Description

Technical Field

[0001] This utility model relates to the field of folding climbing ladder technology, and in particular to a folding climbing ladder structure. Background Technology

[0002] Climbing ladders play an indispensable role as a commonly used auxiliary tool in daily life, outdoor activities, and various maintenance work. However, existing climbing ladder products have many shortcomings. Traditional fixed climbing ladders have a fixed and unchangeable structure, are bulky and heavy, and are not only difficult to place in environments with limited space, such as small warehouses or car interiors, but also occupy a lot of valuable space, causing great inconvenience for use and storage.

[0003] While some existing folding climbing ladders solve the storage problem to some extent, they have significant design flaws. The folding and unfolding process of some folding climbing ladders is cumbersome, requiring multiple steps and complex operations. This not only wastes time and effort but also increases the difficulty of use, making them extremely unfriendly to users who urgently need to use them or are unfamiliar with their operation. Furthermore, some folding climbing ladders have poor structural stability after folding, and are prone to falling apart due to shaking or collisions during transport or storage, posing safety hazards. Therefore, they fail to adequately meet people's needs for convenient, stable, and practical climbing tools.

[0004] Therefore, this application proposes a folding ladder structure, providing a new technical solution to address the aforementioned technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide a folding ladder structure to address the above-mentioned technical problems. Through the structural design of the folding ladder component, a damping pivot is used to achieve smooth rotation between ladder sections, making folding and unfolding operations easy and convenient. After folding, the first ladder section can be stored inside the second ladder section. Combined with the storage cavity design of a car roof rack, the space occupied is greatly reduced, making it easy to carry and store. The overall stability is strong, effectively improving the convenience and practicality of use.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] Example 1:

[0030] Please refer to Figures 1-3 A folding climbing ladder structure, comprising:

[0031] The folding climbing ladder assembly 1 includes a first ladder section 2, a second ladder section 3, and a slide 4. The second ladder section 3 is located at one end of the first ladder section 2, and the slide 4 is located at the other end of the first ladder section 2. A first adjustment mechanism is provided between the second ladder section 3 and the first ladder section 2 to adjust their relative position. A second adjustment mechanism is provided between the slide 4 and the first ladder section 2, also for adjusting their relative position.

[0032] Multiple footplates 7 are fixedly connected to both the first section 2 and the second section 3. The footplates 7 are evenly distributed to provide users with footholds and support points when climbing. The connection between the first section 2 and the second section 3 is located below the uppermost footplate 7 of the second section 3. This design ensures that when the ladder is unfolded, the uppermost footplate 7 of the second section 3 limits the unfolded first section 2 and the second section 3, thereby effectively ensuring the stability of the structure when unfolded.

[0033] Furthermore, the first adjustment mechanism includes a first damping shaft 5. The first ladder section 2 and the second ladder section 3 are rotatably connected through the first damping shaft 5. The first damping shaft 5 can provide a certain resistance during rotation, so that the ladder can be operated smoothly when unfolding or folding, avoiding safety hazards or damage caused by excessive rotation.

[0034] Furthermore, the second adjustment mechanism includes a second damping shaft 6. The first ladder section 2 and the slide 4 are rotatably connected through the second damping shaft 6. Similarly, by utilizing the characteristics of the second damping shaft 6, a stable and controllable rotational relationship is achieved between the slide 4 and the first ladder section 2.

[0035] Furthermore, the width of the inner side of the second ladder section 3 is greater than the width of the first ladder section 2, allowing the first ladder section 2 to be folded inside the second ladder section 3. This size design enables the first ladder section 2 to be folded inside the second ladder section 3. When the ladder is not in use, the first ladder section 2 can be folded into the second ladder section 3, effectively reducing the overall space occupied by the ladder and making it easier to store and carry.

[0036] Through the above structural design, this folding climbing ladder achieves flexible adjustment and convenient folding. Users can adjust the unfolding degree of the ladder according to actual needs through the adjustment mechanism to adapt to climbing tasks of different heights. At the same time, the foldable design greatly improves the portability of the ladder, making it convenient for transportation and storage in different scenarios.

[0037] Example 2:

[0038] The folding ladder structure provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4As shown, it also includes a car roof rack 8, with a storage cavity 9 on the inner side of the car roof rack 8. The folding ladder assembly 1 can be placed inside the storage cavity 9 when folded, achieving integrated storage with the car roof rack 8. This makes full use of the space of the car roof rack 8 and properly stores the folded folding ladder assembly 1, preventing it from swinging around during driving and causing safety hazards to the vehicle and people. The slide 4 is slidably connected to the inner wall of the storage cavity 9, making it smoother to put into or take out the folding ladder assembly 1. The first ladder section 2 and the second ladder section 3 can slide out through the end of the storage cavity 9. When the folding ladder assembly 1 is needed, the user only needs to slide it out from the end of the storage cavity 9 and then unfold it for climbing. After use, the folding ladder assembly 1 is folded and slid back into the storage cavity 9.

[0039] Furthermore, the outer sides of both the slide 4 and the second ladder 3 are fixedly connected with cushioning strips 10 for shock absorption and to prevent metal scratches.

[0040] The above structural design enhances ease of use and storage efficiency. Combined with the car roof rack 8, the climbing ladder can be carried in the vehicle, readily meeting users' climbing needs in outdoor or maintenance scenarios, truly achieving a perfect blend of practicality and portability.
