Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a measuring tape. Background Art
[0002] The tape measure is a kind of measuring tool. Because of its simple structure, wide measuring range and simple use, it is widely used in many fields such as wood, metal and construction measurement. The common tape measure has a size scale on its scale bar, and the measured size is read by observing the scale line where the scale bar is aligned with the edge of the object. There are several problems with the existing tape measure. First, due to the high work intensity and different personal vision conditions of the measuring personnel, the operator may not be able to ensure that the vision is within a reasonable range due to the limitations of working conditions. It is easy to see the scale line of the scale bar or the scale line where the outline of the object is aligned with the scale line. Another reason is that many edges of the measured objects are not right-angled edges but have small chamfers or rounded edges. Some edges of the measured objects are inner holes or outer holes, and the edge contours of some objects are not clear. As a result, the scale of the scale bar surface and the edge of the object do not fit together, and there will be a certain distance where the value cannot be read correctly, resulting in the problem of difficulty in reading the value and inaccurate values.

[0042] Working process
[0043] 1. When measuring the position of a hole on an object, first hook the hook of the tape measure on one side of the object, then place the first contact surface 203 on the secondary hook 2 on the tape measure against the position on the inner wall of the measured hole closest to the hook of the tape measure, and then observe the first indicating surface 404 of the scale pointer 4 and the position where the scale on the tape overlaps through the magnifying glass 604 to read the corresponding reading. Then place the second contact surface 205 on the secondary hook 2 against the position on the inner wall of the hole farthest from the hook of the tape measure, and this time observe the second indicating surface 405 on the scale pointer 4 and the position where the scale on the tape overlaps through the magnifying glass 604 to read the corresponding reading.
[0044] 2. When the edge of the object to be measured is not a right-angled edge but a plate with a small chamfer or rounded corner, use the edge of the tape measure hook at one end to pass over the small chamfer and hook the plane, and use the first contact surface 203 on the auxiliary hook 2 at the other end to pass over the small chamfer and hook the plane, then use the magnifying glass 604 to observe the overlap position of the front end surface of the scale pointer 4 and the scale on the ruler to read the corresponding reading.
[0045] 3. Such as Figure 8 As shown, when the value obtained by the cooperation between the ruler hook and the first contact surface 203 on the auxiliary ruler hook 2 is used to measure the object, the value of scale 1 in the figure should be read accordingly. When the value obtained by the cooperation between the ruler hook and the second contact surface 205 on the auxiliary ruler hook 2 is used to measure the object, the value of scale 2 in the figure should be read accordingly.
