The flexible screen 400 is fixed on the base 100 through a fixing component, the top cover 200 covers the base 100, and the support 110 is arranged on the base 100. FIG. 2 is a schematic view of a fixing assembly according to the present invention. As shown in fig. 1 and fig. 2, the fixing assembly includes a rotating shaft 300, two fixing discs 310 are respectively disposed at two ends of the rotating shaft 300, and a plurality of fixing members for fixing the flexible screen are correspondingly disposed on opposite surfaces of the fixing discs 310; the rotation shaft 300 is mounted on the bracket 110. In order to enhance the rigidity of the fixed disk, a flange 320 is further disposed on the inner side of the fixed disk 310, and the fixed disk and the flange are tightly fixed at two ends of the rotating shaft 300. In practical applications, the fixing plate 310 may be fixed to the flanges 320 at the left and right ends of the rotation shaft 300 by fastening screws. In order to ensure that the flexible screen does not generate friction after being fixed, a plurality of fixing members are correspondingly arranged on the opposite surfaces of the two fixed disks 310 in a way that the spiral line A gradually opens.

Fig. 3 is a schematic structural view of the fixing component of the present invention fixed on the base. As shown in fig. 3, in order to keep the flexible screen under tension while being firmly positioned, the fixing member includes a sheep eye screw 311 and an elastic element 312, and in the embodiment shown in fig. 3, the elastic element 312 is a spring, but of course, a person skilled in the art may make other specific selections according to actual needs. The sheep-eye screw 311 is fixed on the fixed plate 310, a screen opening 410 is formed in the side edge of the flexible screen 400, and hooks on two sides of the elastic element 312 are connected between the sheep-eye portion of the sheep-eye screw 311 and the screen opening 410 respectively. Since a plurality of sheep eye screws are arranged on the inner side surface of the fixed disk 310 in a gradually-opened manner according to the spiral line a, and the sheep eye screws 311 on the fixed disks 310 on the left and right sides are aligned, the elastic elements 312 with hooks at both ends are used to fix the sheep eye positions of the screen opening 410 and the sheep eye screws 311. The flexible screen 400 is tightened by the tensile force of the elastic element 312 and is wound on the outer side of the rotating shaft 300 in a way that the spiral line a gradually opens.

Referring to fig. 1, in order to ensure that the fixing assembly can be stably positioned between the base 100 and the top cover 200 during transportation, a U-shaped bottom groove 111 is formed at the top end of the bracket 110, and two ends of the rotating shaft 300 are respectively erected on the U-shaped bottom groove 111. The inner walls of the two sides of the top cover 200 are correspondingly provided with U-shaped top grooves 210; when the top cover 200 covers the base 100, the U-shaped bottom groove 111 and the U-shaped top groove 210 are correspondingly engaged to radially clamp and fix the two ends of the rotating shaft 300, so as to prevent the rotating shaft 300 from moving upwards.

Further, as shown in fig. 2, the bracket 110 has a bracket opening 112, and the fixing plate 310 has a fixing plate opening 313. After the flexible screen 400 is completely fixed on the fixing assembly, the bracket openings 112 and the fixing plate openings 313 are aligned and fixed to each other by inserting the positioning bolts 113, and the bracket openings 112 and the fixing plate openings 313 are provided in corresponding sets. The positioning bolt 113 may be a bolt, a screw or a stud, as required. Specifically, in the embodiment shown in fig. 3, after the flexible screen 400 is fixed to the fixing member, the fixing plate opening 313 and the bracket opening 112 may be aligned and fixed using four sets of bolts, and the fixing plate 310 may not be rotated.

Fig. 4 is a schematic structural view of the limiting element of the present invention. As shown in fig. 4, in order to prevent the fixed disk 310 from moving axially on the rotating shaft 300 and further avoid friction between the fixed disk 310 and the bracket 110, two ends of the rotating shaft 300 are respectively provided with a limiting member 314, and each limiting member 314 is respectively arranged at an inner side of the bracket 110 and an outer side of the fixed disk 310.

As shown in fig. 1 to 4, the fixing process of the present invention is as follows:

the rotating shaft 300 is placed on the bracket 110, so that both ends of the rotating shaft 300 are respectively embedded on the U-shaped bottom groove 111 of the bracket. Firstly, winding a section of flexible screen 400, and connecting an elastic element 312 with hooks at two ends with a screen opening 410 and a sheep eye screw 311; then the rotating shaft 300 is rotated again, and the newly wound part is connected with the screen opening 410 and the sheep eye screw 311 by the elastic element 312 with the hook; the rotating shaft 300 is rotated and fixed in this way until all the flexible screens 400 are completely fixed, so that the flexible screens 400 are tightened under the action of the tensile force of the elastic elements 312 and wound on the outer side of the rotating shaft 300 layer by layer in a way that the spiral line A gradually opens. Subsequently, the fixed plate opening 313 of the fixed plate 310 and the bracket opening 112 of the bracket 110 are aligned and fixed using four sets of bolts, and the fixed plate 310 cannot rotate. Finally, the whole top cover 200 is buckled from top to bottom, and the U-shaped top grooves 210 on the inner walls of the left side and the right side of the top cover 200 are correspondingly matched and fixed with the U-shaped bottom grooves 111 on the bracket 110, so that the rotating shaft 300 is ensured not to move upwards. In addition, the limiting element 314 arranged on the rotating shaft 300 separates the bracket 110 and the fixed disk 310, and under the limiting action of the limiting element 314, the fixed disk 310 is effectively prevented from moving axially on the rotating shaft 300, so that friction between the fixed disk 310 and the bracket 110 is avoided.

The fixing process of the flexible screen is completed, and the flexible screen can be used for standing or transportation. Because flexible screen is tightened under elastic element's pulling force effect, twines in the pivot outside according to helix A mode of gradually opening, consequently, in the transportation, the screen can the shock attenuation under elastic element's effect, and helix A's design can ensure can not bump and rub between the adjacent screen to ensure the safety of screen. Simultaneously, fixed disk trompil and support trompil align and fix to can not produce the free rotation after guaranteeing that the flexible screen is fixed on fixed subassembly, the top cap has also guaranteed to make the flexible screen of fixing inside in the transportation be in airtight state, obtains effective protection.
