DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0030] Example 1: An outdoor LED rental screen, see Figure 1 , Figure 5 , Fig. 9 and Fig.10As shown, it includes an LED display screen 1, a mounting frame 101 and a control center 102. The LED display screen 1 is installed on the front side of the mounting frame 101 by bolt connection. The control center 102 is installed in the mounting frame 101. The control center 102 is electrically connected to the LED display screen 1. It also includes an installation box 14, a power grid 15 and an attractant lamp 16. The installation box 14 is installed on both sides of the rear of the mounting frame 101 by bolt connection. Three attractant lamps 16 that can emit light of a specific wavelength to attract mosquitoes and flies are installed in the mounting box 14. The power grid 15 is installed on the mounting box 14 by bolt connection.

[0031] When the LED display screen 1 is used outdoors, since the bright light emitted by the LED display screen 1 has the characteristic of attracting mosquitoes and flies, these insects may interfere with the audience's experience, especially mosquitoes may bite the audience, affecting their viewing effect. At this time, by turning on the attraction lamp 16 and supplying power to the power grid 15, the attraction lamp 16 emits light of a specific band, and mosquitoes and flies will be attracted to the light source. When they come into contact with the energized power grid 15, they will be instantly killed by the current on the power grid 15, effectively reducing the number of mosquitoes and flies, thereby ensuring a comfortable viewing environment for the audience.

[0032] Example 2: Based on Example 1, refer to Figure 1-Figure 3 As shown, it also includes a plurality of support frames 2 that are fixedly connected by a first mounting plate 3 to form a steel structure bracket, and a connecting plate 7 is installed on the rear side of the mounting frame 101 by bolt connection, wherein four support frames 2 are installed with a second mounting plate 4 by bolt connection, and a back plate 5 is commonly installed on the four second mounting plates 4 by bolt connection, and a keel 6 is installed on the back plate 5 by bolt connection, and the keel 6 is fixedly connected to the connecting plate 7 by bolt connection.

[0033] When it is necessary to give a speech or presentation outdoors, multiple support frames 2 are freely combined and spliced, and the first mounting plate 3 is used to fix these spliced ​​support frames 2 to ensure the stability of the structure. Next, two support frames 2 are selected in the upper and lower directions, and the second mounting plates 4 are installed thereon. The back plate 5 is installed on all the second mounting plates 4 to form a basic frame. The keel 6 is further installed on the back plate 5 to improve the stability and bearing capacity of the entire structure. Then, the connecting plate 7 is assembled on the rear side of the installation frame 101. By firmly fixing the connecting plate 7 on the keel 6, the installation frame 101 can be fixed, ensuring that the LED display screen 1 can be displayed safely. Finally, the LED display screen 1 can display various required contents by operating the control center 102.

[0034] See also Figure 5-Figure 8As shown, it also includes a water tank 8 installed in the installation frame 101 by means of bolt connection, the water tank 8 is connected and communicated with a guide pipe 10, the guide pipe 10 is fixedly connected with a water pump 9, the guide pipe 10 is fixed to the top of the installation frame 101, and a plurality of water outlet holes 1001 are opened on the guide pipe 10, an electric slide rail 11 is installed on one side of the installation frame 101 by means of bolt connection, a slider 12 is provided in the electric slide rail 11 for sliding up and down, and a cleaning cotton 13 for wiping dust is fixedly connected to the side of the slider 12 close to the LED display screen 1 by means of bonding.

[0035] In view of the fact that dust easily accumulates on the surface of the LED display screen 1 used outdoors, in order not to affect the audience's viewing experience, by starting the water pump 9, the water in the water tank 8 is pumped out through the guide pipe 10, and evenly sprayed on the surface of the LED display screen 1 through a series of water outlet holes 1001 to moisten and soften the attached dust, and then the electric slide rail 11 is activated to make the slider 12 drive the cleaning cotton 13 to slide up and down. The cleaning cotton 13 will fit the surface of the display screen to effectively scrape and clean the dust, thereby maintaining the clarity and viewing experience of the LED display screen 1.

[0036] See also Fig.11 As shown, it also includes a support plate 17 that is slidably inserted into each surface of the lower part of the support frame 2, and a rotating plate 18 is rotatably arranged on the support plate 17. The end of the rotating plate 18 away from the support plate 17 is locked to the support frame 2 by bolt connection, and a pad 19 is installed on the bottom of the support plate 17 by welding.

[0037] After completing the assembly and splicing of each support frame 2, slide the three support plates 17 along the support frames 2 at the bottom of both sides into place, then rotate the rotating plate 18 and snap it onto the corresponding support frame 2 to form a stable connection point, and finally use bolts to fasten the rotating plate 18 to the support frame 2 to ensure a tight combination of the structure. The triangular bracket formed by the support plate 17 and the rotating plate 18 can enhance the stability of the entire frame, provide additional supporting force, and ensure the structural safety of the LED display screen 1 when used outdoors.

[0038] See also Figure 4 , Figure 8 and Fig.11 As shown, a weight block 20 is installed on the support plate 17 by bolt connection; four connection blocks 21 are installed between the back plate 5 and the connection plate 7 by bolt connection; and a water collecting plate 22 is installed on the upper part of the installation frame 101 by welding.

[0039] The function of the weight-increasing block 20 is to increase the weight of the support plate 17, thereby lowering the center of gravity of the entire structure, effectively preventing the support frame 2 from tipping over due to external force, and ensuring the stability of the LED display screen 1; the connection block 21 is used to strengthen the bonding strength between the back plate 5 and the connection plate 7 to prevent the two from accidentally separating during use, thereby preventing the mounting frame 101 from falling off, and further avoiding the risk of damage to the LED display screen 1; the water flow ejected from the water outlet 1001 of the guide pipe 10 is gathered by the water collecting plate 22 to ensure that the water can be directly sprayed onto the surface of the LED display screen 1 for effective cleaning, while avoiding unnecessary waste of water resources and keeping the site clean.
