[0025] One end of the wire 11 is electrically connected to the side of the diverter 10, and the number of wires 11 is four; by setting the diverter 10, when multiple display screens are installed and fixed, the No. 1 power supply plug 6 is inserted into the No. 1 socket 8, and the No. 2 power supply plug 7 is inserted into the No. 2 socket 9. At this time, the diverter 10 is started, so that the diverter 10 can supply power to the No. 1 display screen 4 and the No. 2 display screen 5 through the No. 1 socket 8 and the No. 2 socket 9, thereby avoiding the problem that the current of the remaining display screens is disconnected when a single display screen fails, causing the remaining display screens to fail, thereby improving the stability of the LED splicing screen.

[0026] The front shape of the limit frame 2 is a cross, and the limit frame 2 is located in the middle of the shell 1; by setting the limit frame 2, when multiple display screens are installed and fixed, the limit frame 2 can limit the multiple display screens inside the shell 1, thereby avoiding the problem of mutual friction when the multiple display screens vibrate, thereby improving the stability of the positions of the multiple display screens.

[0027] The protective pad 3 is in close contact with the No. 1 display screen 4, and the material of the protective pad 3 is rubber material; by providing the protective pad 3, when the LED splicing screen moves and vibrates, the protective pad 3 can limit the moving position of the No. 1 display screen 4, so as to avoid the problem that the No. 1 display screen 4 is damaged due to friction with the inner wall of the shell 1 when the No. 1 display screen 4 vibrates, thereby improving the safety of the No. 1 display screen 4.

[0028] The filter mechanism 13 includes an air inlet 131, which is opened at the bottom of the inner cavity of the shell 1. A filter cover 132 is fixedly mounted on the bottom of the shell 1, and the material of the filter cover 132 is a synthetic fiber material. By setting the filter mechanism 13, when the airflow inside the shell 1 is discharged, the filter cover 132 can filter the airflow entering the shell 1, so that the dust accompanying the air can be blocked by the filter cover 132 to the outside of the shell 1, thereby avoiding the problem of dust accompanying the air into the shell 1, causing the inside of the shell 1 to become dirty, thereby improving the cleanliness of the inside of the LED splicing screen.

[0029] The closing mechanism 14 includes a baffle 141, which is movably sleeved inside the shell 1, and a top cover 142 is fixedly connected to the top of the baffle 141, and a bolt 143 is threadedly sleeved on the top of the top cover 142; by setting the closing mechanism 14, when the installation and fixation of multiple display screens are completed, the baffle 141 is sleeved inside the shell 1, and the bolt 143 is rotated at this time, so that the bolt 143 can pass through the top cover 142 to limit and fix the baffle 141 inside the shell 1, so that the baffle 141 can limit and fix the multiple display screens, thereby achieving the fixing effect of the display screens.

[0030] The heat dissipation mechanism 15 includes a protective cover 151, which is fixedly connected to the side of the shell 1. A rotating motor 152 is fixedly installed inside the protective cover 151, and a fan blade 153 is fixedly sleeved on the output shaft of the rotating motor 152. By setting the heat dissipation mechanism 15, when the LED splicing screen works for a long time and causes the temperature inside the shell 1 to rise, the rotating motor 152 is started, so that the rotating motor 152 can drive the fan blade 153 to rotate rapidly. At this time, the airflow inside the shell 1 can be quickly discharged to the outside of the shell 1 through the protective cover 151, thereby improving the heat dissipation speed inside the shell 1, that is, improving the stability of the LED splicing screen when it works for a long time.

[0031] The heat sink 16 is made of metal aluminum material, and there are three heat sinks 16, which are parallel to each other. By setting the heat sink 16, when the diverter 10 works for a long time and causes the internal temperature to rise, the heat inside the diverter 10 can be quickly discharged to the inside of the shell 1 through the heat sink 16, thereby avoiding the problem of the diverter 10 malfunctioning due to the high temperature caused by the long-term operation of the diverter 10, thereby improving the stability of the diverter 10 when working for a long time.

[0032] The working principle of an LED splicing screen provided by the utility model is as follows:

[0033] Step 1: First, when installing and fixing multiple display screens, insert the No. 1 power plug 6 into the No. 1 socket 8, and insert the No. 2 power plug 7 into the No. 2 socket 9. At this time, start the shunt 10, so that the shunt 10 can supply power to the No. 1 display screen 4 and the No. 2 display screen 5 through the No. 1 socket 8 and the No. 2 socket 9, thereby avoiding the problem that the current of the remaining display screens is disconnected when a single display screen fails, causing the remaining display screens to fail, thereby improving the stability of the LED splicing screen. When installing and fixing multiple display screens, the limit frame 2 can limit the multiple display screens inside the shell 1, thereby avoiding the problem of mutual friction when the multiple display screens vibrate, thereby The stability of the positions of multiple display screens is improved. When the LED splicing screen moves and vibrates, the protective pad 3 can limit the moving position of the No. 1 display screen 4, so that the No. 1 display screen 4 is prevented from rubbing against the inner wall of the shell 1 when vibrating, causing damage to the No. 1 display screen 4, thereby improving the safety of the No. 1 display screen 4. When the airflow inside the shell 1 is discharged, the filter cover 132 can filter the airflow entering the shell 1, so that the dust accompanying the air can be blocked to the outside of the shell 1 by the filter cover 132, thereby preventing the dust from entering the shell 1 with the air, causing the inside of the shell 1 to be dirty, thereby improving the cleanliness of the inside of the LED splicing screen;

[0034] Step 2: When the installation and fixation of multiple display screens are completed, the baffle 141 is sleeved inside the shell 1. At this time, the bolt 143 is rotated so that the bolt 143 can limit and fix the baffle 141 inside the shell 1 through the top cover 142, so that the baffle 141 can limit and fix the multiple display screens, thereby achieving the fixing effect of the display screens. When the LED splicing screen works for a long time and causes the temperature inside the shell 1 to rise, the rotating motor 152 is started so that the rotating motor 152 can drive the fan blades 153 to rotate rapidly. At this time, the airflow inside the shell 1 can be quickly discharged to the outside of the shell 1 through the protective cover 151, thereby improving the heat dissipation speed inside the shell 1, that is, improving the stability of the LED splicing screen when working for a long time. When the diverter 10 works for a long time and causes the internal temperature to rise, the heat inside the diverter 10 can be quickly discharged to the inside of the shell 1 through the heat sink 16, thereby avoiding the problem that the diverter 10 has a high temperature for a long time and causes the diverter 10 to fail, thereby improving the stability of the diverter 10 when working for a long time.

[0035] Compared with the related art, the LED splicing screen provided by the utility model has the following beneficial effects:

[0036] By setting the shunt 10, when multiple display screens are installed and fixed, the No. 1 power supply plug 6 is inserted into the No. 1 socket 8, and the No. 2 power supply plug 7 is inserted into the No. 2 socket 9. At this time, the shunt 10 is started, so that the shunt 10 can supply power to the No. 1 display screen 4 and the No. 2 display screen 5 through the No. 1 socket 8 and the No. 2 socket 9, thereby avoiding the problem that the current of the remaining display screens is disconnected when a single display screen fails, causing the remaining display screens to fail, thereby improving the stability of the LED splicing screen.
