Problems solved by technology

[0003] However, there are still many technical defects in the actual operation of the physical experiment platform. First of all, from the teacher's point of view, students stand near the experiment platform to watch the teacher's operation. On the one hand, it is not easy for the students behind to see clearly; It is inconvenient for students to adjust the position to watch when the teacher operates in different positions; secondly, from the perspective of students, students need to prepare different experimental instruments according to different physical experiments in their own laboratories. It needs to be temporarily resupplied due to the lack of it, which will affect the normal progress of the experiment

Embodiment 1

[0034] Example 1: In actual use, the whole is moved by the moving wheel 2 at the bottom of the test bench body 1 and the whole is fixed by the foot brake on the moving wheel 2 . When the teacher is teaching the experimental demonstration, he pulls the limit pin 1102 and stretches the spring 1105 through the fixing block 1104 on the outside of the handle 1101 in advance, so that the limit pin 1102 is detached from the limit hole 1103 on the outside of the lifting frame 9. The rotating shaft 1001 in the lifting frame 6 is driven by the handle 1101 to rotate, and the threads in the opposite directions on the outside of the rotating shaft 1001 drive the two sets of movable blocks 1002. Since the upper connecting rods 1004 of the two sets of movable blocks 1002 and the opening of the lifting frame 6 are limited and slid, at this time, the two sets of movable blocks 1002 The movable block 1002 slides relatively and adjusts the angle of the connecting rod 1004 . The outside of the con...

Embodiment 2

[0041] Embodiment 2: When teaching different experiments, the teacher can prepare different experimental instruments in advance, and place the experimental instruments on the placement plate 12 in the functional cavity 4, and simultaneously turn on the camera 13 through the switch group 502, and the camera 13 Through the built-in processor of the component cavity 3, the display screen 501 is electrically connected to display the photographed picture, and the threaded rod 402 is driven to rotate by the rotating sleeve 403. Therefore, the height of the placing plate 12 is adjusted, so that the instruments on the upper end of the placing plate 12 can be photographed by the photographing camera 13 . After the camera 13 has photographed all the instruments, the teacher can use the computer 7 to cooperate with the key-in device 8 to store the photos and name the experiment names. When students conduct experiments by themselves, they can place the pre-prepared instruments on the place...

Abstract

A physical experiment table disclosed by the present invention comprises an experiment table body and an operation table, the upper end of the experiment table body is fixedly provided with a computer and a typing device, an inner cavity of the experiment table body is provided with an element cavity and a function cavity, a processor is arranged in the element cavity, the outer side surface of the element cavity is provided with a control panel, and a placement plate is movably arranged in the function cavity. A camera is fixedly arranged at the top of the inner cavity of the functional cavity, a lifting frame is further fixedly arranged at the upper end of the experiment table body, and an opening communicated with the inner cavity is formed in the upper end of the lifting frame. The height of the experiment operation table can be rapidly adjusted and fixed, a teacher can conveniently and better display teaching to students, the relative stability of the operation table during operation of the teacher is guaranteed, and in addition, different experiment instruments can be photographed and filed; before subsequent experiments, the instruments prepared by the students can be photographed again and compared with the corresponding archived photos of the experimental instruments, whether the instruments are missed or not is checked, and normal and smooth proceeding of the subsequent physical experiments is guaranteed.

Description

technical field [0001] The present invention relates to the field of test benches, and more particularly, to a physical test bench. Background technique [0002] With the rapid development of society and economy, physics is a discipline that studies the most general laws of matter motion and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms of motion of all matter ranging from the universe to the smallest elementary particles. and laws, so it has become the research basis of other natural science disciplines. Its theoretical structure fully uses mathematics as its working language, and uses experiments as the only standard to test the correctness of the theory. It is the most sophisticated natural science discipline today, and requires a lot of experimental equipment and equipment in the process of physical experiments. Raw materials, physics laboratory is a place for physics teaching and research, including ph...
