[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. On the construction site, rotate the support base to form an angle with the base. The locking rod on the convex plate is engaged in the locking hole on the rotating rod under the action of the spring tension, which fixes the support base and forms a stable vertical support structure with the base.

[0031] Place a display module on the horizontal bar of column three, insert the L-shaped plug into the insertion slot, and tighten the tensioning bolt to securely install the display module onto the horizontal bar.

[0055] likeFigure 3 As shown, a through groove is provided on the first column 3, and a rack 17 is provided on the second column 11. The rack 17 cooperates with the gear 14. The rack 17 is located in the through groove. There are two racks 17, and an opening is provided between the two racks 17.

[0056] The column 3 10 is provided with a rack 2 18 in the middle, and the rack 2 18 is inserted into the opening between the two racks 17.

[0057] Mounting holes are provided on each of the three columns: column 1 (3), column 2 (11), and column 3 (10). A horizontal plate 4 is fixedly installed on each of the three columns: column 1 (3), column 2 (11), and column 3 (10). An arc-shaped connecting plate is provided on the horizontal plate 4. The arc-shaped connecting plate is sleeved on the outer wall of column 1 (3). Each arc-shaped plate is welded to column 1 (3), column 2 (11), and column 3 (10).

[0058] Each of the horizontal plates 4 is provided with a mounting component for mounting a display screen. There are two mounting components, each including a plug sleeve 9 and a tension bolt 6. The horizontal plate 4 is provided with two through holes. The plug sleeve 9 is slidably installed at the through holes. One end of the tension bolt 6 is rotatably connected to the horizontal plate 4, and the other end of the tension bolt 6 is threadedly connected to the plug sleeve 9.

[0059] like Figure 7 As shown, each LED display screen has a mounting bracket 31 fixedly installed on its back. The mounting bracket 31 is fixedly installed to the display module by screws, so that the mounting bracket 31 and the display module are integrated. The back of the mounting bracket 31 is provided with an L-shaped plug 28, which is used to insert into the plug sleeve 9.

[0060] Rotate the tensioning bolt 6 to move the plug sleeve 9 into the horizontal plate 4, causing the plug block to move in the direction of the horizontal plate 4. The plug sleeve 9 then fixes the plug block, completing the initial installation of the display module.

[0061] Each mounting bracket 31 has a connector 33 at its bottom and a connector 35 at its top. The connector 33 and the connector 35 are connected to form a vertical parallel connection line. A main power cord is also provided and connected to the connector 33.

[0062] Each mounting bracket 31 is also provided with a signal plug 36 at its bottom and a signal interface 34 at its bottom. The signal plug 36 and the signal interface 34 form a vertical series circuit and a main signal wire is provided to connect to the signal plug 36.

[0063] The mounting bracket 31 internally houses a power board 38, a signal board 37, a processor, etc., and each power board 38, interface, and connector 33 are configured as follows: Figure 10 The parallel circuit connection shown forms a connection between each of the signal boards 37, signal plugs 36, and signal interfaces 34 as follows: Figure 9 The series circuit connection is shown.

[0064] When assembling the second-layer mounting bracket, when aligning the L-shaped plug 28 with the plug sleeve, the plug 33 is also aligned with the plug interface 35, and at the same time, the signal interface 34 is also aligned with the signal plug 36. When the L-shaped plug 28 is inserted into the plug sleeve 9, the plug 33 and the signal plug 36 are also inserted into the plug interface and the signal interface 34 respectively, completing the vertical power wiring connection and signal line connection.

[0065] like Figure 3 As shown, a second load-bearing rod 19 is slidably installed on the first load-bearing rod 7, and a third load-bearing rod 12 is slidably installed on the second load-bearing rod 19. Each load-bearing rod 7, the second load-bearing rod 19, and the third load-bearing rod 12 is provided with a rotating rod 8. A horizontal bar 20 is fixedly connected to the top of each column 1 3, column 2 11, and column 3 10. Each horizontal bar 20 corresponds to each rotating rod 8. The connecting assembly includes a convex plate 23 and a connecting shaft 24. Two convex plates 23 are fixedly connected to the horizontal bar 20. The rotating shaft 15 is fixedly installed on the two convex plates 23. The rotating rod 8 is rotatably connected to the connecting shaft 24. The convex plates 23 are arranged vertically, and each convex plate 23 has an insertion hole, on which the connecting shaft 24 is provided.

