Embodiment 1
[0028] For example figure 1 -example Figure 5 Shown:
[0029] The present invention provides a classical document image display device for distance education, its structure includes a display screen 1, a base 2, a support frame 3, the bottom of the support frame 3 is welded to the upper surface of the base 2, and the display screen 1 is installed The upper end position of the support frame 3; the display screen 1 includes a rear shell 11, a vent hole 12, and a display board 13, the vent hole 12 runs through the inner position of the rear shell 11, and the right side of the display board 13 is connected to the rear The left side of shell 11 fits together.
[0030] Wherein, the air hole 12 includes a frame a1, a rod body a2, an elastic strip a3, and a connecting block a4, the frame a1 and the connecting block a4 are an integrated structure, and the rod body a2 is engaged with the inside of the connecting block a4, so that The elastic bar a3 is wound around the outer surface ...
Embodiment 2
[0036] For example Figure 6 -example Figure 9 Shown:
[0037] Wherein, the frame a1 includes a frame body c1, a heat dissipation strip c2, and a ventilation cavity c3, the heat dissipation strip c2 runs through the inner position of the ventilation cavity c3, the ventilation cavity c3 is embedded in the inner position of the frame body c1, and the heat dissipation Strip c2 is made of aluminum metal with strong heat dissipation, through which heat dissipation strip c2 can introduce part of the heat passing through frame c1 into the interior of ventilation cavity c3, and heat dissipation strip c2 can conduct heat to the inside of heat dissipation strip c2 The heat is initially dissipated.
[0038]Wherein, the heat dissipation bar c2 includes a contact reducing groove c21, a connecting rod c22, and a cooling groove c23. The contact reducing groove c21 is embedded in the inner side of the connecting rod c22, and the cooling groove c23 is fixed inside the connecting rod c22. N...
