[0057] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0058] like Figure 1-Figure 13As shown, the modular movable display device includes a unit module 1 and a rotating module 3. A plurality of unit modules 1 are connected in sequence to form an intermediate module. Both sides of the intermediate module are rotatably connected with the rotating modules 3. The unit module 1 and the rotating module 3 include a hollow base 2. A display module 11 is fixed to the top of the base 2. A square tube 22 is fixed between the inner walls of the bottom of the base 2. A plurality of threaded feet 5 are arranged below the base 2. The threaded rods 52 of the threaded feet 5 pass upward through the square tube 22. A rolling assembly 6 is fixed downward on the front wall of the square tube 22. A connecting and fixing fixture 8 is fixed to the top of the square tube 22. Two adjacent bases 2 in the intermediate module are fixed by the connecting and fixing fixture 8.

[0059] The bottom brackets of the middle module are fixed by connecting and fixing fixtures 8, and the rotating module 3 and the bottom bracket 2 of the unit module 1 are connected by fixing angle devices 7, so the fixing and disassembly are very convenient and the assembly efficiency is high.

[0060] The bases of the middle modules are fixed by connecting and fixing fixtures 8. In actual use, the number of unit modules 1 can be selected according to the needs of the actual site, so that the display device is flexibly applicable to different use sites.

[0061] Attached frames 21 are fixed upward on both sides of the base 2 , and the display module 11 is threadedly connected between the two attached frames 21 .

[0062] The cooperation between the base 2 and the auxiliary frame 21 fixes the display module 11 from the bottom and both sides to prevent the display module 11 from shaking; but at the same time, a threaded connection is used instead of fixing, which facilitates the installation and removal of the display module and is suitable for different display modules 11.

[0063] The display module 11 includes a fixed frame, in which a light-emitting component is fixed. A plurality of controllers are arranged in the frame of the fixed frame. The controllers are connected by a transmission line, and one end of the transmission line extends from the bottom of the fixed frame into the base 2.

[0064] The controllers of the unit module 1 and the rotating module 3 are integrated inside the fixed frame. Finally, only a network cable and a power cable extend from the bottom to connect the module with the overall control system. The other parts are closed.

[0065] During assembly, the light-emitting component is fixed in the fixing frame, and the two sides of the fixing frame are fixed to the auxiliary frame 21 by bolts. The transmission line extending from the bottom of the fixing frame enters the bottom bracket 2 through the through hole at the top of the bottom bracket 2.

[0066] The luminous components are various display products with transparent characteristics, including but not limited to luminous glass, transparent display glass, transparent plastic board type LED display products, and transparent grille type LED display products.

[0067] If you are using hard luminous products such as luminous glass, transparent display glass, etc., directly fix the product to the fixing frame; if you are using other transparent soft luminous products, you need to fix the product to glass or other hard substrates, and then fix the hard substrate to the fixing frame.

[0068] The connecting and fixing fixture 8 includes a fixing seat 83 and a handle 82 fixed at one end of the square tube 22. Two connecting rods 821 are fixed at intervals at the front end of the handle 82. The top of the fixing seat 83 is located between the two connecting rods 821. The two connecting rods 821 are rotatably connected to the top of the fixing seat 83 through a first shaft 84. A second shaft 85 is also rotatably connected between the two connecting rods 821. A hook 81 is fixed to the front end of the second shaft 85. A fixing block 9 that cooperates with the hook 81 is fixed to the inner side wall of the base 2. The fixing block 9 is located above the other end of the square tube 22.

[0069] When fixing is required, the handle 82 is rotated in the direction of the hook 81 with the first axis 84 as the axis. At this time, the second axis 85 between the two connecting rods 821 will drive the hook 81 to move forward until the fixed block 9 to be hooked is within the range that the hook 81 can hook. Then the handle 82 is rotated away from the hook 81, thereby driving the hook 81 to move backward until it hooks the fixed block 9. At this time, the two adjacent base brackets 2 are fixed by connecting the fixing clamps.

[0070] When disassembly is required, the handle 82 is rotated toward the hook 81 to drive the hook 81 to move forward and separate from the fixing block 9, thereby realizing disassembly between the two bottom brackets 2.

