Portable multifunctional teaching instrument

Abstract

The invention discloses a portable multifunctional teaching instrument. The portable multifunctional teaching instrument comprises a first bottom plate and a second bottom plate, wherein the top surface edges of the first bottom plate and the second bottom plate are articulated with each other; the bottom surface of the first bottom plate is connected with a first support seat; the top of the first support seat is connected with a spring dynamometer; one end away from the second bottom plate of the spring dynamometer is movably connected with a first connection rope; the other end of the firstconnection rope is connected with a tension sensor; one side of the tension sensor is connected with a support post located on the first bottom plate; the top end of the support post is connected with a display; one end close to the second bottom plate of the spring dynamometer is movably connected with a second connection rope. The portable multifunctional teaching instrument is reasonable in structure and convenient to use; a variety of experiments can be simultaneously recognized and verified; the creative thinking and the imagining abilities of the students can be stimulated; the interestingness of the experiments of the students is improved; the teaching effect is improved; meanwhile, the experiment device is relatively convenient to assemble and disassemble and is convenient to store and carry.

Description

technical field [0001] The invention relates to the technical field of teaching instruments, in particular to a portable multifunctional teaching instrument. Background technique [0002] In middle school physics course teaching, many experiments on mechanics and electromagnetism will be involved. For example, a energized coil can generate a magnetic field, and the magnitude of the magnetic field is related to the magnitude of the current passing through the coil; The magnitude of the force is related to the magnitude and direction of the magnetic field; for example, the elongation of a spring within a certain range is proportional to the magnitude of the tension, etc. These experiments generally have corresponding experimental devices for verification, but only a simple conceptual understanding, The relationship between various physical quantities cannot be verified intuitively through data. At the same time, the experiments are relatively independent and lack of correlatio...

Problems solved by technology

[0002] In middle school physics course teaching, many experiments about mechanics and electromagnetism will be involved. For example, a energized coil can generate a magnetic field, and the magnitude of the magnetic field is related to the magnitude of the current passing through the coil; The magnitude of the force is related to the magnitude and direction of the magnetic field; for example, the elongation of a spring within a certain range is proportional to the magnitude of the tension, etc. These experiments generally have corresponding experimental devices for verification, but only a simple conceptual understanding, The relationship between various physical quantities cannot be verified intuitively through data. At the same time, the experiments are relatively independent and lack of correlation. It cannot stimulate students' creative thinking and imagination well, and cannot make students understand the experiment accurately and quickly. and the existing experimental devices are generally multiple independent parts, but in classroom teaching, experimental demonstrations are required, or students operate in person, and the large number of experimental devices is inconvenient to carry and carry, which affects the quality of experimental teaching
