A level using a buoy

Abstract

The invention relates to a level instrument using a buoyancy, which comprises a housing, a supporting shaft, a measuring member, an angle distinguishing member, and a buoyancy body. The internal space of the housing is filled with liquid and a first display window and second display window are formed in the side and upper part of the housing. The supporting shaft is horizontally fixed inside the housing. The measuring member is shaft-joined in the supporting shaft to be rotated and moved to left and right sides. The angle distinguishing member is formed in one side of the first and second display windows and measuring member, thereby distinguishing horizontal, vertical, and inclined angles. The buoyancy body is joined to a side of the measuring member. According to the invention, a sleeve groove formed in the middle of the two sides of the disc-shaped measuring member is supported by a hemispherical supporting part at the other end of the supporting shaft; the measuring member can rotate and move to left and right; therefore, only one display window formed on the top or at the bottom is used for measuring horizontal, vertical, and inclined angles; and with a stop pin which can fix the measuring member, measured data can be distinguished accurately and conveniently.

Description

technical field [0001] The present invention relates to a level instrument which can measure the vertical, horizontal and inclination degree of the installation surface during the operation of construction engineering or mechanical equipment. A level using a floating body to which a measuring device can be fixed so that the scale to which the measuring device is identified can be identified. Background technique [0002] Generally speaking, a level is a measuring tool used to confirm the level or vertical degree during the construction of building structures or the installation of mechanical equipment. It is long and portable. [0003] This traditional level is in the shape of a long strip, which is convenient to stick to the horizontal or vertical surface. There is a transparent measuring tube in the center. Liquid and a small amount of air are injected into the transparent measuring tube to generate bubbles. According to the movement of the bubbles generated in the measuri...

Problems solved by technology

[0004] However, in the above-mentioned traditional level, the scale is divided at an appropriate distance in the middle of the measuring tube, and the bubbles generated in the liquid move between them according to the level, and the level or vertical level is recognized with the naked eye, but the position of the bubbles seen can be determined. Due to the difference in the angle and position seen by the naked eye, it is often necessary to reconfirm the measurement data repeatedly, and because the moving position of the bubble is limited to a certain range, the measurement level stays at the level of confirming the approximate inclination, which cannot be accurate Measure tilt angle
