Problems solved by technology

[0002] At present, when teachers teach the principle of mechanical self-locking, they often use simple diagrams. Although they can solve some problems, the effect is not ideal due to the simplicity of diagrams and the narrow scope involved.
Without a perceptual understanding, it is difficult for students to deeply understand the principle of self-locking, which also increases the difficulty of teaching for teachers

Abstract

The invention discloses a teaching tool for the dynamic demonstration of a mechanical self-locking phenomenon, and the tool comprises a cube box body, a jaw crusher self-locking device, a presser self-locking device, a cam push rod, and a friction circle self-locking device. Only if a pressure rod, a push rod, a screw rod and a friction strip need to be adjusted, can the parameters, correlated with self-locking, in all device be changed. The tool has complete devices, is good in enlightening effect, is exquisite in appearance, is convenient to operate and carry, and is high in market application value.

Description

technical field [0001] The invention relates to a teaching appliance, in particular to a teaching appliance for dynamically demonstrating the self-locking phenomenon. Background technique [0002] At present, when teachers teach the principle of mechanical self-locking, they often use simple diagrams. Although some problems can be solved, the effect is not ideal due to the simplicity of diagrams and the narrow scope involved. Without a perceptual understanding, it is difficult for students to deeply understand the principle of self-locking, which also increases the difficulty of teaching. Contents of the invention [0003] The problem to be solved by the present invention is to design a teaching tool that integrates a variety of typical self-locking devices, and the parameters of each device are adjustable, and can realize dynamic demonstration. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions. [000...
