Abstract
The utility model provides a digital rotary drum for elementary mathematical education, it includes the rotary drum body, the rotary drum body is in by pivot and cover it constitutes to change the epaxial lantern ring, the lantern ring be six and all with pivot rotatable coupling the lantern ring on be equipped with display panels respectively, be parallel to each other after having at least display panels to rotate on two adjacent lantern rings. The utility model discloses a digital rotary drum for elementary mathematical education has adopted the rotary drum structure of sectional type, it can pivoted digit face to have set up respectively in each section, just can make up into the mathematical formula of multiple difference and the figure pattern of show difference through rotating different mathematics faces like this, the pattern is unique, appeal to the student is great, very good teaching bandwagon effect has, and weight is lighter, use and carry all very convenient, the price is also cheap relatively, and has good application value.
Description
Technical field
This utility model relates to a kind of mathematical tool, especially a kind of digital rotating cylinder for primary mathematical education, belongs to teaching equipment technical field.
Background technology
In primary mathematical education, teacher not only to consider the content of teaching, is also required to think deeply the attention how attracting student simultaneously, improves student learning interest. The big multi-mode of now current teaching method is relatively fixed, usually carry out writing on blackboard and corresponding explanation, this mode is owing to planarizing very much, captivation for students is more weak, therefore, it is difficult to cause the interest of students so that teaching efficiency is also made a discount, along with the propelling of the reform in education, increasing school starts to introduce new tutor auxiliary platform equipment and instrument, and also progressively introduces in teaching aid equipment mathematical education.
Utility model content
For above-mentioned deficiency of the prior art, main purpose of the present utility model is in that to solve the existing problem lacking the aid that can attract attention of student at present in mathematical education, and the digital rotating cylinder for primary mathematical education a kind of new style being provided, teaching through lively activities.
The technical solution of the utility model: a kind of digital rotating cylinder for primary mathematical education, it is characterized in that, including drum body, described drum body is to be made up of rotating shaft and the collar being enclosed within described rotating shaft, the described collar is six and is all rotatably connected with rotating shaft, the described collar is respectively equipped with display surface, two adjacent collars has at least a display surface be parallel to each other after rotating.
Optimally, between two adjacent collars, it is additionally provided with elastic washer. The abrasion between the collar can be reduced, it is to avoid the collar blocks by arranging elastic washer.
Optimally, the cross section of the described collar is regular hexagon. Adopt orthohexagonal structure to have good outward appearance intelligibility, operate also very convenient.
Optimally, the cross section of the described collar is regualr decagon.Adopt decagon structure to have and more content is set, thus reaching the effect of abundant content.
Optimally, the display surface on the described collar is square. Here after display surface being optimized, specification more, whether pattern or numeral can clearly indicate.
Relative to prior art, this utility model has the advantages that
Digital rotating cylinder for primary mathematical education of the present utility model have employed the barrel configuration of stagewise, each section is respectively provided with rotary numeral face, so just can be combined into multiple different mathematical formulae by the different mathematics face of rotation and show different pictorial patterns, pattern is unique, and the captivation for student is relatively big, has extraordinary teaching bandwagon effect, and lighter in weight, using and carry all very convenient, price is also relatively cheap, has good using value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of digital rotating cylinder for primary mathematical education of this utility model.
In figure, 1 drum body, 11 rotating shafts, 12 collars, 2 display surfaces, 3 elastic washers.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of digital rotating cylinder for primary mathematical education of the present utility model, including drum body 1, described drum body 1 is cylindrical structure, described drum body 1 is to be made up of rotating shaft 11 and the collar 12 being enclosed within described rotating shaft 11, and the described collar 12 is six and is all rotatably connected with rotating shaft 11. In this utility model, each collar 12 can individually rotate, and its rotating angle is 360 ��. The described collar 12 is respectively equipped with display surface 2, according to user demand, it is possible to the cross section of the described collar 12 is set to regular hexagon, it is also possible to the cross section of the described collar 12 is set to regualr decagon. When mounted, two adjacent collars have at least a display surface 2 be parallel to each other after rotating.
Referring to Fig. 1, in this utility model, between two adjacent collars 12, it is additionally provided with elastic washer 3, can effectively be reduced the friction between the adjacent collar and collision by described elastic washer 3, avoiding the situation occurring getting stuck when rotating, it nor affects on normal rotation and the use of the collar simultaneously. In order to improve bandwagon effect, specification more, the display surface 2 on the described collar 12 is disposed as square by this utility model.
It should be noted that, above example is only in order to illustrate technical solutions of the utility model but not restriction technologies scheme, although this utility model is explained in detail by applicant with reference to preferred embodiment, it will be understood by those within the art that, those amendments that technical solutions of the utility model are carried out or equivalent replacement, objective and the scope of the technical program can not be departed from, all should be encompassed in the middle of this utility model right.
