The first connecting plate of the second reinforcing member 510 is connected to the pedal reinforcing plate 400 and the triangular bracket 100, and the second connecting plate is engaged with the plastic kick plate 300, so that the connection of the triangular bracket 100, the pedal reinforcing plate 400 and the plastic kick plate 300 is realized through the second reinforcing member 510.

[0063] Specifically, Figure 2 , Figure 3 as well as Figure 10 As shown, the first connecting plate is connected to the supporting portion 410 of the pedal reinforcing plate 400 .

The second mounting boss extends into the second positioning hole and is clamped to the second connecting plate, thereby realizing the connection between the second reinforcement 510 and the plastic kick plate 300.

[0066] More specifically, in this embodiment, the structure of the second mounting boss is the same as that of the first mounting boss 600 . In other embodiments, the structure of the second mounting boss is different from that of the first mounting boss 600 , as long as the snap connection can be achieved.

[0067] Specifically, the first reinforcing member 500 and the second reinforcing member 510 are integrally cast sheet metal parts.

[0068] Further, as Figures 1 to 3 , and Figure 11 shown, a combined escalator plastic step further includes a kick plate reinforcement plate 700, one end of which is connected to the side of the plastic kick plate 300 facing away from the second reinforcement member 510, and the other end is connected to the triangular bracket 100. By providing the kick plate reinforcement plate 700 to connect the plastic kick plate 300 and the triangular bracket 100, the installation stability of the plastic kick plate 300 is improved, and the structural strength of the combined escalator plastic step is enhanced.

[0069] Specifically, as Figures 1 to 3 , and Figure 11 shown, the kick plate reinforcement plate 700 includes a connected first reinforcement portion 710 and a second reinforcement portion 720. The first reinforcement portion 710 is in snap-fit connection with the plastic kick plate 300, the second reinforcement portion 720 is connected to the triangular bracket 100, and one end of the first reinforcement portion 710 facing away from the second reinforcement portion 720 is bent towards the direction close to the triangular bracket 100.

[0071] Further, as Figure 1 shown, reinforcing ribs 900 are provided on the side of the plastic tread 200 and / or the plastic kick plate 300 close to the triangular bracket 100. By providing the reinforcing ribs 900 on the back of the plastic tread 200 and / or the plastic kick plate 300, the anti-deformation ability and structural strength of the plastic tread 200 and / or the plastic kick plate 300 are increased.

[0072] Specifically, in this embodiment, reinforcing ribs 900 are provided on the backs of both the plastic tread 200 and the plastic kick plate 300, and the reinforcing ribs 900 provided on the back of the plastic tread 200 and the reinforcing ribs 900 provided on the back of the plastic kick plate 300 have different structures.

[0073] In other embodiments, the structures of the reinforcing ribs 900 provided on the backs of the plastic tread 200 and the plastic kick plate 300 may be the same, and the specific structure of the reinforcing ribs 900 is determined according to actual operation needs.

[0074] In some embodiments, the plastic tread 200 and / or the plastic kick plate 300 are of an integral plate structure.

[0075] Furthermore, in this embodiment, the plastic pedal 200 includes at least two pedal sections; and / or, the plastic kick plate 300 includes at least two kick plate sections. That is, the plastic pedal 200 and / or the plastic kick plate 300 can be spliced to avoid bending and deformation during molding. At the same time, parts can be locally replaced during maintenance according to the damage situation, avoiding waste. In addition, by increasing or decreasing the number of the plastic pedal 200 and / or the plastic kick plate 300, various escalator width specifications can be compatible, improving the versatility of the plastic pedal 200 and / or the plastic kick plate 300.

[0076] Furthermore, as Figure 1 shown, the combined plastic escalator step further includes a boundary strip 800, and the boundary strip 800 is arranged around the circumference of the plastic pedal 200. By arranging the boundary strip 800 around the plastic pedal 200, the boundary of the plastic pedal 200 can be warned and distinguished, improving the safety of passengers taking the escalator.

[0077] Specifically, the color of the boundary strip 800 is different from that of the plastic pedal 200.

[0078] In summary, for the combined plastic escalator step of the present application, the materials of the plastic pedal 200, the plastic kick plate 300, and the boundary strip 800 are all plastics, which can further reduce the weight of the step. The triangular bracket 100, the first reinforcing member 500, the pedal reinforcing plate 400, the kick plate reinforcing plate 700, and the second reinforcing member 510 are all sheet metal parts, which are connected by fasteners to form the overall step frame, ensuring that the step has sufficient strength and rigidity.
