Physical experimental apparatus box and exploration physical experimental paradigm

Abstract

The invention discloses a physical experimental apparatus box, wherein a box cover is provided with two through holes matched with mounting bolts of a lever support, one side of the reverse side of the box cover is provided with a bind hole, and the middle part of the reverse side of the box cover is provided with two raised-strip guide rails in parallel; the inner cavity of a box body is provided with a bracket which is provided with a measuring cylinder, a spring dynamometer and a flask respectively in clamping way, the lever support, a lever cross beam and a flask support are arranged beside the measuring cylinder, and the inner cavity of the measuring cylinder is provided with a thermometer pulley support and a laser pen; a counter balance is arranged beside the spring dynamometer, and a mechanical part case, an optical small-part case and an optical bid-part case are arranged at two sides of the tip of the counter balance; and the optical small-part case is internally provided with a fixed pulley, a movable pulley and hook weights, and the optical big-part case is internally provided with an optical socket, a small pore plate, a white screen, a convex lens, a plane mirror, plane glass and a circular dial scale. The physical experimental apparatus box disclosed by the invention has the advantages of small size, multiple purposes, portability and low cost, can be taken by every student who participates in a physical experiment, and can meet the requirements for making experiments independently by the students.

Description

technical field [0001] The invention relates to an experimental instrument. In particular, the utility model relates to an experimental instrument box and an example of exploring a physical experiment. Background technique [0002] Physics is an experimental science, which requires students to do a lot of experiments to strengthen their understanding and master the knowledge they have learned. Doing experiments by yourself can help you understand the concepts of physics and master the laws of physics. However, in the current physics teaching process, due to the small number of laboratories and the large number of students in many schools, they only do some demonstration experiments, which cannot satisfy students to do experiments by themselves. requirements. Contents of the invention [0003] The object of the present invention is to provide a small, smart, multi-purpose, portable physical experiment instrument box and a physical experiment paradigm. [0004] The techni...
