Abstract

The invention relates to the technical field of education, and discloses a physical mechanics demonstration device which solves the problems that an existing physical mechanics demonstration device is inconvenient to move, so that the portability is poor, meanwhile, the height is fixed, the height cannot be adjusted according to operators with different heights, and the practicability is not high. A containing groove is formed in the demonstration operation table, a containing cabinet is inserted into the containing groove in a penetrating mode, supporting columns are symmetrically arranged on the two sides of the bottom end of the demonstration operation table, every two adjacent supporting columns are connected through a supporting plate, two universal wheels are symmetrically arranged at the bottom end of each supporting column, and a mounting box is arranged at the bottom end of each supporting plate. A lifting rod is arranged below the mounting box and is of a U-shaped structure; through the design of the height adjusting mechanism, the height of the demonstration operation table can be conveniently adjusted according to the height of an operator, the operator can conveniently carry out force demonstration work, and meanwhile the work fatigue degree of the operator is reduced.

Description

technical field [0001] The invention belongs to the field of education technology, in particular to a physical mechanics demonstration device. Background technique [0002] The knowledge of energy conversion is described in physics textbooks. An elevated object has potential energy, and a moving object has kinetic energy. They can be transformed into each other, and energy can be converted from one form of energy to another form of energy. [0003] However, the existing physical mechanics demonstration device is inconvenient to move, resulting in poor portability, and at the same time, the height is fixed, and the height cannot be adjusted according to operators of different heights, resulting in low practicability. Contents of the invention [0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a physical and mechanical demonstration device, which effectively solves the problem that the existing physical ...
