Description

Ceiling laser level device

The present invention relates to a laser level device for a ceiling, and more particularly, to automatically measure the ceiling height, irradiate a center line on the ceiling, and a lens according to the horizontal line separation distance value and the vertical line separation distance value input by the operator. It relates to a laser level device for the ceiling that is automatically adjusted to the angle and irradiated to the ceiling at regular intervals.

When constructing a building, it is one of the important conditions for the performance and durability of these structures to be constructed horizontally and vertically.

Therefore, in various fields such as architecture, civil engineering, and interior interior, accurate setting of horizontal and vertical positions on the space is one of the important tasks.

This vertical and horizontal setting method is a method of measuring by artificially hanging a string on the ceiling, and the work is difficult and dangerous, and it is difficult to expect an accurate setting due to the phenomenon of the string shaking, and the inconvenience of measuring from top to bottom. Of course, there were problems such as lack of speed and accuracy due to frequent work and moving places.

In addition, during the indoor lighting installation work, there is a difficulty in measuring and marking the lighting installation location with a tape measure before installing the lighting on the ceiling. In particular, there was a problem in that it takes a long time to work because the worker has to become a group of 2 people to form a grid pattern on the ceiling, manually measure the intervals of lighting, and repeat the climb and descend using a ladder. .

In order to solve such problems, Korean Patent Publication No. 10-1682518 "Laser level irradiation apparatus capable of displaying a grid" has been posted. When constructing a building, a laser is irradiated to the ceiling in a grid form to install various lighting devices, etc., and it is difficult to control the grid pattern spacing because the grid pattern spacing of the laser line is irradiated with a preset value. There was a problem that the lens to be adjusted must be manually adjusted. Therefore, the lens is manipulated by the operator by hand, resulting in poor precision and poor workability and efficiency.

The present invention has been devised to solve the above problems, by automatically measuring the height of the ceiling from the body frame placed on the floor, and calculating the rotation angle values of the horizontal line forming body and the vertical line forming body according to the input separation distance value. The purpose is to calculate and allow the horizontal line forming body and the vertical line forming body to automatically rotate according to the rotation angle value.

In addition, the center line can be marked long and clearly by the center line laser, and there is another purpose to automatically irradiate the ceiling with a horizontal line and a vertical line spaced apart from the center line by a certain interval.

In order to achieve the above object, the present invention includes a body frame placed on the bottom surface; A distance measuring device disposed at the top of the center of the main frame and automatically measuring the height of the ceiling by irradiating the wave body onto the ceiling and detecting the wave body before reflection; A center line laser disposed to be spaced apart in an x-axis direction and a y-axis direction based on the position of the distance measuring device, and irradiating a cross-shaped center line on the ceiling; A horizontal line forming body consisting of one or more horizontal line lasers disposed to be spaced left and right in the x-axis direction of the center line laser and rotating at a set angle to irradiate a horizontal line on the ceiling; A vertical line forming body comprising one or more vertical line lasers disposed vertically apart in the y-axis direction of the center line laser and rotating at a set angle to irradiate a vertical line on the ceiling; An input panel disposed at a set position and configured to set a horizontal line separation distance value and a vertical line separation distance value; And a controller configured to control the horizontal line forming body and the vertical line forming body to rotate by receiving the horizontal line and the vertical line separation distance value and calculating a rotation angle value.

In addition, the center line laser is characterized in that it is disposed in all directions based on the location of the distance measuring device.

In addition, the horizontal line forming body is formed in a plurality of pairs symmetrically left and right in the x-axis direction of the center line laser, and rotation angle values of each pair are individually calculated according to a horizontal line separation distance value.

In addition, the vertical line forming body is formed in a plurality of pairs to be symmetrical vertically in the y-axis direction of the center line laser, and rotation angle values of each pair are individually calculated according to a vertical line separation distance value.

In addition, the horizontal line forming body and the vertical line forming body may include a light source body for irradiating light; A light diffusing lens surrounding the light source body and having a horizontal line forming groove or a vertical line forming groove thereon; And a lens rotation actuator that is connected to the light diffusion type lens and receives a rotation angle value from the controller to rotate the light diffusion type lens.

The laser level device for a ceiling according to the present invention by means of solving the above problems can automatically measure the height of the ceiling without a worker climbing on a ladder, and it can be used by a single operator with a simple operation, so that workability and convenience are excellent.

In addition, the center line is clearly marked vertically from the center of the device to the ceiling by the center line laser, and it can be used in a wide space, thereby improving usability.

In addition, there is an advantage in that the horizontal line forming body and the vertical line forming body are automatically rotated based on the center line according to the separation distance value input by the operator, and the working time is reduced by constantly irradiating the ceiling.
