets of fixed sizes for item organization. For carrying, they primarily rely on wheels fixed to the bottom and a retractable handle for easy movement.

[0004] However, these traditional bags have some drawbacks. Their space is fixed, lacking flexibility and difficult to adjust to the quantity and volume of items. When carrying a lot of items, they often don't fit everything. Even if items are squeezed in, loosely placed items will move around inside, wasting space and making full use of the limited space. This also easily leads to items squeezing and colliding with each other, causing damage, especially to easily wrinkled items like clothing, which will become creased and affect the user experience. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-assembly river flood control retaining wall, which aims to improve the problem that traditional bags have fixed space and poor flexibility, often resulting in insufficient space. Even if items are squeezed in, loosely placed items will shake inside the bag, causing wasted space.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable portable bag, comprising an outer shell, an outer shell two disposed on the outer wall of the outer shell, a pull rod slidably connected to the inner wall of the outer shell, a folding component disposed on one side of the outer wall of the outer shell, a resting component disposed on the inner wall of the outer shell, a zipper fixedly connected to one side of the outer wall of the outer shell, and universal wheels fixedly connected to the lower surfaces of the outer shell and the outer shell two;

[0007] The folding assembly includes a folding plate, the inner wall of which is fixedly connected to one side of the outer wall of the first outer shell. A second support block is fixedly connected to the outer wall of the second outer shell. A slide cylinder is fixedly connected to the inner wall of the second support block. The inner wall of the slide cylinder is slidably connected to a slide column. A first spring is fixedly connected to the outer wall of the slide cylinder. A first support block is fixedly connected to the outer wall of the first outer shell. A first rotating shaft is fixedly connected to one side of the outer wall of the first outer shell. A fixed rod is rotatably connected to the outer wall of the first rotating shaft. A first fixed shaft is fixedly connected to one side of the outer wall of the second outer shell.

[0008] Furthermore, the resting assembly includes a seat plate, the outer wall of which is rotatably connected to the inner wall of the outer shell, a second rotating shaft is fixedly connected to the inner wall of the seat plate, a second spring is fixedly connected to the inner wall of the outer shell, a second fixed shaft is fixedly connected to one end of the second spring, a third rotating shaft is rotatably connected to the inner wall of the seat plate, a first support leg is fixedly connected to the outer wall of the third rotating shaft, and a telescopic leg is threadedly connected to the inner wall of the first support leg.

[0009] Furthermore, the two ends of the second rotating shaft are rotatably connected to the inner wall of the outer casing, and the second rotating shaft is used to drive the seat plate to rotate.

[0010] Furthermore, the outer wall of the second fixed shaft is slidably connected to the inside of the seat plate, and the second fixed shaft is used to limit the position of the seat plate.

[0011] Furthermore, the first support leg and the telescopic leg are rotatably connected inside the seat plate, and the first support leg and the telescopic leg are used to support the seat plate.

[0012] Furthermore, the outer wall of the zipper is fixedly connected to the inner wall of the second outer shell, and the zipper is used to connect the first outer shell and the second outer shell.

[0013] Furthermore, the inner wall of the fixing rod is slidably connected to the outer wall of the rotating shaft, and the fixing rod is used to limit the folding plate.

[0014] Furthermore, one end of the folding plate is fixedly connected to the outer wall of the outer shell, and the folding plate is used to expand the space.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by pulling the outer shell II outward, the folding plate unfolds accordingly. The sliding column slides and stretches the spring I inside the sliding cylinder. After unfolding to the correct position, the fixing rod is rotated to limit the movement. When storing, rotating the fixing rod causes the spring I to contract and drive the outer shell II and the folding plate back to their original positions. This solves the problem of traditional bags having fixed space, poor flexibility, and often not being able to fit everything in. Even if items are squeezed in, loosely placed items will shake inside the bag, causing wasted space. This invention achieves the goal of flexibly increasing the storage space of bags, meeting people's needs to carry more items, improving space utilization, keeping clothes relatively flat, and making it easier and more convenient for people to carry bags.

[0017] 2. In this utility model, the seat plate is rotated through the second pivot to rotate it out of the first outer shell. Then the support legs are unfolded and the length of the telescopic legs is adjusted. After use, the telescopic legs and support legs are retracted first, and then the seat plate is rotated back into the first outer shell. It is limited by the second fixed pivot, so that it can be quickly assembled into a simple stool when needed, providing a resting place for users and improving the comfort of travel. When not in use, it can be stored without taking up extra space, which is both practical and convenient. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model is provided: a foldable portable bag, including an outer shell 1, an outer shell 2 on the outer wall of the outer shell 1, a pull rod 4 slidably connected to the inner wall of the outer shell 1, a folding component on one side of the outer wall of the outer shell 1 for expanding the bag space, a rest component on the inner wall of the outer shell 1 for improving people's comfort, a zipper 3 fixedly connected to one side of the outer wall of the outer shell 1, and universal wheels 5 fixedly connected to the lower surfaces of the outer shell 1 and the outer shell 2.

