Abstract
The utility model provides a teaching blackboard with a horizontal coordinatometer and a vertical coordinatometer. The teaching blackboard solves the problems that an existing teaching blackboard has no coordinate axes, so that drawn figures have large errors, the coordinate axes are not standard in shape, and teaching effect is affected. The upper end and the lower end of a blackboard main body are respectively provided with a horizontal guide rail along the length direction, each horizontal guide rail is provided with a first slide block in a sleeved mode, and the vertical coordinatometer is connected with the two horizontal guide rails through the two first slide blocks in a sliding mode. The left end and the right end of the blackboard main body are respectively provided with a vertical guide rail in the vertical direction, and each vertical guide rail is provided with a second slide block in a sleeved mode. The horizontal coordinatometer is connected with the two vertical guide rails through the two second slide blocks in a sliding mode. The horizontal coordinatometer is attached to the front end face of the blackboard main body, and the vertical coordinatometer and the horizontal coordinatometer are arranged in a perpendicular intersection mode. The teaching blackboard is used for drawing coordinate axes.
Description
Technical field
The utility model relates to a kind of blackboard for education, is specifically related to a kind of blackboard for education that has horizontal ordinate chi.
Background technology
At present, in College Mathematics Teaching, the teacher need be on blackboard graphing or function curve etc., existing blackboard for education does not have reference axis, has increased teacher's the drawing time, and there is bigger error in the figure of drawing, the reference axis shape is nonstandard, influences teaching efficiency.
The utility model content
The utility model does not have reference axis for solving existing blackboard for education, and there is bigger error in the figure that causes drawing, and the reference axis shape is nonstandard, influences the problem of teaching efficiency, and then a kind of blackboard for education that has horizontal ordinate chi is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the blackboard for education that has horizontal ordinate chi of the present utility model comprises the blackboard main body, described blackboard for education also comprises lateral coordinates chi, along slope coordinate chi, two first slide blocks, two second slide blocks, two cross slide waies and two longitudinal rails, a cross slide way respectively is installed on the upper and lower side of blackboard main body along its length, be set with first slide block on each cross slide way, the along slope coordinate chi is slidingly connected by two first slide blocks and two cross slide waies; Side upper edge, the left and right sides vertical direction of blackboard main body respectively is equipped with a longitudinal rail, be set with second slide block on each longitudinal rail, the lateral coordinates chi is slidingly connected by two second slide blocks and two longitudinal rails, the front end face of lateral coordinates chi and blackboard main body is sticked mutually and puts, the setting that intersects vertically of along slope coordinate chi and lateral coordinates chi.
The beneficial effects of the utility model are: the blackboard for education that has horizontal ordinate chi of the present utility model is provided with lateral coordinates chi and along slope coordinate chi, when drawing, the teacher can use lateral coordinates chi and along slope coordinate chi to draw reference axis, compare with existing blackboard for education, the reference axis shape criteria of drawing has improved teaching efficiency greatly.
Description of drawings
Fig. 1 front view that has the blackboard for education of horizontal ordinate chi of the present utility model.
The specific embodiment
The specific embodiment one: as shown in Figure 1, the blackboard for education that has horizontal ordinate chi of present embodiment comprises blackboard main body 1, described blackboard for education also comprises lateral coordinates chi 2, along slope coordinate chi 3, two first slide blocks 4, two second slide blocks 5, two cross slide waies 6 and two longitudinal rails 7, a cross slide way 6 respectively is installed on the upper and lower side of blackboard main body 1 along its length, be set with first slide block 4 on each cross slide way 6, along slope coordinate chi 3 is slidingly connected by two first slide blocks 4 and two cross slide waies 6; Side upper edge, the left and right sides vertical direction of blackboard main body 1 respectively is equipped with a longitudinal rail 7, be set with second slide block 5 on each longitudinal rail 7, lateral coordinates chi 2 is slidingly connected by two second slide blocks 5 and two longitudinal rails 7, the front end face of lateral coordinates chi 2 and blackboard main body 1 is sticked mutually and puts, the setting that intersects vertically of along slope coordinate chi 3 and lateral coordinates chi 2.
During use, lateral coordinates chi 2 and along slope coordinate chi 3 are adjusted to suitable position, transversely coordinatometer 2 and along slope coordinate chi 3 drafting reference axis get final product then.
The specific embodiment two: as shown in Figure 1, all be carved with scale on present embodiment lateral coordinates chi 2 and the along slope coordinate chi 3.So design is convenient to draw reference axis.Other composition and connected mode are identical with the specific embodiment one.
