Description

Technical Field

[0001] This utility model relates to the field of stacked ladder technology, and in particular to a steel structure stacked ladder that is easy to assemble. Background Technology

[0002] A steel structure stacked ladder is a foldable or detachable ladder made of high-strength steel. As a common climbing tool, steel structure stacked ladders are widely used due to their sturdy structure, durability, and strong load-bearing capacity.

[0003] Traditional steel stacked ladders are cumbersome to assemble, which can lead to long installation times and significantly reduce their efficiency and ease of use. Therefore, those skilled in the art have provided a steel stacked ladder that is easy to assemble to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a steel structure stacking ladder that is easy to assemble. Through the connecting device, it can connect the large frame and the small frame to complete the assembly of the entire stacking ladder, and it can greatly simplify the installation process and improve the convenience of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure stacked ladder that is easy to assemble, comprising a stacked ladder body and multiple first frames, the multiple first frames being arranged in a stepped manner at the center of the outer side of the stacked ladder body, a large frame being fixedly connected to the center of the rear inner wall of each of the multiple first frames, a second frame being provided at the rear center of the upper end face of each of the multiple first frames, a small frame being fixedly connected to the center of the rear inner wall of each of the multiple second frames, and a connecting device being provided at the center of the interior of each of the multiple small frames;

[0006] The connecting device includes three first angle irons, which are arranged horizontally at the center of the front inner wall of the large frame. The center of the upper end face of the three first angle irons is provided with three first mounting holes arranged in a front-to-back manner. The center of the interior of the small frame is provided with three second angle irons, which are arranged horizontally at the center of the upper end face of the three second angle irons. The center of the upper end face of the three second angle irons is provided with three second mounting holes arranged in a front-to-back manner.

[0007] The above technical solution involves placing a large frame on top of a small frame, ensuring the corresponding arrangement of the first and second angle irons and the first and second mounting holes. The connection between the first and second angle irons allows the large and small frames to be connected, completing the assembly of the entire stacked ladder. This significantly simplifies the installation process and improves ease of use.

[0008] Furthermore, the three first angle irons at the lower end of the large frame near the top are respectively provided with the three second angle irons at the upper end of the small frame near the bottom, and the three first mounting holes are respectively provided with the three second mounting holes, and are fixedly connected by bolts.

[0009] The above technical solution, by correspondingly setting the first angle iron and the second angle iron, and by correspondingly setting the first mounting hole and the second mounting hole, meets the installation requirements. The first mounting hole and the second mounting hole are then fixedly connected by bolts, which satisfies the installation between the large frame and the small frame.

[0010] Furthermore, each of the large frames has a support rod located at the upper center of its interior, and both ends of the support rods are fixedly connected to the two inner sidewalls of the large frames, respectively.

[0011] The above technical solution, by fixing the support rod to the inner wall of the large frame, enhances the rigidity of the entire structure and makes the main body of the stacked ladder more stable when bearing load, reducing the possibility of shaking and deformation, thereby improving the reliability and stability of the main body of the stacked ladder during use.

[0012] Furthermore, step plates are fitted at the center of the outer side of each of the large frames;

[0013] The above technical solution provides a safe and stable surface through the step plate, ensuring the safety of users in various environments.

[0014] Furthermore, each of the inner sidewalls of the second frame is provided with a connecting rod at the rear end of its center. One end of each connecting rod is fixedly connected to the inner sidewalls of the second frame and the sidewalls of the small frame, and the other end is fixedly connected to the inner sidewalls of the first frame and the sidewalls of the large frame.

[0015] The above technical solution connects and supports the first frame, second frame, large frame, and small frame via connecting rods, which significantly enhances the stability of the entire structure and thus improves the load-bearing capacity of the stacked ladder.

[0016] Furthermore, the multiple first frames and multiple second frames are each n-shaped, and are respectively fixedly connected to multiple large frames and multiple small frames;

[0017] The above technical solution, by designing the first and second frames as n-sided shapes and connecting them with the large and small frames through a nesting connection, increases the support points of the stacked ladder body and improves its stability.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, when using the easily assembled steel structure stacked ladder, the large frame is placed on top of the small frame, so that the first angle iron and the second angle iron are correspondingly set, and the first mounting hole and the second mounting hole are correspondingly set. Then, the first angle iron and the second angle iron are fixedly connected by bolts, so that the large frame and the small frame are connected together, completing the assembly of the entire stacked ladder. This greatly simplifies the installation process and improves the convenience of use.

[0020] 2. In this utility model, the support rod is fixedly connected to the inner wall of the large frame, which enhances the rigidity of the entire structure. The connecting rod connects and supports the first frame, the second frame, the large frame, and the small frame, which significantly enhances the stability of the entire structure. This makes the main body of the stacked ladder more stable when bearing load, reducing the possibility of shaking and deformation, thereby improving the reliability and stability of the main body of the stacked ladder during use.

