Distance-adjustable laser level

Abstract

The invention discloses a distance-adjustable laser level which is characterized by comprising a shell body, a driving device, a control system, a power supply and a distance measurement module, wherein the driving device comprises a motor and transmission devices; the control system comprises a microprocessor, a direction sensor, a laser module and a driving circuit; the motor is connected with the microprocessor through the driving circuit, the direction sensor is connected with the microprocessor, the distance measurement module is connected with the microprocessor, the laser module is connected with the microprocessor, the laser module is arranged on the Y-axis transmission device, and the driving device can make the laser module to rotate around the X axis, the Y axis and the Z axis.The distance-adjustable laser level disclosed by the invention has a simple structure; the distance-adjustable laser level not only can generate laser lines at any angle, but also can generate specific-distance parallel lines; the distance-adjustable laser level can be remotely controlled to adjust laser lines at any angle and generate specific-distance laser lines at any angle; a reference line can be made without a ruler, and construction time is shortened.

Description

technical field [0001] The invention relates to the field of optical instrument manufacturing, in particular to a laser marking instrument with adjustable spacing. Background technique [0002] Laser line markers or spirit levels are commonly used in the construction industry. A traditional laser marking instrument includes: a frame, a pendulum, wherein the pendulum is suspended on the frame through a universal mechanism and uses gravity to define a vertical plumb line, and at least includes a laser beam emitter, which is installed on the pendulum On, used to emit a laser plane, which is projected on the object to form a straight laser line, which is used as a plumb or horizontal line to facilitate operations in construction or decoration. [0003] The current laser marking instrument projects a straight laser line by hanging heavy objects and using gravity. The heavier the weight, the higher the accuracy. Due to the heavy weight of the instrument, the accidental drop of t...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of the instrument, the accidental drop of the instrument often occurs during the customer's transportation, movement or daily use. The universal mechanism is very easy to cause damage to the bearing, bending of the shaft system and other adverse phenomena due to the large impact force, resulting in a decrease in the sensitivity of the universal structure. , the movement cannot be reset accurately, which affects the light index, so the traditional laser marking instrument has a high failure rate. In addition, the traditional laser marking instrument can only be used for marking lines, and cannot meet the requirements of some building construction. If you need a horizontal line at a certain position, but you can only measure it with a ruler
