Problems solved by technology

[0004] However, when the projector is projected on a demonstration device such as a curtain, it needs a path for light transmission, and the platform for teachers to stand on the podium is limited, and most teachers habitually walk on the platform, which is very easy to block The projector and the screen either prevent the projector from projecting images on the screen, so that all students cannot watch the projected content, or block the students' sight at a certain angle, so that some students can see the projected content on the screen, while others Some students were unable to see what was projected on the screen
These reasons will affect the learning situation of students and produce bad teaching effect.

Embodiment 1

[0033] The example is basically as attached figure 1 The shown multifunctional teaching demonstration device includes a slide rail 5 arranged on the platform 1, and two groups of display units are slidably connected on the slide rail 5, and each group of display units includes a slide plate 14 that slides along the slide rail 5, A screen 3 and a projector 4 arranged in front of the screen 3 are installed on the slide 14;

[0034] The bottom end of the slide rail 5 is covered with a foot pad 29 composed of the air bag 6 , the hydraulic bag 7 and the rubber sheet on the entire platform 1 . Whole foot pad 29 as figure 1 As shown, evenly distributed stepping units are formed, and the stepping units extend from the inside of the slide rail 5 to the platform 1 outside the slide rail 5 . When the teacher steps on a pedaling unit, the airbag 6 in the pedaling unit will be squeezed, so that the inflation of the balloon between the slide rails 5 becomes convex, and the convex balloon ...

Embodiment 2

[0046] Different from Embodiment 1, the projector 4 and the screen 3 are not installed together, and the two cannot be linked together. The balloon 6 includes a first balloon 15 and a second balloon 16 .

[0047] Specifically, as image 3 and Figure 4 As shown, the bottom end of the projector 4 is screwed with a support base 33 , and the bottom end of the support base 33 is hinged on the desk 2 through pins, which is convenient for installation and does not affect the support base 33 to drive the projector 4 to deflect. The support seat 33 can be arranged on the platform 1 or on the table 2 , and being arranged on the table 2 can avoid occupying the position of the platform 1 and avoid affecting the teacher's walking on the platform 1 . A rectangular block is integrally formed in the middle of the support base 33, the first cylinder 34 and the second cylinder 35 are respectively installed on both sides of the rectangular block, the first cylinder 34 on the left and the seco...

Abstract

The present invention discloses a functional teaching demonstration device. The device comprises a slide rail arranged on a platform, the slide rail is slidingly connected with two sets of display units, each display unit comprises one curtain and one projector arranged at the front portion of one curtain; the bottom end of the slide rail is provided with a plurality of air bags capable of pushingthe display units to move; all the air bags are connected together to form foot pads covering the surface of the platform; one hydraulic pressure bag filled with clear water are arranged at intervalsbetween each two air bags, and all the hydraulic pressure bags communicate to one another; the hydraulic pressure bags located at one sides of the foot pads are connected with a discharging tube extended above a teacher's desk; and a water cup configured to hold water is arranged at the lower portion of the discharging tube.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to a multifunctional teaching demonstration device. Background technique [0002] The writing board is an indispensable demonstration device in teaching work. The blackboard is an early type of writing board, but since it is necessary to write with chalk when using the blackboard, and the chalk is prone to problems such as falling ash, which greatly affects the environment. Therefore, chalk and blackboards are gradually replaced by water-based pens and whiteboards. [0003] With the increasing use of electronic equipment such as projectors in teaching, teachers rarely use water-based pens and whiteboards in class, but use PPT courseware prepared before class to explain. This saves the teacher's time for writing on the whiteboard and effectively improves the efficiency of the class. [0004] However, when the projector is projected to a presentation device such as a curtain, ther...
