[0031] See also Figure 1 , 2a 2b, the figure shows the use state of the subway platform door front cover plate support mechanism of the present invention on the platform door front cover plate 100, two groups of support mechanisms are arranged on the front cover plate 100, wherein the first fixed support 1 and the second fixed support 2 of each group of support mechanisms are arranged on the inner surface of the front cover plate 100 of the platform door, and the distance between them is approximately the length of the support rod 4, Figure 1 The support rod 4 is in the retracted state, that is, the free end of the support rod 4 is connected to the second fixed support 2, and the front cover is closed. Figure 2a , 2b The front cover is in the open state. At this time, the support rod 4 rotates from the horizontal direction to the vertical direction, and its free end 42 is engaged with the third fixed support 3, thereby keeping the front cover in the open state, that is, the free end 42 of the support rod 4 can be connected to the second fixed support 2 and the third fixed support 3 respectively, thereby realizing the conversion between the closed and open states of the front cover 100.
[0032] Specifically, see Figure 5 The first connecting shaft 43 is provided at the fixed end 41 of the support rod 4 in a direction perpendicular to the length of the support rod.
