JP2001074451A - Box-shaped horizontality and verticality measuring device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a box-shaped horizontality and verticality measuring device, in which one bubble tube is mounted on a transparent rectangular parallelepiped box, so that the box has two horizontality and verticality measuring roles, in which a mirror is attached so that the movement of an air bubble can be observed visually easily and whose operating efficiency is improved. SOLUTION: When the horizontality of an object 7 to be measured is measured, a bubble tube 1 is attached to the object 7 to be measured by a bottom magnet 4. When the verticality of an object 6 to be measured is measured, the bubble tube 1 is attached to the object 6 to be measured by a rear magnet 3. A measuring operator can capture the front-and-rear motion of an air bubble 11 as a vertical motion on the image of a mirror 2 so as to be visible very easily, and a measuring operation becomes easy. Since horizontality and verticality measurement can be performed by one bubble tube, the cost becomes low. In addition, the front-and-rear motion of the air bubble is changed into the vertical motion on a mirror surface, the measurement becomes easy, and the operating efficiency of this box-shaped horizontality and verticality measuring device is enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal / vertical measuring device.

[0002]

2. Description of the Related Art Conventionally, using a plurality of bubble tubes,
There was an instrument to measure vertical.

[0003]

A conventional horizontal / vertical measuring instrument has a plurality of bubble tubes for horizontal and vertical measurements, which is costly and difficult to see.

[0004]

Means for Solving the Problems One bubble tube (1) is mounted on the lower surface of a transparent rectangular box (FIG. 1) so that the box itself can perform two functions of horizontal and vertical measurement. Attach a mirror on top of it with a 45 degree tilt angle.

[0005]

Embodiments of the present invention will be described below. (A) When measuring the level of the measurement object (7), the measurement object (7) is attached to the measurement object (7) by the low-side magnet (4). (B) When measuring the perpendicularity of the measuring object (6), the measuring object (6) is attached to (6) by the magnet (3) on the back surface. (C) Since the measurer can perceive the back and forth movement of the bubble (11) as a vertical movement in the image of the mirror (2),
It is very easy to see and measurement work is easy.

[0006]

According to the present invention, horizontal and vertical measurements can be made with a single bubble tube, the cost is reduced, and the back and forth movement of the bubbles is changed to up and down movement on a mirror surface, making it easy to perform large measurements. The work efficiency is remarkably improved.
