Abstract

The utility model relates to a multifunctional geometric ruler for drawing, which is mainly composed of a main ruler (1) and an accessory ruler (3) and is characterized in that the main ruler (1) is in scarf joint with a sliding block (6) which can travel on a guide track (7) of the main ruler (1), the accessory ruler (3) is hinged with the sliding block (6) through a shaft (4) and can be rotated around the shaft (4), the hinged end of the accessory ruler (3) is provided with an angle pointer (5), and the surface of the sliding block (6) is provided with an angle disc. The utility model integrates the functions of general drawing tools such as a triangular ruler, a T-ruler, a protractor, etc. in one, having the advantages of simple structure and easy use.

Description

Multifunction geometric ruler

The utility model relates to the multi-functional dimensioning of a kind of drawing.

In the prior art, normally used drawing instrument has set square, T-square, protractor etc., generally all will simultaneously these drawing instruments be used and just can finish drawing, so just has inconvenient and the ineffective problem used.

The purpose of this utility model is to provide a kind of multi-functional dimensioning that integrates the function of drawing instruments commonly used such as set square, T-square and protractor.

The utility model mainly is made up of a main scale (1) and a pair chi (3), it is characterized in that main scale (1) and slide block (6) tabling, and slide block (6) can be gone up at the guide rail (7) of main scale (1) and move; It is hinged by axostylus axostyle (4) and slide block (6) to pay chi (3), pays chi (3) and can rotate around axostylus axostyle (4); The hinged end of paying chi (3) has angle indicator (5), and there is angle scale on the surface of slide block (6).

Advantage of the present utility model is: multi-functional dimensioning integrates the function of drawing instruments commonly used such as set square, T-square and protractor; Simple in structure, easy to use.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model side cutaway view.

The utility model is further specified as follows below in conjunction with accompanying drawing: as depicted in figs. 1 and 2, the utility model mainly is made up of main scale (1) and attached chi (3), main scale (1) and slide block (6) tabling, slide block (6) can be gone up at the guide rail (7) of main scale (1) and move; It is hinged by axostylus axostyle (4) and slide block (6) to pay chi (3), and fixing by nut (2), pays chi (3) and can rotate around axostylus axostyle (4); The hinged end of paying chi (3) has angle indicator (5); Angle scale is carved with on the surface of slide block (6); On main scale (1) and pair chi (3), be carved with scale value respectively.

Claims

1, a kind of multi-functional dimensioning, mainly form by a main scale (1) and a pair chi (3), it is characterized in that main scale (1) and slide block (6) tabling, slide block (6) can be gone up at the guide rail (7) of main scale (1) and move, it is hinged by axostylus axostyle (4) and slide block (6) to pay chi (3), paying chi (3) can rotate around axostylus axostyle (4), and the hinged end of paying chi (3) has angle indicator (5), and angle scale is carved with on the surface of slide block (6).

2, according to right ask 1 described multi-functional dimensioning, it is characterized in that described main scale (1) and pay on the chi (3) being carved with scale and scale value respectively.