[0071] The bottom brackets 2 of the middle module are fixed by connecting and fixing fixtures 8. When fixing is required, the bottom bracket 2 can be hooked with the fixing block 9 on the inner wall of the adjacent bottom bracket 2 through the hook 81 at the bottom thereof, so that the bottom bracket 2 is fixed to the adjacent bottom bracket 2, and then the hook 81 at the bottom of the adjacent bottom bracket 2 is hooked with the fixing block 9 of another bottom bracket 2, and multiple bottom brackets 2 are fixed in turn by connecting and fixing fixtures 8. When fixing is not required, the handle 82 is turned to drive the hook 81 at its front end to separate from the fixing block, so as to realize the disassembly between adjacent bottom brackets.

[0072] By the rotation connection between the handle 82 and the first shaft 84, the handle 82 can be flexibly rotated, so that the fixing operation of the connecting fixing clamp 8 is very flexible and does not require a lot of time and energy; the second shaft 85 drives the rotation of the hook 81, so that the operator can flexibly adjust the position of the hook 81 according to the position of the fixing block 9 until the hook 81 hooks the fixing block 9, so that the hook 81 and the fixing block 9 are very firmly matched and the fixing effect is good.

[0073] The fixing block 9 is arranged in the hook of the hook 81, and this fixing mode is very firm, so that the fixing between two adjacent bottom brackets 2 is very firm, and the fixing effect is very good. Simultaneously, this fixing mode is easy to disassemble and install, and is very convenient in actual operation.

[0074] A ground anchor base 51 is fixed to the bottom of the threaded rod 52, and a first nut 55, a second nut 54, and a third nut 53 are threadedly connected to the outer wall of the threaded rod 52 from top to bottom in sequence. The square tube 22 is located between the first nut 55 and the second nut 54, and the square tube 22 is bolted to the first nut 55 and the second nut 54. The third nut 53 is located above the ground anchor base 51.

[0075] The square tube 22 is located between the first nut 55 and the second nut 54, and the first nut 55 and the second nut 54 clamp the square tube 22 from the top and the bottom respectively, so that the square tube 22 is still in a clamped state during the up and down movement, ensuring that the square tube 22 will not tilt or deviate during the up and down movement, thereby ensuring that the base 2 fixed to the square tube 22 and the display module 11 on the top of the base 2 will not deviate or tilt when moving with the square tube 22, and the stability and safety are very high.

[0076] The rolling assembly 6 includes a connecting block 64, a top of which is fixed with an iron plate 221, the iron plate 221 is fixed to the front wall of the square tube 22, and a groove 63 for accommodating the roller 61 is opened upward at the bottom of the connecting block 64, and the roller 61 is rotatably connected to the inner wall of the groove 63 through a rotating shaft 62.

[0077] The use of the threaded feet 5 and the rollers 61 can not only ensure the stability of the display device during use and assembly, but also enable it to be flexibly moved to adjust its position, and the flexibility is very high.

[0078] By rotating the threaded foot 5, the height of each base 2 can be adjusted according to the flatness of the site, so that the top surfaces of all bases 2 are located on the same horizontal plane, so that all display modules can be located on the same horizontal plane. Therefore, the display device is also suitable for sites with uneven ground planes, and has a very wide range of applications.

[0079] When the display device stays at a specified position, the threaded anchor 5 contacts the ground and plays a role in supporting the entire display device. When the display device needs to move, the threaded anchor 5 is rotated so that the threaded anchor 5 drives the square tube 22, the rolling assembly 6, the bottom bracket 2, and the display module 11 to move downward at the same time until the roller 61 of the rolling assembly 6 contacts the ground, and the rolling of the roller 61 drives the unit module 1 and the rotating module 3 to move to the specified position. Then the threaded anchor 5 is rotated so that the threaded anchor 5 drives the rolling assembly 6 to move upward until the roller 61 leaves the ground and the anchor base 51 contacts the ground again.

