Abstract
Description
Technical Field
[0001] This invention belongs to the field of daily necessities technology, more specifically, comb technology. It particularly relates to a comb with dog-tooth comb teeth embedded in a wooden fixture and its flexible leather covering. By incorporating the properties of different materials, this invention innovates the comb's structure, manufacturing process, and functionality, aiming to enhance user experience and comb quality. Background Art
[0002] The existing comb products in this field have the following technical problems: First, the comb tooth structure design is defective. For example, the edges of wooden or metal comb teeth are sharp, which makes it difficult to fit the curved surface of the human scalp and easily causes scalp damage during combing. Second, the comb material performance is insufficient. Traditional hard plastic or ordinary wood not only has a poor texture, but also easily wears out and cracks after long-term use, which affects the service life of the product. Third, the function is relatively single. The existing comb tooth structure cannot meet the user's diverse needs for scalp massage, hair care, etc. Fourth, there is insufficient material innovation. There is no comb product on the market that organically combines natural dog tooth with leather or wood materials. There is a lack of fusion application of natural material properties and traditional aesthetics. Therefore, there is an urgent need for a comb product with improvements in material combination, comb tooth structure and function integration to solve the above technical problems. Summary of the Invention
[0003] Purpose of the invention: In view of the problems of existing combs such as single function, lack of innovation in material combination, and insufficient texture, the present invention provides a combination comb with dog-tooth comb teeth embedded in a wooden fixed body and its flexible leather covering structure. Through special material selection and structural design, the use time of the comb is increased, the use experience of the comb is enriched, and the technical effect of improving decorative function and aesthetic recognition is achieved.
[0004] As an optimal technical solution, the dog tooth comb teeth have their root body geometric center axis perpendicular to the side plane in the long axis direction of the fixed body, the side plane is perpendicular to the cross section in the width direction of the fixed body, and the side plane is in the short side direction of the cross section in the width direction of the fixed body, and the side plane is the side surface in the length direction of the fixed body; the comb teeth are installed by using a mortise and tenon structure, the tenon length is 6mm, the width is 4mm, and the radial interference tolerance with the mortise of the fixed body is +0.01mm to +0.03mm. Through the control of the fitting accuracy and the axis verticality (tolerance ≤0.05mm), the installation verticality and the anti-fatigue stability of the structure are ensured, the extension direction of the tooth tip of each comb tooth is perpendicular to the length direction of the fixed body, and the extension direction of the tooth tip of each comb tooth is consistent, so that the comb teeth form an arc-shaped massage surface and a tooth tip combing surface, achieving the technical effect of the dual functions of hair combing and scalp massage.
[0005] As a preferred option, the fixed body of the present invention adopts natural high-quality wood as the base material; the present invention innovatively proposes a technical solution for the independent interlocking of comb teeth, realizing the innovation of the modular assembly structure of the comb tool. The comb teeth are mechanically connected to the fixed body in a single-unit independent interlocking manner through a mortise and tenon structure combined with a gluing process. This process enables each comb tooth to act as an independent functional unit, forming a precisely adapted connection structure with the fixed body, significantly improving the connection stability and overall durability between the comb teeth and the fixed body.
[0006] As an alternative embodiment, when the comb teeth need to be replaced, a special grooving mechanical equipment is used to perform grooving at the corresponding position of the fixed body in the same plane as the original installation mortise and perpendicular to the direction of the original mortise. By utilizing the independent interlocking characteristics of the mortise and tenon structure, a cross-interlocking channel is formed by the transverse grooving and the original longitudinal mortise, which can realize the convenient disassembly and replacement of a single comb tooth, effectively improving the maintenance convenience and service life of the product.
[0007] As a preferred solution, the present invention adopts a combination design in which the fixed body is completely covered with a flexible leather material, and utilizes the natural white color of the natural dog teeth and the dark flexible leather material to produce a clear color contrast, effectively solving the technical problem of the single decorative property of existing products, and realizing the decorative function and the technical effect of improving product recognition.
[0008] By implementing the above technical solution, the present invention has the following beneficial effects:
[0009] The comb teeth are made of natural dog teeth. The enamel structure on the smooth surface of the natural dog teeth is harder than the surface of traditional materials such as wood and ABS plastic. It can reduce the contact area and friction resistance with the hair, and reduce the pulling damage to the hair during combing.
[0010] The comb teeth are made of natural dog teeth, which have a Vickers hardness of 300-500HV, significantly higher than natural ox horn (150-200HV) and ABS plastic (80-120HV). Based on this hardness advantage, under the same operating conditions, the wear rate of natural dog teeth is lower than that of the other two materials, effectively improving the structural stability and functional durability of the comb teeth during long-term use.
[0011] The present invention achieves multiple functional optimizations through the innovative combination of natural dog tooth comb teeth and flexible leather material: first, the comb body composed of flexible leather material improves the grip fit and operating comfort; second, during long-term use, the surface color of this material combination will show a predictable gradual change with the length of use due to natural oxidation, surface friction and the effects of environmental media, forming a natural patina effect that is identifiable from the initial state. This change process is stable and irreversible, and does not affect the mechanical properties of the material itself and the product function, giving the product unique time-sensitive characterization characteristics.
