The lower end of the ceiling bracket 1 is fixed with a connecting rod 2, and the top of the ceiling bracket 1 is fixed to the top of the subway. The lower end of the connecting rod 2 is movably connected to the movable arm 3, and the adjusting wheel 4 passes through the center of both ends of the movable arm 3. The lower end of the movable arm 3 is movably connected to a vertical rod 5, and the lower end of the vertical rod 5 is fixed with a pull plate 6 that can be pulled and adjusted. The center of both sides of the pull plate 6 is penetrated by a fixed shaft 61, and the two fixed shafts 61 are each fixed with a sleeve 62 along the front and back of the pull plate 6.

[0022] Example 2

[0023] Based on Embodiment 1, connecting seats 7 for installing advertising display screens are fixed on both sides of the lower end of the pull plate 6, and movable seats 71 for movably installing advertising display screens are fixed at the lower end of the connecting seats 7. The pull plate 6 serves as an adjustable component, and its lower end is equipped with connecting seats 7 and movable seats 71 for installing advertising display screens. When the pull plate 6 is adjusted by the adjustment system, the advertising display screen is adjusted synchronously to meet the angle adjustment requirements of the advertising display screen during installation, ensuring that the entire advertising display screen can effectively integrate with the entire subway internal facilities. The components are designed to be compatible and meet the installation requirements for advertising. The outer walls of the sleeve 62 and the adjusting wheel 4 are wrapped with cables 8. The adjusting wheel 4 and the sleeve 62 on the pull plate 6 form an angle adjustment structure through the cables 8. When the user needs to adjust the placement angle of the pull plate 6, the adjusting wheel 4 can be rotated. The adjusting wheel 4 drives the cables 8 to retract, thereby pulling the pull plate 6 to rotate to one side. At the same time, since the movable arm 3 and the upright 5 are movably connected, the adjustment needs of the advertising display screen can be met. This type of operating component is simple to operate, convenient and practical. At the same time, the pulling component is manually adjustable, reducing the difficulty of adjustment during installation.

[0024] Example 3

[0025] Based on Embodiment 2, a movable shaft 44, which moves back and forth, runs through the middle of the inner wall of the adjusting wheel 4. Locking gears 42 are keyed to both sides of the movable shaft 44. A friction baffle 41 is installed on the inner wall of the adjusting wheel 4, and the friction baffle 41 is frictionally fastened to the movable arm 3. A connecting groove 43 matching the locking gear 42 is opened in the middle of the inner wall of the friction baffle 41. When one adjusting wheel 4 pulls, it separates one friction baffle 41 from one locking gear 42, and the movable shaft 44 drives the other locking gear 42 to engage with the other friction baffle 41. One adjusting wheel 4 clockwise winds up the cable 8. One side adjustment wheel 4 retracts the cable 8 counterclockwise. This adjustment system adopts a two-way adjustment structure design. When the user needs to adjust the advertising display screen according to the subway landscape, he can pull the adjustment wheel 4. One side adjustment wheel 4 pulls the friction baffle 41 on one side to separate from the locking gear 42 on one side. The movable shaft 44 drives the locking gear 42 on the other side to fit into the friction baffle 41 on the other side. At the same time, one side adjustment wheel 4 is rotated counterclockwise. The friction baffle 41 on one side adjustment wheel 4 separates from the movable shaft 44, and the friction baffle 41 on the other side connects to the movable shaft 44, so as to meet the user's needs to adjust the left and right advertising display screens.

[0026] In actual use, the top of the ceiling bracket 1 is fixed to the top of the subway. At this time, the connecting seat 7 and the movable seat 71 are connected to the advertising display screen by bolts. By rotating the adjusting wheel 4, the adjusting wheel 4 drives the cable 8 to retract, thereby pulling the pulling plate 6 to rotate to one side. At the same time, since the movable arm 3 and the upright 5 are movably connected, when the user needs to adjust the advertising display screen according to the subway landscape, the adjusting wheel 4 can be pulled. One adjusting wheel 4 pulls the friction baffle 41 of one side to separate from the locking gear 42 of one side. The movable shaft 44 drives the locking gear 42 of the other side to fit into the friction baffle 41 of the other side. At the same time, one adjusting wheel 4 is rotated counterclockwise, and the friction baffle 41 of one adjusting wheel 4 separates from the movable shaft 44. The friction baffle 41 of the other side is connected to the movable shaft 44. Finally, the user can view the advertising display screen from a distance to see if it matches the subway interior. When the display screen matches the subway interior, there is no need to continue to adjust it by adjusting the adjusting wheel 4.
