[0002] In various commercial centers or stage performances, large LED display screens are usually used for event promotion. Such LED display screens are usually assembled by multiple display modules in a display box. When assembling the display modules in the display box, there must be a certain assembly gap between two adjacent display modules. When light irradiates from the back of the display box, the light will project from the gap of the display module to the front of the display, resulting in light leakage, which seriously interferes with the display picture.

[0003] Therefore, in order to solve the problem of light leakage in the spliced screen, the prior art usually sets light-blocking strip plates on the module assembly box to prevent light transmission. However, this light-blocking method not only limits the structural variability of the display box, but also increases the cost and improves the manufacturing difficulty. Content of the Utility Model

The connecting ribs are arranged in the box body, and a number of blind hole hollow columns for installing the display lamp board are provided on the connecting ribs.

[0009] Further, a number of rib grooves are provided on the concave surface of the box body, and the connecting ribs are fitted and installed in the rib grooves.

[0010] Further, the box body is a metal box, and the mounting frame is made of plastic.

[0011] Further, at least one connection sleeve for electrically connecting the display lamp board is provided on the mounting frame, a connection port is formed on the surface of the box body, and the connection sleeve is inserted into the connection opening.

[0012] In summary, the beneficial effects of the present utility model are as follows: by providing a square bottom shell, and respectively providing a rib and a groove on two adjacent sides of the bottom shell, and making the height of the rib greater than the gap width when two adjacent bottom shells are spliced, when the LED display modules are spliced, the rib on the side of the bottom shell can be fitted into the groove on the side of the bottom shell to be spliced therewith, so that the splicing gap between two adjacent LED display modules can be filled and blocked by the rib, thereby avoiding light leakage caused by light penetrating from the splicing gap of the display module to the front of the display screen.

[0022] like Figures 1 to 4 As shown, an LED display module with anti-side light leakage can prevent light from being transmitted from the splicing gap of the display module to the front of the display screen to cause light leakage. It has a simple structure and is easy to produce and install. At the same time, it can also improve the splicing strength between the display modules.

[0023] The LED display module of this embodiment includes a bottom shell 1 and a display light board 2 installed in the bottom shell 1. Each LED display module can be spliced through the bottom shell 1 and installed in the display screen box, and display is performed through the display light board 2. Figures 1 to 2 As shown, the bottom shell 1 of this embodiment is a rectangular structure that is easy to splice, and includes two horizontal side edges and two vertical side edges. In this embodiment, two adjacent side edges, one horizontal and one vertical, are grouped together; Figure 2 As shown, in this embodiment, one group of adjacent sides is respectively provided with convex strips 11, and another group of adjacent sides is respectively provided with grooves 12 adapted to the convex strips 11, so that when the LED display modules are spliced, the convex strips 11 on the sides of the bottom shell 1 can be embedded in the grooves 12 of the adjacent bottom shell 1, thereby shielding the gap when the two LED display modules are spliced, and preventing light from being projected through the gap. The structure is simple and easy to produce and install, and through the cooperation of the convex strips 11 and the grooves 12, stable splicing between the LED display modules is achieved, which can improve the splicing strength.

[0024] Furthermore, the height of the convex strip 11 of this embodiment is greater than the gap width when the bottom shells 1 of two adjacent LED display modules are spliced, so that the gap after the LED display modules are spliced can be completely filled and shielded by the convex strip 11, thereby effectively avoiding the transmission of light and achieving complete shielding of the optical fiber.

[0025] As Figure 3 shown, on one side surface of the bottom shell 1 of this embodiment, there is an installation groove 13. The display lamp board 2 can be fitted and installed into the installation groove 13 to be connected with the bottom shell 1 to form an LED display module, and the installation method is convenient.

[0026] As Figure 3 and Figure 4 shown, in order to achieve the stable installation of the display lamp board 2, the bottom shell 1 of this embodiment includes a box body 14 and an installation frame 15 installed on the box body 14. Among them, the box body 14 and the installation frame 15 can fix the display lamp board 2, and the box body 14 can support the installation frame 15. The combination of the two realizes the stable installation of the display lamp board; further, one surface of the box body 14 of this embodiment is a concave surface, and the installation frame 15 is assembled in the concave surface of the box body 14 and combined with the box body 14 to form an installation groove 13. The display lamp board 2 can be fitted in the installation groove 13 and stably connected in the installation groove 13 through the installation frame 15, so as to achieve the stable installation of the display lamp board 2.

[0027] Specifically, as Figure 3 and Figure 4 shown, the installation frame 15 of this embodiment includes two end heads 151 and connecting ribs 152 arranged between the two end heads 151. When the installation frame 15 is connected to the box body 14, the two end heads 151 of the installation frame 15 can be respectively connected to both ends of the box body 14, realizing the stable connection between the installation frame 15 and the box body 14. At the same time, the connecting ribs 152 are arranged in the concave surface of the box body 14, and a number of blind hole hollow columns 153 are provided on the connecting ribs 152. After the display lamp board 2 is installed into the installation groove 13, it can be connected through the blind hole hollow columns 153 on the connecting ribs 152, so as to achieve the stable installation of the display lamp board 2, and the installation method is convenient.

[0028] In addition, as Figure 4 shown, a number of rib grooves 141 are also provided in the concave surface of the box body 14 of this embodiment, so that the connecting ribs 152 located in the concave surface of the box body 14 after the installation frame 15 is assembled with the box body 14 can be fitted into the rib grooves 141, which can further improve the connection strength between the installation frame 15 and the box body 14, thereby improving the stability of the blind hole hollow columns 153 and preventing the blind hole hollow columns 153 from falling off and affecting the stable installation of the display panel.

[0029] The box body 14 of this embodiment is a metal box, specifically a stretched aluminum plate part, and the installation frame 15 is made of plastic as a whole, which can improve the overall strength of the shell formed by the combination of the box body 14 and the installation frame 15, extend the service life, and can reduce the overall weight of the shell, facilitating installation and production.

[0030] As Figure 1 、 Figure 3 and Figure 4As shown in the figure, two connecting sleeves 154 are provided on the mounting frame 15 of this embodiment. The connecting sleeve 154 is of a hollow structure, enabling the connecting wire or connector of the display lamp panel 2 to be connected to the display screen box body through the connecting sleeve 154. The connection method is convenient, and the connecting wire or connector can be protected through the connecting sleeve 154, thereby improving the overall service life of the LED display module of this embodiment. Moreover, a connection opening 142 is provided on the box body 14 of this embodiment. The connecting sleeve 154 can be inserted into the connection opening 142 to avoid affecting the splicing between the box body 14 and the mounting frame 15, ensuring the stable connection between the box body 14 and the mounting frame 15.

[0031] In summary, the working principle of this embodiment is as follows: In this embodiment, a square bottom shell 1 is provided, and a rib 11 and a groove 12 are respectively provided on two adjacent sides of the bottom shell 1. At the same time, the height of the rib 11 is greater than the gap width when two adjacent bottom shells 1 are spliced. When the LED display modules are spliced, the rib 11 on the side of the bottom shell 1 can be fitted into the groove 12 on the side of the bottom shell 1 to be spliced therewith. Thus, the splicing gap between two adjacent LED display modules can be filled and blocked by the rib 11, thereby preventing light from leaking through the splicing gap of the display module to the front of the display screen, and the structure is simple and convenient for production and installation.
