Description
Technical Field
[0001] This utility model relates to the field of decoration engineering technology, and in particular to a double-sided aluminum alloy staircase with good stability. Background Technology
[0002] In daily life, whether in home life, industrial production, or construction, working at heights is frequently required. Double-sided aluminum alloy ladders, as an important tool for accessing heights, are widely used in various scenarios due to their advantages such as light weight, high strength, and corrosion resistance. For example, in home renovations, ladders are needed to install light fixtures and paint walls; in warehouses, workers often use ladders to store and retrieve goods at higher locations; and on construction sites, workers also utilize ladders for working at heights.
[0003] The double-sided aluminum alloy staircase mainly consists of an aluminum alloy frame, treads, handrails, and connectors. The aluminum alloy frame is the main supporting structure of the staircase. When a user steps onto a tread, the tread bears the weight and transfers it to the aluminum alloy frame. The frame, through its robust structure and rational design, evenly distributes the weight to each support point, ensuring the stability of the staircase. Meanwhile, the handrails provide additional support and balance for users going up and down the staircase. Users can adjust the position and angle of the staircase according to their needs to adapt to different scenarios.
[0004] In existing technologies, a simple and stable structure is formed by just two ladder frames, but there are still safety hazards caused by instability when users use it. Moreover, there are risks in the simple folding support of traditional equipment. Therefore, a double-sided aluminum alloy step ladder with good stability is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a double-sided aluminum alloy staircase with good stability, aiming to improve the stability of the equipment and the safety of the folding support in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-sided aluminum alloy staircase with good stability, including a ladder frame, a reinforcing mechanism fixedly connected to the bottom of the ladder frame, an anti-slip sleeve fixedly connected to the bottom of the ladder frame, a folding mechanism fixedly installed on the outer side of the ladder frame, and multiple treads installed on the inner side of the ladder frame, with anti-slip components provided on the top of the treads.

[0009] As a further description of the above technical solution: a connecting column 2 is rotatably connected to the outer side of the middle shaft of the fixed column 2, a rotating bar is rotatably connected to the outer side of the lower outer shaft of the ladder frame, an anti-slip sleeve is provided on the outer side of the bottom of the rotating bar, and an anti-slip sleeve is provided on the outer side of the bottom of the ladder frame.

[0022] 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.
[0023] Reference Figures 1 to 3 This utility model provides an embodiment of a stable double-sided aluminum alloy staircase, including a ladder frame 1. The ladder frame 1 provides an installation base for the steps 20, reinforcement mechanisms, folding mechanisms, etc., ensuring the structural stability of the entire staircase. The bottom of the ladder frame 1 is fixedly connected to a reinforcement mechanism, and the bottom of the ladder frame 1 is fixedly connected to an anti-slip sleeve 14. The anti-slip sleeve 14 is made of anti-slip rubber, has good elasticity and wear resistance, and has good anti-slip performance. It can provide sufficient friction under different ground conditions to ensure the stability and safety of the staircase. The anti-slip sleeve 14 is set at the bottom of the ladder frame 1 and on the outer side of the bottom of the rotating bar 13, which can effectively improve the stability of the staircase and prevent the staircase from sliding during use. The outer side of the ladder frame 1 is fixedly installed with a folding mechanism, and the inner side of the ladder frame 1 is installed with multiple steps 20. The steps 20 provide a platform for users to step on, making it convenient for users to climb. The top of the steps 20 is provided with an anti-slip component, which can effectively improve the safety of users.
[0024] The reinforcement mechanism includes a fixed column 2, which transmits the movement of the ladder frame 1 to a sliding column 3 for initial cushioning. The sliding column 3 is fixedly connected to the inner side of the fixed column 2, and a spring 4 is slidably connected to the outer side of the sliding column 3. The sliding column 3 and spring 4 cooperate to slide inside the fixed column 2. When the ladder sways, the sliding column 3 can compress or stretch the spring 4 by sliding up and down, thus providing initial cushioning. When the ladder sways, the spring 4 can absorb and release energy through compression and stretching, thus providing cushioning, reducing the swaying amplitude of the ladder, and improving stability. A connecting column 5 is fixedly connected to the bottom of the sliding column 3, and a connecting block 6 is fixedly installed at the bottom of the connecting column 5. The connecting column 5 connects the sliding column 3 and the connecting block 6, transmitting the movement of the sliding column 3 to the connecting block 6. A fixed column 12 passes through the interior of the connecting block 6, allowing the connecting column 10 to rotate around the fixed column 12. Simultaneously, the connecting column 10 moves at one end during its up and down movement, thus achieving further cushioning of the reinforcement mechanism. A fixed column 3 12 is connected through the inner side of the connecting block 6. The fixed column 3 12 provides the axis for the installation and rotation of the connecting column 2 10 and the connecting plate 1 7, allowing the connecting column 2 10 to rotate outside the fixed column 3 12. Two connecting columns 2 10 are rotatably connected to the outer side of the fixed column 3 12. The connecting columns 2 10 transmit the up and down movement of the connecting block 6 to the buffer assembly. The connecting plate 1 7 is rotatably connected to the outer side of the fixed column 3 12. The connecting plate 1 7 cooperates with the limiting block 1 8 to limit the movement range of the connecting column 2 10, ensuring that the connecting column 2 10 can rotate within a fixed range, thereby realizing the buffering effect of the reinforcement mechanism. The outer side of the connecting plate 1 7 is provided with a limiting block 1 8, which limits the movement range of the connecting column 2 10. The outer side of the shaft inside the limiting block 1 8 is rotatably connected to the buffer assembly. The bottom of the buffer assembly is fixedly connected to a limiting block 2 9, which ensures that the buffer assembly can move within a fixed range.