[0027] The folding assembly includes a folding plate 9, the inner wall of which is fixedly connected to one side of the outer wall of the outer shell 1. A support block 16 is fixedly connected to the outer wall of the outer shell 2. A slide cylinder 17 is fixedly connected to the inner wall of the support block 16. A slide column 19 is slidably connected to the inner wall of the slide cylinder 17. A spring 18 is fixedly connected to the outer wall of the slide cylinder 17. A support block 10 is fixedly connected to the outer wall of the outer shell 1. A rotating shaft 6 is fixedly connected to one side of the outer wall of the outer shell 1. A fixing rod 7 is rotatably connected to the outer wall of the rotating shaft 6. A fixing shaft 8 is fixedly connected to one side of the outer wall of the outer shell 2.

[0028] Specifically, by pulling the outer shell 2 outward, the folding plate 9 is unfolded. When unfolded, the sliding column 19 slides inside the sliding cylinder 17 and stretches the spring 18. After unfolding to the correct position, the rotating fixing rod 7 is locked at the upper limit of the fixing shaft 8 to maintain the extended state. When retracting, the rotating fixing rod 7 disengages from the fixing shaft 8, and the elastic force of the spring 18 causes the sliding column 19 to retract, thereby resetting the outer shell 2 and the folding plate 9.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The resting component includes a seat plate 11. When the outer shell 2 is pulled outward, the folding panel 9 unfolds, increasing the storage capacity of the bag and meeting the need to carry more items. The outer wall of the seat plate 11 is rotatably connected to the inner wall of the outer shell 1. A pivot 12 is fixedly connected to the inner wall of the seat plate 11. A spring 20 is fixedly connected to the inner wall of the outer shell 1. One end of the spring 20 is fixedly connected to a fixed shaft 13. A pivot 3 21 is rotatably connected to the inner wall of the seat plate 11. A support leg 14 is fixedly connected to the outer wall of the pivot 3 21. A telescopic leg 15 is threadedly connected to the inner wall of the support leg 14. When the seat plate 11 is rotated out, the support leg 14 is rotated out, and its length is adjusted by rotating the telescopic leg 15. Both support the seat plate 11 together, ensuring the stability of the seat plate 11. The base supports the user's weight and meets the user's rest needs. The two ends of the pivot 12 are rotatably connected to the inner wall of the outer shell 1. The pivot 12 is used to drive the seat plate 11 to rotate. The outer wall of the fixed pivot 13 is slidably connected to the inside of the seat plate 11. The fixed pivot 13 is used to limit the position of the seat plate 11. The support leg 14 and the telescopic leg 15 are rotatably connected to the inside of the seat plate 11. The support leg 14 and the telescopic leg 15 are used to support the seat plate 11. The outer wall of the zipper 3 is fixedly connected to the inner wall of the outer shell 2. The zipper 3 is used to connect the outer shell 1 and the outer shell 2. The inner wall of the fixed rod 7 is slidably connected to the outer wall of the pivot 6. The fixed rod 7 is used to limit the position of the folding plate 9. One end of the folding plate 9 is fixedly connected to the outer wall of the outer shell 2. The folding plate 9 is used to expand the space.

[0030] Specifically, the seat plate 11 is rotated around the pivot 12 to move out of the outer shell 1. During this process, the fixed pivot 13 slides inside the seat plate 11, and the spring 20 retracts. After the seat plate 11 moves out, the support leg 14 is rotated to move out of the seat plate 11. Then, the telescopic leg 15 is rotated to adjust the length. The two support the seat plate 11 together for people to rest. After use, the telescopic leg 15 is first rotated back, then the support leg 14 is rotated back to the inside of the seat plate 11. Finally, the seat plate 11 is rotated back to the inner wall of the outer shell 1, and the fixed pivot 13 is limited and fixed by the spring 20.

[0031] Working principle: When a foldable portable bag is needed, to expand the bag's space, pull the outer shell 2 outwards. The outer shell 2 drives the folding plate 9 to unfold. During the unfolding process, the sliding column 19 slides inside the sliding cylinder 17, while simultaneously stretching the spring 18. When the folding plate 9 is unfolded to the appropriate position, rotate the fixing rod 7 so that one end of it is locked onto the fixing shaft 8, thereby limiting the folding plate 9 and maintaining its expanded state. To fold the folding plate 9, first rotate the fixing rod 7 to disengage it from the fixing shaft 8. Under the elastic force of the spring 18, the sliding column 19 retracts inside the sliding cylinder 17, driving the outer shell 2 and the folding plate 9 back to their initial positions. Furthermore, the spring 18 can compress the clothes inside the outer shell 1 and the outer shell 2, thus expanding the internal space again.

[0032] Furthermore, when the stool is needed, the seat plate 11 is rotated around the pivot 12 to rotate it out of the inside of the outer shell 1. During the rotation, the fixed pivot 13 slides inside the seat plate 11 through the inclined plane. At this time, the spring 20 retracts. After the seat plate 11 rotates out to the correct position, the support leg 14 is rotated to rotate it out of the inside of the seat plate 11. Then, the telescopic leg 15 is rotated according to actual needs to adjust its length. The support leg 14 and the telescopic leg 15 together support the seat plate 11 for people to rest. After use, the telescopic leg 15 is first rotated back up, and then the support leg 14 is rotated back to the inside of the seat plate 11. Finally, the seat plate 11 is rotated around the pivot 12 to return it to the inner wall of the outer shell 1. The fixed pivot 13 limits and fixes the seat plate 11 under the rebound action of the spring 20.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
