Description
Technical field
This utility model is related to instruction and office technical field, and in particular to a kind of teaching is with being easy to primary learn three geometry
Combination unit.
Background technology
At present, education and instruction teaching aid is varied, and three third dimensions of some students are not strong, and three for training student stand
Body-sensing, occurs the three-valued structures that many your sons meet the eye on every side on the market, but is that structure is complex mostly, and it be not especially square to use
Just, it is more difficult for the student of three solid figures is just contacted, the particularly observation to six views, its hiding dotted line table
Show etc., a kind of being suitable to impart knowledge to students with being easy to primary three geometrical combination devices of study to meet teaching and teacher is specifically designed for this
Need.
Utility model content
The purpose of this utility model is to provide a kind of teaching with three geometrical combination devices of primary study are easy to, by combination
Mode spliced, allow student to have the concept of visual pattern, this device is suitable to out the three-dimensional concept of scholar's culture, and its operation can
Realize drawing the different sketches of different composite figures by teacher, sketch is restored according to the combination of assembly then, is so learned
It is raw vivid to remember or sketch is drawn according to the different location graphic of solid, allow student to be easier to connect by simple teaching aid
Receive, using wooden structure, cheap, simple to operate, abecedarian's practicality is stronger, more preferable on year-on-year basis by putting into practice acceptable effect.
To achieve these goals, the technical solution of employing is this utility model：
A kind of teaching is with being easy to primary learn three geometrical combination devices, including body 1, it is characterised in that：Also include group
Framework 2, fixed cover 3, interior mobile layer 4, outer mobile layer 5 are closed, group frame 2 is consisted of two L shape frameworks, in two L-shaped
Rectangular through slot is simultaneously provided with the end face of shape framework, rectangle convex body is simultaneously fixed with, rectangle convex body coordinates shape with rectangular through slot
Into group frame 2, individual L shape framework can be slided in rectangular through slot by rectangle convex body and be misplaced, and body 1 is maintained static, this
Through hole is provided with body 1, fixed cover 3 in through hole, is inlayed, the chute opened in the protruding block on fixed cover 3 and interior mobile layer 4 coordinates, interior
Mobile layer is provided with chute about 4, it is convex that outer mobile layer 5 is fixed with 4 chute of interior mobile layer and 1 top edge groove of body coordinates
It is bittiness.
A kind of scheme：Through hole is provided with body 1, gap, fixed cover 3 is provided with four quadrantal points positions of round tube hole
Protruding block coordinates in gap.
The beneficial effect that this utility model can be produced：It is reasonable in design, simple structure, easy to use.
Description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is body, group frame, 3 combining structure schematic diagram of fixed cover.
Accompanying drawing 3 is fixed cover 3, interior mobile layer 4, the combination partial enlarged drawing of outer mobile layer 5.
Specific embodiment
Specific embodiment one
With reference to 1, Fig. 2, Fig. 3 explanation present embodiment, a kind of teaching is wrapped with three geometrical combination devices of primary study are easy to
Include body 1, it is characterised in that：Also include group frame 2, fixed cover 3, interior mobile layer 4, outer mobile layer 5, group frame 2 passes through
Two L shape framework compositions, are simultaneously provided with rectangular through slot on the end face of two L shape frameworks, are simultaneously fixed with rectangle convex
Body, rectangle convex body and rectangular through slot cooperatively form group frame 2, and individual L shape framework can be in rectangular through slot by rectangle convex body
Interior dislocation of sliding, body 1 maintains static, and through hole is provided with body 1, fixed cover 3 in through hole, the protruding block on fixed cover 3 with it is interior
The chute opened in mobile layer 4 coordinates, and interior mobile layer is provided with chute about 4, outer mobile layer 5 be fixed with 4 chute of interior mobile layer,
And the protruding block that body top edge groove coordinates.
The device allows student to understand the geometric figure of three, the third dimension of training student by incremental compound mode
Feel, the connected mode of each position can more highlight the practicality of the device, dismounting is more convenient, while group frame 2, interior activity
The layer 4, misconstruction of outer mobile layer 5 represents that the visual in image student that allows of energy understands, and wherein in body 1, fixed cover 3 and through hole are matched somebody with somebody
There is invisible position when side is observed when closing dislocation, which just can be drawn with dotted line when three-view diagram picture is taught, simply
Combination is directly perceived, has simple combination to start, gradually adds the different structure of the device, then promote a certain position as needed i.e.
Changeable shape.It is highly effective for begining to learn.Fixed cover 3, interior mobile layer 4,5 three groups of external members of outer mobile layer can be according to study
Need, by simple to difficulty, its each item is divided into four parts by fixed cover 3, interior mobile layer 4, outer mobile layer 5.
Specific embodiment two
Present embodiment, a kind of scheme are illustrated with reference to Fig. 1, Fig. 2, Fig. 3：Through hole is provided with body 1, in round tube hole
Four quadrantal points positions are provided with gap, and 3 protruding block of fixed cover coordinates in gap.Its body inner via hole inlays fixed cover 3, combination
2 two groups of framework is combined as simplest original combined, primary to start the incremental study of learner.Group frame and body according to
Need to can be set to different size specification, this device size is 20cmX15cmX10cm.
Certainly, described above is not that, to restriction of the present utility model, this utility model is also not limited to the example above,
Change, remodeling, addition or replacement that those skilled in the art are made in essential scope of the present utility model, also should
Belong to protection domain of the present utility model.
