[0028] It should be understood that, although the terms first, second, third, etc. may be used to describe various elements in the present disclosure, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of the present disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0029] like Figures 1 to 7As shown, the utility model provides a folding ladder, wherein the folding ladder 2 comprises a fixed vertical rod 3 and a movable vertical rod 4 respectively arranged on both sides, a plurality of support pedals 5 are evenly arranged between the fixed vertical rod 3 and the movable vertical rod 4, and the two ends of the support pedals 5 are respectively hingedly connected to the fixed vertical rod 3 and the movable vertical rod 4. By hingedly connecting the support pedals 5 to the fixed vertical rod 3 and the movable vertical rod 4, rapid folding and unfolding can be achieved, and the advantage of reducing the occupied volume can be achieved after folding.

[0030] like Figure 2 and Figure 3 As shown, the movable vertical rod 4 of the folding ladder can also be connected to the furniture 1 to realize linkage therewith. Specifically, the furniture 1 and the folding ladder 2 are movably connected by a sliding connection component, so that the folding ladder 2 can be unfolded and folded along with the up and down movement of the position of the furniture 1. At the same time, the upper and lower spaces of the furniture 1 can be flexibly changed, suitable for use in different scenes, and effectively meet multiple factors such as space utilization, operational convenience, use safety and user comfort to meet the needs of different users. The movable connection component includes a transverse slide 6 arranged on one side of the furniture 1, and the movable vertical rod 4 is connected to a pulley 7 at a position corresponding to the transverse slide 6. The pulley 7 is slidably arranged in the transverse slide 6 and slides and moves along the transverse slide 6. Therefore, by providing the transverse slide groove 6 and the pulley 7, when the height of the furniture 1 changes upward displacement, the pulley 7 simultaneously moves from one side of the transverse slide groove 6 to the other side, and the movable vertical rod 4 of the folding ladder 2 follows the direction of the pulley 7 to fold toward the side of the fixed vertical rod 3 to achieve folding; conversely, when the height of the furniture 1 changes downward displacement, the pulley 7 simultaneously moves from one side of the transverse slide groove 6 to the other side, and the movable vertical rod 4 of the folding ladder 2 follows the direction of the pulley 7 to move in the opposite direction of the fixed vertical rod 3 to achieve unfolding.

[0031] The folding and unfolding of the folding ladder 2 can be accomplished in a variety of ways. One is to directly pull the movable vertical rod or the supporting pedal. Another is to set an operating handle on one of the supporting pedals and realize the folding operation by turning the operating handle, such as Figure 4 Another method is to add a drive component, such as electric or pneumatic, to make the folding and unfolding of the folding ladder more convenient and quick, such as Figure 5As shown, the driving assembly is a telescopic rod 8, which is arranged at the bottom of the fixed vertical rod 3, one end of the telescopic rod 8 is connected to the fixed vertical rod 3, and the output end thereof is connected to the support pedal 5. Therefore, one side of the support pedal 5 is connected through the telescopic rod 8, and when the telescopic rod 8 is extended, the support pedal 5 is driven to rotate and unfold, and the movable vertical rod 4 connected to the support pedal 5 is correspondingly driven to move, thereby realizing the unfolding of the folding ladder 2; on the contrary, when the telescopic rod 8 is retracted, the support pedal 5 is driven to rotate and fold, and the movable vertical rod 4 connected to the support pedal 5 is correspondingly driven to move, thereby realizing the folding of the folding ladder 2.

[0032] like Figure 6 As shown, in order to further make the telescopic rod 8 self-adapt to the rotation of the support pedal 5, a rotating base 9 is provided between the fixed vertical rod 3 and the telescopic rod 8, and a U-shaped groove 10 for placing the telescopic rod 8 is provided in the middle of the rotating base 9, and the two sides of the bottom of the telescopic rod 8 are respectively rotatably connected to the U-shaped groove 10. Therefore, by rotatably setting the telescopic rod 8 on the rotating base 9, the telescopic rod 8 can be self-adaptively rotated in the process of extending or retracting, so as to avoid the occurrence of jamming due to the change of the rotation position of the support pedal 5 when the telescopic rod 8 is extended or retracted.

[0033] like Figure 6 As shown, the telescopic rod 8 is connected to the support pedal 5 via a connecting rod 11 , one end of the connecting rod 11 is hingedly connected to the telescopic rod 8 , and the other end of the connecting rod 11 is tiltedly connected and fixed to the support pedal 5 .

[0034] like Figure 3 As shown, in order to increase the supporting force of the movable vertical rod 4 on the furniture 1 and reduce the force simply relying on the pulley 7 and the slide 6, the movable vertical rod 4 is provided with a supporting block 12 on the side facing the furniture 1, and the upper end surface of the supporting block 12 abuts against the bottom of the furniture 1. In particular, when the folding ladder 2 is unfolded for use, the furniture 1 will exert a large force on the folding ladder 2, so it is necessary to provide the supporting block 12 to withstand the force exerted by the furniture 1, so as to make the whole more solid and reliable.

[0035] like Figure 7 As shown, in order to make the movable vertical rod 4 adapt to the uneven ground conditions when unfolded, an adjustment component is provided at the bottom of the movable vertical rod 4, and the adjustment component includes a support base 13 and a threaded adjustment rod 14. The support base 13 is movably connected to the bottom of the movable vertical rod 4 through the threaded adjustment rod 14. The support base 13 is adjusted through the threaded adjustment rod 14 so that its bottom can fit with the ground, so that the support pedal 5 can be kept level after the folding ladder 2 is unfolded.

[0036] Further, in order to protect the ground from being worn by the movable vertical rod 4, a protective pad 15 is provided at the bottom of the support base 13. Therefore, the bottom of the movable vertical rod 4 is wrapped by the protective pad 15, effectively preventing the ground from being worn and damaged.

[0037] like Figures 1 to 3 As shown, in order to facilitate the user to climb the folding ladder 2, a handrail 16 is provided at the upper end of the fixed vertical rod 3 and / or the movable vertical rod 4.

[0038] like Figure 6 As shown, in order to prevent the safety of the user when using the folding ladder 2, the upper surface of the support pedal 5 is provided with an anti-slip groove 17.

[0039] The above is only a preferred embodiment of the utility model. The utility model is not limited to the above implementation. As long as the technical effect of the utility model is achieved by the same means, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the scope of protection of the present disclosure. All should belong to the protection scope of the utility model. Within the protection scope of the utility model, its technical solution and / or implementation method can have various modifications and changes.
