The structure and composition of the molecular structure teaching model
Molecular structure is a molecular structure teaching model, including a plurality of substrates, and a plurality of atomic models are embedded on the substrates; chemical bonds are connected between the atomic models, the chemical bonds are embedded on the substrate, and the chemical bonds It includes a rotating key and a fixed key, the rotating keys are all arranged on the base plate obliquely, and the fixed keys are all vertically set on the base plate. In the present invention, by setting a plurality of base plates, the atomic models embedded on the base plate are respectively fixed on the base plate. The bond and the rotation bond are fixed, the atoms fixed on the substrate are in the same plane, and the connection angle and orientation between the atomic models will not be arbitrarily changed when the overall substrate is rotated, so as to avoid the atomic angle after rotation showing that the actual atom does not change. The positional relationship of the atomic models connected by fixed bonds is relatively fixed, and the atomic models connected by rotational bonds can be rotated according to the actual situation, which can simulate the dynamic changes of the natural conformation of molecules.
Molecular structure model, including molecular ball, connecting hole, ball head shaft, connecting rod, support column, storage compartment, rotating shaft, base, USB jack, video player, copper sheet, threaded structure and colorful lights; the internal design of the base There is a storage compartment, the top of the base is provided with a support column and a USB jack, the back of the base is provided with a video player, the middle of the support column is provided with a rotating shaft, and the top of the support column is movably connected with the molecular ball through the connection hole, adjacent to the The two molecular balls are movably connected by connecting rods, the middle of the connecting rods are provided with ball head shafts, both ends of the connecting rods and the connecting holes are provided with copper sheets, and the surfaces of the copper sheets are provided with threaded structures. There are many colored lights in the molecular ball.
The molecular structure model for teaching solves the problems of poor molecular structure display effect and inconvenient connection and disassembly in the prior art, so that the model display effect is better, convenient and practical.
