Description
Technical field
The utility model relates to teaching apparatus for mathematics, specifically relates to mathematics education model exhibiting device.
Background technology
In mathematical education, need often to use mathematical model.The history of mathematical model can trace back to the epoch that the mankind bring into use numeral.Along with the mankind use numeral, just constantly set up various mathematical model, to solve various practical problems.Mathematical model links up the requisite bridge contacted between practical problems and mathematical tool of confronting.
In order to improve the teaching efficiency of mathematics, teacher needs to use a large amount of mathematical models, so that student understands.Particularly in geometry teaching teaching process, need to use as model teaching aids such as geometric model, function curve demonstration boards.Because mathematics education model is many, be generally deposit in model casing, but in teaching process, the dais limited area of teacher, is inconvenient to show too much mathematical model.
Utility model content
The utility model provides a kind of mathematics education model show stand, and it is many that the utility model solves mathematics education model, and be generally deposit in model casing, in teaching process, the dais limited area of teacher, is inconvenient to show too much mathematical model problem.
For solving the problem, the utility model adopts following technical scheme: a kind of mathematics education model show stand, comprise exhibition booth pedestal, upper cover and model board for putting, exhibition booth pedestal is rectangular box uncovered above, upper cover covers at exhibition booth impact faces, on rear side of upper cover, there is circular card at two ends, and upper cover and exhibition booth pedestal are connected to form retractable structure by a rotating shaft through card and exhibition booth pedestal posterior edges; On front side of upper cover, be also provided with at least three block models board for puttings, model board for putting is arranged in parallel from bottom to top, and model board for putting back side edge two ends are connected to upper cover left and right side by jointed shaft; Two support bars are vertically arranged at the left and right sides of model board for putting respectively, and the front end of model board for putting is hinged with support bar respectively, model board for putting, form parallelogram lindage between support bar and upper cover; Respectively have a rectangle hole clipping at exhibition booth pedestal left and right sides, there is rectangle buckle support bar lower end, and when model board for putting is in horizontality, rectangle buckle coordinates with rectangle hole clipping.
The utility model feature: one, exhibition booth of the present utility model pedestal is rectangular box uncovered above, can hold a large amount of mathematical education moulds; Two, in teaching process, upper cover can be opened, when upper cover is in erectility, spacing lever can prevent upper cover from facing upward to rear side, now pull out support bar, model board for putting turns to horizontality to front side, is now embedded in rectangle hole clipping by the rectangle buckle of support bar lower end, now, model board for putting can be fixed; Model board for putting is placed the model teaching aid needing to show; Three, when not, the rectangle buckle of support bar lower end can be pulled out, promote model board for putting and upwards turn up, now model board for putting can be stacked on upper cover inner top surface, is positioned over by model in the pedestal of exhibition booth, closes up upper cover; Four, model display platform can, at a certain learning phase, be positioned in classroom by teacher, and multilayered model board for putting can show a large amount of teaching mode, facilitates student to understand; Five, the utility model does not need the dais taking teacher, can be positioned over interior wall limit, classroom, show more mathematical model, also has the function of storage model, teaching aid simultaneously, puts and just impart knowledge to students; Six, when model does not need to use, support can be contracted, make overall formation one box-shaped, put and just move.
Accompanying drawing explanation
Fig. 1 is the utility model side view; Fig. 2 is the vertical view of Fig. 1; Fig. 3 is the utility model upper cover opening schematic diagram; Fig. 4 is that in Fig. 3, model board for putting launches to look intention; Fig. 5 is the A-A cutaway view Amplified image of Fig. 4; Fig. 6 is the utility model using state figure.
Symbol description in figure: exhibition booth pedestal 1, upper cover 2, spacing lever 3, card 4, model board for putting 5, support bar 6, rectangle hole clipping 7, rectangle buckle 8.
Embodiment
By best embodiment, the utility model is described in detail below.
As Figure 1-3, exhibition booth pedestal 1, upper cover 2 and model board for putting 5 are made for plastics, and support bar 6 is plastics or metallic rod body.Upper cover 2 comprises end face and front, left and right side, and the side of upper cover is buckled in exhibition booth pedestal outside suitable for reading.Upper cover 2 left and right side and circular card 4 are connected as a single entity structure.On rear side of exhibition booth pedestal 1, coboundary has right cylinder, and rotating shaft is through right cylinder, and rotating shaft two ends are connected in the hole of card 4, and such upper cover 2 and exhibition booth pedestal 1 can form the opening-closing structure of folding paper.Also be connected with a spacing lever 3 between two cards 4 on rear side of upper cover 2, during upper cover 2 erectility, spacing lever 3 is stuck on exhibition booth pedestal 1 trailing flank.
As Figure 4-Figure 6, can arrange 3-6 block models board for putting 5 on front side of upper cover 2, model board for putting 5 is arranged in parallel from bottom to top, and model board for putting 5 back side edge two ends are connected to upper cover 2 left and right side by jointed shaft.Two support bars 6 are vertically arranged at the left and right sides of model board for putting 5 respectively, and the front end of model board for putting 5 is hinged with support bar 6 respectively, model board for putting 5, form parallelogram lindage between support bar 6 and upper cover 2; Respectively have a rectangle hole clipping 7 at exhibition booth pedestal 1 left and right sides, there is rectangle buckle 8 support bar 6 lower end, and rectangle buckle 8 and rectangle hole clipping 7 closely cooperate, and prevent support bar from rotating, make model board for putting Stability Analysis of Structures.Support bar can slightly elasticity, facilitates drawing rectangle buckle like this.When upper cover closes up, model board for putting is stacked together mutually, and is placed in upper cover top.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
