Description

Technical Field

[0001] This utility model relates to the field of pet supplies, specifically a hollowed-out aluminum climbing ladder. Background Technology

[0002] As people's living standards continue to improve, pet ownership is gradually becoming a common lifestyle, and pets are gaining increasing importance in the family. The pet supplies market is also expanding rapidly. Consumers' demands for pet supplies are no longer limited to basic items like food bowls and beds, but are paying more attention to their pets' quality of life and activity space. The demand for highly functional and ingeniously designed pet activity devices is becoming increasingly strong, providing ample room for innovation and development in related products.

[0003] Most pet activity devices currently on the market have relatively simple structures and limited forms. Most products are fixed in shape, lacking flexibility and adjustability, making it difficult to meet the diverse activity needs of pets and different family layouts. Furthermore, their design often focuses on meeting basic pet activity needs, neglecting portability and ease of storage, thus failing to adapt well to the compact living environments of modern families.

[0004] Traditional pet activity enclosures are typically designed by first determining the general framework, then using sturdy materials to build the main frame, such as ordinary steel for the support structure, and finally laying a flat surface on the frame to serve as the pet's activity area. The installation process is also fairly conventional, assembling the components together through simple welding or bolting. The overall design philosophy prioritizes structural stability while neglecting lightweight design and ease of operation.

[0005] However, existing pet activity devices have significant drawbacks. Due to the use of heavy materials, they are bulky and extremely inconvenient to move and transport; the fixed structure cannot be folded for storage, taking up considerable space and hindering home tidying; furthermore, the extended sections lack effective support and limiting designs, resulting in poor stability, difficulty in expanding the pet's activity range, and an inability to satisfy the pet's active nature. There is considerable room for improvement in both user experience and safety. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a hollowed-out aluminum ladder with steps to solve the technical problem.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hollowed-out aluminum ladder with steps, including a bottom mounting frame, a pair of bottom support frames symmetrically arranged on one side of the bottom mounting frame, a pair of first middle section support frames symmetrically arranged on the other side of the bottom mounting frame away from the bottom support frames, a first mounting and fixing frame rotatably arranged between the pair of first middle section support frames, and a hollowed-out metal plate arranged inside the first mounting and fixing frame.

[0008] By adopting the above technical solution, the installation of the fixed frame and the perforated metal plate can be achieved.

[0009] The present invention is further configured such that a pair of second middle section support frames are connected to the side of the first mounting and fixing frame away from the bottom support frame, a second mounting and fixing frame is rotatably arranged between the pair of second middle section support frames, the top end of the first middle section support frame is movably connected to the end of the second mounting and fixing frame near the bottom mounting frame, and a second connecting shaft is provided outside the first middle section support frame in cooperation with the second mounting and fixing frame.

[0010] By adopting the above technical solution, rotation between the mounting frame and the support frame is achieved, allowing the device to be rotated and folded.

[0011] The present invention is further configured such that a third connecting shaft is provided on the outside of the first middle section support frame and the first mounting and fixing frame between the first middle section support frames is rotatably fixed by the third connecting shaft, and a first connecting shaft is provided on the outside of a pair of second middle section support frames and the second mounting and fixing frame between the first connecting shafts is rotatably fixed by the first connecting shaft.

[0012] By adopting the above technical solution, the fixed frame is rotated and fixed by the connecting shaft, so that the device can be folded and stored.

[0013] The present invention is further configured such that a first limiting rod is rotatably connected to the first connecting shaft, a second limiting rod is rotatably connected to the third connecting shaft, and the other end of the first limiting rod and the other end of the second limiting rod are rotatably connected to the second connecting shaft.

[0014] By adopting the above technical solution, the maximum angle of device deployment is limited through the cooperation of the first and second limiting rods.

[0015] The present invention is further configured such that a pair of fixing strips are symmetrically fixed at one end of the second mounting frame away from the first mounting frame.

