A cat's eye shaped metal bead

Abstract

The utility model provides a metal bead product with a cat's eye appearance. The metal bead is spherical or ellipsoidal, with a straight line passing through the center of the sphere or the major axis or minor axis of the ellipsoid as the central axis, and linear grooves are carved in the meridian direction of the metal bead surface. The cross section of the groove is V-shaped and is composed of two groove walls. The utility model reasonably sets the angle between the two groove walls, and the two groove walls are perpendicular to each other, so that the light irradiated on the groove wall is reflected in a direction parallel to the incident light, so that the surface of the spherical bead forms a glass-like translucent effect, which has both the unique luster of gold material and a layer of glass-like translucent luster, forming a bead product similar to a cat's eye.

Description

Technical Field

[0001] The invention relates to a metal ornament, in particular to a cat's eye type metal bead. Background Art

[0002] Ordinary gold bead jewelry with smooth or mirror effects is highly recognizable when viewed from near or far. They are all spherical beads with gold as the base material. They are very popular in the market, and their structures and processes are very mature. However, the surfaces of gold bead jewelry on the market are mostly smooth or frosted, and their structures appear to be relatively simple in appearance. The purpose of the present utility model is to improve this technical problem. Summary of the invention

[0003] Based on this, the utility model aims to overcome the defects of the prior art and provide a metal bead with a cat's eye appearance.

[0004] The utility model discloses a metal bead with a cat's eye appearance, wherein the metal bead is spherical or ellipsoidal, and comprises an outer surface of the metal bead.

[0005] When the metal bead is spherical, the central axis of the metal bead (a geometrical straight line) passes through the center of the metal bead; when the metal bead is ellipsoidal, the central axis of the metal bead passes through the major axis or minor axis of the metal bead.

[0006] Evenly distributed linear grooves are carved on the surface of the metal bead. The linear grooves start from a geometric intersection of the central axis and the outer surface of the metal bead and end at another geometric intersection of the central axis and the outer surface of the metal bead. The linear grooves are distributed throughout the surface of the entire metal bead, that is, the outer surface of the metal bead is provided with a plurality of micro linear grooves extending along its meridians and arranged closely and continuously, and the distance between each linear groove is approximately the same.

[0007] The linear groove is V-shaped in cross section and is composed of two groove walls that are angled to each other, that is, the linear groove includes a first groove wall and a second groove wall that intersect, and the angle between the first groove wall and the second groove wall ranges from 85° to 95°. Preferably, the angle between the first groove wall and the second groove wall is 90° or approximately 90°.

[0008] The linear grooves are evenly and closely arranged on the surface of the metal bead. From the cross section perpendicular to the central axis, a single groove is V-shaped. In the cross section, the linear grooves are arranged in a stepped manner. The purpose of this arrangement is to make the cat's eye effect on the outer surface of the metal bead more significant.

[0009] Preferably, the width of the linear groove is between 0.1 mm and 0.5 mm.

[0010] Preferably, the depth of the linear groove is between 0.03 mm and 0.3 mm.

[0011] Preferably, the metal bead further comprises a through hole. Preferably, a central axis of the metal bead can be determined according to the meridians of the outer surface of the metal bead, and the through hole passes through the central axis.

[0012] The advantages of this application compared to the prior art are:

[0013] The utility model processes and carves linear grooves on the surface of the metal bead, and the cross section of the groove is V-shaped, that is, it is composed of a first groove wall and a second groove wall with an angle of nearly 90 degrees. Since the first groove wall and the second groove wall are perpendicular to each other, when light is incident in a direction perpendicular to the bottom line of the groove, no matter from which direction the light irradiates the surface of the metal bead, it will be reflected back in a direction parallel to the incident light. Because the linear grooves are evenly distributed on the outer surface of the entire metal bead, the gold spherical bead ornaments can visually present a transparent, cat-eye-like effect, forming a new category of gold jewelry products.

[0020] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] As an embodiment, the present application provides a metal bead having a cat-eye appearance, such as Figure 1As shown, the metal beads are spherical or ellipsoidal in shape as a whole. In this embodiment, the metal beads are spherical and include:

[0022] The outer surface 1 of the metal bead, the central axis 2 passing through the center of the metal bead, and the through hole 2 along the direction of the central axis n.

[0023] The outer surface 1 of the metal bead is covered with linear grooves 11 along the spherical meridian direction of the metal bead. The linear grooves 11 all start from an endpoint where the central axis 2 intersects with the spherical surface of the metal bead outer surface 1 (this endpoint is only a geometric intersection point and does not necessarily actually exist on the outer surface of the metal bead), and end at the other endpoint where the central axis 2 intersects with the spherical surface of the metal bead outer surface 1.

[0024] like Figure 2 , Figure 3 As shown, the groove 11 includes a first groove wall 12 and a second groove wall 13, both of which are planes, and the angle γ between the two groove walls is 85°-95°, preferably, the angle γ between the two groove walls is 90°. The width of the first groove wall 12 is a, and the width of the second groove wall 13 is b, and the ranges of a and b are both 0.03mm-0.3mm, and the distance between two adjacent grooves is between 0.1mm-0.5mm.

[0025] like Figure 4 As shown, L is the direction of the light source, and the arrow shows the propagation direction of the light after it hits the outer surface 1 of the metal bead. Because the first groove wall 12 is perpendicular to the second groove wall 13, when the light is incident in a direction perpendicular to the bottom line of the groove, the light irradiated to any point of the linear groove 11 will be reflected back in a direction parallel to the incident light, and because the lines of the linear groove 11 are evenly distributed, when the light is projected onto the outer surface 1 of the metal bead, a glass-like translucent effect is formed on the surface of the spherical bead, which has both the unique luster of the gold material and a layer of glass-like translucent luster, forming a visual effect similar to a cat's eye.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
