Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, specifically to an elastic eyeglass frame. Background Technology

[0002] Eyeglass frames are an essential component of eyeglasses, primarily serving to support the lenses. Aesthetically pleasing frames also contribute to their appearance. Materials mainly include metal, plastic or resin, and natural materials. Based on style, they can be categorized as full-rim, semi-rimless, and rimless. Requirements include certain hardness, flexibility, elasticity, wear resistance, corrosion resistance, lightweight, a glossy finish, and good color. The metal materials used to make eyeglass frames are almost always alloys or metals with surface treatments. A good frame should be made of stable, safe, reliable, and skin-friendly materials, and should be lightweight, sturdy, and not deformed.

[0003] The existing eyeglass frames are connected to the temples on both sides by hinges, and the hinge angle is generally less than or equal to 90 degrees to ensure the use of the glasses and the wearer. However, this design can cause problems such as ear pinching and slipping when used by people with different head sizes. At the same time, the original metal or plastic eyeglass frames are not lightweight enough, and wearing them for a long time can easily cause fatigue. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an elastic eyeglass frame. The frame, temples, and elastic hinges are made of a novel nano-titanium metal, which increases tensile strength, reduces surface activity, and makes it less susceptible to oxidation or corrosion, making it suitable for long-term use. Simultaneously, the novel nano-metal material reduces the weight of the eyeglass frame compared to frames made of ordinary materials, resulting in a more aesthetically pleasing and comfortable fit. Furthermore, the elastic hinges utilize an integrated, ultra-elastic hinge structure with a geometric design: an inner arc and an outer square hollow design, conforming to the curve behind the ear, distributing pressure points, and eliminating problems such as ear pinching and slippage.

[0008] The elastic hinge includes a fixed rod, an elastic ring is fixedly connected to one side of the fixed rod, and a positioning block is fixedly connected to one side of the elastic ring.

[0009] Preferably, the inside of the pile head is connected and fixed to the positioning block by bolts, and a fixing groove is provided on one side of the temple, and the inside of the fixing groove is connected and fixed to the fixing rod by bolts.

[0010] Preferably, the left and right sides of the connecting frame are fixedly connected to the mirror frame, and the elastic hinge forms a detachable structure with the post head and the temple.

[0011] Preferably, the two half-gears are symmetrically installed inside the connecting frame, and the nose bridge frame and the half-gears form an integral structure.

[0012] Preferably, the central axis of the fixing rod is perpendicular to the central axis of the positioning block, and the temple can be adjusted by an elastic ring.

[0013] Preferably, the connecting frame is made of silicone material with good ductility, and the inner side of the nose bridge frame is provided with a nose pad made of soft silicone material.

A positioning piece is provided on the inner side of the post head 2, and the positioning block 303 is fixedly connected to the positioning piece by bolts. This detachable structure facilitates the replacement of eyeglass frame components and makes it more convenient to use. A fixing groove 9 is provided on one side of the temple 4. The size of the fixing groove 9 is the same as the size of the fixing rod 301. The fixing rod 301 is embedded into the fixing groove 9, and the interior of the fixing groove 9 is fixed to the fixing rod 301 by bolts, facilitating the disassembly and replacement of the elastic hinge 3. The frame 1 is fixedly connected to both sides of the connecting frame 6. The elastic hinge 3, post head 2, and temple 45 form a detachable structure. Two half-gears 7 are symmetrically installed inside the connecting frame 6, and the nose bridge 8 and half-gears 7 form an integrated structure. The connecting frame 6 is made of highly malleable silicone material. The frame 1 can be folded inward through the two half-gears 7, making it easy to put the folded semi-finished silver frame into the packaging box for storage, making the storage space of the eyeglass frame more compact. The nose bridge 8 has a soft silicone nose pad 10 on the inside. At the same time, the spacing of the nose pad 10 can be adjusted according to the two half-gears 7, making it convenient for people with different nose bridge widths to use.
