Description

Technical Field

[0001] This utility model relates to the field of hat rack technology, and in particular to a hat fixing device for outdoor use. Background Technology

[0002] In outdoor travel scenarios, hats, as essential equipment for sun and rain protection, often need to be temporarily stored when not in use. Because they preserve the hat's shape and ensure future use, storage and securing devices have become practical accessories for outdoor activities. Traditional hat storage and securing methods mostly involve folding, hanging with universal hooks, or using spring clips, which have significant drawbacks: Firstly, folding the hat and stuffing it into a backpack or pocket can easily cause the brim to deform and the fabric to wrinkle, especially causing irreversible structural damage to hard-top baseball caps; simple hooks, due to their fixed opening, cannot accommodate brims of different thicknesses, and the hat can easily fall off during bumpy travel, requiring repeated checks; secondly, while existing spring clips can secure the brim, their clamping force is not adjustable, and excessive force can leave indentations on the hat surface, and they lack portable hanging designs, making it difficult to meet the needs of diverse outdoor scenarios.

[0003] The above issues seriously affect the user experience: improper storage methods not only damage the original shape of the hat, reducing its protective function and aesthetics, but may also disrupt the travel rhythm due to the risk of it falling off, and are not suitable for high-frequency outdoor scenarios such as backpack attachments and tent side hanging.

[0004] Therefore, this utility model provides a hat fixing device mainly used for outdoor travel. Through the cooperation of an adaptive clamping mechanism and a suspension system, it effectively solves the problems of damage-free storage and portable stability of hats in outdoor scenarios. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a hat fixing device with a simple structure that solves the problems of damage-free storage and portable stability of hats in outdoor scenarios.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A hat fastening device, comprising:

[0008] Clamping elements;

[0009] An elastic element is rotatably connected to the clamping element for cooperating with the clamping element to form a clamping space;

[0010] An adjusting element is used to adjust the clamping force generated by the clamping space;

[0011] The connecting element, the clamping element having a first mounting structure, and the elastic element having a second mounting structure, the first mounting structure and the second mounting structure being rotatably connected through the connecting element, so that the elastic element is rotatably connected to the clamping element.

[0012] As an improvement of this utility model, the clamping element is further provided with a first clamping part, and the elastic element is further provided with a second clamping part and a deformation adjustment part. The first clamping part and the second clamping part abut against each other and generate clamping force through the deformation of the elastic element. The adjustment element drives the deformation adjustment part to move to change the degree of deformation of the elastic element, thereby adjusting the clamping force between the first clamping part and the second clamping part. The adjustment element is provided with an abutting end and a threaded adjustment part. The deformation adjustment part is provided with a mounting through hole. The clamping element is further provided with a threaded receiving part. The threaded adjustment part passes through the mounting through hole and is threadedly connected to the threaded receiving part. The abutting end abuts against the side of the deformation adjustment part away from the clamping element. The adjustment element rotates the threaded adjustment part to make the threaded adjustment part axially displace in the threaded receiving part, thereby driving the abutting end, and then driving the deformation adjustment part closer to or away from the clamping element, thereby adjusting the degree of deformation of the elastic element, and finally adjusting the clamping force between the first clamping part and the second clamping part.

[0013] As an improvement of this utility model, it also includes a retaining ring. The adjusting element is also provided with a mounting groove. When the axial position of the mounting groove passes through the mounting through hole, the retaining ring is engaged with the mounting groove so that the adjusting element is connected to the elastic element. The retaining ring is an open-type circular ring structure and is made of manganese steel.

[0014] As an improvement of this utility model, the abutting end is provided with radially distributed support ribs, which are spaced apart along the circumferential direction.

[0015] As an improvement of this utility model, the clamping element is provided with an anti-slip pad layer on the side near the elastic element, and the anti-slip pad layer is made of a material with a high coefficient of friction.

[0016] As an improvement to this utility model, a decorative element is also included, which is fixedly connected to the surface of the adjusting element and / or the clamping element.

