[0023] 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.

[0024] Example 1

[0025] Combination Figures 1-7 A herringbone-shaped fiberglass insulated ladder includes a first upright 1, a second upright 2, a third upright 3, and a fourth upright 4. Its features include: a folding mechanism 5 between each of the first upright 1 and the second upright 2, and between the third upright 3 and the fourth upright 4; the folding mechanism 5 includes several first pedals 501 and several second pedals 502, with an outer irregular seat 503 fixedly installed at one end of each of the first pedals 501 and the second pedal 502; several connecting seats 504 are fixedly installed side-by-side inside each of the first upright 1, the second upright 2, the third upright 3, and the fourth upright 4; a first rotating shaft 505 is rotatably installed through the outer irregular seat 503 and the connecting seat 504; an inner irregular seat 506 is fixedly installed at the other end of each of the first pedals 501 and the second pedal 502; a folding seat 507 is rotatably installed between the two inner irregular seats 506; and two second rotating shafts 508 are rotatably installed through the two inner irregular seats 506 and the folding seat 507.

[0026] See Figures 2-4 Furthermore, it is found that a cuboid is fixedly installed on the lower part of one side of the outer irregular seat 503 and the upper part of one side of the inner irregular seat 506. The upper and lower sides of the connecting seat 504 are provided with protrusions. The outer irregular seat 503 and the inner irregular seat 506 are both composed of several irregular blocks arranged side by side, and the outer irregular seat 503 and the inner irregular seat 506 are adapted to the connecting seat 504 and the folding seat 507 respectively.

[0027] Specifically, by applying downward pressure to the folding seat 507, the first pedals 501 and the second pedals 502 on both sides can rotate around the connecting seat 504. Since the first pedals 501 and the second pedals 502 are respectively provided with an outer irregular seat 503 and an inner irregular seat 506, and since both the outer irregular seat 503 and the inner irregular seat 506 are provided with cuboids, when the first pedals 501 and the second pedals 502 are aligned, the outer irregular seat 503 and the inner irregular seat 506 act on the connecting seat 504 and the folding seat 507 respectively, fixing the first pedals 501 and the second pedals 502. When an upward force is applied to the folding seat 507, the first pedals 501 and the second pedals 502 on both sides rotate in opposite directions around the connecting seat 504, thus completing the storage of the first pedals 501 and the second pedals 502.

[0028] Example 2

[0029] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 A tie rod 6 is fixedly installed between pole 1 and pole 4, and between pole 2 and pole 3. A connecting mechanism 7 is provided between pole 1, pole 2, pole 3 and pole 4. The connecting mechanism 7 includes a first rotating seat 701 and a second rotating seat 702. The first rotating seat 701 is fixedly installed on pole 1 and pole 2 respectively, and the second rotating seat 702 is fixedly installed on pole 3 and pole 4 respectively. A third rotating shaft 703 is rotatably installed through the first rotating seat 701 and the second rotating seat 702. A fourth rotating shaft 704 is fixedly installed inside pole 1, pole 2, pole 3 and pole 4. A support seat 705 is sleeved on the outside of the fourth rotating shaft 704. A rubber pad 706 is fixedly installed on the lower part of the support seat 705.

[0030] See Figure 2 Furthermore, based on Embodiment 1, it is further found that the No. 1 rotatable seat 701 is adapted to be matched with the No. 3 upright 3 and the No. 4 upright 4 respectively, the No. 2 rotatable seat 702 is adapted to be matched with the No. 1 upright 1 and the No. 2 upright 2 respectively, the support seat 705 is embedded and rotatably installed inside the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3 and the No. 4 upright 4, and the rubber pad 706 is located outside the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3 and the No. 4 upright 4.

[0031] Specifically, the No. 1 rotating seat 701 and the No. 2 rotating seat 702 act on the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3, and the No. 4 upright 4, allowing the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3, and the No. 4 upright 4 to rotate around an axis, thereby achieving the opening and closing effect of the ladder. At the same time, the support seat 705 is rotatably connected to the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3, and the No. 4 upright 4 through the fourth rotating shaft 704, so that the rubber pad 706 is always flush with the ground, further reducing the wear of the rubber pad 706 on the ground.

[0032] In actual operation, by applying downward pressure to the folding seat 507, the first pedals 501 and the second pedals 502 on both sides can rotate around the connecting seat 504. Since the first pedals 501 and the second pedals 502 are respectively provided with an outer irregular seat 503 and an inner irregular seat 506, and since both the outer irregular seat 503 and the inner irregular seat 506 are provided with cuboids, when the first pedals 501 and the second pedals 502 are aligned, the outer irregular seat 503 and the inner irregular seat 506 act on the connecting seat 504 and the folding seat 507 respectively, fixing the first pedals 501 and the second pedals 502. When an upward force is applied to the folding seat 507, the first pedals 501 and the second pedals 502 on both sides rotate in opposite directions around the connecting seat 504, thus completing the storage of the first pedals 501 and the second pedals 502.

[0033] The No. 1 rotating seat 701 and the No. 2 rotating seat 702 act on the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3, and the No. 4 upright 4, allowing the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3, and the No. 4 upright 4 to rotate around an axis, thereby achieving the opening and closing effect of the ladder. At the same time, the support seat 705 is rotatably connected to the No. 1 upright 1, the No. 2 upright 2, the No. 3 upright 3, and the No. 4 upright 4 through the fourth rotating shaft 704, so that the rubber pad 706 is always flush with the ground, further reducing the wear of the rubber pad 706 on the ground.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
