Easy-to-carry building inspection scale

Abstract

The invention discloses a convenient and portable scale for building inspection, which comprises a first measuring ruler, a second measuring ruler and a tape measure body. A second rotating shaft is arranged at an inner middle position of the tape measuring body, and a second rotating shaft is arranged on the second rotating shaft. A rotating handle is connected to the outer side of the tape measure body, and a pulling belt is wound around the two rotating shafts. A rotating connection card is provided at the middle position of the back shell of the tape measure body, and a first telescopic rod is sleeved on the rotating connecting card. and the second telescopic rod, and pointer heads are welded at the ports of the first telescopic rod and the second telescopic rod. In the present invention, the first measuring ruler and the second measuring ruler are connected through the rotating shaft, and the second measuring ruler is connected with the tape measure body. When measuring the construction device, especially for the first measuring ruler and the second measuring ruler at the corner It is convenient to measure, you can use a tape measure to measure, making the measurement more convenient.

Description

technical field [0001] The invention relates to the technical field of building surveying equipment, in particular to a convenient and portable scale for building testing. Background technique [0002] A ruler is not a ruler, but a tool used to draw line segments (especially straight ones) and measure length. There are usually scales on the ruler to measure the length. Some rulers have special shapes such as letters or circular holes in the middle, which is convenient for users to draw pictures. First of all, the use of the ruler must be correct. Plastic rulers can get scratched easily. There are also many people who make a mistake, that is, when drawing lines, they are very fast, and then they will slide along the ruler because of the slippery characteristics of the ruler, which will mess up the value, so the speed is moderate. A ruler is a graduated rod used to measure the vertical distance between a point on the ground and the horizontal line of sight of a surveyor. ...

AI Technical Summary

Problems solved by technology

[0003] However, there are some deficiencies in the existing building inspection scales during use. The volume of the scale is too large to be carried easily, and it is inconvenient to use the scale to measure at some corners, and it is difficult to adjust the level of the scale, so that the scale There are great limitations in the use process
