It not only makes it more convenient to fold and unfold, but also can hide the steps when folded, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a concealable staircase for street-facing houses, comprising a U-shaped frame, two rotating pedal assemblies are provided between the two vertical rods of the U-shaped frame, the left and right ends of the two rotating pedal assemblies are connected to the U-shaped frame through a connecting short shaft, a foldable L-shaped pulling member is provided on both sides of the upper rotating pedal assembly and on both sides of the upper end of the U-shaped frame, the longitudinal length of the lower rotating pedal assembly is twice the longitudinal length of the upper rotating pedal assembly, a vertical pulling rod is connected between the two sides of the two rotating pedal assemblies through a pin shaft, and a lower end closing plate is provided on the lower surface of the lower rotating pedal assembly.

[0005] Furthermore, the rotating pedal assembly includes a support frame, and a step pedal is welded on the front side of the upper surface of the support frame. The rotating pedal assembly can be rotated by connecting a short shaft, thereby facilitating the folding of the rotating pedal assembly.

[0006] Furthermore, a fixed clamping piece is provided between the lower end closing plate and the U-shaped frame, and a clamping groove and a clamping buckle are fixed on the fixed clamping piece. A clamping buckle is provided at the edge of the upper surface of the lower end closing plate, and a clamping groove corresponding to the clamping buckle is provided at the upper end of the front surface of the U-shaped frame. When the device is folded up, it is fixed between the clamping groove and the clamping buckle, thereby facilitating the folding of the rotating pedal assembly and hiding the steps.

[0007] Furthermore, mounting ear plates are fixed to the four corners of the U-shaped frame, and mounting through holes are provided on the mounting ear plates. The device can be installed into the groove reserved at the steps of the house through the mounting through holes on the mounting ear plates.

[0008] Furthermore, the lower surface of the lower end closing plate is connected to a handle via a hinge seat, and the handle is a U-shaped structure. The rotating pedal assembly below can be pulled open by the handle to facilitate unfolding of the steps.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the rotating pedal assembly can be rotated by connecting the short shaft, so as to facilitate the folding of the rotating pedal assembly; the device can be installed in the groove reserved at the steps of the house through the mounting through hole on the mounting ear plate; the rotating pedal assembly below can be pulled open by the handle, so as to facilitate the unfolding of the steps; when unfolding, the rotating pedal assembly can be pulled upward by the vertical pull rod and the foldable L-shaped pull piece, so that the rotating pedal assembly can be horizontal; when the device is folded, it is fixed between the card slot and the card buckle, so as to facilitate the folding of the rotating pedal assembly, thereby hiding the steps; the rotating pedal assembly is covered by the lower end closing plate when the steps are folded; the concealable steps for the street-facing house are simple in structure and easy to operate, which not only makes folding and unfolding more convenient, but also allows the steps to be hidden when folded.
