Abstract

The utility model discloses a multifunctional teaching aid, which is characterized in that: a commonly used folding ruler and a compass are integrated organically together through a fixed shaft, and the other surface of the compass is excavated two slots. The inners of the two slots are equipped respectively with a fixed shaft, so that the tip of the compass can move up and down. When the tip of the compass is down, the two legs of the compass are spread out and the folding ruler is straightened, the teaching aid has the use functions of a ruler and a triangle. Because the structure is adopted, the teaching aid has multi functions, and the carrying and use are both very convenient.

Description

Multi-functional teaching aid

The utility model relates to the teaching aid that a kind of teacher uses, and is particularly a kind of multi-functional and carry, use all teaching aid very easily.

At present, ruler, circle rail, set square are mathematics teacher's mapping instruments commonly used at school the time.Therefore, the teacher before class just must get these three kinds of teaching aids earlier ready.In when mapping, be everlasting use up a kind of teaching aid after, get another kind of teaching aid again and use, carry like this and use all inconvenient.

The purpose of this utility model is exactly that a kind of function of designing at this phenomenon is many and use and carry all teaching aid very easily.

The purpose of this utility model is achieved in that the two ends of folding rule 1 commonly used, combines by 2 stationary shaft 3 and round rail 2 commonly used, and the two ends of folding rule can freely be rotated by stationary shaft 3, as Fig. 1.On the another side of circle rail 2, excavate two strias 5 (size of groove is advisable to put round rail point 4 into) again.A stationary shaft 6 is installed in these two grooves 5 respectively, and it is up and down to make round rail point 4 pass through stationary shaft 6.When circle rail point 4 down the time, just in time put groove 5 into, as Fig. 2.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 folding rule and the figure that combines that justifies rail

The up and down synoptic diagram of Fig. 2 circle rail point

This teaching aid of Fig. 3 has the functions of use synoptic diagram of ruler, set square.

Among Fig. 1: 1, the stationary shaft 4 of folding rule 2, circle rail 3, circle rail and folding rule, circle rail point

Among Fig. 2: 5, justify the pickup groove 6 on the rail two legs, the up and down stationary shaft of round rail point

This teaching aid, opens the two legs of round rail 2 circle rail point 4 up in use, and this teaching aid is when the use of circle rail.Circle rail point 4 is put into groove 5 down, open the two legs of round rail 2, stretching folding rule 1 just can be worked as ruler or set square and use, as Fig. 3.Like this, a kind of teaching aid is served many purposes, and carry and use all very convenient.

Claims

1, a kind of multi-functional teaching aid.It is characterized in that: the two ends of folding rule commonly used in the teaching organically are combined into as a whole by stationary shaft and compasses commonly used, allow the lower parallel of folding rule and compasses, and make folding rule can pass through stationary shaft freely to rotate.
