Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot-fix rhinestones, and in particular to a flat-bottomed hot-fix rhinestone for nail art. Background Technology
[0002] Hot-fix rhinestones were originally decorative items set into materials such as leather and fabric, mainly used to enhance the beauty and decorative effect of products; with the improvement of living standards, hot-fix rhinestones have gradually become a common feature in the nail art industry.
[0003] Existing hot-fix rhinestones are generally made by hot-melting and die-casting materials such as crystal glass or acrylic, and then cutting and polishing the surface to allow them to refract light and achieve a bright, sparkling effect. However, as decorative items fixed to nails for manicures, the cutting and polishing of these rhinestones results in sharp, distinct edges that can easily cause scratches when they come into contact with the skin.
[0004] Therefore, existing hot-fix rhinestones have a relatively poor safety profile. Utility Model Content
[0005] The purpose of this invention is to provide a flat-bottomed hot-fix rhinestone for nail art. This invention has the advantage of good safety.
[0006] The technical solution of this utility model is as follows: a flat-bottomed hot-fix rhinestone for nail art, comprising a hot-fix rhinestone body, the top surface of the hot-fix rhinestone body is spherical, and the bottom surface of the hot-fix rhinestone body has a frustum-shaped groove; the bottom of the hot-fix rhinestone body is connected to a base, and three claws that can cover both ends of the hot-fix rhinestone body are provided on both sides of the top surface of the base.
[0007] In the aforementioned flat-bottomed hot-fix rhinestone for nail art, the top surface of the rhinestone body is provided with a claw groove corresponding to each claw.
[0008] In the aforementioned flat-bottomed hot rhinestone for nail art, the bottom and sides of the groove are provided with a transparent colored coating.
[0009] In the aforementioned flat-bottomed hot rhinestone for nail art, the top surface of the base is provided with a reflective aluminum plating layer.
[0010] In the aforementioned flat-bottomed hot rhinestone for nail art, multiple reinforcing grooves extending towards the center are provided on both sides of the bottom surface of the base, and the reinforcing grooves are trapezoidal in shape, wider at the top and narrower at the bottom.
[0011] In the aforementioned flat-bottomed hot rhinestone for nail art, the bottom surface of the base is connected with hot melt adhesive.
[0012] Compared with existing technologies, this utility model designs the top surface of the hot-fix rhinestone body into a spherical shape, making the top surface of the hot-fix rhinestone body that comes into contact with the outside world smooth and rounded, so that it will not be scratched when the human body rubs against the hot-fix rhinestone body, thus having better safety; by opening a frustum-shaped groove on the bottom surface of the hot-fix rhinestone body and the side surface being composed of multiple planes, light can be continuously refracted when it enters the hot-fix rhinestone body, thus making the hot-fix rhinestone body achieve a bright and sparkling effect, thus having better aesthetics; by connecting the base to the bottom of the hot-fix rhinestone body and setting three claws on both sides of the top surface of the base to cover the two ends of the hot-fix rhinestone body, the hot-fix rhinestone body can be stably connected to the base, thus having better stability.
[0013] In addition, the claw grooves on the top surface of the hot-fix rhinestone body corresponding to each claw ensure that the top surface of the hot-fix rhinestone body remains smooth after the claws have stably locked onto it, preventing the protruding parts of the claws from scratching the human body and providing good safety. Moreover, after the claws are locked into the corresponding claw grooves, the hot-fix rhinestone body can be prevented from shaking, thus improving stability.
[0014] By applying colored coatings to both the bottom and sides of the groove, light passing through the colored coatings can display different colors, resulting in a more aesthetically pleasing appearance.
[0015] By setting a reflective aluminum plating layer on the top surface of the base, the light shining onto the base can be reflected, increasing the light inside the hot-fix rhinestone, enhancing the sparkle effect of the hot-fix rhinestone, and further improving the aesthetics of the hot-fix rhinestone.
