Cell mitosis dynamic simulation teaching aid

Abstract

The invention provides a cell mitosis dynamic simulation assembly, relates to the technical field of biological teaching equipment, and solves the technical problem that a teaching tool in the prior art influences a teaching effect due to the fact that a mitosis simulation process is not comprehensive enough and cannot be dynamically displayed. The assembly comprises a control device, a transmission device, a cell membrane assembly, a spindle body assembly and a dyeing monomer assembly, the cell membrane assembly comprises two arc-shaped pieces which are oppositely arranged and are in sliding fit, and part of sections of the two arc-shaped pieces are overlapped to form a circular mother cell membrane assembly in a surrounding mode; the spindle body assembly and the dyeing monomer assembly are both arranged in the circular maternal cell membrane assembly, the transmission device is in transmission connection with the spindle body assembly, and the spindle body assembly can abut against the corresponding arc-shaped piece and push the arc-shaped piece to slide; the two arc-shaped pieces can be separated from each other and form two independent sub-cell membrane assemblies; the simulation process is comprehensive, and dynamic display can be realized.

Description

technical field [0001] The invention relates to the technical field of biological teaching equipment, in particular to a dynamic simulation teaching aid for cell mitosis. Background technique [0002] Mitosis, also known as indirect division, refers to the process of eukaryotic cell division to produce somatic cells. It is an important knowledge point in biology teaching courses. Cell mitosis teaching aids are widely used in the teaching process of cell mitosis as a teaching tool. However, the existing cell mitosis teaching aids can only simulate the division process of chromosomes in the process of cell mitosis, or use multiple sets of teaching aids in different states to simulate the states of cells in different stages of cell mitosis. These mitosis teaching aids are not only not comprehensive enough to simulate the process , and it is impossible to dynamically display the splitting process intuitively, and there are many disadvantages, which greatly affect the teaching ef...

Problems solved by technology

[0003] The purpose of the present invention is to provide a dynamic simulation teaching aid for cell mitosis, to solve the technical problem that the existing teaching tools in the prior art are not comprehensive enough to simulate mitosis and cannot be dynamically displayed, which affects the teaching effect; many technologies provided by the present invention The many technical effects that can be produced by the optimal technical scheme in the scheme (arc-shaped chute and slide block with shape fit are arranged on the arc-shaped part, which is convenient for the two arc-shaped parts to slide relative to each other; the housing includes a mounting cavity for transmission The housing includes a display cavity, which can not only accommodate the chromatid assembly, the spindle assembly and the cell membrane assembly, but also directly display their dynamic changes; each chromatid assembly includes multiple chromatid units The component is used to simulate the dynamic changes of multiple chromosomes; the sliding track and the sliding part cooperate with each other to effectively limit the sliding track of the chromatid unit unit during the movement; the chromatid unit unit includes the first connecting rod and the second connecting rod And connecting axis, two chromatid unit units cooperate with each other to simulate chromosomes; guide posts and guide channels cooperate with each other, chromatid unit units coincide with each other when they are in the initial position, and can simulate chromosomes with the sliding of chromatid unit units The process of copying and separating; the spindle assembly includes a traction piece and a connecting rod, the traction piece is used to simulate the spindle body, and the traction piece can drive the corresponding chromatid unit to slide through the connecting rod; the transmission device includes an input device, a synchronization device and The output device, under the control of the operating device, can drive the two spindle assemblies to move synchronously and reversely on the same straight line; the transmission device also includes a tensioning device, which is used to tighten the transmission belt to ensure that the transmission The transmission effect of the device, etc.) See below for details
