Description
Technical field
The utility model belongs to art of mathematics, particularly a kind of mathematics teaching aid.
Background technology
Class hour in instructors, in order to the content of course can be told about more intuitively, all use some teaching aids, when especially carrying out several teaching or mathematical education, usually to use ruler, set square and compasses, and at present, these teaching aids are independently individual, the different graphic needing teacher to draw as required during use takes different teaching aids repeatedly, figure simultaneously for some complexity needs multiple teaching aid simultaneously with the use of just drawing out, just be difficult to draw out by means of only teacher one people like this, existing teaching aid uses extremely inconvenience in a word.
Utility model content
For the defect of prior art, the utility model provides a kind of mathematics teaching aid.
A kind of mathematics teaching aid, comprise blackboard body 1, described blackboard body 1 is connected with chassis 8 by two supporting legs 7 bottom it, and described chassis 8 is provided with roller 9; The both sides of described blackboard body 1 are provided with side frame 2, and two side frames 2 offer vertical chute 3, are provided with upright slide block 11 in described vertical chute 3, and described upright slide block 11 is connected with horizontal ruler 10; The top of described blackboard body 1 is provided with top margin frame 4, described top margin frame 4 offers horizontal concrete chute 5, cross sliding clock 12 is provided with in described horizontal concrete chute 5, described cross sliding clock 12 is connected with the first longitudinal ruler 14 by the first rotating shaft 13, and described first longitudinal ruler 14 is connected with the second longitudinal ruler 15 by the second rotating shaft 16; The bottom of described blackboard body 1 is provided with article groove 6.
Optionally, between described two supporting legs 7, bracing piece 17 is provided with.
The beneficial effects of the utility model are: by arranging horizontal ruler, the first longitudinal ruler and the second longitudinal ruler on blackboard, make teacher can draw various mathematics geometric figures in teaching easily, easy to use, flexible.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mathematics teaching aid;
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing, make above-mentioned and other object of the present utility model, Characteristics and advantages will be more clear.Reference numeral identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present utility model is shown.
As shown in Figure 1, mathematics teaching aid of the present utility model comprises blackboard body 1, described blackboard body 1 is connected with chassis 8 by two supporting legs 7 bottom it, described chassis 8 is provided with roller 9, described blackboard body 1 can be moved easily by roller 9, the both sides of described blackboard body 1 are provided with side frame 2, two side frames 2 offer vertical chute 3, upright slide block 11 is provided with in described vertical chute 3, described upright slide block 11 is connected with horizontal ruler 10, slided in vertical chute 3 by upright slide block 11, horizontal ruler 10 in the vertical direction can be made to move, thus horizontal linear can be drawn easily on blackboard, the top of described blackboard body 1 is provided with top margin frame 4, described top margin frame 4 offers horizontal concrete chute 5, cross sliding clock 12 is provided with in described horizontal concrete chute 5, described cross sliding clock 12 is connected with the first longitudinal ruler 14 by the first rotating shaft 13, described first longitudinal ruler 14 is connected with the second longitudinal ruler 15 by the second rotating shaft 16, the bottom of described blackboard body 1 is provided with article groove 6, chalk can be placed in article groove 6, blackboard eraser etc.Described first longitudinal ruler 14 connects and can rotate around the first rotating shaft 13, described second longitudinal ruler 15 can rotate around the second rotating shaft 16, the first longitudinal ruler 14 can be moved by the slip of cross sliding clock 12, the position of the second longitudinal ruler 15, utilize the first longitudinal ruler 14, namely longitudinal straight line can be drawn on blackboard with the second longitudinal ruler 15, oblique line, also the circular arc of different radii can be drawn, such as when the first longitudinal ruler 14, be on same straight line with the second longitudinal ruler 15, and the first longitudinal ruler 14 can draw the maximum circular arc of radius when the first rotating shaft 13 is rotated, then less circular arc or circle can be drawn when the second longitudinal ruler 15 rotates around the second rotating shaft 16.By horizontal ruler 10, first longitudinal ruler 14 and the second longitudinal ruler 15 in the utility model with the use of the various mathematics geometric figures that can draw easily in teaching.Further, between described supporting leg 7, be provided with bracing piece 17, bracing piece 17 can make teaching aid more firm.
Set forth a lot of detail in the above description so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
