Description

Technical Field

[0001] The utility model relates to the technical field of hairpins, in particular to a metal clip-type hairpin. Background Art

[0002] Hairpins are an indispensable daily item in women's daily life. They can be used to temporarily clamp hair and decorate hair. Since hairpins are small tools used to fix and decorate hair, they are widely used in daily life and various occasions.

[0003] Authorization announcement number CN201967998U discloses a hairpin comprising a decorative body and a snap arm. The decorative body has a pivoting member and a positioning member protruding from each end of the body. The pivoting member has a pivot hole. One end of the snap arm is pivoted into the pivot hole of the pivoting member, and the other end is a resilient snap ring corresponding to the positioning member. The outer diameter of the positioning member is larger than the inner diameter of the corresponding position of the snap ring. The snap arm is a steel wire connected end to end in the shape of an "8". One end of the steel wire is a pivoting ring pivotally connected to the pivoting member, and the other end is the snap ring.

[0004] However, there is still room for improvement in the aforementioned hairpin. For example, although the snap arm is connected to the pivot hole of the pivot member via the pivot ring, this structure that solely utilizes the pivot hole to position the pivot ring may still swing left and right after long-term use due to deformation of components. In other words, the stability between the pivot ring and the pivot member is not good enough. When the pivot ring swings, it becomes difficult to accurately mate with the positioning member, and the two are prone to misalignment, resulting in poor performance. Utility Model Content

[0005] In view of the problems existing in the above-mentioned prior art, the purpose of the present utility model is to provide a metal clip-on hairpin, which limits the retaining spring through structural improvement, so that the retaining spring is not prone to swinging, and the retaining spring can accurately cooperate with the pin, is not prone to misalignment, and is easy to use.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A metal clip-on hairpin, comprising a decorative body, a holder, a retaining spring and a pin, all of which are made of metal; the holder is provided with two vertical limiting grooves opening toward the pin and penetrating vertically, and the two vertical limiting grooves are symmetrically arranged; a horizontal limiting groove penetrating both sides of the holder and communicating with the two vertical limiting grooves is also provided on the bottom surface of the holder; one end of the retaining spring is a retaining ring corresponding to the pin and having deformable elasticity, the outer diameter of the pin is larger than the inner diameter of the corresponding position of the retaining ring, and the other end of the retaining spring is two symmetrically arranged clamping strips; each of the clamping strips is away from the pin. Each end of the snap ring has an L-shaped, downwardly bent snap-in portion. The upper end of each snap-in portion fits within a vertical limiting slot, and the lower end fits within a horizontal limiting slot, allowing the snap spring to flip up and down. The widths of the vertical limiting slot and the horizontal limiting slot correspond to the outer diameter of the snap-in portion. A first and a second mounting blind hole are provided on the top surfaces of both ends of the ornament, respectively. The lower end of the holder fits within the first mounting blind hole, the horizontal limiting slot is also located within the first mounting blind hole, and the lower end of the pin fits within the second mounting blind hole. The vertical and horizontal limiting slots can be used to correspondingly limit the snap spring, preventing it from swinging.

[0008] Furthermore, an anti-slip sticker is included; the anti-slip sticker is installed in the middle of the top surface of the ornament, so that the hairpin can clamp the hair more stably.

[0009] Furthermore, the middle part of the clip is in a downwardly concave arc shape, so that after the buckle ring is engaged with the pin, the middle part of the clip can fit with the top surface of the anti-slip sticker, so that the clip and the anti-slip sticker can clamp the hair better and more stably.

[0010] Furthermore, a positioning groove for cooperating with the snap ring is provided on the four sides of the pin, so that the snap ring can be more stably fastened to the pin; the upper end of the pin is spherical, so that the snap ring can be smoothly inserted into the buckle.

[0011] Furthermore, the buckle ring is in the shape of an oval thin strip.

[0012] Furthermore, the connection between the buckle ring and the two clamping strips is in an "X" shape.

[0013] Furthermore, the card holder and the first mounting blind hole are connected by bonding, welding, or inlaying; and the pin and the second mounting blind hole are connected by bonding, welding, or inlaying. This arrangement ensures that the connection between the card holder and the first mounting blind hole, and the connection between the pin and the second mounting blind hole, is very stable and unlikely to become loose.

