The adjusting assembly comprises a box adjusting platform arranged on the outer side wall of the side plate and a mounting seat arranged on the inner side wall of the side plate. The mounting seat is provided with a threaded adjusting hole adapted to the adjusting piece, and the threaded adjusting hole passes through the box adjusting platform. The die-cast box adopts an adjustment component, which includes a box adjustment platform and a mounting seat. The adjustment part passes through the box adjustment platform of the previous die-cast box and the box adjustment platform of the next die-cast box in sequence, and is threadedly connected to the mounting seat of the next die-cast box to splice two adjacent COB displays together. Moreover, since a connecting piece mounting angle is provided on the back of the die-cast box, the backs of adjacent COB displays are connected together through the connecting piece body. Compared with the existing technology, the splicing gap of adjacent COB displays can be adjusted by the adjustment component, which solves the technical problems of obvious splicing seams and unsatisfactory flatness of existing COB displays.

[0036] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0037] Example:

[0038] Reference Figures 1 to 3 This embodiment provides an indoor COB display screen, including a die-cast box body 1, a connecting piece body 2, an adjusting part 113, an adapter board body 3, a power supply body 4 and a COB display unit 6. The COB display unit 6 is magnetically matched with the die-cast box body 1. The adapter board body 3 and the power supply body 4 are installed in the space between the COB display unit 6 and the die-cast box body 1 to provide power and signals for the screen.

[0039] See Figures 2 to 5 The die-cast box 1 includes a back plate and side plates arranged around the edges of the back plate. The side plates are provided with an adjustment component 11. The adjustment component 11 includes a box adjustment platform 111 arranged on the outer wall of the side plate and a mounting seat 1120 arranged on the inner wall of the side plate. The mounting seat 1120 is provided with a threaded adjustment hole 112 adapted to the adjustment member 113, and the threaded adjustment hole 112 passes through the box adjustment platform 111.

[0040] In actual production applications, two groups of adjustment members 113 are usually provided, which are respectively installed on two adjacent side panels. When two adjacent COB display screens are spliced, the adjustment members 113 pass through the box adjustment platform 111 of the previous die-cast box 1 and the box adjustment platform 111 of the next die-cast box 1 in turn, and are threadedly connected to the mounting base 1120 of the next die-cast box 1, connecting the upper and lower side panels and the left and right side panels of the COB display screen with the adjacent COB display screens.

[0041] See Figure 3 and Figure 4 In some feasible solutions, multiple cabinet adjustment platforms 111 are provided on the side panels. The rear edges of the cabinet adjustment platforms 111 extend together, and the cabinet adjustment platforms 111 are higher than the plane of the outer wall of the side panels. Therefore, by simply controlling the flatness of the cabinet adjustment platforms 111, the flatness of the side panels of the COB display can be guaranteed, thereby improving the splicing accuracy of the display screen and improving the visual viewing effect. At the same time, due to the provision of the cabinet adjustment platforms 111 and the mounting base 1120, the side panels of the die-cast cabinet 1 can be made thinner, making the die-cast cabinet 1 light, thin and stable, and highly stable during splicing and not easily deformed.

[0042] It should be noted that the thickness of the box adjustment platform 111 is greater than the thickness of the side panel, and a mounting seat 1120 with a threaded adjustment hole 112 is provided on the inner side of the side panel. This not only makes the overall thickness of the frame of the die-cast box 1 smaller and thinner, but also ensures that the die-cast box 1 has sufficient mechanical strength, making it less likely to deform during the splicing process and having stable and reliable working performance. The provision of the box adjustment platform 111 also reduces the production difficulty of the die-cast box 1, and the flatness of the die-cast box 1 is higher. The box adjustment platform 111, the mounting seat 1120, and the adjustment member 113 are used in combination to improve the working stability of the die-cast box 1, increase the precision of splicing, and make the die-cast box 1 thinner.

[0043] In actual application, the adjusting member 113 includes a fastener with threads such as a bolt or a screw.

