The utility model has the characteristics of the transform rapidly, the knowledge point show is efficient, the demonstration feels strong etc, and the utility model discloses can increase student's enthusiasm and interest in learning. (B, )
Description
Technical field
the utility model relates to a kind of teaching aid, the geometry teaching aid of particularly a kind of mechanical drawing.
Background technology
space geometry is the knowledge point of college course " mechanical drawing " chapter 2, comparatively dry as dust, but is widely used in machine design and manufacture field.And lecturer is because of its abstract key concept and content, as the intersecting body in projection, analyse and observe body, drafting of part drawing wiring layout etc., student, to the shortage of concept of space, gives lessons to lecturer, student listens to the teacher and bring great inconvenience in addition outward.Existing teaching aid is many as the fixing stereoscopic model made by PVC plastic in the market, a set ofly needs 2000-4000 unit not, and can not be split, and using value is more limited.And some are spelled and take the geometry teaching aid of form, the geometric relationship on some bases often can only be demonstrated, inapplicable in college course.
Utility model content
the purpose of this utility model is, provides a kind of geometry teaching aid of mechanical drawing.The utility model has conversion rapidly, and the features such as efficiency is high, and demonstration sense is strong are shown in knowledge point; And the utility model can increase Students' enthusiasm and learning interest.
the technical solution of the utility model: a kind of geometry teaching aid of mechanical drawing, comprises mutual H projecting plane perpendicular to each other, V projecting plane and W projecting plane, and H projecting plane, V projecting plane and W projecting plane are provided with the lamp pearl of latticed form arrangement; Above H projecting plane, be provided with bearing, bearing is provided with the projection thing be made up of lamp bar, and lamp bar and lamp pearl via line are connected with controller.
in the geometry teaching aid of above-mentioned mechanical drawing, the bottom on described H projecting plane is provided with rotating disk.
in the geometry teaching aid of aforesaid mechanical drawing, filled by organic glass thin plate in the middle of described projection thing.
compared with prior art, the utility model can pass through programmed control, and change the light on and off of LED, color shows point, line, surface and projection thereof at many levels.The utility model has conversion rapidly, knowledge point shows that efficiency is high, the features such as demonstration sense is strong, classroom atmosphere can be promoted, increase Students' enthusiasm and learning interest are in addition, all-transparent structure contributes to student 360 degree and observes model, by the demonstration of certainly establishing program can change figure, increases study specific aim.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is circuit theory diagrams of the present utility model;
fig. 3 is use principle figure of the present utility model.
Embodiment
below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
embodiment: a kind of geometry teaching aid of mechanical drawing, form as depicted in figs. 1 and 2, comprise mutual H projecting plane 1 perpendicular to each other, V projecting plane 2 and W projecting plane 3, and H projecting plane, V projecting plane and W projecting plane all can adopt organic glass, H projecting plane 1, V projecting plane 2 and W projecting plane 3 are embedded with lamp pearl 4, and lamp pearl 4 is with latticed form arrangement, lamp pearl 4 via line is connected with controller 8.Plastic seating 5 is fixed with above H projecting plane 1, bearing 5 is provided with the projection thing 7 be made up of lamp bar 6, buckle or draw-in groove can be adopted to fix between bearing 5 and projection thing 7, lamp bar can adopt the plexi-glass tubular of certain bending strength, or adopt conventional clear glass, plastic tube, be fixed by organic glass thin plate 10 in the middle of pipe, in pipe, LED lamp bead is set, formation can alight bar 6, lamp bar via line is also connected with controller 8, as shown in Figure 2, lamp pearl 4 and lamp bar 6 can adopt series system to be connected with controller 8.The bottom on described H projecting plane 1 is provided with rotating disk 9, and this teaching aid can 360 degree be shown.Using method of the present utility model is fixed on bearing by projection thing, and lamp bar is the line forming projection thing.Controller is connected with telepilot, and telepilot manually inputs the option order of this projection thing, and via controller drives certain root lamp bar of projection thing bright, and the lamp pearl on projecting plane corresponding to this lamp bar is bright, shows, the projection of this bright light to reach teaching purpose.
as shown in Figure 3, projection thing 7 can be two and intersect fixing right-angle triangle model A plate 11 and B plate 12, the frame of described two right-angle triangle models is barricaded as with plexi-glass tubular, fill with organic glass thin plate in the middle of described triangle model, the each little ball that described plexi-glass tubular is embedded in represents a LED, described LED exists with the series connection of lamp strips in pipe, described LED lamp bar is external to controller, described LED often bright one to represent in space a bit, light straight line and represent straight line, plane method for expressing is also like this.
as shown in Figure 3, A plate 11 is parallel to V projecting plane, and B plate 12 is parallel to H projecting plane, and the hypotenuse 13 of A plate 11 is perpendicular to W projecting plane, and B plate hypotenuse 14 is perpendicular to V plane.Therefore the long right-angle side 15 of described A plate is frontal line, the long right-angle side 16 of B plate is horizontal line, B plate hypotenuse 14 is vertical frontal line, A plate hypotenuse 13 is vertical profile line, and A plate 11 is vertical plane, and B plate 12 is surface level, the long right-angle side 15 of A plate and B plate hypotenuse 14 intersect for line line, A limit hypotenuse 13 and B plate hypotenuse 14 different surface beeline each other, B plate hypotenuse 14 and A plate are segment-Facet intersection, and A plate and B plate are that face, face is intersected.As shown in Figure 3, in A plate and B plate, LED makes it entirely bright by programming, and on projecting plane, the projection of opposite position also can be arranged by controller in advance and light, and all the other points do not work.Different point, line, surface elements can the LED of different colours be lighted.
