The utility model discloses can be when the teacher explains the cycloid with the knowwhy entityization, the student of being convenient for understands the content of learning directly perceivedly, improves the teaching efficiency.
Description
Technical field
The utility model relates to a kind of teaching aid, the cycloid teaching aid that especially a kind of College Mathematics Teaching uses.
Background technology
Cycloid be a circle when rolling along straight line the upper point of fixity of circle the track of process, in current mathematical education, teacher can only explain the teaching of cycloid by abstract concept, do not demonstrate the teaching aid of cycloid, makes the stripe shape of student's indigestion and drafting cycloid.
Summary of the invention
The purpose of this utility model is the cycloid teaching aid providing a kind of College Mathematics Teaching to use, teacher, when carrying out cycloid teaching, by the content substance of cycloid, can explain cycloid more intuitively, make student understand better and draw cycloid, be convenient to students lecture contents.
Realize above-mentioned purpose, the utility model takes following technical proposals: the cycloid teaching aid that a kind of College Mathematics Teaching uses, and comprises disk, annular lug, two columns, two support rails, four suckers, several circular holes and several concentric circless,
Two described columns are along being vertically set up in parallel, the top and bottom at two column back sides are all inlaid with a sucker, two opposite flanks of two columns are provided with groove one along short transverse respectively, two described support rail levels and be disposed in parallel between two columns up and down, the two ends of two support rails are all fixed in the groove one of insertion two columns, two opposite flanks of two support rails are provided with groove two respectively along its length, the centre position of the external peripheral surface of described disk is fixed with annular lug, the width of described groove two is identical with the width of groove one, and be all greater than the thickness of annular lug, disk is rolled with the groove two of two support rails by the annular lug on it and is connected, several concentric circless are carved with in disk front, each described concentrically ringed optional position is circumferentially provided with a circular hole, the length of support rail is greater than the concentrically ringed girth of largest diameter.
Compared with prior art, the beneficial effects of the utility model are: the cycloid teaching aid that College Mathematics Teaching of the present utility model uses has reasonable in design, simple, practical feature.The utility model when teacher explains's cycloid by knowwhy hypostazation, can be convenient to student and understand content intuitively, improves efficiency of teaching.
Accompanying drawing explanation
Fig. 1 is the one-piece construction axonometric drawing of the cycloid teaching aid that College Mathematics Teaching of the present utility model uses;
Component names shown in figure and label as follows:
1-column; 2-support rail; 3-concentric circles; 4-disk; 5-annular lug; 6-circular hole; 7-sucker.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model is clearly and completely described; obviously; described embodiment is only a part of embodiment of utility model; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses the cycloid teaching aid that a kind of College Mathematics Teaching uses, comprise disk 4, annular lug 5, two columns 1, two support rails 2, four suckers 7, several circular holes 6 and several concentric circless 3,
Two columns 1 are along being vertically set up in parallel, the top and bottom at two column 1 back sides are all inlaid with a sucker 7, two opposite flanks of two columns 1 are provided with groove one along short transverse respectively, two support rail 2 levels and be disposed in parallel between two columns 1 up and down, the two ends of two support rails 2 are all fixed in the groove one of insertion two columns 1, two opposite flanks of two support rails 2 are provided with groove two respectively along its length, disk 4 is transparent plastic disk, the centre position of the external peripheral surface of disk 4 is fixed with annular lug 5, the width of groove two is identical with the width of groove one, and be all greater than the thickness of annular lug 5, disk 4 is rolled with the groove two of two support rails 2 by the annular lug 5 on it and is connected, several concentric circless 3 are carved with in disk 4 front, the optional position circumferentially of each concentric circles 3 is provided with a circular hole 6, the diameter of several circular holes 6 is identical and be less than the minimum concentric circles of diameter 3, the length of support rail 2 is greater than the girth of the concentric circles 3 of largest diameter.
Serve as a teacher use the utility model carry out cycloid teaching time, first four suckers 7 at two column 1 back sides are fixed on blackboard, then, select a concentric circles 3 needed in several concentric circless 3 on disk 4, and chalk is inserted in the circular hole 6 on this concentric circles 3, drive disk 4 to rotate with chalk, cycloid can be drawn out on blackboard simultaneously, after completing drafting, four suckers 7 depart from blackboard, and cycloid teaching aid of the present utility model is placed on desired location.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other dress bodily form formula.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the condition of equivalent by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
