Description

Technical Field

[0001] The utility model relates to the field of nail polish grinding heads, in particular to a hard alloy nail polish precision grinding head. Background Art

[0002] The nail grinding head is a component of nail care tools and is often installed on electric nail grinders for trimming, polishing, grinding and carving the nail surface and surrounding skin. It processes natural nails, false nails or cuticles through high-speed rotation, helping manicurists to perform detailed trimming work.

[0003] In the prior art, the grinding portion of a traditional nail grinding head is usually a single shape structure. When processing nails of different shapes and positions, it is often difficult to take into account both at the same time. Users need to frequently switch between grinding heads of different shapes to adapt to different nail grinding needs. This not only increases the complexity of operation, but also easily causes fatigue to users after long-term operation. In addition, traditional nail grinding heads often adopt an integrated structure. When the grinding head is worn or damaged, the nail grinder needs to be disassembled to replace the entire grinding head, which not only increases the cost of use, but also the replacement process is more complicated, affecting work efficiency.

[0004] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a hard alloy nail polish precision grinding head which is easy to use and improves the grinding efficiency.

[0024] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figures 1 to 3 As shown, the embodiment of the utility model provides a carbide nail polish precision grinding head, comprising a grinding head 1, a positioning rod 2, a locking ring 3 and a grinding head handle 4;

[0028] The sharpening head 1 includes a first grinding part 11 and a second grinding part 12. The first grinding part 11 has a hemispherical structure, and the second grinding part 12 has a conical structure. The first grinding part 11 is connected to the positioning rod 2 through the second grinding part 12. The surface of the first grinding part 11 is provided with a plurality of mutually adjacent triangular prism structures 110; the combination of the first grinding part 11 with a hemispherical structure and the second grinding part 12 with a conical structure can enable the grinding head to have two grinding functions. The first grinding part 11 is suitable for grinding a wide range of nail surfaces, and the second grinding part 12 is suitable for grinding deep into narrow or special-angle areas, such as nail edges, nail crevices, etc.; the sharp edges of the multiple triangular prisms can increase the cutting performance of the sharpening head 1, thereby efficiently removing nail material and improving grinding efficiency.

[0029] The bottom of the grinding head 1 is connected to the positioning rod 2, and the positioning rod 2 is provided with a symmetrically arranged positioning block 20. The middle part of the grinding head handle 4 is provided with a sleeve hole 40 for inserting the positioning rod 2, and the side wall of the grinding head handle 4 is provided with a positioning groove 401 connected to the sleeve hole 40. The positioning groove 401 is used to connect the positioning block 20 to limit the rotation of the positioning rod 2 relative to the grinding head handle 4. The outer wall of the grinding head handle 4 is provided with an external thread structure 402, and the locking ring 3 is provided with an internal thread structure (not shown). The locking ring 3 is connected to the grinding head handle 4 by a thread to limit the positioning block 20 from slipping out of the positioning groove 401. The symmetrical positioning blocks 20 on the positioning rod 2 are embedded in the positioning grooves 401 on the side walls of the grinding head handle 4 to form a mechanical lock, which limits the rotation of the positioning rod 2 relative to the grinding head handle 4, prevents grinding deviation caused by high-speed rotation of the grinding head, and improves grinding accuracy; when the locking ring 3 is tightened, the positioning blocks 20 are pressed to prevent them from sliding out of the positioning grooves 401, and prevents the grinding head 1 from loosening or falling off under high-speed rotation, thereby improving operational safety; and, by loosening the locking ring 3, the grinding head 1 can be easily removed from the grinding head handle 4. This arrangement allows users to quickly replace the grinding head 1 without disassembling the entire nail grinder or using disassembly tools, effectively improving work efficiency.

[0030] like Figure 1 and Figure 2 As shown, further, the second grinding portion 12 is provided with a plurality of arcuate structures 120 along the circumferential direction. Compared with the sharp edges of the triangular prism structure 110, the arcuate structure 120 has a smoother transition surface, thereby reducing excessive grinding of the nail during the grinding process and making the grinding surface fine.

[0031] Furthermore, the first grinding portion 11 and the second grinding portion 12 are connected by laser welding. Such an arrangement can improve the overall structural strength of the grinding head 1.

[0032] Furthermore, the diameter of the positioning rod 2 is 2-8 mm. In this embodiment, the diameter of the positioning rod 2 is 4 mm.

[0033] like Figure 2 and Figure 3 As shown, further, a transition slope structure 403 is provided on the top of the grinding head handle 4. Such a configuration can facilitate the locking ring 3 to be inserted into the grinding head handle 4 for locking connection.

[0034] like Figure 1 and Figure 2 As shown, further, the surface of the locking ring 3 is provided with an anti-slip texture structure 30, which can increase the friction between the locking ring 3 and the human hand to prevent slipping during tightening or loosening the locking ring 3.

[0035] Furthermore, the surfaces of the first grinding portion 11 and the second grinding portion 12 are coated with a TiN coating. The TiN coating has extremely high hardness and can effectively improve the wear resistance of the grinding head.

[0036] Furthermore, the grinding head 1 is made of tungsten steel hard alloy. Tungsten steel hard alloy has high hardness, is not easy to wear or become blunt, can maintain good grinding efficiency under long-term use conditions, and has a long service life.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
