Abstract

A folding multifunctional straight ruler comprises a main ruler and an auxiliary ruler. One end of the positive ruler consists of an enlarged angle scale plate, a right-angle reference edge and a concave convex shaft, the convex shaft is movably matched in a hole in the circular arc positioning plate on the side surface of one end of the auxiliary ruler, and the combined positive ruler and the auxiliary ruler can be opened and closed within the range of 0-90 degrees. The angle gauge, the set square and the straight ruler are integrated into a whole, so that the angle gauge can be used as a machining measuring tool, can be used as a drawing tool for technicians and can be used as a study article for primary and middle school students.

Description

Folding multifunction ruler
The utility model belongs to measurer and drawing instrument class.
Traditional drawing instrument, ruler function singleness, angle square volume are greatly, protractor is drawn the angle needs ruler to cooperate, and complicated operation.
The purpose of this utility model is, provides a kind of convertible multi-functional ruler, and it not only can fuse into one traditional ruler, angle square, protractor, but also can make mach measurer angle block gauge, has simple in structure, easy to manufacture, easy and simple to handle.
The utility model is to realize like this, the multi-functional ruler of convertible, constitute by positive chi, secondary chi, positive chi one end is made up of the angle index sheet that enlarges and right angle true edge and recessed protruding axle, protruding axle is movingly in the hole on the circular arc spacer of secondary chi one end side surface, and the axle that matches is with riveted or use the screw spacing hole.Synthetic positive chi and secondary chi can opening and closing in 0~90 ° scope, and constituting at any angle, angle square, protractor, angle block gauge, angle are shown by the groove on angle index limit and the angle index sheet.
The multi-functional ruler of convertible, concave edge on its positive chi one end cooperates with the circular arc spacer of secondary chi one end side surface on the chi face of intersection can carve the oil ga(u)ge scale, the other end can synthesize arbitrarily angled triangle, square, or the circular arc of protractor, chi face when positive chi is merged with secondary chi can also be designed to the protractor groove, and just the true edge of chi one end can be made the plane, makes the secondary chi can opening and closing in 180 °, can also prolong secondary chi, form T square.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the figure of opening of the present utility model.
Fig. 2 is the figure of being merged of the present utility model.
Fig. 3, the 4th, end body figure of the present utility model.
Fig. 5 is that A-A of the present utility model is to profile.
Positive chi (12) among Fig. 1 and secondary chi (2) are for opening shape, the recessed protruding axle (16) of its positive chi (12) one ends is movingly with riveted or with screw control with the hole (17) of secondary chi (2) one ends, make chi limit (13) and the interior angle square of the interior chi limit (14) of secondary chi formation in the positive chi, be protractor, angle block gauge, its number of degrees are shown by the angle index limit (6) on angle index sheet (7) on the positive chi (12) and the secondary chi (2).Complete open positive chi (12) and secondary chi (2) are by the spacing chi that meets at right angles of right angle true edge (8).The true edge of positive chi (12) one ends can be made the plane, makes secondary chi (2) opening and closing in 180 °, can also extend secondary chi (2), and chief and vice chi becomes T square in the time of 90 °.
Fig. 2 is the multi-functional ruler of convertible when being merged, there are ruler scale (1), angle block gauge scale (18) in its surface, protractor graduation mark (15) also can be arranged, can also cooperate the surface design of intersection to become the oil ga(u)ge scale with the circular arc spacer (9) of secondary chi (2) one end side surface at positive chi (12) one end concave edges.The other end is made the right angle body, also can form the angulation body (19) among Fig. 3, can also be processed into any triangle body (20) among the figure (4).
(5) among Fig. 1 are that reinforcement promptly waits flat limit.Room angle (3) on the secondary chi (2) is positioned at secondary chi outward on the line of chi limit (4) vertical central (10) by the round tangentially on chi limit (14) in the secondary chi and the circular arc spacer of widening (9) or from, the summit of room angle (3).Chi limit (13) becomes 90 ° of whole at any angle angle angle squares, angle block gauge, protractor in the positive chi with chi limit (14) in the secondary chi.

Claims (5)

1, the multi-functional ruler of a kind of convertible, constitute by two rulers, scale, numerals, it is characterized in that positive chi (12) one ends are made up of angle index sheet (7) and right angle true edge (8) and recessed protruding axle (16), protruding axle is movingly in (16) hole (17) on secondary chi (2) one end side surface circular arc spacers (9), and the positive chi (12) that matches can opening and closing in 0~90 ° scope with secondary chi (2).
2, multi-functional ruler according to claim 1 is characterized in that the concave edge of positive chi (12) one ends and secondary chi (2) one end side surface circular arc spacers (9) cooperate on the chi face of intersection can be designed to the oil ga(u)ge scale.
3, multi-functional ruler according to claim 1 is characterized in that the ruler surface that positive chi (12) and secondary chi (2) are harmonious can be carved into protractor groove (15).
4, multi-functional ruler according to claim 1 is characterized in that the other end that positive chi (12) links to each other with secondary chi (2) can become the circular arc body (19) of protractor, can also be triangle body (20) arbitrarily.
5, multi-functional ruler according to claim 1 and 2, the right angle true edge (8) that it is characterized in that positive chi (12) one ends can be the plane, it and secondary chi (2) opening and closing in 180 ° scope can also be extended secondary chi (2), and the secondary chi of prolongation and positive chi (12) constitute T square.
