Description
TECHNICAL FIELD
[0001] The utility model relates to the field of luggage with climbing function, more specifically, it relates to a luggage with climbing function. BACKGROUND
[0002] In the field of luggage design, the realization of climbing function, disassembly and assembly convenience and structural stability are the key factors affecting the practicability of products, however, there are still many technical defects in the actual application of the luggage products on the current market, which not only affects the use experience, but also reduces the practical value of the products.
[0003] The first problem is that the functionality of the luggage is seriously insufficient, and the existing luggage in the prior art has obvious defects in functional design: first, the traditional luggage only has the basic flat sliding function and completely lacks the ability to deal with steps and other height differences; second, when encountering steps and other obstacles, the user can only carry the luggage by lifting; third, this limitation not only increases the physical burden of the user, but also may cause accidental risks due to heavy lifting, which not only reduces the practical value of the product, but also cannot meet the needs of modern users for convenient travel.
[0004] More prominent is that the disassembly and assembly convenience of the luggage has major defects, although some products adopt split design, but such design still has significant problems in actual use: first, the luggage body and the mounting frame are mostly integrated, lacking flexibility; second, even if the split design is adopted, the disassembly and assembly process still needs to use professional tools, increasing the operation complexity; third, the cumbersome disassembly and assembly steps not only waste time, but also increase the user's use burden, which not only affects the use efficiency of the product, but also reduces the practicability and adaptability of the luggage.
[0005] Most importantly, the structural stability of the luggage is seriously insufficient, although some products realize the split assembly function by increasing the connecting parts, but such design still has obvious defects: first, the stability of the connecting structure is poor and is easy to loosen due to external force; second, during the movement of the luggage, vibration and collision may cause displacement of the connecting part; third, the instability of the structure not only affects the use safety, but also may cause the connection between the luggage and the mounting frame to fail, which not only affects the use reliability of the product, but also may cause safety hazards.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a bag with a climbing function, which has the following features:
[0019] Beneficial effects:
[0020] 1. The climbing device, through the rational combination of mounting frame, wheels, and movable frame, constructs an efficient stair climbing system. The detachable connection between the mounting frame and the bag provides basic support for the overall structure. The movable frame, through the rotating connection with the mounting frame via bearings, ensures the flexibility of movement. The scientific arrangement of the three wheels provides stable support for climbing. The rubber sleeve design at the end of the mounting frame not only improves anti-slip performance but also enhances the operating feel. This innovative climbing structure, through the step-by-step contact between the wheels and the steps, combined with the rotating design of the movable frame, enables the bag to climb, effectively solving the problem that traditional bags cannot climb stairs.
[0021] 2. The quick-change device, through the precise cooperation of the mounting plate, fixing plate, quick-change sleeve, and rotating plate, constructs a convenient assembly and disassembly system. The detachable connection between the mounting plate and fixing plate and the bag provides basic support for assembly and disassembly. The quick-change sleeve ensures the accuracy of installation through the sliding cooperation between the guide strip and the quick-change rod guide groove. The rotating plate, through the rotation design of the shaft in the storage slot and the elastic action of the movable spring, realizes rapid assembly and disassembly operations. The fixed design of the side plate and bottom plate provides all-round support for the bag. This innovative quick-change mechanism enables the rapid assembly and disassembly of the bag and the mounting frame without the need for professional tools, effectively solving the problem of cumbersome assembly and disassembly of traditional bags.
[0022] 3. The locking mechanism, through the ingenious cooperation of the control sleeve, return plate, release block, and return rod, constructs a reliable limiting system. The sliding connection between the control sleeve and the quick-change sleeve provides the motion basis for the overall structure. The design of the return hole on the return plate and the return rod, through the preload of the return spring, ensures the reliability of the locked state. The inclined structure design of the release block and release groove, combined with the limiting mechanism of the top block, ensures the stability of the locked state through precise transmission. This multi-locking mechanism not only effectively prevents structural loosening caused by movement and vibration, but also ensures the reliability of the locking operation through precise transmission, solving the problem of loose connections that easily occur in traditional bags.