[0017] As an improvement of this utility model, it also includes a strap connecting assembly, which includes a connecting strap and a fixing member. The clamping element is further provided with a strap mounting part, and the connecting strap is connected to the strap mounting part through the fixing member.

[0018] As an improvement of this utility model, the hanging strap connecting assembly further includes a connecting ring, which is connected to the connecting strap through the fixing member, and the connecting strap is made of a flexible material.

[0019] As an improvement of this utility model, the elastic element has an elastic modulus in the range of 190-210 GPa and can provide a clamping force of 5-15 N.

[0020] As an improvement to this utility model, the number of supporting ribs is 8-12, and they are evenly distributed along the circumference.

[0021] The beneficial effects of this utility model are as follows: Through the above-described structure, the adjusting element can precisely control the clamping force generated by the clamping space within a reasonable range during use. This ensures stable clamping of hat brims made of different materials while preventing excessive force from leaving indentations on the hat surface, completely solving the problem of non-destructive fixing caused by the non-adjustable clamping force of traditional spring clips. The rotatable connection structure between the elastic element and the clamping element can automatically adjust the opening angle according to the thickness of the brim, allowing the clamping space to adapt to various hat types such as hard-top baseball caps and soft-brimmed sun hats, effectively solving the compatibility limitations caused by universal hook openings. The stable clamping cooperation formed by the clamping element and the elastic element, combined with the portable hanging design of the device itself, can easily achieve reliable fixing in high-frequency outdoor scenarios such as backpack hanging and tent side hanging, avoiding the risk of falling off during bumpy travel. Therefore, this device can maintain the original shape and protective function of the hat while eliminating the need for users to repeatedly check the fixing status, significantly improving the convenience and safety of hat storage during outdoor travel, fully adapting to diverse outdoor scenario needs, and thus enhancing the user experience.

[0035] Reference Figures 1 to 9 A hat fastening device, comprising:

[0036] Clamping element 100;

[0037] An elastic element 200 is rotatably connected to the clamping element 100 and is used to cooperate with the clamping element 100 to form a clamping space;

[0038] Adjustment element 300 is used to adjust the clamping force generated by the clamping space.

[0039] With the above-mentioned structure, the adjusting element 300 can precisely control the clamping force generated by the clamping space within a reasonable range during use. This ensures stable clamping of hat brims made of different materials while avoiding excessive force that could leave indentations on the hat surface. It completely solves the problem of non-destructive fixing caused by the non-adjustable clamping force of traditional spring clips. The rotatable connection structure between the elastic element 200 and the clamping element 100 can automatically adjust the opening and closing angle according to the thickness of the hat brim, making the clamping space adaptively adaptable to various hat types such as hard-top baseball caps and soft-brimmed sun hats. The clamping element 100 serves as the basic structure of the device. Together with the elastic element 200 rotatably connected to it, they form a space for clamping the hat. The elastic element 200's characteristics are used to initially clamp and fix the hat. The adjusting element 300 can adjust the clamping force generated in the clamping space. By changing the magnitude of the clamping force, the device can adapt to hats of different materials and thicknesses, ensuring the stability of the clamping and preventing the hat from falling off during clamping. It can also prevent damage to the hat due to excessive clamping force, thereby improving the device's versatility and reliability.

[0040] In this embodiment, a connecting element 400 is also included. The clamping element 100 is provided with a first mounting structure 110, and the elastic element 200 is provided with a second mounting structure 210. The first mounting structure 110 and the second mounting structure 210 are rotatably connected through the connecting element 400, so that the elastic element 200 is rotatably connected to the clamping element 100. With the above structure, in use, the connecting element 400, by cooperating with the first mounting structure 110 of the clamping element 100 and the second mounting structure 210 of the elastic element 200, achieves a rotatable connection of the elastic element 200 relative to the clamping element 100. This structural design ensures that the elastic element 200 can rotate flexibly around the connection point during operation, thereby forming a dynamically adjustable clamping space together with the clamping element 100, and also improves the assembly efficiency and structural stability of the device through a standardized mounting structure. Furthermore, the rotatable connection provides a structural basis for the precise control of the clamping force by the subsequent adjustment element 300, enabling the elastic element 200 to deform accordingly according to adjustment requirements, thereby achieving reliable fixation of different types of hats and further improving the user experience.

