Portable practical training experimental instrument

Abstract

The invention relates to a portable practical training experiment instrument which comprises a first box body and a second box body which are hinged, the interior of the first box body is divided intoa first containing cavity and a first mounting cavity which are arranged up and down through a first partition plate, and the interior of the second box body is also divided into a second containingcavity and a second mounting cavity which are arranged up and down through a second partition plate. At least two first supporting rods and a first driving piece for driving the first supporting rodsto do telescopic motion are arranged in the first mounting cavity, at least two second supporting rods and a second driving piece for driving the second supporting rods to do telescopic motion are arranged in the second mounting cavity, and four third supporting rods are arranged on the inner side wall of the second containing cavity. By adopting the technical scheme, the portable practical training experimental instrument provided by the invention is convenient to carry and store, can be moved at any time, is convenient for students to see experimental demonstration clearly, and has a good teaching effect.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a portable experimental instrument for practical training. Background technique [0002] Physics is a natural science that studies the most basic structure of the material world, the most common interaction, the most general law of motion, and the experimental methods and thinking methods used; many concepts, laws, and laws in physics textbooks are developed through experiments. Introduced, derived and verified, such as the law of inertia, gravity experiments and buoyancy experiments, etc. [0003] Generally, the physics teacher brings the required physical experiment equipment to the classroom for teaching, but in the case of too many equipment, it is inconvenient to carry, time-consuming and labor-intensive. And when doing experiments, because the podium is low, it is difficult for the students in the back row to see clearly. It is not realistic to move the po...

AI Technical Summary

Problems solved by technology

Although this utility model is equipped with universal self-locking wheels, it is convenient for the movement of the experiment platform, and solves the problem that the platform in the prior art cannot be moved to the middle of the classroom for experiments, but it has not completely solved the problem that the experimental equipment is easy to carry. Easy to bulky, inconvenient to carry
