Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] refer to Figures 1 to 4 The present invention provides a suitcase, comprising: a vehicle body 1 and a suitcase 2, wherein the suitcase 2 is detachably connected to the top of the vehicle body 1; the suitcase 2 includes a telescopic bracket 3 and an expandable fabric tube 4, wherein the expandable fabric tube 4 is detachably fitted onto the telescopic bracket 3.
[0024] The telescopic bracket 3 includes a base plate 5, support sleeves 6, and telescopic rods 7. Support sleeves 6 are connected to each of the four corners of the base plate 5. The telescopic rods 7 are inserted into the support sleeves 6, and both the support sleeves 6 and the telescopic rods 7 have corresponding screw holes. The two corresponding screw holes are locked together by bolts. The internal space of the telescopic bracket 3 can be adjusted by adjusting the length of the telescopic rods 7 inserted into the support sleeves 6.
[0025] The base plate 5 includes a first rigid board layer 8 and a second rigid board layer 9. The side of the first rigid board layer 8 away from the second rigid board layer 9 is connected to the bottom end of the support sleeve 6 via a soft cloth layer 10. The side of the second rigid board layer 9 away from the first rigid board layer 8 is also connected to the bottom end of the support sleeve 6 via a soft cloth layer 10. The first rigid board layer 8 and the second rigid board layer 9 are connected by the soft cloth layer 10. When the box is not in use, the expandable cloth tube can be removed first, and then the first and second cardboard pieces can be folded together via the middle soft cloth layer for storage.
[0026] The technical solution is further optimized, with a male buckle 11 connected to the top of one telescopic rod 7, and a female buckle 12 adapted to the male buckle rotatably connected to the top of the other telescopic rod 7. The male buckle 11 is inserted into the female buckle 12 and locked by rotation, thereby realizing the folding and storage of the telescopic bracket, which will not be easily opened.
[0027] To further optimize the technical solution, a first magnetic sheet is embedded at the bottom of the support sleeve 6, and a second magnetic sheet 13, corresponding to the position of the first magnetic sheet but with opposite magnetic poles, is embedded at the top of the vehicle body 1. The support sleeve 6 and the vehicle body 1 are detachably connected through the magnetic attraction between the first magnetic sheet and the second magnetic sheet 13.
[0028] To further optimize the technical solution, the expandable fabric tube 4 is provided with multiple folded fabric layers 14 spaced longitudinally. Each folded fabric layer 14 has a matching zipper on its upper and lower sides. Closing the zippers folds the fabric layers, reducing their storage space. Opening the zippers unfolds the fabric layers, increasing their storage space. The size of the expandable fabric tube 4's storage space is adjusted to accommodate the internal space of the telescopic bracket 3. Additionally, openings corresponding to the telescopic rod are provided at the four corners of the top of the expandable fabric tube, and these openings are sealed with Velcro or zippers.
[0029] To further optimize the technical solution, storage bags are connected to both sides and the tail end of the expandable cloth tube, making it convenient to hold some small items.
[0030] To further optimize the technical solution, the vehicle body includes a support plate 15 and a handle 16. The handle 16 is installed at the front end of the support plate 15, and self-locking casters 17 are installed at the four corners of the bottom end of the support plate to facilitate the pushing of the vehicle body. Furthermore, the handle is equipped with straps to secure the telescopic rod on the box to the handle, ensuring a stable and reliable connection between the box and the vehicle body.
[0031] This utility model provides a suitcase with a telescopic bracket and an expandable fabric tube, both designed to be expandable or retractable to accommodate luggage of different sizes. It also allows for the separation of the vehicle body and the suitcase, with the upper suitcase providing effortless and space-saving storage, while the lower vehicle body facilitates efficient transport and avoids wasting resources. It can be used for needs such as delivering packages or grocery shopping. The telescopic bracket can be stored away when not in use, reducing space occupation. The expandable fabric tube is easy to disassemble, replace, and clean.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
