Description

Three-dimensional contour line demonstration model
Technical Field
The utility model relates to a teaching model field, concretely relates to three-dimensional contour demonstration model.
Background
In the geography teaching process, can relate to the teaching content of mountain body contour line usually, the contour line refers to the closed curve that each point that the height equals on the topographic map links into, and current teaching in-process all draws the contour line on the blackboard by hand and teaches, and the relatively poor student of being convenient for of this kind of mode intuition nature understands, for this reason, the utility model provides a demonstration model through the solid model so that carry out audio-visual demonstration teaching to the contour line content.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a three-dimensional contour demonstration model to carry out audio-visual demonstration teaching to the peer-to-peer altitude content.
In order to solve the technical problem, the utility model adopts the following technical scheme:
three-dimensional contour line demonstration model, including the base, at base lower surface central hinge and be connected with the grab handle, the base upper surface is provided with the mountain model, the mountain model stacks from top to bottom by a plurality of model units and forms, and the model unit that is located upper portion is provided with mountain top and valley portion, and the model unit lateral part of lower part is connected and is formed the ridge portion, the base middle part is provided with the stand perpendicularly, and a plurality of model units wear to establish in the stand in proper order.
Furthermore, the base is a square plastic plate, and cushion blocks are arranged at four corners of the bottom of the base.
Further, the base bottom is provided with articulated seat, the grab handle upper end is connected with articulated seat hinge and the width of grab handle is less than the height of cushion, still be provided with the rubber sleeve on the grab handle.
Furthermore, contour lines are marked on the upper surface and the lower surface of the model unit, square holes are formed in the model unit, and square iron sleeves are arranged in the square holes.
Furthermore, the size of the upright post is matched with that of the square iron sleeve, and the upright post is a magnetic rod.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, convenient to use through being provided with cushion and grab handle bottom the base to demonstrate with it on placing the desk and be convenient for show moving the in-process, the massif model has polylith model unit to stack and forms, the separation of being convenient for demonstrates the contour line, the model unit passes through the stand to be fixed on the base, and the stand is the bar magnet and is provided with square iron cover in the model unit quad slit, make that every massif model can be better fix on the stand, be difficult for dropping.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of one of the model elements.
In the figure, 1-cushion block, 2-base, 3-hinged base, 4-grab handle, 5-rubber sleeve, 6-mountain model, 61-model unit, 62-mountain valley portion, 63-mountain top portion, 64-mountain ridge portion, 65-square hole, 66-square iron sleeve, 67-contour line and 7-upright column.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1:
referring to fig. 1, the utility model provides a three-dimensional contour line demonstration model, including base 2, be connected with grab handle 4 at base 2 lower surface central hinge, when the teacher of needs walks about to demonstrate this model, hold grab handle 4 through the hand and be convenient for remove, base 2 upper surface is provided with massif model 6, massif model 6 stacks from top to bottom by a plurality of model units 61 and forms, and model unit 61 can be made by light plastics or foam, and the size and the profile diverse of each model unit 61 are located the model unit 61 on upper portion and are provided with mountain top portion 63 and valley portion 62, and the model unit 61 lateral part of lower part is connected and is formed mountain ridge portion 64, base 2 middle part is provided with stand 7 perpendicularly, and a plurality of model units 61 wear to establish in stand 7 in proper order.
Example 2:
on the basis of the embodiment, the utility model discloses an another embodiment is, base 2 is square plastic slab, and 2 bottom four corners on the base are provided with cushion 1 to place and demonstrate on the lectern, when placing on the lectern, need rotate grab handle 4 to the position of laminating mutually with 2 bottom surfaces of base, 2 bottoms on the base are provided with articulated seat 3, 3 hinged connections of grab handle 4 upper end and articulated seat and grab handle 4's width are less than cushion 1's height, make to prevent to not rock on the lectern, still be provided with rubber sleeve 5 on the grab handle 4.
Example 3:
referring to fig. 2, another embodiment of the present invention is that the model unit 61 has contour lines 67 marked on its upper and lower surfaces, and the model unit 61 has square holes 65, and square iron sleeves 66 are disposed in the square holes 65.
