Description

Technical Field

[0001] This application relates to the field of accessory technology, and particularly to hairpins.

Background Art

[0002] As a commonly seen hair accessory, hairpins are widely used in daily life. They not only have a practical function of fixing hair, but also have a decorative effect, which can improve the overall image of an individual.

[0003] In related technologies, ordinary hairpins adopt a normal clamping structure and fix hair with a simple spring or clip. However, both the spring and the clip are simple mechanisms and there is a need to enhance their decorative effects.

Summary of the Invention

Problems to be Solved by the Invention

[0004] This application provides a hairpin in order to overcome the above technical problems.

Means for Solving the Problems

[0005] The hairpin includes a clamping member and a decoration fixedly connected to the clamping member.

[0006] By adopting the above technical solution, the decoration is fixedly attached to the clamping member, and the clamping member is used to clamp hair to ensure the stability of the decoration.

[0007] Optionally, the decoration includes a stacked composite member and a sticker member, and the composite member is fixedly connected to the clamping member.

[0008] By adopting the above technical proposal, a systematic integration of decorative function, visual effect, and practical function is achieved. The sticker component provides a concrete character decoration surface, and the composite component provides an abstract background of light and shadow. By physically superimposing the two, a composite visual effect rich in tonal gradation is created. By directly fixing the clamping component to the composite component, which is the core component that carries the visual effect, the connection strength and unity between the decorative body and the fixing device are ensured, solving the problems of conventional hairpin decorative elements, which are monotonous, easily fall off, or lack visual gradation.

[0009] Selectively, the composite member (1) is either an opaque plastic member or a transparent plastic member with a printed layer (102).

[0010] By adopting the above technical proposal, the composite member may be an opaque plastic member mainly for fixing to the clamping member. If the composite member is a transparent plastic member with a printed layer, when light rays pass through the transparent plastic member and illuminate the printed layer, the pattern of the printed layer becomes clearly visible. Furthermore, because of the presence of the transparent plastic member, the pattern exhibits a certain degree of gradation, thereby achieving a systematic integration of decorative function, visual effect, and practical function, and solving the problem that conventional hairpins have monotonous decorative elements and lack visual gradation.

[0011] Selectively, the composite member includes two mounting and fixing layers and a printed layer provided between the two mounting and fixing layers.

[0012] By adopting the above technical proposal, the composite component of the hairpin consists of two mounting and fixing layers and a printed layer provided between them. Light rays are refracted and reflected between the different mounting and fixing layers, producing a unique optical effect that makes the pattern of the printed layer stand out clearly. As a result, the pattern exhibits a certain degree of gradation, and the hairpin has a unique appearance and good decorative effect.

[0013] Selectively, the clamping member includes a first clamping plate, a second clamping plate, and a torsion spring, the first and second clamping plates being connected via a rotating shaft, the torsion spring being fitted onto the rotating shaft and acting on the first and second clamping plates, and the first clamping plate being fixed to one of its mounting layers via an adhesive.

[0014] By adopting the above technical proposal, a classic and reliable mechanical clamping structure is employed, where a torsion spring provides a continuously stable clamping force, ensuring that the hairpin is securely fixed to the hair. The clamping members achieve a rigid connection, preventing shaking or rotation of the clamping members relative to the decorative body, thereby improving the reliability and durability of the product.

[0015] Selectively, the sticker component includes an outer layer, a base layer, and a bottom layer, with the outer layer and bottom layer working together to sandwich and seal the base layer.

[0016] By adopting the above technical proposal, the sticker component employs a structure in which the outer layer and bottom layer cooperate to sandwich and seal the base layer, defining a "sandwich" protective structure. This effectively blocks erosion and wear of the base layer due to water vapor, dust, and physical friction, significantly improving the durability and retention of the base layer, maintaining the decorative effect in like-new condition for a long period of time, and ensuring that light transmittance is not affected.

[0017] Selectively, the outer layer is made from PVC material, the base layer from epoxy resin material, and the bottom layer from PET or PVC material. Both the outer and bottom layers are fitted with character patterns, and the outer and bottom layers are fixed together by high-frequency hot-pressure welding.

[0018] By adopting the above technical proposal, a systematic integration of decorative function, visual effect, and practical function is achieved, solving the problems of conventional hairpins being monotonous, easily falling off, or lacking visual gradation. The outer layer, made from PVC material, is flexible and wear-resistant and can protect the base and bottom layers. The base layer, made from epoxy resin material, provides three-dimensional support and shaping for the character pattern, making the pattern more three-dimensional and elaborate. The bottom layer, made from PET or PVC material, works in cooperation with the outer layer to seal the base layer, preventing the base layer from being affected by external influences. The character patterns on the outer and bottom layers satisfy the aesthetic needs of the target user, enhancing the market appeal and decorative value of the product. High-frequency hot-pressure welding strengthens the connection between the outer and bottom layers, ensuring the sealing and durability of the base layer, and allowing the hairpin's decorative effect to maintain its like-new beauty for a long period of time.