[0066] Both the first load-bearing rod 7 and the second load-bearing rod 19 have threaded holes 21 on their side walls. A threaded clamp 22 is installed inside the threaded hole 21. The second load-bearing rod 19 and the third load-bearing rod 12 are fixed by applying pressure through rotating the threaded clamp 22.

[0067] The convex plate 23 has a locking hole 16, the locking hole 16 has a locking rod 27, the locking rod 27 has a spring, and the end of the rotating rod 8 has a locking hole 16 that cooperates with the locking rod 27.

[0068] Based on the above equipment structure, the specific operating steps of this application are as follows:

[0069] Step 1: Set up the LED display screen

[0070] When the support seat 2 is rotated at the site, it forms a 90-degree angle with the base 1. The locking rod 27 on the protruding plate 23 is engaged in the locking hole 16 on the rotating rod 8 under the action of the spring tension, which forms a fixed limit on the support seat 2. The support seat 2 and the base 1 form a stable vertical support structure.

[0071] Place a display module on the horizontal bar 20 of the third column 10, insert the L-shaped plug 28 into the insertion slot, and tighten the tensioning bolt 6 to securely install the display module onto the horizontal bar 20. Rotate the rocker wheel 13 located on the second column 11, which will drive the rotating shaft 15 to rotate, thereby causing the gear 14 to rotate and push the rack 2 18 upward to move the third column 10 upward to the top of the second column 11. This completes the installation of the third layer LED display module.

[0072] Place the second layer LED display module on the horizontal bar 20 on column 21, and insert the L-shaped plug 28 into the insertion slot. Rotate the tension bolt 6 to complete the installation of the second layer LED display module. Rotate the rocker wheel 13 on column 21 to make the gear 14 push column 21 upward. When column 21 is moved to the top of column 3, place the first layer LED display module on the horizontal bar 20 on column 3, and use the tension bolt 6 on the hanging assembly to lock and fix the L-shaped plug 28 to complete the fixation of the first layer LED display module. The above steps complete the stacking and installation of the three layers of LED display modules.

[0073] Step Two

[0074] like Figure 9 As shown, step one is to complete the overall structure of one unit. The entire LED display screen requires multiple units to be arranged and assembled. After completing the assembly in step one, the multiple units are aligned and spliced ​​sideways. A positioning groove is provided on one side of the base 1, and a positioning protrusion is provided on the side of the base 1 opposite to the positioning groove. Align the positioning block on the base 1 of one unit with the positioning groove on the base 1 of another unit, insert the positioning protrusion into the positioning groove, and align the planes of the two bases. Use the alignment bolt 30 to connect with the positioning screw hole on the fixing seat 32, and screw the alignment bolt into the positioning screw hole to complete the side connection and installation of the display screen module.

[0075] Step 3

[0076] After each display screen body is placed and each layer of display screen bodies is raised to the specified height, the power bus 40 is inserted into the interface of the first layer mounting bracket 31 to form a parallel circuit connection between the multiple rows of display screen bodies. The signal bus 39 is connected to each signal interface 34 on the first layer mounting bracket 31, and the signal bus is connected to the signal source to complete the overall construction steps. It is not necessary to use multiple signal cables to connect one by one between each mounting bracket 31, making the wiring connection more convenient.

[0077] Step Four

[0078] After use, the entire device needs to be stored away. First, loosen the tension bolt 6 at the back of the first layer display module, remove the first layer display module, then rotate the rocker wheel 13 on the first column 3 to move the second column 11 downwards, and then remove the second layer display module.

[0079] It is worth noting that each LED display screen has a data cable interface on the back for transmitting images, and the data cables are all of sufficient length. The technical solution structure of this application does not affect the routing and connection of the data cables and wires.

[0080] Repeat this process to remove the third-layer display module. After removing the display module, pull up the locking rod 27 to remove the limiting fixation on the support base 2. Rotate and fold the support base 2 and the base 1 to reduce the space occupied by the connection structure between the support base 2 and the base 1, making it easier to store and transport.

[0081] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
