Specifically, the connecting frame 100, the pedal 300, the supporting leg 200, the connecting rod 500 and the supporting frame 400 are all made of aluminum plates or hard plastic steel, so that the overall strength of the folding step ladder can be ensured, and the quality of the folding step ladder can be reduced.

It can be understood that referring to fig. 5 and 6, the magnetic component 700 is disposed between the support 400 and the connection frame 100, and after the support 400 and the connection frame 100 are relatively contracted, the relative position of the support 400 and the connection frame 100 can be fixed under the adsorption action of the magnetic component 700, that is, the folding step ladder can be kept in a folded state, which is beneficial to hiding and storing the folding step ladder.

Specifically, the magnetic attraction assembly 700 includes a first magnetic block and a second magnetic block with opposite magnetic poles, where the first magnetic block and the second magnetic block are respectively connected to opposite surfaces of the connection frame 100 and the support frame 400, and when the support frame 400 is contracted relative to the connection frame 100, the first magnetic block and the second magnetic block are arranged relatively, so that the first magnetic block and the second magnetic block are mutually attracted, and thus the relative positional relationship between the support frame 400 and the connection frame 100 is fixed.

It should be appreciated that in other embodiments, the folding step ladder may be used in a bathroom cabinet, the upper end of the bathroom cabinet is connected with a sink, the folding step ladder is connected to the cabinet door of the bathroom cabinet, a shorter child may turn the folding step ladder over to ground after opening the bathroom cabinet, and the child steps on the folding step ladder to reach the sink above the bathroom cabinet, thereby completing the washing by itself.

It will be appreciated that in other embodiments the folding steps may be used with an elevated bed in a bedroom, the folding steps may be connected to a mounting surface such as a wall surface, and the user may fold the folding steps to reduce the amount of space taken by the user by unfolding the folding steps to form a stair passageway connecting the elevated bed to the ground to facilitate the user getting on and off the bed when not in use.

The foregoing description of the preferred embodiments of the present utility model should not be construed as limiting the scope of the utility model, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model as defined by the following description and drawings or any application directly or indirectly to other relevant art(s).

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