[0041] In this embodiment, the clamping element 100 is further provided with a first clamping part 120, and the elastic element 200 is further provided with a second clamping part 220 and a deformation adjustment part 230. The first clamping part 120 and the second clamping part 220 abut against each other and generate clamping force through the deformation of the elastic element 200. The adjustment element 300 adjusts the degree of deformation of the elastic element 200 through the deformation adjustment part 230, thereby adjusting the magnitude of the clamping force between the first clamping part 120 and the second clamping part 220. With the above-described structure, in use, the precise control of the clamping force is achieved through the coordinated action of the first clamping part 120, the second clamping part 220, and the deformation adjustment part 230: the first clamping part 120 and the second clamping part 220 form a stable abutment structure under the deformation of the elastic element 200, providing a basic clamping force for the hat; the deformation adjustment part 230, as the point of action of the adjustment element 300, converts the adjustment action into a controllable deformation of the elastic element 200, thereby changing the force between the two clamping parts. This structure utilizes the mechanical properties of elastic materials to achieve adaptive clamping, and expands the applicability of the device through a mechanical adjustment mechanism, enabling the device to be personalized according to the differences in hat material and size, ensuring the fixing effect while avoiding damage to the hat, fully embodying the unity of functionality and reliability in mechanical design.

[0042] In this embodiment, the adjusting element 300 is provided with an abutting end 310 and a threaded adjusting part 320, the deformation adjusting part 230 is provided with a mounting through hole 231, and the clamping element 100 is also provided with a threaded receiving part 130. The threaded adjusting part 320 passes through the mounting through hole 231 and is threadedly connected to the threaded receiving part 130. The abutting end 310 and the deformation adjusting part 230 are kept in contact. The adjusting element 300 causes the threaded adjusting part 320 to move axially in the threaded receiving part 130 by screwing the threaded adjusting part 320, thereby driving the abutting end 310, and then driving the deformation adjusting part 230 to move closer to or away from the clamping element 100, thereby adjusting the degree of deformation of the elastic element 200, and finally adjusting the magnitude of the clamping force between the first clamping part 120 and the second clamping part 220. With the above-described structure, the adjustment mechanism achieves precise control of the clamping force through threaded transmission during use: the engagement of the threaded adjustment part 320 and the threaded receiving part 130 converts rotational motion into axial displacement, enabling the abutting end 310 to push the deformation adjustment part 230 to move linearly; the mounting through hole 231 provides a movement path for the adjustment element 300 and ensures the stability of force transmission through a limiting effect. This design utilizes the self-locking characteristics of the threaded pair to achieve stable clamping force maintenance. The deformation degree of the elastic element 200 can be precisely controlled by tightening, thereby achieving stepless adjustment of the clamping force between the first clamping part 120 and the second clamping part 220. This structure transforms simple mechanical motion into a reliable force control mechanism, meeting the differentiated clamping force requirements under different usage scenarios, and improving the assemblability and maintenance convenience of the device through standardized threaded connections, fully demonstrating the efficient combination of motion conversion and functional realization in mechanical design.

