[0024] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0025] For example, Figure 1 And 2As shown, the embodiment provides an ultra-thin double-sided display screen, which comprises a support frame and a plurality of display modules 1 arranged on the front and rear sides of the support frame. Among them, the display module 1 adopts the technology disclosed by the applicant in the prior art CN202221187436.2, which mainly comprises a hollow aluminum profile plate body, an LED display assembly arranged on the front of the plate body, and a PCB board arranged in the plate body. Therefore, the display module 1 itself has a small thickness. The support frame comprises two columns 21, a frame structure arranged between the two columns 21, and a base 22 arranged at the lower end of the two columns 21. A plurality of display modules 1 are directly installed on the front and back surfaces of the two columns 21 in the vertical direction. Unlike the relatively bulky box structure of the prior art, the thickness of the entire display screen is small, and the weight is light. The frame structure is mainly used for arranging an electric control box 3. The base 22 allows the display screen to be placed directly on the ground for use. At the same time, due to the light and thin characteristics of the entire display screen, two handles 23 are arranged on the opposite sides of the two columns 21, so as to facilitate the manual transfer of the display screen or the adjustment of the position of the display screen, and the use is more convenient.

[0026] Specifically, as shown in Figure 3 Each column 21 has a plurality of mounting grooves 211 arranged on the front and rear sides and in the vertical direction, and the display module 1 has a mounting piece arranged on the back of both sides to cooperate with the mounting groove 211. The opposite sides of the two columns 21 are provided with a connecting piece 4, and the connecting piece 4 extends into the mounting groove 211 and is connected with the mounting piece. In this way, through the cooperation of the mounting piece and the mounting groove 211, the accuracy of the display module installation position is ensured. During installation, the left and right mounting pieces on the back of the display module 1 are inserted into the mounting grooves 211 of the two columns 21 respectively, and then the mounting pieces are connected and fixed from the side of the column through the connecting piece 4. Among them, the connecting piece 4 can adopt a bolt, and a pull rivet is arranged on the mounting piece to realize the stable connection of the column 21 and the mounting piece. At the same time, the structure is easy to disassemble, and only the bolt needs to be removed to remove the display module 1 for maintenance from the front side.

[0027] As Figure 4As shown, the mounting member includes a main plate 51, and two insertion plates 52 vertically arranged on the same side of the main plate 51. The main plate 51 is connected to the back of the display module 1 by bolts and rivets. The insertion plate 52 is divided into two parts, which mainly improves the elasticity of the insertion plate 52 to facilitate installation. For example, during the insertion process of the insertion plate 52 into the mounting groove 211, there is a gap between the insertion plate 52 and the inner wall of the mounting groove 211, so that the insertion process is more smooth. When the fastening operation is performed by bolts and rivets, the insertion plate 52 is pulled towards the inner wall of the mounting groove 211 to ensure the fastening of the connection. In order to improve the efficiency of the connection operation between the main plate 51 and the display module 1, the upper and lower parts of the main plate 51 are connected to the back of the display module 1 by bolts and rivets, and the middle part of the main plate 51 is provided with a positioning hole, and the back of the display module 1 is provided with a positioning column 11, so that the positioning column 11 and the positioning hole are matched to speed up the alignment efficiency of the connection part between the main plate 51 and the display module 1. In addition, in order to facilitate the insertion of the insertion plate 52 into the mounting groove 211, the width of the mounting groove 211 in the horizontal direction is greater than the thickness of the insertion plate 52 in the direction. At the same time, in order to ensure the fastening of the connection between the insertion plate 52 and the mounting groove 211, the insertion plate 52 is closely attached to the inner wall of the mounting groove 211 near the outside.

[0028] Since the display screen is formed by a plurality of display modules 1 connected in series along the vertical direction to form a display surface, in order to avoid large gaps at the connection between adjacent display modules, affecting the quality of the display surface, the holes for arranging the connecting members on the stand 21 are vertical strip holes 212, so that the position of each display module has a certain adjustment space in the vertical direction, avoiding too large joint gap.

[0029] As shown in Figure 2 The frame structure includes an upper cross beam 241, a lower cross beam 242, and two vertical rods 243 arranged between the upper cross beam 241 and the lower cross beam 242, and an electric control box 3 is arranged between the two vertical rods 243. In order to improve the structural strength, a plurality of horizontal rods 244 are arranged between the vertical rod 243 and the stand 21 adjacent thereto. Moreover, in order to improve the maintenance efficiency, the electric control box 3 has two upper and lower parts, and each electric control box 3 is connected to different display modules.

[0030] In order to ensure the sealing effect of the connection between the display module 1 and the stand 21, and to prevent impurities from entering, the support frame is provided with a baffle 6 covering the end of the display module, including three groups of baffles on the left and right sides and the upper side, and the baffle 6 is installed by bolts. Therefore, at least two side baffles 6 need to be removed first, and then the connecting member 4 can be removed to disassemble the display module 1. As shown in Figure 5 Due to the existence of the connecting member 4, two support strips 61 are arranged on the baffles on both sides, and the space for accommodating the connecting member 4 is formed between the two support strips. In addition, in order to avoid the baffle 6 pressing the display components on the front of the display module, mainly the LED lamp, the baffle is also provided with a display component avoiding groove 62.

[0031] The above merely illustrates a preferred embodiment of the present application, which is one implementation based on the overall concept of the present application, and the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
