Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, specifically to a lightweight, sweat-resistant aluminum-magnesium alloy eyeglass frame. Background Technology

[0002] With the increasing number of people wearing glasses, consumers are placing higher demands on the materials, weight, and durability of eyeglass frames.

[0003] In the prior art, Chinese Patent No. CN221746384U discloses a high-strength eyeglass frame, which is composed of an eyeglass frame body. The eyeglass frame body includes a frame, a left temple and a right temple. The left temple is hinged to the left side of the frame, and the right temple is hinged to the right side of the frame. The frame is provided with a nose pad. The length of the left temple and the right temple both extend forward and backward. The eyeglass frame body is made of titanium alloy. By adopting the above solution, a high-strength eyeglass frame is provided that can reduce the weight of the eyeglass frame, improve wearing comfort, and improve the strength of the eyeglass frame at the same time.

[0004] Based on the above materials, existing eyeglass frames are usually heavy, which can cause local pressure when worn for a long time. Moreover, they are easily corroded by sweat after prolonged wear. Corrosive components such as chloride ions and lactic acid in sweat can easily penetrate the protective layer, causing pitting corrosion and ion precipitation in the base metal. This not only shortens the lifespan of the eyeglass frames but may also cause skin allergies. In addition, the opening and closing degree of the temples is relatively fixed and cannot be adjusted as needed, affecting wearing comfort. Therefore, we propose a lightweight, sweat-resistant, corrosion-resistant aluminum-magnesium alloy eyeglass frame. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight, sweat-resistant aluminum-magnesium alloy eyeglass frame to solve the problems mentioned in the background art. Existing eyeglass frames are usually heavy, which can cause local pressure when worn for a long time. Moreover, they are easily corroded by sweat after prolonged wear. Corrosive components such as chloride ions and lactic acid in sweat can easily penetrate the protective layer, causing pitting corrosion and ion precipitation in the base metal. This not only shortens the service life of the eyeglass frame but may also cause skin allergies. In addition, the opening degree of the temples is relatively fixed and cannot be adjusted as needed, affecting wearing comfort.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight anti-sweat corrosion aluminum-magnesium alloy eyeglass frame, comprising a frame body, the frame body being composed of a frame, temples, and other components, and the frame body being made of lightweight aluminum-magnesium alloy. The outer wall of the frame body is provided with an anti-sweat corrosion structure to prevent corrosion from sweat stains. The anti-sweat corrosion structure includes a micro-arc oxidation ceramic bottom layer, a chelated modified transition barrier layer, and a hydrophilic drainage protective layer disposed on the surface of the frame body. The temple ends are provided with an adjustment structure for adjusting the opening degree.

[0007] Furthermore, the temple is provided with uniformly distributed weight-reducing cavities, and the cross-section of the weight-reducing cavities is designed in a honeycomb shape.

[0008] Furthermore, the micro-arc oxidation ceramic bottom layer, the chelated modified transition barrier layer, and the hydrophilic guiding protective layer are stacked sequentially from the inside to the outside on the surface of the main body of the eyeglass frame. The surface of the micro-arc oxidation ceramic bottom layer is provided with honeycomb-shaped nanopores, and the nanopores are filled with nano-silica anti-corrosion particles.

[0009] Furthermore, the chelated modified transition barrier layer is composed of chelated organosilicon resin and nano-montmorillonite, and the hydrophilic flow-guiding protective layer is made of plasma-activated fluorinated modified acrylic resin, with hydrophilic micro-nano grooves on the surface of the hydrophilic flow-guiding protective layer.

[0010] Furthermore, the outer wall of the temple is fitted with a protective sleeve, and the protective sleeve is made of fluorine-modified silicone rubber.

[0011] Furthermore, the adjustment structure includes an opening and closing limiting gear fixedly installed on the side wall of the pile head, an elastic abutment post is provided on the side wall of the end of the mirror temple, and a limiting post is provided on the outer wall of the elastic abutment post, and the mirror temple is hinged to the pile head.

