Multi-angle teaching exhibition mechanism for biological sample exhibition

Abstract

The invention relates to the technical field of biology, and discloses a multi-angle teaching exhibition mechanism for biological sample exhibition, the multi-angle teaching exhibition mechanism comprises a shell, the top of the shell is fixedly connected with an exhibition frame; according to the principle of a photoresistor, when a biological sample is placed on the placing base, closing of a placing opening and transposition operation are automatically triggered, linkage between structures is improved, operation is convenient and fast, the automation degree is high, the placing opening of the display frame is automatically closed, the biological sample is in a sealed environment, the possibility that the biological sample is damaged by external factors in the display process is reduced, smooth display operation is facilitated, two hands are liberated, complicated operation is avoided, the intelligent degree is high, through the combined action of a placement seat, a supporting rod, a rotating frame, a first gear, an I-shaped rod and an arc strip, the biological sample intermittently rotates by 90 degrees in the display process, an observer can conveniently observe different surfaces of the biological sample at different angles, so that the comprehensive display effect is achieved, and the observation effect is better.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a multi-angle teaching and exhibition mechanism for displaying biological samples. Background technique [0002] In order to realize the popularization of biological knowledge, biology has become one of the main teaching subjects, which is a science that studies the structure, function, occurrence and development of biology. In the process of biology teaching, in order to facilitate learners to understand more intuitively, the method of observing the display of biological samples will be used for learning. Most of the current biological samples are displayed directly, which is very easy to collide with the biological samples, increasing the probability of damage, which is not conducive to the display operation. At the same time, due to the static placement of the biological samples, the viewer's viewing angle is single, and it is impossible to observe the biological samples comprehe...

AI Technical Summary

Problems solved by technology

Most of the current biological samples are displayed directly when they are displayed, which is very prone to collision with biological samples, increasing the probability of damage, which is not conducive to the display operation

At the same time, due to the static placement of the biological samples, this makes the viewer's viewing angle single, unable to conduct a comprehensive observation of the biological samples, resulting in poor display effects, and a one-sided understanding of the biological samples, which affects the quality of teaching

However, the existing display devices have a relatively low degree of automation and a relatively low degree of manual intervention, and are time-consuming and laborious to use, which cannot meet the actual use conditions.
