[0031] 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.

[0032] Please see Figure 1-8 This utility model provides a technical solution: a detachable folding ladder, including two sets of support legs 1, each set having two support legs 1 arranged in a figure-eight shape, the support legs 1 being connected by movable parts, the support legs 1 being connected by connecting components, and the connecting components at the top of the support legs 1 being connected by auxiliary parts.

[0033] See Figure 1 The interior of each of the supporting legs 1 is hollow.

[0034] See Figure 5 The auxiliary component includes a hook-shaped plate 22 and a movable rod 23 with a circular notch. The movable rod 23 is slidably disposed in a movable groove formed inside the hook-shaped plate 22. The movable rod 23 can rotate in the hook-shaped plate 22. The auxiliary component is designed to allow the connecting assembly at the top of its support leg 1 to be movably connected.

[0035] See Figure 1 The movable component includes an arc-shaped piece 4 movably installed on the inner side of the support leg 1. The tops of the arc-shaped pieces 4 are connected by bolts and nuts. The arc-shaped pieces 4 are hinged to the inner side of the support leg 1. The bolts and nuts also allow the two arc-shaped pieces 4 to be manually opened, so that the folding ladder is supported in a figure-eight shape. At the same time, this installation method ensures that the angle after folding can be well positioned, so that the folding ladder is supported in a fixed figure-eight shape when opened.

[0036] See Figure 1-8The connecting assembly includes a steel plate 6, which has a hollow interior. End components are connected to both ends of the steel plate 6. Each end component includes an end plate 7 and a connecting cylinder 8. An installation slide rail 9 is provided on the end plate 7. A slider 10 matching the installation slide rail 9 is fixedly provided on the back of the connecting cylinder 8. Two threaded rods 11 are threadedly installed on the end plate 7. Threaded holes 12 matching the threaded rods 11 are provided on the steel plate 6. Rings 13 are fixedly provided at both the top and bottom of the connecting cylinder 8. Threaded grooves 14 are provided on the inner side of the rings 13, and threaded rods are fitted on the rings 13. 28. The inner side of the support leg 1 is provided with an inlet 15 for the connecting cylinder 8 to pass through. The inner side of the support leg 1 is also provided with a semi-circular opening 16 integrally formed with the inlet 15. The semi-circular opening 16 is for the connecting cylinder 8 to pass through. The front of the support leg 1 is provided with an installation opening 17. The threaded rod 28 is screwed into the threaded groove 14 of the ring 13 through the installation opening 17. The end plate 7 is installed on the steel plate 6 in conjunction with the threaded rod 11. Then the slider 10 on the back of the connecting cylinder 8 is slid in the installation slide rail 9 of the end plate to complete the installation between the steel plate 6, the end plate 7 and the connecting cylinder 8.

[0037] See Figure 1-8 An integrally formed protective side plate 19 is fixedly provided on the outer surface of the connecting cylinder 8. An integral through-hole 20 is provided on the protective side plate 19 and the connecting cylinder 8. A through-hole rod 21 is inserted into the through-hole 20. Two springs 18 are provided inside the connecting cylinder 8. A secondary mounting port 24 corresponding to the mounting port 17 is provided on the front of the support leg 1. A sealing element is inserted into the secondary mounting port 24. The sealing element includes a sealing plate 25. Two cylinders 26 are fixedly provided on the sealing plate 25. One end of the spring 18 is sleeved on the outer surface of the cylinder 26. The other end of the spring 18 abuts against the outer surface of the end plate 7. A sliding groove 27 for the through-hole rod 21 to pass through is also provided on the sealing plate 25.

[0038] The movable rod 23 is slidably set in the movable groove formed inside the hook plate 22 to ensure that the folding ladder can be opened in a figure-eight shape. The through rod 21 passes through the through hole 20 and through the sliding groove 27 on the sealing plate 25, so that the seal and the support leg do not separate. At this time, one end of the spring 18 is just sleeved on the outer surface of the cylinder 26. Due to the elasticity of the spring, the other end of the spring is finally pressed against the outer side of the end plate 7. After the installation of the sealing plate 25, the climbing steel plate 6, the end plate 7 and the connecting cylinder 8 as described above, the connecting cylinder 8 is then inserted into the support leg 1 through the through hole 15. Then the sealing plate 25 is inserted into the connecting cylinder 8. Finally, the threaded rod 28 passes through the installation hole 17, is inserted and screwed into the threaded groove 14 of the connecting cylinder 8 to complete the final installation.

[0039] See Figure 1-2 The support leg 1 is provided with a blocking component at the top and bottom. The blocking component includes a top cover 2 and a sealing cap 3 is fixedly provided at the bottom of the top cover 2. The sealing cap 3 is manually fastened into the end of the support leg 1. The total number of the connecting components is even. The size of the top cover 2 is larger than the size of the end of the support leg 1, so as to prevent external dust from entering the support leg and provide a good dustproof effect for the internal components of the support leg 1.

[0040] In practical operation, two sets of support legs 1, each with two support legs, form a stable figure-eight support structure, ensuring good overall support and improving the safety of workers during use. The support legs 1 are connected by connecting components, ensuring convenient connection and quick on-site installation. At the same time, auxiliary parts are used to connect the two connecting components at the top, ensuring that the entire folding ladder can be folded in half. When in use, the overall support is in a figure-eight shape, providing good support. When not in use, it can be folded together, ensuring convenient transportation and minimizing storage space, further improving the practicality of disassembling and folding the ladder.

[0041] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
