Abstract
An ellipsograph for teaching comprises a strip-shaped plate, a pulling rope and a chalk sleeve. The ellipsograph for teaching is characterized in that the strip-shaped plate is provided with a guide groove, the guide groove is provided with two sliding blocks capable of moving along the length direction of the guide groove, and two ends of the pulling rope are fixed on the two sliding blocks respectively. The length of the pulling rope is larger than that of the strip-shaped plate, and the two sliding blocks are provided with fixing screws for enabling the sliding blocks to be fixed on the strip-shaped plate. By arranging the strip-shaped plate provided with the guide groove, the sliding blocks capable of moving and positioning in the guide groove and the pulling rope connected with the sliding blocks, ovals of different specifications and accurate in sizes can be effectively drawn, and the ellipsograph for teaching is favorable for high-efficiency mathematics teaching and stimulation of learning interest of students.
Description
Technical field
The utility model relates to a kind of teaching and uses ellipsograph, in particular, relates in particular to a kind of teaching that can easily, accurately draw out different size specification ellipse and uses ellipsograph.
Background technology
In the teaching process of mathematics, carry out the transition to oval teaching by circle, not only teacher is one and is rich in challenging teaching task, and concerning the student, want to learn also oval character and theorem well very difficulty.For the ease of teacher's teaching and students'understanding, be badly in need of a kind of educational aid, can be directly perceived, image and like clockwork ellipse is drawn, be presented on students in face of; So both help teacher's efficient teaching, and also can excite the learning interest of students.
Summary of the invention
The utility model provides a kind of teaching that can easily, accurately draw out different size specification ellipse to use ellipsograph in order to overcome the shortcoming of above-mentioned technical problem.
Ellipsograph is used in the teaching of the utility model; Comprise stripe board, pull rope and chalk sleeve; Its special feature is: offer gathering sill on the said stripe board, gathering sill is provided with two sliding shoes that can move along the gathering sill length direction, and the two ends of pull rope are separately fixed on two sliding shoes; The length of said pull rope is greater than the length of stripe board, is provided with on two sliding shoes to be used for sliding shoe is fixed on the hold-down screw on the stripe board.Stripe board plays fixing and supporting role, and pull rope is realized the traction to chalk sleeve; Two sliding shoes are spacing in gathering sill, and can move along the gathering sill direction, and hold-down screw is used for sliding shoe is fixed on the specific location of gathering sill.Have only the length of the length of pull rope greater than stripe board, ellipse again can draw.
Ellipsograph is used in the teaching of the utility model, and said chalk sleeve is provided with and is used for the annular groove that matches with pull rope.Annular groove is set on chalk sleeve, can guarantees that chalk contacts with pull rope all the time, the size of being convenient to draw is oval accurately.
Ellipsograph is used in the teaching of the utility model, and said stripe board is provided with is convenient to the Handheld Division that staff holds.The user helps drawing through to the controlling of Handheld Division.
The beneficial effect of the utility model is: the utility model is through being provided with the stripe board of tape guide groove; And setting can be moved in gathering sill and the sliding shoe of location and the pull rope that is connected with sliding shoe; Can draw out effectively different size, true-to-size is oval, help the high efficiency teaching of mathematics more and motivate students' interest in learning.
Description of drawings
Fig. 1 is the structural representation of the teaching of the utility model with ellipsograph;
Structural representation when Fig. 2 matches with chalk for pull rope in the utility model.
Among the figure: 1 stripe board, 2 gathering sills, 3 sliding shoes, 4 pull ropes, 5 chalk sleeves, 6 hold-down screws, 7 Handheld Divisions, 8 annular grooves, 9 chalks.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, provided the structural representation of the teaching of the utility model with ellipsograph, it comprises stripe board 1, two sliding shoes 3, pull rope 4, chalk sleeve 5, hold-down screw 6; Offering gathering sill 2, two sliding shoes 3 that play the guiding role on the stripe board 1 is arranged on the gathering sill 2 movably; Also be provided with scale value on the stripe board 1, so that confirm oval focus.Hold-down screw 6 is arranged on the sliding shoe 3, can sliding shoe 3 be fixed on any position of gathering sill 2 through turn hold-down screw 6.The two ends of pull rope 4 are connected with two sliding shoes 3 respectively, and the length of pull rope 4 is greater than the length of stripe board 1, so that draw out ellipse.Offer the cavity that matches with chalk 9 on the chalk sleeve 5, as shown in Figure 2, the outer surface of chalk sleeve 5 is provided with the annular groove 8 that matches with pull rope 4, so that chalk sleeve 5 can match with pull rope 4 in the process of motion all the time.
In the process of mapping, be initial point with 0 scale on the stripe board 1, phase both sides spacing is liftoff mobile sliding shoe 3, and be located on gathering sill 2 through hold-down screw 6; Then chalk 9 is inserted in the cavity of sliding shoe 3, near the continuous setting-out of the form of pull rope 4, can makes the ellipse of standard with chalk sleeve 5.Through changing the position of sliding shoe 3 on gathering sill 2, can make the ellipse of different size.
