Specimen exhibition device for biological teaching

Abstract

The invention discloses a specimen exhibition device for biological teaching. The device comprises a box body, wherein a limiting groove is formed in the top of the box body; a motor is mounted in the limiting groove; an output end of the motor is arranged upwards; a rotating shaft is mounted at the output end of the motor; a rotating disk is fixed at the upper end of the rotating shaft and adopts a round structure; six specimen boxes are circumferentially arranged at the top of the rotating disk; universal wheels are arranged at the bottom of the box body; a power plug and a power switch are arranged at the upper part of the box body; a digital camera is fixed on a camera bearing seat; a camera lens end of the digital camera is arranged downwards and is located right above the specimen boxes; a liquid crystal display is arranged in the middle of one side surface of the box body. The rotating disk is rotated by the motor conveniently in an effort-saving manner, besides, the efficiency is high, and students can see specimens clearly, learn fast and understand the specimens better.

Description

technical field [0001] The invention relates to the technical field of specimen display devices for biology teaching, in particular to a specimen display device for biology teaching. Background technique [0002] At present, in the process of biology teaching in schools, in order to improve the teaching quality and enable students to better understand and master the biological knowledge they have learned, teachers generally use the combination of textbook theoretical knowledge and biological specimens to explain. In order to facilitate teaching and students to observe, the utensils used to store these specimens are generally glassware. Since the specimens need to be well preserved, these biological specimens are generally soaked in disinfectant, so the glassware is generally sealed so that the specimens in the vessel cannot be rotated. , Students’ observation of specimens is not comprehensive during classroom teaching, and teachers need to turn glassware by hand, which not o...

AI Technical Summary

Problems solved by technology

In order to facilitate teaching and students to observe, the utensils used to store these specimens are generally glassware. Since the specimens need to be well preserved, these biological specimens are generally soaked in disinfectant, so the glassware is generally sealed so that the specimens in the vessel cannot be rotated. , students’ observation of specimens is not comprehensive during classroom teaching, and teachers need to turn glassware by hand, which not only consumes time and effort, reduces teaching efficiency, but also easily attaches dirt such as handprints to glassware, affecting students’ observation effect

In addition, sometimes a variety of biological specimens are needed in the classroom, and these specimens are compared and observed to strengthen the memory of the students. Turning multiple specimens in this way will easily make the teacher confused and affect the teaching efficiency. Therefore, the present invention proposes a biological Specimen display device for teaching, improving the deficiencies in the prior art
