Abstract
The utility model relates to a multi-purpose set square, which comprises a wooden set square body, on which is provided with a level plane angle table and a vertical plane angle table; the vertical plane angle table is composed of a weighted guide finger, a center shaft and a graduated disk, and the level plane angle table is composed of a compass and a graduated disk. Compared with the existing set square, the utility model has the advantages of multi-function, easy use and multiple use; the multi-purpose set square can be used for teaching as well as the architecture construction.
Description
The utility model relates to a kind of teaching multipurpose set square.
In daily education activities, usually use the drawing of on blackboard for education, ruling of wooden set square, use this set square to draw parallel lines, vertical line and when the oblique line that angle requires is arranged, need to cooperate and just can finish with two set squares or graphometer, very inconvenient.
The purpose of this utility model just provides a kind of multipurpose set square, only uses a ruler just can satisfy above-mentioned drawing requirement.
The utility model mainly comprises a wooden triangle blade, on blade, be provided with a horizontal plane angle table and a perpendicular angle table, perpendicular angle table is made of Weight type indicator central shaft and dial, and horizontal plane angle table is made of a compass and dial.When using the utility model on the horizontal plane chart board, to draw, utilize the compass performance, can on the chart board of plane, draw straight line, parallel lines at any angle, and can also use as protractor.When drawing on the blackboard at perpendicular, utilize Weight type pointer in the perpendicular angle table to point to the performance in the earth's core forever, can draw straight line, the parallel lines of various angles, and can use as protractor.Except in teaching, using, can also be used for construction, be used for detection level face, vertical plane, and gradient.
It is many, easy to use that the utility model has function than existing set square, the advantage that a chi is used more.
Followingly describe embodiment of the present utility model in detail with reference to accompanying drawing.
Fig. 1, the utility model schematic diagram.
A concrete enforcement of the present utility model is an isosceles drawing square, blade 1 is wooden, can certainly be plastic products or bamboo product, the base of set square is 500 millimeters long, thick 5 millimeters of blade, to be provided with the pointer 3 of a horizontal plane angle table 2, this table be a compass (being needle) to left part on the blade, and 0 °～360 ° scales are arranged on the dial 4.Right part is provided with a perpendicular angle table 5 on the blade, and this table has a dial 6, is provided with 0 °～360 ° scale.Dial central authorities are provided with central shaft 7, and Weight type pointer 8 is housed on it, and this pointer is a metallic article, and the center of gravity of pointer is at the middle part of pointer, to guarantee when the utility model uses the eternal directed downwards of pointer (being the earth's core) on perpendicular.The dial outside diameter of two angle tables is 80 millimeters.Can set up transparent table illiteracy for making two angle tables in use avoid damaging.
