DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 4 As shown, this embodiment provides a mobile opening and closing screen, including:

[0027] A fixed plate 1 is arranged at the top, and an annular slide rail 3 is fixedly connected to the outer bottom surface of the fixed plate 1 through a plurality of first fixed columns 2; a plurality of sliding components are slidably connected to the annular slide rail 3, a mounting block 4 is fixedly connected to the bottom of the sliding component, and a display screen 5 is fixedly connected to the bottom of the mounting block 4;

[0028] The rack rail 6 is equidistantly arranged inside the annular slide rail 3. The top of the rack rail 6 is fixed to the fixed plate 1 through a plurality of second fixing columns 7. The outer side of the rack rail 6 is meshedly connected with a driving assembly, and the driving assembly is fixed to the sliding assembly.

[0029] The fixed plate 1 is fixed on the roof of the exhibition hall. Several display screens 5 are provided as needed, and all slide along the annular slide rail 3 through a sliding assembly. The annular slide rail 3 increases the display angle and range of the display screen 5, so that visitors can view the display screen 5 from all directions; each display screen 5 is separately configured with a driving assembly, and the driving assembly is engaged and transmitted along the gear rail 6 to push the mounting block 4 and the sliding assembly fixed to the mounting block 4 to slide along the annular slide rail 3, giving the display screen 5 sliding power; each driving assembly can be individually controlled by the control center to drive each display screen 5 individually, and the driving assembly can be driven in two directions, front and back, so that the display screens 5 can be moved closer or farther from each other, forming the opening and closing of the display screens 5; the multiple display screens 5 combined can interact to jointly display a larger picture. The present application enriches the display method of the display screen 5 on the annular slide rail 3, expands the display angle and range of the display screen 5, and has a better exhibition effect.

[0030] A further optimized solution is that the sliding assembly includes three sliding columns 8, the three sliding columns 8 are isosceles triangles, two of which are slidably connected to the outer side of the annular slide rail 3, and one is slidably connected to the inner side of the annular slide rail 3; the three sliding columns 8 are centrally rotatably connected to a rotating shaft 9, and the bottom of the three rotating shafts 9 extend out of the sliding columns 8 and are fixedly connected to the mounting block 4.

[0031] The three sliding columns 8 are slidably connected to the annular slide rail 3 from both inside and outside, and a sliding column 8 is provided on the inner side to facilitate the angle adjustment at the arc track of the annular slide rail 3; to realize the movement of the display along the arc track, the three sliding columns 8 are fixedly connected to the mounting block 4 through the rotating shaft 9, driving the display screen 5 fixed to the mounting block 4 to move along the annular slide rail 3.

[0032] According to a further optimized solution, an annular groove 10 is provided at the center of the sliding column 8 , and convex strips 11 are protruded from both sides of the annular slide rail 3 , and the convex strips 11 are provided corresponding to the groove.

[0033] The grooves of the sliding column 8 are stuck in the convex strips 11 on both sides of the slide rail, limiting the position of the sliding column 8 to prevent the sliding column 8 from falling off the slide rail, and at the same time giving the sliding column 8 an upward force to lift the bottom display screen 5.

[0034] A further optimized solution is that the drive assembly includes a motor 12, the output end of the motor 12 is transmission-connected with a gear 13, the gear 13 is meshingly connected with the outer side of the rack 6, a gear shaft 14 is fixedly connected to the center of the gear 13, a connecting plate 15 is fixedly connected to the bottom of the gear shaft 14, and the connecting plate 15 is fixedly connected to the mounting block 4.

[0035] The motor 12 drives the gear 13 to rotate, so that the gear 13 moves along the rack 6. The movement of the gear 13 drives the gear shaft 14 and the connecting plate 15 to move, and then drives the mounting block 4 and the display screen 5 to move. Because the rack 6 and the annular slide rail 3 are equidistantly arranged, the movement of the gear 13 can perfectly drive the sliding assembly to move along the annular slide rail 3 without any jamming.

[0036] Furthermore, the motor 12 is fixed to the connecting plate 15 via a bracket, which is not shown in the figure.

[0037] A further optimized solution is that a limiting rail 16 is correspondingly arranged below the annular slide rail 3 , a bottom T-slot 17 is opened at the center of the limiting rail 16 , and a limiting wheel 18 is rotatably connected to the bottom center of the display screen 5 , and the limiting wheel 18 is slidably connected to the bottom T-slot 17 .

[0038] The limiting rail 16 is embedded in the floor of the exhibition hall or under other fixed tables, and the limiting wheel 18 slides in the T-slot following the movement of the display screen 5 to limit the position of the lower end of the display screen 5 to prevent the lower end of the display screen 5 from tilting and shaking.

[0039] To further optimize the solution, a plurality of first suspension rods 19 are fixedly connected to both sides of the top surface of the mounting block 4, and the distance from the axis of the first suspension rod 19 to the center of the annular slide rail 3 is equal to the distance from the axis of the rotating shaft 9 to the center of the annular slide rail 3; a first pulley 20 is rotatably connected to the top of the first suspension rod 19, and a first T-slot 21 is opened on the fixed plate 1 corresponding to the moving track of the first pulley 20, and the first pulley 20 is slidably connected in the first T-slot 21.

[0040] The first suspension rod 19 and the first pulley 20 hang the mounting block 4 on the fixed plate 1, thereby increasing the stability of the mounting block 4 and reducing the force on the sliding column 8, making the sliding of the sliding column 8 easier; when the distance from the axis of the first suspension rod 19 to the center of the annular slide rail 3 is equal to the distance from the axis of the rotating shaft 9 to the center of the annular slide rail 3, the moving trajectory of the first suspension rod 19 is the same, and a first T-slot 21 can be shared, thereby reducing the number of slots to be opened.

[0041] According to a further optimization scheme, there are three first suspension rods 19 in the form of an isosceles triangle, which are symmetrically arranged along the annular slide rail 3 , two of which are arranged on the inner side of the annular slide rail 3 , and one is arranged on the outer side of the annular slide rail 3 .

[0042] The first suspension rod 19 and the first pulley 20 are symmetrically arranged along the annular slide rail 3 to balance the force on the mounting block 4 and make the mounting block 4 more stable.

[0043] To further optimize the solution, a plurality of second hangers 22 are provided on both sides of the connecting plate 15, and the distances between the plurality of second hangers 22 and the rack rail 6 are equal. A second pulley 23 is fixedly connected to the top of the second hanger 22, and a second T-slot 24 is provided on the fixed plate 1 corresponding to the moving track of the second pulley 23, and the second pulley 23 is slidably connected in the second T-slot 24.

[0044] The second suspension rod 22 and the second pulley 23 are similar in structure and function to the first suspension rod 19 and the first pulley 20 , but the second suspension rod 22 and the second pulley 23 are used to lift the connecting plate 15 , thereby lifting and fixing the driving assembly to the fixing plate 1 .
