Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, specifically to personalized 3D printed lightweight eyeglass frames. Background Technology

[0002] Eyeglasses are lenses encased in a frame and worn in front of the eyes to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct various vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, or strabismus. Eyeglasses consist of lenses and frames, and are divided into four types: nearsighted glasses, farsighted glasses, presbyopia glasses, and astigmatism glasses.

[0003] For example, the authorized announcement number "CN214669897U" describes a lightweight metal eyeglass frame that features V-shaped limiting blocks and V-shaped limiting grooves to make the connection between the eyeglass frame and the lenses tighter. Existing lightweight metal eyeglass frames are made entirely of metal, which has a high density and is quite heavy when worn on the bridge of the nose. Moreover, metal is prone to green rust over time, affecting its appearance and potentially interfering with the wearer's vision, resulting in insufficient lightweight and rust resistance of the entire metal eyeglass frame.

[0004] Meanwhile, existing lightweight metal frames have two extended temples attached to the back of the frame. The temples need to be hung behind the ears to hold the front of the frame in place. Conventional temples rely on friction to hold the ears in place. Some people have soft ear bones or small auricles, so the thin temples are not strong enough to support the frame, causing the glasses to slip off frequently. Utility Model Content

[0005] This invention addresses the problems of existing lightweight metal eyeglass frames, such as the tendency for metal to develop green rust over time, affecting aesthetics and interfering with the wearer's vision, resulting in insufficient lightweight and rust resistance, and the instability of thin temples for people with soft ear bones or small earlobes, causing the glasses to frequently slip off. The proposed invention is a personalized 3D-printed lightweight eyeglass frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a personalized 3D printed lightweight eyeglass frame, including a connecting frame, a lens frame, and a crossbeam. Two lens frames are fixedly connected to the inner side of the connecting frame, and a crossbeam is fixedly connected to the outer wall of the two connecting frames. Extension blocks are fixedly installed at both ends of the side wall of the connecting frame. Hinges are rotatably installed on the inner side of the two extension blocks, and flip blocks are rotatably connected to the outer side of the hinges.

[0007] In this design, the connecting frame, mirror frame, and crossbeam are a single 3D printed structure, ensuring the overall structural strength. The single 3D printing can be either photopolymer 3D printing or fused deposition modeling 3D printing technology. The extension block is printed synchronously with the connecting frame, and the hinge is a pre-customized damping hinge that is embedded in the reserved mounting slot of the extension block. The hinge can also rotate with the flip block.

[0008] Preferably, eyeglass temples are fixedly installed on the side walls of the two flipping blocks, and multiple weight-reducing holes are fixedly opened on the inner side of the two eyeglass temples.

[0009] Preferably, the other end of the two temples is fixedly connected to an anti-slip sleeve, the outer wall of the other end of the two temples is rotatably connected to a flip shaft, and an anti-slip strip is rotatably connected below the two flip shafts.

[0010] This design features a rubber anti-slip sleeve that increases friction between the ear and the temples, reducing the likelihood of the temples slipping. The rotating shaft allows the inwardly concave plastic anti-slip strips to rotate back and forth on the outer wall of the temples. When the glasses are not worn, the two anti-slip strips are attached to the outer wall of the anti-slip sleeve. When the anti-slip sleeve is stuck behind the ear, rotating the two anti-slip strips forward allows them to clamp in front of the ear, further securing the glasses.

[0011] Preferably, the sidewalls of the two anti-slip strips are movably connected to the outer wall of the anti-slip sleeve.

[0012] Preferably, the inner walls of the two frames are fixedly connected with nose pads, and the two nose pads are arranged in a mirror image of each other.

[0013] This feature includes a silicone nose pad that fits snugly above the bridge of the nose to support the entire frame.

[0014] Preferably, the front ends of the two temples are rotatably connected to the two sides of the connecting frame via hinges.

[0015] The personalized 3D-printed lightweight eyeglass frame proposed in this utility model has the following advantages: the connecting frame, the eyeglass frame, and the beam are integrated 3D-printed structures, ensuring the overall structural strength; the extension block is printed synchronously with the connecting frame; the hinge is a pre-customized damping hinge that is embedded in the reserved mounting groove of the extension block, and the hinge can rotate with the flip block; the weight-reducing holes are multiple round holes hollowed out inside the temples made of multiple 3D-printed materials, and each weight-reducing hole can appropriately reduce the weight of the eyeglass frame and reduce wearing pressure; and the non-metallic 3D-printed material is lightweight and does not contain metal, making it difficult to rust.

[0016] The anti-slip sleeve is made of rubber, increasing the friction between the ear and the temple, reducing the chance of the temple slipping off. The flip axis can rotate the inwardly concave plastic anti-slip strips back and forth on the outer wall of the temple. When the glasses are not worn, the two anti-slip strips are attached to the outer wall of the anti-slip sleeve. When the anti-slip sleeve is stuck behind the ear, flipping the two anti-slip strips forward can clamp them in front of the ear, further reinforcing the glasses. It can also be worn more securely and is less likely to fall off for users with soft ear bones or small earlobes. Attached Figure Description
