Description

A kind of middle school mathematics board of education
Technical field
The utility model relates to a kind of middle school mathematics boards of education.
Background technique
Currently, being frequently necessary on blackboard carry out demonstration explanation by drawing during the mathematical education in middle school, especially It needs clearly could intuitively express by drawing functional image when being related to function problem, but present mathematics The main plotting mode of teacher is using drawing manually, and teacher holds ruler and chalk is drawn repeatedly on blackboard, is operated in this way It is cumbersome, it is time-consuming and laborious, work difficulty is increased to teacher, moreover, teacher is when drawing functional image, due to not having Auxiliary tool and referring to figure, just will form biggish error, cause the image drawn inaccurate, figure is nonstandard, thus Influence teaching efficiency.In addition, teacher will lift ruler on the other hand when traditional simple manual drawing, chalk is held on the other hand, sometimes one Class, which gets off, will also draw more than one functional arrangement, this to teacher increase many workloads and teaching efficiency receive it is little, Also teaching efficiency can be reduced.
Utility model content
In view of this, the utility model aim is to provide, one kind is structurally reasonable, can be reduced teacher's Plot Work amount, user Just, easy to operate, it was not only able to achieve the writing and explanation of the content of courses, but also can simply and easily draw functional image, and can accomplish to draw Figure is convenient, expresses clearly intuitive middle-school mathematics teaching plate.
In order to solve the above-mentioned technical problem, the technical solution of the use of the new type is:
A kind of middle school mathematics board of education, including sheet frame, and sheet frame two sides, more than one hook are set, it is described Blank board of education and function demonstration board are equipped in sheet frame, the function demonstration board is equipped with reference axis with a scale and peripheral side Equipped with slide-and-guide bar, the slide-and-guide bar installation is provided with circle on the slide-and-guide bar on the interior avris of sheet frame Protractor, the circle protractor packet expansion have loop bar, angle deviding instrument and angulation bar, and the angle deviding instrument is fixed on loop bar On, the angulation bar is mounted on angle deviding instrument, and the angle deviding instrument is one non-rotatable, with angle deviding instrument Circular disk body.
Preferably, the angle deviding instrument includes that a chassis mutually welded with loop bar and one are fixed on chassis Bearing.
Preferably, the angle deviding instrument is located at the surface on chassis, the perimeter on the chassis is greater than the perimeter of turntable, institute State angulation bar be welded in turntable peripheral side and be overlapped at 90 scales of angle deviding instrument.
Preferably, the slide-and-guide bar is equipped with two and is located at the upside and left side of sheet frame.
Preferably, the hook is arranged in " J " word shape and divides equally in the two sides of sheet frame.
The utility model has the technical effect that following aspect: being divided into hollow plate and letter by the way that sheet frame is divided into board of education Number demonstration board can be realized text teaching by board of education and said content is passed through function more by function demonstration board Intuitively express;It is also equipped with round protractor simultaneously, by loop bar in the socket of slide-and-guide bar, Lai Shixian angle point The movement for spending instrument and angulation bar realizes the rotation of angle deviding instrument and angulation bar by bearing, to reach the effect for facilitating drafting Fruit.
Detailed description of the invention
Fig. 1 is a kind of middle school mathematics structure of teaching schematic diagram of the utility model;
Fig. 2 is a kind of side view of the round protractor of middle school mathematics board of education of the utility model;
Fig. 3 is a kind of structure chart of the round protractor of middle school mathematics board of education of the utility model.
Specific embodiment
In conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model technical side Case is more readily understood and grasps.
Refering to fig. 1 shown in -3, a kind of middle school mathematics board of education, including sheet frame 1, and be arranged in sheet frame two sides, one Above hook 7, can be used for hanging the educational aids such as set square, compasses;Blank board of education 3 and function are equipped in the sheet frame 1 Demonstration board 4, teacher can write the content of courses in blank board of education 3, can drilling in the enterprising line function image of function demonstration board 4 Show, the function demonstration board 4 is equipped with reference axis 41 with a scale and peripheral side is equipped with slide-and-guide bar 6, the slide-and-guide With on the interior avris of sheet frame 1, slide-and-guide bar 6 has two and is mutually perpendicular to the installation of bar 6, is provided with circle on the slide-and-guide bar Shape protractor 5 there are two round protractor 5 is set, is located at the top and left side of function demonstration board 4, the circle protractor 5 It include loop bar 53, angle deviding instrument and angulation bar 51, round protractor 5 is by 53 sets of loop bar on slide-and-guide bar 6 and energy It is moved on slide-and-guide bar 6, the angle deviding instrument 57 is fixed on loop bar 53, and the angulation bar 51 is mounted on angle-differentiated On instrument, angle deviding instrument 57, turntable 55 and angulation bar 51 are used cooperatively, and can simply and easily draw functional image, the angle Degree protractor 57 is a circular disk body non-rotatable, with angle deviding instrument 54, and the angle deviding instrument 57 includes one It is fixed on the bearing 52 on chassis 56 with the chassis 56 of 53 phase of loop bar welding and one, turntable 55 can be made circumferentially to rotate, The angle deviding instrument 54 is located at the surface on chassis 56, and the perimeter on the chassis 56 is greater than the perimeter of turntable 55, the angulation bar 51 be welded in the peripheral side of turntable and be overlapped at 90 scales of angle deviding instrument 54.
