Abstract

PURPOSE: A horizontal and vertical measurement tool having a lamp and a laser point is provided to measure a horizontal state of a far-distant region at a time by attaching the laser point to a level such that a laser beam passes through the level in parallel to the level. CONSTITUTION: A horizontal and vertical measurement tool includes a level(1). A plurality of notch mark checking lamps(8-a,8-b,8-c) are attached to the level(1) so as to allow a user to easily check a position of bubbles through a plurality of notch mark windows(7-a,7-b,7-c). A laser point(4) is attached to the level(4) in parallel to the level(4) so as to measure a horizontal state or a vertical state of a far-distant region at a time. The notch mark is easily checked even if the level(4) is in a dark place due to light radiated from the laser point(4).

Description

Horizontal and vertical measuring tool with scale verification lamp and laser point}

The present invention mainly relates to the level used to measure the level at the construction site in general, by filling a liquid of about 90% in a transparent glass tube and measuring by determining whether the bubble position of the remaining portion is located within the display scale. come.

This method is very easy to measure relatively accurate horizontal level, so it is mainly used in construction sites, but it is difficult to identify the location of bubbles because it is mostly dark inside the building under construction, so it is necessary to install a separate work lamp or use something like a flashlight. There is an uncomfortable problem.

In addition, since the length of the horizontal system is not long, it is difficult to measure the horizontality of a long section at a time.

The present invention has been invented to solve the problem that it is difficult to identify the bubble position in a dark workplace or a narrow space and it is difficult to measure the horizontal level more than the length of the horizontal level to easily identify the bubble position in the dark by attaching a small lamp to the existing horizontal scale window In addition to providing a means to enable this, a laser point is attached to the level to transmit the laser light in parallel with the level so that the laser can be measured at a distance to a far distance where the laser light reaches.

This will be described in detail below.

In general, in the construction site to use the horizontal level as shown in Figure 1, and fill the liquid 10 in the glass tube of the horizontal check graduation window (7-b) installed in parallel with the horizontal body (1) A method of judging horizontality is used to determine whether the position of the remaining bubbles 11 is within the display scales (12-a, 12-b). Horizontal, oblique and vertical measurements were made at (7-c). However, the measurement beyond the length of the main body 1 was impossible.

Figure 2 is a perspective view of the present invention as a way to solve the above problems, the overall configuration, and the existing horizontal body 1 and the 45 degree tilt oblique check grid (7-a) and the horizontal check grid (7) -b) Install small lamps (8-a, 8-b, 8-c) in the vertical check scale window (7-c) and turn off the check lamp switch (2-b) when checking the scale in the dark. When turned on, the small lamps (8-a, 8-b, 8-c) will light up, allowing the scale to be checked even in the dark, and leveling the laser point (4) that emits laser light in parallel with the horizontal body (1). When attached to the main body (1) and turned on the laser point power switch (2-a) was able to measure the horizontal and vertical to the far place where the laser light reaches.

Here, the laser point may be installed on both sides or one side of the horizontal body 1, and the light emitted from the laser point 4 may appear on the surface 9 as a point, a vertical line, or a horizontal line as shown in FIG. You can apply any shape that doesn't deviate.

Here, the power source of the small lamps 8-a, 8-b, 8-c and the laser point 4 uses the battery 5, and any battery without departing from the gist may be applied.

Figure 6 is a circuit diagram applied to the present invention is a circuit for checking the diagonal check grid (7-a), the check lamp (8-b), the vertical check grid (7-c) graduation check lamp (8-c) The power supply can be turned on and off at the same time by the check lamp switch (2-b), and the laser point (4) for measuring the horizontal level to a distance is composed of a separate circuit. For example or convenience of using the point power switch (2-a) may be configured as a single circuit, any circuit without departing from the gist can be applied.

In addition, a tripod fixing nut groove 3 for attaching a tripod may be attached to the horizontal body to maintain a vertical line and a horizontal line of the laser point 4.

Level meter having a check lamp and laser point according to the present invention can be applied without greatly modifying the existing horizontal shape, there is no inconvenience in use, no need for a separate lighting device in a dark and narrow environment, the length of the level It is possible to measure more horizontally and vertically over longer distances at the same time, thereby reducing the measurement error range and making it easy to check even in a dark environment.