[0012] Furthermore, two sets of opening and closing limiting gears are symmetrically arranged at the end of the pile head, and the end of the mirror temple is located between the two sets of opening and closing limiting gears. Two sets of limiting posts are symmetrically arranged at the end of the elastic abutment post, and the limiting posts are cylindrical in design, and the limiting posts abut against the tooth grooves on the outer wall of the opening and closing limiting gears.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This lightweight, sweat-resistant aluminum-magnesium alloy eyeglass frame uses a lightweight aluminum-magnesium alloy material combined with a honeycomb-shaped weight-reducing cavity design inside the temples, which significantly reduces the overall weight of the frame, reduces local pressure caused by long-term wear, and improves wearing comfort. At the same time, through a three-layer composite anti-sweat corrosion structure of micro-arc oxidation ceramic bottom layer, chelated modified transition barrier layer and hydrophilic diffusing protective layer, it can effectively block the penetration of corrosive components such as chloride ions and lactic acid in sweat, avoid pitting corrosion and ion precipitation of the base metal, extend the service life of the frame, and reduce the risk of skin allergies.

[0014] 2. By combining the chelated organosilicon resin and nano-montmorillonite composite properties of the chelated modified transition barrier layer, and the hydrophilic micro-nano groove design of the hydrophilic drainage protective layer, the bonding stability between the protective layer and the substrate can be enhanced, and sweat can be quickly wicked away, further improving the anti-sweat corrosion effect. In addition, the fluorine-modified silicone rubber protective sleeve on the outer wall of the temple can further optimize the wearing feel, while also helping to enhance the anti-sweat and anti-slip performance.

[0015] 3. By adjusting the design of the opening and closing limit gears and the elastic abutment post and limit post in the structure, the opening and closing degree of the temples can be adjusted in multiple positions to adapt to the facial contours of different wearers, solving the problem of fixed opening and closing degree of existing temples and further improving the fit and comfort of wearing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1 , Figure 5 and Figure 6 The present invention provides the following technical solution: a lightweight anti-sweat corrosion aluminum-magnesium alloy eyeglass frame, comprising a frame body 1, the frame body 1 being composed of a frame 2, a post 201 and temples 3, and the frame body 1 being made of lightweight aluminum-magnesium alloy. The outer wall of the frame body 1 is provided with an anti-sweat corrosion structure for preventing sweat corrosion. The anti-sweat corrosion structure includes a micro-arc oxidation ceramic bottom layer 6, a chelated modified transition barrier layer 7 and a hydrophilic guiding protective layer 8 disposed on the surface of the frame body 1; the temples 3 are provided with uniformly distributed weight-reducing cavities 302 inside, and the cross-section of the weight-reducing cavities 302 is designed in a honeycomb shape.

[0020] like Figure 6As shown, the micro-arc oxidation ceramic bottom layer 6, the chelated modified transition barrier layer 7, and the hydrophilic guiding protective layer 8 are stacked sequentially from the inside to the outside on the surface of the frame body 1. The surface of the micro-arc oxidation ceramic bottom layer 6 is provided with honeycomb-shaped nano-micropores, and the nano-micropores are filled with nano-silica anti-corrosion particles. The chelated modified transition barrier layer 7 is composed of chelated organosilicon resin and nano-montmorillonite. The hydrophilic guiding protective layer 8 is made of plasma-activated fluorine-modified acrylic resin, and the surface of the hydrophilic guiding protective layer 8 is provided with hydrophilic micro-nano grooves. The outer wall of the temple 3 is fitted with a protective sleeve 301, and the protective sleeve 301 is made of fluorine-modified silicone rubber.

