Description

Technical Field

[0001] This utility model relates to the field of travel bags, and more particularly to a travel bag with adjustable space. Background Technology

[0002] Travel bags are essential containers for carrying personal belongings when traveling. They include various styles such as rolling suitcases and backpacks. Adjustable travel bags have significant advantages. They can flexibly adjust the internal space according to the length of the trip and the number of items carried, avoiding the need to prepare multiple bags for different trips. After shopping on the trip, the space can be expanded to accommodate additional items, solving the problem of insufficient space. They can also make full use of the internal space of the bag according to the actual number of items, reducing the space occupied by the bag. Some products adopt a modular design, which allows for the classification and storage of items when adjusting the space, making it more convenient to access items.

[0003] Existing adjustable-space luggage mainly relies on three methods to achieve space adjustment: telescopic, folding, and expansion. Telescopic luggage often uses multi-section hard shells or telescopic frames, with each section connected by rails and sliders, and vertical or horizontal space adjustment achieved through positioning and locking devices. Folding luggage usually uses foldable frames, such as aluminum alloy "X"-shaped frames, combined with control strips and accordion-style waterproof covers or flexible shells. The size of the luggage can be changed by adjusting the degree of folding of the frame. Expandable luggage has a hidden expansion layer, which can be opened as needed using zippers, buckles, and other connectors to increase the luggage's volume.

[0004] While adjustable-space suitcases offer users a flexible storage experience thanks to their unique design, the design flaws of the pull handle significantly impact their practicality during actual use. During travel, suitcases inevitably encounter collisions and pressure. Once the pull handle is damaged, such as breaking or becoming stuck and unable to extend, users will find it difficult to easily drag the suitcase. This is especially true when carrying a large amount of luggage or on long journeys. Without the pull handle's assistance, users are forced to carry the suitcase by hand, which is not only physically demanding but also severely disrupts the travel rhythm, causing numerous inconveniences.

[0035] Specifically, when the pull rod is damaged and needs to be replaced, first, the user holds the lever 8 and slowly pulls it outward. In this process, the fixed column 7 will gradually come out of the fixed slot 13 under the action of tension. At this time, the pull rod box 10 is successfully unlocked. Then, the user holds the handle 11 with his hand and lifts the pull rod box 10 upward smoothly. With the increase of force, the limiting block 6 will also smoothly come out of the pull rod box 10. In this way, the damaged pull rod box 10 can be easily removed. Then, take out the brand new pull rod box 10 and slide it into the box body 1. In this process, carefully align the bottom with the position of the limiting block 6 to ensure that the limiting block 6 can completely and smoothly enter the pull rod box 10. Finally, release the lever 8. At this time, the fixed column 7 will be reinserted into the fixed slot 13 under the action of the spring 9, firmly fixing the pull rod box 10. Thus, the replacement work of the pull rod box 10 is successfully completed.

[0036] With reference to Figure 4 and Figure 5 , the outer wall of the box body 1 is provided with a plurality of connecting grooves 14 for accommodating the connecting strips 16 and the limiting strips 17. The outer wall of the box body 1 is slidingly connected with a plurality of protective corners 15 for preventing the corners of the box body 1 from being damaged. The inner wall of each protective corner 15 is fixedly connected with a connecting strip 16 for connecting the limiting strip 17.

The outer wall of each limiting strip 17 is slidingly connected to the inner part of the connecting groove 14.

[0037] Specifically, when the protective corner 15 is damaged due to accidental collision during daily use of the luggage, it needs to be replaced in time. First, the user needs to hold the protective corner 15 and move it outward slowly with uniform force. In this process, the displacement of the protective corner 15 outward will cause the inner wall of the box body 1 to press the fixed pin 18, and after the fixed pin 18 is stressed, it will gradually shrink into the inside of the limiting strip 17. At this time, the protective corner 15 is successfully unlocked. After unlocking, continue to pull the protective corner 15 outward. With the continuous action of the force, the limiting strip 17 will gradually come out from the inside of the connecting groove 14, and then the damaged protective corner 15 will be disassembled. Subsequently, a brand new protective corner 15 is taken out from the spare parts, and the connecting strip 16 and the limiting strip 17 on the inner wall of the protective corner 15 are carefully aligned with the corresponding connecting groove 14 position on the box body 1. After confirming that there is no error, the protective corner 15 is gently pushed to make the connecting strip 16 and the limiting strip 17 smoothly slide into the inside of the connecting groove 14. In the process of pushing, the inner wall of the box body 1 will press the fixed pin 18 again, so that it shrinks into the inside of the limiting strip 17. When the connecting strip 16 and the limiting strip 17 slide into the deepest part of the connecting groove 14, the fixed pin 18 will quickly pop out under the action of the elasticity of the spring 2 0, and accurately be clamped into the preset position, so as to firmly fix the protective corner 15 on the surface of the box body 1. Thus, the replacement work of the protective corner 15 is successfully completed.

[0038] Working principle: in the process of using the space adjustable travel luggage, when the storage space inside the box body 1 needs to be extended, the zipper 5 is pulled open to unlock the hidden space inside, and the extension of the space inside the box body 1 is completed.

Then hold the handle 11 and lift the pull rod box 10 upwards, so that the limiting block 6 is pulled out from the inside of the pull rod box 10, and then the pull rod box 10 is disassembled. Then take out the new pull rod box 10, slide it into the inside of the box body 1, and align the position of the bottom with the position of the limiting block 6, so that the limiting block 6 completely enters the inside of the pull rod box 10. Then release the lever 8 so that the fixed column 7 reenters the inside of the fixed slot 13, and the pull rod box 10 is completely fixed, and the replacement of the pull rod box 10 is completed. When the protective corner 15 needs to be replaced due to damage, first hold the protective corner 15 and move it outward, so that the fixed pin 18 is pressed by the inner wall of the box body 1 and is retracted into the inside of the limiting strip 17, and then the protective corner 15 is unlocked. Then continue to pull the protective corner 15 outward to make the limiting strip 17 completely come out of the inside of the connecting slot 14, and the protective corner 15 is disassembled. Then take out the new protective corner 15, align the connecting strip 16 and the limiting strip 17 on the inner wall with the corresponding connecting slot 14 position, and then slide the connecting strip 16 and the limiting strip 17 into the inside of the connecting slot 14, so that the fixed pin 18 is pressed by the inner wall of the box body 1 and is retracted into the inside of the limiting strip 17. When the connecting strip 16 and the limiting strip 17 slide into the inside of the connecting slot 14, the fixed pin 18 is pulled out under the action of the spring 20, and the protective corner 15 is completely fixed on the surface of the box body 1. Thus, the replacement of the protective corner 15 is completed.
