Teaching demonstration mechanism capable of adjusting falling mode

Abstract

The invention relates to a teaching demonstration mechanism capable of adjusting a falling mode, the mechanism comprises a support seat, a discharge positioning mechanism and a falling seat are arranged on the support seat, a side face of the falling seat is provided with a falling cylinder, a cylindrical heavy block is arranged in the falling cylinder, an upper part of the heavy block is connected with a drawstring, an upper end of the drawstring penetrates beyond a falling adjustment cooperation opening arranged on an upper part of the falling cylinder, a guiding pulley wheel passes throughan upper part of the falling seat and is provided with a downward end head after penetrating beyond the falling adjustment cooperation opening, the guiding pulley wheel is connected with a handle, thefalling adjustment cooperation opening is larger than the heavy block, the upper part of the falling seat is provided with a falling adjustment slot, a bottom part of the falling adjustment slot is provided with a vertical running falling adjustment cylinder, a falling adjustment block is connected above the falling adjustment cylinder, and the guide pulley wheel is arranged on the falling adjustment block; in the teaching demonstration mechanism, the guide pulley wheel is arranged on the elevating falling adjustment block, boundaries of two simulation modes can be separated clearly via the falling adjustment block, and phenomena that injuries of experiencers are caused due to inaccurate pulling amplitude while a pull rope is controlled manually can be eliminated.

Description

Technical field [0001] The invention relates to the field of teaching equipment, in particular to a teaching demonstration mechanism capable of adjusting the smashing mode. Background technique [0002] With the advancement of mechanization, there are more and more students in the mechanical field. Because factories have a variety of uncertain risk factors, most schools will teach students safely. In order to improve the effectiveness of teaching, it is best to experience safety equipment by yourself Therefore, some teaching demonstration equipment has appeared. Among them, the demonstration organization of factory leather shoes is one of the most common teaching demonstration organizations. The toe of factory leather shoes is hard, which can play a good protective effect against some heavy pieces. Therefore, it is necessary for students to personally experience the role of factory leather shoes through such equipment, so that students can abide by factory rules in the follow-up ...

[0002] With the advancement of mechanization, the number of students in the mechanical field is increasing. Due to the various uncertain risk factors in the factory, most schools will teach students about safety. In order to improve the teaching effect, it is best to experience safety equipment by yourself. Therefore, there have been some teaching and demonstration equipment, among which the demonstration mechanism of factory leather shoes is one of the most common teaching and demonstration mechanisms. The toe of factory leather shoes is hard, which can play a good protective effect against the falling of some heavy blocks. Therefore, it is necessary to allow students to experience the function of factory leather shoes in person through such equipment, so that students can abide by the factory rules in the follow-up work. Most of the existing teaching and demonstration institutions for the function of factory leather shoes The feeding positioning mechanism and the falling mechanism, the falling mechanism uses a pull rope and a heavy block to realize the falling simulation. In order to better simulate the falling, two modes of simulation are generally carried out. The first is to let students experience the factory leather shoes It has a good protective effect. The second simulation is to let students feel that even if the factory leather shoes have a good protective effect, their protection is limited. Paying attention to safety is the most important thing. The drop heights of the two modes are different. , it is necessary to manually control the pulling range of the pull rope, and it is easy to exceed the resistance limit of the factory leather shoes and cause the experiencer to be injured