[0025] The buffer assembly includes a second fixed post 11. The upper inner side of the second fixed post 11 is rotatably connected to the outer side of the outer shaft of the first limiting block 8. A spring is fixedly connected to the middle of the second fixed post 11 for further buffering. The bottom of the second fixed post 11 is fixedly connected to the top of the second limiting block 9. After multiple buffering cycles, the buffer stabilizes at the second limiting block 9. A second connecting post 10 is rotatably connected to the outer side of the middle shaft of the second fixed post 11. A rotating strip 13 is rotatably connected to the outer side of the lower outer shaft of the ladder frame 1. The rotating strip 13 reinforces the support area of the ladder frame 1. An anti-slip sleeve 14 is provided on the outer bottom of the rotating strip 13, and an anti-slip sleeve 14 is also provided on the outer bottom of the ladder frame 1.
[0026] Reference Figure 1 , Figure 2 , Figure 4The folding mechanism includes a second connecting plate 18, which is an important component connecting the ladder frame 1 and the rotating assembly, providing installation and support for the rotating assembly. The outer side of the second connecting plate 18 is fixedly connected to the outer side of the ladder frame 1. The rotating assembly is rotatably connected to the inner side of the upper ring of the second connecting plate 18. The outer side of the rotating assembly is fixedly connected to one side of the ladder frame 1, i.e., the side away from the second connecting plate 18. The outer side of the ladder frame 1 is fixedly connected to a support assembly.
[0027] The rotating assembly includes a second rotating shaft 17, the outer side of which is rotatably connected to the inner side of the upper ring of a second connecting plate 18. A third connecting plate 19 is rotatably connected to the outer side of the rotating shaft 17, away from the connecting plate 18. The third connecting plate 19 connects the rotating shaft 17 and the ladder frame 1, transmitting the rotation of the rotating shaft 17 to the ladder frame 1. The rotating shaft 17 is the core component of the rotating assembly. The connecting plates 18 and 19 allow the ladder frame 1 to rotate around the rotating shaft 17, enabling the folding and unfolding of the ladder. The outer side of the third connecting plate 19 is fixedly connected to the outer side of the ladder frame 1. The support assembly includes a rotating plate 15, made of sturdy aluminum alloy. One end of the rotating plate 15 is rotatably connected to an outer shaft of the ladder frame 1, allowing the rotating plate 15 to automatically unfold when the ladder is unfolded, providing support for the ladder frame 1. When the ladder is folded, the rotating plate 15 can automatically fold up with the movement of the ladder frame 1, without occupying additional space. One end of the rotating plate 15 is rotatably connected to the outside of the outer shaft of the ladder frame 1. One end of the rotating plates 15 on both the left and right sides, i.e., the end furthest from the ladder frame 1, is rotatably connected to a rotating shaft 16. The rotating shaft 16 connects the left and right rotating plates 15, allowing the rotating plates 15 on both sides to move synchronously, thus improving the stability of the support assembly. The anti-slip assembly includes an anti-slip strip 21. The bottom of the anti-slip strip 21 is fixedly connected to the top of the pedal 20. The anti-slip strip 21 increases the friction of the pedal 20, preventing the user from slipping during climbing and improving safety.
[0028] Working principle: When using this equipment, the user holds onto the ladder frame 1 and steps on the pedal 20 to walk upwards, which shakes the fixed column 1 2. When the fixed column 1 2 shakes, under the elastic force of the sliding column 3, it drives the spring 1 4 and the connecting column 1 5 to move up and down inside the fixed column 1 2, thereby driving the connecting block 6 to move up and down. When the connecting block 6 moves up and down, it passes through the fixed column 3 12 inside, causing one end of the connecting column 2 10 to move up and down. The other end rotates around the axis on the upper part of the fixed column 2 11 under the restriction of the connecting plate 1 7 and the limiting block 1 8. At the same time, the spring installed in the middle of the fixed column 2 11 provides buffering to reduce vibration. After multiple buffering, the bottom is stabilized by the limiting block 2 9. At the same time, the stability of the equipment is increased by the rotating bar 13.
[0029] When the equipment is not in use, connecting plate 2 18 and connecting plate 3 19 rotate around rotating shaft 2 17, allowing the ladders 1 on both sides to be folded up. At the same time, they rotate in conjunction with rotating plate 15 and rotating shaft 16. When the equipment is in use, the ladders 1 on both sides are pushed open and rotated around rotating shaft 2 17 by connecting plate 2 18 and connecting plate 3 19, while being supported and fixed by rotating plate 15 and rotating shaft 16, thereby achieving the function of folding and unfolding.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