[0019] Selectively, the outer layer is made from PVC material, the bottom layer is made from PVC material, an adhesive layer made from PET or PVC material is placed on the bottom layer, the base layer is set in liquid, decorative components are placed within the base layer, the outer layer and bottom layer are fixed by high-frequency hot-pressure welding, and the bottom layer and adhesive layer are fixed by high-frequency hot-pressure welding.

[0020] By adopting the above technical proposal, the inner and outer layers of the hairpin sticker component are manufactured from PVC material, the bottom layer is also manufactured from PVC material, and an adhesive layer of PET or PVC material is provided, making it easy to apply and use the sticker. The base layer is set to liquid, and decorative components are placed inside. When the user shakes the sticker, the base layer flows, and the pattern changes dynamically due to the refraction of the liquid, greatly increasing interactivity and fun. The outer layer and bottom layer, and the bottom layer and adhesive layer are all fixed by high-frequency hot-pressure welding to ensure structural stability. Physically overlapping the sticker component and the composite component creates a composite visual effect with rich gradation. A torsion spring provides a stable clamping force, and the first clamping plate is rigidly connected to the mounting fixing layer, preventing shaking or rotation of the clamping component. This solves the problems of conventional hairpin decorative elements, which are monotonous, easily fall off, or lack visual gradation.

[0021] Selectively, the liquid that constitutes the base layer is water.

[0022] By adopting the above technical proposal, the base layer of the hairpin sticker material is set to water, and the decorative components within the base layer can flow along with the fluidity of the water. Users can shake the hairpin and see the dynamic changes that occur in the pattern due to the refraction of the liquid, greatly increasing interactivity and fun, and overcoming the drawback that conventional 3D stickers only offer static viewing.

[0023] Selectively, the outer layer is manufactured from PVC material, the base layer from resilient EVC material, and the bottom layer from PET, PVC, or PVC material, and is provided with an adhesive layer. The outer layer and base layer are pre-compounded by adhesive bonding, and the outer layer, base layer, and bottom layer are formed by high-frequency thermocompression bonding.

[0024] By adopting the above technical solution, the decorative function, visual effect and practical function can be systematically integrated by the superimposed composite member, sticker member, and clamping member fixed to the composite member. Thus, the problems of the conventional hairpin's decorative elements being monotonous, prone to falling off, or lacking visual gradation can be solved. By using materials corresponding to the outer layer, base layer, and bottom layer of the sticker member, and through preliminary lamination by adhesion and high-frequency thermocompression forming, the sticker member of the hairpin has excellent elasticity, light transmittance, and stability. And the adhesive layer makes it easy to paste and use the hairpin, enhancing the practicality and aesthetics of the product.

Advantages of the Invention

[0025] To sum up, this application includes at least one of the following beneficial technical effects.

[0026] 1. By physically superimposing the sticker member and the composite member, light passes through the mounting and fixing layer and irradiates the printing layer, producing a rich composite visual effect with gradation, thus solving the problem that the decorative elements of conventional hairpins are monotonous and lack visual gradation.

[0027] 2. The clamping member uses a torsion spring to provide a stable clamping force. By fixing the first clamping plate and the mounting and fixing layer through an adhesive, the shaking or rotation of the clamping member is avoided, solving the problem that the connection between the decorative part and the fixing device of the conventional hairpin is not firm and prone to falling off, and improving the reliability and durability of the product in use.

[0028] 3. By adopting transparent materials for the mounting and fixing layer, the outer layer, base layer, and bottom layer of the sticker member, the smoothness of the light path is ensured, the light and shadow gradation effect of the composite member is fully presented, the blocking of light and shadow or the attenuation of brightness is avoided, and the harmony and maximization of the overall visual effect are realized.

[0030] The present invention will be described in more detail below with reference to Figures 1 to 5.

[0031] (Example 1) A hairpin, referring to Figures 1 and 2, includes a clamping member 3 and an ornament fixedly connected to the clamping member 3.

[0032] The ornament includes a composite member 1, a sticker member 2, and a clamping member 3 provided on the composite member 1. Here, the composite member 1 is an opaque plastic member or a transparent plastic member with a printed layer 102. The sticker member 2 is fixed to the composite member 1 via an adhesive. The clamping member 3 is attached to the composite member 1, so that the hairpin not only has a unique visual effect from the composite member 1 but also a character decoration effect from the sticker member 2, and the clamping member 3 can easily fix the hairpin to the hair. The mounting and fixing layer 101 and the printed layer 102 on the composite member 1 can produce a rich light and shadow effect. The character pattern 6 on the sticker member 2 enhances the aesthetic appeal of the hairpin and avoids many of the drawbacks of conventional hairpin decoration methods.