[0016] By applying hot melt adhesive to the bottom of the base, the base with the rhinestone attached can be bonded to the nail simply by heating the hot melt adhesive, eliminating the need for additional glue and offering excellent convenience. Multiple reinforcing grooves extending towards the center along the two sides of the base's bottom edge, with a trapezoidal shape that tapers from top to bottom, allow some of the hot melt adhesive to flow into these grooves when heated. After cooling and solidifying, the remaining hot melt adhesive is held in place within the grooves, preventing the base from detaching from the hot melt adhesive and providing good stability.
[0017] Therefore, this utility model not only has good safety, but also has the advantages of good aesthetics, good stability and good convenience. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0026] Example. A flat-bottomed hot-fix rhinestone for nail art, configured as follows: Figures 1 to 6 As shown, it includes a hot-fix rhinestone body 1, the top surface of which is spherical and the bottom surface of which is provided with a frustum-shaped groove 2; the bottom of the hot-fix rhinestone body 1 is connected to a base 3, and the top surface of the base 3 is provided with three claws 4 on both sides that can cover the two ends of the hot-fix rhinestone body 1.
[0027] The top surface of the hot-rhine body 1 is provided with a claw groove 5 corresponding to each claw 4.
[0028] The bottom and sides of the groove 2 are provided with a transparent colored coating 6.
[0029] The top surface of the base 3 is provided with a reflective aluminum-plated layer 7.
[0030] Multiple reinforcing grooves 8 extending towards the center are provided on both sides of the bottom surface of the base 3. The reinforcing grooves 8 are trapezoidal in shape, wider at the top and narrower at the bottom.
[0031] The bottom surface of the base 3 is connected with hot melt adhesive 9.
[0032] Working principle: First, place the hot-fix rhinestone body 1 on the top surface of the base 3, and pry open the multiple claws 4 on both sides of the top of the base 3 so that they are respectively engaged in the claw grooves 5 of the hot-fix rhinestone body 1, thereby fixing the hot-fix rhinestone body 1 to the base 3; then heat the hot melt adhesive 9 on the bottom surface of the base 3 to melt it, and then stick the bottom surface of the base 3 to the nail. At this time, the melted hot melt adhesive 9 is squeezed out, and some of the hot melt adhesive 9 will slowly fill the reinforcing groove 8; after the hot melt adhesive 9 cools and solidifies, it will hold the base 3 in place. When bonded and fixed to the nail, the reinforcing groove 8 is trapezoidal in shape, wider at the top and narrower at the bottom. The hot melt adhesive 9 that cools and solidifies inside the reinforcing groove 8 will be stuck inside the reinforcing groove 8, preventing the base 3 from falling off the hot melt adhesive 9 and enhancing the stability of the base 3. Moreover, the reinforcing groove 8 is distributed on both sides of the bottom of the base 3 and extends towards the middle. Only a small amount of hot melt adhesive 9 is needed to fill the reinforcing groove 8, ensuring that there is a sufficient amount of hot melt adhesive 9 between the bottom of the base 3 and the nail, further improving the stability of the base 3.
[0033] Since the claws 4 on both sides of the top surface of the base 3 can be inserted into the claw grooves 5 on both sides of the top surface of the hot-drill body 1, and the top surface of the hot-drill body 1 is spherical, the top surface of the hot-drill body 1 is round and smooth, without any sharp edges or protrusions, which can effectively prevent the human body from being scratched by rubbing against the sharp edges, and has good safety.
[0034] The frustum-shaped groove 2 on the bottom surface of the hot-fix rhinestone body 1, because its side surface is composed of multiple trapezoidal planes, increases the refraction angle of light entering the hot-fix rhinestone body 1. Moreover, under the reflection effect of the reflective aluminum-plated layer 6 set on the top surface of the base 3, the amount of light entering and exiting the hot-fix rhinestone body 1 is greatly increased, making the hot-fix rhinestone body 1 shiny and having a better aesthetics. The transparent colored coating 5 set on the bottom and side surfaces of the groove 2 allows light to pass through the colored coating 5 and present a colored effect, enhancing the aesthetics.
