Subsequently, the fixed tray bore 313 on the fixed disk 310 and the bracket bore 112 on the bracket 110 are aligned and fixed using four sets of bolts, and the fixed disk 310 cannot be rotated. Finally, the entire top cover 200 is buckled from the top to the bottom, and the U-shaped top groove 210 on the inner wall of the left and right sides of the top cover 200 and the U-shaped bottom groove 111 on the bracket 110 are correspondingly fixed to ensure the rotation shaft 300. Will not move up. In addition, the limiting component 314 disposed on the rotating shaft 300 isolates the bracket 110 from the fixed disk 310, and effectively prevents the axial movement of the fixed disk 310 on the rotating shaft 300 under the limit of the limiting component 314. Further, friction between the fixed disk 310 and the bracket 110 is prevented.

[0029] The above is the completion of the fixing process of the flexible screen, which can be used for standing or transporting. Since the flexible screen is tightened under the tension of the elastic member, it is wound around the outer side of the rotating shaft according to the spiral A. Therefore, during transportation, the screen can be shocked by the elastic member, and the design of the spiral A can be Make sure there are no collisions and friction between adjacent screens to ensure the safety of the screen. At the same time, the fixed disc boring and the bracket boring are aligned and fixed to ensure that the flexible screen is not freely rotated after being fixed to the fixing component, and the top cover also ensures that the flexible screen fixed inside is sealed during transportation. Status, get effective protection.

[0030]
