Triangle leveling instrument

Abstract

The invention discloses a triangle leveling instrument which comprises a rotating shaft (1), a circular level gauge (2) arranged on the top of the rotating shaft (1), and level rulers (3), and is characterized in that one end of each level ruler (3) is connected with a bearing (4); the bearings (4) are arranged on the rotating shaft (1) in a sheathing manner; each level ruler (3) is provided with a long hole (5); a bracket rod (6) capable of sliding in each long hole (5) is arranged in the long hole (5); the three level rulers (3) are sequentially arranged on the rotating shaft (1) in the sheathing manner by the bearings (4) from top to bottom; the bottoms of the three bracket rods (6) are arranged in the same horizontal plane and are lower than the lowest plane of the rotating shaft (1). The triangle leveling instrument is high in measurement accuracy; the three bracket rods can rotate around the rotating shaft, so that the measured plane can be measured along any direction; the bracket rods can slide on the level rulers, so that the positions of the bracket rods on the level rulers can be adjusted according to the individual demand, and the measurement range is large.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a triangular level. Background technique [0002] In the process of manufacturing, assembling equipment, product inspection, etc., a level is usually needed to check the level of the plane. Currently, the commonly used levels include frame-type levels and long-square-type levels. When measuring, the level is directly placed on the measured plane. Since the bottom of the level is a plane and the measured plane is surface-to-surface contact, the measurement accuracy is not high, and the level can only measure whether the measured plane is horizontal in one direction at a time. If you want to measure whether the measured plane is horizontal in another direction, you need to change the direction of the level meter and measure it separately, which is troublesome to measure. [0003] In order to solve the above-mentioned technical problems, the patent application number 2011200376...

Problems solved by technology

When measuring, the level is directly placed on the measured plane. Since the bottom of the level is a plane and the measured plane is surface-to-surface contact, the measurement accuracy is not high, and the level can only measure whether the measured plane is horizontal in one direction at a time. If you want to measure whether the measured plane is horizontal in another direction, you need to change the direction of the level meter and measure it separately, which is troublesome to measure

[0003] In order to solve the above-mentioned technical problems, the patent application number 201120037603.0 discloses a multi-directional spirit level, which is mainly composed of two long flat-ruled spirit levels hinged together and can only measure two directions of the side plane at the same time, and now The length of the level meter in the technology is all fixed, so when the level meter measures a plane with a diameter smaller than the diameter of the level meter, the measurement is inaccurate because a part of the level meter cannot touch the measured plane; When the diameter of the level is large, it is troublesome to measure many times because the level is too small and the measurement results are not accurate. Therefore, a level with a certain length can only measure a plane within a certain diameter range, and the plane is too large or too large. Small can not be measured, the measurement range is relatively small
