Abstract
The utility model provides a multifunctional ruler. It includes a ruler and a set square, the ruler includes a long scale limit that has a length groove and one the parallel long limit that does not have the groove with it, the set square includes one 45 jiaos, one 30 jiaos and one 105 jiaos, the long limit of ruler and set square 105 jiaos through spout slider mechanism swing joint between the right limit. The utility model discloses combine ruler and set square together betterly to can not have seam ground and draw no limit for length's straight line, convenient to use, convenient to detach carries.
Description
Technical field
The utility model relates to a kind of tool ruler charted, especially a kind of multipurpose ruler.
Background technology
In work such as study geometry, machine design drawing etc., ruler is one of most important instrument.The conventional reason of ruler because carrying, what length can not make is very long, and the length of conventional ruler is generally between 15cm ~ 20cm.When picture is greater than the long line of 20cm, now conventional ruler operates very inconvenient.
Summary of the invention
In order to overcome existing ruler awkward deficiency when drawing the longer straight line of length, the utility model provides a kind of multipurpose ruler, and this chi jointlessly can draw the straight line of endless, and can draw the plurality of lines such as circle, camber line, vertical line, parallel lines very easily.
The technical scheme that the utility model solves the employing of its technical problem is: comprise a ruler and a set square, described ruler comprises the long long limit that do not have groove parallel with it with the scale limit of length groove, described set square comprises a 45° angle, 30 ° of angles and 105 ° of angles, is flexibly connected between the limit that the long limit of described ruler is right with 105 ° of angles of set square by chute slide block mechanism.
Compare existing ruler, a kind of multipurpose ruler of the present utility model, that ruler and set square are flexibly connected, can relative movement between ruler and set square, ruler is put well, again set square is placed on ruler, if the line drawn exceeds ruler length, then fixed triangle plate is by the direction slip ruler of line, if still fallen short of, then pin ruler more motionless, by the direction slip set square of line make its again with ruler all or major part overlap, then can fixed triangle plate again, mobile ruler continues line, repeat aforesaid operations, until line terminates, the straight line of endless can be drawn like this, and there is no seam.In addition, ruler and set square can individually use, and after taking apart, storage is carried more convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the use procedure schematic diagram of the utility model one embodiment.
In figure, 1, protractor, 2, ruler, 3, set square, 4, right angle, 5, arc-shaped side, 6,45 degree of hypotenuses, 7, radius hole, 8, radian groove, 9,30 degree of hypotenuses, 10, chute slide block mechanism, 11, pin joint.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Fig. 1 and Fig. 2 shows the structural representation of the utility model preferred embodiment, a kind of multipurpose ruler in figure, comprise a ruler 2 and a set square 3, described ruler 2 comprises the long long limit that do not have groove parallel with it with the scale limit of length groove, described set square 3 comprises a 45° angle, 30 ° of angles and 105 ° of angles, is flexibly connected between the limit that the long limit of described ruler 2 is right with 105 ° of angles of set square 3 by chute slide block mechanism 10; Chute can be offered on the long limit of ruler 2, the long limit of the through ruler of chute 2, arrange on the limit that 105 ° of angles of set square 3 are right and slide block that chute is suitable simultaneously; Slide block can also be set on the long limit of ruler 2, and suitable chute is set on the limit that 105 ° of angles of set square 3 are right.
Be that described set square 3 has the protractor 1 of a hollow on chi face as further improvement of this embodiment scheme, the angle that the arc-shaped side 5 of protractor 1 is right is right angle 4.Now, set square part has 45 degree of hypotenuses 6, right-angle side and 30 degree of hypotenuses 9 can draw right angle, miter angle, 30 degree, 60 degree angles easily, and pinning the motionless slip set square of ruler 2 can draw parallel lines.Protractor 1 can take measurement of an angle, and being greater than an angle of 90 degrees will survey twice.
As improving further again of the present embodiment be, described set square 3 also has a pin joint 11 on chi face, the blade of set square 3 rotates around this pin joint 11, at a distance of pin joint 11 certain distance, several radius holes 7 are set, such as offer and the radius hole 7 of pin joint 11 at a distance of 10,20,30,40,50,15,25,35,12.5,17.5,22.5 (mm), can arrange in the manner shown in figure 1, the chi face of the circumference of pin joint 11 is provided with radian groove 8.Use pin joint 11, radius hole 7 and radian groove 8 can draw circle and camber line.Penholder is entered in corresponding radius hole 7 and rotate around pin joint 11 (i.e. the center of circle) button, circle and camber line can be drawn.
Improve further, described set square 3 is provided with length groove on the right limit in the right limit of 45° angle or 30 ° of angles again.Add and measure limit.
Further, the 45° angle of described set square 3 is the short vertical edge parallel with the side of ruler 2 with 30 ° of angles place.Really can slip better like this, not easily depart from when ruler 2 and set square 3 relative sliding.
Fig. 2 shows the operating process that a kind of multipurpose ruler of the utility model draws straight line: first ruler 2 is put well, again set square is placed on ruler 2, if the line drawn exceeds ruler length, then fixed triangle plate (rules direction as shown by arrows by the direction of line, line direction is the direction of ruler movement) slip ruler 2, if still fallen short of, then pin ruler 2 more motionless, by the direction slip set square of line make its again with ruler 2 all or major part overlap, then can fixed triangle plate again, mobile ruler 2 continues line, repeat aforesaid operations, until line terminates.
The above; be only preferred embodiment of the present utility model, not any pro forma restriction done to the utility model, every according to technical spirit of the present utility model; to any simple modification done by above embodiment and equal change, all fall within protection domain of the present utility model.
