[0037] See also Figures 1 to 4 , the utility model provides a technical solution: a folding escalator with a reinforcement structure, comprising: a folding mechanism, a front support mechanism 4 and a rear support mechanism 5;

[0038] The folding mechanism comprises a first connecting rod 1, a second connecting rod 2 and a limit stopper 3;

[0041] When the folding escalator is in the open state, the first connecting rod 1 is at an inclined angle with the front lower and the back higher, and the second connecting rod 2 is at a horizontal angle;

[0042] There are four limit blocks 3, which are respectively arranged on both sides of the front support mechanism 4 and both sides of the rear support mechanism 5. The limit blocks 3 are used to limit the rotation angle of the first connecting rod 1;

[0043] A reinforcement structure 8 is fixedly connected below the footrests 6 of the front support mechanism 4 and the rear support mechanism 5 .

[0044] It should be noted that the front support mechanism 4 and the rear support mechanism 5 each include two support legs 7 and four foot pedals 6, the foot pedals 6 are fixedly connected between the two support legs 7, and the support legs 7 of the front support mechanism 4 are longer than the support legs 7 of the rear support mechanism 5, so that the staff has higher safety when climbing the ladder;

When the folding escalator of the embodiment of the present application is in the open state, the vertical cross-section of the end of the first connecting rod 1 is semicircular, and the first connecting rod 1 is in an inclined state with the front lower and the rear higher. The limit stopper 3 located at the front support mechanism 4 is distributed at the lower end of the first connecting rod 1, and the limit stopper 3 located at the rear support mechanism 5 is located at the upper end of the first connecting rod 1, thereby preventing the first connecting rod 1 from rotating in the horizontal direction, and preventing the folding ladder from being stretched out after being subjected to a high weight, causing a dangerous situation;

[0046] The reinforcement structure 8 is disposed below the foot pedal 6 to increase the supporting force of the foot pedal 6 , thereby increasing the structural strength and durability of the foot pedal 6 .

[0050] As a further improvement, the folding handrail ladder provided by the embodiment of the present application further includes two pairs of folding handrails; the folding handrails are connected to the upper part of the front support mechanism 4.

[0051] Specifically, by setting the folding handrails, it is beneficial for the staff to use the escalator more conveniently and safely, and the folding handrails can be folded and stored when the escalator is stored, reducing the occupied space.

When the armrest rod 13 is in the open state, the limiting elastic piece 14 has a limiting force on the armrest rod 13, which can prevent the armrest rod 13 from closing, thereby improving the safety and convenience of using the armrest rod 13.

[0057] As a further improvement, a horizontal pedal 15 is connected to the upper end surface of the second connecting rod 2 of the folding armrest ladder provided by the embodiment of the present application, so as to provide a larger platform area for the staff and improve the safety and convenience of use.
