[0030] The cross beam 1 is fixedly arranged at the inner side of the shed folding frame 100 through the connecting bolts A13 at the two sides, when the shed plate is connected, the hanging plate 2 is hung to the top of the cross beam 1 through the pulleys 3, the pulleys 3 are slidably arranged at the inner side of the sliding groove 11, the vertical plate 21 is tightly attached to one side of the cross beam 1, the shed plate is adjusted to the position required to be installed through the sliding of the pulleys 3 in the sliding groove 11, then the fixing bolt 4 is rotated to screw with the hanging plate 2, the clamping beam 41 is driven to move downwards, the clamping beam 41 is moved to the inner side of the sliding groove 11 and is tightly matched with the sliding groove 11, at this time, the fixing bolt 4 is continuously rotated to screw with the hanging plate 2, the hanging plate 2 is driven to move away from the cross beam 1, so that the two pulleys 3 are separated from the sliding groove 11, finally the connecting bolt B224 is screwed with the shed plate through the connecting hole 223, the shed plate connecting plate 22 is connected with the shed plate, so that the shed plate is conveniently installed at the bottom of the cross beam 1.

[0031] With reference to Figure 2 , Figure 3 and Figure 6 , a flower hole 23 is formed in the top of the hanging plate 2 and corresponds to the pair of pulleys 3, the pulleys 3 are rotatably arranged at the inner side of a wheel frame 31, a flower shaft 32 is fixedly arranged at the top of the wheel frame 31 and is matched with the flower hole 23, and a connecting bolt C33 is screwedly arranged at the inner side of the flower shaft 32.

[0033] With reference to Figure 4 and Figure 5 , a matching surface 411 is arranged at the bottom of the clamping beam 41 and is matched with the sliding groove 11.

[0034] By mating the mating surface 411 with the slide groove 11, the clamping beam 41 fits more tightly with the slide groove 11, thereby making the connection between the hanging plate 2 and the crossbeam 1 more secure.

[0035] Reference Figure 2 and Figure 3 The bottom of the crossbeam 1 is provided with an inclined surface 12. The side of the shelf connecting plate 22 near the inclined surface 12 is provided with a bending part 221.

By setting the reinforcing plate 24, the strength of the connection between the vertical plate 21 and the shelf connecting plate 22 is increased.

[0037] In summary, the connecting assembly for the canopy panel of the urban rail passenger vehicle passageway disclosed in this application is used by hanging the hanging plate 2 on the top of the crossbeam 1 via the pulley 3, so that the pulley 3 is slidably set inside the slide groove 11, and the vertical plate 21 is tightly attached to one side of the crossbeam 1. The canopy panel is adjusted to the required installation position by sliding the pulley 3 inside the slide groove 11. Then, by rotating the fixing bolt 4, the fixing bolt 4 is threadedly engaged with the hanging plate 2, which drives the clamping beam 41 to move downward, so that the clamping beam 41 moves to the inside of the slide groove 11 and is tightly engaged with the slide groove 11. At this time, the fixing bolt 4 is rotated again, so that the fixing bolt 4 is threadedly engaged with the hanging plate 2, which drives the hanging plate 2 to move away from the crossbeam 1, thereby driving the two pulleys 3 to disengage from the slide groove 11. Finally, the connecting bolt B224 passes through the connecting port 223 and is threadedly engaged with the canopy panel, so that the canopy panel connecting plate 22 is connected to the canopy panel, thus completing the connection of the canopy panel.