[0033] The composite member 1 includes a plurality of overlapping mounting and fixing layers 101, and a printed layer 102 is provided on one side of one of the mounting and fixing layers 101.

[0034] The mounting and fixing layer 101 is generally made of a transparent material, such as an acrylic sheet or clear glass, and these materials have good light transmittance. An acrylic sheet mounting and fixing layer 101 is lightweight, inexpensive, and has a certain degree of flexibility. A clear glass mounting and fixing layer 101 has better light transmittance, a stronger texture, and can exhibit a sharper light and shadow effect. By overlapping multiple mounting and fixing layers 101, light rays are refracted and reflected between different mounting and fixing layers 101, creating a unique optical effect.

[0035] The printing layer 102 can be printed with various patterns, characters, etc., using a printing process, which may be conventional ink printing, UV printing, etc. Ink printing is inexpensive and suitable for large-scale production. UV printing produces more vivid colors and stronger adhesion. The printing layer 102 is provided on one side of one of the mounting and fixing layers 101, and when light passes through the mounting and fixing layer 101 and shines on the printing layer 102, the pattern on the printing layer 102 becomes clearly visible, and the overlapping of the mounting and fixing layers 101 causes the pattern to exhibit a certain degree of gradation.

[0036] The clamping member 3 includes a first clamping plate 301, a second clamping plate 302, and a torsion spring 303.

[0037] Both the first clamping plate 301 and the second clamping plate 302 have connecting support plates integrally formed on them, and the rotating shaft 304 connects them by passing through through holes in the connecting support plates on the first clamping plate 301 and the second clamping plate 302. By connecting the first clamping plate 301 and the second clamping plate 302 via the rotating shaft 304, they can rotate around the rotating shaft 304 to perform opening and closing operations.

[0038] The torsion spring 303 is fitted onto the rotating shaft 304 and acts on the first clamping plate 301 and the second clamping plate 302, applying a biasing force to the first clamping plate 301 and the second clamping plate 302 so that their ends away from the rotating shaft 304 move closer together. The first clamping plate 301 and one of its mounting fixing layers 101 are fixed together via an adhesive.

[0039] The first clamping plate 301 and the second clamping plate 302 are generally made of metal or plastic. Clamping plates made of metal have high strength and good durability. Clamping plates made of plastic are lightweight and low cost. The adhesive may be a strong glue to firmly fix the first clamping plate 301 to the mounting fixing layer 101 and to ensure the connection stability between the clamping member 3 and the composite member 1.

[0040] A mounting groove 4 is provided in one of the mounting and fixing layers 101, and the first clamping plate 301 is inserted into the mounting groove 4. The role of the mounting groove 4 is to provide a mounting position for the first clamping plate 301 and to make the connection with the mounting and fixing layer 101 stronger. The shape and size of the mounting groove 4 can be adapted to the first clamping plate 301, and the depth and width of the mounting groove 4 can be designed to match the dimensions of the first clamping plate 301.

[0041] An opening is provided in the first clamping plate 301, and a boss 5 extending into the opening is integrally formed within the mounting groove 4. The cooperation of the boss 5 and the opening further enhances the connection strength between the first clamping plate 301 and the mounting fixing layer 101. After the first clamping plate 301 is inserted into the mounting groove 4, the boss 5 extends into the opening, serving to restrict its position and fix it in place, preventing the first clamping plate 301 from coming out of the mounting groove 4 during use.

[0042] The sticker member 2 includes an outer layer 201a, a base layer 202a, and a bottom layer 203a. The outer layer 201a and the bottom layer 203a cooperate to sandwich and seal the base layer 202a. The outer layer 201a, base layer 202a, and bottom layer 203a are also typically made of transparent material to ensure the light transmittance of the entire sticker member 2, thereby better representing the light and shadow effect of the composite member 1.

[0043] The outer layer 201a can be made of a transparent PVC film material, which has a certain degree of flexibility and abrasion resistance and can protect the base layer 202a and bottom layer 203a. The outer layer 201a is also provided with a character pattern. The character pattern can be created by printing, color painting, or other methods. Character patterns created by printing offer high precision and are suitable for large-scale production, while character patterns created by color painting are more artistic and individualistic.

[0044] The base layer 202a is hard, and its shape matches the character pattern. The base layer 202a can be made of epoxy resin, and the plastic base layer 202a has high hardness and is resistant to deformation. Furthermore, the outer layer 201a and bottom layer 203a are coated onto the outer surface of the base layer 202a by high-frequency hot-pressure welding.

