Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measurement, in particular to a portable measuring ruler for construction engineering. Background Art
[0002] The tape measure is a common measuring tool in daily life. The one you often see is the steel tape measure, which is commonly used in construction and decoration, and is also one of the essential tools for the family. The tape measure can be rolled up because there is a spring inside the tape measure. When it is pulled out to measure the length, it actually lengthens the ruler and the spring. Once the measurement is completed, the spring inside the tape measure will automatically shrink, and the ruler will also shrink under the action of the spring force, so the tape measure will roll up.
[0003] Traditional measuring tapes are thin, and when they are wound up, the winding spring winds up the tape at a fast speed, which can easily cut people's hands. Traditional measuring tapes generally do not have a level measurement function, so workers need to carry a level measuring instrument, which brings inconvenience to their work. Utility Model Content
