Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically a frameless eyeglass that can be easily fixed by inserting double wires from the side. Background Technology

[0002] Rimless glasses have gained a significant share of the eyewear market in recent years due to their lightweight design, wide field of vision, and modern minimalist style. The core structure of traditional rimless glasses typically consists of nose pads, lenses, temples, and frame material, with the connection method between the lenses and temples directly affecting the product's functionality, durability, and user experience.

[0003] In early technical solutions, the connection between the lens and the temple was generally achieved using a screw-fixed structure: screw holes were pre-drilled at the edge of the lens, the stud was secured to the lens with screws, and the temple was then hinged to the stud. This design achieved structural stability through the rigid connection of the metal screws, and the adjustable nature of the screws allowed users to adjust the temple angle according to their needs, which once became the mainstream technical approach for rimless eyeglasses.

[0004] With advancements in materials science and processing technology, rimless eyeglasses are gradually moving towards ultra-thin and lightweight designs. The use of high-refractive-index lenses and lightweight materials such as titanium alloys has significantly reduced the overall weight of the glasses; however, the limitations of traditional screw-fixed structures are becoming increasingly apparent.

[0005] Assembly process dependence: Screw fixing requires precision drilling and tapping at the edge of the lens, which places extremely high demands on the processing accuracy of the lens material (especially resin lenses), and the assembly process requires the use of special tools, making it difficult to achieve automated production.

[0006] Structural stability challenges: During long-term use, the metal-metal contact surface between the screw and the screw hole is prone to loosening due to wear vibration, temperature changes, deformation or metal fatigue, and there is even a risk of the screw falling off.

[0007] Aesthetic design bottleneck: Exposed screw heads disrupt the overall visual continuity of the frame. Especially under the "invisible connection" concept pursued by frameless design, traditional structures are unable to meet the demand for minimalist aesthetics in the high-end market. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, this utility model provides a frameless glasses that can be easily fixed by side insertion with double wires. Through the synergistic effect of the elastic fork and the gradually widened slot, tool-free quick assembly is achieved while ensuring the long-term stability and aesthetic integrity of the connection structure.

[0009] This utility model provides a frameless eyeglass that can be easily fixed by a double-wire insertion from the side, including a nose pad, a lens, a post, and temples. The lens is symmetrically fixed on both sides of the nose pad, the post is fixed on the outer end of the lens, and the temples are connected to the post. The feature is that a slot is provided on the outer end of the lens, and an elastic fork is fixedly provided on the post. The elastic fork is inserted into the inside of the slot, and the width of the inner end of the slot is greater than the width of the outer end of the slot.

[0010] In a preferred embodiment, the elastic fork includes a fixed end and a fork end, the temple is connected to the fixed end, and the fork end is inserted into the slot.

[0011] In a preferred embodiment, the shift fork end includes two spring pieces disposed on the fixed end.

[0012] In the preferred embodiment, the two spring clips are arranged in a Y-shape.

[0013] In a preferred embodiment, the two spring sheets are arranged in parallel, and a wedge block is slidably disposed between the two spring sheets, with one end of the small end of the wedge block located inside the spring sheets.

[0014] In a preferred embodiment, the two spring pieces are arranged in parallel, and a fixing block is provided on the fixed end side and between the two spring pieces. A sliding groove is provided between the fixing block and the two spring pieces, and a wedge block is slidably arranged in the sliding groove. One end of the small head of the wedge block is located on the inner end side of the sliding groove.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] The side-insertion double-line fixing design completely eliminates the traditional screw fixing structure, enabling tool-free and rapid connection of lens, socket, and temple. Users or manufacturers can directly complete the assembly by inserting the flexible fork into the slot, significantly simplifying the assembly process and reducing the difficulty of manufacturing.

[0017] The slot's gradient design, wider inside and narrower outside, combined with the deformation characteristics of the elastic fork, provides guidance during insertion and achieves self-locking after insertion. This mechanical engagement effectively prevents the temples from accidentally falling off and improves the overall structural stability of the glasses.

[0018] The frameless design, combined with an integrated flexible fork structure, significantly reduces the number of parts and overall weight, improving wearing comfort; the hidden connection mechanism eliminates the abruptness of traditional exposed screws, conforming to the modern minimalist aesthetic trend of eyewear.
