Title:
DIAMETER TAPE
Document Type and Number:
WIPO Patent Application WO/2023/151457
Kind Code:
A1
Abstract:
A diameter tape, comprising a body (10). Perimeter scales (11) extending in the length direction are provided on the body (10), and comprise an origin (A) and perimeter scale lines sequentially distributed. The origin (A) and the perimeter scale lines are respectively located on two sides of the width of the body (10). The origin (A) is used for indicating the perimeter scale line when measuring the perimeter of an object to be measured. The distance F(L) between each perimeter scale line and a perpendicular foot (B) which is formed by the perimeter scale line and a straight line passing the origin (A) is distributed one by one according to [Equation 1], wherein L is the numerical value marked by the scale line of each perimeter scale (11), x is the thickness neutral layer parameter of the body (10); when the diameter tape is used for measuring the outer diameter, x is a positive number; when the diameter tape is used for measuring the inner diameter, x is a negative number; t is the thickness of the body (10), and d is the width of the body (10).
