Description
Technical Field
The utility model relates to the technical field of straightedges, in particular to a straightedge capable of accurately drawing angles.
Background
The ruler is also called a ruler and is mainly used for measuring length and drawing lines, scales are usually arranged on the upper surface of the ruler for indicating the length, most of the ruler is made of plastic, iron, stainless steel and other materials, and the ruler can be a straight ruler, a triangular ruler and the like in the stationery range according to the shape of the straight ruler.
The conventional straight ruler is mostly in a regular straight plate structure, and an angle with an accurate angle cannot be drawn.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a ruler capable of accurately drawing an angle of a specified angle.
The utility model is realized by the following technical scheme:
ruler of accurate drawing angle, including main scale and vice chi, the main scale is the cuboid structure, be provided with the scale mark on the main scale, vice chi is "U" type open-ended cuboid structure, vice chi cladding is in the main scale is peripheral, its characterized in that: the upper surface of the one end of the auxiliary ruler is provided with a protractor, the protractor is provided with a rivet, the rivet is arranged at the original point position of the protractor, the rivet is used for riveting and connecting the main ruler with the auxiliary ruler and the protractor together, the main ruler is used for riveting and connecting the main ruler with the auxiliary ruler and the protractor respectively and independently surrounding the rivet to rotate, the main ruler is used for riveting and connecting the auxiliary ruler with the protractor, the main ruler is further provided with a positioning groove respectively on the auxiliary ruler, the positioning groove is used for penetrating through the rectangular groove structure of the main ruler and the auxiliary ruler, and the positioning groove is collinear with the rivet.
Further, the main ruler and the auxiliary ruler are made of rubber.
Beneficial effects of the utility model
The ruler of accurate drawing angle, the upper surface of the one end of vice chi is provided with the protractor, be provided with the rivet on the protractor, the rivet sets up the initial point position of protractor, the rivet will the main scale with vice chi reaches protractor three riveting together, the main scale with vice chi reaches the protractor can center on alone respectively the rivet is rotatory, the main scale with still be provided with the constant head tank on the vice chi respectively, the constant head tank is for running through the main scale with the rectangular groove structure of vice chi, the constant head tank with the rivet collineation can aim at the scale of protractor respectively with the constant head tank on main scale and the vice chi, takes the pencil to draw the straight line along two constant head tanks and can accurately draw the angle of appointed angle.
Preferably, the main scale and the auxiliary scale are made of rubber, the rubber has certain elasticity, and the main scale and the auxiliary scale are difficult to lose due to collision or falling.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
in the figure, 1, a main ruler, 2, an auxiliary ruler, 3, scale marks, 4, a positioning groove, 5, a rivet and 6, a protractor are arranged.
Detailed Description
As shown in fig. 1, the ruler for accurately drawing angles provided by the utility model comprises a main ruler 1 made of rubber and having a cuboid structure and an auxiliary ruler 2 made of rubber, wherein the main ruler 1 is provided with scale marks 3, the auxiliary ruler 2 is in a U-shaped open cuboid structure, the auxiliary ruler 2 is wrapped on the periphery of the main ruler 1, the upper surface of one end of the auxiliary ruler 2 is provided with a protractor 6, the protractor 6 is provided with a rivet 5, the rivet 5 is arranged at the original point position of the protractor 6, the main ruler 1, the auxiliary ruler 2 and the protractor 6 can respectively and independently rotate around the rivet 5, rectangular positioning grooves 4 are respectively cut through the main ruler 1 and the auxiliary ruler 2, and the positioning grooves 4 and the rivet 5 are collinear to ensure the accuracy of angle drawing by means of the protractor 6.
The working mode is as follows: when the ruler is used for drawing an angle of a specified angle, the zero-degree line of the protractor 6 is aligned to the central line of the positioning groove 4 on the auxiliary ruler 2, then the main ruler 1 is screwed out of the auxiliary ruler 2, when the central line of the positioning groove 4 on the main ruler 1 is adjusted to be aligned to the degree of the specified protractor 6, the pencil is used for drawing straight lines along the central lines of the positioning grooves on the main ruler 1 and the auxiliary ruler 2 respectively, and the two straight lines are crossed, namely, drawing of the angle of the specified angle is completed, and the main ruler 1 and the auxiliary ruler 2 are both made of rubber materials, so that the ruler has certain advantages in the anti-collision function.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
