Abstract
The utility model discloses a fold demonstration ware relates to teaching aid equipment field, and the inner wall symmetry of this fold demonstration ware's braced frame's both sides is equipped with two rectangular plate shaped's push pedal, and the braced frame both sides are equipped with two bolts, bolt and braced frame screw -thread fit, and top -down is equipped with top layer pad, alar part pad, middle level pad, nuclear portion pad, five layers of flexible gasket of ground floor mat between two push pedals. Top layer pad, alar part pad, middle level pad, nuclear portion pad, ground floor mat adopt the flexiplast manufacturing of different materials and different colours respectively, have represented by last different stratum under to, and the push pedal that promotes both sides through the bolt that rotates both sides promotes five layers of flexible gasket and arches to the centre to vividly demonstrate out the process that crustal movement arouses the fold phenomenon, deepen student's influence.
Description
Technical field
This utility model relates to teaching aid apparatus field, particularly to a kind of fold demonstration device.
Background technology
Fold is the bending that various stress in rock occur and the deformation shown, is originally to be bordering on straight face in rock to become curved surface and show.The deformation plance overwhelming majority forming fold is bed plane；The primary stream interface etc. of the cleavage of metamorphic rock, sheet reason or gneissosity and magmatic rock also can become fold face；Sometimes joint plane, fault plane or the plane of unconformity in rock stratum and rock mass, is likely to deformation and forms fold after stress.Fold is one of knowledge point required on middle school geography textbook.
Present geography teachers, when lecturing fold knowledge, allows student see that photo is understood often, is difficult to allow student dynamically understand the process that fold is formed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fold demonstration device, arranges the layer model that five layers of flexible material manufacture, and install push pedal and bolt in model both sides, to demonstrate the forming process of fold in the support frame that cross section is U-shaped.
For achieving the above object, the technical scheme that this utility model offer is following: a kind of fold demonstration device, it is characterized in that: described fold demonstration device includes the support frame that a cross section takes the shape of the letter U, the inwall of the both sides of support frame is arranged with the push pedal of two rectangular plate-like, support frame both sides are provided with two bolts, bolt and support frame threaded engagement, and bolt contacts through support frame with push pedal, top layer pad it is provided with from top to bottom between two push pedals, alar part pad, middle level pad, core portion pad, five layers of flexible gasket of bottom pad, the push pedal of between five layers of pad and five layers of pad and both sides is all by together with adhesives.
Preferably, described top layer pad is manufactured by elastomeric material.
Preferably, described alar part pad is manufactured by polytetrafluoroethylmaterial material.
Preferably, described core portion pad is manufactured by polyurethane material.
Preferably, described core portion pad is manufactured by polyurethane material.
Preferably, described bottom pad is manufactured by makrolon material.
Above technical scheme is used to provide the benefit that: the inwall of the both sides of the support frame of this fold demonstration device is arranged with the push pedal of two rectangular plate-like, support frame both sides are provided with two bolts, bolt and support frame threaded engagement, be provided with top layer pad, alar part pad, middle level pad, core portion pad, five layers of flexible gasket of bottom pad from top to bottom between two push pedals.Top layer pad, alar part pad, middle level pad, core portion pad, bottom pad are respectively adopted the flexiplast manufacture of unlike material and different colours, represent Different Strata from top to bottom, five layers of flexible gasket are promoted to arch upward to centre by rotating the push pedal on the bolt pusher both sides of both sides, thus vivo demonstrate out crustal movement and cause the process of buckling phenomena, deepen the impact of student.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the front view of this utility model a kind of fold demonstration device；
Fig. 2 is the top view of this utility model a kind of fold demonstration device.
Wherein, 1--support frame, 2-push pedal, 3-bolt, 4-top layer pad, 5-alar part pad, 6-middle level pad, 7--core portion pad, 8-bottom pad.
Detailed description of the invention
Describe the preferred implementation of this utility model a kind of fold demonstration device below in conjunction with the accompanying drawings in detail.
Fig. 1 and Fig. 2 shows the detailed description of the invention of this utility model a kind of fold demonstration device: this fold demonstration device includes the support frame 1 that a cross section takes the shape of the letter U, the inwall of the both sides of support frame 1 is arranged with the push pedal 2 of two rectangular plate-like, support frame 1 both sides are provided with two bolts 3, bolt 3 and support frame 1 threaded engagement, and bolt 3 contacts through support frame 1 with push pedal 2, top layer pad 4 it is provided with from top to bottom between two push pedals 2, alar part pad 5, middle level pad 6, core portion pad 7, 8 five layers of flexible gasket of bottom pad, the push pedal 2 of between five layers of pad and five layers of pad and both sides is all by together with adhesives.
In conjunction with Fig. 1 and Fig. 2, top layer pad 4 is manufactured by elastomeric material, remains the black of rubber.Alar part pad 5 is manufactured by polytetrafluoroethylmaterial material, and stained yellow.Middle level pad 6 is manufactured by vinyl chloride resin material, and dyes redness.Core portion pad 7 is manufactured by polyurethane material, and dyes green.Bottom pad 8 is manufactured by makrolon material, and dyes blueness.Using the form arrangement that light and dark color is alternate, aberration is huge, it is simple to observation of students.
Top layer pad 4, alar part pad 5, middle level pad 6, core portion pad 7, bottom pad 8 are respectively adopted the flexiplast manufacture of unlike material and different colours, represent Different Strata from top to bottom, the push pedal 2 on both sides is promoted to promote five layers of flexible gasket to arch upward to centre by rotating the bolt 3 of both sides, thus vivo demonstrate out crustal movement and cause the process of buckling phenomena, deepen the impact of student.
Above is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
