[0026] When the current LED display cabinet is spliced, the bracket will slide in the slide groove opened inside the main bracket. The internal structure of the slide groove is simple, which makes it inconvenient to fix the bracket. If the main bracket needs to be installed at an angle, it is easy to cause the bracket to slide, thereby affecting the stability of the LED display cabinet installation.

[0027] See also Figure 1-Figure 5 As shown, the device includes a hanger body 1, the top of which is fixedly connected with a fixing plate 12 for assisting the hanging installation, an inner groove 11 is opened in the middle of the hanger body 1, a plurality of sliding frames 13 are slidably arranged inside the inner groove 11, a display screen box 14 is connected to the top of two adjacent sliding frames 13, a plurality of sliding frames 13 are internally provided with fastening components 2 for assisting the fixing inside the inner groove 11, and a limiting component 3 is fixedly connected to the surface of the plurality of sliding frames 13.

[0028] First, the specific structure of the fastening assembly 2 is disclosed. The fastening assembly 2 includes a movable groove 22 opened inside the sliding frame 13, the inner wall of the movable groove 22 is fixedly connected to an electric cylinder 23, the inner wall of the electric cylinder 23 is movably connected to a piston rod 24, the end of the piston rod 24 away from the electric cylinder 23 is fixedly connected to a fastening block 25, and the inner wall of the inner groove 11 is provided with a plurality of fastening holes 21. When the sliding frame 13 slides to a certain position and needs to be fixed, the electric cylinder 23 is started to drive the piston rod 24 movably connected to the inside of the electric cylinder 23 to slide inside the movable groove 22, thereby driving the fastening block 25 fixedly connected to the end of the piston rod 24 to be inserted into the fastening hole 21 opened on the inner wall of the inner groove 11, thereby improving the fixing effect of the sliding frame 13 inside the inner groove 11, wherein the electric cylinder 23 is a remote control wireless structure, and the electric cylinder 23 can be remotely controlled within a certain distance, so as to facilitate the realization of automatic control.

[0029] Next, the specific structure of the limit assembly 3 is disclosed. The limit assembly 3 includes an extended rounded rod 32 fixedly connected to the top and bottom of the sliding frame 13. The upper and lower inner walls of the inner groove 11 are provided with limit grooves 31, and the surface of the extended rounded rod 32 is in contact with the inner wall of the limit groove 31. By using the limit grooves 31 provided on the upper and lower inner walls of the inner groove 11 and the extended rounded rod 32 fixedly connected to the upper and lower ends of the sliding frame 13, the sliding frame 13 can stably slide inside the hanger body 1, effectively improving the activity stability of the sliding frame 13.

[0030] The improvement of this embodiment lies in: first, by setting the fixing plate 12 on the top of the hanger body 1, the hanger body 1 is easy to be hung and installed, and the sliding frame 13 can be used to fix the display screen box 14. Through the inner groove 11, the display screen box 14 can be slidably installed inside the hanger body 1, and the limiting grooves 31 provided on the inner walls of the upper and lower sides of the inner groove 11 and the extended rounded rods 32 fixedly connected to the upper and lower ends of the sliding frame 13 are used to make the sliding frame 13 stably slide inside the hanger body 1. When the sliding frame 13 slides to a certain position and needs to be fixed, the electric cylinder 23 is started to drive the piston rod 24 movably connected to the inside of the electric cylinder 23 to slide inside the movable groove 22, thereby driving the fastening block 25 fixedly connected to the end of the piston rod 24 to be inserted into the fastening hole 21 provided on the inner wall of the inner groove 11, thereby improving the fixing effect of the sliding frame 13 inside the inner groove 11.

[0031] Considering the clamping stability of the fastening block 25 in the fastening hole 21, in order to further improve the clamping effect of the fastening block 25, Figure 2-Figure 5 As shown, the inner walls of the plurality of fastening holes 21 are fixedly connected with elastic clamping pads 4 for clamping the fastening blocks 25 .

[0032] The improvement lies in that: by setting an elastic clamping pad 4 on the inner wall of the fastening hole 21, when the fastening block 25 enters the interior of the fastening hole 21, the elastic clamping pad 4 can assist in clamping the fastening block 25, thereby effectively improving the clamping effect of the fastening block 25, and then improving the splicing and installation stability of the display screen box 14.

[0033] Since the fastening block 25 needs to be clamped inside the elastic clamping pad 4, in order to protect the elastic clamping pad 4 when it is used and reduce the situation of unstable clamping caused by damage to the surface of the elastic clamping pad 4, the Figure 2-Figure 5 As shown, one end of the fastening block 25 away from the piston rod 24 is fixedly connected to an extension page plate 5, and the extension page plate 5 is made of elastic material.

[0034] The improvement lies in that when the fastening block 25 slides toward the fastening hole 21 driven by the piston rod 24, the extension page plate 5 connected to the end of the fastening block 25 will first fit with the elastic clamping pad 4. Under the push of the piston rod 24, the extension page plate 5 made of elastic material will pass through the elastic clamping pad 4 and be located on the surface of the hanger body 1. At this time, the extension page plate 5 will cover the surface of the fastening hole 21 to protect the elastic clamping pad 4.

[0035] In summary, the working principle of the present invention is as follows: first, by setting the fixing plate 12 on the top of the hanger body 1, the hanger body 1 is easy to be hung and installed, and the display screen box 14 can be fixedly installed by using the sliding frame 13. Through the inner groove 11, the display screen box 14 can be slidably installed inside the hanger body 1, and the limiting grooves 31 provided on the inner walls of the upper and lower sides of the inner groove 11 and the extended rounded rods 32 fixedly connected to the upper and lower ends of the sliding frame 13 are used to make the sliding frame 13 stably slide inside the hanger body 1. When the sliding frame 13 slides to a certain position and needs to be fixed, the electric cylinder 23 is started to drive the piston rod 24 movably connected to the inside of the electric cylinder 23 to slide inside the movable groove 22, thereby driving the fastening block 25 fixedly connected to the end of the piston rod 24 to be inserted into the fastening hole 21 provided on the inner wall of the inner groove 11, thereby improving the fixing effect of the sliding frame 13 inside the inner groove 11;

[0036] When the fastening block 25 slides toward the fastening hole 21 driven by the piston rod 24, the extended page plate 5 connected to the end of the fastening block 25 will first fit with the elastic clamping pad 4. Under the push of the piston rod 24, the extended page plate 5 made of elastic material will pass through the elastic clamping pad 4 and be located on the surface of the hanger body 1. At this time, the extended page plate 5 will cover the surface of the fastening hole 21 to protect the elastic clamping pad 4.
