Abstract
The utility model discloses a novel folding rectangular protractor. The novel folding rectangular protractor comprises a main triangular rule, a movable triangular rule and a connecting device for the main triangular rule and the movable triangular rule; the main triangular rule is an isosceles right triangular rule; the bevel edge of the main triangular rule is connected with one side of the movable triangular rule through the arranged connecting device; the movable triangular rule can rotate by taking the bevel edge of the main triangular rule as a shaft. During use, according to concrete requirements on drawing, the movable triangular rule is rotated and is enabled to be positioned in the same plane as the main triangular rule, and at the moment, a triangular rule of which one bevel edge is two times a certain right-angle side can be obtained; when the movable triangular rule is rotated to be superposed with the main triangular rule, an isosceles right triangular rule and a triangular rule of which one smaller bevel edge is two times a certain right-angle side can be obtained.
Description
Affiliated technical field
The utility model relates to a kind of novel folding dimensioning, belongs to a kind of dimensioning.
Background technology
At present, dimensional measurement instrument miscellaneous, greatly facilitates people mapping and study, but the most frequently used or two set squares and a protractor while usually mapping.Like this, owing to being separated each other, also brought many inconvenience to user, also easily lose.Therefore, concerning people, also lack that a kind of that two set squares and protractor are combined into a function is more, use more conveniently, meet the novel dimensioning of multiple different demands.
Summary of the invention
In order to overcome above-mentioned existing two set squares and the protractor of conventionally need to using, brought many inconvenience, the shortcoming of also easily losing, the utility model provides a kind of novel folding dimensioning.
The utility model is achieved in that a kind of novel folding dimensioning, comprise main body set square, adjustable triangle and jockey thereof, described main body set square is isosceles drawing square, the hypotenuse of main body set square is connected with one side of adjustable triangle by the jockey arranging, adjustable triangle can be take the hypotenuse of main body set square and is that axle rotates, and during expansion, adjustable triangle and main body set square are positioned at same plane, when folding, adjustable triangle and main body set square partly overlap.
The inside of described main body set square is provided with protractor, and two right-angle sides of main body set square are provided with rule.
Three interior angles of described adjustable triangle are respectively 135 °, 30 °, 15 °, and the opposite side of 30 ° of interior angles equates with the hypotenuse of main body set square, and are connected with main body set square by jockey, and the opposite side of 135 ° of interior angles is provided with rule.
Described jockey is loose-leaf.
Described jockey is soft rubber band.
During use, can be according to the concrete needs in when mapping, adjustable triangle is rotated, make adjustable triangle and main body set square be positioned at same plane, now can obtain the set square that a hypotenuse is a certain right-angle side twice, when rotating adjustable triangle while arriving lap position with main body set square, just can obtain an isosceles drawing square and a less hypotenuse is the set square of a certain right-angle side twice.
The beneficial effects of the utility model are to make simply, and cost is low, and multiple different Plotting Function is integrated in one, convenient and practical.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of an embodiment of novel folding dimensioning.
In Fig. 1: loose-leaf 1, rule 2, main body set square 3, protractor 4, adjustable triangle 5.
The specific embodiment
Referring to Fig. 1, described main body set square 3 is isosceles drawing square, the hypotenuse of main body set square 3 is connected with one side of adjustable triangle 5 by the loose-leaf 1 arranging, adjustable triangle 5 can be take the hypotenuse of main body set square 3 and is that axle rotates, during expansion, adjustable triangle 5 is positioned at same plane with main body set square 3, and when folding, adjustable triangle 5 partly overlaps with main body set square 3.
The inside of described main body set square 3 is provided with protractor 4, and two right-angle sides of main body set square 3 are provided with rule 2.
Three interior angles of described adjustable triangle 5 are respectively 135 °, 30 °, 15 °, and the opposite side of 30 ° of interior angles equates with the hypotenuse of main body set square 3, and are connected with main body set square 3 by loose-leaf 1, and the opposite side of 135 ° of interior angles is provided with rule 2.
During use, can be according to the concrete needs in when mapping, adjustable triangle 5 is rotated, make adjustable triangle 5 and main body set square 3 be positioned at same plane, now can obtain the set square that a hypotenuse is a certain right-angle side twice, when rotating adjustable triangle 5 with main body set square 3 during to lap position, just can obtain an isosceles drawing square and a less hypotenuse is the set square of a certain right-angle side twice.
Claims (5)
