Problems solved by technology

[0002] With the progress of the times, the establishment of mathematical models has gradually increased. Since mathematical models can convert concepts into specific images for display and can solve various practical problems, the establishment of mathematical models is indispensable. In teaching, it is not easy to understand when displaying geometric models and function curves, so it is easy to understand by displaying them on the display screen. However, in the prior art, the mathematical model is rotated to display the teaching equipment, and the mathematical model is displayed through the display screen. Since the display screen itself has heat dissipation pores, and chalk is used in the classroom, there is a lot of dust in the classroom, so that impurities such as dust continue to invade the display screen through the pores, resulting in excessive dust accumulation inside the display screen, resulting in yellowing of the screen display phenomenon

Embodiment 1

[0028] as attached figure 1 to attach Figure 6 Shown:

[0029] The present invention provides a mathematical model rotation display teaching equipment, the structure of which includes: a control box 1, a display mechanism 2, a rotating frame 3, the upper end surface of the control box 1 and the lower end surface of the display mechanism 2 are detachably installed, the The lower end of the swivel frame 3 is nested inside the control box 1 .

[0030] Wherein, the display mechanism 2 includes a cooling device 21, an engaging plate 22, a base 23, a knob 24, and a display screen 25. The left end surface of the heat dissipating device 21 is welded to the right end surface of the connecting plate 22, and the connecting plate 22 is connected to the base 23 is an integrated mechanism, the outer ring of the right end of the knob 24 is embedded in the inner side of the connecting plate 22 , and the display screen 25 is detachably installed on the inner side of the connecting plate 22...

Embodiment 2

[0038] as attached Figure 7 to attach Figure 9 Shown:

[0039] The present invention provides a mathematical model rotation display teaching device, the inner cavity a3 includes a casing c1, a connecting pipe c2, a pooling layer c3, and an air inlet c4, the casing c1 and the air inlet c4 are an integrated structure, the One end of the connecting pipe c2 is embedded in the inner side of the pooling layer c3, the pooling layer c3 is fixedly installed in the inner cavity a3, and the air inlet c4 is connected to the pooling layer c3, and the upper connecting pipe c2 is located on the left side of the lower connecting pipe c2 On the other side, when the equipment is not in use, the dust will fall downward due to the gravitational force, and when the equipment is in use, the gas emitted by the connecting pipe c2 at the upper end can blow the dust accumulated on the leftmost side, thus avoiding the dust for a long time Accumulated inside the cavity a3.

Abstract

The invention provides a mathematical model rotating display teaching equipment, the structure of which includes: a control box, a display mechanism, a rotating frame, the upper end surface of the control box and the lower end surface of the display mechanism are detachably installed, and the lower end of the rotating frame is nested in the control box In the present invention, when the display screen is displayed, the radiator in the display screen can blow the inside of the display screen, thereby blowing the gas into the heat dissipation device, so that the swing block rotates around the central axis, resulting in There is a gap between the swing block and the movable chamber, and the gas can flow through the gap, so as to discharge the gas. When the swing block rotates, the swing block exerts a pressing force on the air bag, and when the equipment is stopped, the air bag exerts pressure on the swing block. Push it so that the oscillating block fits and squeezes the movable cavity, so as to avoid blocking the cooling holes of the display screen, and prevent dust from entering the display screen through the cooling holes and accumulating inside the display screen, resulting in yellowing of the screen and other displays. Phenomenon.
