Description

Technical Field

[0001] The utility model relates to the technical field of folding ladders, in particular to a pedal for a rescue folding ladder which is easy to disassemble. Background Art

[0002] The two sides of the existing herringbone ladder are symmetrical. When opened to a certain angle, the two sides form the same oblique angle with the ground. At the same time, there is a certain angle between the ladder and the vertical working surface of the ground, which increases the distance between the operator and the working surface, resulting in an increase in the difficulty coefficient of the work, thereby affecting the work efficiency. Even if the ladder is rotated 90 degrees and placed so that one side of the ladder is parallel to the working surface, it is convenient for operation, but the other side of the ladder parallel to the working surface has no fixed support, and there is a risk of overturning during operation. In addition, most herringbone ladders use a simple hinged connection between the two ladder frames for folding, and are fixed with a folding support rod in the middle of the two ladder frames. This fixing method has a small force on the ladder and when it is overloaded, it will cause the ladder frame to shrink, which poses an operating risk to the operators. Among them, a new type of pedal folding straight ladder with application number "CN202021037970.6" is disclosed. The beneficial effects of the utility model are as follows: the second ladder frame is perpendicular to the supporting surface, which shortens the working distance, facilitates operation, and improves operation safety. The hinge mechanism is used to facilitate the opening and retraction of the ladder frame. At the same time, it has a self-locking function to enhance the stability and safety of the herringbone ladder. The first ladder frame main body is hinged with an anti-slip pedal, and the anti-slip pedals are hinged with two pedal pull rods for easy folding. The pedal is hinged between the first frame main body and the second frame main body. Although it can be stored and folded, the pedal and the frame of the straight ladder cannot be disassembled and installed according to use requirements, which makes it inconvenient to use in some rescue occasions due to site restrictions.