[0044] See Figure 1 In some feasible solutions, the connecting piece body 2 is a rectangular metal part, and each right-angle position on the back of the die-cast box 1 is provided with a connecting piece mounting angle 10. Each right-angle position of the connecting piece body 2 is provided with a threaded through hole 21. The fastener passes through the threaded through hole 21 and is threadedly connected to the connecting piece mounting angle 10 to splice adjacent COB displays together.

[0045] Continue reading Figure 1 The connecting piece installation angle 10 is a right-angle structure, and a first connecting hole 101 is provided at the intersection of the two right-angle sides, and second connecting holes 102 are also provided on both sides thereof. The aperture of the first connecting hole 101 is larger than the aperture of the second connecting hole 102.

[0046] See Figures 3 and 4 A magnet sheet 7 is provided on the back of the COB display unit 6, and a magnet mounting column 17 is provided on the front of the die-cast box body 1. The magnet mounting column 17 is installed with the magnet sheet 7. Therefore, the COB display unit 6 and the die-cast box body 1 are magnetically mounted together.

[0047] See Figure 3 and Figure 4 , a plurality of first ridges 13 for heat dissipation are provided on the back panel. A plurality of second ridges 16 are provided on the four edges of the front of the side panel. The second ridges 16 are in a right-angle shape and do not connect with each other. Third ridges 18 are evenly provided on the front of the back panel. The third ridges 18 are in a right-angle shape or a strip shape. Four right-angled third ridges 18 are combined into a cross-shaped structure to support the right-angle position of four adjacent COB display units 6. A magnet mounting column 17 is provided on the back panel at a position relative to each second ridge 16, and a magnet mounting column 17 is provided at each right-angled third ridge 18. A magnet mounting column 17 is provided on both sides of the strip-shaped third protrusion. A magnet sheet 7 is installed on the magnet mounting column 17 to magnetically cooperate with the COB display unit 6.

[0048] Due to the provision of the first ridge 13, the second ridge 16 and the third ridge 18, the COB display unit 6 and the die-cast housing 1 are magnetically engaged through the magnet sheet 7, ensuring that the COB display unit 6 and the die-cast housing 1 have sufficient contact surface for heat conduction. At the same time, a heat dissipation gap is reserved between the COB display unit 6 and the die-cast housing 1 to facilitate the discharge of hot air from the housing, resulting in better heat dissipation effect, suitable for indoor installation environment, and can improve the heat dissipation effect of the COB display screen and extend its service life.

[0049] See Figure 3 and Figure 4 In some feasible solutions, the adapter plate body 3 is provided with an air-avoidance hole 31 and a notch 34. The air-avoidance hole 31 is used to avoid the magnet mounting column 17, and the notch 34 is used to avoid the power supply body 4. The power supply body 4 is installed on the front of the die-cast box 1 through the power supply pressure strip 5.

[0050] Continue reading Figure 3 and Figure 4 In actual use, the back of the COB display unit 6 is provided with a first connection socket 61, and the adapter board body 3 is provided with a second connection socket 33 adapted thereto. The first connection socket 61 and the second connection socket 33 are both power and signal two-in-one sockets. The adapter board body 3 is also provided with a network cable socket 32.

[0051] See Figure 4 In order to improve the mechanical strength of the die-cast box 1, the front of the back plate is provided with reinforcing ribs 19. The reinforcing ribs 19 include horizontally arranged, longitudinally arranged and obliquely arranged ones. The obliquely arranged reinforcing ribs 19 are distributed at the upper and lower ends of the back plate.

[0052] participate Figure 3 The side panels are provided with wire holes 14 to allow cables to pass through. Positioning holes 15 are provided on the box adjustment platforms 111 of two adjacent side panels in one group, and positioning beads 150 are installed on the box adjustment platforms 111 of two adjacent side panels in another group. The positioning holes 15 and the positioning beads 150 cooperate to position the die-cast box 1 during the splicing process.