[0043] In this embodiment, a retaining ring 500 is also included. The adjusting element 300 is further provided with a mounting groove 330. When the axial position of the mounting groove 330 passes through the mounting through hole 231, the retaining ring 500 engages with the mounting groove 330, so that the adjusting element 300 is connected to the elastic element 200. With the above structure, in use, the retaining ring 500 cooperates with the mounting groove 330 of the adjusting element 300 to achieve a movable connection between the adjusting element 300 and the elastic element 200. When the threaded adjusting part 320 of the adjusting element 300 passes through the mounting through hole 231 of the deformation adjusting part 230, the retaining ring 500 engages with the mounting groove 330 to form an axial limit, which allows the adjusting element 300 to make axial displacement under threaded drive, while preventing it from disengaging from the elastic element 200. This structural design ensures that the adjusting element 300 can effectively transmit the adjusting force while solving the connection stability problem during the axial movement of the threaded pair. This allows the adjusting action to be reliably converted into the deformation of the elastic element 200, thereby achieving precise control of the clamping force. The connection method of the retaining ring 500 combines detachability with structural strength, facilitating assembly and maintenance of the device while ensuring the reliability of the connections between components during frequent adjustments. This reflects the precise matching of connection method selection and functional requirements in mechanical design.

[0044] In this embodiment, the abutment end 310 is provided with radially distributed support ribs 311, which are spaced apart along the circumferential direction. Through this structural design, during use, the radial distribution and circumferentially spaced arrangement of the support ribs 311 at the abutment end 310 achieves uniform force transmission and optimized support stability: the radial layout allows the support ribs 311 to disperse the axial force of the adjusting element 300 to the contact surface of the deformation adjusting part 230, avoiding material damage caused by localized stress concentration; the circumferentially spaced arrangement ensures support rigidity while reducing structural weight, conforming to lightweight design principles. This structure effectively prevents relative sliding between the abutment end 310 and the deformation adjusting part 230 during the screwing adjustment process, ensuring that the adjusting force is converted into effective deformation of the elastic element 200, thereby improving the accuracy and reliability of the clamping force adjustment. The distribution of the support ribs 311 reflects the synergistic consideration of structural optimization and functional requirements in mechanical design.

[0045] In this embodiment, the retaining ring 500 is an open-type circular ring structure. With this structure, the retaining ring 500, in use, adopts an open-type circular ring structure, achieving a stable connection between the adjusting element 300 and the elastic element 200 while also ensuring ease of assembly: the open design allows it to open radially through elastic deformation, facilitating quick insertion into the groove after passing through the mounting through-hole 231 at the axial position of the mounting groove 330, thus completing the connection and fixation; the circular ring structure ensures uniform circumferential contact between the retaining ring and the inner wall of the mounting groove 330, providing reliable axial limiting and preventing the adjusting element 300 from disengaging from the elastic element 200 during movement. This structure simplifies the assembly process by utilizing the open characteristic, allowing installation without complex tools, while the integrity of the circular ring ensures connection strength, enabling the axial displacement of the adjusting element 300 to stably act on the deformation adjustment part 230, providing structural support for precise adjustment of the clamping force. The open-type circular ring design fully balances assembly efficiency and connection reliability, reflecting the optimized combination of structural form and practical function in mechanical design.

[0046] In this embodiment, the retaining ring 500 is made of manganese steel. The selection of manganese steel for the retaining ring 500 primarily ensures connection reliability and structural durability: manganese steel possesses high strength, hardness, and excellent elastic deformation capability. During assembly, it can smoothly engage with the mounting groove 330 through the elastic expansion of the open structure. After assembly, it can also form a stable clamping force due to the elastic recovery force of the material, ensuring a tight fit between the retaining ring 500 and the mounting through-hole 231 of the adjusting element 300, effectively resisting axial forces generated during adjustment and preventing loosening or detachment. Simultaneously, the good wear resistance and fatigue resistance of manganese steel prevent a decline in connection function due to material failure after long-term use, thereby extending the service life of the entire device. This material selection, combined with the open-type ring structure, further enhances connection strength and reliability from a material performance perspective while satisfying assembly convenience.

