Description

Angle ruler

Technical Field

The invention relates to the technical field of measuring tools, in particular to an angle ruler.

Background

The angle ruler is a common tool for measuring angles, and the currently used angle ruler cannot directly measure angles below 20 degrees.

Disclosure of Invention

In view of the technical shortcomings, the invention aims to provide an angle ruler which can measure any angle and solve the problem that the existing angle ruler cannot measure angles below 20 degrees.

In order to solve the technical problems, the invention adopts the following technical scheme:

the utility model provides a bevel protractor, includes bevel protractor and scale, the bevel protractor includes a bevel protractor, No. two bevel protractors are fixed to be set up the right side of a bevel protractor and with a bevel protractor is integrated into one piece structure, the scale includes a scale, No. two scales, a scale with a bevel protractor is articulated mutually and articulated the department is located the radial center of a bevel protractor, the rear end of a scale is equipped with a needle axle, a needle axle with a scale is integrated into one piece structure, No. two scales with No. two bevel protractors are articulated mutually and articulated the department is located the radial center of No. two bevel protractors, the top of No. two scales is fixed and is equipped with No. two needle axles, No. two needle axles with No. two scales are integrated into one piece structure.

The invention has the beneficial effects that: this design is equipped with a scale, No. two scales rather than articulated respectively on an angle square, No. two angle scales for a scale, No. two scales can carry out the rotation measurement of arbitrary angle on an angle square, No. two angle scales, and can use different measurands to the measurement angle of difference, make this device can both carry out accurate measurement to arbitrary angle.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, an angle ruler, including angle ruler and scale, the angle ruler includes angle ruler 1 No. 2, No. 2 fixed settings are on angle ruler 1's right side and with an angle ruler 1 as an organic whole shaping structure, the scale includes scale 3 No. 3, No. 4, scale 3's rear portion and an angle ruler 1 articulate mutually and articulated department is located the radial center of an angle ruler 1, make scale 3's front end can carry out the rotation of arbitrary angle round a radial center of an angle ruler 1, in order to be used for measuring arbitrary angle, scale 3's rear end is equipped with a needle axle No. one, a needle axle and a scale are the organic whole shaping structure, make scale 1 can drive a needle axle when measuring the angle and rotate the corresponding degree numerical value on a directional angle ruler 1, No. 4's center department and No. 2 articulated and articulated department is located No. 2 radial center of an angle ruler 2 Make No. two scales 4 can carry out the rotation of arbitrary angle around No. two angular ruler 2's center department to can both measure arbitrary angle, No. two scales 4's top center department is fixed to be equipped with No. two needle axles, and No. two needle axles and No. two scales 4 be integrated into one piece structure, and when No. two scales 4 measured rotatoryly, No. two needle axles can point to corresponding degree numerical value on No. two angular ruler 2.

When the angle gauge is used, when the measured angle is greater than or equal to 90 degrees, the bottom edge of the first angle gauge 1 is aligned to one side of the angle to be measured, the first scale 3 is rotated to enable the scale edge of the first scale to be aligned to the other side of the angle to be measured, the degree value on the first angle gauge 1 pointed by the next needle shaft is recorded at the moment, and the degree value obtained by subtracting the degree value pointed by the first needle shaft from 180 degrees is the degree value of the measured angle; when the measured angle is smaller than 90 degrees, the first scale 3 is rotated, the scale edge of the first scale 3 is aligned with one edge of the angle to be measured, the second scale 4 is rotated, the bottom edge of the second scale is aligned with the other edge of the angle to be measured, and the sum of the degree value indicated by the first needle shaft and the degree value indicated by the second needle shaft is the degree value of the angle to be measured.

According to the invention, the first angle scale and the second angle scale are respectively provided with the first scale and the second scale which are hinged with the first angle scale and the second angle scale, so that the first scale and the second scale can be used for rotating and measuring at any angle on the first angle scale and the second angle scale, and different measuring sides can be used for different measuring angles, so that the device can be used for accurately measuring any angle.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
