Embodiment Construction

[0025] A combined drawing teaching model, including a bottom block 1 and a top block 2, the bottom block 1 is composed of two sub-blocks 3, the surface of each sub-block 3 is provided with a semicircular annular groove 4, and the two sub-blocks 3 Docking, so that two semicircular annular grooves 4 form a complete circular annular groove, the end face of the top block 2 has a circular annular protrusion 5, and the circular annular protrusion 5 of the top block is connected to the bottom plate The circular annular groove movable connection. (See figure 1 , figure 2 )

[0026] Preferably, a central column 6 is provided between the base plate 1 and the top block 2, the lower surface of the central column is provided with a circular annular protrusion 7, and the upper surface of the central column is provided with a circular annular groove 8. The circular ring-shaped projection 7 of the column is movably connected with the circular ring-shaped groove of the base plate, and the ...

Abstract

This invention discloses a combined cartography teaching model, which includes the backing sheet and top block. The above-mentioned backing sheet is composed of two branch blocks, whose surfaces have semicircular flutes. The two branch blocks are joined together to make the semicircular flutes form an intact circular flutes. An end face of the abovementioned top block has a circular cam, which can form movable connection with the circular flute. There can be a vertical shaft between the backing sheet and the top block. The invention can use the backing block and the top block as the basic blocks or the backing block, vertical shaft and top block as the basic blocks to assemble different whole models to be used in cartography courses. During the assembling, the user not only can observe it by compare, but also is encouraged to create. It provides material conditions to the students.

Description

technical field [0001] The invention relates to a teaching model, in particular to a combined teaching model. Background technique [0002] At present, the physical models used in drawing teaching are basically divided into two forms. One is the integral model, which is made of each model as a single body and cannot be disassembled. The other is a single decomposed model. This model is based on the overall model. According to certain teaching needs, the overall model is decomposed into several blocks. The decomposed blocks can show the parts that need to be emphasized in the model. When assembled, it becomes a overall. Although this model can be decomposed and used, the decomposed blocks are generally attached to the basic model, and there is no universality and interchangeability with other models. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies in the prior art, and provide a kind of combined drawing teaching model for st...