[0016] By adopting the above technical solution, the device can be guided to unfold while the extension end is fixed.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model uses a perforated metal plate, aluminum first and second mounting frames, and a steel bottom mounting bracket. This reduces the overall weight, making it easier to move; it also reduces the weight of the extension end, ensuring structural stability after unfolding.

[0019] 2. This utility model facilitates the pulling of the unfolding device by setting a fixed strip, and can also help support the extension end; through the cooperation of the first and second limiting rods and the connecting shaft, the device is limited to unfolding to a fixed 90° shape, ensuring stable use and improving the user experience.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Hollowed-out aluminum staircase with steps, such as Figure 1-2As shown, the device includes a bottom mounting bracket 1. A pair of bottom support brackets 5 are symmetrically arranged on one side of the bottom mounting bracket 1. A pair of first middle section support brackets 6 are symmetrically arranged on the other side of the bottom mounting bracket 1 away from the bottom support brackets 5. A first mounting frame 2 is rotatably connected between the pair of first middle section support brackets 6. A pair of second middle section support brackets 12 are connected to the side of the first mounting frame 2 away from the bottom support brackets 5. A second mounting frame 13 is rotatably connected between the pair of second middle section support brackets 12. The top end of the first middle section support bracket 6 is movably connected to the end of the second mounting frame 13 near the bottom mounting bracket 1. A second connecting shaft 9 is provided on the outside of the first middle section support bracket 6 in conjunction with the second mounting frame 13. A third connecting shaft 11 is provided on the outside of the first middle section support bracket 6 in conjunction with the first mounting frame 2. The first mounting and fixing frame 2 between the first middle section support frame 6 is rotatably fixed by the third connecting shaft 11. A pair of second middle section support frames 12 are externally fitted with second mounting and fixing frames 13, each with a first connecting shaft 7. The second mounting and fixing frames 13 between the first connecting shafts 7 are rotatably fixed by the first connecting shafts 7. Through the cooperation between the first middle section support frame 6, the second middle section support frame 12, the first mounting and fixing frame 2, and the second mounting and fixing frame 13, the first mounting and fixing frame 2 and the second mounting and fixing frame 13 can be folded and stored. Correspondingly, a perforated metal plate 3 is provided inside the first mounting and fixing frame 2 and the second mounting and fixing frame 13. In actual use, by installing an additional fixing frame at the top of the second mounting and fixing frame 13, the extended distance of the structure can be increased, thus increasing the pet's activity range.

[0026] Based on the above structure, this application reduces the overall weight of the structure by setting a hollow metal plate 3. On the one hand, this facilitates the movement of the device, and on the other hand, it reduces the weight at the extended end after unfolding, ensuring the stability of the structure. In conjunction with this, the first mounting frame 2 and the second mounting frame 13 can be made of aluminum to further reduce the overall weight of the structure and ensure lightweighting. The bottom mounting frame 1 can be made of steel to ensure the bottom center of gravity and enhance the overall stability of the structure.

[0027] Furthermore, a pair of fixing strips 4 are symmetrically fixed at the end of the second mounting frame 13 away from the first mounting frame 2. The fixing strips 4 act as handles, allowing the user to guide the device to unfold by pulling the fixing strips 4. At the same time, by connecting the fixing strips to the wall or support points, the extension end of the device is supported, further ensuring the stability of the device.

[0028] A first limiting rod 8 is rotatably connected to the first connecting shaft 7, and a second limiting rod 10 is rotatably connected to the third connecting shaft 11. The other end of the first limiting rod 8 and the other end of the second limiting rod 10 are rotatably connected to the second connecting shaft 9. With this arrangement, when the device is unfolded to 90°, the first limiting rod 8 and the second limiting rod 10 cannot continue to move under the action of the first middle section support frame 6 and the second middle section support frame 12, thereby limiting the unfolding degree of the entire device and allowing the device to be used in a fixed form, thus ensuring the user experience of the device.
