Description
Technical field
The utility model is related to teaching aid technical fields, and in particular to a kind of novel solid geometry demonstration teaching aid.
Background technology
Solid geometry is an important branch in mathematical studying, and student, which learns plane geometry, only to be needed to draw in the plane
Respective graphical can be well understood by and learn, and the study of solid geometry needs good space imagining ability, this for
Beginner be one be difficult the problem of.More particularly to the section problem of solid geometry, only it is difficult to understand for by the imagination.Teacher is teaching
It is difficult that student is allowed to understand to award student's solid geometry and only draw by plane, and student's learning efficiency is low, and teacher's rate of giving lessons is also low, it is unfavorable with
The progress of teaching process.
Utility model content
The utility model is to solve the disadvantage that the prior art and deficiency, provides a kind of novel solid geometry demonstration teaching aid,
It can explicitly show the different cross section that square, square go out after cutting, the space imagining ability of training student.
To achieve the above object, the utility model provides following technical solution：
A kind of novel solid geometry demonstration teaching aid, it is characterised in that including frame, slide plate, slide bar, elastic string；The frame
Frame waits long fulcrum bars to form by 12；The strut includes sliding slot strut and straight slot strut；The sliding slot strut has cooperation slide plate
Two sliding slots, the sliding slot is respectively distributed on two adjacent long pole faces of strut；The straight slot strut has and can pass through slide plate
Straight slot；There is sliding slot on one adjacent long pole face of the straight slot；The slide plate is made of transparent material；In the slide plate plate face
Several through holes of equidistantly distributed；The top surface of the frame is made of four straight slot struts；The slide bar is opposite with one group of top surface
Straight slot strut sliding slot cooperate；The frame facet is made of with bottom surface eight sliding slot struts；The slide plate passes through
The straight slot insertion frame facet of frame top surface, support is fixed by the sliding slot of sliding slot strut；The frame bottom surface, one group opposite
Sliding slot strut between have slide bar, cooperate with the sliding slot of sliding slot strut；There is fixing piece at the elastic string both ends；The elasticity
Rope connects slide plate and slide plate, slide bar and slide bar, slide bar and slide plate by fixing piece；The elastic string is at least three；The bullet
Property rope forms geometric figure in frame.
Preferably, the strut is fixed by binding agent.
Preferably, the sliding slot that the slide bar is matched therewith intersects vertically, and slide bar can slide in sliding slot.
Preferably, the fixing piece is the memory metal sheet of whip coil structures；The fixing piece width is less than slide plate through hole
Diameter；The fastener length is more than slide bar circumference.
The utility model use principle is as follows：By the frame that square is mutually combined between strut.Slide plate passes through one
A straight slot strut, is inserted on the face of square, is fixed by three sliding slot struts.Slide bar can be directly vertically caught in sliding slot, and
It can be along runner movement.It is the memory metal sheet of whip coil structures between the fixation at elastic string both ends, can be worn when fixing piece stretches
The through hole on slide plate is crossed, by the interaction between elastic force, straight line is pulled into inside square.When fixing piece crimps, then
It can be looped around on slide bar.Through hole is fixed on slide plate, can set common particular point directly to be used on teaching aid, and
Slide bar can move in sliding slot, and the fixing piece of elastic string can move on slide bar, then slide bar cooperation elastic string can be realized
Any position reconnaissance on one face of square.
Compared with prior art, the beneficial effects of the utility model are：The utility model structure setting is reasonable, functional
By force, has the following advantages：
1st, it is easy to use, by adjusting the position of elastic string, with reference to slide bar and slide plate, you can be spliced into the sky of definite shape
Between figure；
2nd, the demonstration of a variety of square geometrical issues is met, auxiliary student answers solid geometry problem, convenient for old
Teacher shows solid geometry relevant issues, improves student's space imagining ability.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model sliding slot branching rod structure schematic diagram.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
A kind of novel solid geometry demonstration teaching aid as shown in Figure 1 and Figure 2, including frame 1, slide plate 2, slide bar 3, elastic string
4.The square frame that frame 1 waits long fulcrum bars bonding to build composition for 12, wherein four struts of square top surface are straight slot
Eight struts of strut 10, side and bottom surface are sliding slot strut 9.
Slide plate 2 has four pieces, is inserted into respectively in the straight slot 7 of straight slot strut 10, forms four sides of square, and by other
The sliding slots 6 of three sliding slot struts 9 is fixed.Slide plate 2 makes for transparent material, and nine through holes are equidistantly arranged on slide plate 2
