[0030] refer to Figures 1 to 6 A nail grinder according to an embodiment of the present invention is described.
[0031] like Figures 1 to 6 As shown, the nail grinder according to the embodiment of the utility model includes a fixed seat 100; a grinding groove 200, which is arranged in an arc shape on the fixed seat 100, and a plurality of grinding protrusions 210 are arranged on the groove wall of the grinding groove 200, and the plurality of grinding protrusions 210 are evenly distributed along the groove wall of the grinding groove 200.
[0032] like Figure 1 and Figure 2 As shown, the fixing seat 100 is a cube extending in the left-right direction, and the grinding groove 200 is an arc groove arranged on the top of the fixing seat 100, and the opening of the grinding groove 200 is arranged upward. Specifically, the groove wall of the grinding groove 200 is covered with grinding protrusions 210, and the grinding protrusions 210 are evenly arranged along the extension direction of the groove wall of the grinding groove 200. Therefore, by placing the nail in the grinding groove 200 and moving the finger left and right, the nail can be polished into a smooth arc through the grinding protrusions 210 on the groove wall of the grinding groove 200. On the other hand, the grinding protrusions 210 are all arranged on the grinding groove 200 that is concave inward, thereby reducing direct contact with other objects, reducing surface friction and collision, reducing the risk of the grinding protrusion 210 being scratched, worn or damaged, and extending its service life.
[0033] It should be noted that the shape of the grinding groove 200 can be a standard arc shape or other curved shapes.
[0034] In some specific implementations of the present invention, the grinding groove 200 includes a first wall surface 220 and a second wall surface 230, the first wall surface 220 and the second wall surface 230 are symmetrically arranged, and a plurality of grinding protrusions 210 are arranged on the first wall surface 220 and the second wall surface 230. Figure 3 As shown, the first wall surface 220 and the second wall surface 230 are symmetrical about a symmetry axis arranged in the up-down direction, and the polishing protrusions 210 are evenly distributed along the extension direction of the first wall surface 220 and the second wall surface 230. Specifically, the polishing protrusions 210 are arranged in a chain, and the multiple polishing protrusions 210 on the first wall surface 220 are symmetrically arranged with the multiple polishing protrusions 210 on the second wall surface 230.
[0035] In some specific implementations of the present invention, the cross section of the grinding groove 200 is V-shaped. It should be noted that the grinding groove 200 with a V-shaped cross section can provide users with clearer guidance and guide the correct position and angle of the nail during the grinding process. Specifically, the user can place the nail in the grinding groove 200 so that the nail forms a more stable contact with the grinding protrusion 210. The nail can be better supported in the groove, reducing the shaking or sliding of the nail during the grinding process, thereby making it easier to control the strength and direction of the grinding, and improving the accuracy and stability of the operation. At the same time, the grinding groove 200 with a V-shaped cross section can be adjusted according to the size and shape of the nail to adapt to different nail sizes, ensuring that the grinder can fit the nail tightly and provide a more effective grinding effect.
[0036] In addition, the grinding grooves 200 are symmetrically arranged, and their cross-sectional shapes include but are not limited to V-shape, U-shape, etc.
[0037] In some specific implementations of the present invention, the grinding protrusion 210 is inclined in a direction away from the bottom of the grinding groove 200. Figures 3 to 5 As shown, the polishing protrusion 210 is an oblique rhombus. Specifically, the first wall surface 220 is tilted downward from left to right, and the axial direction of the polishing protrusion 210 on the first wall surface 220 extends in the up-down direction, that is, compared with the plane where the first wall surface 220 is located, the polishing protrusion 210 on the first wall surface 220 is tilted to the left. Symmetrically, the second wall surface 230 is tilted downward from right to left, and the axial direction of the polishing protrusion 210 on the second wall surface 230 extends in the up-down direction, that is, compared with the plane where the second wall surface 230 is located, the polishing protrusion 210 on the second wall surface 230 is tilted to the right. Therefore, the polishing protrusions 210 on the first wall surface 220 and the second wall surface 230 are both arranged to adapt to the direction of change in nail thickness to achieve a better polishing effect.
[0038] In some specific implementations of the present invention, avoidance portions 240 are provided at both ends of the grinding groove 200 along the arc extension direction, and the cross-sectional area of the avoidance portions 240 gradually decreases along the groove bottom direction away from the grinding groove 200. The avoidance portions 240 are used to prevent sharp edges from scratching fingers.
[0039] like Figure 1 and Figure 3 As shown, the front and rear ends of the grinding groove 200 are both provided with avoidance portions 240, and the avoidance portions 240 are arranged along the arc extension direction of the grinding groove 200, that is, the avoidance portions 240 are arranged in parallel at the front and rear ends of the edge of the grinding groove 200. In this specific embodiment, the avoidance portion 240 is an inclined surface connecting the grinding groove 200 and the fixing seat 100, that is, the notch of the grinding groove 200 is connected to the avoidance portion 240 through a chamfered inclined surface, and the chamfering can reduce the sharpness of the notch edge of the grinding groove 200. When the nail moves in the grinding groove 200, the chamfering can alleviate the direct contact between the nail and the notch edge, prevent the nail edge from being scratched or damaged, and thus reduce the risk of nail injury.
[0040] In some specific implementations of the present invention, the fixing base 100 is made of metal.
[0041] It should be noted that metal is a strong and durable material with high hardness and wear resistance. Therefore, metal materials can withstand long-term use, are not easy to wear, deform or break, and can provide a long-lasting service life. At the same time, during the polishing process, metal materials can absorb and dissipate heat faster, avoid nails from overheating due to friction, improve polishing efficiency, and reduce discomfort during the polishing process. Metal materials are easy to clean and disinfect, and can effectively prevent the growth of bacteria, viruses and other contaminants. Compared with other materials, metal is easier to clean and can be kept hygienic and safe by washing, disinfection or disinfectant treatment.
[0042] In some specific implementations of the utility model, the fixing seat 100 is a cube extending in the left-right direction, and the grinding groove 200 is an arc groove set on the top of the fixing seat 100 and concave downward. The cross section of the grinding groove 200 is V-shaped, and the opening is set upward. Among them, there are a plurality of grinding protrusions 210 in a chain array on the first wall surface 220 and the second wall surface 230. The grinding protrusions 210 are oblique prisms extending in the up-down direction. The oblique prisms on the left and right sides are symmetrically arranged. When the bracket is placed in the grinding groove 200, the oblique prisms on the front and back sides will grind between them, and the nails can be polished smooth by swinging the fingers left and right.
[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
