The fixing assembly 200 is used to fix the curved screen 20.

[0047] In one embodiment, please refer to Figure 4 The fixing assembly 200 includes a column 230. The column 230 is arranged on the support frame 100 along the vertical direction. The column 230 is rotatably connected to the support frame 100. The column 230 can be specifically arranged on the first support frame 130. More specifically, the column 230 can be arranged on the support beam 110.

[0056] It should be noted that if Figure 5 As shown, the installation angle is the angle formed by the installation surface 232 of the column 230 and the plane 233 where the first support frame is located. The installation angle can be Figure 5 ∠α in . When the column 230 is installed at both ends of the curved screen 20, the size of the installation angle can be half of the central angle of the curved screen 20. For example, when a flat screen is installed, the angle formed by the installation surface 232 of the column 230 and the plane 233 where the first support frame is located is 0°. That is, the installation surface 232 of the column 230 coincides with the plane 233 where the first support frame is located. When the central angle of the installed curved screen 20 is 26.88°, the angle formed by the installation surface 232 of the column 230 and the plane 233 where the first support frame is located is 13.44°. That is, the installation surface 232 of the column 230 is rotated 13.44° from the plane 233 where the first support frame is located.

[0057] Specifically, two columns 230 may be provided. Two columns 230 are provided with two mounting surfaces. The two mounting surfaces are respectively mounted at two ends of the curved screen 20. Correspondingly, four sliding members 250 may be provided. Four sliding members 250 are correspondingly arranged at two ends of the two columns 230.

[0058] In one embodiment, if Figure 4 and Figure 5 As shown, the fixing assembly 200 further includes a locking member 260. The locking member 260 is movably disposed at the end of the column 230. The locking member 260 is connected to the support frame 100 and the column 230 respectively. The locking member 260 is used to lock the rotation of the column 230.

[0059] Specifically, a strip hole 240 is formed at one end of the column 230 facing the support frame 100. The strip hole 240 is in an arc shape with a convex surface away from the curved screen 20, so that the column 230 can be adjusted to match the installation angle of the curved screen 20.

The locking member 260 is threadedly connected to the threaded hole. During the installation process, the column 230 rotates relative to the sliding member 250 and the locking member 260 through the bar hole 240 to adjust the installation angle of the mounting surface 232. When the installation angle of the mounting surface 232 is completed, the locking member 260 is rotated to fix the column 230 on the sliding member 250. The rotation or fixation of the column 230 relative to the sliding member 250 is controlled by the looseness or tightness of the locking member 260.

[0063] During operation, the column 230 rotates around the axis to adjust the installation angle of the installation surface 232. The installation angle of the installation surface 232 is adjusted according to the center angle of the curved screen 20, so that the installation surface 232 is adapted to be connected with the curved screen 20. After the installation angle of the installation surface 232 is adjusted, the locking member 260 locks the rotation of the column 230, so that the curved screen 20 is firmly fixed on the support frame 100, thereby improving the fixing effect of the curved screen 20.

The two first fixing components 210 are slidably arranged on the support beam 110 to adapt to the curved screens 20 of different lengths. When the size of the curved screen 20 is longer, the relative distance between the first fixing component 210 and the second fixing component 220 is increased. When the size of the curved screen 20 is shorter, the relative distance between the first fixing component 210 and the second fixing component 220 is reduced.

[0066] Specifically, the second fixing assembly 220 slides along the second direction. The second direction can be Figure 2 The first connecting rod 160 is arranged along the second direction.

The locking assembly 300 has a butting top. The butting top can move in a direction close to or away from the support frame 100 to butt against or release the support frame 100. When the butting top abuts against the support frame 100, the sliding member 250 is fixed to the support frame 100, and the sliding member 250 cannot slide relative to the support frame 100. When the butting top releases the support frame 100, the sliding member 250 can slide relative to the support frame 100. Specifically, the butting top abuts against the support beam 110 of the support frame 100.

[0070] In other embodiments, the locking assembly 300 may be disposed on a sliding member of the second connecting rod 170 . The locking assembly 300 can limit the second connecting rod 170 from sliding relative to the support beam 110 , thereby enhancing the reinforcement effect on the curved screen 20 .

[0071] Specifically, Figure 7 As shown, the locking assembly 300 includes a fixed seat 310, a pressing member 320, a linkage member 330 and a push member 340.

[0073] In one embodiment, the fixing device 10 also includes a bearing assembly 400. The bearing assembly 400 is disposed at the bottom of the support frame 100. The bearing assembly 400 is used to bear the curved screen 20. When the support frame 100 is moved, the bearing assembly 400 can prevent the bottom of the curved screen 20 from contacting the ground, thereby protecting the curved screen 20. At the same time, the curved screen 20 can also be moved quickly to meet the requirement that the process scene can be quickly switched. In addition, the bearing assembly 400 bears the bottom of the curved screen 20, that is, it bears a row of small screens located at the bottom of the support frame 100. When splicing multiple small screens, it can ensure that a row of small screens at the bottom of the support frame 100 are at the same height, thereby reducing the risk of poor light and dark lines on the curved screen 20.

[0074] Specifically, Figure 2 As shown, the bearing assembly 400 includes a first bearing member 410, a second bearing member 420 and a third bearing member 430. In one embodiment, two second fixing assemblies 220 are provided. The bottom of one of the second fixing assemblies 220 is disposed between the first bearing member 410 and the second bearing member 420. The bottom of the other second fixing assembly 220 is disposed between the second bearing member 420 and the third bearing member 430.

[0075] It should be noted that the steps of splicing the entire curved screen 20 are specifically as follows:

[0076] The casters 180 at the bottom of the support frame 100 are locked so that the entire support frame 100 is in a fixed state.

[0077] Slide one of the first fixing components 210 to the left side of the support frame 100, such as Figure 1 The column 230 of the first fixing assembly 210 is rotated to adjust the installation angle of the installation surface 232 of the column 230 to half of the central angle of the curved screen 20 .

[0079] The small screen body is placed vertically on the bearing assembly 400 , and the left connecting piece of the small screen body is fixed on the mounting surface 232 of the column 230 .

[0080] Connect multiple small screens in sequence according to the preset curvature requirements to complete the installation of the first row of small screens.

[0081] Slide another first fixing component 210 to the right side of the support frame 100 , and rotate the column 230 of the right first fixing component 210 , so that the connecting piece of the rightmost small screen is fixed on the column 230 of the right first fixing component 210 .

[0082] The rotation of the right first fixing assembly 210 is locked by the locking member 260. The sliding of the right first fixing assembly 210 is locked by the locking assembly 300.

[0083] The second fixing assembly 220 is driven to slide relative to the first connecting rod 160, so that the second fixing assembly 220 is connected to the connecting pieces on both sides of the middle small screen body. The rotation of the second fixing assembly 220 is locked by the locking member 260. The sliding of the second fixing assembly 220 relative to the first connecting rod 160 is locked by the locking assembly 300.

[0084] After the small screens in the first row are fixed, the small screens in the second row are spliced ​​from left to right in sequence to complete the splicing of the small screens in the second row.

[0085] Repeat the splicing steps of the second row, splicing upwards row by row, to complete the splicing and fixing of the entire curved screen 20.
