[0015] Furthermore, the annular anti-slip layer on the first magnetic attraction part and the annular anti-slip layer on the second magnetic attraction part are positioned opposite each other.

[0016] Furthermore, the annular anti-slip layer is an anti-slip rubber layer.

[0017] In the above technical solution, the magnetic PU hair extensions provided by this utility model have the following beneficial effects:

[0018] This magnetic PU hair clip uses a magnetic connection between the first and second magnetic parts to clamp and secure the wearer's hair. The recessed and raised docking structures precisely align, further enhancing the grip and ensuring a stable fit that won't easily fall off.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-2 Magnetic PU hair extensions, including PU hair extension 1. This PU hair extension 1 can be a conventionally used PU hair extension on the market, but for improvement, it also includes:

[0026] The first magnetic part 2 and the second magnetic part 3 are fixedly connected to the PU material base of the PU hairpiece 1, which combines this technology with the traditional PU hairpiece. The first magnetic part 2 and the second magnetic part 3 are connected by magnetic attraction and the user's own hair is clamped between the first magnetic part 2 and the second magnetic part 3, so as to connect the PU hairpiece 1 to the wearer's hair and fix it on the wearer's head.

[0027] An embedded docking structure is provided between the first magnetic suction part 2 and the second magnetic suction part 3. The embedded docking structure is used to press the user's own hair. Compared with the clamping connection between the first magnetic suction part 2 and the second magnetic suction part 3, it further enhances the stability of the clamping connection. At the same time, it makes the edges of the first magnetic suction part 2 and the second magnetic suction part 3 aligned when docking, so as to achieve the effect of accurate docking when the first magnetic suction part 2 and the second magnetic suction part 3 are magnetically connected, making wearing more convenient, quick and accurate.

[0028] Furthermore, the first magnetic part 2 is fixedly connected to the PU material substrate of the PU sheet 1 by an adhesive. The connection is not limited to adhesive; it can also be achieved by heat fusion or other connection methods, which are conventional methods and will not be described in detail here.

[0029] Furthermore, both the first magnetic suction part 2 and the second magnetic suction part 3 are magnetic strips, which can be soft magnetic strips to match the head shape. In another embodiment, the first magnetic suction part 2 and the second magnetic suction part 3 can also be prepared by mixing magnetic powder and polyurethane adhesive in a specific ratio to form an adhesive strip. The length of the adhesive strip depends on the product specifications. Subsequently, the cured adhesive strip is placed in professional equipment for magnetization treatment to impart magnetism. The magnetization method is also common knowledge and will not be described in detail.

[0030] Furthermore, the embedded docking structure includes a docking groove 4 disposed on the first magnetic suction part 2 facing the side opposite to the PU sheet 1, and a docking protrusion 5 disposed on the second magnetic suction part 3 for embedding into the docking groove 4.

[0031] Furthermore, the connecting protrusion 5 is a truncated cone structure, and the connecting groove 4 is a truncated cone groove structure corresponding to the connecting protrusion 5. During the process of the first magnetic part 2 and the second magnetic part 3 clamping the wearer's hair, a portion of the hair will be pressed into the connecting groove 4 by the connecting protrusion 5 and clamped in place. The connecting structure differs from the planar connection between the first magnetic part 2 and the second magnetic part 3. Its protruding structure, when clamping the hair, also causes the hair to deform with the shape of the connecting protrusion 5 and bend, improving the stability of the clamped hair connection and making it less likely to fall off. At the same time, the connecting protrusion 5 embedded in the connecting groove 4 also plays a positioning role, ensuring that the first magnetic part 2 and the second magnetic part 3 are neatly aligned, making the operation convenient and quick during the wearing process.

[0032] Furthermore, annular anti-slip layers 6 are provided on the outer side of the mating groove 4 on the first magnetic suction part 2 and on the outer side of the mating protrusion 5 on the second magnetic suction part 3.

[0033] Furthermore, the annular anti-slip layer 6 on the first magnetic attraction part 2 and the annular anti-slip layer 6 on the second magnetic attraction part 3 are positioned opposite each other.

[0034] Furthermore, the annular anti-slip layer 6 is an anti-slip rubber layer. The rubber layer has an anti-slip effect, and anti-slip patterns can also be set on the surface to further enhance the anti-slip effect.

[0035] Specifically, after the first magnetic part 2 and the second magnetic part 3 are connected, the annular anti-slip layer 6 on the first magnetic part 2 and the second magnetic part 3 also overlap and connect with each other, and simultaneously press the hair, further enhancing the clamping stability of the hair, making it less prone to slipping, and effectively preventing the magnetic PU hairpiece from falling off the head.

[0036] In summary, this magnetic PU hair clip uses the magnetic attraction between the first and second magnetic parts to clamp and secure the wearer's hair. The recessed and raised docking structures of the embedded docking structure precisely align and enhance the clamping force, ensuring a stable fit and preventing it from falling off. It features a convenient wearing and removal process, saving time and allowing for repeated use. The magnetic design avoids the potential damage to the scalp caused by traditional clips and double-sided tape, improving user comfort.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
