Description
Technical field
The utility model relates to cycloid technical field, particularly relates to the cycloid teaching aid that a kind of College Mathematics Teaching uses.
Background technology
In mathematics, cycloid is defined as, circle along straight line move when, the formed rail of the upper fixed point of round edge circle
Mark, if you cut a circle with hardboard, fixes a pencil at the edge of circle, when this circle rolls along straight line, and pencil
A cycloid will be drawn. believe that the many people of such toy have seen playing, but in daily teaching, do not drill
Show the teaching aid that cycloid is formed, be unfavorable for that student understands cycloid, make troubles to cycloid teaching.
Content of the invention
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of College Maths religion proposing
Learn the cycloid teaching aid using.
To achieve these goals, the utility model adopts the technical scheme that
The cycloid teaching aid that a kind of College Mathematics Teaching uses, including base plate, described base plate is provided with backboard, described backboard
Top is fixed with top board, and the composition I-shaped structure of base plate, backboard and top board, and described base plate and top board are equipped with chute,
Said two chute is on same vertical plane, and is embedded with wheel disc between two chutes, and described wheel disc is provided with fixing hole, and
Fixing hole circumferentially equidistantly distributes in wheel disc, and described backboard outer wall is fixed with manuscript paper by pin.
Preferably, the quantity of described fixing hole is three to six.
Preferably, it is provided with spring clip inside described fixing hole.
Preferably, the quantity of described pin is four to six.
In the utility model, make this practical product production cost low by the design of simple base plate, backboard and top board, Gu
Determining to be fixed with in hole pencil, can drawing cycloid by rotating wheel disk, using method is simple, it is easy to promote the use of, fixing hole energy
Strong fixing several pencils, draw several cycloids in manuscript paper simultaneously, are easy to Students ' Learning, can strengthen teaching in classroom instruction
Effect.
Brief description
Fig. 1 is the Facad structure schematic diagram of the cycloid teaching aid that a kind of College Mathematics Teaching that the utility model proposes uses；
Fig. 2 is the side structure schematic diagram of the cycloid teaching aid that a kind of College Mathematics Teaching that the utility model proposes uses.
In figure: 1 base plate, 2 backboards, 3 top boards, 4 manuscript paper, the 5th, pin 6 chute, 7 wheel discs, 8 fixing holes.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
The cycloid teaching aid using with reference to Fig. 1, a kind of College Mathematics Teaching, including base plate 1, base plate 1 is provided with backboard 2, the back of the body
The top of plate 2 is fixed with top board 3, and the composition I-shaped structure of base plate the 1st, backboard 2 and top board 3, and base plate 1 and top board 3 are all provided with
Having chute 6, said two chute 6 is on same vertical plane, and is embedded with wheel disc 7 between two chutes 6, and wheel disc 7 is provided with
Fixing hole 8, and fixing hole 8 equidistantly distributes on wheel disc 7, and backboard 2 outer wall is fixed with manuscript paper 4 by pin 5, by letter
Single base plate the 1st, backboard 2 and top board 3 design make this practical product production cost low, are fixed with pencil, by manuscript paper in fixing hole 8
4 are fixed on backboard 2 with pin, can draw cycloid by rotating wheel disk 7, and using method is simple, it is easy to promote the use of, fixing
Hole 8 can fix several pencil effectively, draws several cycloids simultaneously, be easy to Students ' Learning, can increase in classroom instruction in manuscript paper 4
Strong teaching efficiency.
During this experiment is novel, the quantity of fixing hole 8 is three to six, and fixing hole 8 is internal is provided with spring clip, pin 5
Quantity is four to six, is designed by simple base plate the 1st, backboard 2 and top board 3 and makes this practical product production cost low, fixing
Hole 8 is fixed with pencil, manuscript paper 4 pin is fixed on backboard 2, cycloid, using method can be drawn by rotating wheel disk 7
Simply, it is easy to promote the use of, fixing hole 8 can fix several pencil effectively, draws several cycloids, in classroom in manuscript paper 4 simultaneously
It is easy to Students ' Learning in teaching, teaching efficiency can be strengthened.
Operation principle: be embedded in wheel disc 7 in the chute 6 of base plate 1 and top board 3, make wheel disc 7 move along a straight line on base plate 1,
Fix manuscript paper 4 by pin 5 on backboard 2, wheel disc 7 arranges fixing hole 8, in fixing hole 8, accompany pencil, work as wheel
Dish 7 is when rolling, and pencil can draw cycloid on manuscript paper 4.
The above, only the utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art is in the technical scope that the utility model discloses, according to this practicality
Novel technical scheme and utility model thereof conceive in addition equivalent or change, all should cover at protection model of the present utility model
