Abstract

The utility model relates to a laminated multifunction ruler comprising two rulers and a concentric rivet, wherein, one end of every ruler takes the shape of a right angle, the other end takes the shape of a semicircular head with the width of the ruler as the diameter, the central position of the diameter is provided with a circular hole, the one ruler is marked with scale from 0 cm to 15 cm which takes the right angle side as start point, the another ruler is marked with scale from 16 cm to 30 cm which takes the semicircular head as start point, the semicircular heads of the two rulers are connected in laminated way, which are integrated to whole through riveted by a concentric rivet, thereby, the utility model has the functions of ruler, set square, protractor and dividers at the same time, which also has the advantages of simple structure, convenient carrying, reliable working, and strong practicability.

Description

The multi-functional ruler of laminated type

Technical field

The utility model relates to a kind of ruler, and exactly, it is the multi-functional ruler of a kind of laminated type, belongs to the cultural tools field.

Background technology

Nowadays, the ruler that students is used all can only be used for the picture straight line, is set square, has also only increased by one and has drawn leg-of-mutton function.

Summary of the invention

The purpose of this utility model just provides the multi-functional ruler of laminated type a kind of simple in structure, easy to use.

For achieving the above object, the technical scheme that the utility model adopted is:

The multi-functional ruler of a kind of laminated type comprises: 2 ruler and 1 concentric rivet, it is characterized in that:

Described ruler has 2, i.e. ruler 1 and ruler 2, and it is every that an end is a right-angle side long 15 centimetres of ruler, it is the cup head of diameter that the other end is provided with the ruler width, and the diameter center is provided with circular hole; Ruler 1 is that starting point indicates from 0 to 15 centimetre scale to the semicircle head end with the right-angle side, claims the down scale ruler; Ruler 2 is that starting point indicates from 16 to 30 centimetres scale to right-angle side with the semicircle head end, claims the high range ruler; The cup head of ruler 1 and ruler 2 lamination mutually is connected, and through closing-up with one heart, constitutes an integral body.

The utility model is based on two combine into one with 2 rulers, so it can not only be used for the picture straight line, can also be according to corresponding angles principle draw triangle, quadrangle, semicircle and the circle of different shape, the function that has ruler, set square, protractor and compasses simultaneously, and it is simple in structure, easy to carry, reliable operation, characteristics such as practical.
