DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a multifunctional ladder for building decoration, comprising two sets of lower ladders 1 and two sets of upper ladders 2, the upper end of the lower ladder 1 is movably connected to the lower end of the upper ladder 2, and the upper ends of the two sets of upper ladders 2 are movably connected through a connecting block 3;

[0028] The two sets of lower ladders 1 and the two sets of upper ladders 2 are arranged in a mirror image, and the upper ladders 2 are installed on the inner side of the lower ladders 1;

[0029] A plurality of climbing rods 5 are provided inside the lower ladder 1 and the upper ladder 2;

[0030] Both sides of the lower ladder 1 near the upper end and the upper ladder 2 near the lower end are provided with a rotation hole 11, and the rotation hole 11 is rotatably connected through a first rotating shaft 12;

[0031] A first stop hole 13 is provided below the rotation hole 11 of the lower ladder 1, and a second stop hole 14 corresponding to the first stop hole 13 is provided below the rotation hole 11 of the upper ladder 2. A nut block 15 is fixedly provided outside the first stop hole 13, and a first bolt 4 is threadedly connected inside the nut block 15. The first bolt 4 passes through the first stop hole 13 and the second stop hole 14.

[0032] The lower ladder 1 and the upper ladder 2 can rotate relative to each other through the first rotating shaft 12. When the first bolt 4 is inserted into the second stop hole 14, the lower ladder 1 and the upper ladder 2 cannot rotate, which facilitates switching between various forms.

[0033] The connecting block 3 is provided with a second rotating shaft 31 at both ends, and the upper ladder 2 is provided with a through hole matching the second rotating shaft 31 near the upper end, and the second rotating shaft 31 is rotatably connected to the through hole;

[0034] A boss 32 is provided on the inner side of the connecting block 3. The boss 32 is approximately T-shaped. Arcs 33 are provided on both sides of the boss 32. A rounded corner is provided on the upper end of the upper ladder 2. The arc 33 is tangent to the rounded corner.

[0035] Threaded holes are provided on both sides of the upper end of the boss 32, and second bolts 6 are provided in the threaded holes;

[0036] A support rod 7 is provided on the inner side of the lower ladder 1 near the upper end.

[0037] The lower ladder 1, the upper ladder 2 and the connecting block 3 can be transformed into a climbing ladder, a stepladder and a supporting frame by changing the connection mode.

[0038] Through the second rotating shaft 31, the upper ladder 2 and the connecting block 3 can rotate with each other. When the second bolt 6 is locked, the second bolt 6 squeezes the upper ladder 2 to prevent the upper ladder 2 and the connecting block 3 from rotating, which is convenient for switching between various forms. The T-shaped boss 32 can limit the upper ladder 2 to prevent the upper ladder 2 and the connecting block 3 from excessive rotation. In addition, in the support frame form, the support rod 7 can support the upper ladder 2.

[0039] The working principle and use process of the utility model: the lower ladder 1, the upper ladder 2 and the connecting block 3 can be transformed into a climbing ladder, a herringbone ladder and a supporting frame after the connection mode is changed;

[0040] Storage: Figure 2 When the device is in the folded state, the first stop hole 13 and the second stop hole 14 are coaxial, the first bolt 4 is screwed to the bottom, and the bolt 4 simultaneously penetrates the first stop hole 13 and the second stop hole 14. At this time, the upper ladder 2 cannot rotate through the first rotating shaft 12, the lower ladder 1 and the upper ladder 2 are in a relatively fixed state, the second bolt 6 squeezes the rounded corner of the upper end of the upper ladder 2, the second rotating shaft 31 cannot rotate, and the two sets of upper ladders 2 are also in a closed state. When the device is folded, it is easy to carry and transport, and can also save space;

[0041] Herringbone ladder: Figure 3 When it is necessary to use the herringbone ladder, when the device is stored, loosen the second bolt 6 to disengage the second bolt 6 from the upper ladder 2. At this time, the second shaft 31 can rotate, and then open the bottom of the lower ladder 1, so that the two sets of lower ladders 1 and upper ladders 2 rotate through the second shaft 31, so that the device is in a herringbone shape, and then tighten the second bolt 6 to support the lower end of the lower ladder 1 on the ground for use.

[0042] Ladder: Figure 4 When the ladder form needs to be used, in the storage state, loosen the second bolt 6 to disengage the second bolt 6 from the upper ladder 2. At this time, the second rotating shaft 31 can rotate, and then open the lower ladder 1 and the upper ladder 2, so that the two sets of lower ladders 1 and upper ladders 2 are rotated 90 degrees through the second rotating shaft 31, so that the device is in a straight line shape, and then tighten the second bolt 6, support the lower end of the lower ladder 1 on the ground, and put the lower ladder 1 at the other end on the wall for use.

[0043] Support frame: Figure 5When the support frame form is needed, in the storage state, the first bolt 4 and the second bolt 6 are loosened respectively to make the first bolt 4 and the second bolt 6 detach from the upper ladder 2. At this time, the first rotating shaft 12 and the second rotating shaft 31 can rotate, and then the two sets of lower ladders 1 are moved outward, and the two sets of upper ladders 2 are rotated and folded inward to make the upper ladder 2 in a horizontal state. The support rod 7 arranged on the inner side of the lower ladder 1 near the upper end can support the upper ladder 2, and the T-shape of the boss 32 can also support the two sets of upper ladders 2 to prevent the middle part of the support frame form from collapsing downward.
