[0001] The present invention relates to the technical field of display screens, and in particular to a special-shaped cylindrical screen and a mounting and fixing structure thereof. Background Art

[0002] A cylindrical screen is a screen with a special shape. It is in the shape of a cylinder and is usually used in display devices. This screen shape can provide users with a wider field of view. It is particularly suitable for virtual reality and augmented reality devices, as well as certain special display application scenarios. The cylindrical screen can provide a more immersive visual experience and has certain advantages in specific application fields.

[0003] Due to the particularity of cylindrical screens, many users will use multiple cylindrical screens in combination. However, at present, when installing cylindrical screens, their installation components are mostly in-line or matrix. Therefore, it is inconvenient to install them at some installation points with curved surfaces, especially when installing them on the outside of some buildings or on columns.

When the screw rotates, it will have a threaded connection with the mounting frame. Therefore, the screw will rise and fall, thereby driving the connecting plate to rise and fall, thereby driving the conductive block to descend, and completing the position limiting of the special-shaped cylindrical screen. After that, start the drive motor, and the drive motor can drive the drive wheel to rotate, and the drive belt can provide rotational power for the rotating shaft. Because the outer side of the rotating shaft is provided with a connecting wheel, the transmission effect between the connecting belts can make the connecting wheels rotate simultaneously, and then multiple rotating shafts can rotate simultaneously, so that the special-shaped cylindrical screen can be displayed in rotation.

[0065] Working principle:

Because of the relationship between the flat key 10 and the keyway 9, the screw rod 6 will rotate with the rotating sleeve 8, and the screw rod 6 will be threadedly connected with the mounting frame 1 when rotating. Therefore, the screw rod 6 will be lifted and lowered, thereby driving the connecting plate 4 to be lifted and lowered, thereby driving the conductive block 5 to descend, and completing the limitation of the special-shaped cylindrical screen 2. After that, the driving motor 17 is started, and the driving motor 17 can drive the driving wheel 18 to rotate, and the driving belt 20 can provide rotational power for the rotating shaft 13. Because the outer side of the rotating shaft 13 is provided with a connecting wheel 14, the transmission effect between the connecting belts 15 can make the connecting wheels 14 can be synchronized. When rotating, multiple rotating shafts 13 can be rotated at the same time, so that the special-shaped cylindrical screen 2 can be rotated for display. Finally, the fixing box 23 on one side of a mounting frame 1 is inserted between the two connecting ears 21 on the other side of the mounting frame 1, and the adjusting knob 21 is used to drive the adjusting shaft 30 to rotate. The adjusting shaft 30 will drive the gear 31 to rotate during the rotation process.

The movable plate 28 will drive the limiting column 29 to move during the movement. The limiting column 29 will cooperate with the connecting hole 22 during the movement, so that the fixing box 23 can be installed between the two mounting blocks 24. Multiple mounting frames 1 are connected in sequence in this way, so that the device can be installed on a curved surface.