[0014] Furthermore, the ornament body, the holder, the retaining spring and the clasp are all made of titanium alloy.

[0015] Furthermore, the cross section of the ornament is rectangular, elliptical or teardrop-shaped.

[0016] Furthermore, when the cross section of the ornament is rectangular, the four sides of the ornament are wavy.

[0017] The beneficial effects of the utility model are:

[0018] The utility model provides a vertical limiting groove and a horizontal limiting groove on the clamping base, so that the vertical limiting groove and the horizontal limiting groove can be used to limit the clamping spring accordingly, so that the clamping spring is not likely to swing left and right even after the hairpin has been used for a long time, and the buckle ring can be accurately buckled on the buckle pin during the flipping process, and is not likely to be misplaced, which is more convenient to use.

[0019] Specifically, since the widths of the vertical limit groove and the horizontal limit groove correspond to the outer diameters of the clamping part respectively, the specific setting method can be that the widths of the vertical limit groove and the horizontal limit groove are slightly larger than the outer diameter of the clamping part. In this way, the two limit grooves can be used to prevent the clamping part from swinging, that is, the retaining spring can be prevented from swinging.

[0020] In addition, since the ornament body, holder, spring and pin of the present invention are all made of lightweight titanium alloy metal, they can achieve decorative effects with colorful patterns through processes such as anodizing or engraving, making them more beautiful and able to meet the needs of different people. At the same time, the metal structure also makes the hairpin more durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0034] like Figure 1-Figure 7 As shown, a metal clip-on hairpin includes a decorative body 1, a base 2, a clamping spring 3 and a pin 4, all of which are made of metal; two vertical limiting grooves 21 are provided on the base 2, which are open to the pin 4 and pass through the upper and lower parts, and the two vertical limiting grooves 21 are symmetrically arranged; a horizontal limiting groove 22 is also provided on the bottom surface of the base 2, which passes through both sides of the base 2 and is respectively connected to the two vertical limiting grooves 21; one end of the clamping spring 3 is a clamping ring 31 corresponding to the pin 4 and having deformable elasticity, the outer diameter of the pin 4 is larger than the inner diameter of the corresponding position of the clamping ring 31, and the other end of the clamping spring 3 is two symmetrically arranged clamping strips 32; each clamping strip 32 is away from the clamping strip 31. The ends of the buckles 31 are all L-shaped and bent downwardly. The upper end of each clamping part 321 is matched to be inserted into a vertical limiting groove 21, and the lower end is matched to be inserted into the horizontal limiting groove 22, so that the retaining spring 3 can be flipped up and down; the widths of the vertical limiting groove 21 and the horizontal limiting groove 22 correspond to the outer diameters of the clamping part 321 respectively; a first mounting blind hole 11 and a second mounting blind hole 12 are respectively provided on the top surfaces of both ends of the ornament 1, the lower end of the holder 2 is embedded in the first mounting blind hole 11 and the horizontal limiting groove 22 is also located in the first mounting blind hole 11, and the lower end of the pin 4 is embedded in the second mounting blind hole 12.

[0035] like Figure 1-Figure 7 As shown, the metal clip-on hairpin also includes an anti-slip sticker 5, which is installed in the middle of the top surface of the ornament body 1. After the anti-slip sticker 5 is provided, it can cooperate with the clip spring 3 to allow the hairpin to clamp the hair more stably.

[0036] like Figure 1-Figure 7 As shown, in this embodiment, in order to ensure the use effect, the anti-slip sticker 5 is strip-shaped and the extending direction of the anti-slip sticker 5 is the same as the extending direction of the decorative body 1.

[0037] like Figure 1-Figure 3 and Figure 7 As shown, in addition, a positioning groove 41 for cooperating with the snap ring 31 is provided on the four sides of the pin 4, so that the snap ring 31 can be more stable when it is fastened to the pin 4.

[0038] like Figure 1-Figure 3 and Figure 7 As shown, in this embodiment, the upper end of the pin 4 is spherical, so that the snap ring 31 can be smoothly inserted into the pin 4.