[0047] In this embodiment, the depth of the mounting groove 330 is 0.3-0.7 mm. With the above structural design, the depth of the mounting groove 330, set at 0.3-0.7 mm, is a precise design that balances connection reliability and structural strength. This depth range ensures sufficient axial embedment after the retaining ring 500 is engaged, allowing the retaining ring 500 to form a stable mechanical engagement with the inner wall of the mounting groove 330. This effectively resists the tensile or pushing forces generated by the adjusting element 300 during axial movement, preventing the retaining ring 500 from accidentally dislodging and ensuring the connection stability between the adjusting element 300 and the elastic element 200. Simultaneously, this depth avoids weakening the local structural strength of the adjusting element 300 due to an excessively deep groove—an excessively deep mounting groove 330 may cause stress concentration in the adjusting element 300 under load, even leading to breakage; while an excessively shallow groove cannot provide sufficient engagement space for the retaining ring 500, easily leading to connection failure.

[0048] A depth range of 0.3-0.7 mm establishes a balance between the effective engagement of the retaining ring 500 and the structural integrity of the adjusting element 300 itself. This ensures both the reliable implementation of the retaining ring 500's limiting function and the stable transmission of axial force to the elastic element by the adjusting element 300, providing structural parameter support for the safe operation of the clamping force adjustment mechanism.

[0049] In this embodiment, the clamping element 100 is provided with an anti-slip pad 140 on the side near the elastic element 200, and the anti-slip pad 140 is made of a material with a high coefficient of friction. With this structure, during use, the anti-slip pad 140 on the side of the clamping element 100 near the elastic element 200 achieves multiple functions through the properties of the high coefficient of friction material: on the one hand, when the first clamping part 120 and the second clamping part 220 cooperate to clamp the hat, the anti-slip pad 140 can increase the friction with the hat surface, effectively preventing the hat from sliding relative to the surface during clamping, significantly improving the stability of the fixation, especially suitable for smooth materials or hats that are prone to sliding; on the other hand, the high coefficient of friction material has a certain elastic buffering effect, which can reduce the direct pressure of the clamping force on the hat surface, avoiding wear or indentations caused by rigid contact, and protecting the hat. This design optimizes the clamping effect and safety of the device by combining material properties and structural position without affecting the clamping force adjustment function. It makes the fixing process both reliable and gentle, reflecting careful consideration of the adaptability to hats of different materials.

[0050] In this embodiment, the elastic element 200 is made of manganese steel or stainless steel. Through the above structural design, the manganese steel sheet possesses excellent elastic deformation capability and fatigue strength. When used in conjunction with the clamping element 100 to form a clamping space, it can generate a continuous and controllable clamping force through stable deformation. Furthermore, it is not prone to plastic deformation during repeated adjustments and use, ensuring the long-term stability of the clamping force. The stainless steel sheet, characterized by good corrosion resistance and structural strength, can adapt to complex environments such as humidity and dust, avoiding elastic failure due to corrosion. Simultaneously, its moderate elastic modulus can meet the adjustment requirements of different clamping forces. Both materials can effectively cooperate with the adjustment action of the adjusting element 300, accurately responding to the force changes of the deformation adjustment part 230, thereby achieving dynamic control of the clamping force between the first clamping part 120 and the second clamping part 220. In addition, the balance between rigidity and elasticity of the metal sheet material ensures structural stability during clamping and avoids excessive compression of the cap. Together with the anti-slip pad layer 140, it enhances the reliability and adaptability of the device, demonstrating a high degree of fit between material selection and functional requirements.

[0051] In this embodiment, a decorative element 600 is also included, which is fixedly connected to the surface of the adjusting element 300 and / or the clamping element 100. With the above structure, in use, the decorative element 600, fixedly connected to the surface of the adjusting element 300 and / or the clamping element 100, primarily serves to beautify the appearance of the device and enhance its attractiveness. It not only conceals the mechanical structural details of the device, making the overall shape more aesthetically pleasing, but also allows for diverse designs (such as different patterns or shapes) to meet users' personalized decorative needs, thus enhancing the product's market competitiveness. Simultaneously, the fixed connection method of the decorative element does not interfere with the normal operation of core components such as the adjusting element and the clamping element, achieving a combination of practical and aesthetic value while ensuring the device's functionality is not affected. In this embodiment, two decorative elements 600 are provided, respectively fixedly connected to the outer surfaces of the adjusting element 300 and the clamping element 100, to beautify the hat fixing device.

