Abstract
The utility model discloses a continental plate movement demonstration instrument which comprises a bottom casing. A first elastic plate and a second elastic plate are symmetrically laid on the bottom casing. The side wall of the bottom casing is provided with a guide-track groove. Two automotive chassises are arranged inside the bottom casing. The automotive chassises are provided with guide-track rollers which can slide inside the guide-track groove. The automotive chassises are hinged to connecting rods, inside which telescopic links are sleeved. One automotive chassis is connected with the first elastic plate through the connecting rods and the telescopic links. The other automotive chassis is connected with the second elastic plate through the connecting rods and the telescopic links. The automotive chassises are provided with handles. When the continental plate movement demonstration instrument is in use, the arrangement of scale is convenient for demonstrating extrusion degree, and the arrangement of the connecting rods and the telescopic links is convenient to pressurize the first elastic plate and the second elastic plate to be elongated. Thus, it is convenient for the demonstration process. The continental plate movement demonstration instrument has a simple structure and is convenient to use. By the adoption of the continental plate movement demonstration instrument, continental plate movement and orogenic movement can be more visually demonstrated.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically relates to a kind of continental-bearing plate activity demonstrator.
Background technology
In geographical teaching, continental-bearing plate active presentation, is a kind of relatively abstract concept, and bad demonstration does not have the activity of a kind of suitable teaching aid demonstration continental-bearing plate now, and teacher can only demonstrate with the bending of book paper.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of continental-bearing plate activity demonstrator, and this continental-bearing plate activity demonstrator can be demonstrated continental-bearing plate activity and orogenic movement easily.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of continental-bearing plate activity demonstrator, comprise drain pan, the top symmetry of described drain pan is covered with the first elastic plate and the second elastic plate, on the sidewall of described drain pan, have guide-track groove, be provided with two groups of vehicle frames in described drain pan, vehicle frame is provided with the guide rail wheel that can slide in guide-track groove, on vehicle frame, be hinged with connecting rod, in described connecting rod, be socketed with expansion link, one group of vehicle frame is connected with the first elastic plate with expansion link by connecting rod, and another group vehicle frame is connected with the second elastic plate with expansion link by connecting rod; Described vehicle frame is provided with handle.
Below the further improvement to technique scheme:
One group of vehicle frame is provided with 8 guide rail wheels; One group of vehicle frame is provided with 4 groups of connecting rods and expansion link.
Connecting rod and expansion link arrange on the position near the first elastic plate and the second elastic plate middle part.
On drain pan, be vertically connected with baffle plate; Described baffle plate is provided with scale.
When use, the degree that convenient demonstration extruding is set of scale, arranging of connecting rod and expansion link is conveniently to extend at the first elastic plate and the pressurization of the second elastic plate, facilitate presentation process, the utility model is simple in structure, easy to use, can demonstrate more intuitively continental-bearing plate motion and orogenic movement.
Below in conjunction with accompanying drawing, the utility model is further described.
brief description of the drawings
The structural representation of a kind of continental-bearing plate activity demonstrator of accompanying drawing 1 the utility model embodiment;
Accompanying drawing 2 is the vertical view of accompanying drawing 1;
The structural representation that accompanying drawing 3 is vehicle frame.
In figure:
1-the first elastic plate; 2-drain pan; 3-guide-track groove; 4-guide rail wheel; 5-vehicle frame; 6-handle; 7-connecting rod; 8-expansion link; 9-baffle plate; 10-scale; 11-the second elastic plate.
Embodiment
Embodiment, as accompanying drawing 1, shown in accompanying drawing 2 and accompanying drawing 3, a kind of continental-bearing plate activity demonstrator, comprise drain pan 2, the top symmetry of described drain pan 2 is covered with the first elastic plate 1 and the second elastic plate 11, on the sidewall of described drain pan 2, there is guide-track groove 3, in described drain pan 2, be provided with two groups of vehicle frames 5, vehicle frame 5 is provided with can be at the guide rail wheel 4 of guide-track groove 3 interior slips, on vehicle frame 5, be hinged with connecting rod 7, in described connecting rod 7, be socketed with expansion link 8, one group of vehicle frame 5 is connected with the first elastic plate 1 with expansion link 8 by connecting rod 7, another group vehicle frame 5 is connected with the second elastic plate 11 with expansion link 8 by connecting rod 7, described vehicle frame 5 is provided with handle 6.
One group of vehicle frame 5 is provided with 8 guide rail wheels 4; One group of vehicle frame 5 is provided with 4 groups of connecting rods 7 and expansion link 8.
Connecting rod 7 and expansion link 8 are arranged between two guide rail wheels 4 of homonymy.
Connecting rod 7 and expansion link 8 arrange on the position near the first elastic plate 1 and the second elastic plate 11 middle parts.
On drain pan 2, be vertically connected with baffle plate 9; Described baffle plate 9 is provided with scale 10.
When work, the first elastic plate 1 and the second elastic plate 11 represent respectively two continental-bearing plates, mobile two groups of vehicle frames 5, two groups of vehicle frames 5 are close, the first elastic plate 1 contacts, pushes with the marginal portion of the second elastic plate 11, because the first elastic plate 1 and the second elastic plate 11 are elastic plate, the first elastic plate 1 and the second elastic plate 11 contact portions raise, and complete presentation process.
The degree that convenient demonstration extruding is set of scale 10, arranging of connecting rod 7 and expansion link 8 is conveniently to extend at the first elastic plate 1 and the second elastic plate 11 pressurizations, facilitated presentation process, and the utility model is simple in structure, easy to use, can demonstrate more intuitively continental-bearing plate motion and orogenic movement.
