Description

Technical Field

[0001] This utility model relates to the field of folding ladder technology, and more specifically, to a multi-functional aluminum alloy folding ladder. Background Technology

[0002] As we all know, most stores, factory warehouses and homes need to be equipped with movable fixed ladders to facilitate the movement of goods from or to higher places. However, fixed ladders are gradually being replaced by folding ladders, especially in supermarkets and stores, due to their large size, the large space they occupy when not in use, and the inconvenience of storage.

[0003] Currently, folding ladders can only be used as ladders, and their functionality is limited. If they are to be used for other purposes, corresponding devices need to be purchased, such as clothes racks for drying clothes. When not in use, folding ladders can only be placed for storage, which is a waste of resources. After unfolding, the angle of the two ladder frames cannot be fixed, which causes the ladder frames to shrink during use, reducing stability and posing a high safety hazard.

[0004] Utility Model Content (1) Technical Problem to be Solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-functional aluminum alloy folding ladder, which has the characteristics of multiple functions, such as drying clothes, and high stability.

[0005] (2) Technical solution To achieve the above objectives, this utility model provides a multi-functional aluminum alloy folding ladder, comprising a first ladder frame, with first connecting members fixedly connected to both sides of the top of the first ladder frame, and second connecting members movably connected to opposite sides of the two first connecting members via movable shafts. The bottom of the two second connecting members is fixedly connected to the same second ladder frame. Movable rods are movably connected to opposite sides of the first and second ladder frames, and the opposite ends of the two movable rods are movably connected via hinges. The same sleeve is movably fitted onto the two movable rods. The structures of the first and second ladder frames are identical. Support bars are movably connected to both sides of the first ladder frame via movable shafts, and through holes are provided on both support bars. A movable frame is movably connected inside the first ladder frame via movable shafts, and multiple step rods are fixedly connected inside the movable frame. Studs are threaded through both sides of the inner wall of the movable frame, and one end of each stud overlaps with one side of the inner wall of the first ladder frame.

[0006] When using the aluminum alloy multi-functional folding ladder of this technical solution, the movable frame, support bars, through holes and studs work together to allow the movable frame to be unfolded and used as a clothes rack when the folding ladder is not in use, thus improving the functionality of the folding ladder. The movable rod and sleeve can fix the angle of the first and second ladder frames after unfolding, thus improving the stability of the folding ladder.

[0007] Furthermore, both the bottom sides of the first and second ladders are fixedly connected with legs.

[0008] Furthermore, a fixing bolt is threaded through the top side of the sleeve, and one end of the fixing bolt overlaps with the top of a movable rod.

[0009] Furthermore, both sides of the first ladder frame are fixedly connected with locking blocks, and the two support bars are respectively locked into the two locking blocks.

[0010] Furthermore, the card block has an overall L-shaped design.

[0011] (3) Beneficial effects In summary, this utility model has the following beneficial effects: 1. Through the combined action of the movable frame, support bars, through holes and studs, the movable frame can be unfolded and used as a clothes rack when the folding ladder is not in use, which improves the functionality of the folding ladder. The movable rod and sleeve can fix the angle of the first and second ladder frames after unfolding, which improves the stability of the folding ladder. 2. By setting support legs, the contact area between the first and second ladder frames and the ground is increased, further improving the stability of the folding ladder. By setting fixing bolts, the position of the sleeve can be easily fixed. By setting locking blocks, the support bars can be limited. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0016] Example: The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a multi-functional aluminum alloy folding ladder, including a first ladder frame 1. First connecting members 2 are fixedly connected to both sides of the top of the first ladder frame 1. Second connecting members 3 are movably connected to opposite sides of the two first connecting members 2 via movable shafts. A second ladder frame 4 is fixedly connected to the bottom of the two second connecting members 3. Movable rods 6 are movably connected to opposite sides of the first ladder frame 1 and the second ladder frame 4. The opposite ends of the two movable rods 6 are movably connected via hinges. A sleeve 7 is movably sleeved on the two movable rods 6. Through the arrangement of the movable rods 6 and the sleeve 7, the angle of the first ladder frame 1 and the second ladder frame 4 after unfolding can be fixed, thus improving efficiency. To ensure the stability of the folding ladder, the structures of the first ladder frame 1 and the second ladder frame 4 are identical. Both sides of the first ladder frame 1 are movably connected to support bars 9 via movable shafts, and both support bars 9 have through holes 10. Inside the first ladder frame 1, a movable frame 12 is movably connected via movable shafts. Multiple steps 13 are fixedly connected inside the movable frame 12. Both sides of the inner wall of the movable frame 12 are threaded with studs 14, and one end of each stud 14 overlaps with the inner wall of the first ladder frame 1. Through the combined action of the movable frame 12, support bars 9, through holes 10, and studs 14, the movable frame 12 can be unfolded and used as a clothes rack when the folding ladder is not in use, thus improving the functionality of the folding ladder.

[0018] Specifically, the bottom sides of the first ladder 1 and the second ladder 4 are fixedly connected with support legs 5. The top side of the sleeve 7 is threaded with a fixing bolt 8. One end of the fixing bolt 8 overlaps with the top of a movable rod 6. The two sides of the first ladder 1 are fixedly connected with locking blocks 11. Two support bars 9 are respectively locked in the two locking blocks 11. The locking blocks 11 are L-shaped in overall design.

[0019] By adopting the above technical solution, the contact area between the first ladder frame 1 and the second ladder frame 4 and the ground is increased by setting the support legs 5, which further improves the stability of the folding ladder. The position of the sleeve 7 is easily fixed by setting the fixing bolts 8, and the support bar 9 can be limited by setting the locking block 11.

[0020] The working principle of this utility model is as follows: When in use, unfold the first ladder frame 1 and the second ladder frame 4. The two movable rods 6 fall to a horizontal position. Slide the sleeve 7 to move the sleeve 7 to the connection position of the two movable rods 6. Rotate the fixing bolt 8. One end of the fixing bolt 8 abuts against the top of one of the movable rods 6 to fix the position of the sleeve 7. Then the user can use it by climbing the step bar 13. When not in use, rotate the stud 14 so that one end of the stud 14 is no longer connected to the first ladder frame 1. Unfold the movable frame 12 outward. Pull the support bar 9 to separate the support bar 9 from the locking block 11. Rotate the support bar 9 to insert one end of the stud 14 into the through hole 10 so that the support bar 9 supports the movable frame 12. Repeat the above operation to unfold the movable frame 12 in the second ladder frame 4. Then clothes can be hung on the step bar 13 to be used as a clothes rack.
