Abstract
The utility model relates to a math teaching aid which is formed by a ruler and compasses. Scale lines are arranged on the ruler, the compasses are arranged on one side, opposite to the scale lines, of the ruler, the compasses are formed by a strip-shaped groove, a movable support leg and a fixed support leg, a compasses tip is positioned at the end of the fixed support leg, the movable support leg is formed by installing a support leg on a movable seat, the movable seat is positioned in the strip-shaped groove and in slide connection with the strip-shaped grove, a fixed barrel is arranged at the end of the support leg, and a pencil is inserted in the fixed barrel. The math teaching aid enables the ruler and the compasses to be integrated ingeniously and is convenient to manage and carry.
Description
One, technical field:
The utility model relates to the mathematic(al) construction instrument that uses in mathematical education, mathematical studying and Mathematics Application, what be specifically related to is a kind of teaching apparatus for mathematics.
Two, background technology:
Often to use various mathematic(al) construction instruments in mathematical education, mathematical studying and Mathematics Application, as compasses, ruler etc., existing several common mathematical drawing tool is nearly all independent individuality, substantially all be to solve more single mapping problem, people are when mathematic(al) construction, just to not complete one or both mappings, but to complete multiple mapping, so inner ruler, compasses etc. of often being equipped with simultaneously of people's office bag (school bag), because ruler, compasses etc. is all independent individuality, use bad management, inconvenience.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of teaching apparatus for mathematics, and it is used for solving present several common mathematical drawing tool is all independent individual inconvenient problem with use.
The technical scheme that the utility model adopts is: this teaching apparatus for mathematics is set together by ruler, compasses and consists of, be provided with graduation mark on ruler, a side relative with graduation mark on ruler is provided with compasses, compasses are made of bar-shaped trough, mobile supporting leg, fixed supporting leg, and the end of fixed supporting leg is the compasses points, and mobile supporting leg consists of by supporting leg is installed on Mobile base, Mobile base is arranged in bar-shaped trough, and be slidably connected with bar-shaped trough, the end of supporting leg is stationary magazine creel, pencil is inserted in stationary magazine creel.
In such scheme, ruler is folding, ruler is divided into two along its length, form rule section and compasses sections, rule section and compasses sections are movably connected by little axle, and rule section and compasses sections may be folded on together, when both folding, the reduced width of ruler is original half, at this moment, and when using compasses, convenient, draw bowlder and easily control.
Beneficial effect:
1, the utility model is designed to one dexterously with ruler, compasses, is convenient to management, easy to carry.
2, the utility model is simple in structure, and applicability is strong.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model.
1 ruler 2 bar-shaped troughs 3 move supporting leg 4 fixed supporting leg 5 Mobile base 6 graduation marks.
Five, the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, this teaching apparatus for mathematics is set together by ruler 1, compasses and consists of, be provided with graduation mark 6 on ruler 1, a side relative with graduation mark on ruler 1 is provided with compasses, and compasses are made of bar-shaped trough 2, mobile supporting leg 3, fixed supporting leg 4, the end of fixed supporting leg 4 is compasses points, mobile supporting leg 3 consists of by supporting leg is installed on Mobile base 5, and Mobile base 5 is arranged in bar-shaped trough 2, is slidably connected with bar-shaped trough 2, the end of supporting leg is stationary magazine creel, and pencil is inserted in stationary magazine creel.
During use, the large young pathbreaker of the circle of drawing as required moves supporting leg 3 and slides into corresponding position, due to the side of compasses design at ruler, can see mobile supporting leg 3, fixed supporting leg 4, can easily mobile supporting leg 3 be slided into the position that needs, when choosing the position of mobile supporting leg 3, fixed supporting leg 4 be scheduled a bit, rotary ruler combination 1 just can draw the circle that needs.
