Abstract
A portable multipurpose measuring instrument integrates mechanical design and electronic technology, is capable of rapidly and visually measuring arc lengths, distances and angles, and is mainly used for daily teaching and engineering measurement. The portable multipurpose measuring instrument comprises an outer casing, handles, a laser probe, a spring, gears, a rotary shaft, a fixing rod and a rotary plate, wherein the spring is fixed between the two handles. The portable multipurpose measuring instrument achieves the purpose of measuring arc lengths, distances and angles by the aid of transitivity between the gears and internal laser ranging equipment.
Description
Affiliated technical field
The utility model relates to a kind of portable multi-purpose measuring instrument that integrates Machine Design and electronic technology.
Background technology
At present, known telemeasurement, radius measurement, arc length are measured several measuring equipments of basic need and are used just and can finish, and relatively trouble can't satisfy the actual needs that shortens construction period, improves efficiency of measurement.
The utility model content
The purpose of this utility model provides a kind of portable multi-purpose measuring instrument that integrates Machine Design and electronic technology.The portable multi-purpose measuring instrument mainly is to be made of handle, laser probe, gear, rotating shaft, fixed bar five parts.Wherein, rolling disc connects inner rotating shaft, can drive rotating shaft each gear rotation on every side; Handle top has laser probe, can change with handle to take measurement of an angle; The handle bottom is connected and fixed bar, and fixed bar drive handle can change the angle between the handle; Spring is fixed between two handles, and two handles automatically can bounce back.The portable multi-purpose measuring instrument mainly drives rotating shaft by rolling disc, thereby each gear is rotated, and then change takes measurement of an angle with driving two fixed bar uniform velocity.By the Laser Distance Measuring Equipment feedback data, and angle shown in the index dial, by formula l=θ * R and
By the internal microprocessor data processing, demonstrate arc length, distance, the angle of required measurement, thereby reached the purpose of convenient and swift measurement.
Beneficial effect
The utility model has the advantages that:
1, convenient and swift;
