Abstract
Disclosed in the utility model is a dual-circular truncated cone drawing teaching model comprising an inner circular truncated cone, an outer circular truncated cone, an upper helicoid and a base seat. The inner circular truncated cone and the outer circular truncated cone are inverted coaxially; and the inner circular truncated cone is higher than the outer circular truncated cone. The upper helicoids and a lower helicoid are processed at the outer circular truncated cone; and the depths of the upper helicoid and the lower helicoid extend to the surface of the inner circular truncated cone, thereby forming an approximate torch shape. And the base seat is arranged at the bottoms of the inner circular truncated cone and the outer circular truncated cone to provide supporting. The provided teaching model has the following effects: the model is formed based on processing and improvement of a circular truncated cone base body model; both the circular truncated cone and the helical line can be demonstrated; the model is an approximate torch shape; and the teaching effect is good.
Description
Technical field
The utility model relates to a kind of teaching mode, and more specifically, it relates to a kind of two round platform drawing teaching model.
Background technology
At present, round platform model generally can only be shown its pattern, explanation basic construction method general knowledge, and practical application is less, lacks intention, greatly arouse the interest in study.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, easy to use, two round platform drawing teaching models that teaching efficiency is good.
This pair of round platform drawing teaching model, comprises interior round platform, outer round platform, upper helicoid and pedestal; Interior round platform and outer round platform are coaxially inverted, and interior round platform is higher than outer round platform; On round platform, process outside helicoid and lower helicoid, upper helicoid and the lower helicoid degree of depth, to interior round platform surface, are similar to torch-like; Pedestal is located at interior round platform and outer round platform bottommost provides support.
The beneficial effects of the utility model are: by process improvement on round platform element body model basis, round platform can be demonstrated, helix can be demonstrated again, and likeness in form torch, teaching efficiency is good.
Brief description of the drawings
Fig. 1 is the main TV structure figure of the utility model;
Fig. 2 is the utility model plan structure figure;
Reference numeral: interior round platform 1, outer round platform 2, upper helicoid 3, lower helicoid 4, pedestal 5.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
Referring to shown in Fig. 1 to Fig. 2, this pair of round platform drawing teaching model, comprises interior round platform 1, outer round platform 2, upper helicoid 3 and pedestal 5; Interior round platform 1 is coaxially inverted with outer round platform 2, and interior round platform 1 is higher than outer round platform 2; On round platform 2, process outside helicoid 3 and lower helicoid 4, upper helicoid 3 and lower helicoid 4 degree of depth, to interior round platform 1 surface, are similar to torch-like; Pedestal 5 is located at interior round platform 1 and outer round platform 2 bottommosts provide support.Can be used as the use of round platform application case or creation case teaching.