[0039] like Figure 1-Figure 7 As shown, in this embodiment, the snap ring 31 is in the shape of an oval thin strip.

[0040] like Figure 1-Figure 7 As shown, in this embodiment, the connection between the snap ring 31 and the two snap strips 32 is in an "X" shape, so that the snap ring 31 and the snap strips 32 at both ends can be easily distinguished.

[0041] In this embodiment, the holder 2 and the first mounting blind hole 11 are connected by bonding, welding, or inlaying; the pin 4 and the second mounting blind hole 12 are also connected by bonding, welding, or inlaying. Therefore, the above arrangement provides a very stable connection between the holder 2 and the first mounting blind hole 11, and between the pin 4 and the second mounting blind hole 12, and prevents them from loosening.

[0042] In this embodiment, the body 1, the holder 2, the spring 3, and the pin 4 are all made of titanium alloy. However, those skilled in the art will appreciate that the body 1, the holder 2, the spring 3, and the pin 4 may be made of other metals that achieve the same effect, and these will not be described in detail here.

[0043] like Figure 1-Figure 3 As shown, in this embodiment (ie, the first embodiment), the cross section of the ornament body 1 is rectangular.

[0044] like Figure 7 As shown, in the second embodiment, the cross section of the decorative body 1 is rectangular and the four sides of the decorative body 1 are wavy.

[0045] like Figure 8 As shown, in the third embodiment, the cross section of the ornament body 1 is elliptical.

[0046] like Figure 9 As shown, in the fourth embodiment, the cross section of the decorative body 1 is in the shape of a teardrop.

[0047] Therefore, the decorative body 1 has multiple design styles to facilitate people to freely choose the design they want. However, those skilled in the art should know that the style of the decorative body 1 can also be set to other shapes according to actual needs, which are not given as examples here.

[0048] In the above four embodiments, the middle portion of the clamping spring 3 is in the shape of a straight strip. Figure 10 As shown, in the fifth embodiment, the middle portion of the clip spring 3 is concavely curved, so that after the snap ring 31 is engaged with the pin 4, the middle portion of the clip spring 3 can be in contact with the top surface of the anti-slip sticker 5. Specifically, the two connecting strips 32 are used to be in contact with the top surface of the anti-slip sticker 5, thereby enabling the clip spring 3 and the anti-slip sticker 5 to better and more stably clamp the hair.

[0049] The specific operating principle of the utility model is introduced below to facilitate understanding of the utility model:

[0050] First, with the spring clip 3 open, insert the spring clip 3 into the hair; then, press the spring clip 3 to flip it over until the snap ring 31 contacts the pin 4, and the pin 4 opens the snap ring 31; then, the upper end of the pin 4 is inserted into the snap ring 31; when the snap ring 31 falls to the position of the positioning groove 41, it returns to its original shape, so that the snap ring 31 is clamped in the position of the positioning groove 41, that is, the spring clip 3 is fixed, and the hair is also clamped by the hairpin.

[0051] In summary, the present invention provides the vertical limiting groove 21 and the horizontal limiting groove 22 on the clamping base 2, thereby enabling the vertical limiting groove 21 and the horizontal limiting groove 22 to correspondingly limit the position of the clamping spring 3, so that even after a long period of use, the clamping spring 3 is unlikely to swing left and right, thereby allowing the snap ring 31 to accurately engage with the pin 4 during the flipping process and not easily misaligned. Specifically, because the widths of the vertical limiting groove 21 and the horizontal limiting groove 22 correspond to the outer diameter of the clamping portion 321, the specific arrangement can be such that the widths of the vertical limiting groove 21 and the horizontal limiting groove 22 are slightly larger than the outer diameter of the clamping portion 321. In this way, the two limiting grooves can be used to prevent the clamping portion from swinging, that is, to prevent the clamping spring 3 from swinging. Furthermore, since the body 1, holder 2, spring 3, and pin 4 of the present invention are all made of lightweight titanium alloy, they can be decorated with colorful patterns through processes such as anodizing or engraving, making them more beautiful and catering to the needs of different people. Furthermore, the metal structure also makes the hairpin more durable. Therefore, the overall structure of the present invention is easy to use, durable, and not easily damaged.

[0052] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