[0027] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-4 This utility model provides an embodiment of a steel structure stacked ladder that is easy to assemble, comprising a main body 1 and multiple first frames 2. The multiple first frames 2 are arranged in a stepped manner at the center of the outer side of the main body 1. A large frame 3 is fixedly connected to the center of the rear inner wall of each of the multiple first frames 2. A second frame 5 is provided at the rear center of the upper surface of each of the multiple first frames 2. A small frame 6 is fixedly connected to the center of the rear inner wall of each of the multiple second frames 5. A connecting device 7 is provided at the center of the interior of each of the multiple small frames 6. The connecting device 7 enables the connection of the large frame 3 and the small frame 6 to complete the assembly of the entire stacked ladder, greatly simplifying the installation process and improving the convenience of use.

[0029] Support rods 4 are provided at the upper center of the interior of multiple large frame bodies 3. The two ends of the multiple support rods 4 are fixedly connected to the two inner side walls of the multiple large frame bodies 3 respectively. By fixing the support rods 4 to the inner side walls of the large frame bodies 3, the rigidity of the entire structure is enhanced, and the main body of the stacked ladder 1 is more stable when bearing load, reducing the possibility of shaking and deformation, thereby improving the reliability and stability of the main body of the stacked ladder 1 during use.

[0030] Multiple large frame 3 are fitted with step plates 8 at the center of their outer sides, providing a safe and stable surface and ensuring user safety in various environments. Multiple second frame 5 are equipped with connecting rods 9 at the rear end of the center of their two inner side walls. One end of each connecting rod 9 is fixedly connected to the inner side wall of the multiple second frame 5 and the side wall of the multiple small frame 6, and the other end is fixedly connected to the inner side wall of the multiple first frame 2 and the side wall of the multiple large frame 3. The connecting rods 9 connect and support the first frame 2, second frame 5, large frame 3 and small frame 6, which significantly enhances the stability of the entire structure and improves the load-bearing capacity of the stacked ladder.

[0031] The multiple first frames 2 and multiple second frames 5 are each n-shaped, and are respectively nested and fixedly connected to multiple large frames 3 and multiple small frames 6. By designing the shapes of the first frames 2 and the second frames 5 as n-sided and using nested connections between them and the large frames 3 and the small frames 6, the support points of the stacked ladder body 1 are increased, thus improving its stability.

[0032] like Figure 2 , 3As shown in Figure 4, the connecting device 7 includes three first angle irons 701. The three first angle irons 701 are arranged horizontally at the center of the front inner wall of the large frame 3. The center of the upper end face of the three first angle irons 701 is provided with three first mounting holes 702 arranged front to back. The center of the interior of the small frame 6 is provided with three second angle irons 703 arranged horizontally. The center of the upper end face of the three second angle irons 703 is provided with three second mounting holes 704 arranged front to back. The large frame 3 is placed on the upper end of the small frame 6, so that the first angle irons 701 and the second angle irons 703 are correspondingly set, and the first mounting holes 702 and the second mounting holes 704 are correspondingly set. The connection between the first angle irons 701 and the second angle irons 703 allows the large frame 3 and the small frame 6 to be connected, completing the assembly of the entire stacked ladder. This greatly simplifies the installation process and improves the convenience of use.

[0033] The three first angle irons 701 at the lower end of the upper large frame 3 and the three second angle irons 703 at the upper end of the lower small frame 6 are respectively set. The three first mounting holes 702 are respectively set with the three second mounting holes 704, and are fixedly connected by bolts. The corresponding arrangement of the first angle irons 701 and the second angle irons 703, and the corresponding arrangement of the first mounting holes 702 and the second mounting holes 704, meets the installation requirements. The fixed connection of the first mounting holes 702 and the second mounting holes 704 by bolts meets the installation requirements between the large frame 3 and the small frame 6.

[0034] Working principle: When using the easily assembled steel structure stacked ladder, the large frame 3 is placed on top of the small frame 6, which satisfies the corresponding setting between the first angle iron 701 and the second angle iron 703, and the corresponding setting between the first mounting hole 702 and the second mounting hole 704. Then, the connection between the first angle iron 701 and the second angle iron 703 is used to connect the large frame 3 and the small frame 6, completing the assembly of the entire stacked ladder. This greatly simplifies the installation process and improves the convenience of use.

[0035] By fixing the support rod 4 to the inner wall of the large frame 3, the rigidity of the entire structure is enhanced, making the main body 1 of the stacked ladder more stable when bearing load, reducing the possibility of swaying and deformation, thereby improving the reliability and stability of the main body 1 of the stacked ladder during use. Furthermore, the first frame 2, the second frame 5, the large frame 3 and the small frame 6 are connected and supported by the connecting rod 9, which significantly enhances the stability of the entire structure, thereby improving the load-bearing capacity of the stacked ladder.

[0036] The step plate 8 provides a safe and stable surface, ensuring the safety of users in various environments and enabling it to meet the assembly and use of the main body 1 of the stacked ladder.
