Abstract

The utility model relates to a multi-function adjustable angle square, which has the technical characteristic that the angle square whose top is provided with two circular graduation discs is composed of two straightedges. The body of the angle square is provided with a level meter, a blade, a pen nib, and the end of the angle square is provided with scribing compasses. Capable of measuring various changeable angles, measuring the length and the level, the angle square has multiple functions, and is very convenient and suitable for electromechanical mounting, building construction, machining manufacture, drawing, blanking, angle measurement and positioning, etc.

Description

Multi-function adjustable angle square

The utility model belongs to the amount of painting instrument.

In operations such as machining, dynamo-electric installation, civil engineering, the workpiece that usually runs into different shape need be to angular surveying, location, blanking, picture, the present bevel protractor that uses, commercially available an angle of 90 degrees chi and the homemade special-purpose angle square of each applying unit are arranged, their characteristics are fixed angles, so it is the scope of application is limited,, very inconvenient for measuring irregular angle.

The purpose of this utility model provides a kind of adjustable angle square, and the various angles of its energy measurement object are measured length, level, can draw the garden, and multiple function is arranged.

The technical solution of the utility model is: a kind of multifunctional movable angle square, constitute by last ruler and following ruler, it is characterized in that: go up the circle that there is a band circle center hole ruler end, circumference indicates angle, and there is the disk of a tape spool bar following ruler end, and disk is marked with angle, this axostylus axostyle places in the circle center hole of ruler, this disk focuses in the circle of ruler, and " O " point of two circles is corresponding, and " O " point is positioned at parallel with the ruler limit and passes through on the straight line in the center of circle.

The adjustable angle square of present technique can have the chi point of doing the usefulness of planing in the opposite end on top, angle.

The adjustable angle square of present technique can be equipped with level meter on blade.

The adjustable angle square of present technique can be equipped with blade on blade.

Because two limit opening and closing arbitrarily of adjustable angle square, so can measure any angle at workpiece interior angle and exterior angle, angle value directly is presented on the disk on top, angle simultaneously, and this can be accurate to each degree than with fixedly angle square and special-purpose angle square are easy to use.Two limits of adjustable angle square are two rulers simultaneously.But the levelness and the perpendicularity of the level meter measuring workpieces of installing on the blade of ruler.The blade of installing on the blade can be used to the secant head, sharpens a pencil, and adjustable angle square has multiple function, uses flexible, convenient.

Below in conjunction with accompanying drawing an embodiment of the present utility model is described.

Fig. 1 is the structural representation of the utility model multifunctional movable angle square.

Fig. 2 is the side cutaway view of Fig. 1.

It is pointed going up chi (1) one end among the figure, and blade has the ruler scale, and clock dial (2) is arranged on the other end, and circle center hole (3) is arranged on the clock dial.Following chi (6) is corresponding with last chi (1), the clock dial (4) of following chi (6) is connected with following chi by axostylus axostyle (5), this axostylus axostyle (5) is contained in the circular hole (3) of chi, two clock dials are overlapped, and " O " point of its two clock dial is positioned at the parallel rule limit, and by on the straight line in the center of circle, each scale of the circular scale of last chi is represented 10 degree, 360 degree were arranged in one week, be divided into 10 equal portions in the roundlet dial per quart circle of following chi, each equal portions is represented 1 degree.During use, two chis open, and roundel " O " scale is 10 place readings of tested angle facing to the reading on the big disk, and when the graduation mark of roundel was on a line greatly, the roundel scale on this line was the units reading of tested angle.The level meter (10) of surveying levelness and the level meter (11) of surveying perpendicularity also are housed on the blade of last chi (1), this blade of blade (8) also are housed on the blade of last chi (1) can fold in the tool magazine (7).Present embodiment also is equipped with a storehouse (9) on the blade of last chi (1).

Claims (5)

1, a kind of multifunctional movable angle square, constitute by last ruler and following ruler, it is characterized in that: go up the circle that there is a band circle center hole ruler end, circumference indicates angle, and there is the disk of a tape spool bar following ruler end, and disk is marked with angle, this axostylus axostyle places in the circle center hole of ruler, this disk focuses in the circle of ruler, and " O " point of two circles is corresponding, and " O " point is positioned at parallel with the ruler limit and passes through on the straight line in the center of circle.
