Description

measuring tape structure and measuring method using same

Technical Field

The invention relates to a measuring tape, in particular to a measuring tape structure and a measuring method with the same.

Background

Tape measures are common measuring tools in daily life, and are widely used due to small size and portability.

At present, as chinese utility model patent with patent number CN201720363209.3 (No. CN206756013U), this tape measure with hook extension mechanism includes the casing, the chi mouth that takes out that supplies the scale to wear out is opened on the global of casing, the edge of taking out chi mouth be equipped with hook matched with butt piece, butt piece can supply the whole bearing of hook on it, and still have the telescopic machanism that can make the hook deviate from the removal of taking out chi mouth direction on the butt piece, telescopic machanism includes magnetic sheet and the telescopic link of being connected with the magnetic sheet, the telescopic link is worn to locate in the butt piece, the magnetic sheet is located hook and deviates from casing one side, and attract mutually with the hook. The measuring tape can realize measurement, but the measuring tape is single in measurement, when the distance between two objects is required to be measured, the scale value is read from the measuring tape, the size of the shell of the measuring tape is required to be measured, the distance between the two objects can be obtained, the measuring process is complicated, the size value needs to be calculated manually, errors are easy to occur, and the measuring inconvenience is increased.

For another example, in the field of steel tape measurement, there is no tape that can actually measure the internal distance between two objects to be measured (which generally refers to the distance between two objects to be measured in the space) accurately and conveniently. At present, when the distance between two objects to be measured is measured, the bending is needed to be performed at the tail end of the final tape, and the measuring result is very inaccurate by visually observing the scale value.

Accordingly, there is a need for further improvements to existing tape measure constructions.

2) And reading a scale value corresponding to the first scale, wherein the scale value is the scale value corresponding to the first end wall of the shell adjacent to the free end of the scale belt.

Compared with the prior art, the first scale on the tape measure structure is convenient to measure the distance between two objects to be measured, avoids the complexity caused by measuring the distance between the two objects to be measured by adopting a common tape measure, and is more convenient to use; the second ruler has the same function as the common tape, so that the same tape can be used as the common tape and can also be used for measuring the distance between two objects, the application range is wider, and the structure is more reasonable; the measuring method for measuring the distance between the two objects to be measured by adopting the measuring tape structure is simple, convenient, time-saving and accurate.
