The depth of the positioning hole is adapted to the length of the positioning post.

[0008] By adopting the above technical solution, the fan can be connected to the positioning hole of the extension plate through the positioning post.

[0009] Preferably, the fan is rectangular in shape and consists of multiple cooling fans, with the fan on the left side of the frame being an exhaust fan and the fan on the right side of the frame being an intake fan.

[0010] By adopting the above technical solution, the right fan can blow external cool air into the frame, and the left fan can draw heat out of the frame, thereby achieving the purpose of heat dissipation for the display screen inside the frame.

[0011] Preferably, the connecting plate is a rectangular plate, the length of the connecting plate is adapted to the distance between the two baffles, and there are two baffles, which are respectively welded to the left and right sides of one side of the fixing block.

[0012] By adopting the above technical solution, the two baffles can block the gap between the two internal connecting plates.