[0021] First, the frame body 1 is made of lightweight aluminum-magnesium alloy, while the temples 3 feature a uniformly distributed honeycomb-shaped weight-reducing cavity 302. This design maximizes the reduction of overall weight while ensuring the structural strength of the frame, minimizing pressure on the head and ears during wear and laying the foundation for lightweight comfort. Second, the anti-sweat corrosion structure employs a three-layer design: a micro-arc oxidation ceramic base layer 6, a chelated modified transition barrier layer 7, and a hydrophilic drainage protective layer 8, stacked sequentially from the inside out, forming a comprehensive protection system. The micro-arc oxidation ceramic base layer 6 is generated on the surface of the aluminum-magnesium alloy substrate through a micro-arc oxidation process. Its honeycomb-shaped nanopores are filled with nano-silica anti-corrosion particles, which can directly block sweat. The corrosive components in the liquid come into contact with the substrate, forming the first line of corrosion protection. The middle chelated modified transition barrier layer 7 is composed of chelated organosilicon resin and nano-montmorillonite, which can not only bond tightly with the micro-arc oxidation ceramic bottom layer 6 to enhance the overall adhesion of the protective layer, but also adsorb a small amount of corrosive ions that permeate from sweat through chelation, preventing them from spreading further. The outermost hydrophilic diversion protective layer 8 is made of plasma-activated fluorine-modified acrylic resin. Its surface hydrophilic micro-nano grooves can quickly adsorb and divert sweat adhering to the surface of the frame, reducing the time that sweat stays on the surface and reducing the risk of corrosion from the source. The three-layer structure works together to achieve a highly efficient anti-sweat corrosion effect.

[0022] Example 2: Please refer to Figures 1-5 Based on Embodiment 1, an adjustment structure is also disclosed, the specific structure of which is as follows: The end of the temple 3 is provided with an adjustment structure for adjusting the opening degree. The adjustment structure includes an opening and closing limiting gear 4 fixedly installed on the side wall of the pile head 201. The side wall of the end of the temple 3 is provided with an elastic abutment post 5, and the outer wall of the elastic abutment post 5 is provided with a limiting post 501. The temple 3 is hinged to the pile head 201. Two sets of opening and closing limiting gears 4 are symmetrically arranged at the end of the pile head 201, and the end of the temple 3 is located between the two sets of opening and closing limiting gears 4. Two sets of limiting posts 501 are symmetrically arranged at the end of the elastic abutment post 5, and the limiting posts 501 are cylindrical in design, and the limiting posts 501 abut against the tooth grooves on the outer wall of the opening and closing limiting gear 4.

[0023] The adjustment structure achieves adjustable opening and closing of the temple 3 through the cooperation of the opening and closing limiting gear 4, the elastic abutment post 5, and the limiting post 501. The temple 3 and the post head 201 are connected by a hinge, allowing the temple 3 to rotate around the hinge point to open and close. Two sets of opening and closing limiting gears 4 are symmetrically fixedly installed on the side wall of the post head 201. The end of the temple 3 is located between the two sets of opening and closing limiting gears 4, and the end of the elastic abutment post 5 on the side wall of the end of the temple 3 is symmetrically provided with two sets of cylindrical limiting posts 501. The limiting posts 501 and the tooth grooves on the outer wall of the opening and closing limiting gear 4 always maintain abutment. When it is necessary to adjust the opening and closing of the temple 3, it can be adjusted outward or... When an external force is applied to the inner side to push the temple 3, the temple 3 rotates around the hinge point. At this time, the elastic abutment post 5 is squeezed by the opening and closing limiting gear 4 and undergoes elastic deformation, causing the limiting post 501 to disengage from the current tooth groove and slide into the adjacent tooth groove. When the external force is removed, the elastic abutment post 5 returns to its deformation and pushes the limiting post 501 to re-engage in the corresponding tooth groove, thereby fixing the position of the temple 3. Through the engagement and cooperation of the limiting post 501 with different tooth grooves, the opening and closing degree of the temple 3 can be adjusted in multiple positions to suit the facial contours and wearing habits of different wearers, solving the problem of fixed opening and closing degree of traditional frames and improving wearing adaptability and comfort.