[0080] The rotating module 3 is rotationally connected to the adjacent unit module 1 via a fixed angler 7, and the fixed angler 7 includes a first fixed plate 71 and a second fixed plate 73 rotationally connected via a rotating shaft 72, the upper portion of the first fixed plate 71 is fixed to the auxiliary frame 21 of the rotating module 3, the lower portion of the first fixed plate 71 is fixed to the base 2 of the rotating module 3, the upper portion of the second fixed plate 73 is fixed to the auxiliary frame 21 adjacent to the rotating module 3, and the lower portion of the second fixed plate 73 is fixed to the base 2 adjacent to the rotating module 3.

[0081] The unit module 1 and the rotating module 3 are rotatably connected via the angle fixing device 7. The first fixing plate 71 and the second fixing plate 73 of the angle fixing device 7 play the role of fixing the base 2, and the rotating shaft 72 plays the role of flexibly rotating to adjust the angle between the first fixing plate 71 and the second fixing plate 73. The rotating module 3 can be rotated as needed to adjust the angle between the rotating module 3 and the adjacent unit module 1, thereby increasing the viewing angle of the display device and the stability when standing.

[0082] The base of the rotating module 3 is a trapezoidal hollow frame, the base of the unit module 1 rotatably connected to the rotating module 3 is a trapezoidal frame that matches the trapezoidal hollow frame, and the bases of the other unit modules not connected to the rotating module are square hollow frames. A plurality of bases 2 are sequentially connected to form an internally connected cavity.

[0083] The trapezoidal hollow frame of the rotating module 3 cooperates with the trapezoidal frame of the adjacent unit module 1 , so that the rotating module 3 and the adjacent unit module 1 cooperate more closely, which not only ensures the stability of the display device when in use, but also facilitates the rotation of the rotating module 3 .

[0084] The cavity formed inside facilitates various transmission lines to pass through the base and connect to the power supply and the overall control system, which is both beautiful and convenient.

[0085] The top, front and rear of the base 2 of the unit module 1 are provided with protective buckle covers 4, and the positions of the rotating module 3 that are not in contact with the unit module 1 are provided with protective covers 4. The top of the protective cover 4 is provided with a hand buckle 41, and the protective cover 4 is opened and closed by pulling the hand buckle 41.

[0086] The flexible opening protection cover 4 is convenient for opening the protection cover 4 at any time during the actual operation to perform adjustment or maintenance, and has strong operability.

[0087] The assembly method of the modular movable display device comprises the following steps:

[0088] S1: forming a module: fixing the light-emitting component in the fixing frame, fixing the two sides of the fixing frame to the auxiliary frame 21 by bolts, and the transmission line extending from the bottom of the fixing frame enters the bottom bracket 2 through the through hole at the top of the bottom bracket 2;

[0092] S5: Adjust the position: rotate the threaded foot 5, so that the threaded foot 5 drives the square tube 22, the rolling assembly 6, the bottom bracket 2, and the display module 11 to move downward at the same time, until the roller 61 of the rolling assembly 6 touches the ground, and the rolling of the roller 61 drives the unit module 1 and the rotating module 3 to move to the specified position;

[0093] The threaded foot 5 is rotated so that the threaded foot 5 drives the rolling assembly 6 to move upward until the roller 61 leaves the ground and the foot base 51 contacts the ground;

[0094] S6: Adjusting the levelness: rotating one or more threaded feet 5 as needed to match the levelness of adjacent unit modules 1 and / or rotating modules 3;

[0095] S7: Internal integrated assembly: The transmission lines extending from the bottom of the unit module 1 and the rotating module 3 are centrally connected from the inside of the base 2 to the middle to the power supply and the overall control system, and only one power line is reserved at the bottom of the middle base 2 to the outside.

[0096] The operating temperature of the light emitting component is -30°C-70°C.

[0097] The base bracket 2 in the middle position is provided with a power supply and a general control system, and the transmission lines between the modules are connected to the power supply and the general control system from the inside of the base bracket to the middle. Only one power line is reserved from the bottom of one base bracket 2 to the outside. When in use, it is only necessary to connect the reserved power line to the corresponding cable provided on site.
