Description
Technical field
The utility model relates to the technical field of geography teaching appliance, is specially a kind of multi-functional geographical measurement and positioning chi.
Background technology
Geography course is one of our important course that just must learn from junior middle school.Studying the geography has following benefit: one, increase experience, enrich information, after studying the geography geography, just can " stay indoors and know all over the world ".This can form the knowledge hierarchy that you are familiar with the world, becomes a pundit, energy and others have the people of talk capital.Two, differentiate things orientation, after have learned geography, we will know that Somalia is in African northeast, quite poor, all become pirate after can not living, and Red sea when near it being,, so there is a lot of freighter, just there is the possibility of abduction in important international freight forwarding course line.Three, wilderness lore is indispensable, and as having a lot about the introduction of nature things in geography, such as the Big Dipper points to, and in desert, water source exists, and how escape from danger occurs for natural calamity such as earthquake, mud-rock flow, typhoon etc.Four, knowledge of natural environment circle, in fact geographical dead very closely with contacts such as biology, aviation, geology.As arboreal growth rule, geological structure, metagalaxy model, air are formed ... these are all the most basic modes in the understanding world.After having learned geography, you have just known, what is it about present greenhouse effects, what is it about low-carbon economy, how various natural calamity is formed and show effect, and why colliery gas explosion can occur if mining for coal, why will implement Lunar Probe Project etc.
At present, the geographical teaching ruler purposes of selling on the market is single, can only be used for measurement scale; but geographical teacher, to classmates' upper class hour, gave lessons intuitively to can more unwind, and often can use ruler measurement distance; take measurement of an angle with protractor, also need to distinguish orientation and measurement level.Therefore in teaching process, use ruler in the market, it also needs to carry a large amount of aids, makes troubles to teaching.For the problems referred to above, we have developed that a kind of structure is simple, easy to use, multiple functional, the multi-functional geographical measurement and positioning chi of accurate positioning.
Utility model content
The purpose of this utility model is for above-described problems of the prior art, provides that a kind of structure is simple, easy to use, multiple functional, the multi-functional geographical measurement and positioning chi of accurate positioning.
In order to realize described object, the utility model specifically adopts following technical scheme:
A kind of multi-functional geographical measurement and positioning chi, it comprises ruler body 1, semicircle protractor 2, level meter 3, compass 4, longitude-latitude coordinates 5, fixture 6, handheld component 7, deep-slotted chip breaker 8, cross coordinate 9.It is characterized in that: described ruler body 1 one end is fixedly connected with semicircle protractor 2, top is provided with level meter 3, compass 4, longitude-latitude coordinates 5, handheld component 7, deep-slotted chip breaker 8, and described ruler body 1 another surface relative with handheld component 7 is provided with fixture 6.
Described ruler body 1 is provided with the cross coordinate 9 of a hollow out.
A kind of multi-functional geographical measurement and positioning chi of the utility model, described ruler body 1 one end is fixedly connected with semicircle protractor 2, top is provided with level meter 3, compass 4, longitude-latitude coordinates 5, handheld component 7, deep-slotted chip breaker 8, its structure is simple, multiple functional, accurate positioning, and handheld component 7 facilitate this ruler take, put and be shifted; Another surface that described ruler body 1 is relative with handheld component 7 is provided with fixture 6, and it by fixing for ruler with on blackboard, not easily can be shifted, can not cause picture deviation, improve teaching level in mapping process.
Compared with prior art, the beneficial effects of the utility model are: one, described level meter 3 centering horizontal plane, and compass 4 is made a comment or criticism direction, and the judgement of longitude-latitude coordinates 5 for graticules and the judgement of 2 mutual alignments are multiple functional, easy to use; Two, described ruler body 1 is provided with the cross coordinate 9 of a hollow out, its accurate positioning; Three, another surface that described ruler body 1 is relative with handheld component 7 is provided with fixture 6, and it by fixing for ruler with on blackboard, not easily can be shifted, can not cause picture deviation, improve teaching level in mapping process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: ruler body 1, semicircle protractor 2, level meter 3, compass 4, longitude-latitude coordinates 5, fixture 6, handheld component 7, deep-slotted chip breaker 8, cross coordinate 9.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, structure of the present utility model and beneficial effect thereof are further illustrated.
Embodiment 1
A kind of multi-functional geographical measurement and positioning chi, as shown in Figure 1.It comprises ruler body 1, semicircle protractor 2, level meter 3, compass 4, longitude-latitude coordinates 5, fixture 6, handheld component 7, deep-slotted chip breaker 8, cross coordinate 9.Described ruler body 1 one end is fixedly connected with semicircle protractor 2, and top is provided with level meter 3, compass 4, longitude-latitude coordinates 5, handheld component 7, deep-slotted chip breaker 8, and described ruler body 1 another surface relative with handheld component 7 is provided with fixture 6.
Described level meter 3 centering horizontal plane, compass 4 is made a comment or criticism direction, and the judgement of longitude-latitude coordinates 5 for graticules and the judgement of 2 mutual alignments are multiple functional, easy to use.
