[0002] Temporary barrier-free ramps can be used on various steps or in scenes with height differences to assist people with mobility difficulties or to transport goods with carts.

[0003] In the prior art, there are generally two types of ramps: one-piece and one-piece. The one-piece ramp is non-detachable, bulky, heavy, and inconvenient to transport and store. The detachable ramp has drawbacks such as excessive number of parts, insufficient stability, and poor load-bearing capacity. Utility Model Content

[0004] The utility model provides a foldable metal barrier-free ramp, which aims to overcome the above-mentioned shortcomings of the prior art and achieve higher stability and better load-bearing capacity with fewer parts.

[0005] The technical solution of this utility model is a foldable metal barrier-free ramp, comprising a horizontal step, an inclined step, and connecting plates. Several pairs of connecting plates are pivotally connected to each other, with each pair of connecting plates welded to the ends of a horizontal step. The outer sides of the two outermost pairs of connecting plates are pivotally connected to a pair of triangular connecting plates, each pair of triangular connecting plates welded to the ends of an inclined step. This structure allows the ramp to be folded and curled for transport and storage, and unfolded into a flat surface for use, with the ends supported at either high or low positions for walking.

[0006] Preferably, the connecting piece comprises a vertical main body, with outer protrusions and inner recesses formed on both sides of the lower portion of the main body, tilted toward both sides. The outer protrusions and inner recesses of adjacent connecting pieces are in contact and connected by screws and nuts. The outer protrusions or inner recesses of the connecting pieces at both ends are connected to a corner of an adjacent triangular connecting piece by screws and nuts. The upper portion of the connecting piece is formed with raised and recessed portions on both sides, and the raised and recessed portions of adjacent connecting pieces interlock. When in the open state, the connecting pieces and the triangular connecting piece rotate around the screws and nuts, and the raised and recessed portions of adjacent connecting pieces interlock, which can ensure good load-bearing and deployment integrity.

[0007] Preferably, the upper portion of the connecting piece is provided with two first connecting holes, and the lower portion of the connecting piece is provided with a second connecting hole, so as to facilitate connection with other expansion structures.

[0008] Preferably, the horizontal pedal comprises an integrally formed flat plate portion, anti-skid ridges, and a downwardly opening C-shaped portion. The top surface of the rectangular flat plate portion is provided with a plurality of anti-skid ridges parallel to the long sides at even intervals in the extension direction. The bottom surface of the flat plate portion is provided with a C-shaped portion provided in the extension direction. The end portion of the flat plate portion is partially welded to the first and second connection holes, and the C-shaped portion is welded around the outside of the second connection hole. The inclined pedal comprises an integrally formed flat plate portion and anti-skid ridges. The top surface of the rectangular flat plate portion is provided with a plurality of anti-skid ridges parallel to the long sides at even intervals in the extension direction. The end portion of the flat plate portion is welded to one side of the triangular connecting piece. The welded connection between the horizontal pedal and the connecting piece / triangular connecting piece ensures high structural strength, the provision of the anti-skid ridges increases friction, and the provision of the C-shaped portion further improves overall connection stability.

[0009] Preferably, the device further comprises a guardrail and a support rod, wherein the bottom end of the guardrail is connected to a plug-in component which is plugged into a connecting piece, the bottom end of the support rod is supported on the ground, the top end of the support rod is connected to the plug-in component which is plugged into the bottom of the connecting piece, and the plug-in component and the connecting piece are fixed together by screws and nuts. This can improve safety when the height difference is large.

[0010] The advantages of this utility model are: reasonable structural design, the pedals are welded to the connecting pieces, which can ensure high structural stability, the connecting pieces are directly plugged into each other, which can further improve the structural stability, and they will not be squeezed and deflected when heavy objects pass through, thereby improving the integrity of load-bearing and deployment, and can be preferably connected to the bottom support rod and guardrail to meet application scenarios with larger height differences.

[0017] like Figure 1-3 As shown, a foldable metal barrier-free ramp has a structure including a horizontal pedal 1, an inclined pedal 2 and a connecting piece 3, wherein several pairs of connecting pieces 3 are rotatably connected to each other, and each pair of connecting pieces 3 is welded to the two ends of a horizontal pedal 1, and the outer sides of the two outermost pairs of connecting pieces 3 are respectively rotatably connected to a pair of triangular connecting pieces 21, and each pair of triangular connecting pieces 21 is welded to the two ends of a inclined pedal 2.

[0018] When transporting and storing, the whole can be folded and curled. When in use, the horizontal pedal 1 and the inclined pedal 2 are opened to make the ramp as a whole be arranged in a plane, with the two ends supported at two high and low positions respectively, so that people can walk on it.

[0019] The connecting piece 3 includes a vertical main body 31, and the two sides of the lower part of the main body 31 are respectively formed with an outer protrusion 32 and an inner recess 33 inclined to both sides. The outer protrusions 32 and inner recesses 33 of adjacent connecting pieces 3 are in contact with each other and are connected by screws and nuts 4. The outer protrusions 32 or inner recesses 33 of the connecting pieces 3 at both ends are connected to a corner of the adjacent triangular connecting piece 21 by screws and nuts 4. The upper part of the connecting piece 3 is respectively formed with a protrusion 34 and a recess 35. The protrusions 34 and recesses 35 of adjacent connecting pieces 3 are plugged into each other. Two first connecting holes 36 are opened on the upper part of the connecting piece 3, and a second connecting hole 37 is opened on the lower part of the connecting piece 3.

[0020] The horizontal pedal 1 includes an integrally formed flat plate portion 11, anti-slip ridges 12 and a downwardly opening C-shaped portion 13. The top surface of the rectangular flat plate portion 11 is evenly spaced with several anti-slip ridges 12 parallel to the long sides in the extension direction. The bottom surface of the flat plate portion 11 is provided with a C-shaped portion 13 arranged in the extension direction.
