Abstract
The utility model relates to a set square with a compass and a protractor, and belongs to a drawing tool for students. The set square is a right angle set square. One edge of the set square has graduations for measuring lengths, and the other two edges have graduations for measuring angular degrees. The one edge for measuring lengths is additionally provided with a circle center hole, a chute and a moveable slide block which is provided with a round hole and is used as a compass. The utility model has the advantages of raw material saving, convenient use and portability.
Description
The utility model belongs to the student and uses drawing instrument.
Drawing instrument in the past such as set square, protractor and compasses are to make respectively, use separately, therefore use and carry inconvenience.Though have the set square of band protractor to sell on the market, have following shortcoming: because the protractor scale is arranged in the middle of the set square on the semicircular edge, so set square need be done very big.Otherwise when serving as the interval with 1 degree, scale mark is differentiated unclear.
The purpose of this utility model is to overcome above shortcoming, produces a kind of use, easy to carry, has the drawing instrument of set square, protractor and compasses function.
The utility model feature is: the scale that tolerance length is arranged on one side of right angle three plates; The scale mark of tolerance angle is at two edges in addition of set square; On one side of straight set square band width amount length a circular hole as the garden heart is arranged, there is a chute on the circular hole next door, and slidably slide block is housed on chute, has the circular hole of picture circle usefulness on the slide block.
Fig. 2 is a sectional view of deciding pin.
Fig. 1 is the best legend of implementing of the present utility model.
The scale of tolerance length is on the hypotenuse of isosceles right triangle; The scale of tolerance angle is at the edge of two right-angle sides 2; One circular hole 3 as the center of circle is arranged on hypotenuse, and there is chute 4 on circular hole 3 the right, and slide block 7 is housed on the chute, and circular hole 8 is arranged on the slide block 7.
Drawing bowlder, with in the circular hole 3 of certain pin 5 insertions as the center of circle, set square is being fixed earlier.According to drawn radius of circle adjusting slider 7, after mixing up slide block 7 usefulness nuts 6 are fixed, then in the circular hole 8 on the tip of a pencil insertion slide block 7, can the picture circle.
After adopting the utility model, can save material use, easy to carry, economical and practical, durable in use concerning the user.
