[0035] As mentioned in the above background art, for existing LED display products, in order to reduce labor costs and improve the convenience of installation, a magnetic attraction method is often used to connect the cabinet and the module light board. Although the magnetic attraction iron frame in the prior art facilitates the installation of the module, it is a problem that those skilled in the art need to consider how to install the module of different thicknesses on the display cabinet through the magnetic attraction iron frame while making the surface of the module flush with the surface of the frame of the display cabinet to ensure the flat and beautiful screen surface of the LED display. Based on this, the inventors of the present application provide a module installation unit of an LED display cabinet and an LED display cabinet in one or more embodiments. The module installation unit of the LED display cabinet drives the magnetic attraction frame to move in the L-shaped groove through a driving mechanism, thereby adjusting the height difference between the top surface of the magnetic attraction plate and the top surface of the side plate, and making the height difference equal to the thickness of the module. After the module is adsorbed on the module installation unit through the magnetic attraction frame, the surface of the module is flush with the top surface of the side plate, thereby ensuring the flat and beautiful screen surface of the LED display with modules of different thicknesses. It is believed that it can solve one or more problems in the prior art.

[0036] In view of the above-mentioned technical problems, the present utility model provides a module installation unit of an LED display cabinet, as Figure 1-4 shown, including: a frame 1, the frame 1 includes a plurality of side strips 2, the plurality of side strips 2 are connected end to end to form the frame 1, the side strip 2 includes a bottom plate 3 and a side plate 4, the bottom of the side plate 4 is connected to one edge of the bottom plate 3 so that an L-shaped groove 5 is formed on the side strip 2, and the L-shaped grooves 5 on the plurality of side strips 2 communicate with each other to form an installation groove 6; a magnetic attraction frame 7, the magnetic attraction frame 7 for adsorbing the module 17 includes a plurality of magnetic attraction plates 8, the plurality of magnetic attraction plates 8 are connected end to end to form the magnetic attraction frame 7, and the magnetic attraction frame 7 is movably arranged in the installation groove 6 along the height direction of the side plate 4; and a driving mechanism, the driving mechanism is arranged on the bottom plate 3 to drive the magnetic attraction frame 7 to move along the height direction of the side plate 4.

[0037] Specifically, according to the thickness of the module 17 to be installed, the driving mechanism drives the magnetic attraction frame 7 to move in the installation groove 6 along the height direction of the side plate 4, thereby adjusting the height difference between the top surface of the magnetic attraction plate 8 and the top surface of the side plate 4, and making the height difference equal to the thickness of the module 17. After the adjustment is completed, the module 17 is adsorbed on the magnetic attraction frame 7 in the installation groove 6. Specifically, a metal strip can be arranged on the back of the module 17, and the module 17 is adsorbed on the magnetic attraction frame 7 through the metal strip.

[0038] Compared with the prior art, the module installation unit of an LED display cabinet of the present application drives the magnetic attraction frame 7 to move in the L-shaped groove through the driving mechanism, thereby ensuring the flat and beautiful screen surface of the LED display with modules 17 of different thicknesses.

[0039] In some embodiments, as Figure 2As shown, the driving mechanism includes an adjusting bolt 9. The screw of the adjusting bolt 9 passes through a threaded hole 10 formed in the bottom plate 3 and is connected to the magnetic attraction frame 7. By rotating the adjusting bolt 9, the screw of the adjusting bolt 9 moves in the threaded hole 10 along the height direction of the side plate 4, so that the height difference between the top surface of the magnetic attraction frame 7 and the top surface of the side plate 4 can be adjusted. After the adjustment is completed, the engagement of the screw with the threaded hole 10 plays a supporting role for the magnetic attraction frame 7. Specifically, there are multiple adjusting bolts 9, and the multiple adjusting bolts 9 are distributed along the length of the bottom plate 3, and the multiple adjusting bolts 9 are arranged in an interlaced manner, that is: not arranged in a straight line, thus ensuring the stability and balance of the force on the magnetic attraction frame 7.

The sliding groove 12 is a structure corresponding thereto, including a head receiving portion 19 and a rod receiving portion 20. Since the size of the rod portion 22 is smaller than the size of the head portion 21, and the size of the rod receiving portion 20 is smaller than the size of the head receiving portion 19, the size of the head portion 21 matches the size of the head receiving portion 19, and the size of the rod portion 22 matches the size of the rod receiving portion 20. The head portion 21 slides in the head receiving portion 19, and the rod portion 22 slides in the rod receiving portion 20.

Further, there are multiple sliding grooves 12 and multiple sliding strips 13. The multiple sliding grooves 12 are equally spaced along the length direction of the side plate 4, and the multiple sliding strips 13 are equally spaced along the length direction of the magnetic attraction plate 8. One sliding strip 13 is cooperatively arranged in one sliding groove 12. Through the multiple sliding grooves 12 and the multiple sliding strips 13, the stability of the magnetic attraction frame 7 is further ensured.

[0042] In some embodiments, as Figure 6 shown, a cross bar 14 is provided on the magnetic attraction frame 7. The two ends of the cross bar 14 are respectively connected to two opposite magnetic attraction plates 8. The structural strength of the magnetic attraction frame 7 is further increased by the cross bar 14. Specifically, there can be multiple cross bars 14. At the same time, the cross bar 14 also plays a role in supporting, enclosing and dissipating heat for the module 17. Specifically, the cross bar 14 can be made of a metal material.

[0043] In some embodiments, as Figure 6 and Figure 7 shown, heat dissipation columns 15 are provided on the horizontal bar 14, and the heat dissipation effect on the module 17 is further improved through the heat dissipation columns 15. Specifically, there may be a plurality of heat dissipation columns 15, and the plurality of heat dissipation columns 15 are evenly distributed on the horizontal bar 14.

[0044] In some embodiments, as Figure 6 shown, scale lines 16 are provided along the height direction on the inner wall of the side plate 4. The magnetic attraction frame 7 can be accurately adjusted to the required height through the scale lines 16. Further, there are multiple scale lines 16, and the multiple scale lines 16 are equidistantly distributed along the length direction of the side plate 4, and the level of the magnetic attraction frame 7 is ensured through the multiple scale lines 16.

[0045] In addition, the present utility model further provides an LED display screen box, as Figure 7 shown, including the module installation unit 18 of the above-mentioned LED display screen box, and there are a plurality of module installation units 18, and the plurality of module installation units 18 are spliced together.