[0052] In this embodiment, a strap connecting assembly 700 is also included. The strap connecting assembly 700 includes a connecting strap 710 and a fixing member 720. The clamping element 100 is further provided with a strap mounting portion 150, and the connecting strap 710 is connected to the strap mounting portion 150 through the fixing member 720. With the above structure, in use, the strap mounting portion 150 serves as a structural extension of the clamping element 100, providing a reliable mechanical support point for the connecting strap 710. Through the auxiliary fixing effect of the connecting strap 710, the problem of hats easily falling off in sports scenarios is effectively solved, while also taking into account the convenience and diverse needs of daily use, reflecting the dual consideration of functional expansion and user experience optimization in product design.

[0053] In this embodiment, the strap connection assembly 700 further includes a connecting ring 730, which is connected to the connecting strap 710 via the fixing member 720. The connecting ring 730 and the fixing member 720 are made of zinc alloy, while the connecting strap 710 is made of a flexible material. Through this structural design, the strap connection assembly 700 achieves a balance between connection reliability and user comfort during use through differentiated material selection and structural matching. The connecting ring 730 and the fixing member 720 are made of zinc alloy, which possesses both high strength and good formability, enabling them to withstand the tensile and torsional stresses generated when the connecting strap 710 is under stress. This ensures a stable connection between the connecting ring 730 and the connecting strap 710, and between the connecting strap 710 and the clamping element 100, preventing deformation or breakage and providing solid structural support for the entire strap connection assembly 700. Simultaneously, the corrosion resistance of zinc alloy can withstand the erosion from sweat and moisture during daily use, ensuring the long-term functionality of the connection parts. The connecting strap 710 is made of a flexible material, which fully utilizes its bendability and deformability. During the fixing process, it can adaptively adjust to the shape of the hat, improving comfort. Furthermore, the flexibility of the material can buffer external impacts, preventing damage to the hat or device itself when the connecting strap 710 is pulled. This combination of "rigid structural components + flexible connectors" ensures the mechanical stability of the connecting strap 710 connection through the zinc alloy components, while optimizing the user experience through the flexible strap. It synergizes with the connecting ring 730's connection function, further expanding the device's adaptability and practical value. The connecting ring 730 includes a ring base 731, a ring movable part 732, an elastic element 733, and a ring pin 734. The ring base 731 is rotatably connected to the ring movable part 732 via the ring pin 734, and the elastic element 733 achieves pre-tightening and normal closure of the connecting ring 730. When it is necessary to attach ropes or similar objects, the connecting ring 730 can be opened by pressing the movable part 732 of the hanging ring, thereby realizing the connection and suspension.

[0054] In this embodiment, the adjusting element 300 and the clamping element 100 are made of zinc alloy. Through the above structural design, when in use, the adjusting element 300 and the clamping element 100 are made of zinc alloy. This design choice ensures the core performance of the device from both structural performance and functional compatibility perspectives: zinc alloy has high strength and hardness, providing a stable structural foundation for the threaded transmission of the adjusting element (such as the cooperation between the threaded adjusting part 320 and the threaded receiving part 130), ensuring that deformation or wear is not easily caused during repeated tightening and adjustment, and guaranteeing the accuracy and long-term effectiveness of the clamping force adjustment; for the clamping element 100, the rigidity of the zinc alloy allows it to stably bear the force of the elastic element 200, forming a reliable clamping space in cooperation with the elastic element, while also supporting auxiliary structures such as the anti-slip pad layer 140, ensuring the stability of the overall frame. Furthermore, the good formability of zinc alloy facilitates the manufacture of complex detailed structures such as the first mounting structure 110 and the threaded receiving part 130, improving the machining accuracy and assembly compatibility of the components.

