An invertible line marking instrument and a line marking method of the invertible line marking instrument

Abstract

The invention provides a reversible marking meter. The reversible marking meter comprises a leveling system, a marking component, a microprocessor and an adjusting and driving module. The leveling system is connected with the marking component. The microprocessor is connected with the leveling system, the marking component and the adjusting and driving module. The adjusting and driving module is connected with the marking component. The reversible marking meter is characterized in that, the reversible marking meter also comprises an inversion signal sensor, the inversion signal sensor is connected with the microprocessor, and used for determining whether the marking meter is inverted. The invention also provides a marking method for the reversible marking meter. The novel reversible marking meter is advantageous in that, through the inversion technology, marking work can be performed when the marking meter is placed normally, and marking work can also be performed when the marking meter is placed invertedly, and therefore the distance between the marking glaze of the marking meter and a construction surface is less than or equal to 7 cm, even is less than 5 to 3 cm or lower. The marking precision is raised and construction operations are easy.

Description

technical field [0001] The invention relates to a line marking instrument and a line marking method thereof, in particular to an invertible line marking instrument and a line marking method thereof. Background technique [0002] Laser line markers have been used in engineering and construction for many years. They are commonly used to generate light reference surfaces for architectural projects, for commercial extensions, laying foundations, laying tiles, installing cabinets, installing ceilings, leveling ceilings and installing outdoor decks Wait. When in use, set the laser marking instrument on the ground in front of the construction wall, let it generate laser beams to map on the wall, ground or ceiling, and make the laser beams mapped on the wall, ground or ceiling parallel or perpendicular to the horizontal plane , so that marking and post-construction inspection can be carried out according to the laser beam. Of course, according to needs, the laser marking instrumen...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing laser marking instrument is as follows: figure 1 As shown, the distance h between the light surface 8 formed by the emitted light and the construction surface, ground or instrument support surface is generally relatively large, and it is difficult to achieve less than 10 cm

[0004] In order to achieve the goal that the horizontal smooth surface is closer to the height of the construction surface, the instrument needs to be inverted. After the instrument is inverted, the signal output by the Anping signal sensor after rotating 180° is the same as the original signal, and the motor is driven based on this signal. The effect of adjusting to the level of safety will cause the deviation to become larger and larger
