Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of board of education facilitating math teacher to impart knowledge to students.
Background technology
At present, needs frequent in mathematical education process are mapped and are explained demonstration on blackboard, ruler for drawing of the prior art mainly by teacher at school time band entering classrooms, such operation extremely bothers, teaching notes not only will be with upper class hour also will to be with mapping ruler, sometimes also have homework book or paper, this adds trouble to teacher beyond doubt; And existing tabular chi is when drafting horizontal line or parallel lines, owing to not having object of reference, the horizontal line thus drawn out or parallel lines all and nonstandard, draw poor effect.
Summary of the invention
The purpose of this utility model is to provide a kind of board of education facilitating math teacher to impart knowledge to students, which overcome deficiency of the prior art, math teacher at school time, ruler for drawing need not be carried again, the ruler that board of education can be utilized to carry is drawn, and this ruler for drawing can easily draw out parallel lines and horizontal line.
For realizing above-mentioned utility model object, the technical scheme that the utility model adopts is: a kind of board of education facilitating math teacher to impart knowledge to students, comprise blackboard, also comprise ruler for drawing, described ruler for drawing is slidably connected at the lower limb of blackboard by connecting rod, described ruler for drawing is hinged on one end of connecting rod, the other end of described connecting rod is hinged with roller, the bottom of described blackboard is provided with the chute guide rail being parallel to its lower limb, and the lower limb of blackboard and chute guide rail are in same level, distance between the lower limb of described blackboard and chute guide rail is 1-3cm, described roller can be free to slide along chute guide rail.
Further, the distance between the lower limb of described blackboard and chute guide rail is 2cm.
Further, the middle part of described ruler for drawing is hinged on one end of connecting rod.
Further, described ruler for drawing is provided with level meter, and this level meter is parallel with the length direction of ruler for drawing.
The utility model has following beneficial effect:
(1) ruler for drawing of the present utility model is slidably connected at the lower limb of blackboard by connecting rod, described ruler for drawing is hinged on one end of connecting rod, the other end of described connecting rod is hinged with roller, the bottom of described blackboard is provided with the chute guide rail being parallel to its lower limb, and the lower limb of blackboard and chute guide rail are in same level, described roller can be free to slide along chute guide rail; Such math teacher at school time not be used in and carry ruler for drawing, the ruler for drawing that direct utilization is slidably connected at blackboard lower limb can be mapped, because roller can be free to slide along chute guide rail, can be able to map in the whole length range of blackboard, and be hinged on one end of connecting rod due to ruler for drawing, the other end of connecting rod is hinged with roller, namely ruler for drawing can draw the straight line of any direction, and when not needing mapping, ruler for drawing can also be received and chute guide rail parallel, not affect the use of blackboard;
(2) distance between blackboard lower limb of the present utility model and chute guide rail is 1-3cm, there is such distance, and chalk dust can be avoided to enter, in chute guide rail, to affect the use of ruler for drawing;
(3) due to ruler for drawing being provided with level meter, when drawing horizontal line or parallel lines, by the water column in eye-level instrument, ruler for drawing can be adjusted to level, horizontal line and parallel lines can easily be drawn out.

Fig. 1 be when drawing in the utility model embodiment connecting rod perpendicular to view during chute guide rail;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is another view of the present utility model;
Fig. 4 is the view that in the utility model embodiment, ruler for drawing is packed up.
In figure: 1, blackboard; 2, ruler for drawing; 3, connecting rod; 4, roller; 5, chute guide rail; 6, level meter; 7, fixed bar.
Detailed description of the invention
As shown in Figures 1 to 4:
A kind of board of education facilitating math teacher to impart knowledge to students, comprise blackboard 1, also comprise ruler for drawing 2, described ruler for drawing 2 is slidably connected at the lower limb of blackboard 1 by connecting rod 3, the middle part of described ruler for drawing 2 is hinged on one end of connecting rod 3, the other end of described connecting rod 3 is hinged with roller 4, the bottom of described blackboard 1 is provided with the chute guide rail 5 being parallel to its lower limb, and the lower limb of blackboard 1 and chute guide rail 5 are in same level, distance between the lower limb of described blackboard 1 and chute guide rail 5 is 2m, and described roller 4 can be free to slide along chute guide rail 5.Such math teacher at school time not be used in and carry ruler for drawing 2, the ruler for drawing 2 that direct utilization is slidably connected at blackboard 1 lower limb can be mapped, because roller 4 can be free to slide along chute guide rail 5, can be able to map in the whole length range of blackboard 1, and be hinged on one end of connecting rod 3 due to ruler for drawing 2, the other end of connecting rod 3 is hinged with roller 4, namely ruler for drawing 2 can draw the straight line of any direction, and when not needing mapping, ruler for drawing 2 can also be received parallel with chute guide rail 5, not affect the use of blackboard 1.
Described ruler for drawing 2 is provided with level meter 6, this level meter 6 is parallel with the length direction of ruler for drawing 2, due to ruler for drawing 2 being provided with level meter 6, when drawing horizontal line or parallel lines, by the water column in eye-level instrument 6, ruler for drawing 2 can be adjusted to level, horizontal line and parallel lines can easily be drawn out.
