Embodiment

[0011] Example: such as figure 1 As shown, a ruler suitable for quickly measuring hand size is designed and manufactured, which includes a ruler body 100 made of hard transparent plastic. The ruler body 100 is provided with 22 round through holes 200 with different diameters along the length direction. The sizes are arranged in order from small to large and from left to right.

[0012] Below the round through hole 200 is provided a paint layer 300 marked with different models of hand sizes, so that the diameter and circumference of the corresponding hand size can be compared according to the size of the hand size.

[0013] In Mainland China, Hong Kong, and even well-known ring manufacturers, there are cases where the same hand size model indicates different hand size. Embodiments of the present invention refer to the "Standard Ring Size Comparison Table" commonly used in mainland China. The diameter and circumference of the hand-inch models represented by the hand-inch models...

Abstract

The invention discloses a ruler suitable for quickly measuring the finger size. The ruler comprises a ruler body made of hard transparent plastic. The ruler body is provided with a plurality of round through holes with different diameters in the length direction, and the round through holes are arranged in the sequence from small to big and from left to right according to the diameters. A pigment layer marked with different types of finger sizes is arranged below the round through holes, so that the diameters and perimeters of corresponding finger sizes are obtained according to the types of the finger sizes in a comparison mode. The ruler is used for measuring the diameters and perimeters of the finger sizes and is accurate in measurement and especially easy and fast to operate.

Description

technical field [0001] The invention relates to the technical field of rings, in particular to a ruler suitable for quickly measuring hand size. Background technique [0002] For a long time, people have liked to wear rings on their fingers as decorations. Since the size of the hand varies from person to person, different fingers of the same person, the same finger at different ages, and even in different seasons, the size of the hand will not be the same. Before buying or customizing a ring, you must first measure the diameter and circumference of your hand. The devices currently on the market for measuring the diameter and circumference of hands have the defects of inaccurate measurement and cumbersome operation. Contents of the invention [0003] The object of the present invention is to provide a ruler for measuring the diameter and circumference of a hand, which is not only accurate in measurement, but also particularly simple and fast in operation. [0004] The te...
