Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a teaching podium to solve the problem that teachers use chalk to write on the blackboard, and the chalk heads are often piled up on the blackboard groove or podium table. Students clean regularly, and it is easy for developing students to inhale chalk dust, causing micro-infection of the respiratory tract and affecting body functions, while the chalk tip is hard, which is easy to cause material accumulation and difficult to handle, and the waste of large pieces of chalk tip is discarded, which seriously pollutes the ecological environment , and the dust particles are densely dispersed, it is easy to cause the teacher's palm to stick to the chalk box and chalk particles placed on the podium for a long time

Embodiment 1

[0033] see Figure 1-Figure 6, the present invention provides a teaching platform, the structure of which includes: side drawer 1, chalk storage chute 2, podium table slot block 3, central control button seat 4, display screen 5, keyboard chute 6, power distribution cabinet 7 , the chalk storage chute 2 is nested in the right side of the podium table slot block 3 and is on the same level, the keyboard chute 6 is mechanically connected with the podium table slot block 3, and the side pull drawer 1 is inserted into the On the right side of the podium table slot block 3, the central control button base 4 and the display screen 5 are installed inside the podium table slot block 3 and are on the same level, and the podium table slot block 3 is nested in the power distribution cabinet 7 On the top, the chalk storage chute 2 is provided with a powder tube rolling brush seat 2A, a sliding shaving support sweeping frame 2B, a slideway storage groove 2C, a shuttle block rail frame 2D, a...

Embodiment 2

[0040] see Figure 1-Figure 6 , the present invention provides a kind of platform for teaching, other respects are identical with embodiment 1, and difference is:

[0041] see figure 2 , the chalk head holder 2E is composed of a clamping bar wheel groove 2E1, a strip seat 2E2, and a damping column block 2E3. The damping column block 2E3 is provided with two and is close to the right side of the strip seat 2E2. The clamping rod wheel groove 2E1 is installed inside the damping column block 2E3 and is on the same vertical plane, and the damping column block 2E3 is inserted through the clamping rod wheel groove 2E1 to form the pretreatment operation effect of crushing the chalk tip on the side.

[0042] see Image 6 , the clamp bar wheel groove 2E1 is composed of a square blade holder 2E11, a wheel groove seat 2E12, a clamp wheel body 2E13, and a long-axis clamp rod 2E14. The square blade holder 2E11 is inserted into the inside of the wheel groove seat 2E12. The blade holder 2...

Abstract

The invention discloses a teaching platform, which structurally comprises a side-pull drawer, a chalk storage sliding groove, a platform table groove block, a central control key base, a display screen, a keyboard sliding groove and a power distribution cabinet. The chalk storage sliding groove is matched with the platform table groove block, the slide way storage groove of the chalk box is formedin the side of the platform table groove block for embedded storage operation, the chalk lifting operation of the chalk tube rolling brush seat is guaranteed, and convenience is provided for teachersto take chalks for writing; chalk heads and chalks are placed in the chalk head clamping seat and the chalk powder suction frame groove disc in the later period, cutting and reshaping of the hard block and collecting of the powder for chalk wrapping are facilitated, and material waste is avoided; when classroom teaching is finished, the chalk box is recycled, active cleaning of students is avoided, chalk shaking and rolling brush operation is formed through sliding and pushing of the inner groove, chalk is ensured to be reshaped and integrated after powder is collected, and the chalk recycling and feedback operation effect of a teaching platform in the later period is guaranteed.

Description

technical field [0001] The invention is a platform for teaching, which belongs to the field of teaching equipment. Background technique [0002] The teaching podium is often used to provide teachers with teaching books and lesson plans to improve the overall convenience of blackboard teaching. It is convenient to turn around and take chalk from the chalk box on the podium to write on the blackboard. It provides an outline of knowledge points for students to copy notes for learning, ensuring The storage effect of the teaching podium, the disadvantages of the current technology that need to be optimized are: [0003] Teachers often use chalk to write on the blackboard, and the chalk tips are often piled up on the blackboard grooves or podium tables, which require students to clean them regularly. For developing students, it is easy to inhale chalk dust, causing micro-infection of the respiratory tract and affecting the body. Functional, but the chalk tip is hard, it is easy t...
