Problems solved by technology

[0003] Since the display screens of classical literature images for distance education are usually placed in the exhibition hall for a long time, if the exhibition hall has not been cleaned for a long time, it is easy for the spiders in the exhibition hall to spin their webs in the back-end air holes of the display screens for classical literature images for distance education , if it is not cleaned up in time, it is prone to decline in the heat dissipation rate of the air holes of the distance education classical literature image display screen

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...

Abstract

The invention discloses a classical literature image display device for distance education, which structurally comprises a display screen, a base and a support frame, the bottom of the support frame is welded with the upper surface of the base, the display screen is mounted at the upper end of the support frame, and a rod body can swing along a connecting block through inertia force generated when the base moves for a long distance. Through cooperation of elastic strips, the rod body can repeatedly swing along the connecting block, so that the rod body can pull down spider silk at the outer end of the inner wall of the frame, and the situation that spiders can knot spider silk screens at the outer ends of the inner walls of the air holes, and heat dissipation of the air holes is slow due to long-time accumulation is effectively avoided; and part of heat passing through the interior of the frame can be guided into the ventilation cavity through the heat dissipation strips, the contact area between the connecting rods and the outside can be increased through cooperation of the contact reducing grooves and the cooling grooves, and therefore the heat dissipation speed of the heat dissipation strips can be increased.

Description

technical field [0001] The invention relates to the field of distance education, in particular to a classical document image display device for distance education. Background technique [0002] The classical literature image display screen for distance education is mainly used for displaying classical literature images, and can be connected to the Internet to achieve remote delivery, and has the function of cross-regional movement. It is a common device in life. Based on the above description, the inventor It is found that an existing distance education image display device for classical documents mainly has the following deficiencies, for example: [0003] Since the display screens of classical literature images for distance education are usually placed in the exhibition hall for a long time, if the exhibition hall has not been cleaned for a long time, it is easy for the spiders in the exhibition hall to spin their webs in the air holes at the back end of the display screen...
