Description

A Laser Angle Measuring Instrument

technical field

The invention belongs to the field of measuring instruments, in particular to a laser opening angle measuring instrument.

Background technique

In engineering work or mechanical drawing, it is often necessary to measure various angles. The most commonly used measuring tool is a protractor, but the protractor is a contact measurement. When it is necessary to measure the angles such as the opening angle of a distant object to the observer, it is difficult to use a general protractor.

Contents of the invention

The technical problem to be solved by the present invention is to provide a laser opening angle measuring instrument capable of conveniently and accurately measuring various angles, especially various opening angles.

In order to solve the above technical problems, the present invention adopts the following technical solutions: a laser opening angle measuring instrument, which is composed of a main body, a first leg, a second leg, a first laser and a second laser, the main body is provided with a rotating shaft, a display screen, power button, angle-radian conversion button, the upper ends of the first leg and the second leg are respectively fixed on the rotating shaft, and the lower ends of the first leg and the second leg are fixedly connected to the the first laser and the second laser.

The laser emission directions of the first laser and the second laser are respectively consistent with the length directions of the first leg and the second leg.

The main body is provided with a rotation angle sensor and a digital conversion module, and the rotation angle sensor is connected with the rotating shaft for measuring the clamp between the first leg and the second leg; the digital conversion module is respectively connected to the The rotation angle sensor is electrically connected to the display screen, and is used to convert the angle measured by the rotation angle sensor into a digital signal and display it on the display screen.

Due to the adoption of the above design, the present invention has a simple structure, is practical and convenient, and can realize non-contact measurement of various angles.