[0012] The animal-derived materials used in this patent strictly comply with the requirements of laws and regulations such as the "Animal Epidemic Prevention Law of the People's Republic of China" and the "Animal Quarantine Management Measures" and relevant industry standards. The materials used are taken from non-nationally protected animals such as canine teeth, and the species classification complies with the provisions of the "National List of Key Protected Wild Animals", ensuring that the source is legal, quarantine is compliant, and does not involve protected species.

Figure 4 This is a schematic diagram of the main viewing direction of Example 2 of the present invention.
[0014] Specific implementation: The present invention includes two embodiments: Embodiment 1 adopts a wooden fixed body (2), fixes the dogtooth comb teeth (1) thereon, and then uses a coating and gluing process to make the flexible leather material (3) tightly cover the fixed body (2) to form a coating structure; Embodiment 2 uses a comb body made of high-quality natural hardwood as the fixed body, and realizes a stable connection with the comb teeth (1) through a mortise and tenon gluing process; Both embodiments use a mortise and tenon structure to realize a stable connection between the comb teeth (1) and the base material; Embodiment 1 improves the flexibility and grip comfort of the product by combining a wooden fixed body (2) with a flexible leather material (3) coating design; Embodiment 2 selects a wooden fixed body (2) material to strengthen the overall structural strength of the comb body.
[0015] Example 1: A combined comb with dog-tooth comb teeth embedded in a wooden fixed body and its flexible leather covering structure.
[0016] The comb teeth (1) are composed of natural dog teeth and are arranged in a linear array in an orderly manner. The tips of the comb teeth (1) extend in the same direction and are perpendicular to the array reference line, ensuring that the comb teeth (1) are arranged in a regular manner.
[0017] The roots of the comb teeth (1) are formed by using a special precision grinding device, and a dovetail mortise and tenon structure is constructed at the root portion through a professional grinding process. The dimensional accuracy of the tenon is controlled within ±0.03mm to ensure the interference fit requirement with the connecting piece.
[0018] High-quality natural hardwood that has been dried (moisture content ≤ 12%) is selected as the fixing body (2), and a linear positioning adaptation groove is milled on the surface of the fixing body (2) using a milling machine. The groove depth accuracy reaches ±0.1mm, and the groove width forms a stable mortise and tenon joint connection structure with the tenon of the comb teeth (1).
[0019] The tenons of the comb teeth (1) formed by cutting are evenly coated with adhesive, and then the tenons are embedded in the grooves of the fixed body (2) that have been grooved and coated with glue to form a rough comb; the gaps between the adjacent comb teeth (1) in the grooves of the fixed body (2) are filled with special wooden strips to ensure that the comb teeth structure is stable and the overall flatness.
[0020] A precision punching process is used to open through holes on the surface of the flexible leather material (3) with the same number and size as the comb teeth (1), and then one side of the flexible leather material (3) is coated with glue.
[0021] By precisely inserting the comb teeth (1) on the fixed body (2) into the corresponding through holes from the side of the glue-coated surface of the flexible leather material (3), and utilizing the adhesive force of the glue and the limiting effect of the through holes, the flexible leather material (3) is tightly attached to and covers the gaps between the comb teeth (1), thereby completing the covering structure of the flexible leather material (3) on the fixed body (2).
[0022] A full covering process of a flexible leather material (3) is adopted. After the flexible leather material (3) is tightly covered on the surface of a fixed body (2), the leather edge is repaired and locked (such as sewing, gluing, etc.) to achieve complete covering and packaging of the comb body.
[0023] The present invention solves the problem of the difficulty in achieving both strength and flexibility of a traditional comb made of a single material by using a composite structure in which linear array dog-tooth comb teeth (1) are embedded in a wooden fixed body (2) and an outer layer is covered with a flexible leather material (3). When the fixed body (2) is miniaturized, the flexible leather material (3) is used as the main body to improve the flexibility of the comb body and optimize the grip texture. When the fixed body (2) is designed with the same size, the flexible leather material (3) enhances the waterproofness of the structure.
[0024] Example 2: A combined comb in which dog-tooth comb teeth are embedded in a wooden comb body.
[0025] The comb teeth (4) are composed of natural dog teeth and are arranged in a linear array in an orderly manner. The tips of the dog teeth extend in the same direction and are perpendicular to the array reference line, ensuring that the comb teeth (4) are arranged in a regular manner.
[0026] The roots of the comb teeth (4) are formed by using a special precision grinding device, and a dovetail mortise and tenon structure is constructed at the root portion through a professional grinding process. The dimensional accuracy of the tenon is controlled within ±0.03mm to ensure the interference fit requirement with the connecting piece.
[0027] A comb body (5) made of high-quality natural hardwood that has been dried (with a moisture content of ≤12%) is selected as the fixing body of the comb teeth (4). A linear positioning adaptation groove is milled on the surface of the comb body (5) using a milling machine. The groove depth accuracy reaches ±0.1mm, and the groove width forms a stable mortise and tenon joint connection structure with the tenon of the comb teeth (4).
[0028] First, the tenons of the comb teeth (4) that have been cut and formed are evenly coated with adhesive, and then they are embedded in the grooves of the comb body (5) that have been grooved and coated with glue; the gaps between the adjacent comb teeth (4) in the grooves of the comb body (5) are filled with special wooden strips, and then the comb is polished as a whole with a polishing machine to ensure that the comb teeth (4) are structurally stable and flat as a whole.