[0045] The bottom layer 203a uses a transparent PVC film similar to the outer layer 201a, sealing the base layer 202a together with the outer layer 201a and preventing the base layer 202a from being affected by external factors.

[0046] The implementation principle of the embodiment of the present invention is as follows: When in use, the hairpin is firmly fixed to the hair by the clamping member 3 (the first clamping plate 301 and the second clamping plate 302 are clamped by a torsion spring 303). When ambient light or a specific light source is shone on the hairpin, the light rays first pass through the sticker member 2. The transparent material of the outer layer 201 of the sticker member 2 and the character pattern 6 on it stand out against the light-transmitting background, but the base layer 202, which has a constant hardness and whose outer shape matches the pattern, provides the character pattern 6 with a three-dimensional contour and support, preventing deformation of the pattern. Subsequently, the light rays enter the composite member 1 and undergo multiple refractions and reflections as they sequentially traverse the multiple mounting and fixing layers 101. The pattern of the printed layer 102 located on one side of the mounting and fixing layer 101 is projected, diffused, and superimposed with the optical effects of the other mounting and fixing layer 101 under the influence of light rays passing through that layer and the other mounting and fixing layer 101, thereby creating a visually rich, deep, and tonally rich light and shadow transformation effect. Finally, the concrete character pattern 6 of the sticker member 2 and the abstract light and shadow effect of the composite member 1 overlap spatially, complementing each other and together forming a unique, beautiful, and dynamic visual decoration. Throughout the entire structure, the clamping member 3 is firmly connected to the composite member 1 by adhesive and the mechanical locking of the mounting groove 4 and boss 5, ensuring overall structural stability and reliability during the attachment and use of the hairpin.

[0047] The embodiments of this specific model are all preferred embodiments of the present application and do not limit the scope of protection of the present application. Here, the same parts are indicated by the same reference numerals. Therefore, equivalent variations based on the structure, shape, and principle of the present application should all be included within the scope of protection of the present application.

[0048] (Example 2) Referring to Figure 4, the difference from Example 1 is that the outer layer 201b is made from PVC material. The bottom layer 203b is made from PVC material, and an adhesive layer 6 made from PET or PVC material is bonded to its surface. At the same time, the outer layer 201b and the bottom layer 203b are fixed by high-frequency hot-pressure welding, and the bottom layer 203b and the adhesive layer 6 are fixed by high-frequency hot-pressure welding.

[0049] Furthermore, the base layer 202b is set to a liquid and fills a cavity surrounded by the outer layer 201b and the bottom layer 203b, with decorative components placed within the liquid base layer 202b. Here, the liquid constituting the base layer 202b is water.

[0050] The implementation principle of the embodiment of this invention is as follows: A complete water-in 3D sticker is formed by integrally combining the outer layer 201b, base layer 202b, bottom layer 203b, and adhesive layer 6. The outer layer 201b provides a window for observing the flow and pattern of the base layer 202b, the presence of the base layer 202b brings about a dynamic effect, the pattern on the bottom layer 203b enhances the aesthetics and sense of gradation, and the adhesive layer 6 facilitates the application and use of the sticker. When using the sticker, the user can shake the sticker to cause the base layer 202b to flow, and observe the dynamic changes that occur in the pattern due to the refraction of the liquid, greatly increasing interactivity and fun, overcoming the drawback that conventional 3D stickers only offer static viewing.

[0051] (Example 3) Referring to Figure 5, the difference from Example 1 is that the outer layer 201c is manufactured from PVC material. The base layer 202c is manufactured from elastic EVA material, and the outer layer 201c and base layer 202c are pre-compounded by adhesive. The bottom layer 203c is manufactured from PET or PVC material and is provided with an adhesive layer 6. At the same time, the outer layer 201c, base layer 202c, and bottom layer 203c are formed by high-frequency thermocompression bonding.

[0052] The implementation principle of the embodiment of the present invention is as follows: First, a pattern is printed on a PVC film to form an outer layer 201c. Next, the outer layer 201c is pre-composited to the surface of a base layer 202c made of EVA material. Next, the base layer 202c is attached to the surface of a bottom layer 203c made of PET or PVC material. Then, by performing EVA molding by high-frequency thermocompression bonding, the base layer 202c is tightly connected to the outer layer 201c and the bottom layer 203c, respectively. Finally, an adhesive layer 6 is placed on the back surface of the bottom layer 203c.

[0053] The embodiments of this specific model are all preferred embodiments of the present application and do not limit the scope of protection of the present application. Here, the same parts are indicated by the same reference numerals. Therefore, equivalent variations based on the structure, shape, and principle of the present application should all be included within the scope of protection of the present application.