[0055] In this embodiment, the elastic modulus of the elastic element 200 is in the range of 190-210 GPa, providing a clamping force of 5-15 N. Through the above structural design, in use, the elastic modulus of the elastic element 200 is set to 190-210 GPa, and it can provide a clamping force of 5-15 N. This parameter design achieves precise adaptation in terms of both mechanical performance and practical function: the elastic modulus range of 190-210 GPa ensures that the elastic element has sufficient rigidity to stably transmit deformation force, while also giving it a moderate elastic deformation capability, enabling controllable deformation under the action of the adjusting element 300, thereby achieving flexible adjustment of the clamping force; while the clamping force range of 5-15 N provides an adaptation range for different types of hats (such as thin sun hats, thicker knitted hats, etc.)—a smaller clamping force can avoid damage to thin hats, while a larger clamping force can ensure the stable fixation of heavy hats, effectively balancing the reliability of clamping and the protection of the hat. Meanwhile, the matching design of the elastic modulus and clamping force works in conjunction with the threaded adjustment structure of the adjusting element 300, enabling the adjusting element to precisely control the clamping force within the range of 5-15N by finely adjusting the deformation of the elastic element, thus meeting the personalized clamping force requirements of users in different scenarios. This parameter setting is based on the material properties of the elastic element (such as the mechanical properties of manganese steel or stainless steel sheets) and also fully considers the type of hat and user experience in actual use, reflecting the precise combination of mechanical parameters and practical functions in the design.

[0056] In this embodiment, the coefficient of friction of the anti-slip pad 140 is greater than 0.4. Through the above structural design, the coefficient of friction of the anti-slip pad 140 is set to be greater than 0.4 during use. This parameter design enhances the clamping effect of the device in terms of both anti-slip performance and usability: the characteristic of a coefficient of friction greater than 0.4 ensures that the anti-slip pad 140 generates sufficient static friction when in contact with the hat surface, effectively resisting the tendency of the hat to slide during activities. Especially for hats made of smooth materials (such as silk or polyester), it can significantly improve the stability of the clamping and avoid the problem of falling off due to insufficient friction. At the same time, this coefficient of friction range ensures the effectiveness of the anti-slip effect while avoiding difficulty in taking the hat off or putting it on due to an excessively high coefficient of friction—when it is necessary to disassemble or adjust the hat, moderate friction can balance the need for fixation and ease of operation, preventing pulling damage to the hat surface during the process of taking it off or putting it on. This parameter works in synergy with the 5-15N clamping force range of the elastic element. Through the dual action mechanism of "clamping force + friction", the device can be adapted to both thin and heavy hats, and can provide reliable fixation for materials with different surface roughness. This further expands the applicable scenarios of the device and reflects the precise matching between the physical parameters in the design and the actual usage requirements.

[0057] In this embodiment, the number of support ribs 311 is 8-12, evenly distributed along the circumference. With this structural configuration, the 8-12 support ribs 311 evenly distributed along the circumference achieve a precise balance between uniform force transmission and structural stability. The 8-12 rib range avoids the problems of sparse support points and localized stress concentration caused by too few ribs, while preventing structural redundancy and weight increase caused by too many ribs. This ensures that the force exerted by the abutment end 310 on the deformation adjustment part 230 is evenly distributed through the multiple support ribs 311, making the deformation of the elastic element 200 more symmetrical and controllable, providing a stable foundation for precise adjustment of the clamping force. The evenly distributed circumference further ensures the consistency of force on each support rib 311. During the screwing of the adjustment element 300, it effectively avoids excessive local deformation of the elastic element or adjustment jamming caused by uneven force, ensuring smooth adjustment and linearly controllable changes in clamping force. This distribution pattern works in conjunction with the radial layout of the supporting ribs 311, which not only enhances the structural strength of the abutment end 310, making it less prone to deformation under long-term stress, but also improves the ease of processing through standardized spacing design, and is compatible with the overall modular structure of the device.
