Embodiment
Below in conjunction with accompanying drawing, design and use of the present utility model are further illustrated.
Embodiment one:
As shown in Figure 1, be structural representation of the present utility model, this figure is the state of level line module 3 when not rising.For better reflecting the utility model structure, referring to accompanying drawing 2, the state when accompanying drawing 2 is 3 rise of level line module.In order further to reflect its inner structure, referring to accompanying drawing 3, accompanying drawing 3 is side views of the present utility model.The utility model comprises base plate 1, model seat 2, level line module 3, base plate 1 is fixedly connected with model seat 2, at model seat 2 middle parts, cut apart polylith closure and sheathed level line module 3 are arranged, and level line module 3 is identical with the thickness of model seat 2, and: level line module 3 bottoms by limit rope 4 with it the outside adjacent level line module 3(or model seat 2) bottom connects.
Use the time, can deduct inner most level line module 3 with hand, upwards mention.Just can intuitively reflect the landforms height.
Also need to prove: the outside of level line module 3 may be its peripheral level line module 3, may be also model seat 2.If the level line module 3 of outermost, its outside is not just the level line module, but model seat 2.So " level line module 3 bottoms by limit rope 4 with it the outside adjacent level line module 3(or model seat 2) bottom connects " the words is clearly, especially in this sentence, " perhaps " two words are clearly.
Because it is spacing that limited location rope 4 is used for, so when inner most level line module 3 was upwards mentioned, other level line modules 3 also can upwards be raised, and can not fall apart.
Embodiment two:
Teaching aid often is placed on the desk at front row, classroom, and so, rear row's student often can't see teaching aid.In order to make the student can see this teaching aid, can a support 5 be installed to the utility model.Referring to accompanying drawing 4 and accompanying drawing 5.Support 5 is to connect like this: be fixedly connected on base plate 1 below vertical with base plate 1.
Embodiment three:
For convenient demonstration, on the basis of embodiment two, the utility model is done further optimization: also comprise a hole 9 on base plate 1, and the position in hole 9 is positioned at inner most level line module 3 belows; Also comprise a push rod 6, the upper end of push rod 6 and inner most level line module 3 form a fixed connection, and push rod 6 passes hole 9.
When using, the teacher upwards boosts with handgrip push rod 6, just can become the level line of difference in height module 3 is arranged being in conplane level line module 3.The correlative technology field personnel should know the length of push rod 6 should be a suitable scope: too short, can't boost enough height, and oversize, touch to desktop, to such an extent as to level line module 3 can't become same plane.
Embodiment four:
Referring to accompanying drawing 7, the utility model can also comprise the air bag 7 that push rod 6 belows are fixedly connected with.When using, give air bag 7 inflations, air bag 7 is heaved, and push rod 6 jack-up is come, thereby realize that level line module 3 becomes the layout that difference in height is arranged from floor plan.
Related-art technology should be known: air bag 7 should have certain intensity, and air bag 7 will be used the opening that is used for inflation, venting.
Also need to prove, Figure of description should not contain other note except essential word." gas " and expression gas for Fig. 7 mark are filled with, and belong to essential word, so the arrow logo that " gas " and expression gas are filled with meets the patent examination guide.
Embodiment five:
Referring to accompanying drawing 8, this figure is the structural representation of embodiment five, simultaneously, sees also accompanying drawing 9, is the side view of the utility model embodiment five.The purpose of the present embodiment is to think explanation: the utility model can also comprise a sidewall box 8 that is positioned at model seat 2 sides and is fixedly connected with model seat 2, and the opening of sidewall box 8 is positioned at the top of sidewall box 8, and sidewall box 8 is made by transparent material.
The effect of this sidewall box 8 is such: isocontour teaching usually is linked together with the teaching of geological stratification, such as, underground have rock, the grains of sand, earth.In order to reflect intuitively the situation of geological stratification, in the utility model, sidewall box 8 can be set, sidewall box 8 the insides can sequentially be placed rock, the grains of sand, earth from bottom to top.
Embodiment six:
Structural representation referring to the utility model embodiment six---accompanying drawing 10, and the accompanying drawing 11 of reflection embodiment 6 side structures, the height of sidewall box 8 is: the top of sidewall box 8 is concordant with model seat 2 upper ends, the bottom of sidewall box 8 is concordant with support 5 bottoms.Such setting has not only increased the degree of depth of sidewall box 8, be conducive to put more multi-layered, and, can block the mechanism of base plate 1 below, look not in disorder.
The teacher can greenweed, desert, etc. be plotted to the upper surface of level line module 3 and model seat 2, with more vivid, directly perceived.
The utility model is that the level line teaching has offered a kind of new technical scheme, the utlity model has advantage simple in structure, easy to use, and abstract level line is become landforms difference in height intuitively.
