[0027] Example 1

[0028] like Figure 1-6 As shown, the utility model provides a subway passenger information display terminal, including a bottom plate 1, a support rod 2, an adjustment device, a mounting frame 4, a display screen 5, a fixing frame 6, a mounting groove 7, and a cleaning device. The support rod 2 is fixedly connected to the upper end of the bottom plate 1, the adjustment device is arranged at the upper end of the support rod 2, the mounting frame 4 is movably mounted on the side of the support rod 2 through the adjustment device, the display screen 5 is arranged on the front of the mounting frame 4, the fixing frame 6 is fixedly connected to the outer wall of the mounting frame 4, the mounting groove 7 is opened on the front of the mounting frame 4, and the cleaning device is arranged inside the fixing frame 6 and the mounting groove 7; the cleaning device includes a motor A801, a threaded rod 802, a moving block 803, a receiving groove 804, a motor B805, a bevel gear A806, Bevel gear B807, rotating rod 808, cleaning roller 809; motor A801 ​​is fixedly connected to the inside of the mounting groove 7, threaded rod 802 is fixedly connected to the output end of motor A801, moving block 803 is threadedly connected to the outer wall of threaded rod 802, accommodating groove 804 is opened in the inside of moving block 803, motor B805 is fixedly connected to the outer wall of moving block 803, bevel gear A806 is fixedly connected to the output end of motor B805, bevel gear B807 is meshed with the side of bevel gear A806, rotating rod 808 is fixedly connected to the outer wall of bevel gear B807, the other end of rotating rod 808 passes through moving block 803 through a bearing, and the upper end of cleaning roller 809 is fixedly sleeved on the outer wall of rotating rod 808.

[0029] The length of the cleaning roller 809 is smaller than the inner length of the fixed frame 6 , thereby ensuring that the cleaning roller 809 can be received in the interior of the fixed frame 6 .

[0030] The length of the cleaning roller 809 is longer than the upper end of the display screen 5 , thereby ensuring that the cleaning roller 809 can clean the entire display screen 5 .

[0031] The side of the cleaning roller 809 close to the display screen 5 is in close contact with the display screen 5 during cleaning.

[0032] The outer wall of one side of the moving block 803 located inside the installation groove 7 is tightly fitted with the inner wall of the installation groove 7, thereby preventing the moving block 803 from rotating with the threaded rod 802.

[0033] In this embodiment, by providing a cleaning device, the surface of the display screen 5 can be regularly cleaned by a cleaning roller 809, thereby ensuring the cleanliness of the display screen 5.
