Teacher demonstration platform for physics laboratory

Abstract

The invention discloses a teacher demonstration platform for a physics laboratory. The teacher demonstration platform comprises a platform plate, wherein a groove is formed in the left side of the upper end of the platform plate; an instrument gauge is fixedly connected with the upper end of the platform plate; the left side of the lower end of the platform plate is fixedly connected with an equipment cabinet; a fixed plate is arranged at the inner side of the equipment cabinet; a retractable air cylinder is arranged at the upper end of the fixed plate; a connecting plate is fixedly connectedwith the end part of a retractable shaft of the retractable air cylinder; the upper end of the connecting plate is fixedly connected with an angle motor; a hoisting platform is fixedly connected withthe end part of an output shaft of the angle motor in a manner of penetrating through the platform plate; an instrument cabinet is arranged at the right side of the lower end of the platform plate. According to the teacher demonstration platform for the physics laboratory, disclosed by the invention, students can more directly observe an experiment process in a teaching process of a teacher; the teacher demonstration platform has various functions, the understanding of the students on experiments is deepened and the teaching quality and effect are easy to improve.

Description

technical field [0001] The invention belongs to the technical field of physics teaching tools, and in particular relates to a demonstration table for teachers in a physics laboratory. Background technique [0002] Physics experiments are generally carried out in specific physics laboratories, and there are specific experimental classes. At present, many experimental classes require teachers to conduct experimental teaching demonstrations, that is, teachers explain the use of equipment and demonstrate experimental procedures to group students, especially the precautions for operation, so as not to Students need a teacher's demo table if they mishandle the instrument, damage the instrument, or injure themselves. The teacher's demonstration table in the physics laboratory is a tool that is convenient for the teacher to describe the physical experiment. However, the teacher's demonstration table in the prior art has a simple structure and a single function, and it is difficult t...

The teacher's demonstration table in the physics laboratory is a tool that is convenient for the teacher to describe the physical experiment. However, the teacher's demonstration table in the prior art has a simple structure and a single function, and it is difficult to meet the needs of the teacher. For example, when students come to the laboratory to do experiments, the teacher demonstrates If th
