Description
Technical field
The utility model belongs to economics education equipment technical field, and in particular to the demonstration mould that a kind of macroeconomy increases
Type.
Background technology
The growth of national economy can receive the influence of outlet, consumption, investment and policy adjustment etc. many factors, close
In the teaching process of growth of the national economic, process excessively complexity often be present causes student's indigestion, or causes student
The problems such as lacking learning interest.At present, can still be taught through lively activities without one kind, the demonstration growth of the national economic of simple, intuitive
Journey, and the teaching aid of the influence of each factor.
Utility model content
Can be by growth of the national economic simple, intuitive in order to solve to lack in the prior art one kind, and student can be increased
The Teaching of Economics apparatus of learning interest, the utility model provide a kind of macroeconomy and increase demonstrating model, the skill taken
Art scheme is as follows：
A kind of macroeconomy increases demonstrating model, and the demonstrating model is by casing, increases post, multiple power-assisted casees 3, connection helps
Power case and the pipeline composition for increasing post；
The growth post whole or local structure are in the inside of casing；
Gaseous medium containing different colours inside the multiple power-assisted case；
There is flow control valve on the pipeline；
Described pipeline one end connects with power-assisted case, and the other end connects with positioned at the contribution bag increased inside post；
The contribution bag from the connection of different power-assisted casees is provided with inside the growth post；Increase and clear, colorless liquid Jie is provided with post
Matter, buoy is provided with colorless liquid top of media；Contributed bag is respectively positioned on below the liquid level of colorless liquid medium.
Preferably, it is different with residing horizontal level from the contribution of different power-assisted casees connection.
Preferably, the color of different contribution bags is different.
Preferably, described contribution bag is by circular hard bottom and the flexible extension group being connected with circular hard bottom
Into the bottom of the flexible extension is provided with the interface with pipeline communication.
Preferably, the pipeline of each power-assisted case is provided with branch pipe, and the end of branch pipe is provided with damping box.
It is highly preferred that the branch pipe is provided with the valve of control pipeline flow area, in order to control gas in power-assisted case
Number of dropouts, so as to characterize the negative factor of the influence active factor.
Relative to prior art, the beneficial effects of the utility model are：By increase in post it is transparent readily volume come generation
The population size of table national economy.The speed risen by dark buoy in post is increased is fast to represent the growth of national economy
Degree.
Each favorable factor that can promote growth of the national economic, or major contribution factor are represented by power-assisted case.
Power-assisted case is connected by pipeline with positioned at the contribution bag increased inside post, can pass through the gas of the injection different colours into contribution bag
To characterize the contribution rate of the national economy of different factors.
Flow control valve is equipped with all pipelines, the supply gas flow velocity in power-assisted case can be controlled, from
And the speed of contribution bag elongation can be controlled, to characterize contribution rate of the national economy difference contribution factor to economic growth rate, with
And the vigor increased.
Brief description of the drawings
Fig. 1 is the positive structure diagram of demonstrating model in a kind of optimal technical scheme of the utility model；
Fig. 2 be Fig. 1 in increase post along A to cross section structure diagram.
In figure：1st, casing；2nd, post is increased；3rd, power-assisted case；4th, pipeline；5th, flow control valve；6th, bag is contributed；7th, colorless liquid
Medium；8th, buoy.
Embodiment
Below in conjunction with accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by.Obviously, described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
Wherein, Fig. 1 is the positive structure diagram of demonstrating model in a kind of optimal technical scheme of the utility model.Fig. 2 is
In Fig. 1 increase post along A to cross section structure diagram.It was found from from Fig. 1 and Fig. 2, the demonstrating model is pacified by casing 1, part
Mounted in the growth post 2 of casing 1, and power-assisted case 3, pipeline 4 forms.Wherein, it is cylindrical column to increase post 2, inside injection nothing
Color liquid medium 7, such as pure water.Meanwhile the contribution bag 6 connected with pipeline 4 is additionally provided with growth post 2.Helped from different
The bottom for the contribution bag 6 that power case 3 connects by pipeline 4 is in different horizontal levels.The bottom for contributing bag 6 is hard circular base
Portion, top are the bag body of flexible, distensible.Meanwhile dark buoy 8 is placed at the top of colorless liquid medium.
In this preferred scheme, 6 power-assisted casees 3 for being fixedly installed to the bottom of casing 1 are provided with casing 1 altogether.Meanwhile every
Flow control valve 5 is equipped with the individual pipeline 4 being connected with power-assisted case 3, in order to be controlled to output end flow in power-assisted case 3
System.
This demonstrating model in use, can be to increase height of the colorless liquid medium 7 on post 7 is increased in post 2
Degree represents the economic total volume of country.And different power-assisted casees 3 can be as the main active factor for promoting national economy to increase.Pass through
Power-assisted case 3 injects gas to post 2 is increased, and makes the volume of contribution 6 increase, so that buoy 8 constantly raises.The teacher of explanation and listen
Class can assess growth rate by the above-mentioned speed of buoy 8.Meanwhile the contribution bag 6 of different colours can represent different above-mentioned products
The contribution of pole factor.This demonstrating model has simple in construction, lively, directly perceived, interesting strong, can effectively improve student
Efficiency and teacher operating efficiency.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every that there is same as the present application or phase
Approximate technical scheme, all falls within the scope of protection of the utility model.
