Abstract

The utility model provides a multifunctional set square which comprises a first side, a second side and a third side. One end of the first side is connected with one end of the second side through a first rotating shaft, the other end of the first side is connected with one end of the third side through a second rotating shaft, a through groove is arranged on the end portion of the other end of the second side and the side edge, facing the first side, of the second side, the other end of the third side is inserted into the through groove to form a triangle structure, and the second side and the third side are telescopic rods. The set square can be adjusted into set squares of various structures, and also disassembled and used as a ruler.

Description

A kind of multifunctional triangle

Technical field

The utility model belongs to educational aid, relates to a kind of multifunctional triangle.

Background technology

Set square is one of educational aid of commonly using, and present set square structure is more single, all is single right angle triangle or equilateral triangle plate generally, has brought inconvenience to classroom instruction, has affected to a certain extent efficiency of teaching.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of the utility model device is to provide a kind of multifunctional triangle, can adjust the set square as various structures, and can take apart as ruler and use, and has characteristics easy to use simple in structure.

To achieve these goals, the technical scheme of the utility model device employing is:

A kind of multifunctional triangle, comprise first side 1, Second Edge 2 and the 3rd limit 3, one end of first side 1 is connected with an end of Second Edge 2 by the first rotating shaft 4, the other end of first side 1 is connected with an end on the 3rd limit 3 by the second rotating shaft 5, the other end end of Second Edge 2 and insert in the groove 6 towards the other end that the side of first side 1 has groove 6, the three limits 3 and to consist of triangular structure.

Wherein, described Second Edge 2 and the 3rd limit 3 are preferably expansion link.

Compared with prior art, the utility model can be adjusted the set square as various structures, and can take apart as ruler and use.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the structural representation of the groove opened of the utility model Second Edge end and side direction.

The specific embodiment

Below in conjunction with accompanying drawing and example the utility model device is described in further details.

As shown in Figure 1, the utility model is a kind of multifunctional triangle, comprise first side 1, Second Edge 2 and the 3rd limit 3, an end of first side 1 is connected with an end of Second Edge 2 by the first rotating shaft 4, and the other end of first side 1 is connected with an end on the 3rd limit 3 by the second rotating shaft 5.

As shown in Figure 2, the other end end of Second Edge 2 and have groove 6, the three limits 3 and Second Edge 2 is expansion link towards the side of first side 1, its other end is thinner with respect to an end that is connected with first side 1, also can make special connector, consist of triangular structure in the insertion groove 6.

When the 3rd limit 3 is taken out from groove 6, first side 1, Second Edge 2 and the 3rd limit 3 are pulled into straight line, then can be used as ruler and use.

When the length of the 3rd limit 3 and Second Edge 2 is adjusted, all with first side 1 equal in length, then consisted of equilateral triangle.

Adjust when the length of the 3rd limit 3 and Second Edge 2 being carried out other, then can consist of the triangle of other structure, such as isosceles right triangle etc.

Claims

1. multifunctional triangle, comprise first side (1), Second Edge (2) and the 3rd limit (3), it is characterized in that, one end of first side (1) is connected with an end of Second Edge (2) by the first rotating shaft (4), the other end of first side (1) is connected with an end of the 3rd limit (3) by the second rotating shaft (5), the other end end of Second Edge (2) and have groove (6) towards the side of first side (1), the other end on the 3rd limit (3) inserts and consists of triangular structure in the groove (6), and described Second Edge (2) and the 3rd limit (3) are expansion link.
